|                                    ----
|                                   |
------------------------------------

If the upper set of pins are jumpered,  the AUI is enabled, if the lower set is jumpered the thin net is enabled. And YES there IS a pin missing from the top row on the left.

The default for the switches is:

DOWN, UP, DOWN, DOWN, UP, UP, UP, UP

Don't change them!
