TA (Tell Alarm)
[Status]
DESCRIPTION:
The TA command checks the alarm output of the amplifier on the side connector. If no alarm is present, the
controller returns 153 decimal, or 99 hex, which is the code for “No Alarm.” If the alarm output is active,
the controller requests the alarm code serially from the amplifier via the mating connector. See the Sigma
II documentation for all the possible alarm codes.
NOTE: The amplifier requires special firmware to transmit the alarm code to the controller. Consult the
factory for details. Firmware in the amplifier is not field upgradable.
