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.

• Includes 789-44 Connecting Block, Power supply, and four 283D emitters

for easy system installation.

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.

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 the included
Xantech 789-44 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, an optional 791-44 connecting block is used
to control several components.

Micro-Link (ML) IR Receiver Kit

DESCRIPTION

The ML Series Kit comes with everything needed for a complete IR repeater
system. With a Xantech IR Kit, equipment can now be concealed for clean
room design. In addition, a centralized IR receiver means there is only one IR
target resulting in improved remote control interaction. Featuring color-coded
connectors, a Xantech IR Kit is now an easy to install, and allows a worry-free
installation.
