B.4 Using the Prototyping Board
The Prototyping Board is actually both a demonstration board and a prototyping board. As
a demonstration board, it can be used to demonstrate the functionality of the RCM2000
right out of the box without any modifications to either board. There are no jumpers or dip
switches to configure or misconfigure on the Prototyping Board so that the initial setup is
very straightforward.
The Prototyping Board comes with the basic components necessary to demonstrate the
operation of the RCM2000. Two LEDs (DS2 and DS3) are connected to PA0 and PA1, and
two switches (S2 and S3) are connected to PB2 and PB3 to demonstrate the interface to
the Rabbit 2000 microprocessor. Reset switch S1 is the hardware reset for the RCM2000.
To maximize the availability of RCM2000 resources, the demonstration hardware (LEDs
and switches) on the Prototyping Board may be disconnected. This is done by cutting the
traces below the silk-screen outline of header JP1 on the bottom side of the Prototyping
Board. Figure B-4 shows the four places where cuts should be made. An exacto knife
would work nicely to cut the traces. Alternatively, a small standard screwdriver may be
carefully and forcefully used to wipe through the PCB traces.

Demonstration Hardware on Prototyping Board
The power LED (PWR) and the RESET switch remain connected. Jumpers across the
appropriate pins on header JP1 can be used to reconnect specific demonstration hardware
later if needed.
