CANOPEN CONNECTION
Pin Signal Description
2 CAN_L CAN low bus line
3 CAN_GND
7 CAN_H CAN high bus line
CANopen is an higher-layer communication protocols based on a
CAN seria bus system.
For the connection using a cable with a twisted pair differential and
common return in accordance with ISO 11898. The length of the
bus is limited by the speed of communication chosen according to
the following table:
Bit Rate Max. Bus lenght
1 Mbit/sec 25 m
500 Kbit/sec 100 m
250 Kbit/sec 250 m
125 Kbit/sec 500 m
<=50 Kbit/sec 1000 m
The CAN line must have the resistance of 120Ω termination.
The reference CAN_GND must be connected to earth at one point
of the line.
The cable can not be channeled with power cables.
For the configuration of the card is available ESD file that must be
installed in the master.
