Advantech 2-Port RS-232/422/485 PCI Express Communication Card w/Surge & Isolation

Designed for robust, reliable serial connectivity in industrial, laboratory, and enterprise environments, the Advantech 2-Port RS-232/422/485 PCI Express Communication Card w/Surge & Isolation delivers flexible dual-port serial expansion for desktops and workstations. This PCIe-based card brings two independent serial channels to life, each of which can be configured for RS-232, RS-422, or RS-485, enabling you to support a wide range of devices—from legacy sensors and instruments to high-density multi-drop networks. The combination of surge protection and galvanic isolation helps protect your host system and connected equipment from voltage spikes, ground loops, and electrical noise that are common in industrial settings, ensuring steady data transfer and reduced downtime.

With its compact yet rugged design, the Advantech PCI Express serial card integrates seamlessly into standard PC chassis, offering a future‑proof upgrade path for serial-heavy applications such as factory automation, point-of-sale systems, data acquisition, telemetry, and communications gateways. The card is supported by comprehensive drivers and utilities for Windows and Linux, simplifying installation and configuration. Whether you are modernizing an existing fleet of devices or building a new, reliable serial communication backbone, this two-port Advantech card provides the performance, protection, and flexibility you need.

• Dual configurable serial ports: Each of the two ports can be set to RS-232, RS-422, or RS-485, allowing you to connect a mix of devices on a single card. This per-port configurability means you can run legacy RS-232 devices alongside multi-drop RS-485 sensors without juggling adapters or multiple expansion cards.
• Flexible, reliable communication: The card supports high‑speed serial data transfer with precise timing and stable baud rate handling. Its design minimizes data loss in environments with electrical noise, long cable runs, or clustered devices, ensuring consistent performance for critical applications such as CNC controls, barcode systems, and remote telemetry.
• Surge protection and isolation: Built‑in surge suppression and galvanic isolation safeguard both the host computer and the connected serial devices from voltage spikes and ground potential differences. This protection is especially valuable in factory floors, U.S.B. powder-coated environments, and other industrial spaces where electrical disturbances are common.
• Industrial‑grade durability and compatibility: The PCI Express form factor is designed for easy integration into standard desktops and workstations, with a robust enclosure intended to withstand challenging environments. The card is compatible with a broad range of operating systems and supports standard driver stacks, making it suitable for mixed-OS deployments in manufacturing, automation, or data-center edge devices.
• Comprehensive software support: The card ships with drivers and configuration utilities for Windows and Linux, plus documentation and APIs that help developers integrate serial communications into custom applications, SCADA systems, or IoT gateways. The software tools enable straightforward port configuration, baud rate selection, parity settings, stop bits, flow control, and alarm logging to streamline deployment and ongoing maintenance.
