SAE J1708 is a standard used for serial communications between ECUs on a heavy-duty. The hardware utilized is RS-485 transceivers wired for open collector operation through the use of a pullup and pulldown of the separate data lines.
With {{{model|FMX640}}}, J1708 functionality is used to read vehicle's Fuel Level and Fuel consumption.
Because J1708 is not a CAN-BUS protocol, {{{model|FMX640}}} CAN1 and CAN2 lines cannot be used to read J1708 information. {{{model|FMX640}}} has a special J1708 Port, which utilizes an RJ9 4P4C connector.

==Software Configuration of {{{model|FMX640}}}with J1708==
{{{FMB640CFG|Firmware version: 00.00.11 or above
Configurator version: 0.13.35.29297 or above
}}}
J1708 configuration is done in the FMS IO Tab.

When J1708 is enabled as Fuel Level source, Fuel related data will be taken from the J1708 line, FMS Fuel data will be ignored.
==Connection with Vehicle port==
J1708 connector is not supported by all vehicles. Only VOLVO, RENAULT, and American truck manufacturers implement the J1708 connector.
