regulations and notes
• Assembly, installation and servicing should be carried out by authorised electricians. • Switch off the operating voltage of the system before beginning with assembly or service work or pull out the mains plug. • Do not perform installation and service work during thunderstorms. • Install the system so it will not be able to vibrate… - in a dust-free, dry environment - in such a manner that it is protected from moisture, fumes, splashing water and dampness - somewhere protected from direct sunlight - not within the immediate vicinity of heat sources - in an ambient temperature of 0 °C to +50 °C. In case of the formation of condensation wait until the system is completely dried. • Ensure that the head-end station is adequately ventilated. Do not cover the ventilation slots. • Beware of short circuits • No liability is accepted for any damage caused by faulty connections or inappropriate handling. • Observe the relevant standards, regulations and guidelines on the installation and operation of antenna systems. • The standards IEC/EN/DIN EN 50083 resp. IEC/EN/DIN EN 60728 must be observed. • For further information please read the assembly instructions for the headend station used. • Test the software versions of the head-end station and the cassette and update them if necessary. The current software versions can be found at "www.gss.de". Take action to prevent static discharge when working on the device! Electronic devices should never be disposed of in the household rubbish. In accordance with directive 2002/96/EC of the European Parliament and the European Council from January 27, 2003 which addresses old electronic and electrical devices, such devices must be disposed of at a designated collection facility. At the end of its service life, please take your device to one of these public collection facilities for proper disposal.

2.4 D e s c r i p t i o n
The monitoring cassette PSCU 6000, in the following called cassette, is used to provide the output levels and the output data of the head-end stations monitored via an info channel in the cable network. The info channel is programmable in the range of C21 … C69. The following parameters are controlled: – Analog TV channels: HF level and synchronization pulse. – Digital TV channels: HF level, BER (Bit Error Rate). – Radio stations: HF level, RDS identifier
The info channel contains the channels of the cable network set, the appropriate channel names (identified from the RDS resp. VPS data), the bit error rate (BER) and the output level of the respective channels. In addition the signals fed via the audio and video sockets can be transmitted via the info channel or the data of the info channel can be provided as audio and video signals.
Is the cassette connected to a corresponding management unit via the "RS-232" socket, error messages can be sent via phone, in form of e-mail or SNMP inform requests, if any pre-stored reference level is exceeded. Therefore the configuration is to be done with the help of a PC and the PSW 1000 software. For this observe the operation instruction of the PSW 1000 software, to be downloaded from our home page "www.gss.de".
To operate this cassette the software version of the control unit must be "V 44" or higher. You can find the current operating software for the control unit and the cassette, the software "BE-Flash" and the current assembly instructions on the website "www.gss.de".
The cassette is intended for use in the PROFI-LINE head-end stations.

The signal paths are adjustable via jumpers.
Note Take action to prevent static discharge when working on the device. Danger of cut injuries! The cassette is made of punched stainless steel parts. Some of them may have sharp edges.
• Screw 3 screws S (TORX TX6) out of the cassette cover. • Push the cassette cover to the rear and remove it.

the cassette
– Ensure the head-end station is mounted so it will not be able to vibrate. Avoid, for example, mounting the head-end station onto a lift shaft or any other wall or floor construction that vibrates in a similar way. – Before installing or changing a cassette unplug the power cable from the mains power socket. – To ensure a higher measurement accuracy, heating up of the cassette should be kept as low as possible. Therefore we recommend to fit the cassette into the first slot of the head-end station. • Remove the fastening screws 1 of the first slot from the bracket of the headend station. • Insert the cassette in this slot and push it into the housing. • Align the cassette and apply slight pressure to connect it to the connections of the board and the HF bus bar. • Fasten the cassette with the screws 1.

3.3 EMC
KLASSE
CLASS
r e g u l at i o n s
To comply with the current EMC regulations, it is necessary to connect the lines leading in and out of the head-end station using cable terminals. When mounting the cassette in a head-end station which is installed in a 19" cabinet, make sure the connections leading in and out for the 19" cabinet are made using cable terminals. The attenuation of shielding of the connection lines for ASI and antenna must meet the requirements for "Class A".
• Insert the required number of cable terminals in the openings provided in the head-end station or in the 19" cabinet. Tighten the nuts on the cable terminals until the teeth on the lock washer have penetrated the exterior coating and a good connection is made between the housing and cable terminals.

• Connect the "MEASURING OUTPUT" of the cassette to a test receiver, if necessary. • Connect the "MEASURING INPUT" of the cassette to the measuring output of the head-end station system. The input level of the cassette is not allowed to exceed 80 dBµV. If necessary, set the input level using a commercially available pluggable level control. • Connect the "VIDEO" and "AUDIO" sockets to the required peripheral device dependent on the positioning of the jumpers (see page 9). • "RS 232" socket
—> The operating software of the cassette can be updated via the 9-pin D-SUB socket "RS-232" using a PC or notebook and the software "BE-Flash". You can find the current operating software on the website "www.gss.de".

—> To transmit alarm messages, we recommend to connect the cassette to a corresponding management unit via the "RS 232" socket. Additionally the cassette can be configured using a PC or laptop and the PSW 1000 software.
• The "START/SEARCH" button starts the channel search of the cassette (see chapter 6, page 22). —> During the search function, the operation display "LED" is flashing.
• Via the "DC IN" socket the cassette additionally can be supplied with operating voltage using a commercially available power supply. (10 … 40 V, max. 700 mA). This ensures the control function of the system even if the internal power supply fails to operate. • Connect the head-end station to the mains power supply.

search)
To ensure a high measurement accuracy for the channel search, the cassette must be in operation for about 30 minutes.
• Connect a TV set or a test receiver to the measuring output of the cassette or to the HF output of the head-end station and tune it to the channel set (in the programming example "C21"). • To create the info display press the "START/SEARCH" button (see page 13) for approx. 10 seconds
—> During the search function, the operation display "LED" is flashing. The search function can take up to 10 minutes. The channel search starts with the analog TV channels in ascending channel order: C2 … C4, S2 … S10, C5 … C12, S11 … S41 and C21 … C69. As criteria for the analog TV channels, the synchronization pulse and the HF level are used. The station name is determined via the VPS identification signal. The HF level is measured and stored as reference value for the control function. For analog TV channels without VPS identification signal, blanks are entered as station name.

When the search for analog channels is completed, QAM channels in the frequency range of 306.00 MHz to 858.00 MHz are searched in steps of 8 MHz. The criteria for QAM channels are the signal level and the fact that the tuner "locks" on one of the different modulation modes and symbol rates. The centre channel frequency, the symbol rate, the bit error rate (BER) and the signal level are measured and stored as reference values for the control function.

The search finally explores the frequency range of 87.5 MHz to 108 MHz in steps of 50 kHz for FM radio stations. The HF level is used as criterium for FM radio stations. If a radio station is found, it is tried to determine the station name via the RDS data. The HF level is measured and stored as reference value for the control function. For FM stations without RDS identification signal, blanks are entered as station name.
