RS232 Protocol—Continued

■A Standby 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.

■Not all Command and Data commands are covered in this document.

■The expected reply for the “Send all Parameters” command (09) is >144 bytes. All command fields listed in this document are contained in the reply. The reply also contains advanced commands not listed in this document. The home automation or PC’s buffer should be large enough to receive and process the 144-byte reply.

■If two pairs of zones are linked on an MZA-4.7, i.e. zones 1 & 2 and zones 3 & 4, and a “Link Zone” command is sent that links zones 2 & 3, then the MZA-4.7 has the following implications:

•Zone 2 links to Zone 3

•Since zone 2 is no longer linked to zone 1, zone 1 shall no longer be linked to zone 2.

•Since Zone 3 is no longer linked to zone 4, zone 4 shall no longer be linked to zone 3.

Example strings:

010A01: Standby ON command for zone 10 amplifier

012A01: Standby ON command for zone 10 preamplifier

060002: +2dB Treble setting on zone 0

03IF02: S7 source selection on zone 31 amplifier

0B0311: Volume down continuous push on zone 3 keypad
