Product information

Description

The StarTech.com PEX8S1050 is an 8-port PCI Express RS-232 serial adapter card that adds eight DB9 serial ports to a standard desktop or server via a PCIe x1 slot. The card uses a 16C1050-compatible UART, offers per-port speeds up to 921.6 Kbps, and includes 15kV ESD protection. A DB62-to-8x-DB9 breakout cable and mounting hardware are included for straightforward installation and connection of serial peripherals.

Advantages

This PCIe serial card provides eight bi-directional RS-232 DB9 ports with a 256-byte FIFO buffer and support for high baud rates up to 921.6 Kbps per port. It includes configurable pin 9 power (12V/5V/none) with up to 3 A total shared, integrated 15kV ESD protection, and a full-profile PCIe 1x form factor compliant with PCI Express Base Specifications 1.0a/1.1. The package contains an 18" (48 cm) DB62 to 8x DB9 breakout cable and hex nuts for secure DB9 connections.

Suitable for

Connecting serial printers and scanners
Point-of-sale devices (card readers, PIN pads)
Modem and legacy serial communications
Industrial controls and automation equipment
Servers and desktops requiring additional serial ports

How to use

Install the PEX8S1050 into an available PCIe x1 slot in a standard-profile desktop or server. Attach the included DB62-to-8x-DB9 breakout cable to the card and secure DB9 connectors using the supplied hex nuts if desired.
