Software Configuration Problems
NI CVS-1450 Device Does Not Appear in MAX or in Vision Builder AI
© National Instruments Corporation
This appendix provides instructions for troubleshooting the NI CVS-1450
device.
Possible causes and solutions:
•
Verify that there is power to the NI CVS-1450 device and that both the
NI 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 NI 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 NI CVS-1450 devices, even if these
devices are on the same subnet. You can test this by connecting the
development computer and the NI CVS-1450 device directly to a
network port or by using a crossover cable between the NI CVS-1450
device and the development computer. If the NI 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 NI CVS-1450 device. Consult your network
administrator.
•
The NI CVS-1450 device may have been configured on another
network and then moved to the current network. Reconfigure the
NI 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.
