Switch Settings
In addition, the Switch Settings area of the additional EFDMIM
Configuration View provides a table containing a series of read-only indicator
buttons that (if they appear depressed) indicate which jumper settings are
enabled on the EFDMIM board. Table 6-15 provides a list of the jumper
setting information fields.
The Control button accesses the EFDMIM Control View, providing the Model
