Description

StarTech PEX8S1050 8-Port PCI Express RS-232 Serial Adapter Card

Overview

The StarTech PEX8S1050 is a PCI Express x1 serial adapter card designed to add eight RS-232 ports to a system. This card is ideal for connecting legacy serial devices such as barcode scanners, industrial automation equipment, or point-of-sale systems to modern computers that may lack native serial ports. The 16C1050 UART compatibility ensures broad device support, and the 15kV ESD protection safeguards connected equipment.

Compatibility

This adapter card is compatible with standard PCI Express x1 slots. It supports Windows and Windows Server operating systems. The 16C1050 UART provides compatibility with a wide range of serial devices and industrial control systems. The card is designed for standard profile systems but can be used in full-height bays with the appropriate chassis.

Installation Notes

The StarTech PEX8S1050 features 15kV ESD protection on all signals, protecting both the card and connected devices from electrostatic discharge. It supports configurable power output on Pin 9 (12V DC, 5V DC, or None), which is crucial for powering certain serial peripherals without requiring a separate power source. The maximum shared current across all ports is 3A. The card operates within a temperature range of 0°C to 55°C (32°F to 131°F).
