HEX Codes for System Integration
Comments/Notes
All Commands below use 00 for the Unit Address number. When the unit address is changed, Byte
number 6 (the Checksum Byte) increments by one step in Hex. For example, using the Discrete On
Command on with the unit address changed to 01; the Checksum Byte changes to 26. The various
commands below have been grouped together based on common function. On Off, Input Selection
and Volume are together; Direct Mode and Mode related are together, etc. Some commands require
settings that can only be made in the PC program. Sending the command without rst dening the
settings in the PC program will result in nothing happening at all or improper functioning of the unit.
