Connecting IR Control

Source Device Control using IR

Attach the IR emitter to the IR receiver of the source device, insert the TS 3.5 mm plug of the emitter to the 

IR 

OUT

port of the DL-HD70 transmitter. Insert the TS 3.5 mm plug of the IR receiver (eye) to the IR IN port of the 

DL-HD70 receiver.  Point the source device IR remote at the display location where the IR receiver is located, IR 

signals will now travel through HDBaseT to the DL-HD70 transmitter side where the IR emitter is attached to the 

source device. 

Attach the IR emitter to the IR receiver of the display device, insert the TS 3.5 mm plug of the emitter to the

IR OUT

 port of the DL-HD70 receiver. Insert the TS 3.5 mm plug of the IR receiver (eye) to the I

R IN 

port of the 

DL-HD70 transmitter.  Point the source device IR remote at the source device location where the IR receiver 

is located, IR signals will now travel through HDBaseT to the DL-HD70 receiver side where the IR emitter is 

attached to the display devic

e.

The  DL-HD70  is  capable  of  transmitting  bi-directional  IR  signals  through  the  HDBaseT  circuit.  The  DL-HD70 

comes with 2 IR receivers (eye) and 2 IR emitters (flashers) so you can control devices from either end of the 

extender circuit.

Remote Display using IR

To pass 3rd party IR system signals through the DL-HD70, such as a control system, connect the TS connector 

of the IR-AC coupling cable (provided) to the IR output port of the control system and connect the TRS connec

-

tor of the IR-AC cable to the IR IN to either transmitter or receiver of the DL-HD70.

Source / Display Control from Control System

Passing IR Signals:

The DL-HD70 is capable of passing IR signals between 33 and 55 KHz. To prevent damage to 

any of the electronics, the extenders should be powered off while inserting or removing any IR 

components. Inserting an IR transmitter into the IR IN port may damage the IR circuit for that 

extender.
