Redundancy
State N/A 1 byte, value of
0 or 1 Query only.
Returns the redundancy state of the unit, where:
0 = Off Line (forced into standby by 1:N or 1:1 Switch) 1= On
Line (normal). All other codes invalid. Example: RED=1 (On
Line) N/A RED? RED=x (see
description for
details of
arguments)
Equipment
ID N/A 6 bytes,
numerical
Query only.
Unit returns the equipment identification, and the options fitted,
in the form aaaabc,
where:aaaa defines the Modem model number.
2550 is CDM-550T, no Reed-Solomon or Turbo
3550 is CDM-550T with Reed-Solomon Codec
4550 is CDM-550T with Turbo Codec fitted (Rate 3/4 QPSK
only - S/W Version less than 1.15)
5550 is CDM-550T with Turbo Codec fitted (Rate 3/4 QPSK,
plus Rate 21/44 and Rate 5/16 BPSK)
6550 is CiM-550T, no Turbo
7550 is CiM-550T, with Turbo
where: b defines the IF band, with 1 = 70MHz, 2 = 140MHz
c defines RX only, with 1 = RX/TX, 2 = RX only.
Example: EID=455011 (CDM-550T, Rate 3/4 Turbo Codec, 70
MHz band, RX/TX)
N/A EID? EID=aaaabc

arguments)
Software Revision N/A 4 bytes,
numerical Query only.
Unit returns the value of internal software revision installed in
the unit, in the form x.xx
Example: SWR=1.03 (Ver 1.03) N/A SWR? SWR=x.xx (see
