1. Введение
1.1 Обзор
GCAN-212 is a customized converter with one or two CAN bus interfaces. The converter has integrated CPCI interface, so it can be used to IPC which communicate through CPCI bus.
The GCAN-212 can customize multiple communication interfaces such as: Ethernet, Serial bus, USB, and so on. Users can use the customized converter into their own system and connect it to CAN bus.
Note: The following chapter and parameters are all customized to CANopen-Ethernet.
