Appendix C: Troubleshooting
184 MVP-9000i 9" Modero® ViewPoint® Touch Panel with Intercom
MVP 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.
1.
Verify that the AP is configured to match the MVP panel Network Name (SSID) field, Encryption, Default Key, and
Current Key string.
2.
In NetLinx Studio, select Diagnostics > Network Address and verify the System number.
3.
If the IP Address field is still empty, give the device a few minutes to negotiate a DHCP Address and try again.
My AP Doesn’t Seem To Be Working
WEP will not work unless the same default key is set on both the panel and the Access Point (AP).
Example: If the access point was set to default WEP key 4 (which was 01:02:03:04:05), the Modero’s Default WEP key
4 must be set to 01:02:03:04:05.
NetLinx Studio Only Detects One Of My Connected Masters
Each Master is given a Device Address of 00000.
Only one Master can be assigned to a particular System number. If you want to work 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 can be assigned
System #1 and the NI-4000 can then be assigned System #2 using two open sessions of NetLinx Studio v 2.x.
Can’t Connect To a NetLinx Master
Symptom: I can’t seem to connect to a NetLinx Master using NetLinx Studio.
Select Settings > Master Comm Settings > Communication Settings > Settings (for TCP/IP) , and uncheck the
"Automatically Ping the Master Controller to ensure availability".
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, a connection may still be attempted, but a failure will take longer to be recognized.
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.
Only One Modero Panel In My System Shows Up
Symptom: I have more than one Modero panel connected to my System Master and only one shows up.
Multiple NetLinx Compatible devices, such as MVP panels, can be associated for use with a single Master. Each panel
comes with a defaulted Device Number value of 10001. When using multiple panels, different Device Number values
have to be assigned to each panel.
1.
Press and hold the Reset button (FIG. 48) to open the Setup page.
2.
Press the Protected button, enter 1988 into the on-screen Keypad’s password field, and press Done when finished.
3.
Enter a Device Number value for the panel into the Device Number Keypad. The default is 10001 and the range is
from 1 - 32000.
Panel Behaves Strangely After Downloading A Panel File Or Firmware
Symptom: After downloading a panel file or firmware to a G4 device, the panel behaves strangely.
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:
Remember that the Passphrase generator on the panel does not produce the same
Current Key if using the same passphrase on the AP.
If you are trying to connect to a Master controller that is behind a firewall, you may
have to uncheck this option. Most firewalls will not allow ping requests to pass
through for security reasons.
