1. Introduction

The BL2100 is a high-performance, C-programmable single-board computer that offers built-in digital and analog I/O combined with Ethernet connectivity in a compact form factor. A Rabbit 2000^TM 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^TM 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-compatible 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.

Four BL2100 models are available. Their standard features are summarized in Table 1.

1.3 Optional Add-Ons

• Plastic enclosure (can be wall-mounted or panel-mounted) with LCD/keypad module that comprises a 122 × 32 LCD graphic display, 7-key keypad, and seven LEDs. The plastic enclosure consists of a base and a cover for an assembly made up of the BL2100 with the LCD/keypad module plugged in.
• Plastic enclosure base.
• LCD/keypad module.

One enclosure base is included with the Tool Kit.

Further details on these add-ons are provided in Appendix C and in Appendix D.

1.4 Development and Evaluation Tools

1.4.1 Tool Kit

A Tool Kit contains the hardware essentials you will need to create and use your own BL2100 single-board computer. The items in the Tool Kit and their use are as follows.

• BL2100 User's Manual with schematics (this document).
• Programming cable, used to connect your PC serial port to the BL2100.
• AC adapter, used to power the BL2100. An AC adapter is supplied with tool kits sold in the North American market. If you are using another power supply, it must provide 9 to 36 V DC (13 to 36 V DC if you intend to use the full range of the D/A converter outputs).
• Demonstration Board with pushbutton switches and LEDs. The Demonstration Board can be hooked up to the BL2100 to demonstrate the I/O and the TCP/IP capabilities of the BL2100.
• Wire assembly to connect Demonstration Board to BL2100.
• Plastic enclosure base with mounting screws.
• Screwdriver.
• Rabbit 2000 Processor Easy Reference poster.
• Registration card.

1.4.2 Software

The BL2100 is programmed using version 7.06 or later of Z-World's Dynamic C Premier, an integrated development environment that includes an editor, a C compiler, and a debugger. Library functions provide an easy-to-use interface for the BL2100. Software drivers for TCP/IP, I/O, and serial communication are included with Dynamic C Premier.
