2.0 POWER SUPPLY The TZM443 must be powered at 230 Vac 50Hz (115Vac 60Hz on request) with the supplied power cable. The socket of the main cable must be connected to the panel plug placed on the left hand side of the rear panel. The panel plug has a fuse carrier for 5X20 fuses. In case of fuse failure, replace it with an equivalent one, as specified at the back of the unit (T 500mA).
CAUTION All operations must be carried out by highly skilled personnel who must be informed on risks concerning electric shock.
In some nations it is necessary to change the plug in order to adapt it according to the local standard types. The code for the identification of the wires is as follows: -Brown PHASE -Blue NEUTRAL -Yellow/Green GROUND
(Marked by the letter L, it could be red) (Marked by the letter N, it could be black) (Marked by the letter E, it could be green) CAUTION Grounding is compulsory

4x4 HIGH RES. & AUDIO MATRIX
Switching is carried out by following the INPUTS - OUTPUTS sequence. Operationally: The 4 buttons with a built-in LED, called "INPUTS", are used for selecting a source. When a source is selected, it is immediately switched to the PREVIEW output. The 4 "OUTPUT" buttons are used for switching the previously selected input to the required output. If MODE AFV (Audio Follows Video) is enabled, the video and audio input signals are switched to the preview output and subsequently to the required output; if "only video" is enabled, the switching applies only to the video. This also applies to "only audio”. The status of the machine, including the preview, is shown on the LED matrix, which is installed on the unit front panel. The color of the LED indicates the type of signal on the output: -green indicates audio -red indicates video -orange indicates audio and video (AFV, namely Audio Follows Video).
5.1.1 Switching time setup from keypad: The TZM443 features the “through blank” switching mode. The switching time is useradjustable to permit the perfect matching with the destination device. This important feature prevents annoying effects coming from LCDs when switching a signal to their input. Since every LCD has its own response time, the user can change the through blank duration from 0.3 to 2 seconds to achieve optimal switching. There are four settable times: IN key LED Switching time 0.3 sec.; 0.5 sec.; 1 sec. and 2 sec. (In LOCK MODE) In order to display and setup the through blank IN 1 300 msec switching time with the keypad, the MODE button IN 2 500 msec must be in LOCK position. IN 3 1 sec. By doing so, the setup time will be displayed on IN 4 2 sec. the LEDs of the keys associated with inputs 1, 2, 3, and 4 with the following meaning: To set up a new switching time, it is necessary to hold down the required key for 2 seconds according to the time required. The default value is 500 msec.

The switching time setup, performed through the keyboard, is valid for all outputs of the matrix, including the preview output; whereas it is possible to set up a different time for every single output via a command from the serial line. In this case, the set time for output No. 1 will be displayed on the LEDs. The display of the connections on the LED matrix will follow the actual switching on the outputs; afterwards, the display of a switching command will be delayed for a period of time equal to the switching time. PLEASE NOTE Remember that switchings resulting from a RECALL command do not occur "through blank"
5.2 Keypad Setups By pressing a combination of keys, different commands and setups are possible for the TZM443 unit. In addition, it is possible to store 3 machine status presets and to recall them at a subsequent time. It is also possible to store a default configuration so that the machine will start up with a particular setup. Button Mode+Input1 Mode+Input2 Mode+Input3
Function Save status 1 Save status 2 Save status 3
Button Mode+Output1 Mode+Output2 Mode+Output3
Function Recall status 1 Recall status 2 Recall status 3
The 3 presets mentioned above are part of the 8 that can be recalled from the PC (as explained in paragraphs 7.6 and 7.7). Thus, we will have the possibility to save and recall: 3 configurations from the keypad 4 configurations from the IR remote control 8 configurations from the PC PLEASE NOTE Recalling a keypad preset, from the computer or from the remote control, also sets up the same configuration as a restart Mode for 2 sec.
Machine status storage (one flash of the two MODE button LEDs indicates that the information has been stored). When started up again, the TZM443 will set up with the same status.
Subsequent preset recalls from the keypad or computer will change the default configuration, thereby corresponding to the last recalled preset. ELPRO Video Labs s.r.l.

8.0 CONTROL FROM COMPUTER VIA RS485 A software in Windows, available on Elpro’s website www.elprovideolabs.com, is able to control the TZM443 via RS232 or RS485 If the user wants to develop his own customized software, the same website offers protocols to be implemented both for RS232 and RS485. All functions of the TZM443 matrix can be controlled by sending or receiving hexadecimal or ASCII character strings via a computer. The transmission protocol is of the multipoint master/slave type: the TZM443s are the slave machines, whereas the host which controls them is the master machine. Up to 8 TZM443 units, identified by addresses 0 – 7, can be connected to the 485 Bus. The serial connection features are: 8 data bits, no parity, 1 stop bit speed that can be set at 2400 or 9600 bauds, The transmission speed, the address of the unit and the response time can be set via a special control from the RS232. The TZM443 response time is the time that should pass between the end of the reception of the command and the beginning of the transmission of the response. Such time allows the host to release the 485 bus and to get ready for the reception without causing conflicts. the following parameter defaults are automatically applied: - speed - unit address - response time
= 9600 bit/sec = 0 (30 hex) = 32 ms
Wait 150msec between one command and the other.

The protocol used requires all messages exchanged between the host and TZM443 to be between the following command characters: - commands from host to TZM443: STX ADDR command ETX - response of the TZM443 to host: STX ADDR response ETX The character STX corresponds to 02 hex, The character ETX corresponds to 03 hex, the field ADDR is the address of the TZM443: from 30 hex to 37 hex (namely from 0 to 7 in ASCII) The contents of the fields command and response are the same as the commands previously indicated for protocol RS232 with the exception of character CR (hex 0D) which, in this case, is skipped. 8.1 Managed Commands The commands which are possible to send via RS485 are all those required for the RS232 with the exception of the command “Set RS485 communication parameters”: - video and audio switching commands. - video switching command. - audio switching command. - status request - creating a preset - recall of a preset - firmware release identification request. - global mode request - set through blank switching time - through blank switching time request - set preview output - mute setup on preview output Example: In this case, the video switching control will have the following format: STX ADDR VXXYY ETX where: V is the character Hex 56 XX is the output (from 01 to 4) YY is the video input (from 01 to 4) The TZM443 matrix will respond: STX ADDR ACK ETX where: ACK is the character Hex 06 if the control has been executed correctly STX ADDR NACK ETX where: NAK is the character Hex 15 if it has found incorrect transmission or parameter errors. Hence, the switching control of video input 2 on bus 4 for the TZM443 with address 2 will be as follows: STX 2 V 04 02 ETX (in code Hex: 02 32 56 30 34 30 32 03) The matrix will respond with: STX 2 ACK ETX (in code Hex: 02 32 06 03) or with: STX 2 NACK ETX (in code Hex: 02 32 15 03)
