Response String Structure

Characters in response strings are expressed in a combination of hex and ASCII characters. For clarity,

the following protocol examples use the following conventions:

ASCII characters or strings are shown enclosed in single quotes

Numbers shown that are not in single quotes are a single decimal byte

Parameters shown in < > brackets are single byte

A series of multiple commands or parameters are set apart by [ ] brackets

Commas separate the bytes, but are not part of the protocol

Double quotes enclose the command string, but are not part of the protocol

Command format

The zone or high order byte of the device

The unit or low order byte of the device (0 for global zone)

The number of response bytes to follow
