NXV-300 Modero Virtual Touch Panel
Appendix B - Troubleshooting
This section describes the solutions to possible hardware/firmware issues that could arise during the
common operation of a Modero touch panel.
Troubleshooting Information
Symptom Solution
When using G4 WebControl to
communicate with a target panel, a
VNC Server dialog appears on my
screen.
• During a WebControl connection to a target panel, a G4
Authentication dialog will ask you to enter the assigned password for
the panel before allowing access.
• If prompted with a VNC Server dialog, 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 panel appears
within the IP Settings section of this page
• Enter the IP Address and click OK. When prompted with the G4
Authentication popup, enter the panel’s WebControl password.
My Modero panel isn’t appearing
in my Workspace window.
• Verify that the System number is the same on both the NetLinx
Workspace window and the System Connection page on the Modero
panel.
• Verify that you have entered the proper NetLinx Master IP and
connection methods into the Master Connection section of the
System Connection page.
My Modero panel can’t obtain a
DHCP Address
In requesting a DHCP Address, the DHCP Server can take up to a few
minutes to provide the address.
• Verify that an active Ethernet connection is attached to the rear of the
Modero before beginning these procedures.
•Select Diagnostics > Network Address from the Main menu and
verify the System number.
• If the IP Address field is still empty, give the Modero a few minutes to
negotiate a DHCP Address and try again.
NetLinx Studio only detects one of
my connected Masters.
Each Master is give a Device Address of 00000.
• Only one Master can be assigned to a particular System number.
When working with multiple Masters, open different instances of
NetLinx Studio and assign each Master its own System value.
• Example: a site has an NXC-ME260/64 and an NI-4000. In order to
work with both units. The ME260/64 can be assigned System #1 and
the NI-4000 can then be assigned System #2 using two open
sessions of NetLinx Studio 2.
I can’t seem to connect to a
NetLinx Master using NetLinx 
Studio 2.
• From the Settings > Master Comm Settings > Communication
Settings > Settings (for TCP/IP), uncheck the "Automatically Ping
the Master Controller to ensure availability" 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: When trying to connect to a master controller that is behind a
firewall, unchecking this option may be required. Most firewalls will not
allow ping requests to pass through for security reasons.
