01) Check the DMX setting. Make sure that DMX addresses are correct.
02) Check the DMX cable: Unplug the device; change the DMX cable; then reconnect to electrical
power. Try your DMX control again.
03) Determine whether the controller or the LED Dim 12 is at fault. Does the controller operate properly
with other DMX products? If not, take the controller in for repair. If it does, take the DMX cable and
the LED Dim 12 to a qualified technician.
