Display Units • Display Units 5D5600.0x and 5D5601.0x
19.6 Integrated Keys
Configuration of all keys and evaluation of key strokes is made using Mkey utilities and Mkey
driver (see the Provit Mkey Utilities User Manual).
• Function Keys
The 26 function keys can be programmed by the user. Likewise, the integrated
LEDs are available in every key . On the function keys the letters (A to Z) are
printed. The area underneath can be labeled using legend strips (see the "Key
Labels" section).
• Softkey Buttons
The 20 Softkey buttons are arranged below the display and likewise can be
programmed by the user. This also applies for integrated LEDs in each key.
Softkey buttons can be labeled using legend strips without constraint (see
section "Key Labels").
• System Keys
Functions for the 26 system keys (numerical Block, Ctrl, Alt, Del, Tab, Windows)
are the same as with conventional PCs. An exception however is the [Layer]
key, which allows multiple assignment for all existing keys (similar to the shift
key). The display units 5D5600.0x and 5D5601.0x allow up to 4 levels to be
used (multiple assignments). In this case, keys are defined as a level selector
switch (see the Provit Mkey Utilities User Manual). The system keys are printed
at B&R and are unable to be labeled.
It is important to note that a maximum of 2 special keys can be pressed
simultaneously, otherwise the key code can no longer be recognized correctly
(with the exception of [Ctrl]+[Alt]+[Del]).
19.7 Reset Button
A reset button is accessible through a small gap behind the front cover of the display unit.
Triggering of a reset after pressing the button is delayed by approximately 2 to 3
seconds. Do not attempt to initiate a reset by repeated or forced pressing!
