APPENDIX D. PROGRAMMING CABLE
Appendix E provides additional information for the Rabbit 2000
™
microprocessor when using the
DIAG and PROG connectors on the programming cable with the RabbitLink board. The PROG
connector is used only when the programming cable is attached to the PROG IN connector
(header J8) on the RabbitLink to download new firmware. Otherwise, the DIAG connector on the
programming cable is used to configure the RabbitLink’s network parameters, and also allows the
programming cable to be used as an RS-232 to CMOS level converter for serial communication.
