Arguments for
Command or
Response to
Query
Query only.
Valid only in CDM-570A Compatible Mode (CMO=1).
Returns the value of the average BER in the form x.xxEsyyl, where:
First 8 bytes are the value.
Last byte is the indicator of Sync Loss. A '*' in last byte means there was a loss
of pattern synchronization since last restart, but now is synchronized. A '_'
(space) in last byte means pattern synchronization is achieved.
Returns 999999999 if there's no sync in BERT monitor.
Examples: <0/BRR?
1) >0/BRR=2.80E-07 (BER is 2.80 x 10
2) >/BRR=3.40E-05* (BER is 3.40 x 10
Command or Query.
Valid only in CDM-570A Compatible Mode (CMO=1).
Sets or returns ACM operating parameters in the form mMAT, where:
VersaFEC ACM (IP-ACM):
m=Minimum ModCod, range is 0 to 9, and A (for ModCod=10) or B (for
ModCod=11)
M= Minimum ModCod, range is 0 to 9, and A (for ModCod=10)or B (for
ModCod=11)
A= Defines action on remote demod unlock
0 = go to minimum Tx ModCod
1 = maintain Tx ModCod
T=Target Eb/No Margin, from 0 to 9 that is two times the Eb/No in dB (from
0.0dB to 4.5dB).
VersaFEC-2 ACM (V2-ACM):
mM=Maximum Tx ModCod in decimal, range is 00-37 for Long block, and
00-35 for Short Block.
A=Action on remote demod unlock (0=go to Tx ModCod 0)
T=Target Eb/No Margin, from 0 through 9 that is two times the Eb/No in dB
(from 0.0dB to 4.5dB).
Example: <0/ACM=0B12 (Sets min ModCod=0; max ModCod =11; maintains Tx
ModCod when remote demod unlocks; sets Target Eb/No at 1.0dB.)
Command only.
Directs the CDM570AL to retrieve a previously stored modem configuration from
the Configuration Memory location 0 through 9.
Example: <0/CLD=4 (retrieves modem configuration from location 4)
