SAE J1708
J1587 and SAE J1922. The protocol is maintained by SAE International
.
Description
The standard defines a 2-wire 18
8N1
format.
The hardware utilized are RS-485 transceivers wired for open collector operation through the use of a pullup and pulldown of the separate data lines. Transmission is accomplished by controlling the driver enable pin of the transceiver. This method allows multiple devices to share the bus without the need for a single master node. Collisions are avoided by monitoring the bus while transmitting the MID to ensure that another node has not simultaneously transmitted a MID with a higher priority.
History
SAE J1708, although still widely used, is replaced by SAE
J1939 which is a CAN
protocol.
