➔
Bi-directional IR control extension is supported and may be used simultaneously with
RS-232.
➔
Set the Control Rotary to adjust the IR In mode for IR Sensor (default at Rx unit) or
Serial IR (default at Tx unit)
➔
Tx Unit IR In corresponds with Rx unit IR Out. Tx Unit IR Out corresponds with Rx
unit IR In.
