The bi-directional IR system allows you to control the source that is connected to the extender unit, from the
display; or the display from the source, not simultaneously. There are two important things to note when
setting up the IR system:
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; or at the source for controlling the display.
2. The IR Blaster (IR TX) is what sends the IR signal to what you are intending to control, whether it’s the
source or the display. 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. Or placed at the display to control the display
from the source.
IR BLASTER (TX)
To control the source: Plug IR Blaster into IR TX port of transmitter unit (280621-TX); place transmitter in
front of the IR eye of the source.
To control the display: Plug IR Blaster into IR TX port of receiver unit (280621-RX); place transmitter in front
of the IR eye of the display.
Note: Placement of the IR Blaster is important and can result in the IR system not working 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:
