3.5 Internal configuration
It should not be necessary to open the Development Unit unless changing the internal switches
for DR operation or accessing the internal test pins. Most combinations of I/O can be made from
the front panel configuration switch. In the event that it is necessary to open the unit, Figure 3-5
illustrates the internal layout of the Development Unit board.
Figure 3-5 Internal layout of the Development Unit
As shown in Figure 3-5, there is a selection of links that can be configured to provide
functionality depending on the application. Table 3-4 lists the functions available.
