(Instruction &
Qualifier)
Response to Query
Rx Signal
Level
N/A 5 bytes Query only.
Returns value of Rx signal level, in dBm, in the form xxxxx, where:
xxxxx = value from -20 to -90 dBm.
If >-20dBm, returns RSL = GT-20 (GT = ‘greater than’)
If <-90 dBm, returns RSL = LT-90 (LT = ‘less than’)
If <-20 and >-90 returns RSL = EQ-XX (EQ = ‘equal to’)
EXAMPLE: <0/RSL=EQ-45 (indicating -45 dBm)
N/A RSL? RSL=xxxxx
(see description
of arguments)
Rx Frequency
Offset
N/A 6 bytes Query only.
Returns value of measured frequency offset of the carrier being demodulated, in the form sxxx.x, where:
s = sign (+ or -)
xxx.x = value from 0 to 200 kHz, in 100 Hz steps.
Returns 999999 if the demodulator is unlocked.
EXAMPLE: <0/RFO=+002.3 (selects + 2.3 kHz)
N/A RFO? RFO=sxxx.x
(see description
of arguments)
Temperature N/A 3 bytes Query only.
Returns the highest of 4 temperature sensors. Value of the internal temperature sensor, in the form xxx,
where:
xxx = degrees C
EXAMPLE: <0/TMP=+26
N/A TMP? TMP=xxx
(see Description of
Arguments)
Faults and
Status
N/A 9 bytes Query only.
Returns the current highest-priority fault and status codes for the Unit (hardware), TX Traffic, RX Traffic, and
ODUs in the form aaaaaaaabbbbbbbbccccccccdexx, where:
aaaaaaaa = Unit status:
00000000 = No faults

08000000 = Main Board Power Supply 1.9V
04000000 = Main Board Power Supply 2.5V
02000000 = Main Board Power Supply 1.25V
01000000 = Modem Board Power Supply 5.5V
00800000 = Modem Board Power Supply 3.8V
00400000 = Modem Board Power Supply 2.8V
00200000 = Modem Board Power Supply 3.3V
00100000 = Modem Board Power Supply 1.8V
00080000 = Modem Board Power Supply 1.2V
00040000 = Tx Power Cal
00020000 = FPGA Load Fail
00010000 = Reference Unlocked
00008000 = Temperature Exceeded
00004000 = Unit Fault
00002000 = PIIC1 External Clock Activity
00001000 = PIIC1 External Clock In Range
N/A FLT? FLT=aaaaaaaabbbb
