(URL: http://lanpoint.com/.html)

The PCI-20001C-2A is a customizable data acquisition board with 32 points of fully buffered digital I/O already on board. These points are arranged in four ports of 8 bits (1 byte) each, which can be configured via software for either input or output use. In addition, you can expand the I/O capabilities of the board beyond the built-in digital channels by adding up to three plug-in option modules. The option modules provide analog input, analog output, digital I/O, counter/timer, quadrature decoder, high-speed triggering, alarm, and simultaneous sample/hold functions.

The PCI-20001C-2A interfaces directly with the internal bus of ISA computers. It provides the mounting space, power, and inter-module communications required to support three option modules. All power is derived from the +5V, PC power supply. A DC/DC power converter on the board generates ±5V for the use of the modules. Digital, sync, and analog signals pass between modules via the on-board Intelligent Instrumentation Interface (I3) Bus.

• 32 Digital I/O Points Included On-Board
• Additional I/O Functionality Provided by Plug-In Option Modules
• Supports Up to Three I/O Modules per Board
• On-Board I3 Bus Allows Digital, Analog and Timing Signals to Be Passed Between Modules
