Product information

Description

The StarTech.com PEX2S1P553B is a low-profile PCI Express serial/parallel combo card that adds two RS-232 serial ports and one parallel (printer) port to a desktop or embedded system via a single PCIe expansion slot. The card uses a single breakout cable connector to present all three external ports and includes both low-profile and full-height brackets for flexible installation. Built with a native single-chip design, it delivers improved throughput and reduced CPU load compared with bridge-chip solutions and is compatible with a wide range of operating systems.

Advantages

The PEX2S1P553B provides a space-efficient, single-slot solution for adding legacy serial and parallel ports, with a breakout cable that prevents crowded I/O connectors. Its native single-chip architecture reduces CPU utilization and improves reliability, while the low-profile form factor plus optional full-height bracket enables installation in standard and slim systems. The card supports broad OS compatibility, including 32- and 64-bit Windows versions, Linux, macOS and DOS.

Suitable for

Adding RS-232 serial ports for industrial equipment, modems, barcode scanners or POS systems
Providing a parallel printer port for legacy printers and devices
Installing in space-constrained small-form-factor or embedded PCs
Upgrading systems that require reliable serial/parallel connectivity across multiple operating systems

Key specifications

Model: StarTech.com PEX2S1P553B
Interface: PCI Express (PCIe) host interface
Ports: 2 x RS-232 serial, 1 x parallel
Baud rate: up to 230.4 Kbit/s
FIFO: 256 B
Form factor: low-profile (half-height) with optional full-height bracket
Certifications: CE, FCC, REACH
Weight: 0.225 kg
Colour: Black, Silver

How to use

Install the card into an available PCIe x1 (or larger) expansion slot on the host computer, secure the chosen bracket (low-profile or full-height), and route the included breakout cable to the external devices. Connect serial devices to the two RS-232 connectors and a parallel device to the parallel connector on the breakout cable. After hardware installation, power on the system and install drivers if the operating system does not provide native support. Configure port settings (baud rate, parity, stop bits) in the operating system or application as required by the connected devices.

Usage recommendations

For optimal performance, use quality shielded cables for serial and parallel connections and verify driver compatibility with your OS version. If connecting to industrial equipment, confirm signal levels and grounding to prevent communication errors. Keep the breakout cable connection accessible for maintenance when installed in embedded or space-limited systems.
