ON the ab7702 the install guide says pin 13 in 485B and pin 14 is 485A.
does this mean pin 14 485A is for TXRX+ and pin 13, 485B is for TXRX-
?
Hello,
In general, I think B is + and A is -. The issue is that the nomenclature is not standardized, however this is how it should be based on past experience.
Best regards,
