Rabbit® SBC BL2100 Series


Single-Board Computer

  • 40 sinking/sourcing digital I/O
  • Up to 512K Flash for program and up to 512K SRAM for data
  • 16 digital outputs which can sink/source 200 mA
  • 11 A/D and 4 D/A with 12-bit resolution
  • Up to 4 serial ports: two 3-wire (or one 5-wire) RS-232 and 1 RS-485

The BL2100 series is available in four flexible configurations, which feature 40 digital I/O, 3 RS-232/485 serial ports, and a battery-backup for the real-time clock and SRAM for protected data. In addition, the BL2100 and BL2120 models include 11 channels of 12-bit resolution A/D input and 4 channels of 12-bit D/A output. The BL2100’s 16 digital outputs can sink/ source up to 200 mA and are configurable in Dynamic C, an easy-to-use C environment.

An optional 7-key 122 x 32 graphic display is available as a cost-effective user interface (a panel-mount, water-resistant NEMA 4 version is also available). The BL2100 boards come standard with screw terminals which, can support 14 AWG wiring or other options such as IDC or friction lock headers.

Designed for medium-scale control and monitoring applications, the BL2100 is a high-performance single-board computer that gives OEM designers Ethernet and keypad/display options all in one low-cost package. The BL2100 offers plenty of sinking/sourcing digital I/O with A/D and D/A, providing comprehensive integrated control capabilities in a compact 4.14" x 3.41" (105 mm x 87 mm) form factor. Ethernet models are ideal for remotely monitoring and supervising another programmable system or web-enabling new or existing products. The Ethernet interface is fully supported by software to enable network and Internet connectivity.

  • Optional backlit 122 x 32 pixel graphic display, 7 user-relegendable keys, 7 LEDs
  • 10Base-T Ethernet with RJ-45
  • Optional 512K Flash/512K SRAM
  • 40 sinking/sourcing digital I/O
  • 11 A/D and 4 D/A
  • 4 serial ports
  • Software support enables network connectivity, E-mail, web server

Available in four flexible configurations-two with Ethernet, two without-all BL2100 models feature 40 digital I/O, 3 RS-232/485 serial ports (plus one programming port), Rabbit® 2000 microprocessor at 22.1 MHz, 128K SRAM and 256K Flash (standard), 7 timers, and battery-backed real-time clock. For the most demanding applications, the BL2100 and BL2120 models include 11 channels of 12-bit resolution A/D input and 4 channels of 12-bit D/A output. The BL2100's 16 digital push/pull outputs allow per-point sinking or sourcing, addressing the needs of both the domestic and international markets.

A 7-key 122 x 32 graphic display is available as a cost-effective user interface (a panel-mount, water-resistant NEMA 4 version is also available). Keypad legends are easily modified by customizing printed paper inserts. User-programmable LEDs provide quick-status feedback, and the entire board/display/keypad assembly mounts in an integrated plastic enclosure.

The BL2100 is available as an unenclosed printed circuit board, mounted on a plastic baseplate, in a plastic enclosure with a display, or with a panel-mounted display connected to the board with a flat cable.

Programming the BL2100 Single-Board Computer

Programs are developed using Rabbit's industry-proven Dynamic C® software development system via RS-232 interface. Software libraries and a built-in converter program facilitate display of international characters, bitmap images, and graphic constructs such as circles, lines, and squares. An extensive library of drivers and sample programs is provided, along with royalty-free TCP/IP stack with source. All BL2100 models can be programmed and debugged over Ethernet/Internet using appropriate accessory hardware.
