Does 5i25 do RS485 was created by btvpimill
Just trying to figure out if 5i25 can be configured to talk to RS485 stuff directly. Specifically a spindle control. The 5i25 seems like such a capable device, with such awesome features, it seems like doing RS485 from 2 I/O pins must be an option?

There is a FPGA UART device that supports RS-485 line turnaround but it is not fully supported by the LinuxCNC driver so doing things like Modbus would be awkward.

Thank you Peter.
So the easy answer is no, not without a lot of hacking?

Here is an example of the sort of hacking needed, a sample component for a fictional UART-controlled device:

Without _some_ hacking, no.Thank you Peter.
