The driver only decodes the KM/Hr field and converts it internally to m/s.
That means that the unit the user has to define in the Database Setup program for the speed observation must be m/s!

No special two-way RS-232 cable connection is required.
The driver does not send any command to the Doppler, so the unit should already be in continuous data output mode.

Only a speed observation is required.

The unit for the Speed observation should be meters/second, the recommended a priori sd 0.1.

The speed driver has the possibility to validate the speed data that is being decoded.
To use this feature the user has to manually edit the "DRIVERS.IO" file. Locate the DrvEM200Speed.exe driver.
Any number that is present as command line argument will used as the maximum speed to be accepted by the driver.
