5V IR Repeating System:
With the DA-8200 you can control your video devices from any room in the
house. Any or all 8 outputs may be connected to model 2133 IR targets.
Direct your remote control at the IR target and the 2173 IR emitter will
repeat the IR signal to the video devices in the media room.
Normally, the IR emitters are connected to the modulator or 2010 wall
plate. But, if the coax panel is located in the media center, you may chose
to connect the emitters to a model 2184 IR breakout panel.

IR Systems: FAQ
!
!
!
There are two common IR repeating systems. The 12V
system is very versatile and intended for professional installation. The
5V system used by the DA-8200 is easy to use and low cost.
12V and 5V IR targets are
interchangeable. The emitters
interchangeable.
When using a 5V IR system, DC blocks are usually not necessary.

1)
If IR light glows
steadily, there is noise
entering the system.
2)
First
disconnect
the
coax cables from all of the
television output jacks. Find
the source of the noise by
re-connecting cables one at a time until the IR light glows. This identifies that coax
as a noise source. Connect this noisy coax
for the next steps.
only
Remember that
there could be more than one source of noise, so you may need to repeat the
following steps for each coax. Now step 3 will determine which type of noise
problem you have.
3a) Optical noise.
Cover the target with a towel.
If the IR lights stops blinking, you have optical noise.
The target may be pointed at a window, a
fluorescent light or a plasma TV. Reposition the
target so it can’t “see” the source of IR light. If the IR
light still glows, proceed to the next step.
Shade the target
3b) EMI noise:
TV sets are sources of EMI,
electromagnetic interference.
Move the target
away from the TV and try to reposition the target so
the IR light stays off. If the IR light still glows, proceed
to the next step.
Move the target
3c) Conducted noise from the TV.
If the noise is
not optical or EMI, then you have a noisy TV. Some
TV

electrical noise on their
The sensitive IR
detection circuits can be triggered by this noise. Use a high pass filter to remove
the noise. Sometimes a DC block will be a effective filter. The assembly shown
at left is a low cost sure fix for this problem. Create this filter from two different
types of matching transformers. Connect the filter directly to the F-connector
on any noisy TV. Note that any TV can be a noise problem, with or without an IR
target attached.
