IR In:
The IR In port is different for the Tx and Rx units. The Tx unit’s IR In port
supports a Serial IR (hardwired) connection. The Rx unit’s IR In port supports an
IR Sensor.

Extending IR or RS-232 Control
RS-232:
Bi-directional RS-232 is achieved utilizing the IR Out (RS-232) port on the Tx and Rx
units. The connector is 3.5mm stereo and the pinout is the same on the Tx and Rx
unit.
RS-232 can not be used at the same time as IR.
