Appendix C: Troubleshooting
Overview
This section provides solutions to possible hardware/firmware issues that could arise during common operation of the TPI.
Troubleshooting Information
Symptom Solution
A DVI source is connected, but no
signal is detected, even though "DVI" is
selected as the Input Type in the Video
setup pages.
When using a DVI source, set the Input Type to DVI before attaching the DVI cable to the TPI.
If a DVI source is attached before setting the input to DVI, you may need to reboot the source for
it to recognize the DVI input description information required by the DVI standard.
See the Setup - Video Settings Page section on page 59 for details.
Manifest.xma can not be found. An
error occurs when sending a file to a
G4 panel.
Manifest.xma is the file that contains the listing for all the files. If you see this error again, before
attempting to send the file, uncheck the Smart Transfer box. It may be necessary do a Full Clean.
The video pages appear blank upon TPI
restart.
Wrong input type may be selected. Go to Video Settings page and select the appropriate input
type for that input.
When using G4 WebControl to
communicate with a target TPI, a VNC
Server dialog appears on my screen.
• During a WebControl connection to a target TPI you are prompted with a G4 Authentication
dialog which asks you to enter the assigned password for the TPI (before gaining access).
• If you are ever prompted with a VNC Server dialog, you must enter the IP Address of the target
panel. This can be found within the Setup > Protected Setup > System Connection page. -
This IP Address of the TPI appears within the IP Settings section of this page.
• Enter the IP Address and click OK. You will then be prompted with the G4 Authentication
popup where you must enter the TPI-PRO-DVI’s WebControl password.
The image on my video page isn’t
centered and/or aligned properly even
though I’m using the RGB/Video Setup
page alignment tools.
• Before an image can be displayed onto a touch panel or other monitor it must first be
positioned to occupy the available visible space on the panel/monitor.
• After completing those tasks, use the monitor’s video controls to stretch and move the
incoming video so that the borders of the desired resolution pattern follow the edges of the
screen without disappearing. There are normally 60 seconds before the resolution times-out,
but you can press the front panel RESOLUTION button again several time to return to the
previous resolution pattern and continue setting-up the monitor.
• Once these baseline alignments are done, use the RGB controls to complete the final
positioning of the incoming image/video.
I can’t seem to connect to a NetLinx
Master using my NetLinx Studio 2.8.
•From the Settings > Master Comm Settings > Communication Settings > Settings (for TCP/
IP), uncheck the "Automatically Ping the Master Controller to ensure availability" check box.
• The pinging is to determine if the Master is available, and to reply with a connection failure
instantly if it is not. Without using the ping feature, you will still attempt to make a connection,
but a failure will take longer to be recognized. Some firewalls and networks do not allow
pinging, though, and the ping will then always result in a failure.
• When connecting to a NetLinx Master controller via TCP/IP, the program will first try to ping
the controller before attempting a connection. Pinging a device is relatively fast and will
determine if the device is off-line, or if the TCP/IP address that was entered was incorrect. If
you decide NOT to ping for availability and the controller is off-line, or you have an incorrect
TCP/IP address, the program will try for 30-45 seconds to establish a connection.
Note: If you are trying to connect to a Master controller that is behind a f irewall, you may have to
uncheck this option. Most firewalls will not allow ping requests to pass through for security
reasons.
After downloading a panel file or
firmware to a G4 device, the device
behaves strangely.
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 internal disk.
• 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 disk space.
Cause:
• If the G4 device already contains a large enough file, subsequent downloads will take up more
space than is available and can corrupt the disk. 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.
