Operation Manual

Command examples, RS-232 source sends:

$s99sbyo <line feed> > All units enter standby

$s04comon<line feed> > Turn on RS-232 communications for zone 4

$s05como<line feed> > Turn o RS-232 communications for unit 2, zone 1

$s99comen<line feed> > Turn on RS-232 communications for every zone on every unit

$s09comdis<line feed> > Turn o RS-232 communications for every zone on unit 3

$s02src2<line feed> > Sets zone 2 (unit 1 zone 2) to source 2

$s10src3<line feed> > Sets zone 10 (unit 3 zone 2) to source 3

$s08vo+<line feed> > Increments volume on zone 8 (unit 2 zone 4)

$s03vo-<line feed> > Decrements volume on zone 3 (unit 1 zone 3)

$s14vol012<line feed> > Sets absolute volume level of zone 14 (unit 4 zone 2) to level 12

$s99muten<line feed> > Mutes every zone on every unit

When MULTIzone is powered on, the previous status of the unit will be restored. If a particular zone of the unit was previously in

RS-232 mode the particular settings for that zone will be restored, e.g. the source input, volume level, or mute. Alternatively, if a

particular zone was in manual panel mode the front controls will become active.

Before a zone can be brought under RS-232 control it must rst be switched from manual panel mode to RS232 by using the

“comon” for a particular zone, or the “comen” system wide or unit command (all described above).

Note: the front panel controls will be disabled when the unit is in RS-232 mode. Make sure the required unit zones are brought

out of RS232 by sending the appropriate “como” or “comdis” commands.
