By lowering the baud rate you're now allowing device B (and SERIN2) twice the time to receive the bits and assemble the byte.
That's probably what's helping a lot more than any line noise issue.

Tumbleweed, I had very strong suspicions that the issues were in the communication lines. I changed the Baud rate from 19200 to 9600 and I haven't got anymore wrong data at the receiver. I remember...
Ioannis, yes I'm doing data validation checks all the time. The first byte of the array is always 174. If this condition is not met, then the reading is discarded.
There is no much code to show here. I know device A is sending the right data because I can see it with a logical analyzer. I know device B, like 1 out of 5 times, is reading some bytes wrong because...

Re: SERIN2 Receiving Wrong Data
There is probably a little bit of both. I did a search in the forum, but couldn't find anyone having the same issue.
