1. INTRODUCTION
The BL2100 is a high-performance, C-programmable single-
board computer that offers built-in digital and analog I/O com-
bined with Ethernet connectivity in a compact form factor. A
Rabbit®2000 microprocessor operating at 22.1 MHz provides
fast data processing. An optional plastic enclosure and
LCD/keypad module are available, and may be wall-mounted.
1.1 BL2100 Description
The BL2100 is an advanced single-board computer that incorporates the powerful Rabbit
2000 microprocessor, flash memory, static RAM, digital I/O ports, A/D converter inputs,
D/A converter outputs, RS-232/RS-485 serial ports, and a 10Base-T Ethernet port.
1.2 BL2100 Features
•Rabbit®2000 microprocessor operating at 22.1 MHz.
•128K static RAM and 256K flash memory standard, may be increased to 512K SRAM
and 512K flash memory.
•40 digital I/O: 24 protected digital inputs and 16 high-current digital outputs provide
sinking and sourcing outputs.
•15 analog channels: eleven 12-bit A/D converter inputs, four 12-bit D/A converter 0–10 V
outputs (selected models).
•One RJ-45 Ethernet port compliant with IEEE 802.3 standard for 10Base-T Ethernet
protocol (selected models).
•Two Ethernet status LEDs (selected models).
•Four serial ports (2 RS-232 or 1 RS-232 with RTS/CTS, 1 RS-485, and 1 CMOS-com-
patible programming port).
•Battery-backed real-time clock.
•Watchdog supervisor.
•Optional backlit 122 × 32 graphic display/keypad module.
•Remote program downloading and debugging capability via RabbitLink.
•Boards with the CE mark on their RabbitCore module are CE-compliant.
2Smartcat (BL2100)
Four BL2100 models are available. Their standard features are summarized in Table 1.
Additional 512K flash/512K SRAM memory options are available for custom orders
involving nominal lead times. Contact your Rabbit sales representative or authorized
distributor for more information.
Appendix A provides detailed specifications.
1.2.1 Connector Options
In addition to the standard screw-terminal connectors supplied on BL2100 boards, IDC
headers, bottom-mount sockets, and polarized friction-lock terminals may be factory-
installed instead. Visit our Web site at www.rabbit.com or contact your Rabbit sales
