Note1: Volume up or down requests increase or decrease volume level by 5

Note 2: Treble and bass commands use hexadecimal values 0-F, default (flat) is 8.

Note3: After “Channels Off (#of)” command an “Un-mute command (#um)” must be sent to each channel to restore a channel volume.

Also, it is best to leave about a ½ second between commands, as some commands may be missed if they are entered too quickly.

All commands also send a message back to the terminal after they have been completed, so that it is easy to keep track of the previous commands that were sent.

Note: Some commands are read or write only and some are both – for example: Mute All is a write only command and Version is a read only command.
