Configuration and Setup

VTM-D15/A 15" MultiMedia Touch Panel Systems

Calibrating the Monitor

Once the monitor is resized, calibrate it to use the touch drivers.

1. In terminal emulator mode, there are 3 commands used for calibration:

! Calibrate sets the monitor to begin the calibration test mode.

! Get Cal provides you with the current calibration values.

! Check Cal allows you to manually check the calibration on the monitor by using your

touch on the panel to display an on-screen cross-hair.

2. Calibrate the TPI/3 by entering:

3. Press the middle of the on-panel cross-hairs as they appear. After the last cross-hair has been

depressed and the coordinates points have been set, a dialog displays the panel coordinate

values.

4. Press the screen to exit from the calibration session and return to the panel display.

5. Verify and check the calibration of the TPI/3 by entering:

6. Then begin touching the panel at various locations to reveal an underlying cross-hair. The

touch points and cross-hairs should correspond in their locations.

7. Exit the AxcessX or HyperTerminal programs.

Setting Up AXlink Communication from Master to the TPI/3

When the TPI/3 is either located too far or inaccessible to a direct PC connection, communication is

done through the Axcess Central Controller (Master). Communication through the Axcess Master

is done via the use of Send Commands that are sent to the device using a specific Device ID

number.

There are two programs that can be used to establish the communication in an Axcess control

system: AXCESSX or HyperTerminal. Both programs use the same sets of commands when

talking either serially or through an Axcess Central Controller.

Setting Up AXlink procedures

1. Note that the refresh rates and resolution options for the panel are 1024 x 768 @ 60 Hz.

2. Follow the procedures for configuring the TPI/3 (in sequence), beginning with theSetting Up

AXlink Communication from Master to the TPI/3 section on page 28, and Setting up the VTM-

D15/A touch device through AXlink section on page 29 before attempting to use the

VTM-D15/A with the TPI/3.

calibrate

Sets up the panel to begin the calibration process. Touch the cross-hairs that appear on the panel to com-

plete the calibration process.

check cal

Verifies that the panel has been correctly calibrated. Touch panel at any location and it should correspond

to the appearance of a cross-hair.
