Response to
Query
2 bytes Command or Query.
Sets or returns the CDI-40 ASI Rx Frame Size in the form sf, where:
s=1 (Interface Slot 1 only)
f=Frame size, where 0=188 bytes, 1=204 bytes
NOTE: Not valid for Slot 1 CDI-60 HSSI or Slot 2 CDI-70 GBEI operation.
COMMAND EXAMPLE: <0001/ARF=11{CR} (sets Interface Slot 1 to 204 byte
frame size)
1 byte Command or Query.
Unit returns the redundancy auto/manual mode of the unit in the form x
where:
0=Manual
1=Automatic
COMMAND EXAMPLE: <0001/ASW=0{CR} (sets Manual switching mode)
2 bytes Command or Query.

s=1 (Interface Slot 1 only)
f=frame size, where 0=188 bytes, 1=204 bytes
NOTE: Not valid for Slot 1 CDI-60 HSSI or Slot 2 CDI-70 GBEI operation.
COMMAND EXAMPLE: <0001/ATF=11{CR} (sets Interface Slot 1 to 204 byte
frame size)
7 bytes Query only.
Returns the value of the estimated BER in the form a.bEscc, (representing ab x
-c
10 ), where:
a.b=BER value
E=exponent indicator
s= sign (+/-)
cc=exponent value.
NOTE: Unit returns 0.0E+00 if the demodulator is unlocked.
EXAMPLE: <0001/BER?{CR}
>0001/BER=4.8E-03{CR}{LF} (returns BER of 4.8 x 10
None Command only.
THIS COMMAND TAKES NO ARGUMENTS.
Forces the unit to clear the stored events log.
