NXP-TPI/4 NetLinx Touch Panel Interface
Step 3: Calibrating the TPI/4
1. Firmly press the front panel CALIBRATE button on the TPI/4. This process opens a calibration
page that uses a series of crosshair coordinate intersections to calibrate the touch panel (using the
newly selected touch driver).
2. If the calibration fails, return to the Protected Setup page and select another touch input driver.
3. Press the crosshairs (on the Calibration page) to set the calibration points on the LCD. A mouse
press can be used to simulate a touch on a panel.
4. After the "Calibration Successful." message appears, press anywhere to return to the Setup page.
5. Press the Protected Setup button (located on the lower-left of the panel page) to open the Protected
Setup page.
6. Enter 1988 into the Keypad’s password field and press Done when finished.
7. Press the on-screen Reboot button to cycle power to the TPI/4 and incorporate the new settings. The
touch monitor goes blank for a few seconds during the reboot process. You can also use a mouse to
press the on-screen Reboot button.
8. Upon start-up, press anywhere on the screen to return to the Protected Setup page and begin
defining the communication properties.
Step 4: Accessing the Firmware Setup Pages
1. Press the front panel SETUP button to open the Setup page.
2. Follow the procedures in the Configuring Communication section on page 33 to configure the
communication parameters for the NXP-TPI/4.
If the wrong touch driver is selected prior to the calibration process, press any
front-panel button to exit the calibration process and re-select another touch driver.
If using a CRT monitor, DO NOT PRESS THE CALIBRATE BUTTON. Refer to the
Step 1: Setting the Output Resolution on the TPI/4 section on page 28 for detailed
CRT screen adjustment procedures.
It is recommended that you calibrate the TPI/4 before its initial use, after completing a
firmware download, and after switching touch input drivers (and touch devices).
