Registry Options

The driver has one extra setting, which can block decoding for a while if the Javad system drops in position calculation mode.

This settings can be found in the Windows registry, at key:

HKEY_CURRENT_USER\Software\QPS\QINSy\8.0\Drivers\DrvJavadGril\NAVPOS\Settings\Minimum Position Age [ms]

Default is 1000 ms = 1 second. So if the postitioning system drops in calculation mode, nothing is decoded for one second.
