The Vr Touchscreen
The Vr Touchscreen is designed to be used with VrOne and VrTwo and offers 567 user definable buttons on a dynamic LCD touch surface in a 7-inch form factor. Each button has the ability to output a Vr button number, Vr macro name and (or) start a Vr Function key. Any valid Vr key-in string may be placed on a Vr Touchscreen button. Programming the screen is as easy as touching the program button then the button to program. Each button may have its own text, color, text font and text. The 567 buttons are on 9 overlays of 63 buttons each.
The top row of the touch screen is the overlay row and is used to select one of nine menu overlays.
The Vr Touchscreen programmable push button interface
The Vr Touchscreen is an additional Windows Screen and requires a VGA input from the computer for the display and a USB connection for the touch interface.
If your graphics card has two VGA outputs, one may be used to drive the touchscreen. NOTE: Many of the stereo cards for VrTwo such as the PNY NVIDIA Quadro4 980 XGL and the PNY NVIDIA 1300 FX have two outputs but stereo requires the overlay plane for interactive graphics and connecting a second screen uses the overlay plane.
A second video card may need to be installed to support the touchscreen. These second cards are inexpensive and can be inserted into an open PCI slot in the computer. Be careful to purchase a PCI graphics card and not a PCI Express (PCI-X) card as there are multiple PCI slots in a computer and one or none PCI Express slots.
Following is show a PCI ATI Radeon 7000 graphics card which can be purchased from www.zipzoomfly.com for about $45.00.
Connect the touchscreen to a VGA interface and plug the USB connector in.

The Vr Touchscreen can be configured for a resolution of 800 by 600 pixels or 1024 x 768. The newer touchpads do not support the 800 by 600 resolution and should use 1024 by 768.

The Touchscreen Parameter File – The parameter file name that contains the Vr Touchscreen button assignments and parameters is defined in the Vr Configuration program from the Configuration -> General pull-down. By default this file name is assigned \vr\hostdir\default.ts. If you program any buttons on the Vr Touchscreen you should not use this name as it will be overwritten on the next Vr software install.

VrOne 12-key button presses may be entered as b0-b11 where b0 is the snap on/off key and b10 is the * key and b11 is the # key.
Apply to all menus?
If this is checked then the button will be placed on all nine menu overlays.
