Troubleshooting Information (Cont.)
Symptom
After downloading a panel file or
firmware to a G4 device, the
device behaves strangely.
NXP-TPI/4 NetLinx Touch Panel Interface
Solution
Symptoms include:
• Having to repeat the download.
• Inability to make further downloads to the panel. May get "directory"
errors, "graphics hierarchy" errors, etc.... indicating problems with
the Compact Flash.
• Panel will not boot, or gets stuck on "AMX" splash screen.
• Other problems also started after downloading to a new panel or a
panel with a TPD4 file that takes up a considerable amount of the
available Compact Flash.
Cause:
• If the G4 device already contains a large enough file, subsequent
downloads will take up more space than is available and could often
corrupt the Compact Flash. The demo file that typically ships with G4
panels is one such file.
Solution:
• DO NOT download TPD4 files (of large size) over the demo pages, or
any other large TPD4 file.
• First download a small blank one page file to the G4 panel using the
Normal Transfer option to send/download the page. Reboot the
device, then do your regular file or firmware download.
