APPLICATION PRECAUTIONS
The VCIR-CFL is designed with special circuitry so that is has great immunity to infrared interference caused
by CFL (compact fluorescent light) and other types of high frequency electronically ballasted fluorescent
lights. Because of this, the following precautions must be taken into consideration when using these special
IR receivers:
1.
The VCIR-CFL is designed to control products that operate with 36 to 42 kHz IR Carriers only!
If you have products that are outside this range, you may need to use a Xantech 780-80 CFL type
instead, along with a 760-00 VC, for instance.
2.
Do not use more than one VCIR-CFL in a given room or area!
If two or more VCIR-CFL's, (or other Xantech CFL friendly IR receiver) receive the same IR signal
simultaneously, the system will not respond.
3.
The VCIR-CFL
(or other Xantech CFL friendly IR receivers)
do not have much improvement in
operation over the standard Xantech IR Receivers in the presence of magnetically ballasted (60
Hz) fluorescent lighting.
You may choose to use the CFL friendly units in most applications anyway, since they will have
superior rejection to other types of IR interference that may exist in the same installation.
4.
The VCIR-CFL will not operate in 2-wire Phantom Power mode.
TROUBLE SHOOTING
1. If the red Talk-Back LED on the VCIR-CFL does not blink when you are sending IR commands from
a remote control, check the following:
•Make sure the power supply is plugged securely into a live 120V AC wall outlet.
•Be sure the +12V, IR OUT and GND leads are correctly connected to the resp12VDC, IR IN
(signal) and GND terminals on the connecting block.
•Check to see that all the emitters you are
using are good, by substituting known good
emitters.
•Models 283 and 286 series emitters will
flash when the remote signal is sent, when
the system is operating correctly; Models
282 and 284 series will not. Use the
Xantech "TEST-IR™" to test for presence
of signal when using the 282 and 284
series emitters.
2. If you are sure the emitters are OK, but the
components do not respond, reposition
the emitter(s). They may not be located
directly over the component’s infrared re-
ceiving "window". Consult the owner's
manual of the component or the manufac-
turer for the exact location of the infrared
"window".
