My current project is connecting a pktuart -> 6i25 -> 7i84 ->yaskwa rs-485 encoder.
I was able to compile custom hostmot2 firmware with 4 pktuart and 4 sserial components. I have a provisional hal component that is able to send data through 2 pktuart modules that wired together via the 7i84 and send bits back and forth at 2 Mbps which is the frequency that yaskawa encoders function at. The encoders use a 2 wire bi-directional rs-485 protocol so I purchased some mesa 485x1 Rs-485/RS-422 adaptors. I can't seem to get them to work. My testing plan is to get pktuart 0 to communicate with pktuart 1 with 2 of the RS-485 adapters in between them. This will give me confidence that everything is working properly and can then move on to communicating with the yaskawa encoders. I'm not sure exactly how to wire the adapters and I haven't gotten lucky yet with my attempts. Does anyone have a diagram or information on how to use these adaptors? Do I even have the correct approach here?
