Reliable PCI 1 Serial Port Card W-9835-1S for Legacy and Industrial Communication

PCI Serial Expansion for Legacy and Industrial Systems

PCI 1 Serial Port Card W-9835-1S is designed to add one stable serial communication interface to a compatible desktop computer, workstation, or industrial PC through a PCI expansion slot. It provides a practical connection solution for systems that still rely on serial peripherals, control equipment, communication terminals, test devices, and other legacy hardware.

Built around a 16C550-compatible UART architecture, the card includes a 16-byte transmit-and-receive FIFO for efficient data handling. Selectable receive trigger levels, modem control signals, status reporting capability, a programmable baud rate generator, and an on-chip oscillator support flexible integration into different serial communication environments.

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

Technical Specifications

Efficient FIFO-Based Serial Data Handling

The integrated 16-byte FIFO temporarily stores transmitted and received data, helping reduce repeated processor intervention during serial communication. This is useful when connected equipment sends continuous information or when the host system must handle several tasks at the same time.

Selectable receive trigger levels allow the system to respond according to the amount of data held in the FIFO. Together with status reporting capability and modem control signals, this design supports more adaptable communication behavior for industrial, commercial, and legacy-device applications.

Programmable Baud Rate and Fast Serial Communication

A programmable baud rate generator helps configure the card for serial devices using different communication speeds. The listed maximum serial data rate is up to 1 Mbyte/s, making the W-9835-1S suitable for applications that require faster transfer than basic low-speed serial links.

Actual communication performance may depend on the host computer, operating system, driver, cable quality, connected device, and communication settings. Buyers should confirm their target baud rate, protocol, cable length, and peripheral requirements before placing a volume order.

DB9 Male Connector with Optional DB25 Male Configuration

The standard configuration uses a DB9 male serial connector, which is widely used for serial communication equipment. An optional DB25 male version is available for projects that require a different physical connector format.

Before ordering, customers should confirm the required connector, pin assignment, cable type, and connected equipment. Providing these details during the inquiry stage helps reduce compatibility risks and supports faster quotation and configuration confirmation.

Typical B2B Application Scenarios

The PCI 1 Serial Port Card W-9835-1S can be considered for system maintenance, equipment replacement, industrial computer integration, and legacy peripheral connectivity. Recommended application scenarios include:

• Industrial computers and factory control systems

• Point-of-sale terminals and commercial equipment

• Access control and identification systems

• Test instruments and measurement equipment

• Communication terminals and serial data devices

• Barcode equipment and legacy peripherals

• Repair, replacement, and system upgrade projects

Software and System Compatibility Considerations

The listed software environments include DOS, Windows 9x, Windows 2000, Windows NT, Linux, Windows XP, and Windows Vista. Because these are primarily legacy operating systems, customers should verify driver availability and compatibility for the exact system version before purchase.

For accurate evaluation, please provide the motherboard or industrial computer model, PCI slot information, operating system version, connected serial device, required connector, and intended communication settings. Compatibility confirmation is especially important for replacement projects and long-term industrial installations.

Why Choose PCI 1 Serial Port Card W-9835-1S?

W-9835-1S combines a focused one-port design with a 16C550-compatible UART, 16-byte transmit-and-receive FIFO, selectable receive trigger levels, programmable baud rate control, modem control signals, status reporting, and connector flexibility. It is a practical option for buyers who need to maintain serial connectivity on compatible PCI-based systems.

For a faster B2B quotation, send your required quantity, destination country, operating system, motherboard or industrial PC model, preferred DB9 or DB25 connector, application, and expected delivery schedule. These details help confirm configuration, compatibility, packaging, pricing, and lead time for your PCI 1 Serial Port Card W-9835-1S project.
