NOTE
If screen resolution changes are made via the Windows NT Control Panel, the console application’s active screen
initialization file may require changes via the UDS Configurator program. This is especially true if the active screen
initialization file was set-up for a resolution higher than the new resolution. For example, assume the active screen
initialization file was set-up for a resolution of 800 x 600 pixels, the resolution setting is changed from 800 x 600
pixels to 640 x 480 pixels, and the console application is restarted without any active screen initialization file edits.
In this example, the right-most area (20% of horizontal resolution) and the bottom-most area (20% of vertical
resolution) of the console’s screen will be truncated from the screen, even when the console application is run “full
screen” enabled (GUI not resizable or movable). See the UDS Configurator User’s Manual (AE/LZB 119 1896) for
additional details.

6.1.8 Touch-Screen Monitors
As described in section 2.1.2.2 of this manual (page 9), the C3 Maestro console for Windows NT can be equipped with a
touch-screen monitor. Touch-screen software installation and configuration is always accomplished after the installation of
Windows NT. The following touch-screen configuration settings are recommended for the C3 Maestro console for
Windows NT:
•
mouse button emulation mode = drag enabled and double-click disabled (Elo TouchSystem “Mode 5”); if this
emulation mode is not used, instant transmits and some other timed touch events may not operate properly
•
generate click sound on touch = enabled
•
parallax error calibration = per installation’s monitor-to-eye level/position relationship (re-calibration recommended
if this relative level/position changes)
•
other settings = per installed driver defaults or as necessary
The console application has no knowledge of the touch-screen—it cannot detect the presence or absence of one.
Windows NT and the touch-screen driver handle all touch-screen actions by converting touch-screen inputs to equivalent
mouse move-and-click actions. Windows NT then passes these actions on to the console application for interpretation.
When a touch-screen driver is installed, the installation software normally automatically creates a new icon in
Windows NT Control Panel. Configurations should be made via this icon’s respective dialog box. The Elo TouchSystems’
icon and dialog box are show in Figure 6-3.
Normally, if a touch-screen monitor is purchased from the factory with the console equipment package, the touch-
screen’s controller board is factory-installed within the PC and the driver software is factory-installed and configured as
described above (less parallax error calibrations). Driver software is supplied on disk by the touch-screen’s manufacturer.
Parallax error calibrations or re-calibrations may be performed at any time. The procedure presents a series of screens
which ask the user (for example: dispatcher) to touch several different reference areas on the monitor’s screen. Ideally, initial
calibration is accomplished when the console’s monitor is in its final position at the dispatch center, the dispatcher’s eye
level/position is known, and this relative level/position is used as a reference. Re-calibration is recommended whenever a
