MASTER CONTROL IN
This connection allows voltage control of 0E-IA1250
ON/OFF. Applied voltage (+3 to +30VDC @1mA)
will turn the amp ON. When voltage is cut, the amp
will turn OFF. (OFF, not Standby.)
NOTE: The Power Switch must be in the OFF
position when using this feature. With this feature
the IR and RS232 controls will not turn a zone ON
or have any other control unless proper voltage is
applied to the Control IN.
1. Master Control IN - Using a 2 circuit 3.5mm
mini plug, connect the voltage trigger to the
Master Control IN. C3 to +30VDC
@1mA from the trigger device to the striped wire
(tip). Connect GND from the trigger device to the
unmarked wire (sleeve).
MASTER CONTROL OUT
This connection provides a voltage control OUT
that can be used for triggering voltage controlled
system devices that need to be turned ON when
any 0E-IA1250 zone is active. When any 0E-IA1250
zone is ON, the Master Control OUT will output
+11.5VDC@1mA-10VDC@5mA. If all zones are
OFF, the Master Control OUT will output 0.0VDC.
1. Master Control OUT - Using a 2 circuit 3.5mm
mini plug, connect the 0E-IA1250 Master Control
OUT to the voltage controlled device(s). Connect
the striped wire (tip) to +12VDC on the controlled
device. Connect GND the unmarked wire
(sleeve) to GND on the controlled device.
RS232 I/O
This connection provides a two-way communication
terminal for control/status feedback of the 0E-
IA1250 from/to an automation system or other
appropriately capable device.
1. RS232 - Using a DB9 Patch Cable, connect the
0E-IA1250 RS232 Terminal to an appropriate
RS232 terminal on an automation system
controller or other device. 0E-IA1250 RS232
DB9F pin-out is as shown. Please refer to the
control device’s owner’s manual to confirm
RS232 terminal pin-out.
