PREH Touch Commander


MonitorMice for Windows NT 4.0
Release 3.00c 03.02.1999

1. Release Notes

Because serial communications services are not available until late in the Windows NT 4.0 startup process, the touchscreen will not begin to function for several seconds after the Windows NT logon dialog is displayed.

The full-screen DOS mode is not completely supported by the Windows NT driver. The video mode in Windows NT and in the DOS application must be identical, in order for the mouse pointer to correctly follow your finger. If the video modes are not identical, the mouse pointer in the DOS application will act in the full-screen mode as though it had not been calibrated. The mouse can be used to control the full-screen DOS application.

The touchscreen control panel is optimized for resolutions higher than 640x480. When running 640x480 video modes you will not be able to view the entire touchscreen control panel. Hide the Windows NT toolbar, then drag the control panel window up by the title bar to access the bottom portion.

The Windows NT 4.0 beep service (BEEP.SYS) must be enabled in order for the touchscreen driver to correctly load. Use the Services object in the Windows NT 4.0 control panel to enable the beep service if it has become disabled.

MonitorMice for Windows NT supports from 1 to 32 serial touchscreen controllers connected to a single Windows NT 4.0 Workstation. It is possible to configure MonitorMice for Windows NT 4.0 for a wide variety of unique touchscreen applications that are not available during installation. This includes:

- single touchscreen configurations using COM ports higher than COM8 (COM1 - COM128 supported)

- multiple touchscreen configurations using a video signal splitter where more than one touchscreen responds to the same desktop area

- multiple touchscreen configurations where the desktop is shared across a number of displays other than 2, 4, 8, 16, or 32

Detailed information regarding these alternative touchscreen installations can be located on the Elo web site at www.elotouch.com.

The option to hide the mouse pointer in the touchscreen control panel doesn't work correctly after installation. You have to copy the file null.cur to the directory C:\Winnt\Cursors.
