3.5 Sensor Configuration
A number of sensor parameters can be read and written over the CAN bus using the J1939
memory access (MA) protocol.
User level for access = 1
Key for access is equal to the
“seed” generated by the device.
All addresses are direct spatial (is pointer)
The access is similar to the SPN space. Each parameter has an individual size.
The tool shall issue a read or write command with a memory length of 1 (one).
In its
“proceed” reply, the device returns the actual number of bytes to be used for the trans-
fer.
LED parameters are volatile, they assume their default values after each reset.
3.5.1
Tool ISO name acceptance criteria
The sensor accepts MA sessions from any tool that fulfils all of the following criteria:
-
ISO name Function field = 129
-
ISO name Industry group field = 0
3.5.2
Adjustable Parameters
The following parameters are available for adjustment:

(4) LED default values depend on the current state; these settings are volatile
(5) Detection range can be adjusted to avoid issues with double echo detections.
