1.3.4.1 jPOD™ Vehicle Bus Adaptor
The CalAmp jPOD Adapter is a J1939 compliant device that reads the parameters broadcast
in the J1939 bus, processes them and provides filtered vehicle data to the LMU-4200™.
A script is written using a special software tool and loaded into the jPOD. This script defines
the specific parameters (PGNs/SPNs) to read, how to process them and how to send them
to the host. The script does not send any requests onto the bus.
