MVP-7500/8400 Modero Viewpoint Wireless Touch Panels
If the panel 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.
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.
1. DO NOT download TPD4 files (of large size) over the demo pages, or any other large TPD4 file.
2. First download a small blank one page file to the G4 panel using the Normal Transfer option to send/download the
page.
3. Reboot the device.
4. Do your regular file or firmware download.
