Problems with the LAN Interface
If LAN communication does not work
If you cannot verify the connection, or if the commands are not
accepted by the emulation module:
❏ Make sure that you wait for the power-on self test to complete before
connecting.
❏ Make sure that the LAN cable is connected. Watch the LAN LED's on the
back of the logic analysis system to see whether the system is seeing LAN
activity. Refer to your LAN documentation for testing connectivity.
❏ Check that the host computer or debugger was configured with the correct
LAN address. If the logic analysis system is on a different subnet than the
host computer, check that the gateway address is correct.
❏ Make sure that the logic analysis system's IP address is set up correctly.
If it takes a long time to connect to the network
❏ Check the subnet masks on the other LAN devices connected to your
network. All of the devices should be configured to use the same subnet
mask.
Subnet mask error messages do not indicate a major problem. You can
continue using the emulation module.
The subnet mask is set in the logic analysis system's System Admin
window. If it then detects other subnet masks, it will generate error
messages.
If there are many subnet masks in use on the local subnet, the logic
analysis system may take a very long time to connect to the network
