Control device for data transmission in data bus, has microprocessor detecting and evaluating data bus-voltage level, where high-speed-CAN and low-speed-CAN-transceivers are distinguishably and individually controllable over voltage level

摘要

The device (1) has a switch device (2) with a freely programmable microprocessor for detecting and evaluating a data bus-voltage level. A high-speed-CAN-transceiver (7) and a low-speed-CAN-transceiver (8) are distinguishably and individually controllable over the data bus-voltage level. The high-speed-CAN-transceiver has a high data transmission rate, and the low-speed-CAN-transceiver has a low data transmission rate. An independent claim is also included for a method for operating a control device.
