B.3 Redundancy Operation using Serial-based Remote Commands and Queries
See Chapter 5. SERIAL-BASED REMOTE PRODUCT MANAGEMENT for detailed information about using the HPOD
EIA-485/232 serial interface.
Index Notes: Columns marked ‘X’ designate instruction code or system compatibility as follows:
• Instruction Code – Column ‘C’ = Command; Column ‘Q’ = Query; ‘X’ indicates Command only, Query only, or Command/Query;
• Redundancy System Compatibility – ‘X’ indicates 1:1 systems only, 1:2 systems only, or both 1:1 and 1:2 system compatibility
CODE C Q DESCRIPTION 1:1 1:2
FBU X X Forces one of the online units to be a backed up for maintenance and test purposes X
ONL X X Sets or returns the online status (i.e., online, offline) X
CRA X X Permits configuration of the redundancy amplifier mode in 1:1 and 1:2 redundancy systems X X
RAM X X Sets or returns the redundancy mode (i.e., MANUAL or AUTO) X
RED X X Sets or returns the redundancy state (i.e., 1:1 or 1:2) X X
SSW X X Forces switch position (i.e., SSPA 1 or SSPA 2 online) X
GOF X X Sets or returns the gain offset in a 1:1 system to equalize attenuation levels X
SBO X X Sets or returns the gain offset in a 1:2 system to equalize attenuation levels X
NOTE – Instruction Code Qualifiers, as defined in Sect. 5.4.2.5, are used in the command/query table ‘Response to Command’ column:
= Message OK * Message OK, but not permitted in current mode
? Received OK, but invalid arguments found # Message OK, but unit is not in Remote mode
! Invalid instruction
