From J1939-71
– Vehicle Application Layer
•
Software Identification
65242 ($00FEDA)
None of the application layer PGNs are supported as part of the default configurations, but they
can be selected as desired for either transmit or received function blocks.
Setpoints are accessed using standard Memory Access Protocol (MAP) with proprietary
addresses. The Electronic Assistant (EA) allows for quick and easy configuration of the unit over
the CAN network.
2.2. J1939 Name, Address and Software ID
The controller has a J1939 name which is broadcasted at power up and/or when its ECU Address
has been changed. The Software ID PGN gives useful information regarding the controller.
2.2.1. J1939 Name
The ECU has the following defaults for the J1939 Name. The user should refer to the SAE
J1939/81 standard for more information on these parameters and their ranges.

The ECU Instance is a configurable setpoint associated with the NAME. Changing this value will
allow multiple ECUs of this type to be distinguishable by other ECUs (including the Electronic
Assistant) when they are all connected on the same network.
2.2.2. ECU Address
The default value of this setpoint is 128 (0x80), which is the preferred starting address for self-
configurable ECUs as set by the SAE in J1939 tables B3 to B7. The EA will allow the selection of
any address between 0 to 253, and
it is the user's responsibility to select an address that
complies with the standard
. The user must also be aware that since the unit is arbitrary address
capable, if another ECU with a higher priority NAME contends for the selected address, the
controller will continue select the next highest address until it finds one that it can claim. See
J1939/81 for more details about address claiming.
