   |                    MISCELLANEOUS NOTES                     |
   |------------------------------------------------------------|
   | The jumper settings for the entire line of E2100 card are  |
   | exactly the same. To save space we have only listed these  |
   | settings once instead of including a table for each card.  |
   | The only differences between the models are the wiring     |
   | types and topologies.                                      |
