CAN CBM Clock

CAN CBM Clock Overview:

The module CAN-CBM-Clock can link an external DCF77-clock signal receiver or an external GPS-receiver with the CAN bus. An additional internal real time clock (RTC) take over the transmission of the timestamp, if no external signal connected. The module operates with a MB90F543 microcontroller, which buffers the CAN data in a local SRAM.

The time information transmitted as timestamp to the CAN bus. The ISO 11898- compliant CAN interface allows a maximum data-transfer rate of 1 Mbit/s.The CAN interface electrically isolated by
optocouplers and DC/DC converters. It connects via a 5-pin screw/plug connector in Combicon style.

The module designed for hat-rail mounting. The connectors and status LEDs placed in the front panel. The linkage of the CAN bus to an external DCF77- or GPS-receiver is done via a serial interface. The physical layer of the serial interface is realized as an RS-232 interface.
