HDV19391587 Data Sheet v1.00 Page 1 Model HDV19391587 J1939 to J1587 Translator The B&B Electronics HDV15871939 allows J1939 data to be converted to J1587 data in an on-road heavy duty vehicle. System Overview 9-Pin DLC J1939 Vehicle Bus Vehicle J1939 to J1587 Controller 1 Translator J1587 J1939 32 Pigtail 32 Pigtail Vehicle Controller 2 . +12V/GND 32 Pigtail Vehicle Controller n Functional Firmware Diagram J1939/J1587 Translation Table J1939 PGNs J1939 Input buffer/filter J1587 Output buffer J1587 PIDs General Firmware Description The firmware should receive J1939 PGN data and compare this to the translation table. If an SPN is in the PGN that is also in the translation table, the latest value of that SPN is stored for transmission on the J1708/J1587 bus. The translation table will hold up to 20 PIDs. At the time given by the translation table, the data values should be sent as J1587 PIDs.

Firmware Updates Firmware updates are done through the J1939 port. Firmware updates can be completed with any RP1210 hardware Translation table is hard-coded in firmware. Changing the translation table means updating the whole firmware image. PC tools for updating firmware can be provided.
