1.
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.
2.
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 branched or split to a `Y` cable. DMX 512 is a very high-speed signal. Inadequate or damaged cables,
soldered joints or corroded connectors can easily distort the signal and shut down the system.
3.
The DMX output and input connectors are pass-through to maintain the DMX circuit, when one of the units' power is
disconnected.
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).
5.
The end of the DMX 512 system should be terminated to reduce signal errors.
6.
3 pin XLR: Pin 1: GND, Pin 2: Negative signal (-), Pin 3: Positive signal (+)
TROUBLESHOOTING
Phenomenon
* The fixture does not work
* No light out
* No display
* No responding to DMX controller
* Signal error while use DMX
For more information with troubleshooting, pleace contact your reseller
MAINTENANCE
The cleaning of and external optical lenses must be carried out periodically to optimize light output. Cleaning frequency depends on
the environment in which the fixture operates: damp, smoky or particularly dirty surrounding can cause greater accumulation of dirt
on the unit's optics.
Clean with soft cloth using normal glass cleaning fluid.
Always dry the parts carefully.
Clean the external optics at least every 20 days.
* Check main power fuse & power cable connection
* Measure main voltage on the main connector
* Check connection of display PCB
* Replace a new display
* Check working mode setting on display is DMX mode or not
* Check whether the unit be set as SLAVE
* Check DMX address settings
* Check DMX cable and it's connection
* Try to use another DMX console
* Check whether DMX cables be connected well or not
* Check whether the DMX cable has to be terminated with a terminator to reduce signal errors. If
not, please 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 fixture
