Troubleshooting
Symptom
When the keypad is plugged in
there is a loud pop through the
speakers and the keypad does
not work.
My keypad is lit, but nothing
happens when I press a but-
ton.
The amplifier is plugged in and
turned on, but the STAND BY
LED is not lit and none of the
system functions work.
All the keypads change when a
source is selected on only one.
With the keypads plugged in, the
POWER light on the front of the
amplifier will not turn on.
The IR repeater does not proper-
ly control the audio source
equipment.
Probable Cause
Improperly wired Cat-5 cable.
Assigning identical addresses to
more than one keypad usually
causes this.
This is most likely caused by a
blown fuse on the power supply.
DIP Switch # 8 is in the up “O”
position.
One or more improperly wired
Cat-5 cables.
One or more of the IR emitters
are not properly placed over the
IR receiver on the audio source
equipment, or the IR output on
the Essentia does not correspond
with the audio source equipment
you are controlling.
Remedy
Check that you are using the
568A wiring standard. (See
Section I: Crimping Cat-5 Wire)
Each keypad MUST have a
unique address as set by DIP
switches 1-4. (See Section IX:
Setting Zone Addresses)
The fuse is accessed at the back
of the amplifier where the AC
cord plugs in. It requires a 4 amp
time delay fuse.
Place DIP Switch # 8 in the down
“1” position. This will turn off
the source grouping feature.
Make sure the amplifier is
turned on. Test that the POWER
light on the amplifier turns on
when the Network Cable is
unplugged. Next unplug all the
Cat-5 cables from the EZ Port
and plug them back in one at a
time until the bad cable is dis-
covered.
Reposition the LED end of the
emitter on the face of the source
equipment, so it is flashing
directly over the IR receiver.
Make sure that the emitter
plugged into IR Output # 1 is
actually going to source # 1, and
so on for sources 2 - 6.
