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.
3.2.2.
ECU Address
The default value of this setpoint is 26 (0x1A), which is the address representing an
Alternator/Electrical
Charging System
by SAE in J1939 tables B3 to B7. Electronic Assistant 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 CAN-BC-LED will continue select the next
highest address until it find one that it can claim. See J1939/81 for more details about address claiming.
