For the host connection of the MA 255
i
, the ready-made KB DN/CAN-xxxxx-Sx cables
are preferred, table 14.5 "Bus connection cable for the MA 255i" on page 80.
Notice!
Ensure adequate shielding. For the devices and ready-made cables offered by Leuze
electronic, the shield is on PIN 1.
7.4.1
Termination of the DeviceNet
The last physical DeviceNet participant must be terminated with a terminating resistor (see
