2PORT PCI EXPRESS SERIAL CARD

The StarTech.com 2-Port PCIe Serial Card adds two RS232 DB9 serial ports to a low- or full-profile desktop computer, making it suitable for users connecting legacy serial devices through a PCI Express slot.

Recommended For

• Desktop or server operators connecting two RS-232 devices—such as barcode scanners, serial printers, or cash registers—to a system without built-in serial ports.
• Manufacturing or process-control teams adding two serial connections to a PCIe-equipped PC used with CNC machinery or other legacy equipment.
• POS and hospitality operators who need a stationary PC to connect serial receipt printers, barcode scanners, card readers, or scales.
• Security or facilities teams connecting RS-232 devices such as access panels, card readers, UPS controls, or building-control equipment to a desktop or server.
• Small-form-factor PC builders who have a compatible PCIe slot and need two internal serial ports; the card includes a low-profile bracket option.

Real-World Use Scenarios

• A shop-floor PC needs to exchange data with RS-232 CNC or process-control equipment; adding the card can provide the serial connection while the machine continues using compatible legacy software and cabling.
• A point-of-sale workstation must keep using serial receipt printers, barcode scanners, card readers, or scales; the two ports let it connect compatible RS-232 devices without relying on a motherboard serial port.
• A business is replacing an older PC but keeping serial peripherals such as a barcode scanner and printer; the card adds two DB9 connections to the newer desktop, provided the devices use RS-232 and the required drivers and cables are compatible.
• A facility PC needs a wired serial link to compatible access-control readers, surveillance equipment, or UPS controls; an available PCIe slot can add the RS-232 ports needed to keep those devices connected.
• A building-management workstation needs to communicate with compatible serial lighting or temperature-control equipment; the card can add a direct RS-232 connection, though the device’s protocol and cable pinout must match.
