You all have been great providing your knowledge and suggestion. I really appreciate that you all take the time to monitor this and lend a hand. Thank You

Thanks Sunray - I am saving SLAV mode, and then going to the DMX channel, and pressing enter. I do not think SLAV mode has anything to do with it, but it was a suggestion here. DMX in/out are directly connected. Host/Master mode on fixture 1 does not control SLAV mode on 2nd fixture My primitive tester (LED+resistor - it works when connect to control desk) does not show signal across any pins. Switch roles of fixtures - same result. Hard to believe, but I think alistermorton suggestion that the transceivers in all of these fixtures may have been damaged in a single event, might be correct.

Thanks James - Yes. I made sure it was on the A001 menu

ok - just again tested two bad fixtures set (A001, SLAV) separately. Tried polarity in both positions - no response from fixture

@YNOT - it does now. I needed to make a drawing 🙂 but I see your point and understand

A fair point alistermorton I did not think about that - but yes, they were all in the same DMX chain for a regional bands show. I was told they got rid of them because they were heavy (and they are), but perhaps that is the issue. Again, I would think since it is passing data to DMX out, that would not be the case - but I certainly could be wrong.

I am referring to the wiring - polarity, not in/out/ My statement was trying to diagnose if the fixture was wired with reverse polarity. And I was saying, if the 1st fixture was reverse polarity then any fixture connected to its DMX out should not work. In my case, the fixture connected to the DMX out does work, so I should be able to assume that the polarity is not reversed for the fixture in question

Sorry - I did not type what I was thinking, I meant the light on the DMX out would NOT work IF the fixture's polarity was reversed, and since that 2nd light does work, I can assume the polarity is wired correctly. The changes to the address (and other settings) are stored after pressing enter, and they do survive power cycle. Just tried 2 different fixtures, one at a time, on a known working Obey 70. Set A001 and Slave mode, verified the settings survive power on/off. The fixture does not respond on any channel

Thanks for all the suggestions. Right now this is extremely simple setup to try to get it working - so I have been working with one or two lights, no splitters, etc. and all new DMX cables. I can change the channels, and also values G000-255 - which act as you would expect and remain saved when the light is power on/off. I have also tried the polarity switch on the back of the controller when the light was connected by itself. I have done the 12-Ch on a known good console, setting fixture to A001 - and have tried many combinations of channel values, the fixture does not respond at all. I really do appreciate all the suggestions - I have only tried 4 of the 8 fixtures, but they all behave the same way, which is hard to believe. If the polarity on the DMX in was reversed, then I would not expect the fixture I have connected to the DMX out to work - and it does. Is this the wrong assumption for me to make?

Hello all. I am new to DMX lighting and happened to be given a number of unbranded 18LED waterproof lights. I am unable to control them from a known working DMX controller. The fixture does not have a menu config for a D-channel that all other DMX light I have come across have, it does have an option for A001-512 which I assumed was the same thing (address) - however they do not respond on any channel. The light do work fine setting RGBW and even the internal programs, and I know DMX signal is at least passing through the light, tested by using the DMX out of the fixture to another. I thought perhaps it was just a bad fixture, but all 8 of them do the exact same thing. I am hoping someone has seen this before and can help get these light into a mode where they listen like normal DMX fixture. (Is there a startup key combination? Is there a difference between A001-512 and d001-512?) Available Menu Options: A001-512 P01-40 So01-02 Host-Slave r000-255 g000-255 b000-255 u000-255 u.000-255 I realize this is a tall order, not knowing the manufacturer/brand, model - but perhaps someone has come across this before.
