DMD20/DMD20 LBST Universal Satellite Modem User Interfaces
TM103 – Rev. 2.8 4-31
RX MAJOR (menu)
FPGA CFG {Pass/Fail, Unmasked/Masked}
Indicates a receive FPGA hardware failure.
DSP CFG {Pass/Fail, Unmasked/Masked}
Indicates a receive DSP failure.
SIGNAL LOCK {Pass/Fail, Unmasked/Masked}
Indicates that the demod is unable to lock to a signal.
INPUT LVL THRESH {Pass/Fail, Unmasked/Masked}
Indicates Rx signal level has fallen below input
threshold.
FRAME LOCK {Pass/Fail, Unmasked/Masked}
Indicates that the Framing Unit is unable to find the
expected framing pattern.
MULTIFRAME LOCK {Pass/Fail, Unmasked/Masked}
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 Rx 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 Rx 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.
LNB CURRENT {Pass/Fail, Unmasked/Masked}
Indicates that the LNB current has fallen outside of the
threshold limits.
LNB VOLTAGE {Pass/Fail, Unmasked/Masked}
Indicates that the LNB voltage has fallen outside of the
threshold limits.
ETHERNET WAN Indicates that the interface card is faulted and will not
pass data (displays only when the Ethernet Card is
installed and the Ethernet Interface is selected).
FORCED ALARM {DISABLED, ENABLED}
Allows user to enable a forced Rx summary alarm.
