F.3.2 Front Panel Menu Operations
The ODU menu allows the user to access an FSK menu that permits the CDM-600L to interface
directly with an FSK-capable BUC. The interface is accomplished using a low-speed, half-duplex
FSK link on the Tx IF port, with a carrier frequency around 650 kHz.
Configuration menus for the LNB and BUC allow the user to set up the power supply, 10 MHz
reference and low/high current alarm thresholds for the BUC and LNB, and power-up carrier output
turn-on delay for the BUC. LO menus for the BUC and LNB allow the user to set up the up-convert
and down-convert parameters for the BUC and LNB so that the TX and RX frequencies are handled
as the satellite frequencies rather than the modem IF input/output frequencies.
