Dinushan Paranavithana Posted February 18, 2020 Share Posted February 18, 2020 I'm looking for a way to control this DMX engine (LEH-4091 DMX) using RS232 Engine. Has anyone tried controlling this unit? http://www.minar.com.cn/en/content/?263.html Quote Link to comment Share on other sites More sharing options...
lippavisual Posted February 18, 2020 Share Posted February 18, 2020 Haven't tried this particular unit, but should work the same as any other. You would just be connecting Channels 1-4 for RGBW control. Everything else wouldn't be compatible with the DMX Engine driver. All color control, speeds, etc. would be created on the Engine.

Hi @lippavisual Have you tried anything for pool RGBW lighting? Quote Link to comment Share on other sites More sharing options...
lippavisual Posted February 24, 2020 Share Posted February 24, 2020 Unless it's a dumb light that is DMX compatible, you won't have any luck with pool lights. They typically use 120V and the On/Off switch toggles the colors/scenes. Quote Link to comment Share on other sites More sharing options...
Kevin L Posted February 24, 2020 Share Posted February 24, 2020 That DMX engine you linked would work fine using the Domaudeo DMX driver + the Engineering Solutions RS232 DMX Box Quote Link to comment Share on other sites More sharing options...
Dinushan Paranavithana Posted February 28, 2020 Author Share Posted February 28, 2020 Hi @Kevin L I have tested the DMX driver + Engineering Solutions RS232 DMX box with Colorbeam lighting and American Lighting and they both work without any issue. However, I can't get the LEH-4091 to work. I'm not sure whether we need to do some additional configurations. If you know anything about this, please advise. Thank you.

Kevin L Posted February 28, 2020 Share Posted February 28, 2020 I would suggest you reach out to the manufacture of the light and ask them how to enable and control it via DMX channels. Quote Link to comment Share on other sites More sharing options...

Dinushan Paranavithana Posted March 4, 2020 Author Share Posted March 4, 2020 Hi @lippavisual & @Kevin L It's working now. Earlier, I was using the DMX RGB Dimmer in composer, which has 3 sub channels to assign red, green and blue. I then enabled the RGBW management option and linked the additional DMX dimmer for the white channel. This worked well for American Lighting LED strips and Colorbeam recessed lights but not for this DMX engine (LEH-4091). Finally, I used individual DMX dimmers for the respective channels after finally getting the user manual from the manufacturer. We need to add an additional channel (Channel 6) for the dimmer to work. Otherwise It would not turn on. CH1:Red (256 level) CH2:Green (256 level) CH3:Blue (256 level) CH4:White CH5:Speed (256 level) CH6:Dimmer (256 level) CH7:Strobe/Program Speed CH8:Preset Program I'm sharing the datasheet for anyone interested.https://www.dropbox.com/s/i3uf1rl0fjdpfvy/LEH-4091 DMX Datasheet.pdf?dl=0 Quote Link to comment Share on other sites More sharing options...

I will add that you can enable the "Real" master channel from the RGB Dimmer and it will allow you to use the Channel 6 as a master dimmer, so it will turn it on automatically when you play with the RGB slider, it will also use it for brightness control instead of trying to simulated the brightness using the RGB channel, that work much better. Also the ColorChanger and Effect switch both support light fixture with brightness channel natively. Quote Link to comment Share on other sites More sharing options...
