2.2.2 Wiring for 32DP-IF and Profibus-DP Network
To connect the 32DP-IF to a Profibus-DP network use only the Profibus connectors and
shielded twisted-pair cable complying with EN50170.
Please use terminating resistors and Profibus connectors as shown in the DP-master manual
and Profibus connector manual.
The 32DP-IF does not have a terminating resistance built-in.
