MVP-8400i 8.4" Modero® ViewPoint® Touch Panel with Intercom
If there is a yellow exclamation point next to the AMX USB LAN LINK device (within the hardware devices section of
the Unplug or Eject Hardware window), stop and close the USB operation. Reconnect the USB cable to the panel and
repeat the setup procedures.
To remove the USB driver association from a previously connected touch panel, you must navigate back to the Device
Manager, right-click on the panel’s USB driver (example AMX USB LAN LINK #2) and select Uninstall from the
context menu and then OK.
Once the system completes the removal of the device, the Device Manager window will refresh, and the
device will no longer appear.
The next time this device is connected to the computer it will appear as a new hardware device and will need
to be associated again with the driver (refer to Configure the panel for USB communication section on
page 24).
Checking AMX USBLAN Device Connections via NetLinx Studio
Use the CC-USB Type-A to Mini-B 5-wire programming cable (FG10-5965) to provide communication between the
mini-USB Program port on the touch panel and the PC. This method of communication is used to transfer firmware KIT
files and TPD4 touch panel files.
1. Verify this direct USB connection (Type-A on the panel to mini-USB on the panel) is configured properly using the
steps outlined in the previous two sections.
2. With the panel already configured for USB communication and the Virtual Master setup within NetLinx Studio, its
now time to verify the panel is ready to receive files.
3. Click the OnLine Tree tab in the Workspace window to view the devices on the Virtual System.
The default System value is one.
4. Right-click on the System entry (A in FIG. 80) and select Refresh System. This causes a refresh of all project
systems, establishes a new connection to the Virtual Master, and populates the System list with devices on your
particular system.
A mini-USB connection is only detected after it is installed onto an active panel.
Connection to a previously powered panel which then reboots, allows the PC to
detect the panel and assign an appropriate USB driver.
