User’s Manual 1
1. INTRODUCTION
The BL2600 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. The
BL2600 is ideal for both discrete manufacturing and process-
control applications.
A Rabbit®3000 microprocessor operating at up to 44.2 MHz
provides fast data processing with 10/100Base-T Ethernet con-
nectivity. Serial flash options support a full directory file struc-
tures to maximize remote access control and programmability.
The I/O can be expanded with RabbitNet peripheral cards.
1.1 BL2600 Description
Throughout this manual, the term BL2600 refers to the complete series of BL2600 single-
board computers unless other production models are referred to specifically.
The BL2600 is an advanced single-board computer that incorporates the powerful Rabbit
3000 microprocessor, flash memory, serial flash options, static RAM, digital I/O ports,
A/D converter inputs, D/A converter outputs, RS-232/RS-485 serial ports, and a
10/100Base-T Ethernet port.
1.2 BL2600 Features
•Rabbit®3000 microprocessor operating at 29.4 MHz or 44.2 MHz.
•Dual-entry IDC through-hole I/O header sockets allow header mounting on either side
of the BL2600 board
•Industry-standard friction-lock connectors for power-supply wiring harness.
•512K static RAM and 512K flash memory standard.
•36 digital I/O: 16 protected digital inputs, 4 high-current digital outputs software-
configurable as sinking or sourcing, and 16 I/O individually software-configurable as
inputs or sinking outputs.
•12 analog channels: eight 11-bit A/D converter inputs, four 12-bit D/A converter 0–10 V
or ±10 V buffered outputs.

2SBC BL2600
•One RJ-45 Ethernet port compliant with IEEE 802.3 standard for 10/100Base-T
Ethernet protocol.
•Up to 5 serial ports:
Three serial ports (2 RS-232 or 1 RS-232 with RTS/CTS, 1 RS-485 or RS-232).
Two RabbitNet™ expansion ports multiplexed from one serial port.
One serial port dedicated to programming/debugging.
•Provision to install optional SF1000 serial flash, other memory options have provision
for removable memory cards.
•Battery-backed real-time clock.
•Watchdog supervisor.
Two BL2600 models are available. Their standard features are summarized in Table 1.
Additional memory and clock speed options are available, and are described in
Section 1.2.2.
The BL2600 consists of a main board with a RabbitCore module. Refer to the RabbitCore
module manuals, available on the Web site, for more information on the RabbitCore mod-
ules, including their schematics.
The BL2600 is programmed over a standard PC serial port through a programming cable
supplied with the Tool Kit, and can also be programed through a USB port with an
RS-232/USB converter, or over an Ethernet with the RabbitLink (both available from Rabbit).
Appendix A provides detailed specifications.

1.2.1 Connector Options
In addition to the standard polarized friction-lock connectors supplied on BL2600 boards,
dual-entry 0.1" IDC sockets can be used to connect to the BL2600 either from the top or
the bottom.
1.2.2 Memory and Clock Speed Options
In addition to the two standard production models of the BL2600, the concept of pairing a
RabbitCore module with the BL2600 “motherboard” allows for additional versions of the
BL2600 to be offered for custom orders involving nominal lead times. These additional
versions and their part numbers are listed below.
Check the Web site or contact your Digi sales representative or authorized distributor for
more information.

1.3 Development and Evaluation Tools
1.3.1 Tool Kit
A Tool Kit contains the hardware essentials you will need to use your own BL2600 single-
board computer. The items in the Tool Kit and their use are as follows.
•Getting Started instructions.
•Dynamic C CD-ROM, with complete product documentation on disk.
•Programming cable, used to connect your PC serial port to the BL2600.
•Universal AC adapter, 12 V DC, 1 A (includes Canada/Japan/U.S., Australia/N.Z.,
U.K., and European style plugs). If you are using another power supply, it must provide
9 to 36 V DC at 12 W .
•Stand-offs to serve as legs for the BL2600 board during development.
•Demonstration Board with pushbutton switches and LEDs. The Demonstration Board
can be hooked up to the BL2600 to demonstrate the I/O and the TCP/IP capabilities of
the BL2600.
•Wire assembly to connect Demonstration Board to BL2600.
•Connector pins and parts to build your own wire assemblies: 0.1" crimp terminals;
0.156" crimp terminals; 1 × 4, 1 × 10, and 1 × 13 friction-lock connectors.
