Troubleshooting
This appendix provides instructions for troubleshooting the NI CVS-1450
device.
Software Configuration Problems
CVS-1450 Device Does Not Appear in MAX or in Vision Builder AI
Possible causes and solutions:
• Verify that there is power to the CVS-1450 device and that both the
CVS-1450 device and the development computer are properly
connected to the network. The POWER OK LED should be lit. When
you click Browse, the ACT/LINK LED on the CVS-1450 device
should flash to indicate that communications are taking place.
• Certain network devices, such as switches and routers, may filter out
the directed UDP broadcast packets the development computer uses to
communicate with unconfigured CVS-1450 devices, even if these
devices are on the same subnet. You can test this by connecting the
development computer and the CVS-1450 device directly to a network
port or by using a crossover cable between the CVS-1450 device and
the development computer. If the CVS-1450 device appears in the
software using this configuration, but not when connected to the larger
network, the network is not properly communicating with the
CVS-1450 device. Consult your network administrator.
• The CVS-1450 device may have been configured on another network
and then moved to the current network. Reconfigure the CVS-1450
device on the current network.
• The grade of cable you are using may be insufficient for the speed of
your network, or you may be using the wrong type of Ethernet cable.
Use a straight-through cable when connecting to network hardware.
Use a crossover cable to connect directly to the development computer.
