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.
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 battery
charger will continue select the next highest address until it finds one that it can claim. See
J1939/81 for more details about address claiming.
