7 V - 16 V. A pre-fabricated cable for power supply is included in the scope of delivery. The connection allocation is shown in Table 2-1. The CANbridge is protected against polarity reversal, under-voltage and over- voltage. In the event of polarity reversal or under-voltage, it is switched off, with over-voltage an internal fuse is triggered. -

Page 14: Displays
Displays Displays The CANbridge has four 2-color LEDs (see Fig. 2-1 or Fig. 3-1). The LEDs behave in the following way depending on the operating mode of the CANbridge. Normal mode (Gateway mode) 4.1.1 PWR - LED The Power-LED (PWR) is lit when the CANbridge is connected to the supply volt- age and the microcontroller is installed. -
Page 15: Functional Description
CANbridge offers automatic baud rate detection. For configuration of the CANbridge, an ASCII-file is created and the configuration data are loaded onto the CANbridge via the serial interface with the aid of a download tool. The setting possibilities are described in Table 5-1. -
