How to Use This Guide
This manual is designed to help you use the PCI-6308. It describes how to
modify and control various functions on the PCI-6308 card to meet your
requirements. It is divided into three chapters:
♦Chapter 1,"Introduction", gives an overview of the product features,
applications, and specifications.
♦Chapter 2, "Installation", describes how to install the 723X products.
The PCB layout is shown, the connectors specifications, and the notes for
installation are described.
♦Chapter 3, "Register Format", describes details on-board register
format. It is very useful to understand the lowest level of controlling the
boards.
♦Chapter 4, "Operation Theorem", describes more details about the
operation of DIO and COS system.
♦Chapter 5, "C/C++ Library", describes the functions in the DOS C/C++
Library and Windows 95 DLL.

Introduction
This manual describes the contents of PCI-723X family products. Include:
♦PCI-7230: Isolated 16-CH DI and 16-CH DI Card
♦PCI-7233: Isolated 32-CH DI Card with COS detection
♦PCI-7233H: Isolated High-speed 32-CH DI Card with COS
♦PCI-7234: Isolated 32-CH DO Card
♦cPCI-7230: Isolated 16-CH DI and 16-CH DI Module for 3U
CompactPCI
These products are with high isolation voltage and 32 DI or DO channels. The
high isolation voltage protects your computer against damage caused by
accidental contact with high external voltage and eliminates troublesome
ground loops.
The PCI-7230/cPCI-7230 provides 32 isolated digital I/O, 16 Isolated inputs
and 16 isolated outputs. The isolated I/O channels are isolated to 5,000 Vrms
(excluding cables).
The PCI-7233 provides 32 isolated digital input channels with COS
(change-of-state detection). The high speed version PCI-7233H provides
32-CH isolated digital input .The isolation voltage of PCI-7233H is high up to
2,500 Vrms (excluding cables).
The PCI-7234 provides 32 isolated digital output (Darlington transistor)
channels. The isolation voltage is high up to 5,000 Vrms (excluding cables),
both channel-to-channel and channel-to-computer.
ThePCI-7230/7233/7234 use ASIC PCI controller to interface the board to the
PCI bus. The ASIC fully implement the PCI local bus specification Rev 2.1. All
bus relative configurations, such as base memory address and interrupt

2•Introduction
assignment, are automatically controlled by BIOS software. It does not need
any user interaction and pre-study for the configurations. This removes the
burden of searching for a conflict-free configuration, which can be very
time-consuming and difficult with some other bus standards.
