Configuration menus allow the user to set up power supplies, a 10 MHz reference and low/high
current alarm thresholds for the BUC and LNB. 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 user can
view the satellite frequencies as well as the modem IF input/output frequencies.
BUCs, CSAT and KST transceivers may be controlled and monitored via an FSK link.
