Address Resistor Selection Guide
The sensor has an address offset resistor input pin, which enables users to connect multiple sensors
on a same CAN bus network. During power up, the sensor considers Source Address from input
resistor value connected to the offset input pin (4
th
pin) and starts operating with that address; the table
below shows the input resistor values and corresponding source addresses.
If this feature is not required, user should connect the pin to ground and should not be left this pin
floating.
If the address resistor value is greater than 10KΩ, then sensor operates using the saved address from
flash memory. If there is no address found in the flash, it uses the default source address 0x80.
Sensor also supports J1939 based source address claim methods and user can save their preferred
address into flash memory in the sensor anytime during normal operation.
Note:
Replacing the offset resistor value with a new input value during the sensor normal operation, will
not change the source addresses immediately. New source Address will only be effective after a power
cycle to the sensor.
