Hi Maarten, thanks for replying.
No, no changes at all. One day it just quit and I got the dreaded phonecall
Since posting here i figured a few more details:
After a power on-off reset of the Elite only (can not reset the receivers and lights part) all is normal for a while, ranging from 20min to hours. Then i get the phonecall
I got the chance to actually see how it fails. Some receivers start losing signal first, the lights become flakey, then more receivers lose signal and after a while all receivers lose signal. (The DMX receiver behaviour is set to go dark in absence of DMX signal).
The Elite does NOT lock up, the track # display changes from the buttons.
I tested the DMX pair and ground for shorts, none found.
I powered the Elite from a separate power adaptor and the voltage was verified as steady 4.97V
I have a sneaky suspicion that the time interval after the reset 'till bad things start happening has been decreasing lately, this should be good news actually, maybe it comes to a point when the problem, whatever that is, will become possible to replicate on my test bench.
Of course, the customer is all over my back, but they are patient so far.
Any ideas what to check/try? LOL
