Reliable PCI Express 8-Port RS-232 Serial Card W-958E-8S for Multi-Port Communication

Overview

The W-958E-8S PCI Express 8 port RS-232 card is designed to expand a computer with up to eight RS232 serial ports through a single PCI Express x1 slot. It is a practical choice for systems that need multiple serial connections while preserving a compact host interface. With PCI-Express 2.0 compliance, backward compatibility with PCI-Express 1.1 and throughput up to 2.5Gbps on the single-lane PCIe interface, the card provides a clear path for adding legacy serial connectivity to compatible computer platforms.

Each serial port integrates an on-chip 256-byte FIFO in both transmit and receive paths. This architecture helps the host system manage serial data efficiently when several connected devices are communicating. The card also supports a re-map function for legacy ports, making it suitable for applications where traditional serial port addressing remains important.

Key Features of W-958E-8S PCI Express 8-Port RS-232 Card

Technical Specifications

System Compatibility

The W-958E-8S is intended for computer systems that provide a compatible PCI Express expansion slot. Supported operating systems listed for this card include DOS, Windows 8.1, Windows 7, Windows Vista, Windows XP, Windows 2000, Windows Server 2003-2008 in 32-bit and 64-bit environments, Linux, and Mac OS/X 10.5.

For Windows-based deployments, WHQL software drivers are available. Before purchasing for a new or upgraded system, buyers should confirm the required operating system version, available PCIe slot and application environment to ensure the card matches the target installation.

Why Choose an 8-Port PCIe RS232 Card?

A multi-port serial card can reduce the need for multiple separate adapters when a host computer must communicate with several RS232 devices. The W-958E-8S combines eight serial ports with one PCIe x1 connection, helping system builders organize serial expansion through a single add-on card.

Its wide specified operating temperature range also gives buyers a clearly defined environmental parameter for equipment planning. The included 8-port serial fan-out cable brings the card's serial connections out from the installed board, while the user manual and software driver CD support setup and deployment.

Typical Integration Considerations

When evaluating the W-958E-8S for a B2B project, procurement teams and system integrators can compare the following points with their application requirements:

• Number of required RS232 connections: up to eight ports.

• Host interface: PCI Express x1.

• PCIe compatibility: Specification 2.0 with backward compatibility to 1.1.

• Required operating temperature: -40°C to 85°C.

• Driver environment: listed Windows, DOS, Linux and Mac OS/X compatibility.

• Physical installation space: approximately 100 mm × 120.0 mm × 21.5 mm.

• Cabling requirement: one RS232 8-port serial fan-out cable is included.
