Figure 1
1. 12VDC Jack – Provides 12 volt DC power to IR-CB2
via a regulated power supply.
2. IR Emitter Outputs – 3.5mm jacks provide output for
either single or dual low-level flashers.
3. 3-30V AC/DC Status – 3.5mm jack provides
system status to sensors/keypads via a 12V power
supply attached to a switched outlet on the system
receiver or a 12V trigger output.

3
4. 12V Output – When 12 volts is detected at the
status jack (#3) the 12V output jack will output
12V/200mA DC. This is useful for triggering
external devices and system automation.
5. Status/IR Confirmation LED – This LED performs
two functions: (1) it provides a visible indication of
system status via a green LED and (2) confirms the
reception of IR data via a blinking blue LED.
6. Emitter Hi/Lo switch – Setting these switches to
the appropriate position allows you to connect
either a high output flooding emitter (IR-E1HO)
or low output microflashers.
7. Sensor Inputs – Removable quick connect sensor
plug for connection of IR sensors to the system.

PREPARING FOR INSTALLATION
The IR Receiver cables, emitter cables and the 12V
DC power supply cable must all reach the proposed
location of the IR-CB2 connecting block. Mark the
cables with Wire Labels, describing where the
cables originate from, rather than where they will
terminate. Locate a local un-switched AC outlet to
be used to power the IR-CB2 power supply.
Tools Required
n1/8" Slotted screwdriver nWire stripper
nWire labels

INSTALLATION
1. Select an appropriate location for the IR-CB2
2. Run all the necessary wiring to the IR-CB2. Label
the wires for future reference.
3. Plug the supplied 12V DC power supply into the un-
switched AC outlet.
4. Plug the 12V DC power supply connector into the
IR-CB2 socket marked POWER.
5. After verifying that the AC outlet works, unplug the
power supply connector.
6. Strip 1/4" of insulation from the end of each CAT5 wire.
7. Locate the Snap and Lock Connectors and remove
them if they are plugged in.
8. Use a small flathead screwdriver or your thumb to
raise the locking tabs, exposing the holes on the
connectors.
9. Insert each wire into the appropriate hole and
snap down the locking tabs.
10. Insert the smooth side of the connector plug into
the smooth side of the IR-CB2 socket.
11. Connect the emitters to the emitter outputs.
12. Plug the 12V DC power supply connector into the
IR-CB2 socket marked POWER.
See installation diagram.
Power Status
You can send a Power Status signal to all JobSite
IR Receivers by connecting a 12V DC power supply
from the switched AC power outlet of the
preamp/receiver to the status input jack of your
IR-CB2. Any 12V DC power supply with a minimum of
100mA current capacity can be used.

Test your IR Repeater system by
following three principal guidelines:
1. All components can be operated: Test all of your
remote controls for all of your equipment.
2. Operation is consistent: Agood test is to
repeatedly step from Pause to Play with your VCR,
CD, DVD, or Tape player remote control. Operation
should be identical to standing in front of the
component with the remote control pointed
directly at the Receiver window.
3. Maximum Range between the Remote Control and
the JobSite IR Receiver is similar to the maximum
range between the Remote Control and the A/V
component’s IR Receiver: Typically a remote
control with two batteries will have a 15 to 20 foot
range and a remote with four batteries will have a
20 to 30 foot range.

TROUBLESHOOTING
Bad Connections or Wiring:
If the connections or wiring are wrong, loose,
shorted or open the system will not operate properly.
The symptoms could include: Power LED flickers or
is off, IR Test LED is continuously flickering or on
without any remote control use, intermittent
operation or no operation.
Solution:
1. Test your power supply connections.
2. Test your receiver connections.
3. Test your emitter connections.
4. Test your cable for shorts and opens.
IR Saturation:
Sometimes the emitter output can saturate the IR
receiving window of a component. When this
occurs, the IR command will not be executed. This
can occur on an intermittent basis when there is a
Plasma TV in the system.
Solution:
1. Remove the IR Blocking Cover if you are using one.
2. Turn on the Plasma TV, because this may be
contributing to the problem.
3. Relocate the IR emitter approximately 1/2" away
from the IR receiving window.
4. Some experimentation will be required to
determine the best location for Emitter.
5. Test system. Do not use an IR Blocking Cover if a
component is sensitive to IR saturation.

7
Optical or Electromagnetic
Interference:
Direct sunlight, neon signs, television sets, light
dimming controls and other sources of
electromagnetic fields can induce noise and
interference into your IR repeater system. Symptoms
can include: flashback LEDs continuously flickering
or on without any remote control use, poor range,
intermittent operation or no operation.
Solution:
1. Move the receiver or the receiver cable away from
the EMI source or move the source of the EMI
away from the Receiver or the cable.
2. Connect the receiver’s GND terminal to true earth
ground (if this isn’tfeasible use the main system
unit’sGND terminal).
Optical Feedback Loop:
If you have an IR receiver in the same room as a
emitter, and you have some low-level noise or
interference, an optical feedback loop can occur
which will interfere with proper operation. Symptoms
can include: poor range, intermittent operation or no
operation.
Solution:
Replace the IR-E1HO “flooding emitter” with IR-E1 or
IR-E2 Emitters and cover all emitters with the
supplied IR Blocking Covers.
