Hi
I am having a struggle getting my second differential receiver board working.
I have only just decided to get it tested and ready after purchasing it quite some time ago.
I am using a Kulp K8-PB controller which works fine and is connected to its own 5v power supply.
My megatree is about 15 metres away so I have set up an enclosure with 2 more 5v power supplies and 2 power distribution blocks.
Each block and differential receiver is connected to 1 of the power supplies.
The issue I am having is that any string plugged into any port of receiver 2 just has the first led lock on green.
When testing I switched the ethernet cables and the same 8 ports still work and the led is still locked green.
The working board is a v2.0 and the non working board is v2.1.
I thought it may have been a common ground issue so I wired from the Kulp controller ground output to the other 2 power supplies ground outputs but got the same result.
I know the string is testing fine because when I connected to to an sp105e tester it works and if plugged into one of the working ports on board 1 they also still work.
So I don't think it's the data output or software based and I am at a loss as to why it isn't working.
Have attached photos of my outputs in FPP and Xlights which have been rendered and uploaded.
Anything else I can try? The ld01 on board 2 is lit and there it measures 5.05v at the input connectors.
