1 1 General Unless noted, this manual refers to DSP-223 operating software 2.6. The VegaDSP-223 tone-remote adapter provides remote control of two-way-radio base stations using any Vega tone remote consoles. The DSP-223 is also compatible with other consoles using the industrystandard sequential tone-keying format. The DSP-223 connects to the tone remote control console(s) using any voice-grade transmission medium such as a microwave link, a leased telephone line, or a twisted-pair 600-ohm line. All DSP-223s are capable of decoding the PTT (push-to-talk/transmitter-on) tone sequence and the voiceplus-tone signals during transmission. Control tones in the voice-plus-tone signal are filtered from the transmitted voice. All models are prepared for jumper-plug conversion from two-wire-line operation to four-wire-line operation. In the four-wire mode, the panels are full duplex capable. The DSP-223 provides the following features: PTT Relay Monitor Relay 99-digit display PTT, Monitor, and Power LED indications F1 and F2 Relays (programmable to any function tone or Revert to F1) 6 digital outputs for channel selection, completely programmable per function tone CTCSS generation (64 frequencies) Hardware and software gain control Local handset port for monitoring activity and transmission back to base or to radio Front panel test points and level set potentiometers RS-232C port on front panel for configuration via Windows application Two PTT modes and three monitor modes Eight selectable PTT frequencies Ability to pass-through to a second tone adapter with 400ms built in delay line Relays can be placed in any of four groups for separation of function Single Function tone recognition (16 function tones) Dual function tone recognition (100 function tones) Morse Code Encoder for Automatic station identification Automatic Gain Control Function Tone lock-out RX Audio Squelch Voter Status Tone Alarm Beeps Pre-Emphasis 3.5kHz Low Pass Filter All audio inputs and outputs are transient protected. The DSP-223 line transformers are not designed to operate on lines carrying direct current. If a DC voltage is on the line, isolate with external capacitors. If the line termination must conduct direct current, install a 600:600-ohm transformer designed for the current involved. 1.1 DSP-223 Accessories Several optional accessories are available for the DSP-223.

Two connectors are provided to connect the unit to power. The first is a 2.5mm plug receptacle on the rear left of the unit. The positive terminal is the center conductor. The second power connection option is the DB25 connector. Figure 1 shows the pin out of this connector. Connect an external 12 to 16 volt DC supply with the positive connected to Pin 20 and the Ground connected to Pin 7. 13 12 11 10 9 8 7 6 5 4 3 2 25 24 23 22 21 20 19 18 17 16 15 14 DB25 Rear Panel Connector 1 1-PTT NC 14-PTT NO 2-PTT COM 15-MON NC 3-MON NO 16-MON COM 4-F1 NC 17-F1 NO 5-F1 COM 18-F2 NC 6-F2 NO 19-F2 COM 7-GROUND 20-+POWER 8-DIG 0 21-DIG 1 9-DIG 2 22-DIG 3 10-DIG 4 23-DIG 5 11-CTCSS 24-RX+ 12-RX25-TX+ 13-TX- Figure 1 DB25 Rear Connector Pin-out 2.2 DSP-223 to Console Line Connection The line connector is the right most connector on the rear of the DSP-223.

They are transmitted back down the line to the console. Pins 3&6 of the Line connector are inputs from the console and the audio present on this pair will be sent to the radio. 7) 8) Ground Connector View Figure 2 Line Connector Pin-out There are several jumper selections that must be made for the line connection. according to your connection requirements. 2 Wire / 4 Wire Selection: 2 Wire 4 Wire J20 A B J21 A B RX Termination: 600 Ohms 10k Ohms Set the jumpers J19 A B The RX termination should be placed in position “A” on J19 for a single unit at the end of a line. If multiple units are connected in parallel, only one unit should have the RX Termination jumper in the “A” position. Set J19 to “B” position for 2-wire operation. 2.3 DSP-223 to Radio Connection 2.3.1 TX Audio Connection The DSP-223 has a number of options when connecting it to the radio. Set the jumpers according to the method outlined in your radio’s owner manual. Tone Remote 3 Connection Type: Balanced 600 Ohm: Single Ended Low-Impedance: J14 J15 J22 J23 B A B A B A B A If the microphone input of the radio is high-impedance, shielded cable is recommended. If the radio has a high-level microphone input, move J26 to the B position, otherwise J26 should stay in the A position. 1 The balanced 600-Ohm option is only available on the DB25 connector on the rear panel; see Figure 1 for the pin-out. If the TX Audio is set to single ended mode, it can be used from the TX+ pin on the DB25 or can be accessed on the smaller 6-pin rear connector. The 6 Pin connector pin-out appears in Figure 3. 1) Ground 3) PTT-COM 5) Radio TX 2.3.2 RX Audio Connection Set the following jumpers for the type of receive audio required: Output Type: Balanced 600 Ohm: Single Ended: Receive Input Impedance: J24 J25 J27 B A B A B A J12 J13 2 3 4 5 6 2) PTT-NO 4) Radio RX 6) Power 6 Pin Rear Connector Pinout Figure 3 6 Pin Radio Connector Pin-out 8 Ohms A B (for a speaker output) 600-Ohm B A 10k Ohm B B Connect the radio receiver audio output if balanced to pins 12 and 24 of the rear panel DB25. If the receive audio is single ended pin 24 of the rear DB25 or pin 4 of the rear 6 pin connector can be used. The audio source must be after the squelch circuit, to prevent sending continuous noise to the remote console. If a high-impedance point in the receiver is used, shielded cable is recommended. Note: When the speaker output is used, the radio volume control will affect the audio levels of the DSP-223. 2.3.3 PTT Connection Connect the radio PTT circuit to the PTT relay contact terminals. Connections on the DB25 or the 6 pin connectors may be used. Usually the common of the relay contact switch is grounded and the normally open contact connects to the PTT input. It is also possible to ground the common of the relay internal to the unit by bridging the pads of JP2 with wire and soldered closed. 2.3.4 Monitor Connection Connect the radio MON circuit to the MON relay contact terminals of the DB25 connector. Usually the common of each relay contact switch is grounded and the normally open contact connects to the MON input. It is also possible to ground the common of the relay internal to the unit by bridging the pads of JP3 with wire and soldered closed. 4 Vega DSP-223 2.3.5 Radio Frequency Control The DSP-223 provides two relays that may be used for radio channel control. F1 and F2 contacts may be connected through the rear DB25 connector. Usually the common of each relay contact switch is grounded and the normally open contact connects to the radio frequency-control terminals. In addition to the two standard relay closures, six lines of digital I/O are available. These lines are opencollector transistor outputs. They can be programmed on a per line basis to generate any of 64 combinations. A programmed option is also available that does not change the digital I/O. Each line is active low and may be jumper selected to pull up to either +5v or the power supply voltage (minimum +12v). Jumper J16 is used to select the pull up voltage. The A position pulls to the power supply value and B pulls up to +5v. Refer to Section 4.2.2.9.5 Digital Output for programming the digital outputs. 2.3.6 CTCSS Connection The DSP-223 is designed to generate a full range of CTCSS frequencies. Each function tone can be assigned its own CTCSS frequency for PTT operation or a number of CTCSS tones can be set using different function tones. A single ended, capacitor coupled, low impedance output is available on pin 11 of the rear panel DB25 connector. 2.4 Handset Connection The Telex Handset (P/N 249248) may be connected to the DSP-223 to monitor receive and transmit audio. When the handset PTT switch is pressed, the DSP-223 will be key up the radio on the existing frequency and the handset microphone audio will be transmitted. Pressing the PTT-IC button on the front panel provides an intercom connection between the DSP-223 and the tone remote console. 2.5 Digital Expansion Port The Digital Expansion Port on the rear panel of the DSP-223 provides a second serial communications connection for use in controlling various base station radios. A plug-in serial add-on PCB must be installed to enable this connector. This port is configured as a function of the specific application and the data is restricted to the control of specific radios. It is not intended as a general communications port to a PC. Tone Remote 5 3 Level Settings Once the unit is connected into the system, the level potentiometers can be set as shown in Table 1. 3.1 Line Receive Level Adjust Procedure The line RX level is the first level that must be set because all of the tone decoding is based on this level. Connect an Oscilloscope, RMS voltmeter, or dBm meter to Ground (TP-12) and Line RX audio (TP-2) test points on the front of the DSP-223. Inject the known highest signal level into the line receive circuitry. An external generator or a console can generate this with a test tone capability. Using Table 1, find the value of the injected signal level in the left most column (Actual RX Input (dBm)). In the case of the DSP223 being connected as a standard tone remote, the MAX input +10dBm column shows the level to adjust the RX Line Potentiometer to. This assumes that the standard +10dBm Guard Tone will be used.

On 1) Place a known signal level into the RX terminals of the Vega device being setup. Determine the maximum signal level that the device will see. This table supports +10 and 0 dBm the row of the injected 2) 3) Using the values from #1 and #2, Lookup #1 in the left column and move to the grouping for #2 signal level, find the 4) Set the RX pot for the value in the table column that matches the Table 1 measurement units of the device attached to the Line RX level test points on the front panel. Adjust the Line RX Potentiometer (R68) until it is close to the value listed in the table. This will allow the unit to work over its entire range without saturating the ADC. Note that this measurement is a signal level measurement of the voltage that is supplied to the ADC used by the DSP to decode the various required tones. 3.1.1 Revision G PCB’s with J17 Starting with PCB Revision G, jumper J17 has been added to provide a wider decode range. With J17 in the “A” position the DSP223 will perform like previous versions. When J17 is in the “B” position, a 6dbm gain is added to the input of the ADC after PTT is engaged. Setup is different with J17 in “B”. When the DSP223 is in PTT, adjust the Line RX Potentiometer (R68) for –15dbm at Line RX audio (TP-2) test point. 6 Vega DSP-223 3.2 Radio TX Level Adjust Procedure Due to the large range of input requirements for the radios that can be connected to the DSP-223, there is not a prescribed way of setting the Radio TX levels. Radio TX test points (TP-5 & TP-6) on the front panel of the DSP-223 provide a location to measure the actual value being placed onto the radio TX inputs. The Radio TX gain potentiometer (R7) can be used to adjust these levels. Note if the unit is placed into single ended mode with jumpers J14, 15, 22, and 23 the Radio TX+ should be measured with respect to ground. The user also has the option of placing J26 into the “A” position to decrease the output of the TX line by a factor of 10. The final adjustment should allow for undistorted audio to be transmitted for the full range of transmission levels at the desired deviation. Soldering JP6 together will increase the radio TX output adjustment range. 3.3 Radio RX Level Adjust Procedure The Radio RX level input to the DSP-223’s ADC can be measured by connecting an Oscilloscope or Meter to the ground and Radio RX test jack (TP-3) on the front of the unit. The maximum expected receive level should be set so that the measurement at the test points is approximately 3.4 volts peak-topeak or 1.2 volts RMS. This insures that the receive audio from the radio will not overdrive the input circuitry of the DSP-223. The usage of Table 1 can help facilitate this by following the directions for setting the Line RX levels. If the radio will not be generating a level above 0dBm, the 5-7 columns of the table can be used with a known input value to set the maximum level seen by the ADC. If the radio max level output will be below 0 dBm the Radio RX (R98) gain can be set higher to accommodate this. 3.4 Line TX Level Adjust Procedure The Line TX level is the last item that should be adjusted. With the unit connected to the 600 Ohm line, connect an oscilloscope, meter reading true RMS, or a meter with an output in dBm to the Line TX test points (TP-7 & TP-8) on the front of the DSP-223. There are three ways to generate the required test tone for setting the levels. The easiest is to “double click” the IC PTT button on the front panel. A 1minute 0dBm test tone will be sent on the Line and Radio TX lines. Pressing the IC PTT button again during the tone output will turn off the output. The second option, with the receive levels already set and a console capable of generating DTMF tones onto the Line RX pair, press “*0#8”. A 15 second, 1kHz, 0dBm tone will be placed on the TX line pair. The third method to generate the tone is to move the test jumper, J11 to the “B” position. As long as the test jumper is in the “B” position, a 0dBm 1kHz tone will be placed on the TX line pair. This does require opening the case. Adjust the Line TX Potentiometer (R12) until the measured voltage is 2.2 Volts peak-to-peak, 0.77 volts RMS, or 0dBm. Soldering JP7 together will increase the Line TX output adjustment range. 3.5 CTCSS Level (Continuous Tone coded Squelch) The CTCSS Level can be measured by connecting an oscilloscope or RMS meter to the ground and CTCSS test point (TP-13) on the front of the DSP-223. With the radio connected to the CTCSS output, have the remote console key up so that CTCSS is present. Adjust the CTCSS Potentiometer (R149) until the level is as desired. 3.6 DSP –223 Detection Frequencies The DSP-223 has been factory-tuned to the following frequencies. The user of the DSP-223 has no ability to change the detection frequencies as they are coded into the software. However any actual function or output can be made to work with any existing programmed frequency. Please consult the factory for special requirements for frequency selections. Guard tone/PTT Tone: 2175 Hz MON Function Tone: 2050 Hz Frequency Select Function Tones (where used) F1: 1950 Hz F2: 1850 Hz F3: 1750 Hz F4: 1650 Hz F5: 1550 Hz F6: 1450 Hz F7: 1350 Hz F8: 1250 Hz F9: 1150 Hz F10: 1050 Hz F11: 950 Hz F12: 850 Hz F13: 750 Hz F14: 650 Hz F15: 550 Hz F16: 450 Hz Tone Remote 7 4 Programming and Operation All programming for the DSP-223 is through an RS-232C serial port located on the front panel of the unit. Programming kit (P/N DSP223PRG) may be purchased separately from the DSP-223 and installed on a Windows 95 or newer computer. The latest DSP-223 operating software and Windows® application may also be down loaded from www.vega-signaling.com/dspsoftware.htm 4.1 Software Installation The Windows® application file is included on the VEGA Product Information CD provided with the DSP-223. Launch the CD and click on Firmware – then click on DSP-223. Follow the instructions for saving the file to the PC. When the application starts, an opening screen as shown in Figure 4 should appear. Figure 4 Windows Programming Main Screen 4.2 Windows® Application Software Operation 4.2.1 Select a Serial Port Clicking Com Port on the main menu screen opens the dialog box shown in Figure 5. Select either Com1 or Com2 and then click OK to close the dialog box. The Windows® application will set the serial port configuration. A 9 pin serial cable is provided to connect the DSP-223 and the PC. NOTE: The selected port is not saved and will default to Com1 each time the software is run. Figure 5 Serial Communications Port Screen 8 Vega DSP-223 4.2.2 DSP-223 Configuration Each button and programming field is described in the sections that follow. 4.2.2.1 Function Tone Mode In the upper left corner is a selection for single or dual function tone mode. Single function tone mode requires that the controlling console generate its Guard tone and then a single 40ms function tone. Dual function tone mode requires that the controlling console generate the Guard tone and then two consecutive function tones, which are then combined to form a 00-99 function tone. The standard function tones and their frequencies are shown in the following table. Function Tone Number Frequency (Hz) Function Tone Number Frequency (Hz) F1 F2 F3 F4 F5 F6 F7 F8 1950 1850 1750 1650 1550 1450 1350 1250 F9 F10 F11 F12 F13 F14 F15 F16 1150 1050 950 850 750 650 550 450 Dual function tones use tones F1-F10 and construct the final function tone value by combining the first received tone as the tens digit and the second received tone as the ones digit. F10 is used as a zero. For example: Function tone 9 would be transmitted as F10-F9, Function tone 43 would be F4-F3, and so forth. It is very important that DSP-223 be programmed for the type of signaling that is being sent from the controlling consoles. It is possible to put the unit into the dual tone mode and send single tones and have it recognize them correctly. This mode is more prone to errors however. The best way to make this work is to make certain that no tones are sent for 40ms after the first function tone is sent so that a no tone can be decoded. If the 2175 hold tone, or other audio is present, the DSP-223 will attempt to decode this as the second half of the dual function tone. The DSP-223 will also error beep back to the console if it was unable to decode a function sequence from the console. This consists of a short sequence of 3-4 beeps. Selecting single or dual function tone mode will set the number of function tones that can be programmed by scrolling in the data entry table between 16 and 100 respectively. 4.2.2.2 CTCSS Tone Two options are provided to set the CTCSS operation. PTT Only sets the CTCSS generator active during PTT detection only. Always On sets the CTCSS tone generator active at all times regardless of the PTT status. 4.2.2.3 PTT Options The PTT Options Section configures the DSP-223 while PTT is active. These options control the PTT relay, R1 and R2 relays with respect to PTT, the received console PTT frequency as well as the PTT mode. PTT Frequency selects the Hold tone frequency received from the console. The selectable frequencies are: 2100 Hz 2325 Hz 2155 Hz 2600 Hz 2175 Hz 2800 Hz 2300 Hz 2970 Hz Tone Remote 9 The Repeater Mode introduces a 400ms audio delay in the transmit path and removes the Hold tone notch filter. If the unit detects a valid Guard-Function sequence, it will key up the DSP-223 immediately. With the 400ms delay, the Guard Function is repeated out the radio interface. If the DSP-223 detects the Hold tone, it will remain keyed up allowing one radio to serve as the link to another DSP-223. PTT Tone Only causes the DSP-223 to not respond to a function tone and key up on detection of a valid Hold tone. This will eliminate all options that are function tone based, but allows the DSP-223 to be used in a most basic manner. This mode is useful for alignment when only a single tone generator is available and not a tone remote console Revert to R1 energizes relay R1 at the end of a PTT sequence. It will either latch it on or energize it for the time programmed for R1 in the function tone table. For example, if F1 uses R1 and has a timer setting of zero, the Revert to R1 option will latch the R1 relay at the end of the PTT sequence. If F1 has R1 selected and has a timer value set for R1, then at the end of the PTT, R1 will latch on for the timer value and then turn off. Note that all function tones that utilize R1 must have the same timer value setting. The setup software enforces this by changing all values for R1 when one is changed. The operation of auxiliary relays R1 and R2 as a function of PTT is selectable. When selected, R1 or R2 will close at the same time as the PTT relay. Connection to the relay contacts may be made through the DB25 connector on the rear panel. No auxiliary relay operation may also be selected. 4.2.2.4 Monitor Relay Options The MONITOR function provided in the DSP-223 decodes the valid tone sequence and provides a relaycontact closure to turn off the sub-audible-tone-decoder circuit in the radio receiver, allowing the console operator to monitor the channel for other users before transmitting (required by FCC regulations on stations equipped with continuous-tone-coded-squelch signaling). Connection to the monitor relay contacts is provided through the DB25 connector on the rear panel. On single-user stations not equipped with sub-audible signaling, or where the CTCSS decoders are disabled, the monitor function relay output may be used for any purpose such as interrogation of a status-reporting system at the station site. The monitor function may be programmed to operate in one of three modes. The DSP-223 provides three options for the MONITOR relay action. Reset on PTT resets the monitor relay when PTT goes active. Always Except PTT latches the MON relay at all times except when PTT is active, whether the monitor function tone is received or not. Momentary sets the monitor relay for a programmed period of time. 4.2.2.5 EE/Error Beeps (Rev 2.0 or higher) The DSP223 will display “EE” on the front panel LED display and transmit error beeps to the dispatch console when an un-decodable signal is received on the line RX. To defeat the error beep feature uncheck the checkbox. 4.2.2.6 Line DTMF Decoder When checked, the DSP-223 will not respond to DTMF tones sent by the console. 4.2.2.7 Audio Loop Back When checked, the DSP-223 will route all audio received at the Line RX terminals back to the Line TX terminals. In addition all functions continue to work within the DSP-223. This allows for a number of consoles to be bridged together and still monitor traffic of consoles on separate bridge segments. This function is typically used in 4-wire systems only. 10 Vega DSP-223 4.2.2.8 Individual Function Tone Setup The middle grid area of the main screen menu is used to set the actions of the DSP-223 when a particular function tone is received. The left most column is the function tone number. If the Function Tone Mode is set to single function tone, tones F1-F16 may be programmed. If the Function Tone Mode is for dual function tone, tones F00-F99 may be programmed. 4.2.2.8.1 Tone Active The Tone Active column allows the user to lockout a function tone in the DSP223. When a box is checked, the DSP-223 will respond to the selected function tones and operate as programmed. 4.2.2.8.2 Relay The Relay column allows the user to select a relay closure to be associated with a particular function tone. Selectable options are R01, R02, or no relay. Clicking the drop down list and selecting the desired relay will program the relay be closed immediately upon receipt of the function tone. NOTE: R01 = F1 and R02 = F2 with reference to the schematic. 4.2.2.8.3 Relay Group The Relay Group allows the relays to be grouped into separate functions. This sets more than one relay to be energized at any particular time by assigning separate groups. For example, if F1 has R1 selected as its relay, and F2 has R2 selected as its relay, setting the two Relay Group numbers to the same value will result in: when F1 is received R1 turns on and R2 turns off. In this scenario, F1 and F2’s relays are interlocked. If F1 and F2 have different assigned relay groups, receiving F1 does not turn off R2. Further, if a function tone has no relay selected, but has a relay group assigned that is used by another relay group, when that function is received, all relays in that group will be turned off. This allows R1 and R2 to be assigned to different groups and use other function tones with the same relay group to turn them off. 4.2.2.8.4 Relay Duration The Relay Duration sets the relay closure time. When a function tone is received, the relay closes. After the time expires, the relay will open. The timer entry is in milli seconds (i.e. 1000 mSec = 1 second). Setting the relay duration to 0 latches the relay on when the function tone is received. CAUTION: two function tones with the same relay assigned cannot have the relay close for different durations. Therefore, if the user selects R1 for F1 and F6 and set the duration for F1 to 2000ms, the F6 relay duration entry will automatically be set to 2000ms by the application software. Tone Remote 11 4.2.2.8.5 Digital Output Each function tone may be assigned a digital output. Valid entries are 0 – 64 that control the outputs labeled DIG0-DIG5. This is a binary output corresponding to the value entered. The table below shows the values and the resulting DIG0-DIG5 outputs. An entry of 64 will cause the digital outputs to REMAIN SET at the current value and not change. VALUE 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 D5 L L L L L L L L L L L L L L L L L L L L L L L L L L L L L L L L D4 L L L L L L L L L L L L L L L L H H H H H H H H H H H H H H H H D3 L L L L L L L L H H H H H H H H L L L L L L L L H H H H H H H H D2 L L L L H H H H L L L L H H H H L L L L H H H H L L L L H H H H D1 L L H H L L H H L L H H L L H H L L H H L L H H L L H H L L H H 64 D0 L H L H L H L H L H L H L H L H L H L H L H L H L H L H L H L H VALUE D5 D4 H L 32 H L 33 H L 34 H L 35 H L 36 H L 37 H L 38 H L 39 H L 40 H L 41 H L 42 H L 43 H L 44 H L 45 H L 46 H L 47 H H 48 H H 49 H H 50 H H 51 H H 52 H H 53 H H 54 H H 55 H H 56 H H 57 H H 58 H H 59 H H 60 H H 61 H H 62 H H 63 No Change D3 L L L L L L L L H H H H H H H H L L L L L L L L H H H H H H H H D2 L L L L H H H H L L L L H H H H L L L L H H H H L L L L H H H H D1 L L H H L L H H L L H H L L H H L L H H L L H H L L H H L L H H D0 L H L H L H L H L H L H L H L H L H L H L H L H L H L H L H L H Figure 6 Digital Output Chart NOTE: Digital output bits D4 or D5 are not active if DIG4 or DIG5 are enabled 4.2.2.8.6 CTCSS Frequency and Default This value allows the user to set the CTCSS frequency for a given function tone. When the function tone is received, the CTCSS tone generator frequency is set to the value corresponding to the number entered. An entry of 0 corresponds to no tone. If the Use Default CTCSS checkbox to the right of the CTCSS Frequency box is checked (see Figure 4), the value in the CTCSS tone box is ignored and the last selected value is generated during PTT. For example, F1 is used for all transmissions and the default CTCSS box is checked for F1. F2-F8 has different CTCSS values programmed for them without 12 Vega DSP-223 the CTCSS default box checked. Selecting F2 and then keying up on F1 will set the CTCSS tone to the value in the F2 row. Selecting F4 would set the CTCSS tone in the F4 row. When PTT is pressed, F1 is the default frequency and the F4 CTCSS tone is sent. Some consoles, such as the Vega C-1610 and 6124 have a paired mode that makes this operation very simple. The CTCSS tone lookup table appears below. Tone # 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 Freq.

Enable Dig4 as COR Input must be checked to enable the feature. Active High sets the polarity of the active logic signal. If checked, the radio RX will be muted when an active high is present and not muted when low. The subset feature to polarity is the R1 and R2 check boxes. When one of these boxes is checked, that relay will close with the active state setting. The relay will also close from other programmed features. If RX Mute is in an active state when changing the programming to OFF, power to the DSP223 will have to be cycled to reset the RX audio path. Figure 8 Digital 4 Setup Screen The fourth checkbox will force the DSP223 to revert to F1 programming after the entered time expires if no PTT or a COR logic changes occur. NOTE: Digital output bits D4 or D5 are not active if DIG4 or DIG5 are enabled Tone Remote 13 4.2.2.9 DIG5 Setup Button 4.2.2.9.1 Voter/Ring Down Tone Generation This grouping allows the DSP-223 to generate a user-defined tone on the Line TX pair in the event of an active logic signal on Pin 2 of the line connector or Pin-23 (DIG5) of the DB25 connector. Enable Tone on Dig5 Input must be checked to enable the feature. Active High sets the polarity of the active logic signal. If checked, the programmed tone will be generated when an active high is present and no tone will be generated when low. The subset feature to polarity is the R1 and R2 check boxes. When one of these boxes is checked that relay will close with the active state setting. The relay will also close from other programmed features. The Tone Frequency and Level boxes specify the frequency and the amplitude of the tone to be summed with receive audio. Entries of 300-3000Hz are valid. Typically a –20dBm signal is used. Some experimentation with this value may be required to get the proper performance. Figure 9 Digital 5 Setup Screen Tone On/OFF Time sets the duty cycle of the tone to create “alarm beeps” generated when DIG5 is active. Entries of 0 to 65000ms (65000ms = 65 seconds) are the allowed programmable times. An entry of zero (0) into the field generates a continuous tone. NOTE: Digital output bits D4 or D5 are not active if DIG4 or DIG5 are enabled 4.2.2.10 Set Gains Button Figure 10 at the right shows the Gain Set dialog box. A number of gains can be controlled with this setup application. This is not a replacement to tuning the unit correctly with the potentiometers, but a supplement to allow fine-tuning of the DSP-223 operation. The Handset Sidetone Gain allows the volume of the handset speaker to be adjusted by +/- 10 dB. The Radio TX Gain allows adjustment of the amplitude of the audio sent to the radio by +/- 10dB. The Line TX Gain is used to adjust the Line TX by +/- 10dB. The CTCSS Gain allows adjustment of the CTCSS tone level by +/- 10dB. Figure 10 Gain Settings 14 Vega DSP-223 4.2.2.11 Morse Code Station Identifier Setup The Morse Code configures the DSP-223 to automatically send a Morse code signal at specified times or actions. The Auto Transmit Options section of the dialog box sets the automatic transmit operation. The End of Each PTT will send the programmed Morse code string at the end of each PTT sequence. The DSP-223 waits for the end of the hold tone and then extends the PTT time to send the Monitor Morse Relay code sequence. The Timer Interval option sets the DSP99-digit display 223 to transmit the Morse code at specified time PTT, Monitor, and intervals. The timer begins running upon setup of this Power LED parameter either at power up or after programming. If the radio is keyed up when the timer indications expires, The F1 and Relays DSP-223 will wait for the loss of hold tone andF2 then (programmable add the Morse code sequence to the end of the to any function transmission.

This allows the configuration to be stored on a local hard Windows application disk or removable floppy disk. Two PTT modes and three monitor modes NOTE: Configuration data MUST be compatible with the current Windows® application version Eight selectable PTT frequencies from DSP-223 4.2.2.13 Send and Receive Configuration The Send to 223 and Recv from 223 buttons are used to transfer configuration data between the DSP223 and the PC. The serial port of the DSP-223 and the PC must be connected using the provided serial cable. When all of the configuration information has been entered into the Windows® application, the data may be sent to the DSP-223 by pressing the Send to 223 button. The Recv from 223 button will retrieve the configuration data from the DSP-223 and display the information in the Windows® application. The user may then wish to save the data to a PC (refer to section 4.2.2.12). If the data is transferred correctly the left decimal point will light for a few seconds and then turn off. If an error occurs, “EE” will appear in the display. The previously saved operation parameters will be restored. Tone Remote 15 4.2.2.14 Radio TX Audio Filters The TX Filters button sets the options for controlling the radio TX audio. 4.2.2.14.1 AGC The AGC checkbox adds an Automatic Gain Control or audio compression to the radio TX audio. AGC will help to increase the level of low audio, and decrease the level of loud audio, resulting in a more consistent level being transmitted. 4.2.2.14.2 Add CTCSS to TX Figure 12 TX Audio Parameters Screen When checked, Add CTCSS to TX will add the selected CTCSS tone to the TX audio stream. The CTCSS output (pin 11 of the DB25 connector) continues to be active. This allows CTCSS to be sent on radios that don’t have separate input pin for its injection into the audio stream. The user will need to make certain that no high pass filter is in place in the radio to cut off the CTCSS audio. 4.2.2.14.3 Pre-Emphasize Audio The Pre-Emphasis Audio option will add a pre-emphasis zero and pole into the radio TX audio stream.

The standard activation sequence that precedes each command is DTMF *0#. A 2 second timer is started upon entry of the first character of the string. If the entire control string is not entered within that timeout period, the digits are discarded and the user must re-enter the string. For routines that adjust gains, the value is adjusted and saved to the non-volatile memory. *0#1 : Increase Radio TX Gain Sending this command will increase the Radio TX gain by 1dB. Multiple repetitions of this sequence will increase the Radio TX Gain up to +10dB. *0#2 : Decrease Radio TX Gain Sending this command will decrease the Radio TX gain by 1dB. Multiple repetitions of this sequence will decrease the Radio TX Gain down to -10dB. *0#3 : Increase Line TX Gain Sending this command will increase the Line TX gain by 1dB. Multiple repetitions of this sequence will increase the Line TX Gain up to +10dB. *0#4 : Decrease Line TX Gain Sending this command will decrease the Line TX gain by 1dB. Multiple repetitions of this sequence will decrease the Line TX Gain down to -10dB. *0#5 : Increase CTCSS Gain Sending this command will increase the CTCSS gain by 1dB. Multiple repetitions of this sequence will increase the CTCSS Gain up to +10dB. *0#6 : Decrease CTCSS Gain Sending this command will decrease the CTCSS gain by 1dB. Multiple repetitions of this sequence will decrease the CTCSS Gain down to -10dB. *0#7 : Loopback Line RX to Line TX This command will place the DSP-223 into the Loopback Mode. Audio received at the RX terminals of the Line interface on the DSP-223 will be echoed back onto the TX terminals. This mode lasts for approximately 15 seconds and then the DSP-223 reverts back to its normal operation. *0#8 : Send 1kHz Tone to both Radio and Line Interfaces This command will generate a 1kHz, 10dBm, tone on both the Radio and Line TX terminals. This can be used to set the DSP-223 TX level. The tone will last for approximately 15 seconds. There are no relay closures associated with this mode. The following DTMF sequences are enabled for control of the Kenwood x150/x180 radio Refer to Section 7 – Specific Radio Control for Adaptor Kit Information *0#9 : Toggle SCAN Mode of the Kenwood x150/x180 Radio This command will toggle the SCAN mode of the Kenwood x150/x180 Series radio on and off. *0#10 : Send the last Kenwood FleetSync® ANI data This command causes the DSP-223 to generate a DTMF string to the Line TX corresponding to the last seven digit Kenwood FleetSync® ANI data received by the radio. Tone Remote 19 5 Theory of Operation The DSP-223 is a Digital Signal Processor (DSP) based product. Many of the signals that once could be probed on older products, are handled within the DSP itself. This includes DTMF decoders, notch filters, tone decoders, and all of the audio summing. Most of the gain controls are also included within the software of the DSP. Because of this, hardware is simplified at the expense of software creation time and user serviceability. The next sections discuss the portions of the DSP-223 that can be tested using a common oscilloscope and voltage meter by a qualified service technician. 5.1 DSP-223 Audio Input Paths The DSP-223 has only a single stereo Analog to Digital Converter (ADC) U25. The left channel converts the Line receive audio and the right channel converts the Radio receive audio. A CMOS switch, U2, is used to break those paths and insert handset audio for transmission down the line or to the radio. Up to the point of entry into the ADC, the audio is analog and handled by standard op-amps. These paths can be followed on the schematic and probed with any high-impedance measurement device. 5.2 DSP-223 Audio Output Paths The DSP-223 has two stereo Digital to Analog Converters (DACs), U3 and U4. U4’s left channel drives the sidetone for the handset. U4’s right channel is used for the CTCSS tone generation. U3’s left channel is the line transmit audio source and the right channel of U3 is the radios transmit audio source. Once the analog signal has been reconstructed on U3 and U4, they can be measured by conventional techniques. 5.3 Troubleshooting Aid Problem What is position “A” on a jumper plug The DSP223 will not decode The DSP223 will not PTT radio Radio TX audio is low or distorted EE and error beeps occur Radio RX audio is low or distorted Possible Solution On early PCB’s the “A” position of the jumper is the double line side of the silkscreen around the jumper plug. Is the power LED on the front panel ON? Is J11 in the “A” position? If in 4-wire, make sure the console TX is connected to the DSP223 line RX.

Download required files from web site www.vega-signaling.com and follow Section 6 of the manual to update DSP223 software. Check our web site for updated Troubleshooting aids. 6 Loading the DSP-223 Operational Software 1) The latest DSP-223 operating software and Windows® application software (and all previous versions) may be downloaded from www.vega-signaling.com/dspsoftware.htm 2) Copy all included files into a directory on your PC, if they are zipped, extract them into this directory 3) From the Start->Run, or Windows Explorer, menu run the file “winmon.exe”. This file needs to be run only one time on a particular PC. It registers the drivers to communicate with the Vega products 4) Either on the desktop or from the taskbar editor, add a shortcut to the program “Flashmon.exe”. Alternately it can be run from the Start->Run menu as well. The dialog box contains a few options that can be used. 5) The first step is to put the DSP-223 into programming mode. This is done by first removing power from the unit. 6) The upper left corner of the Flashmon dialog box has a pull down menu for setting the baud rate. The DSP-223 requires this value to be set to 19200. Change the baud rate to 19200. 7) With a straight through cable connected from the PCs Com1 port, (Com1 is the only option as of now) click the “Power On” button in the dialog box and then apply power to the DSP-223. 8) After a couple seconds, the message “Power is On” will appear in the message window of the dialog box. This indicates that communications has been established with the DSP-223 and that it is now ready to accept a software download. 9) Click on the “Program…” button. Find the file for the version of software to be flashed into the DSP-223. It will always have an extension of .BNM. Usually it will be of the form DSPVXX.BNM. 10) Double click or select the file and open it to begin the download process. 11) The verify button can be used the same way as the “Program…” button but it does not write to the flash, only verifies it. 7 Specific Radio Control Operating software Version 2.6 enables the DSP-223 to control the Relm BK Series and Kenwood x150/x180 Series radios with serial commands from the Digital Expansion Port. If one of these radios is connected to the DSP-223 when power is applied, the DSP-223 will detect the presence of the radio and set the operating configuration. Standard radio control operations are PTT, monitor, and channel change (i.e. F1=channel 1, F2=channel 2, etc.). Power to the DSP-223 is provided by the radios. Additional control functions for the Kenwood x150/x180 are scan on/off, FleetSync® ANI detection and EMERGENCY message receipt. The DSP-223 will generate a DTMF string corresponding to the seven digit FleetSync® ANI format on the Line TX output. A stand-alone DTMF ANI decoder (i.e. Communications Specialists Model ST-888) must be used to display the ANI information. Adaptor kits for the specific radios are available that contain all the hardware and cables required for control of the radio. Complete instructions are also included for installation and operation of the DSP-223. The adaptor kits are: • DSP-223/Relm Serial Interface Kit - P/N 0101239 • DSP-223/Kenwood x150/x180 Serial Interface Kit – P/N 301896000 Tone Remote 21 8 Pin out and Jumper Settings Quick Reference Table DB25 Pin 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 Shell = = = = = = = = = = = = = = = = = = = = = = = = = = Signal PTT N.C.
