TCP/IP Development Kit
1. O
VERVIEW
The TCP/IP Development Kit provides a hardware platform
based on the Rabbit 2000
®
microprocessor, Dynamic C
®
, and
the tools necessary to develop a robust 10Base-T Ethernet appli-
cation.
1.1 Description
The TCP/IP Development Kit includes a TCP/IP Development Board (with a Rabbit
2000
®
microprocessor, flash memory, SRAM, Ethernet hardware, serial ports, digital I/O),
Dynamic C development software with TCP/IP stack and documentation on CD-ROM
(not a trial version!), a demonstration board, a power supply, and a serial programming
cable.
The TCP/IP Development Board included in the kit allows for immediate evaluation and
development of TCP/IP applications using the Rabbit 2000 microprocessor. Executable
code can be downloaded into flash memory or SRAM (an optional battery backup board
for SRAM and the real-time clock is available). Two communication ports are available—
an RS-232 port and a RS-485 port. Other features of the TCP/IP Development Board
include four high-current outputs, four digital inputs, seven timers, a real-time battery-
backable clock, and a 10Base-T Ethernet interface.
