What is your home network? If you can run thinwire, flip the switch on the Etherport SE towards the BNC port and plug in.

If your home network works with 10mbps utp, you need an AUI transceiver which plugs into the 15 pin connector -- with a bayonet fastening. Most transceivers will work.

Some, perhaps many, utp network routers don't work with old utp network transceivers. One trick is to interpose a bridge between the router and old ethernet card:

Old NIC <--> AUI transceiver/utp <--> utp bridge <--> utp router.

The utp bridge is just an old 10mbps unintelligent network bridge.
