AMX MVP-8400i manual Plug-in the mini-USB cable into the corresponding port on the panel

Appendix C: Troubleshooting

6.Plug-in the mini-USB cable into the corresponding port on the panel.

7.Wait a few seconds and refresh the system. This re-establishes communication with the Virtual Master. The panel should now appear in the list of available devices.

Connection Status

Symptom: My Connection Status button isn’t blinking and it says the USB is connecting.

"USB Connecting" is displayed when the panel is trying to establish USB communication with the PC (either within the NetLinx Studio or TPDesign4 applications) but not establishing the connection.

1.Remove the USB connector from the panel and close any AMX applications.

2.Reboot the panel.

3.Launch the AMX application and attempt to reconnect to the panel.

4.If using Studio for Virtual Master communication, establish a Virtual Master connection, verify the correct System number, stop communication with the Virtual Master, and then re-establish communication by refreshing the system.

5.After the first page appears, re-connect the mini-USB connector to the panel and confirm the appearance of the USB icon in the System Tray.

Panel Doesn’t Respond To Touches

Verify that the protective laminate coating on the LCD is removed before beginning any calibration process.

The protective cover acts to press on the entire LCD and makes calibration difficult because the user can’t calibrate on specific crosshairs when the sheet is pressing on the whole LCD.

Batteries Will Not Hold Or Take A Charge

Symptom: Batteries will not hold or take a charge and there is no indication of charging, on the bargraphs or in the Batteries Setup page.

To keep the batteries from being damaged (from operating at too low a level), the firmware places them into a protected state.

The panel must have the latest firmware (if it doesn’t, the firmware can be found at amx.com, in the Dealers/Tech Center > Firmware Files.> Modero).

1.Load the firmware into the panel, using NetLinx Studio.

2.After loading the firmware, power cycle the MVP (this is a complete power cycle, not a Reboot). The panel will now show the current firmware version within the Setup > Panel Information page.

3.Connect the power supply to the panel. You will see 2 warning messages on the display.

The first one warns that the batteries are low and must be charged.

The second warning tells you that the second battery is in aprotected mode, and needs to be inserted into the first battery slot.

4.Swap the batteries, the top slot is considered the first slot, and now the batteries will be reset.

5.Wait a few minutes and then check the Batteries page on the MVP to see any charging activity on the bar graphs.

The "Sensor" device (in the Online Tree tab below the MVP panel)should show v1.24 or higher after the upgrade, as shown in FIG. 85:
