BL2000 Single-Board Computer
Models BL2000, BL2010, BL2020, BL2030
Description
The BL2000 gives OEM designers optional Ethernet connectivity in a low-cost, high-performance single-board computer. These compact boards are rich with the digital I/O, A/D, and D/A designers need for embedded control and monitoring applications, and the BL2000's compact board size of 4.15" x 3.43" (105 mm x 87 mm) allows for easy integration. Ethernet models are ideal for remotely monitoring and supervising another programmable system or web-enabling new or existing products.
Features
- 10Base-T Ethernet with RJ-45
- Up to 28 digital I/O
- Up to 11 A/D and 2 D/A
- 4 serial ports
- Optional 512K Flash / 512K SRAM
- Onboard relay
The BL2000 models are available in four configurations-two with Ethernet, two without-and feature up to 28 digital I/O (including 5 or 7 dual-purpose analog or digital inputs), 3 RS-232/485 serial ports (plus one programming port), Rabbit® 2000 microprocessor at 22.1 MHz, 128K SRAM and 256K Flash, onboard SPDT relay, LEDs, 7 timers, and battery-backed real-time clock.
For the most demanding applications, the BL2000 and BL2020 models include 4 channels of 12-bit resolution A/D input, 5 channels of dual-purpose input, and 2 channels of 12-bit D/A output. For applications not requiring high-resolution analog I/O, the BL2010 and BL2030 offer 4 channels of 10-bit resolution A/D input and 7 channels of dual-purpose input. The dual-purpose inputs are software configurable as analog inputs or programmable-threshold digital inputs.
All BL2000 models can be programmed and debugged over Ethernet/Internet using appropriate accessory hardware. Systems with built-in 10Base-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.
Programming the BL2000 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. All BL2000 models can be programmed and debugged over Ethernet/Internet using appropriate accessory hardware.
