plasmadrive Posted December 24, 2014 Author Share Posted December 24, 2014 I wonder if it might be a bad solder point. With temperature changing it might just be enough to open or close the connection...Two in a row is a bit of a odds breaker for a solder joint.. Not impossible however.

a31ford Posted December 29, 2014 Share Posted December 29, 2014 (edited) Plasma, for what it's worth... read this post, http://forums.lightorama.com/index.php?/topic/8769-some-channels-come-on-and-stay-on/?view=getnewpost and try the RS485 terminator set like the ones I show pictures of in that post... If you get a chance, do some research on the RS 485 protocol, you will find tons of info on creating a balanced or terminated 485 network. EACH segment of cable (before the ELLS, and after, as it can be any segment that has the noise) this would be the reason they test fine when you test later......

plasmadrive Posted December 29, 2014 Author Share Posted December 29, 2014 Hey Greg, Not a termination issue. Not a noise issue.. Been thru all that.. It is not a reflective problem.. What ever caused these two ELLs to stop working is unrelated to the RS485 network. Craig Link to comment Share on other sites More sharing options...

plasmadrive Posted December 30, 2014 Author Share Posted December 30, 2014 The only thing RF wise in my display is an Arduino with a nRF transmitter. However... I doubt that is of issue. It would not be able to kill one and stop the other from receiving data. As well, ,the only thing I did to fix it was to put another in their place. Same mounting place. Been working fine ever since. I still have to try the two that failed in real application again since they work on the HU... When I find out.. IF I find out.. I will post.
