The IF-CAN-BC-Converter will enable the user to connect a system with CAN high-speed-interface (CAN-Buslayer ISO-11898 or CAN C) to lowspeed fault tolerant (CAN-Buslayer ISO-11519 or CAN B) busses. The IF-CAN-BC is plugged into a CAN highspeed interface and converts the signals of this interface for compatibility with fault tolerant low speed signal requirements A DC Voltage from 8 to 36 volts can be connected to pin number 9 of either the low speed or the high speed connector. An internal voltage regulator and decoupling diodes supplys the internal circuits with the proper voltage.
