We have 8 groups of between 4 and 7 RGBW luminaires per group. Each luminaire is 230w. The total length of the building is 170m. Each group of luminaires are approximately 25m apart. We were advised by Casambi that it is not a signal issue.
When we use your casDMX not all the lamps change color in a group (some remain white), in other words in a group of 4 – 2 change color and 2 remain static white. We have used one casDMX for each group of lamps. They are installed in a plastic waterproof box approximately 1m from each group.
All luminaires have been bench tested and all work fine when using normal DMX.
If the 4 fixtures are sharing the same DMX Universe that is driven by the same casDMX, then there has to be an issue with wiring or termination.
I can say that 99.8% of DMX issues in the field are wiring related. If you moved a fixture that is not responding to another spot in the DMX wiring chain, does it start to work? If so, then it could be wiring playing with the fidelity of the DMX signal. Our DMX transceiver is good to drive 32 nodes at least, and a fairly long wire run, but wire runs that have long T’s from the main wire run could be an issue.
The casDMX units are operational since two of four fixtures are responding.
Sometimes DMX fixtures that are close to the casDMX (or other DMX generator) seem like they work fine, even with the DMX+ and DMX- wires reversed. As you get away from the DMX generator, this stops working.
