Description
The BL2500 single-board computer gives OEM designers extremely low-cost embedded control for high-volume
applications such as product control, factory equipment control, access control, HVAC, and vending machines.
Two standard models—one with Ethernet, one without—feature the
Rabbit® 3000 microprocessor
at 29.4 MHz,
with 256K Flash and 128K SRAM (standard).

RabbitNet expansion ports enable a modular and expandable embedded control system whose configuration of
expansion cards can be tailored to a large variety of demanding real-time control, display, and data-acquisition
applications. A typical RabbitNet system consists of a master single-board computer and one or more peripheral
cards. A high-performance Rabbit 3000 or
Rabbit® 2000 microprocessor
on the master provides fast data
processing, and the master SBC also provides the DCIN and +5 V power for the peripheral cards.
Onboard Features
The BL2500's compact board size of 3.95" × 3.95" (100 mm × 100 mm) is easily mountable in standard 100 mm
DIN rail trays. External connections via polarized locking industry standard Molex® type connectors enable rapid
assembly with wire harnesses. These connectors also provide dependable cable harness connectivity to I/O.
Future expansion boards (including A/D, D/A, digital I/O, and keypad/display) will be available which interface via
the two multiplexed SPI RS-422 ports.
The BL2500 provides 24 rugged digital I/O (plus 1 A/D input and 2 D/A outputs) along with 4 LEDs (3 yellow and
1 extra bright red). The 8 industrialized open-collector sinking outputs can easily switch up to 200 mA of inductive
loads such as relays and solenoids with protection from inductive kickback. Of the 16 digital inputs, 15 are fully
protected to ±36 V.
Six serial ports are included to support external communication. Two ports are connected to standard full-duplex
RS-232 circuitry. One port is connected to rugged RS-485 differential pair signaling circuitry-allowing for industry
standard multi-drop RS-485 networks. One port, designed to allow serial expansion, is multiplexed through two
very high-speed (>1Mbit/sec capability) SPI ports with each line going through RS-422 differential pair signaling.
The SPI ports connect to RJ-45 connectors (accepting standard category 5 cabling) for ease of connectivity. One
serial port is a 3.3 V CMOS level port that can either be asynchronous or clocked and one CMOS-compatible
serial port is dedicated to programming/debugging.
The optional Ethernet interface (10 Mbps or 10/100 Mbps) allows easy connection to local networks or the
Internet. Powerful software allows TCP/IP communication including e-mail and serving of web pages. Remote
program development and loading via a network or the Internet is supported using appropriate accessory
hardware
Programming the BL2500 Single-Board Computer
Programs are developed using Rabbit's industry-proven
Dynamic C®
software development system. An
extensive library of drivers and sample programs is provided, along with royalty-free TCP/IP stack with source.
Systems with built-in 10Base-T or 10/100Base-T Ethernet can be directly controlled and monitored across
networks or the Internet, and can also open sockets to remote devices, serve Web pages, or send e-mail. All
BL2500 models can be programmed and debugged over Ethernet/Internet using appropriate accessory
hardware.
