The jCOM.J1939.GPS device connects to an SAE J1939 network and reports the vehicle position (PGN 65267 – Latitude & Longitude) with a one-second frequency, according to the SAE J1939-71 Standard.
The integrated J1939 protocol stack automatically negotiates a node address in the range of 128 to 247. The GPS data is broadcast by using the global destination address (255 = 0xFF). The device’s firmware can be updated on-site per the integrated RS232 port, which also allows the loading of customer-specific features.
The content of delivery includes the jCOM.J1939.GPS module and the GPS antenna (preferred installation location is the driver cabin, i.e. close to the wind shield).
