1. I
NTRODUCTION
The BL2000 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. A
Rabbit
®
2000 microprocessor operating at 22.1 MHz provides
fast data processing. An optional plastic enclosure is available,
and may be wall-mounted or panel-mounted.
1.1 BL2000 Description
The BL2000 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, an SPDT relay output, and a 10Base-T Ethernet port.
