Hello, can anyone help me get v/h correct when creating a link with these two radios? Specifically, on the F400c which way around do the ch0 and ch1 go? Is ch0 V or H to link correctly to an F425?
50/50 is not good enough odds when takung my current luck into consideration.
Thanks!

It doesn’t make any difference. The receivers have no idea what V or H polarity they are connected to. Each receiver just receives one polarity much stronger than the other polarity, so they decode the stronger stream each. The other receiver decodes the stream it receives the strongest, and then the 2 streams are combined, properly formatted, and delivered to the ethernet or fiber port.
