Troubleshooting - BoomToneDJ KUB 1500 RGB User Manual

1. If you are using a controller with 5 pins DMX output, you need to use a 5 to 3 pin
adapter-cable.
2. At last unit, the DMX cable has to be terminated with a terminator. Solder a 120 ohm
1/4W resistor between pin 2(DMX-) and pin 3(DMX+) into a 3-pin XLR-plug and plug
it in the DMX-output of the last unit.
3. Connect the unit together in a 'daisy chain' by XLR plug from the output of the unit
to the input of the next unit. The cable can not be branched or split to a 'Y' cable.
DMX512 is a very high-speed signal. Inadequate or damaged cables, solder joints or
corroded connectors can easily distort the signal and shut the system down.
4. Each lighting unit needs to have an address set to receive the data sent by the
controller. The address number is between 0-511 (usually 0 & 1 are equal to 1).
