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 complete
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.
REMOTE ROOM APPLICATION
One application is to locate the IR receiver in a remote room. This will give
the end-user the ability to control audio/video equipment from a location
where the remote control no longer has the ability of direct line-of-sight.
The IR receiver will need the 3.5mm stereo type mini plug removed to extend
the wire run to the connecting block. A 3-terminal block is supplied to connect
the IR receiver to the connecting block with a 3-conductor inter-room cable in
between.
The 3-conductor inter-room cable (24 gauge up to 200’, 22 gauge up to 600’,
20 gauge up to 2000’, 18 gauge up to 5000’), is run to the main room.
While it is possible to make wired connections without the connecting block,
it is not recommended. The connecting block reduces installation time, helps
to eliminate errors, allows easy troubleshooting and permits easy system
upgrades later, if needed.
Input connections must be made as illustrated. To extend the emitter wires to
a more distant location, you may splice in 2-conductor wire, in the wire
gauges mentioned before, as needed.
LOCAL SYSTEM APPLICATION
Another application is to locate the IR receiver in a central location, such as
the TV, video screen and/or a speaker. The audio/video equipment can then
be hidden inside a cabinet or located away from the front of a room. This will
give the end-user the ability to direct a remote control to one central location
and not have to worry about aiming to the respective device to be controlled.
Since the IR receiver is in close proximity to the audio/video equipment, no
wiring extension should be required so long as the connecting block is within
reach of the 7-foot cable. The 3.5mm stereo type mini plug is connected to
the “IR RCVR” jack on the Xantech Connecting Block.
