If fitted with the P315 BUC DC supply option, then the modem
may source 100W of 24V or 180W 48V (factory option) to the BUC `up
the coax` or `line powered`. The only option available here is
or
CAUTION: Needless to say severe damage may occur if a DC supply is fed to a
BUC not configured for being `Line powered`.
The internal 10MHz reference may similarly be sourced from the modem `up the
coax` to the BUC. The only option available here again is
If the modem is sourcing the DC supply to the BUC, then it may be set to
monitor the current drawn by the BUC, and to raise an alarm (Tx Fault) if it goes
outside a user defined window. Two subsequent screens allow the user to
independently set the low and high current alarm thresholds. The current being
drawn by the BUC can be monitored from the

This screen is available on both 70MHz/140MHz P300 modems and P310 L-Band modems, and
allows the modem to be set to display and edit the final SHF frequencies instead of the IF
frequencies. When the BUC Type has been set to a known Paradise BUC and the modem has the
FSK communications option then this setting is done automatically and the menu option to manually
set the frequency shift is not presented.
