SET PARAMETER is used for setting a given parameter to a given value.

The message can be used for the following purposes:

  • Stop continuous data reporting.

  • Set reference values.

  • Set offset to road and air temperature.

  • Configure the serial port speed.

  • Configure units of reported quantities.

Some of the parameters are read-only.

An attempt to set a value to a read-only parameter causes an INVALID DATA error.

Some of the parameters require a restart for the changes to take effect. The reported parameter value is reported immediately.
The response times can be longer when parameter values are changed. The extra time is needed to write parameters into the permanent memory before sending the response.
