VIRTUAL OUTPUTS AND CONTROL
Virtual outputs are a used to invoke 12-90 actions remotely. These actions include control
over triggering of inputs and periodic messages. Virtual outputs can be used to return
information about the last received message, such as the received signal strength and
checksum information.
over triggering of inputs and periodic messages. Virtual outputs can be used to return
information about the last received message, such as the received signal strength and
checksum information.
Virtual outputs are addressed in exactly the same fashion as the on board relay.
The following examples assume a unit ID of 23.

Trigger the unit ID , message length and checksum to be
transmitted.
A message of “C A1234560 2 test 01079” will result in unit 01
responding with “010A02E1” where first 2 digits are the
responding unit ID, the second 2 digits are the message length in
hex, the last 4 digits are the message checksum in hex. The
length and checksum are calculated ov er the message payload
“test 01079”. The checksum is the sum of each ASC II v alue in
the message (e.g. 116+101+115...). The responding unit will use
the same cap code as used by the “serial passthrough” mode of
operation.

Trigger receiv ed signal strength message to be transmitted. This
is the signal recorded when this message is receiv ed. This
feature is v aluable for checking system health or for initial system
configuration. This mess age is transmitted to the first cap code
programmed in the first cap code range. The first 2 characters of
the returned message is the unit ID of the responding unit.
Returned example message will be: 01:-87dBm.
