INSTALLATION
QUICK-START
A typical system will use an IR receiver, several emitters, and a power supply
all connected to a connecting block.
1. Connect the IR receiver to the “IR RCVR” port on the connecting
block. The ‘red’ connector is installed to the ‘red’ plug.
Note: In some extended distances, additional 3-conductor may be required and can
be connected to the terminals on the connecting block.
2. Connect the Emitters to the connecting block. The ‘yellow’ connector
is installed to the ‘yellow’ plug.
3. Connect the power supply to the connecting block.
4. Installation

ADJUSTING IR CARRIER FREQUENCY
The IR receiver is factory set to an IR carrier frequency of 38kHz. This will be
correct for the majority of installations, however, some manufacturer’s
components that you wish to control may use difference carrier frequencies
(such as digital cable boxes which use carrier frequencies between 52kHz
and 56kHz). If such carrier frequencies fall within the range of 32kHz to
56kHz, you can adjust the IR receiver to match them for best range
performance. The adjustment can be made through a small opening on the
rear of the unit.
To adjust, proceed as follows:
1. First, try the IR receiver in the system. If the system controls all the
desired components with adequate range, do not make any
adjustments.
2. If the system does not work or has poor range, determine the IR
carrier frequency of the product you wish to control. Contact the
manufacturer of the product, if necessary, to determine this
frequency.
3. Using a small blade type screwdriver, rotate the adjustment shaft
slightly either clockwise to obtain carrier’s less than 38kHz or
counter-clockwise to obtain carrier’s greater than 38kHz.
4. If you have audio/video equipment in the same system that have
different IR carrier frequencies, you will have to adjust the IR receiver
to the midway position. For example, some products may operate at
38kHz and others at 56kHz. In this case, set the adjustment in
between this range so both products can operate in the system.
Note:
Some products are more tolerant of compromised frequency settings than
others. You may have to “fine tune” the adjustment to “favor” the least tolerant
component for the best performance of all units in the system.
