TROUBLESHOOTING
This short guide is meant to help and try to solve simple problems. If they continue and the device cannot operate,
please, don't try to repair it by yourself, return the device to your MARK dealer.
If a problem occurs, carry out the following steps in sequence until you find a solution to the problem. If finally, the
unit operates properly, don't continue with the next steps. If the light effect does not operate properly, refer servicing
to a technician.
No Light
Response: Suspect two potential problem areas: the power supply and the LEDs.
1- Power supply. Check that the unit is plugged into an appropriate power supply.
2- The LEDs. Return the device to your MARK dealer.
3- Check if the fuse is not blown, if it is, change it with one that keeps the same technical features. If once the
fuse is ok the device again blows it, please, don't change it again, contact the MARK technical service.
4- If all the above appears to be OK, plug the unit in again.
5- If you are unable to determine the cause of the problem, do not open the device, as this may damage the
unit and the warranty will become void.
6- Return the device to your MARK dealer.
No DMX
Response: Suspect the DMX cable or connector, a controller's wrong function, or a light effect DMX card error.
1- Check the DMX setting. Make sure that DMX addresses are correct.
2- Check the DMX cable: Unplug the unit; change the DMX cable; and then reconnect to electrical power. Try
your DMX control again.
3- 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.
DMX Connection
When fabricating your own cables, always observe the illustrations on this page. Never connect the shielding of
the cable to the ground contact of the plug, and always make certain that the shielding does not come into
contact with the housing of the XLR plug. If the shielding is connected to the ground, this can lead to short-
circuiting and system malfunctions.
To prevent system errors, the last device in a DMX chain needs to be equipped with a terminating resistor (120
ohm, 1/4 Watt).
