4.
Drive for a minimum of 30 seconds on dry road.
30 s
This changes road coefficient parameters
0x53
,
0x54
, and
0x55
(1 parameter for each laser).
•
When started, changes status bit reference setting ongoing to
1
= ongoing.
•
When finished, changes back to
0
= not ongoing. The action takes typically 30 seconds.
The command was successful if sensor if status bits 10 ... 13 (
reference setting
interrupted due to...
) all have value 0 (no error).
5.
Check that the sensor is not reporting errors.
Use the
SEND DATA
request, and check the unit status information from the
SEND DATA
response.

6.
To read road coefficients, give the following command and parameters:
GET PARAMETER 0x53 0x54 0x55
Write down the coefficients to use later on with another sensor.
If the adaptation was not successful, repeat the procedure.
Option B: using factory coefficients
Recommended to use factory default coefficient values if typical local dry road is not available and the
values cannot be copied from another sensor for which dry reference has already been done.
1.
Check that the sensor uses the following co-efficient values:
3.696
,
3.729
, and
3.664
Use the following message:
GET PARAMETER
If not, give the values for the 3 parameters (Road coefficient, laser 1, laser 2, and laser 3). Use the
following message:
