Serial Interface

The CAN-CBM-COM1 offers the linking of the CAN net to a serial interface. In the standard version the physical layer is realized as an RS-232 interface. Instead of the driver for RS-232 interface, the module can be equipped with piggybacks for RS-422, RS-485 or TTY-passive interfaces.

Local Microcontroller

A C505 microcontroller is used to handle the serial interface and the CAN.

CAN Interface

The ISO 11898-compliant CAN interface allows a maximum data-transfer rate of 1 Mbit/s (max. 35 m cable length). The CAN interface is electrically isolated by optocouplers and DC/DC converters.

Complete Firmware On-board

The complete EPROM resident CAN communication firmware for operation of the CAN-CBM-COM1 is contained in the scope of delivery. The module is available with CANlayer-2 protocol and CANopen.
