CAN physical layer specifications publicly available
The CiA 103 specification describes a framework for CAN highspeed networks used in explosive environments. It has been developed in cooperation with CPAC (Center for Process Analytical Technology) at the University of Washington, Seattle (USA). The intrinsically safe CAN physical layer specification requires 3,3-V transceiver chips and microcontrollers with onchip CAN modules. Sensor manufacturers supplying for gas chromatographs have implemented the framework firstly. Devices compliant to CiA 103 received already approvals for hazardous area class 1 by North American and other authorities.
The specifications are downloadable from CiA's website (www.can-cia.org).
