MW810 Display Owner’s Manual 27

The KEY ILLUMINATION CONTROL parameter enables or disables illumination of emergency and
function keys.
The
LABEL ILLUMINATION CONTROL parameter enables or disables illumination of display
labels.
The
PWR LED INTENSITY specifies intensity of the Power LED when the display is in standby
mode.
Brightness Control
If necessary, the maximal brightness level of the display can be limited. The MAX BRIGHTNESS
codeplug parameter defines relative brightness level, which cannot be exceeded by this
display.
Touch Screen Calibration
Sometimes there is a need to calibrate the touch panel attached to the display monitor, i.e.
to adjust the pushed position of the panel and its display position of the monitor. Even if the
touch panel has same dimensions as the display monitor, there may be minor variations in
between corresponding data points because of resistance variance of each panel.
When you use touch panel module for the first time, or, when there is discrepancy between
the pushed and displayed positions, then calibration is required. This needs to be done only
once, and then, calibration data is stored. The CPU will automatically calculate the touched
position on display monitor.
CAUTION: Re-calibration may be required when you see a discrepancy between the
touched and displayed positions. This adjustment may be executed with the Display
Calibration Tool.
Backward Compatibility
If your display is connected to one of the old MW800 CPU models (F5206A, F5207A, and
F5217A), enable supporting of the 1-Wire interface between CPU and Display. Use the
1W
SUPPORT
parameter for that purpose.
