CiA Draft Standard 301<br />
version 3.0<br />
Both ends of a <strong>CANopen</strong> network need to carry a terminating<br />
resistor to minimise line reflexion and, consequently,<br />
to improve the safety of data communication.<br />
Terminating resistance: 120Ω / ¼ W<br />

If you enconter problems when first starting the bus, the<br />
first thing you should do is to measure the resistance<br />
between CAN_L and CAN_H. The resistance should be<br />
approx. 60 Ω. If it is out by too much check whether the<br />
termination resistors have been put in properly.<br />
