Introduction

Overview

A Smart Multiport Async Solution

The CP-104UL board is designed for the 32-bit PCI bus with Plug and Play feature. These boards

offer 4 RS-232 serial ports for connecting terminals, modems, printers, scanners, cash registers,

bar code readers, keypads, numeric displays, electrical scales, data acquisition equipment, and

many other serial devices for the PC and compatible systems. With its well-designed and fine-

tuned device driver, the CP-104UL boards make full use of the 128 byte Tx/Rx FIFO and on-chip

H/W and S/W flow control, which makes possible transferring data without loss at transmission

speeds up to 921.6Kbps. These boards offer a reliable and high performance solution for serial

multiport communications.

Board Applications

The CP-104UL Board can be used with many applications, including:

z Internet/Intranet Connections

z Remote Access Applications

z Multi-user Applications

z Industrial Automation

z Office Automation

z Telecommunications

z PC-based Vending Machines or Kiosk Systems

z POS (Point-of-Sale) Systems

PCI Solution

The CP-104UL board complies with PCI Spec. 2.1, and does not use either switches or jumpers.

The hardware configuration for the IRQ and Memory addresses is automatically assigned by the

PCI BIOS. Hence, the board MUST be plugged in before installing the driver software. For more

PCI information, refer to the Technical Reference Appendix.

Surge Protection

To prevent the board from being damaged by lightning or high potential voltage, TVSS (Transient

Voltage Surge Suppressor) technologies with 15KV ESD protection are used in the CP-104UL

board. This is required for harsh environments, such as in factory settings, under severe weather

conditions, such as lightning, or other high interference situations.
