INSTALLATION INSTRUCTIONS
490-85
CLF / LCD Friendly Micro Link IR Receiver
DESCRIPTION
The 490-85 is a CFL (compact fluorescent light) / LCD (liquid crystal display) version of the 490 Micro
Link series IR receivers. It is specifically designed to have greater immunity to high frequency
ballasted CFL and overhead fluorescent type infrared inference and to have exceptional IR reception
range.
These small IR receivers have been designed primarily for mounting in panels, doors, cabinets, etc.
for control of A/V equipment behind closed doors. They may be mounted in walls, ceilings, wall
speakers, etc. - anywhere an inconspicuous appearance is desired. Their high sensitivity allows
placement behind speaker grilles and still receiver IR commands up to 20 feet away.
FEATURES AND SPECIFICATIONS
IR carrier frequency reception bandwidth: 30 to 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 mode (12VDC, IR, GND).
Red talkback LED for system verification.
RF Grid included for EMI interference reduction.
Includes 3-Terminal Block for easy extension of 7 foot ribbon cable.
7 units may be powered by one 781RG power supply.
Normal Operating Power: +12VDC, 20mA.
Note: The 490-85 will not operate in 2-wire Phantom Power mode.
INSTALLATION
This unit is meant to be interfaced to Xantech Connecting Blocks, such as CB12, 789-44, 791-44, etc.
MOUNTING
1. Drill a 3/4” hole in any flat surface, such as a cabinet panel. Pass the cable and body of the
490-85 through the hole and secure from the rear with the nut (supplied).

IR CARRIER ADJUSTMENT
The 490-85 is factory set to an IR carrier repeat frequency of 39kHz. 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 sure carrier
frequencies fall within the range of 32kHz to 56kHz, you can adjust the 490-85 to match them for the
best range performance. The adjustment can be made through the small opening on the rear.
To adjust, proceed as follows:
1. First, try the 490-85 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 than 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 slot lines up with the
desired frequency.
4. If you have products in the same IR system that have different IR carrier frequencies, you will
have to adjust the 490-85 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
490-85 CABLE CONNECTIONS
The 490-85 may also be used where the 7-foot lead is not long enough. In this case, simply cut off
the mini plug, strip the leads and connect them to a 3-terminal block. For correct color identification of
wires, refer to the following tables and diagrams:

APPLICATION WIRING
A typical system, with a 490-85, 781RG Power Supply and 283M Emitters plugged into a 791-44
Connecting Block, is shown in the figure below.
1. Plug the 3.5 mm stereo mini plug from the 490-85 into the 791-44 connecting block labeled “IR
RCVR”.
2. Plug in the 3.5 mm mono mini plug from any of the 282, 284, 283 and 286 series Emitters into
the jacks labeled EMITTERS on the 791-44 Connecting Block and affix the opposite end of the
IR Sensor Window of the controlled equipment.
3. Plug in the 2.1mm Coaxial power plug of the 781RG Power Supply (not included) into the jack
labeled 12VDC on the 791-44 Connecting Block.
4. Plug the AC end of the 781RG Power Supply into an ‘un-switched’ 120VAC outlet.
