CANopen Remote Unit
4.3 CANOPEN NETWORK CONNECTION
The RUW-01 has a green LED to indicate that the interface is powered.
The CAN communication module has a 5 pole plug-in terminal strip (XC3) with
the following pinout:

CAN power supply
The RUW-01 CAN interface needs an external power supply between the pins 1
and 5 of the network connector. In order to avoid problems of potential difference
among the network devices, it is recommended that the network be supplied at
only one point, and that the power supply be taken to all the devices trough the
cable. If more than one power supply is necessary, they must be referenced to
the same point. The individual consumption and input voltage data are presented
in the next
