CABLE CONNECTIONS
291’s 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-terminal block on the CB12 as shown in the figure
below.

SLEEVE +12VDC
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.
REMOTE ROOM APPLICATION
The CB12 Connecting Block, supplied with the Hidden Link IR Receiver, has
a three terminal input strip for connection of external infrared receivers
should you wish to control your equipment from other rooms.
• The terminals are marked V G S. (V = +12V, G = Ground, and S = IR
Signal).
• Make connections as shown in the figure below. Run a 3-conductor
cable (24 to 18 gauge wire, stranded or solid) from each remote
room to the VGS terminals of the CB12.
• When you use a Hidden Link IR Receiver in a remote room, do not
plug in a power supply or use the “OUT” jack in the CB12, as shown
in the figure below.
• You may use more IR receivers, connected in the same manner, up
to a maximum of 12.
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.
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 Hidden
Link IR Receiver.
2. You can confirm the source of the interference by temporarily turning
off TV sets, isolating the Hidden Link IR Receiver from all sunlight
and turning off all lights, light dimmers and Infrared security systems.
