E682 Data Interference

[Chris]

Hi Guys,

I'm hoping someone can help here. I've got a San E682 using nutcracker and have 6 strips coming off this with its own data/power line.

However, it appears that the data lines are interfering with the other data lines. I tried some shielded Ethernet cable to try the data and this still interfered with the other shielded Ethernet cable?

Anyone got any advise on what i might be doing wrong? I'm confused as to how a shielded data line interferes with another shielded data lines.

Each runs has about 10/15 meters data / power to fist pixel.

Thanks for help

I think u might add a null pixel . 30-45 ft is pushing the length from e682 to first pixel.

So are you saying you unplug one of the outputs and the problem goes away?  Or is there some other reason you think you're getting crosstalk.  I'd really be surprised if you're getting crosstalk on the twisted pair cables but I guess it's possible.  I run tons of cables together and right alongside power cords so I've been surprised I haven't seen any issues.  The only problem I have is my pixel tree which is 5V strings gets a lot of blue flashes and I haven't taken time to troubleshoot the cause.

Thanks for replys. Hope this extra info helps...

 There is 6 lines for power so each strip has it's own power. I then have 6 lines for data again has it's own data line for each strip.

What i have tried...

Shielded cat cable on strip 1 and shielded cat cable on strip 2 run along the wall together and they interfere move the 2 data cables apart and it seems ok. What i don't understand is How they still interfere with shielded cables.

If i unplug one of the data lines and just run the one data line to 1 strip the data then appears to interfere to the unplugged data line and then that strip powered (but no data line) appears to then do the same as the plugged up data line (strip1). It appears the 'Data' line leaks onto the unplugged one...

Does that make sense :S
