84 Node, Channel and Subchannel Assignments
9/15/93
Every device in a MicroTrac system is identified with a Node number, a Channel
number, and a Subchannel number, regardless of whether the device uses the
Local Area Network or not. These identifiers have different significance for each
device and some devices may not need all three fields to provide a unique
identification. This appendix lists each device type relating to the VCD 723, and
describes the significance of each field for that device. Node, Channel
