3.6.2 Bus termination resistor
The first and last modules on a DeviceNet network must be terminated with
a 120
Ω
bus termination resistor. This resistor needs to be connected
between CAN_H and CAN_L.

3.6.3 Max. cable lengths
The maximum bus cable length depends not only on the data rate, but also
on the type of cable being used. The following cable types are permitted:
•
A so-called “Thick Cable”,
•
a so-called “Thin Cable”,
•
a so-called “Flat Cable”,
