Video Alignment Problems
If the touchscreen is responding and the data is linear, but a touch does not
activate the appropriate zone in the application, try realigning the video. Use
ELOCALIB under DOS or the Touchscreen Control Panel with all versions of
MonitorMouse. Improper video alignment may be indicated when the cursor
does not move at the same pace as a sliding finger, or when it moves in the
opposite direction. The cursor should always move in the same axis as your
finger.
If you have a DOS application, erase any ELOGRAPH.CAL files and repeat
video alignment process in the video mode used by your application. For
example, you may have a VGA monitor with your application running in text
mode, so perform video alignment in text mode rather than graphics mode.
Hardware Troubleshooting
Troubleshooting the touchscreen system hardware may require analysis of the
touchscreen, controller, cables, power supply, and the integration process. The
best place to start is with the controller.
Use the controller power-on diagnostics which are displayed when the Elo
driver software is loaded to check for specific faults (see “Diagnostic Codes” on
page A-78). If accessible, the controller’s diagnostic LED’s may identify a
problem (see “Diagnostic LEDs” on page A-76).
Also, check whether the controller is transmitting any touch data. Use the
COMDUMP program for serial controllers (see page A-69), or the BUSSTAT
program for PC-Bus controllers (see page A-74). You may encounter one of the
following symptoms:
• Constant touch data. If touch data is reported continuously, the most likely
problem is constant physical touch on the active area of the touchscreen,
usually from contact with the display bezel. When using ELODEV 1.5 or
later, a warning at installation will appear with some controllers. This
condition can be verified with BUSSTAT for bus controllers, and
COMDUMP for serial controllers. (See “Software Troubleshooting” on
page A-62.)
If an external serial controller is being used, disconnect the touchscreen cable
from the controller (the input to the controller, not the output to the COM
port) while COMDUMP is scrolling data.
