Advantages This PCI Express serial card offers compact, low-profile hardware that integrates with a wide range of desktop motherboards. It supports high-throughput PCIe signaling up to 2.5 Gbit/s and serial communication at standard baud rates, enabling stable data exchange with connected devices. The card is configured for internal host connection, requires minimal installation effort, and includes configurable COM port settings to adapt to different system requirements. Suitable for Connecting legacy serial peripherals such as modems and serial printers Industrial equipment and automation controllers requiring DB9 interfaces Point-of-sale (POS) systems and barcode scanners with serial ports Network appliances and embedded systems that need internal serial I/O Key specifications Interface: PCI Express (PCIe) host interface compatible with x1/x4/x8/x16 slots Serial ports: 2 × DB9 (RS-232 compatible) Maximum throughput: up to 2.5 Gbit/s over PCIe link Serial baud rate support: up to 230,400 bps Form factor: standard and low-profile bracket options included Mounting: internal card for desktop systems Weight: approximately 0.17 kg Certification: CE and FCC compliant How to use Power down the computer and install the card into an available PCIe x1, x4, x8 or x16 slot. Secure the card with the appropriate bracket (standard or low profile) and reconnect power. Boot the system, install any required drivers or software supplied by the host operating system or the manufacturer, and configure COM port parameters (baud rate, parity, stop bits and flow control) as needed in the operating system or application settings. Connect DB9 serial cables from the card to target devices and verify communication using terminal software or device-specific utilities. Usage recommendations Use shielded DB9 cables for longer runs and in electrically noisy environments, set matching baud rate and flow-control settings on both host and device, and install the low-profile bracket only when space constraints require it. For reliable operation in industrial settings, follow grounding and shielding best practices and verify driver compatibility with your operating system before deployment. ## Specifications ### Ports & interfaces | Feature | Value | |---|---| | Serial ports quantity | 2 | | Host interface | PCIe | | Output interface | Serial | ### Other features | Feature | Value | |---|---| | Manual | Yes | | Drivers included | Yes | ### Weight & dimensions | Feature | Value | |---|---| | Weight | 0.17 kg | | Height | 20 mm | | Width | 68 mm | | Depth | 120 mm | ### System requirements | Feature | Value | |---|---| | Windows operating systems supported | Y | ### Design | Feature | Value | |---|---| | Internal | Yes | ### Performance | Feature | Value | |---|---| | Certification | CE, FCC | ### Logistics data | Feature | Value | |---|---| | Harmonized System (HS) code | 84733020 | ### Features | Feature | Value | |---|---| | Data transfer rate (max) | 2.5 Gbit/s | ### Packaging data | Feature | Value | |---|---| | Mounting brackets included | Yes | ## FAQ ### How much does the MANHATTAN PCI Express Serial Card 2x DB9 cost, and is it available for purchase?
