There is an eight 8-pin DIP switch next to the connector for changing the
operating modes, enable/disable terminator and the bias for transmitter and
receiver signals.
1. Mode Settings:
The DIP switch has 8 pins, the first 3 pins (M0, M1, M2) are for mode settings
(RS232, RS485-2wire, RS485-4wire or RS422 modes), pin 4 (TERM) is to enable or
disable terminator. Pin 5 and 6 (T+, T-) is for biasing TX+ and TX- signals. Pin 7
and 8 (R+, R-) is to enable or disable bias for RX+ and RX- signals.
Note: Pin 4 to 8 are designed for RS422 and RS485 only and should be
set to OFF when you are setting the port to RS232 mode.

Pin 5 to 8 of the DIP switch are to enable (ON) or disable (OFF) the 4 bias
resistors for TX+, TX-, RX+, RX- signals respectively. Please note that you have to
set them to OFF if you are setting the port in RS232 mode.
