Linking two CAN networks
The module CAN-CBM-Bridge/2 can link two independent CAN networks. The networks can be operated with different bit rates. The module operates with a MB90F543 microcontroller, which buffers the CAN data in a local SRAM. The firmware is in the flash. A serial EEPROM stores parameters.

CAN-Interface
The ISO 11898-compatible CAN interfaces allow each a maximum data-transfer rate of 1 Mbit/s. The CAN interfaces are electrically insulated by optocouplers and DC/DC converters. They are connected via 5-pin screw/plug connectors in Combicon design.

Programming
The RS-232 is used as serial programming interface. The interface is connected via a DSUB9 connector.
The CAN-CBM-Bridge/2 module can easily be configured by means of a terminal, e.g. Windows Hyperterminal.
The module is a 11-bit-ID and a 29-bit-ID Bridge. Up to 26 unidirectional links of identifiers can be configured. Beyond that up to four masks can be defined to link the identifiers completely or to link defined ranges of identifiers.
