AE HOST COMMANDS

The following sections describe the command status response (CSR) codes returned
by the Paramount MF 2 kW unit in response to a command, as well as the AE Host
commands for the Paramount MF 2 kW unit.

AE Host Command Status Response (CSR) Codes

When the Paramount MF 2 kW unit receives a command requesting a change in unit
operation (commands 1 through 127), or when the Paramount MF 2 kW unit receives
any command that it rejects (commands 1 through 255), 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.
