SUMMARY: (full replies on request)
>From Curt Freeland:

    J1800 (Just behind the DB15 ethernet AUI connector) is the jumper you need.
    The Field Engineers manual says
    
    out forces AutoSense Ethernet (if > 30ma on the +12 return)
    out forces thin ethernet
    in forces thick ethernet.

>From Dan Lorenzini:

    The 4/110 is supposed to figure out which interface to use
    automagically. However, in our experience, this does not work
    flawlessly. There is a jumper that can be used to force using the
    thick interface, and I believe that it is J1800 located near the
    ethernet connector. (Jumper in=thick; out=auto select.)

Thanks,
Bill Selig
