I have a stepper motor that I am trying to control with an Epson robot. I can get the robot program to give the stepper string commands using the PC's COM port (and it responds as expected) but I cannot figure out how to receive messages from the motor. The stepper is RS458. I have an RS485 to USB converter to the PC. The Epson software, however, only lets me configure a COM port as an RS232 port. Does the protocol matter once it is converted to USB?
Is R232 > USB > RS485 possible or is that my problem?
I am pretty new to automation and communications.
