Enabling Video Pass-Through Control On A Touch Monitor - AMX TPI-PRO-DVI-2 Instruction Manual

Enabling Video Pass-Through Control on a Touch Monitor

To enable a touch response on a panel page being routed through a computer, you must establish pass-thru control. Pass-thru
control allows the TPI to act as a control bridge between a PC and a touch monitor. The touch monitor control option is available
only if a Video Fill has been applied to the panel page (in the TPDesign4 (Touch Panel Design software application).
With the panel page open in TPDesign4:
1. Select the States tab of the Properties Control Window.
2. Open the drop-down menu for the Video Fill property, and select the video slot (1-4) that will be used on the TPI.
The example shown in FIG. 28 indicates that only Input 1 is being used - in this case you would select Video Slot 1 (FIG. 29).

With Video Pass-Thru enabled, the panel's touch coordinates are passed as USB commands from the HD-15 connector on a TPI 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. 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.
PC control can be established by routing the Mouse and touch monitor input control through the TPI. In this scenario, the TPI is
virtually non-existent and is akin to connecting the touch monitor and mouse directly to the rear of the PC. The PC views the TPI
and the HD-15 and USB connectors as an adapter connected to a USB mouse device. This method allows for both mouse and touch
monitor input control of the PC (as seen in FIG. 28).
Follow these steps to configure the TPI to use a touch monitor for touch and mouse pass-thru control of a PC:
1. Discharge any acquired static electricity by touching a grounded metal object; disconnect the incoming power connector from
the rear of the TPI.
2. Connect a USB mouse to one of the Type-A USB ports on the front or rear of the TPI.
3. Connect a USB cable from a USB port on the PC to one of the Type-B USB ports on the rear of the TPI (labeled SOURCE
KEYBOARD/MOUSE).
4. Connect a DVI video output on the PC to the VGA/RGB/DVI Input connector on the rear of the TPI that corresponds to the
Type-B USB port to which the PC is connected. For example:
If the PC is connected to Type-B USB port #1, then the video output on the PC must be connected to INPUT 1.

If the PC is connected to Type-B USB port #2, then the video output on the PC must be connected to INPUT 2.

If the PC is connected to Type-B USB port #3, then the video output on the PC must be connected to INPUT 3

(inputs 3 & 4 available only on the TPI-PRO-DVI-4).
If the PC is connected to Type-B USB port #4, then the video output on the PC must be connected to INPUT 4

(inputs 3 & 4 available only on the TPI-PRO-DVI-4).
5. Connect the touch monitor's touch (keyboard/mouse) connector to the TPI:
Depending on the compatibilities of the touch monitor, they can connect to either the TOUCH INPUT (DB9) connector or one
of the Type-A USB ports (labeled KEYBOARD/MOUSE) on the TPI.
For touch monitors with Serial-touch connectors, use a DB9 Serial cable to connect the touch monitor's touch input

connector to the TOUCH INPUT (DB9) connector on the TPI. Refer to the TOUCH INPUT (DB-9) Port section on page 29 for
a description of the TOUCH INPUT connector pinouts.
For touch monitors with USB-touch connectors, use a USB cable to connect the touch monitor's touch input connector to

the KEYBOARD/MOUSE (USB Type A) connector on the TPI.
6. Connect the touch monitor's video output connector to the DVI OUTPUT 1 port on the TPI.
NOTE: This requires a CC-DVIM-VGAF DVI-to-VGA Adapter Cable (FG10-2170-13), not included.
7. Apply power to the TPI.
8. Code a button on the touch monitor page to enable the pass-thru feature on a selected input card slot.
