IR TROUBLESHOOTING GUIDE
NOTE: Due to the many variables in a given installation, 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, etc.... Therefore,
your countermeasures for a particular job will range from nothing at all, to any
combination of the solutions listed below.
IR Receivers: Model #'s DL, HL, ML, and WL series
Symptom #1:
DIM or NO Talk Back LED during IR Reception or reduced operational range
Cause
1. Weak Batteries in Transmitting
Remote.
2. Bad Emitter or no emitter plugged
into connecting block.
3. Signal wire between IR Receiver
and the Connecting Block is
open.
4. Power Supply not putting out
proper voltage.
5. Output from the IR receiver/
connecting block is connected to
a high impedance IR input jack on
a component.
6. IR Receiver is inoperable.
7. (XTRALINK Only) RF Amplifier is
being used on same COAX Line
anywhere between the Coupler
(CPL94) and Injector (INJ94).
Solution
Replace batteries.
Test emitter and verify wiring.
Recheck wiring.
Verify supply is a 12VDC regu-
lated supply reading between 11.5
to 13VDC under load. Should be
using Power Supply Model PS12-0.5
(12VDC Regulated, 200mA) or PS12-
1.25 (12VDC Regulated, 1.2A)
If you are using a passive connecting
block, such as a 789-44, and the sys-
tem is not working, try the amplified
connecting block, model 791-44. Put
one of the small plastic case jumpers
supplied with the block on the pins
next to the emitter jack. This will pro-
vide the IR-in jack on the component
with a hotter signal.
Replace Receiver.
Need to use a Bypass Kit (model
BYPASS94 Kit) to route the IR control
signals around the amplifier(s).
