To maximize the availability of RCM2200 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. Cut the traces
between the rows as shown. An exacto knife would work nicely to cut the traces. Alterna-
tively, a small standard screwdriver may be carefully and forcefully used to wipe through
the PCB traces.Use jumpers across the positions on JP1 if you need to reconnect any of
the devices later on.
Figure B-4. Where to Cut Traces to Permanently Disable
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.
Note that the pinout at location JP1 on the bottom side of the Prototyping Board (shown in
Figure B-4) is a mirror image of the top-side pinout.
The Prototyping Board provides the user with RCM2200 connection points brought out con-
veniently to labeled points at headers J7 and J8 on the Prototyping Board. Small to medium
