LED Pinspot Q4
No Response to DMX
01) Check the DMX setting. Make sure that DMX addresses are correct.
02) Check the DMX cable: Unplug the unit; change the DMX cable; then reconnect to electrical power.
Try your DMX control again.
03) 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.

Return the device to your Showtec
dealer

qualified technician

Install a phase-reversing cable between
the fixtures or swap pin 2 and 3 in the
fixture, that behaves erratically
