DMD50 Universal Satellite Modem User Interfaces
TM118 – Rev. 1.1 4-23
-12V SUPPLY Displays the measured voltage of the -12 Volt power bus
located inside the modem.
RX BUFFER LEVEL {0 – 100%}
Displays the status of the Doppler Buffer.
RX BUFFER RESET ((ENTER)) Allows the user to re-center the Doppler Buffer when
<ENTER> is pressed on the keypad.

Edit Table
FPGA CFG {Pass/Fail, Unmasked/Masked}
Indicates a transmit FPGA configuration failure.
DSP CFG {Pass/Fail, Unmasked/Masked}
Indicates a transmit DSP configuration failure.
SCT CLOCK PLL {Pass/Fail, Unmasked/Masked}
Indicates that the Tx SCT Clock PLL is not locked. This
alarm will flash on during certain modem parameter
changes. A solid indication points toward a configuration
failure within the modem.
SYM CLOCK PLL {Pass/Fail, Unmasked/Masked}
Indicates that the Tx Symbol Clock PLL is not locked.
This alarm will flash on during certain modem parameter
changes. A solid indication points toward a problem with
the incoming clock to the modem (SCTE).
LB SYNTH PLL {Pass/Fail, Unmasked/Masked}
Indicates that the Tx L-Band Synthesizer is not locked.
This alarm will flash on during certain modem parameter
changes. A solid indication points toward a configuration
problem within the modem.
IF SYNTH PLL {Pass/Fail, Unmasked/Masked}
Indicates that the Tx IF Synthesizer is not locked. This
alarm will flash on during certain modem parameter
changes. A solid indication points toward a configuration
problem within the modem.
ETHERNET WAN {Pass/Fail, Unmasked/Masked}
