Just to answer my own question; I ended up buying this converter: [URL] and I found that it was actually pretty easy to make it work. Simply connect the 3424 to the serial port of the converter, connect the LAN end to the computer. Install the virtual COM software for the converter and then the software will automatically search for and find the 3424. I can then communicate with it through the COM port that the software has created. A pretty neat setup which was easier to make then I expected. 
Hi, I am wanting to configure the 3424 over a LAN connection by using this serial Ethernet converter. Does anybody have any experience or recommendations with using such a setup? I assume that I would have to install some kind of COM port drivers on my computer that the converter can use.
