SYSTEM SETUP
After unpacking the CP20, plug in the external power supply and turn on the power switch on the front panel.
The display should light up and display the product name along with the current software revision. If the display
does not light up consult the troubleshooting chapter in this manual.
DMX512
The moving light fixtures are connected to the CP20 via the DMX512 jacks on the rear panel. A standard 5 pin
jack and a 3 pin jack is provided. The two jacks are wired in parallel with pin 1 to ground, pin 2 to data minus
and pin 3 to data plus.
The CP20 is designed to control a variety of fixture types, which accept up to 24 channels of control per fixture.
Fixtures requiring more than 24 channels can be controlled by using 2 or more consecutive fixture addresses.
The CP20 outputs 512 DMX512 channels. You can connect more than 24 fixtures but some will have to share
channels and will operate in unison. There is a soft patch feature in the CP20, which also allows you to set or
change the DMX starting addresses for each fixture. You should also consult your fixtures’ manual for specific
instructions on setting and changing the DMX address.
After the fixtures are connected and the start addresses set, you must next tell the CP20 what type of fixture is
connected at a particular address by making a selection from the fixture library. Consult the "System
Programming" chapter of this manual for further instructions.
When using fixtures that require more than 24 channels, you will have to control the fixture by using more than
one fixture number. For example, a fixture that uses 36 channels will use fixture 1 on the CP20 to control
channels 1-24 and fixture 2 on the CP20 to control channels 25-36.
Once selected, you must then set the starting addresses of the CP20 fixture numbers to align with the DMX512
channels that are controlling the fixture. For example, if you are using fixture 1 to control channels 1-24 on the
moving light and fixture 2 to control channels 25-48, you must soft patch the starting addresses of fixtures 1 and
2 to be 25 channels apart. If this moving light’s start address is set to channel 1 then you would patch fixture 1
to channel 1 and fixture 2 to channel 25. There is also an in-built auto softpatch to help you. Consult the
"System Programming" chapter for more information on soft patching.
