8.14.5 DIP4 configuration
This DIP is set following the inverse
procedure compared to those previously
performed. When the switch rocker is up
it represents the value 0 (OFF). When the
dip-switch rocker is down it represents the
value 1 (ON).
The board has two switches used to configure the
serial lines terminations (120 Ohm).

Every unit that is situated at the end of a line must be
terminated using the appropriate switch in order to
prevent signal reflection and distortion.
Switches 1 and 2 terminate serial lines RS-485-1 and
RS-485-2 respectively.
