Troubleshooting
This appendix provides instructions for troubleshooting the NI 1450.
Software Configuration Problems
NI 1450 Does Not Appear in MAX or in Vision Builder AI
Possible causes and solutions:
• Verify that there is power to the NI 1450 and that both the NI 1450 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 1450 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 1450s, even if these devices are on
the same subnet. You can test this by connecting the development
computer and the NI 1450 directly to a network port or by using a
crossover cable between the NI 1450 and the development computer.
If the NI 1450 appears in the software using this configuration, but not
when connected to the larger network, the network is not properly
communicating with the NI 1450. Consult your network administrator.
• The NI 1450 may have been configured on another network and then
moved to the current network. Reconfigure the NI 1450 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.
