Compact PCI 1 Serial Port Card (Low Profile) W-9835-1S-L

Reliable Serial Port Expansion for Compact Computer Systems

PCI 1 Serial Port Card (Low Profile) W-9835-1S-L is designed for computer systems that require an additional serial communication interface through an available PCI expansion slot. Its low-profile structure makes it suitable for slim desktop computers, compact workstations, embedded computers, industrial control systems, and other installations where internal chassis space is limited.

The card provides one dedicated serial port for connecting compatible peripheral equipment. It is particularly useful for system builders, equipment maintenance companies, industrial integrators, computer repair providers, and distributors that continue to support PCI-based computer platforms.

Instead of replacing an entire computer because a serial port is unavailable, businesses can install this expansion card to maintain communication with existing serial devices. This makes the product suitable for system upgrades, equipment replacement projects, production-line maintenance, and commercial computer assembly.

Key Features of W-9835-1S-L Serial Port Card

Technical Specifications

Low-Profile Design for Space-Restricted Installations

The low-profile construction is one of the main advantages of W-9835-1S-L. It allows the card to be installed in compact computer enclosures where a standard full-height expansion card may not fit. This makes it suitable for slim office computers, embedded systems, point-of-sale terminals, industrial workstations, and customized computer assemblies.

Before ordering, buyers should confirm the available internal space, bracket format, motherboard layout, and PCI slot position. Mechanical compatibility is especially important when the card will be installed in compact chassis designs with limited clearance.

Single-Port Configuration for Dedicated Equipment Connections

The single-port configuration is suitable for systems that need one dedicated serial connection without adding unnecessary interfaces. This can simplify installation, reduce unused hardware, and support standardized computer configurations in projects where each workstation connects to one serial device.

For distributors and system integrators, the focused one-port design can meet replacement and assembly requirements for customers operating established serial equipment. It may also be used when upgrading older computers that no longer provide the required built-in serial interface.

Serial Communication Support for Commercial and Industrial Equipment

Many commercial and industrial devices continue to use serial communication because the equipment remains stable, functional, and integrated into existing workflows. W-9835-1S-L provides a practical connection option for compatible PCI-based computers used in maintenance, production, testing, data collection, and equipment-control environments.

The integrated 16-byte FIFO helps buffer transmitted and received data during communication. Its on-chip oscillator and software-programmable mode selection further support practical system integration when the card is used with compatible hardware, software, and drivers.

Typical Application Scenarios

W-9835-1S-L may be considered for compatible computer systems connected to:

• Industrial control and monitoring equipment

• Point-of-sale and commercial terminal systems

• Barcode scanners and data-collection devices

• Laboratory and testing instruments

• Access-control and attendance equipment

• Legacy printers and communication terminals

• Embedded computers and compact workstations

• Computer maintenance and replacement projects

Actual suitability depends on the connected device, communication interface, operating system, driver support, software configuration, and mechanical installation conditions.

Installation and Compatibility Checklist

Before installing the card, power off the computer and confirm that the motherboard provides a compatible conventional PCI slot. PCI and PCI Express are different expansion interfaces, so buyers should not assume that the card can be installed in a PCI Express slot.

Check the chassis clearance and low-profile bracket format before securing the card. After installation, use the appropriate driver and configure the communication settings required by the connected serial equipment.

Buyers should verify the following information before placing an order:

• Computer or motherboard model

• Available expansion-slot type

• Chassis size and bracket requirements

• Operating system and version

• Connected serial equipment

• Required communication settings

• Driver and software requirements

Information to Include in Your B2B Inquiry

To receive a more accurate compatibility review and quotation, distributors, system builders, repair providers, and equipment integrators are advised to provide detailed project information.
