There may be situations where the IR sensor is blocked by a cabinet or other mounting
device. In this case, the included IR extender (Gefen part no. EXT-RMT-EXTIRN) can
be connected to the IR In/Ext port on the rear panel of the matrix. The sensor on the IR
extender behaves exactly like the sensor on the front panel of the matrix. Always point the
IR remote control unit in the direction of the IR sensor.
The IR In/Ext port can also receive electrical IR signals from an Automation Control
System. Connect a 3.5mm-to-3.5mm mini-stereo cable from the IR In/Ext port to the port
on the control system.
