Description

StarTech PCI2S4851050 2-Port RS422/485 Serial Adapter Card

Overview

The StarTech PCI2S4851050 provides a reliable method to add two RS422 or RS485 serial communication ports to a desktop computer via a standard PCI or PCI-X slot. This adapter card is essential for integrating legacy serial devices or industrial automation equipment into modern systems, particularly in environments requiring robust serial communication like manufacturing floors or security control rooms. The PCI2S4851050 supports data transfer rates up to 128 Kbps, ensuring efficient communication for demanding applications.

Compatibility

This card is compatible with systems utilizing a PCI or PCI-X bus, supporting both 5V and 3.3V signaling. It is designed to work with Windows operating systems, enabling connectivity for a wide range of serial devices. The integrated DB-9 connectors ensure broad compatibility with standard serial cabling. It is suitable for connecting to industrial controllers, POS systems, or serial-based security devices that require RS422 or RS485 protocols.

Installation Notes

The PCI2S4851050 includes both standard and low-profile brackets, allowing installation in full-height or slimline computer chassis. It operates within an ambient temperature range of -10°C to 80°C, making it suitable for various deployment environments. The card utilizes a 16C1050 UART with a 256-byte FIFO buffer, which helps to improve data throughput and reduce CPU load by minimizing interrupt requests.
