Mac250 and Strand 300

[gingertom]

Ok, I've been a good boy and done the google thing, but am still having issues!

This is the sketch:

I'm running out of Universe 2 on the 300 into a ChromaQ 8way PSU, then out to a daisy chain of 5 Mac250s with a terminator in the final unit. The problem is the last 2 in the chain are sat "twitching" slightly on P & T. I've tried bypassing earlier units in the chain to see if thats the issue, I've checked they're all sat in mode 4 etc., I've tried swapping out the cable runs, and am now hitting a bit of a wall.

 

Does anyone have any ideas? Is there a known weakness in this set up, e.g the ChromaQ PSU puts out dirty mux?

 

Any thoughts gratefully recieved!

Just out of interest, try pulling the terminator out. Had that with VL5s not dimming correctly when terminated but fine with no terminator.

I had a go at that, but the last 2 on the string went home, and refused to do anything at all!

Any thoughts gratefully recieved!

Do they twitch when plugged straight into the 8 way?

I'm confused. You've described 50% of a good troubleshooting procedure, and then stopped short of bypassing the Chroma-Q PSU, and instead asked us about it? Why not unplug the Chroma Q and see? Also try plugging up the macs in a different order. Is it those two units, or whichever units are last in the chain?

 

Any hope of putting the Chroma Q last in the circuit?

Thanks for the responses. I was asking for suggestions to see if there were known problems or similar experiences. My fault finding is normally bob on, but I have limited access to the venue, and was hoping someone might have one of those nuggets of wisdom that turn up frequently here!
