You might have to reinstall the NIC adapter and the
software drivers that came with it.
d If you are getting a normal ping response, next ping
your PC IP address. You should see four lines that read
something like this “Reply from 192.176.xxx.xxx: bytes=32
time<10ms TTL=64”. A successful ping means TCP/IP is
installed and correctly initialized. If you are getting
anything else, there is a problem with your TCP/IP
protocol. Remove the TCP/IP protocol that you have in
your network configurations and then reinstall it.
If the ping failed with “Request timed out” errors
1 Check the cabling. (Did the cable become unplugged?)
2 Test the cabling connection by disconnecting and
reconnecting the cabling and check the PC for the
network connection status.
3 Check the hub, switch, or router settings. Make sure the
instrument is not connected to the switch or hub cascade
port. Try a different switch or hub.
4 Power off the hub/switch or router and power it back on
again, then repeat the instrument's ping test. Use a
crossover cable (no switch/hub) to one instrument and
ping again.
If ping succeeds, but you still cannot connect
1 Consider if the network is just very busy. If there is too
much traffic on the network, this can interfere with data
acquisition and instrument control. Monitor the collision
lights on the switch or hub.
2 Verify that the same IP address is used in the instrument
and the data system.
