Troubleshooting
If the switcher does not properly respond to IR remote control
functions, check the following:
• You may be too far from the switcher. The maximum operating
range is 30 feet.
• You may be too far to the side of the switcher. The remote
control must be pointed within 30 degrees of the switcher’s IR
sensor for best results.
• You may be taking too long to enter the sequence. The unit
times out if no command is received in 5 seconds.
• The two AAA batteries may be dead. Replace the batteries as
shown in figure 1.
• The switcher’s front panel security lockout may be on. Toggle
the security lockout off. See the appropriate switcher’s
manual.
• The room lighting may be interfering with the IR signals. Keep
the switcher out of bright light.

Introduction
About this User’s Guide
This user’s guide covers the Extron IR 501 Small Matrix Infrared
(IR) Remote Control, part #70-336-01. The IR 501 is an optional
remote control that works with Extron matrix switchers. The
remote control can duplicate most of the matrix switcher’s front
panel control functions and some of RS-232 control functions.
The hand-held remote operates at a carrier frequency of 38 kHz.
Refer to the appropriate matrix switcher manual for
definitions of ties, configurations, presets, and audio
breakaway; and for more detailed descriptions of the
switcher’s front panel indications.
Battery Installation
Install two AAA batteries as shown (figure 1).

IR 501 Buttons
Aim the hand-held unit at the IR detector on the switcher and
press the desired buttons on the remote. The maximum
operating range is 30 feet.
After the definitions of the IR 501’s buttons, see Operations for
examples of using the IR 501 to perform various functions.

Switcher Indications
It is not the purpose of this manual to define
the switcher’s front panel indications, but two
of the switcher’s LEDs indicate operation by
the IR 501 remote control (figure 3).
Other indications are identified where
appropriate in the Operations section.
Infrared remote sensor — This

sensor receives infrared (IR) signals from the optional
IR 501 small matrix universal remote control. The IR
remote control must be pointed within 30 degrees of this
sensor for best results.
Power LED — This LED blinks off and on to indicate that

an IR signal has been received.
Audio Setup LED (A/V switchers only) — This LED lights

for a second when an improper or unexpected IR
command is received.

Sample Operations
The following examples show operations with specific
input, output, and preset numbers. Use your own
numbers as desired.
The switcher’s Power LED flashes whenever the switcher
receives an IR command. Other switcher indications are
identified in the following examples where appropriate.
For detailed descriptions of how the switcher indicates ties
and presets, refer to the appropriate matrix switcher’s
manual.
Many operations require a sequence of IR commands.
When multiple IR commands are required, the entire
sequence must be completed within 5 seconds. If a valid
sequence is not completed within 5 seconds, the switcher
times out and discards all received IR commands
