The adapters I mentioned are fairly cheap and easy to configure.  The 
crimpers are fine for the RJ-45 end, but not the adapter end.  Just 
determine the correct configuration and wire the adapter accordingly. 
Then use a standard ethernet cable.  Incidentally, if you goof in wiring 
the adapter, a cheap pin extractor tool is necessary to fix it.
