PCI Express Serial Card StarTech Dual Port PEX2S1050 Low Profile

Description

Product Overview

The StarTech PCI Express dual port serial card is engineered to meet the rigorous demands of modern industrial and commercial environments. Designed to comply with the PCI Express 1.0a specification, this card fits seamlessly into 1x, 2x, 4x, 8x and 16x slots, providing flexibility for a wide range of system configurations. Its compact dimensions—3.09 x 3.6 x 0.6 inches—make it ideal for low‑profile chassis, while the standard‑profile bracket ensures easy installation in larger cases. The card features two DB9 connectors, each supporting reliable serial communication at data rates up to 460 Kbps, which is sufficient for most POS, manufacturing control, and security device applications.

Constructed from high‑quality materials, the card offers robust electrical performance and durability. The copper‑clad PCB, reinforced with a protective coating, helps to minimize signal interference and maintain consistent data integrity even in electrically noisy environments. The integrated IRQ sharing capability simplifies system configuration, allowing multiple serial devices to coexist without conflict. Additionally, the card is fully plug‑and‑play compatible with Windows operating systems, requiring no additional drivers for basic operation, which reduces deployment time and technical overhead.

Beyond its core functionality, the card includes a suite of features that enhance its value proposition. The low‑profile form factor reduces the overall footprint inside the computer, freeing up space for additional components or cooling solutions. The optional low‑profile bracket further reduces height, making the card suitable for slim desktop or embedded systems. The device is also backed by StarTech’s reputation for quality and reliability, with a track record of delivering products that meet or exceed industry standards.

In terms of specifications, the card weighs just 2.15 ounces, making it lightweight yet sturdy. It operates on a single AAAA battery, ensuring that the serial ports remain powered even when the host system is shut down, a critical feature for data logging and remote monitoring scenarios. The product carries the model number PEX2S1050 and is listed under the ASIN B01N25W4P9, reflecting its availability and compatibility with major e‑commerce platforms.

Overall, the StarTech PCI Express dual port serial card combines performance, flexibility, and ease of use into a single solution that addresses the needs of diverse industries, from retail point‑of‑sale terminals to industrial automation controllers.

Usage

This serial card excels in environments where reliable, high‑speed serial communication is essential. Retail businesses can deploy it in POS terminals to connect barcode scanners, receipt printers, and cash drawers, ensuring swift transaction processing. In manufacturing settings, the card can interface with programmable logic controllers (PLCs), CNC machines, and sensor arrays, providing a stable link for real‑time data exchange and equipment monitoring.

Security installations benefit from the card’s ability to connect to access control panels, alarm systems, and surveillance devices that rely on serial protocols. Its low‑profile design allows integration into compact security consoles without sacrificing performance. Additionally, the card’s plug‑and‑play nature makes it suitable for field technicians who need to quickly upgrade or replace serial interfaces on existing hardware without extensive reconfiguration.

FAQ

What operating systems are supported?

The card is fully compatible with Windows operating systems, including Windows 10, 8, and 7. It works with standard drivers provided by the OS, so no additional software is required for basic functionality.

Can the card be used in a low‑profile chassis?

Yes. The card’s dimensions and optional low‑profile bracket make it suitable for slim desktop or embedded systems where height is limited. The standard bracket is also included for larger cases.

Is the card hot‑swappable?

While the card supports plug‑and‑play installation, it is not hot‑swappable. It should be installed with the system powered down to avoid potential damage to the PCI Express slot.

What is the maximum cable length supported?

For reliable data transmission at 460 Kbps, a cable length of up to 50 meters (approximately 164 feet) is recommended. Longer runs may require repeaters or signal boosters to maintain integrity.

Does the card require external power?

The card draws power from the host system’s PCI Express slot and uses a single AAAA battery to keep the serial ports powered when the system is off, ensuring continuous operation for devices that need standby power.
