Description of Arguments
Query
Command or Query.
Redundancy mode in the form x,abc, where:
For x:
0 = No Redundancy
1=1:1 modem (back-up modules at Slot#3 and Slot#4), or
1:1 Tx (back-up Tx on Slot#4), or
1:1 Rx (back-up Rx on Slot#4)
2=1:2 Tx, or 1:2 Rx (back-up module on Slot#4)
3=1:3 Tx, or 1:3 Rx (back-up module on Slot#4)
4=Reserved
For abc:
000=no redundancy or 1:1 modem or 1:3 Tx or 1:3 Rx.
If a=1, Slot#1 is selected as primary, otherwise it's not.
If b=1, Slot#2 is selected as primary, otherwise it's not.
If c=1, Slot#3 is selected as primary, otherwise it's not.
Note: The settings on a,b, and c fields are only required if Qx is in 1:1
Tx or 1:1 Rx or 1:2 Tx or 1:2 Rx .
Example: IRM =1,000 (1:1 modem)
IRM =1,010 (1:1 Tx or 1:1 Rx with primary at Slot#2)
Command only.
Resets internal pointer to allow RNS? Queries to start at the
