Action Commands

Establishes the unit address.

In some units, address is set by DIP switches or jumpers, in which case this command takes no effect. Some other units require the address to be set with this command.

CMD: 'A'
DATA: address (Hex)

Establishes an alarm condition (code) in the unit forcing the ALARM LED to illuminate.

CMD: '!'
DATA: alarm code (1 byte)

Code zero means no alarm condition, so asserting this command with argument zero effectively clears the alarm condition turning the ALM LED off. This can also be done using address Fh (broadcast) to clear all units at once.

Broadcasting an alarm code other than zero is illegal resulting in error.

Activates given GPO.

CMD: 'G'
DATA: GPO number in Hex (2 bytes)

Deactivates given GPO.

CMD: 'g'
DATA: GPO number in Hex (2 bytes)

Deactivates all GPOs in the unit and clears alarm condition.

CMD: 'r'
DATA: none
