Product information

Description

The StarTech.com PEX4S232485 is a 4-port PCI Express serial combo card that provides two RS232 and two RS422/RS485 ports for expanding serial connectivity on desktop and small form factor PCs. Designed to fit a PCIe expansion slot, the card uses a SystemBase SB16C1052PCI chipset and a 256-byte FIFO buffer to reliably handle serial data streams. Physical dimensions are 125 mm x 70 mm x 20 mm, and the card includes both full-height and low-profile brackets plus a breakout cable for tidy external connections.

Advantages

This single-board solution supports RS-232, RS-422 and RS-485 (2-wire and 4-wire) communication modes, enabling connection to a wide range of serial devices and mixed-protocol environments. The included breakout cable reduces cable clutter and installation time, while the dual bracket design ensures compatibility with full-size and small form factor systems. The onboard FIFO buffer improves data handling under high-throughput or burst conditions.

Suitable for

Connecting legacy RS232 devices such as modems, barcode scanners, and serial printers
Industrial and automation equipment using RS422 or RS485 protocols
POS systems and kiosks requiring multiple serial ports
Embedded or small form factor PCs where additional serial ports are needed

Key specifications

Host interface: PCIe (PCI Express)
Ports: 2 x RS232, 2 x RS422/RS485 (supports RS-485 2-wire and 4-wire modes)
Chipset: SystemBase SB16C1052PCI
FIFO buffer: 256 bytes
Included accessories: breakout cable, full-height and low-profile brackets
Form factor compatibility: full-size and small form factor PCs
Internal card mounting: Yes
Weight: 0.0674 kg
Dimensions: 125 mm x 70 mm x 20 mm

How to use

Power down the PC and insert the PEX4S232485 into an available PCIe slot, then secure the card using the appropriate bracket (full-height or low-profile). Connect the breakout cable to the card and route the cable to your serial devices. Install any required drivers for your operating system; the card supports common Windows versions including Windows 2000 through Windows 7. Configure serial port settings (baud rate, parity, data bits, stop bits, and protocol mode RS232/RS422/RS485) within your application or operating system to match the connected devices.

Usage recommendations

For reliable communication, match serial settings between the PEX4S232485 and each connected device and use shielded cabling where possible in electrically noisy environments. When using RS485 in multi-drop configurations, implement proper termination and biasing resistors to prevent signal reflections. Verify driver compatibility with your specific Windows build before deployment and retain the low-profile bracket if installing in compact systems.
