Subject: RS485 channel A should be pulled up and B down for fail-safe mode.
X-Git-Url: https://privyetmir.co.uk/gitweb.cgi?a=commitdiff_plain;h=ba459e3aeb4d04e035b88f96979cda2ef8e604a2;p=electronics%2FUSB-RS485-Adapter

RS485 channel A should be pulled up and B down for fail-safe mode.

The previous version has this swapped and we get a spike at the end of
each packet as the lines adjust to the non-driven state.
