This troubleshooting guide is meant to help solve simple problems. If a problem occurs, carry out the steps
below in sequence until a solution is found. Once the unit operates properly, do not carry out following
steps.
If the light effect does not operate properly, refer servicing to a technician.
Response: Suspect two potential problem areas: the power supply or the LEDs.
1. Power supply. Check that the unit is plugged into an appropriate power supply.
2. The LEDs. Return the Cameleon Bar to your Showtec dealer.
No Response to DMX
Response: Suspect the DMX cable or connectors, a controller malfunction, a light effect DMX card
malfunction.
1. Check the DMX cable: Unplug the unit; change the DMX cable; then reconnect to electrical power.

2. Determine whether the controller or light effect is at fault. Does the controller operate properly with
other DMX products ? If not, take the controller in for repair. If so, take the DMX cable and the light
effect to a qualified technician.

No light
Probable cause(s)
No power to the fixture
The controller is not connected.
3-pin XLR Out of the controller does
not match XLR Out of the first fixture
on the link (i.e. signal is reversed).
Poor data quality
Bad data link connection
Data link not terminated with 120
Ohm termination plug.
Incorrect addressing of the fixtures.
One of the fixtures is defective and
disturbs data transmission on the link.
3-pin XLR Out on the fixtures does
not match (pins 2 and 3 reversed).
The power supply settings do not
match local AC voltage and
frequency.
LEDs damaged

Remedy
· Check that power is switched on
and cables are plugged in.
· Connect controller.
· Install a phase reversing cable
between the controller and the first
fixture on the link.
· Check data quality. If much lower
than 100 percent, the problem may
be a bad data link connection, poor
quality or broken cables, missing
termination plug, or a defective
fixture disturbing the link.
· Inspect connections and cables.
Correct poor connections. Repair or
replace damaged cables.
· Insert termination plug in output jack
of the last fixture on the link.
· Check address setting.
· Bypass one fixture at a time until
normal operation is regained: unplug
both connectors and connect them
directly together.
· Have the defective fixture serviced
by a qualified technician.
· Install a phase-reversing cable
between the fixtures or swap pin 2
and 3 in the fixture, that behaves
erratically.
· Disconnect fixture. Check settings
and correct if necessary.
