CPU to Option Card Connectors
The PK1 and PK2 connectors located at the top side of the ADS CPU card are used to connect the board
to option cards. The option cards are designed to add new capabilities to the ADS. A number of option
cards, such as the PCMCIA Adaptor Card, are available. You may want to develop your own add-on cards.
Figure 3-3 shows pin assignments for the PK1 connector and Table 3-3 provides signal descriptions for the
connector. Figure 3-4 shows pin assignments for the PK2 connector and Table 3-4 provides signal
descriptions for the connector.
