Instructions
1.
Verify Power Supply
With a Multimeter, measure the DC Voltage of
the supply while it is connected to the Connecting
Block. Put the Negative lead of the meter on the
terminal marked GND and the Positive Lead on
the terminal marked 12VDC (or V). You should
get a reading between 11.5VDC and 13.0VDC.
If not, remove the supply from the Connect-
ing block and measure again this time directly
on the 2.5mm Coaxial plug. If it reads between
11.5VDC and 13VDC, power supply is most likely
good. Reconnect to the Connecting Block and
proceed to step 2. NOTE: In most cases this will
indicate the supply is good but in some cases the
supply can still be bad (i.e. reads good when not
plugged in but may not be able to handle the cur-
rent load of the system.)
2.
Verify Emitter.
(283D or 286D
Blink Style ONLY)
Remove the power supply from the connecting
block and all Emitters from the output. Place a
jumper wire on the connecting block between IR
and +12v. Reconnect the Power Supply and one
emitter. The Emitter should Light bright and solid.
Repeat for all emitters.
3.
Verify Emitter.
(282M or 284M
NON Blink Style)
Use a diode tester to verify proper Emitter opera-
tion. Remove Emitter from Connecting Block.
Place the Positive Lead of the tester on the TIP of
the Mono Mini Plug and the Negative Lead on the
Shield of the Mono Mini Plug. Meter should read
a voltage. When the leads are reversed (Positive
lead on Shield and Negative lead on TIP) you
should not get any voltage reading at all.
4.
Verify IR Receiver.
Remove the power supply from the connecting
block and all Emitters from the output. Place a
jumper wire on the connecting block between IR
Signal and GND. Reconnect the Power Supply.
With a known good hand-held remote, shoot a
constant IR Command at the receiver and verify
the TB LED on the Receiver lights.
