TPI/4 and Panel Interface Setup

NXP-TPI/4 NetLinx Touch Panel Interface

5. After the startup routine, the connected touch panel displays one of two possible screens:

 If the resolution of the TPI/4 matches the supported resolution of the panel, continue by

setting the touch drivers associated with the LCD (if any). Refer to the Step 2: Setting the

Touch Drivers section on page 29.

 If the TPI/4 output resolution does not match the resolution of the connected panel, an OUT

OF RANGE message appears, and you must use the following steps to adjust the output

resolution of the TPI/4 to match the panel.

This feature is monitor dependant and the range message is generated by the monitor (not by

the TPI/4). LCD monitors do not display a message but appear blank.

Step 1: Setting the Output Resolution on the TPI/4

To correct the problem of an OUT OF RANGE message, the TPI/4 output resolution must be set to

match the same output pixel resolution and refresh rate set on the connected panel/monitor.

The default TPI/4 output resolution is 640 x 480 @60Hz. Use the front panel RESOLUTION button to

alter the outgoing resolution (for a maximum of 1280 x 1024 @60 Hz).

1. Press and firmly hold-down the front panel RESOLUTION button. This single press opens the

Resolution Setup page (FIG. 18).

2. Firmly press the RESOLUTION button again to cycle through the available resolution settings.

Every consecutive button push cycles the output resolution to the next highest available setting. A

double-push of the RESOLUTION button adjusts the resolution to previous setting. The

following list describes the available pixel display and refresh rates.

FIG. 18 Resolution Setup page (showing comparative resolutions)

Previously saved output resolution

Currently selected output resolution

Setting the resolution begins by displaying a comparison of the current/original output

resolution of the TPI/4 (on one line) and then displaying the first selectable display

resolution and refresh rate (on the next line). The selection process originates at a

640x480@60Hz display option and with every consecutive single push of the

RESOLUTION button, the TPI/4 resolution increases to a maximum output of

1280x1024@60Hz.

• 640 x 480 @60Hz (default) • 800 x 600 @72Hz • 1024 x 768 @75Hz

• 640 x 480 @72Hz • 800 x 600 @75Hz • 1280 x 1024 @60Hz (highest setting)

• 640 x 480 @75Hz • 1024 x 768 @60Hz

• 800 x 600 @60Hz • 1024 x 768 @70Hz
