TPI-PRO Total Presentation Interface - Pro Edition
10. Use the CRT’s video adjust buttons to align the incoming video signal to fit into the available screen
area. Initially positioning the TPI-PRO incoming video can reduce any later adjustments of the
video through the RGB Setup page (H-position, V-position, H-size, etc.)
Example 3 (Using a Touch Panel for Mouse / Touch Pass-Thru Control)
The example below displays a typical installation for using a touch panel for mouse and touch pass-thru
control.
To enable a touch response on a panel page being routed through a computer, you must establish
pass-thru enabling. Pass-thru control allows the TPI-PRO to act as a control bridge between a computer
and a touch panel.
The touch panel control option is available by either selecting a Video Fill (select Yes from the Windows
>> Properties >> States TPD4 drop-down menu to enable the option) or by enabling pass through via
the ^PPS command. With Video Pass-Thru enabled, the panel's touch coordinates are passed as USB
commands from the HD-15 connector on a TPI-PRO to the connected PC. This feature works only if the
HD-15 connector is connected directly to the PC via the HD-15 port on the rear of the TPI-PRO. The
touch coordinates are scaled to fit the resulting window. This allows you to "synch" the touch actions
from the panel to those on the connected computer.
Computer control can be established by routing the Mouse and touch panel input control through the
TPI-PRO. In this scenario, the TPI-PRO is virtually non-existent and is akin to connecting the touch
panel and mouse directly to the rear of the computer. The computer views the TPI-PRO and the HD-15
and USB connectors as an adapter connected to a USB mouse device. This method allows for both
mouse and touch panel input control of the computer (as seen in FIG. 10).
