Programming the Bridge requires the knowledge of NMEA 2000. This may be extremely useful for program debugging or network diagnostics. #How to nmea 2000 network updater freeCAN format) which can be opened, viewed and converted with the free CAN Log Viewer tool. The Brige can also save all messages from both interfaces to a binary log files (. The program can dump all NMEA 2000 messages and program variables to a text file on a MicroSD card.

The Bridge contains a built-in compiler of a simple programming language. Drawing of connectors is available in Appendix C of the User Manual. For other networks, an adaptor cable may be required. The Bridge is equipped with two connectors (on CAN1 and CAN2 network interfaces) compatible with Raymarine SeaTalk NG or with two connectors compatible with NMEA 2000 Micro Male (used in Garmin networks). The programming language of the device is not designed for full-fledged applications, but one can create, for example, a gateway from a J1939 network to NMEA 2000. Create gateways for networks based on CAN protocol operating at a speed of 250 kbps.One of the CAN-interfaces on the device has high-voltage galvanic isolation and can operate at a higher supply voltage. ![]()
