Au GW3-1939-1708 is a family of gateway products which can convert SAE J1939 data to SAE J1708/J1587 data. It can be used for both stationary heavy duty diesel applications (such as Gen-set) and on-highway vehicles.
Pin out Definition
There are two DB9 connectors: a DB9 female connector on RS232 side, and a DB9 male connector on "BUS" side.
The RS232 connector can be used to connect to a Computer for device monitoring, license management and firmware updates. A RS232 serial extension cable (Au Part Number: CBL-RS232-01) can be used to connect the device to PC. For PC without Serial port, a USB to RS232 Converter cable (CBL-USB-232) can be used. The RS232 connector is not required to be connected during normal operation.
The BUS connector provides power supply, J1939 and J1708 connection to the device. The pin out is illustrated here:
