My new Associate Controls Engineer was trying to configure a 9300-ENA module and changed an address, now i am unable to go on line thru my web browser. Is there something i can do to start over?

I believe setting dip switch 1 and 2 on, and cycling power will restore the factory defaults.

WireShark is a free Ethernet sniffer utility. When someone re-addresses a device and the re-addressing does not fully take or they did not document the new address (or addressed incorrectly), WireShark is a great tool for sniffing out what the new address may be. Make sure to turn off other ports on your development PC when sniffing, such as your Ethernet port. Try to limit all of the network traffic to just the device you are seeking out, such as disconnecting everything to that device other than your development PC.
