There are two 8-pin DIP-switches on the backside of the board at the EX-42032IS. For
each port there is a separate DIP-switch. The 8-pin DIP-switches are for the modes (RS
-232, RS-422, RS-485 2-wire or RS-485 4-wire) and for the signal termination for RX+,
RX-, TX+ and TX- (see picture on page 15). The settings can be set individually for
each serial port. The DIP-switch are responsible for the port 1 (S1) and the second DIP-
switch are responsible for the port 2 (S2). The following images on page 15, 16 and 17
you can see the setting of the mode switch and terminator switch. Additionally the set-
ting of the mode switch are printed on the back of the board.
