Using The Prototyping Board - Rabbit RabbitCore RCM3400 User Manual

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 RCM3400
right out of the box without any modifications to either board.
The Prototyping Board comes with the basic components necessary to demonstrate the
operation of the RCM3400. Two LEDs (DS1 and DS2) are connected to PD6 and PD7,
and two switches (S2 and S3) are connected to PD4 and PD5 to demonstrate the interface
to the Rabbit 3000 microprocessor. Reset switch S1 is the hardware reset for the RCM3400.
The Prototyping Board provides the user with RCM3400 connection points brought out con-
veniently to labeled points at header J1 and J3 on the Prototyping Board. Although header J1
is unstuffed, a 2 × 30 header is included in the bag of parts. RS-485 signals are available on
header J4, and RS-232 signals are available on header J5 (Serial Ports C and D) and header
J6 (Serial Ports E and F). A header strip at J5 allows you to connect a ribbon cable, and a 2 × 5
header is included in the bag of parts for optional installation at J6. The pinouts for these
locations are shown in Figure B-4.
