InLine® PCIe-interfacekaart, 2x RS-232 + 1x parallelpoort

Expand your desktop's connectivity with this PCI Express x1 interface card, adding two RS-232 serial ports and one IEEE 1284 parallel port through a single expansion slot. The MosChip MCS9901CV-AA controller ensures reliable data transfer with 16-byte FIFO buffers and baud rates up to 230.4 Kbps on serial channels, while the parallel port supports EPP/ECP modes for legacy printers and devices.

Advantages

This card brings legacy port support to modern systems, enabling connection of industrial equipment, POS terminals, and older peripherals. The included low-profile bracket allows installation in slim desktops, and PCIe x1 compatibility ensures broad motherboard support. Plug-and-play installation with Windows and Linux drivers simplifies setup, while IRQ sharing and PCI Power Management 1.2 compliance enhance system stability and energy efficiency.
