AE BUS COMMAND STATUS RESPONSE (CSR) CODES
When the HFV generator receives a command requesting a change in unit operation or
status (command numbers 1 through 127), it responds with a command status
response (CSR) code. The CSR is a single-byte number that indicates whether the unit
accepted or rejected the command and, in the case of rejection, the reason the unit
could not respond to the command. Use
