4.2 – Common Faults
Below are some common faults. Accompanying each one is a list of the most common solutions. While the lists of
solutions are not exhaustive, they represent the majority of the likely failures.
No devices show up in Control Center
o Ensure the PC is running Windows 98SE or later (Windows 95 is not suitable)
o If running Vista, ensure a Vista compatible version of Control Center is running (1.4.0 onwards)
o Check the PC is connected to the same Ethernet infrastructure the CobraNet is running on
o Check a network card has been selected for Control Center to use and if the PC has multiple cards, check it’s
the correct one
o Ensure the network card being used by Control Center has its IP address configured correctly
o Check the switches used to interconnect devices are powered up
o Check the CobraNet nodes on the network are powered up and running
o Check firewall and Internet security settings to ensure CobraNet traffic can pass through unabated. These
may need to be disabled for Control Center to work
o If the network switches are using a VLAN configuration, check the VLAN configuration is correct
o Check the correct cabling has been used for each connection and they have been terminated properly
The DialogBox does not show up in Control Center
o Check the DialogBox has power supplied to it and is turned on. Check the power light on the front
o Check the Ethernet cable is correctly connected to an active network I/O port on the switch
o If using a switch, ensure the Ethernet cabling is a standard patch cable and not a crossover type
o If the PC is wired direct to the DialogBox, make sure a crossover cable is used
The DialogBox appears but its icon never turns green
o Check the DialogBox has a valid IP address
o Check IP address on the PC and the device to ensure they are within range of one another
