High-Power TWTA Satellite Terminals Programming Guide for Redundant Controller
Rev. 1 A–11
A.3.1 Controller Query Commands
The controller query commands and responses are listed in Table A-5.
Table A-5. Redundant System Controller Query Commands
ASCII Description
0 ID/Version. Returns a 10 character string identifying the controller model number and software revision.
The first 7 characters define the model number, the 8th character is the software major revision, and the
9th and 10th characters are the software minor revision numbers.
1 Summary Status. Five bytes of status are returned.
