Activation and Deactivation of the M-Key-UpperClassFilter

In the VDP 08.3DB and VDP 40.3DI operator displays a touch screen is inte‐
grated allowing the operation via the touch-sensitive surface of the display.
The touch screen controller communicates with the control cabinet PC via the
CDI interface using the USB interface internally in the control cabinet PC.
No driver software is to be installed. For more detailed information, please refer
to the respective documentation of the Rexroth control cabinet PC.
From firmware version 02VRS and higher of the operating system on the control
cabinet PC, the M-Key-UpperClassFilter driver is installed and active ex works.
The M-Key-UpperClassFilter driver is used for maintaining the downward com‐
patibility of the M-Key-Code when existing software products are used on
devices of the V xx.3 generation. The incoming keyboard data stream is ana‐
lyzed and as soon as a M-key-code (F13-F24,...) is detected, the corresponding
Ctrl-LRShift-Alt-<n> code is inserted into the data stream. This is done in the
kernel level of the operating system.
NOTICE
If a USB special keyboard is used, it may be required to deactivate the M-Key-
UpperClassFilter, see chapter 9.2 "M-Key-UpperClassFilter" on page
To activate and to deactivate the filter, the both batch files mkeyfilter-ac-
tivate.cmd and mkeyfilter-deactivate.cmd are to be used. The sys‐
tem restarts after the execution of the batch files. The batch files are filed in the
directory Support ▶ MKey-Filter Driver.
