The Controller Area Network (CAN) was originally developed for automotive applications. It is nowadays a bus system which is widely used in Train, Industry and Building projects.
This bus system allows a very efficient and cost effective networking of modules over a long distance. The CAN hardware and software protocol secure a very stable communication suitable for hard environment projects with high safety requirements.
This “very stable communication” is usually depending on the “work quality” such as the respect of “rules” during the implementation of the CAN network.

CAN malfunctions are often caused by improper use of the bus terminating resistors, by wrong bitrates for the used cable lengths or by a poor cabling.
After years of experience based on different projects in the Train business, the Selectron Systems engineers acquired a huge “Know-How” concerning the implementation of those CAN networks.
In order to help you being efficient in the cabling of your network, those engineers wrote a guideline based on their experience and described the different concepts and points to take care of in such an implementation.
This guideline is available by request at the following email address: support@selectron.ch

Don’t hesitate to ask your questions, the Selectron Systems engineer will be glad to share their knowledge.
