The cassette has two digital SAT IF inputs and an HF output.
2.5 Software query Control unit If necessary, you can activate the indication of the software version of the control unit manually: • Press any two keys on the control unit of the head-end station simultaneously until the display goes dark and the software version, e.g. “V 37” appears. 3 Assembly 3.1 Installing the cassette Caution – Ensure the head-end station is mounted so it will not be able to vibrate.
3.2 Installing the F terminals To comply with the current EMC regulations, it is necessary to connect the lines leading in and out of the head-end station using F terminals. When mounting the cassette in an STR 19-8 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 F terminals. • Insert the required number of F terminals in the openings provided in the head-end station or in the 19" cabinet.
Notes: 3 Slot for CA module 4 Eject button for CA module 5 Socket “RS 232” The operating software of the cassette can be updated via the 9-Pin D-DUB 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.tv”. 3.4 Retrofitting a CA module The cassette is equipped with a common interface. It allows you to connect a CA module for various encryption systems and service providers.
