Xantech Universal Remote ML85K User Manual

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.  
INSTALLATION INSTRUCTIONS  
Includes 789-44 Connecting Block, Power supply, and four 283D emitters  
for easy system installation.

LARGE SYSTEM APPLICATION  
1.  
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.

Signal and ground wires are  
reversed or shorted either at the

troubleshooting countermeasures you will have to take may vary from job  
to job. Each installation is different due to the number of IR receivers in  
use, length of wire runs, type of wire, amount of ambient IR noise present,

from nothing at all, to any combination of the solutions listed below.

Solution  
Component to Test Instructions  
Reposition the Emitter so that it is directly  
over the components sensor window.  
Consult the components owners’ manual of  
the unit for the exact location of the IR  
Sensor Window.  
With a Multimeter, measure the DC Voltage of the  
supply while it is connected to the Connecting Block.  
Put the Negative lead of the meter on the terminal  
marked GND and the Positive Lead on the terminal  
marked 12VDC (or V). You should get a reading  
1. Emitter placement is incorrect.  
between 11.5VDC and 13.0VDC. If not, remove the  
supply from the Connecting block and measure again  
1. Verify Power Supply this time directly on the 2.5mm Coaxial plug. If it  
reads between 11.5VDC and 13VDC, power supply is  
most likely good. Reconnect to the Connecting Block  
and proceed to step 2. NOTE: In most cases this  
will indicate the supply is good but in some cases  
the supply can still be bad (i.e. reads good when  
not plugged in but may not be able to handle the  
current load of the system.)  
Reposition the Emitter to a position that is  
suitable for the unit. Use a 283 or 286D Blink  
style emitter (they have a lower output than  
non-blink emitters 282 and 284M). If the  
components do not need to be controlled  
directly without an IR Repeater system  
(components are located in an equipment  
closet), place a Mouse Emitter Shield cover  
over the Emitter (PN#MS1). The rounded  
(non-stick) side of the emitter is a hi-output  
side and can reflect off other devices and  
overpower some components IR Sensors. If  
using a CB12 connecting block, try a 789-44  
connecting block. This has a series resistor  
at the output, which will limit current to the  
Emitter.  
Emitter placement is correct  
but the signal is overpowering  
2. the unit or there is bleed-  
through from other emitters  
close by.  
Remove the power supply from the connecting block  
and all Emitters from the output. Place a jumper wire  
on the connecting block between IR and +12v.  
Reconnect the Power Supply and one emitter. The  
Emitter should Light bright and solid. Repeat for all  
emitters.  
Verify Emitter. (283D  
or 286D Blink Style  
ONLY)  
2.  
Use a diode tester to verify proper Emitter operation.  
Remove Emitter from Connecting Block. Place the  
Positive Lead of the tester on the TIP of the Mono  
Mini Plug and the Negative Lead on the Shield of the  
Mono Mini Plug. Meter should read a voltage. When  
the leads are reversed (Positive lead on Shield and  
Negative lead on TIP) you should not get any voltage  
reading at all.  
Verify Emitter. (282M  
or 284M NON Blink  
Style)  
3.  
Remove the power supply from the connecting block  
and all Emitters from the output. Place a jumper wire  
on the connecting block between IR Signal and GND.  
Reconnect the Power Supply. With a known good  
hand-held remote, shoot a constant IR Command at  
the receiver and verify the TB LED on the Receiver  
lights.  
4. Verify IR Receiver.
