Table A-1. RCM2200 Header Pin 1 Locations

Header	Description	Pin 1 (x,y) Coordinates (Inches)
J4	RabbitCore RCM2200 user board interface	(0.100, 1.445)
J5	RabbitCore RCM2200 user board interface	(0.100, 0.195)
J1	Programming header (top side)	(0.125, 1.515)

It is recommended that you allow for an "exclusion zone" of 0.25" (6 mm) around the RCM2200 in all directions when the RCM2200 is incorporated into an assembly that includes other components. This "exclusion zone" that you keep free of other components and boards will allow for sufficient air flow, and will help to minimize any electrical or EMI interference between adjacent boards. An "exclusion zone" of 0.12" (3 mm) is recommended below the RCM2200 when the RCM2200 is plugged into another assembly using the shortest connectors for headers J1 and J2 on the RCM2200. Figure A-2 shows this "exclusion zone."

A.2 Pinouts

The RCM2200 and RCM2300 modules have two 26-pin headers to which cables can be connected, or which can be plugged into matching sockets on a production device. The pinouts for these connectors are shown in Figure A-6 below.

A.3 Serial Communication

All DeviceMate serial communication for the purposes of the DeviceMate Development Kit is done via Serial Port D, and any programming is done via Serial Port B on the hardware platform to Serial Port A (the default Rabbit 2000 programming port) on the target device.

Figure A-7. DeviceMate Development Kit Default Serial Connections
(for Rabbit-based targets)

The default serial communication channels are set using the following macros in the TC_CONF.LIB library in the DEVGATE folder. The macro setting is shown for Serial Port D.
