1. The IR Receiver (IR RX) is always what you point your remote at to send an IR signal. This pigtail is placed
at the display for controlling the source
2. The IR Transmitter (IR TX) is what sends the IR signal to what you are intending to control. This pigtail is
placed at the source; either pointed at the source, or placed on the front panel of the source (see below
for placement tips)
IR PASS THROUGH
The IR system allows you to control the source that is connected to the extender unit,
from the display. There are two important things to note when setting up the IR system:
IR TRANSMITTER (TX)
To control the source: Plug IR Blaster into IR OUT port of transmitter unit (HD4KEX30-
TX); place blaster in front of the IR eye of the source
Note: Placement of the IR Blaster is important and can result in the IR system not work-
ing if improperly placed.
•
First, locate the IR eye or window on the source
•
If placing the IR blaster right on the front panel of the source, do not stick right on top of
the IR eye or IR window. The IR signal cannot travel through the double-sided tape on the
Blaster. Instead place the blaster on either side, or on the top or bottom of the IR eye or
window, with the tip of the blaster facing the IR eye or window. See below for illustration of
where IR signal shoots from on IR Blaster:
