WTE Output Control Protocol
Introduction
This section describes how to control the outputs of WTE Products via transmission payloads.
The WTE protocol needs to be able to switch many outputs on, and many off in a single
message. Receivers need to be able to be uniquely addressed, and in a manner that is
maintainable.
The output control protocol can also be used to direct commands or protocol messages to
specific remote units.
It may be likely that the payload is transmitted as part of a paging payload, such as POCSAG
or FLEX, but ultimately the transport method is irrelevant as long as it is capable of
transmitting the characters used by the protocol.
Once an output has been activated, it will remain in its activated state for its configured period.
This may be many seconds, or permanently latched.
The control message can be placed in any position in the message payload, and there can be
multiple control messages in the same payload.
Digital Output Format
The payload of a message must fit the following format in order to operate the unit outputs.
Note that this description is extended below to describe how this format is extended to also
allow control of analog outputs.
[[ID]EEEE-DDDD]
Where:
[ is the character ‘[’
] is the character ‘]’
ID is the OUT_ID that has been programmed (e.g. “01” or “Unit_A”). The ID may also
be a comma separated list of units (e.g. [01,Unit_A,03])
E is the output to enable (1-8 for the TReX). Up to 2 outputs can be specified.
- is the hyphen character ‘-’ All digits following the ‘-’ are outputs that are disabled
D is the output to disable
