Page 9: Installation
Installation Installing the cassette Pull the mains plug of the head end station out of the mains socket before inserting or replacing any cassettes. • Remove the fastening screws of an unoccupied slot from the bracket of the head end 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. -
Page 10: Connecting The Cassette
Connecting the cassette To comply with the current EMC regulations, it is necessary to connect the lines leading in and out of the head end station (e.g. cinch, HF) using cable termi- nals. When mounting the cassette in a head end station which is installed in a 19" cabinet, make sure that the connections leading in and out (e.g. -

Page 12: Programming
Programming The following examples show how the PEDQ 4005 QMX cassette is programmed; the output channels can be set from S21 to S41. The other cassettes that are listed are set in the same way. Preparation Notes: – In the "LEVEL" menu item, the cassette generates an equally powerful HF carrier on the video carrier frequency of the channel. In this way, the cas- sette's level can also be set using an analogue TV test receiver that is set to the video carrier frequency of the channel. -

Page 19: Adapting The Output Level
Adapting the output level This setting is not essential for these cassettes. Under this menu item, the "control" setting is used to set a digital carrier to the analogue video carrier frequency of the output channel. This makes it possible to measure the absolute output level of these cassettes with an analogue test receiver. -

Page 22: Setting The Station Filter
Setting the station filter – If no channel-related input signal is found, "FILTER: no Service" appears in the display. In this case, check the configuration of the system. – Every input signal that is added via channel strip "A", "B", "C" or "D" in- creases the output symbol rate. If you add too many complex signals to the new data stream, the symbol rate rises to above 100%. This can result in interference to the transmission of the video and audio signals. -

If the station filters are activated, this value will be less than the value of "number 1". The value will fluctuate, as the data rate depends on the supplied signals. • Use to position the cursor under the digit to be set for "number 1", then use to set the symbol rate. -
