The Digital I/O accessory board may also be used to run the TOGGLESWITCH.C and the
SERIALTOSERIAL.C sample programs. This accessory board is included only with the
Deluxe Development Kit.
To install the Digital I/O accessory board, insert the strip of header pins included with the
accessory board into the socket at J12 on the bottom side of the Digital I/O accessory
board. Then line up the Digital I/O accessory board with the Interface Board standoffs/
connectors and install the Digital I/O accessory board pins into socket J2 on the Interface
Board. Secure the Digital I/O accessory board with the long plastic standoffs/connectors
from above as shown in Figure 6—note that one plastic standoff/connector needs to be
inserted “upside down” to secure the Digital I/O accessory board to the antenna bracket.
