Switching Between RS-422/RS-485

Switching between RS-422/RS-485 is made with the slide switch (S1) on the OP-03 board.

Connection

The polarity of signals A and B may vary with different computers.

It is not necessary to ground the SG terminal when using a computer without a signal ground terminal.
