TROUBLESHOOTING &
SERVICE
There are no user serviceable parts inside the CP-3. Any internal problem should be referred
to a qualified service technician.
CLEANING AND MAINTENANCE
As with any type of control console, keep drinks away from the CP-3. If you need to clean the
front panel use a soft cloth. If necessary you can spray a small amount of glass cleaner on the
cloth. Do not spray directly on the CP-3. Do not spray electronic cleaners into the faders.
Refer fader and switch maintenance to a service technician.
POWER SUPPLY
If the CP-3 will not turn on, check the external power supply. There is no fuse inside the CP-3.
If the power supply should ever fail or become lost, only replace it with a U.L. or CE approved
one with the same voltage and power rating. The supply must provide 9 volts DC at 500 mA.
The plug has a 2.5 mm hole with + voltage at the center.
DMX-512
(This unit complies with the USITT DMX-512 Standard of 1990).
If your fixtures are not responding correctly to the CP-3, check the dipswitches on the fixtures.
Please refer to the instruction manual for the fixtures to make sure they are set properly. If your
fixtures are not responding at all to the CP-3, still check the dipswitches on the fixtures but also
check your cabling and connectors, for open circuits or short circuits. For example, never
connect the shield of your DMX cable to the shell of the connector. If you are running long lines,
you will need to terminate the last fixture in your DMX512 chain with a special termination plug.
If you don't have one you can make one by taking a 5 pin or 3 pin male XLR plug and soldering
a 120 ohm resistor between pins 2 and 3. Plug this into the unused signal output connector on
the last fixture in your DMX512 chain. Bad cable or incorrectly wired cabling accounts for 90%
of the problems in a system.
Problems are resolved by eliminating one problem at a time. So start with one cable connected
to the first fixture and check this out first. Once you have the first fixture operational move to the
