Micro Link™ Peep-Hole Style
Standard IR Receiver
1
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
•Small size; mounts in 1/2” diameter hole. 2 inches deep (50mm).
•Quick-Connect 3.5mm Stereo Mini Plug on 7ft. cable for direct plug-in
to Xantech Connecting Blocks.
•Works in normal 3-wire mode (12VDC, IR, GND).
•Green Talkback LED for System Verification.
SPECIFICATIONS
•Infrared modulation frequency bandwidth: 25 – 60 kHz.
•IR reception range: Up to 80 feet, depending on remote control output
strength and ambient conditions.
•Reception angle: 55 degrees off axis for 50% range reduction.
•Cable requirements: 3-conductor. Use 24 gauge up to 200’, 22 gauge
up to 600’ 20 gauge up to 2000’, 18 gauge up to 5000’ – unshielded
OK.
•Max. transmission length: 1 mile using 18 gauge wire.
•Maximum current output: 100mA
•Drives IR emitters through Xantech Connecting Blocks, Controllers,
etc.
•Dimensions: 1/2” diameter x 2” deep (13mm x 50mm).
•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. (sold separately)
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 1/2” hole in any surface, such as a cabinet panel. Pass the lead and
the body of the ML85 through the hole and secure from the rear with the
nut (supplied).
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 an optional
Xantech 789-44, CB12, CB60, or 791-44 Connecting Block.
CABLE CONNECTIONS
ML85s 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.
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.

LARGE SYSTEM APPLICATION
The ML85 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 Micro
Link IR Receiver.
2. You can confirm the source of the interference by temporarily
turning off TV sets, isolating the Micro Link IR Receiver from all
sunlight and turning off all lights, light dimmers and Infrared
security systems. Then check to see if the Micro Link IR Receiver
operates the component.
•Sometimes interference will cause the red Talk-Back LED
on the front of the Micro Link IR Receiver to blink dimly,
intermittently, or continuously.
•The Talk-Back Led should only blink when you are
sending infrared commands to the Micro Link IR receiver
from a remote control.
•It may be necessary to move either the interfering source
of the Micro 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 Micro 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 Micro 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 283D Emitters blink, but the component does not respond,
reposition the 283D 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”.
