7.2.6 Serial line terminations
To set the serial line terminations operate on DIP
2.
The board has two DIP switches used to configure the
serial line terminations (120 Ohm) (Tab. 7, page 23).
Every peripheral that is situated at the end of a line
must be terminated using the appropriate dip-switch
in order to prevent signal reflection and distortion.
Dip-switches 7 and 8 terminate serial lines RS-485-1
and RS-485-2 respectively.
The serial lines are ended with the following dip-
switches: RS-485-1/RS-485-2, dip-switch 7 and 8.
The serial lines are ended with dip-switches.
Serial line: RS-485-1, RS-485-2
Dip-switch: SW 7, SW 8
