AE Bus Commands

The following sections describe the command status response (CSR) codes returned
by the Pinnacle in response to a command as well as the AE Bus commands for the
Pinnacle.

AE BUS COMMAND STATUS RESPONSE (CSR) CODES

When the Pinnacle 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 Table 4-17 to interpret the CSR codes.
