1. ON/OFF - Press the Power button on the IA-1250 IR Remote to turn the zone ON. Press again to turn
the zone OFF.
2. Bus/Line - Press the Bus button to select the source connected to the IA-1250 Audio Bus In (if used).
Press the Line button to select the source connected to the local zone Line IN.
3. VOLUME/MUTE - Press the Volume UP/DOWN buttons to increase/decrease zone volume. Press the
Mute button once to mute local zone audio. Press again to un-mute local zone audio.
4. TREBLE/BASS - Press the Treble/Bass +/- buttons to adjust local zone treble/bass.
IMPORTANT NOTE - The only way to accurately reset treble/bass 'flat' (audio signal pass-through) is
with RS232 commands! There are no treble/bass 'flat' IR commands!
4. BALANCE LEFT/RIGHT - Press the Balance L/R +/- buttons to adjust local zone left/right balance.
IMPORTANT NOTE - The only way to accurately reset left/right 'center' (audio signal pass-through) is
with RS232 commands! There is no balance 'center' IR command!
BUS AUDIO IN - Zone audio can also be switched to the Audio Bus IN using a voltage trigger on any zone(s)
where audio paging or other temporary 'Bus' audio source may be desirable.
RS232 CONTROLLED
This mode would typically be used when the IA-1250 is being used in a more sophisticated system with
advanced control (RS232) capabilities. All of the functionality detailed in the Voltage Controlled and IR
Controlled can still be incorporated into a system with RS232 control, but RS232 control adds even more
flexible and precise control. The IA-1250 can respond to specific RS232 commands and send status back to
a controller or display for verification of zone settings.
Use the tables on the following pages to configure an appropriate RS232 controller with commands for
Zone ON/OFF, Volume/Mute, Input, Treble/Bass, etc. Commands can be discreet ON/OFF, ramping volume
or specific audio levels, incremental treble/bass or step increase/decrease, specific input select or toggle
input.
The IA-1250 RS232 section can automatically return Zone Status Updates that will show any changes to
zone settings made by the IR remote or voltage triggers as individual changes or complete zone status.
Queries can also be configured to ask and confirm specific zone settings including all RS232 controlled
functions and zone status.
Specific control and functionality may vary from system to system, given the types of controllers used and
system configuration, but overall RS232 functionality should be pretty straight forward for anyone familiar
with this type of setup.
