Title: Onboard RS-485
Post by: EDurako on September 19, 2019, 03:42:55 PM

Has anyone had any luck with those new EA9-RHMI headless Cmores? I'm trying to use the 3 wire RS-485 port on it and the BX-DM1E-M. I can't get it to talk. I have a 121 ohm resister in the end and I have also tried it without. The baud rates and other parameters all match. The ports flashed for a while and were talking. Now they are dark and I can't figure out whats up.

What are you using for wire? 

Have you tried swapping + and -?

Are you sure that your port settings match on C-more and Do-more?
