Xantech Wall Link WL25 User manual

INSTALLATION INSTRUCTIONS
WL25
Wall Link™
Standard IR Receiver
2
DESCRIPTION
The WL25 is designed to reject interference from CRT, DLP and LED
Displays. This IR Receiver mounts easily into a single gang, electrical J-Box,
is supplied with mounting screws, and comes with a Decorator-style insert,
allowing the installer to use a Decorator-style wall cover plate. This provides
an integrated look for control of A/V equipment behind closed doors or any
IR Repeater System that is in close proximity to light sources described
above.
FEATURES
• J-Box Mounting with Decorator-style insert (available in white (included),
ivory, almond, & black)
• 4-screw terminal block for interface to Xantech Connecting Blocks
• Works in normal 3-wire mode
• RF Grid included for EMI reduction
• Talk Back LED for IR reception and full system operation indication
• 7 units may be powered by one 781ERGPS power supply (regulated
12VDC 200mA supply)
Note: The WL25 will not operate in 2-wire Phantom Power mode
SPECIFICATIONS
• Infrared modulation frequency bandwidth: 25 - 60 kHz
• Reception range: up to 80 feet (18M), depending on remote control
output strength and ambient conditions.
• Reception angle: 55 degrees off axis at 50% range reduction
• Cable requirements: 3-conductor. Use 24-gauge up to 200' (61M), 22
gauges up to 600' (180M), 20-gauge up to 2000' (600M), 18-gauge up to
5000' (1.5KM) -- unshielded OK.
• Maximum transmission length: One mile using 18-gauge wire (1.6KM)
• Maximum current output: 100 mA (pulse)
• Dimensions: 1-3/4” W x 4-1/8” H x 1-1/8” D
• Power requirements: 12 volts DC @ 20mA

INSTALLATION
This unit is meant to be installed into a standard J-Box mounting box and
interfaced to Xantech Connecting Blocks, such as the CB12, 789-44, 791-
44, etc.
Figure 1 – WL series Assembly
CAUTION: THE J-BOX MUST NOT BE SHARED WITH 120/240VAC
CIRCUITS.
PLACEMENT
Placement of the IR Receiver does matter when used in the presence of a
Plasma Display. Ideally it should be placed somewhere around the Display
with the front of the receiver flush with the front of (or set back from) the
Display. If the WL25 needs to be placed in front of the display (such as on
an adjacent side wall perpendicular to the display), make sure it is placed at
a location at least 45 degrees off axis from the corners of the unit – see
Figure 2. The presence of Direct Sunlight and Fluorescent Lighting should
not affect the reception of this unit.

Figure 2 – WL series Placement
NOTE: Plasma interference can be reflected off of any item within approx. 3
feet from the front of the display. Keeping this in mind, make sure that the
WL25 is free of any obstruction that might reflect back into the receiving eye.
Note: While this unit shows strong rejection to standard 50/60Hz ‘ballasted’
fluorescent lighting, it is still prone to interference from CFL style Fluorescent
lighting.
MOUNTING
1. Pre-wire a 3-conductor cable (refer to Specifications section for
proper Wire Gauge) from the connecting block location to J-box
mounting location.
2. Connect proper wires to the +12VDC, GND, and IR OUT terminals
on the rear of the WL25 as shown in Figure 3.
3. Secure the WL25 into the J-Box using the supplied screws.

APPLICATION WIRING
A typical system, with a WL25, 781ERGPS Power Supply and 283M
Emitters plugged into a 789-44 Connecting Block, is shown in Figure 3:
1. Wire the appropriate leads of the 3 or 4-conductor cable from the
WL25 to the +12VDC, GND, and IR IN terminals on the 789-44
Connecting Block
2. Plug in the 3.5mm mono mini plug from any of the 282, 284, 283
and 286 series Emitters into the jacks labeled EMITTERS on the
789-44 Connecting Block and affix the opposite end to the IR
Sensor Window of the controlled equipment.
3. Plug in the 2.1mm coaxial power plug of the 781ERGPS Power
Supply (not included) into the jack labeled 12VDC on the 789-44
Connecting Block.
4. Plug the AC end of the 781ERGPS power Supply into an ‘un-
switched’ 120VAC outlet.

and 283D Emitters
ADVANCED WIRING CONFIGURATION
WL25 may also be used in conjunction with other Xantech IR Receivers by
simply wiring in parallel on a Connecting Block such as the 791-44 Amplified
Block as shown in Figure 4 below.
1. Connect all IR Receivers in parallel at the terminals of the
connecting block as shown in Figure 4 on the next page.
2. Plug in the 2.1mm Coaxial power plug of the 781ERGPS (or 782)
Power Supply (not included) into the jack labeled PWR on the 789-
44CB.
6
NOTE: Up to 7 IR Receivers may be connected in parallel with a
single 781ERGPS power supply. If more IR Receivers or any
Keypads are required, check total current requirements and increase
power supply current rating accordingly; i.e. 782-00 - 1.2A power
Supply)
3. Plug in the Emitters 3.5mm mono mini plug (282, 284, 283 or 286
series) into the Emitter Outputs on the 791-44.

series, 781ERGPS Power Supply and multiple 283D’s
CAUTION: With any of these systems, be sure the 781ERGPS (or 782-00)
Power Supply is plugged into an un-switched AC outlet. This maintains the
780 system in "stand-by" operation so that power-on commands can be sent
to the controlled equipment.

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”.
