Detailed Description

The protocol used for data transmission requires each message to be tagged with a channel and source ID. While source IDs are required to be unique on a given system, some channel numbers are common to all sources.

As with source IDs, channel IDs range between 0 and 127. The mandatory channels are described here, with the remaining numbers available for use as required by any given source.

The three log message types would not normally be included in a sources channel map, but are available for use by any device.
