Dynamode PCI-1P2S PCI Serial Controller Card - 2x RS232 DB-9, 16C550 UART

Add legacy serial connectivity to a modern PCI-equipped desktop. The Dynamode PCI-1P2S is a 2-port PCI serial controller card that fits a standard PCI slot and provides two DB-9 male RS232 serial ports, letting you connect serial devices to systems that no longer include built-in serial ports.

Serial connections remain common in industrial equipment, point-of-sale hardware, lab instruments and older peripherals, and this card bridges that gap for desktop PCs. Built around a 16C550 dual UART design, it supports data transfer of up to 1MB per second per port, and installation is simplified with Plug and Play support for automatic IRQ and DMA allocation.

Ideal for

• Connecting serial-interface industrial or lab equipment to a modern PC
• Point-of-sale systems requiring RS232 connectivity
• Upgrading a desktop that lacks built-in serial ports
• IT technicians supporting legacy hardware

Good to know

This card requires a free standard PCI expansion slot, so confirm your motherboard has one available before purchasing — it will not fit PCI Express-only slots without a separate adapter. The included driver disk should be used during installation to ensure the card is correctly recognised by your operating system.
