Dose rmc75s support serial RS-422?

This is a dual - axis device. I want to use RMC75S to receive two command positions sent via RS - 422 at a baud rate of 460800, every 5ms. Does RMC75S support Serial RS - 422 ? If RMC75S doesn’t support RS - 422, I’ll opt for RMC75E. Could you recommend an adapter to convert RS - 422 to Modbus TCP or other supported signal types?

The RMC75S serial ports do not support serial RS-422 communications. The RS-232 monitor port only supports RS-232, and the second port supports RS-232 and RS-485 (but not both simultaneously).

In order to possibly recommend a converter, I need more information. RS-422 defines the wiring and voltage levels on the wire. What protocol is being used over the RS-422?
