Description of Arguments
Query only.
Returns the value of the internal temperature sensor (degrees C) in the form sxx, where:
EXAMPLE: <0/TMP? >0/TMP=+26
Query only. (1:1 set-up)
This query is sent to the online modem of a 1:1 pair. It provides access to the fault status information
(FLT?) of the offline modem. This is the only way to interrogate the status of an offline modem at the
distant-end of a link. The response format may be:
No_1for1=Indicates that no 1:1 system has been detected. Presence of a 1kHz signal from the
CRS-150 is used to indicate a 1:1 set-up;
No_Comms=Indicates that a 1kHz signal has been detected, but that there is no (or not yet) a
response for the modem;
abcdefgh00=The FLT? response information from the offline CDM-425 unit.
Query only.
Returns the current highest-priority fault and status codes for the Unit (hardware), TX Traffic, RX Traffic, and ODUs:
a=Unit status:
0=No faults
1=Power supply fault, +5 volts
2=Power supply fault , +12 volts
3=Power supply fault, -5 volts
4=Power supply fault, +3.3 volts
5=Power supply fault, -12 volts
6=Power supply fault, +2.5 volts
7=Top Card comms
8=Tx synthesizer lock
9=Rx synthesizer
A=Top card load fail
B=Reserved
C=HDLC FPGA load fail
D=CnC FPGA load fail
E=Reserved
F=Calibration data missing
G=Reference unlocked (Note: Tx off)
H=FPGA Over Temperature Alarm
I=RF Over Temperature Alarm
J=Packet Processor mailbox fault
K=Fractional CnC use only
L=Top Card 3.6 Volt fault
M=Top Card 5.5 Volt fault
N=Calibration data transfer error
