Notes:
•
Commands are used as notifications. If an amplifier is switched ON, it will notify the other devices
on the Axium Bus by sending the Standby command (01). Any amplifiers with the same zone will
take the notification as a command and also switch ON.
•
When a command is sent to an amplifier it will first be transmitted on the Axium bus and then
returned to the PC (Home automation system). If an error occurs an error will be returned
instead of the original command. The PC (Home automation system) needs to ignore its
command when it is returned.
•
Standby B commands are ignored by AX450i amplifiers.
•
A Standby A or B ON command implies that the amplifier is not muted, if the amplifier was
previously OFF. A Mute command must follow the Standby command if it is muted.
•
The 'Track zone' command tells the zone specified to follow the source selection of the "Zone to
be tracked". This does not imply that the "Zone to be tracked" will also track the Zone amplifier.
It is normal that the program setting up the zone tracking will send two commands, one to get
Zone X to Track Zone Y, and another to get Zone Y to track Zone X.
Example strings:
010801 :
Standby A ON command for Zone 8
060002 :
+2db Treble setting on Zone 0
033102 :
Tuner source selection on Zone 31
0B0311 :
Volume down continuous push on Zone 3 keypad
Keypad key codes
An Axium Keypad may be directed to emit its learnt IR commands via RS232 control.
This is achieved by sending a 'Cause key press on Keypad' command, followed by the zone, and the
Keypad key code (data).
The Keypad key code is encoded with IR string repeats. (See table below)
To terminate a continuously repeating 'Key press', command a 00 keypad key code must be sent.
