A PPENDIX C. D EMONSTRATION B OARD
The demonstration board allows you to exercise the digital I/O on a RabbitFLEX board. The demonstra-
tion board, shown in Figure C.1 , has four connections for digital inputs that create logic highs while the
corresponding pushbutton switches on the demonstration board are pressed. There are four connections for
sinking digital outputs that light up corresponding LEDs while a digital output on the RabbitFLEX board
is activated.

C.1 Demonstration Board Connections
Before running digital I/O sample programs that can use the demonstration board, connect the demonstra-
tion board to the RabbitFLEX SBC40 with one of the cable assemblies included with the RabbitFLEX
SBC40 Tool Kit.
C.1.1 Power and Ground Connections
There are two power connections on the demo board: +5 V and K. If you selected the 5 V supply option on
the RabbitFLEX SBC40 connector you will be using, you can attach its corresponding green wire from the
cable assembly to +5 V on screw terminal header J1 on the demo board. Otherwise you will need to attach
an external +5 V power supply to J1.
Connect the black wire from the cable assembly to GND on screw terminal header J1. If you are using an
external power supply, connect its ground to GND on J1 as well.
