RS485 via MESA 7i76e was created by thadwald
HI
Is it possible to get a second serial interface on the MESA 7i76e board? I need to interface a Mitsubishi VFD via RS485 and I have a 7i73 pendent board connected to the serial interface on TB3.

You would need to add an additional RS-485 interface.
(either an existing daughtercard (7I74,7I78,7I85S,7I85,7I88,7I89
or a simple adapter with a a single RS-485 chip like a SP491 (like a mesa 485x1))

How did this work out? I also have a 7i76e and are sick on my USB-RS485 converter that resets itself sometimes in the middle of a program... Might be interference from my HY VFD. Want something more robust.
pktUART bin file is not available from MESA. Do not really know if this is the way to go or if there are something simpler?
