MODEL
49085D
Micro Link™ Peep-Hole Style
CFL/LCD Proof IR Receiver
INSTALLATION INSTRUCTIONS
DESCRIPTION
The Micro Link IR Receiver is a small peep-hole style infrared repeater
assembly. The Micro Link IR Receiver is equipped with a 7-foot cable and a
3.5mm stereo mini plug, which is plugged directly into the “IR RCVR” jack on
the connecting block, such as the models 789-44, CB60, and 791-44. The
Micro Link IR Receiver is primarily intended for use in installations where the
connecting block is within reach of its 7-foot cable – as when installing the
Micro Link IR Receiver in a cabinet where the controlled equipment is behind
closed doors.
FEATURES & SPECIFICATIONS
•Infrared carrier reception bandwidth: 30 – 60 kHz.
•IR carrier adjustment: 32 to 56 kHz (allows output carrier frequency to be
matched to a controlled component for optimum performance).
•IR reception range: > 50 feet.
•Dimensions: 2.75” Length x 0.75” DIA. Bezel is 0.90” DIA.
•Works in normal 3-wire model (12VDC, IR, GND).
•Red talkback LED for system verification.
•RF grid included for EMI interference reduction.
•Drives IR emitters through Xantech Connecting Blocks, Controllers, etc.
•Power requirements: +12VDC, 20mA.
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
MOUNTING
Drill a 3/4” hole in any surface, such as a cabinet panel. Pass the lead and
the body of the 490 through the hole and secure from the rear with the nut
(supplied).
PLACEMENT
The IR receiver should be located so that it is not directly facing a light
source such as lamps or displays (standard, LCD, and Plasma). When
mounted near a display, it should be flush to the display and away from light
reflections that may occur.
LOCAL SYSTEM APPLICATION
In this system a 283D Blink-IR Designer Emitter is shown connected to the
“OUT” jack. If expansion beyond two emitters is required, use a Xantech 789-
44, CB60, or 791-44 Connecting Block.

CABLE CONNECTIONS
490’s may also be used where the 7-foot cable is not long enough. Simply
cut off the mini plug, strip the leads and splice them to a 3-conductor
extension cable with a terminal block or other means. Then connect the
extension cable to the 3- or 4-terminal block on the connecting block.

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.
IR CARRIER ADJUSTMENT
The 49085D is factory set to an IR carrier repeat frequency of 38kHz. This
will be correct for the majority of installations. However, some manufacturer’s
components that you wish to control may use different carrier frequencies
(such as RCA DSS satellite receivers that use 56kHz). If carrier frequencies
fall within the range of 32 kHz to 56 kHz, you can adjust the 49085D to match
them for the best range performance. The adjustment can be made through
the small opening in the rear.
To adjust, proceed as follows:
1. First, try the 49085D in a repeater system. If it works well with good
range, do not make any adjustments!
2. If it does not work or has poor range (less that 15 feet), 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
until the remote control can control the component.
4. If you have products in the same IR system that has different IR
carrier frequencies, you will have to adjust the 49085D to a midway
position. For example, some may operate at 38kHz and others at
56kHz. In this case, set the adjustment to approximately 47kHz, a
midway position.
Note: Some products are more tolerant of compromised frequency settings
that 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.
Clock-wise (CW) Increase carrier frequency
Counter Clock-wise (CCW) Decrease carrier frequency

LARGE SYSTEM APPLICATION
The 490D Series IR receiver is compatible with all Xantech Connecting
Blocks. Different connecting blocks are provided for application specific
situations. For instance, in the diagram below, a 791-44 connecting block is
used to control several components.

TROUBLE SHOOTING:
1. Perhaps the most common problem you may encounter is stray IR
(infrared) or RF (radio frequency) interference preventing proper
operation of the controlled equipment.
•Fluorescent, Compact Fluorescent, Neon or Halogen lights,
Neon Art, and light dimmers.
•Direct of reflected sunlight.
•Infrared security sensors (active types).
•RF radiation from TV sets that may be close to the Hidden
Link IR Receiver.
2. You can confirm the source of the interference by temporarily turning
off TV sets, isolating the Hidden Link IR Receiver from all sunlight
and turning off all lights, light dimmers and Infrared security systems.
Then check to see if the Hidden Link IR Receiver operates the
component.
•Sometimes interference will cause the red Talk-Back LED on
the front of the Hidden Link IR Receiver to blink dimly,
intermittently, or continuously.
•The Talk-Back Led should only blink when you are sending
infrared commands to the Hidden Link IR receiver from a
remote control.
•It may be necessary to move either the interfering source of
the Hidden Link IR Receiver to achieve proper operation.
3. If the Talk-Back LED or the 286D Emitters do not blink when you are
sending IR commands to the Hidden Link IR Receiver from a remote
control, check the following:
•Make sure the power supply is plugged securely into a live
AC electrical outlet.
•Be sure the stereo mini plug of the Hidden Link IR Receiver
is plugged into the “IR RCVR” jack on the CB12 Connecting
Block, not into the “OUT” jack.
•Check to see that all the mini plugs are properly seated into
the mini jacks on the CB12 Connecting Block.
4. If the 286D Emitters blink, but the component does not respond,
reposition the 286D Emitter(s). They may not be located directly over
the component’s infrared receiving “window”. Consul the owner’s
manual of the unit or the manufacturer for the exact location of the
infrared “window”.
