Buffer Fill
State N/A 2 bytes,
numerical
Query only.
Unit returns the value of the buffer fill state. Values
range from 1 to 99% .Example: BFS=33 (buffer fill
state is 33%) Returns 00 if demod unlocked. N/A BFS? BFS=xx (see
description for
details of
arguments)
Rx BER N/A 5 bytes Query only.
Unit returns the value of the estimated corrected BER
in the form a.b x 10exp-c. Fist and second bytes are
value, 3rd and 4th bytes are the exponent.
Returns99999 if demod is unlocked.
Example: BER=4.8E3 (BER is 4.8 x 10-3) N/A BER? BER=a.bEc
(see description
for details of
arguments)
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)
Local/Remote
Status N/A 1 byte, value of
0 or 1 Query only.
Returns the local/remote status of the unit, where:
0 = local
1= remote
Example: LRS=1 (unit is in remote mode) N/A LRS? LRS=x
(see description
for details of
arguments)
Serial Number SNO= 4 bytes
numerical Command portion is FACTORY USE ONLY. Used
to set or Query the units 4 digit serial number.
0000 to 9999 Unit returns its S/N, in the form xxxx.
Example: SNO=1765 SNO= (message ok) SNO? SNO=xxxx
(see description
for details of
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 description
for details of
arguments)
Equipment ID N/A 6 bytes,
numerical Query only.
Unit returns information concerning the equipment
identification, and the options fitted, in the form
aaaabc, where:
aaaa defines the Modem model number. Example:
0500 is CDM-500
b defines the IF band, with 1 = 70MHz, 2 = 140MHz
c defines RX only, with 1 = RX/TX, 2 = RX only
Ex: EID=050012 (CDM-500, 70 MHz band, RX
only) N/A EID? EID=aaaabc
