Easily add four serial ports via PCIFour ports for existing peripherals: Connect 4x 9-pin serial devices simultaneously.
Fast integration into the PC: Automatic IRQ and I/O assignment and PCI IRQ sharing.
Stable communication under load: 16C550-compatible UARTs with 256-byte FIFO.
Flexible settings: Hardware and software flow control and 5-9-bit formats.
Wide operating system support: Windows 2000 to 7 (32/64-bit) and Linux kernel from 2.6.14.
With this PCI interface card, you add four 9-pin serial ports to desktop PCs to continue using proven devices such as modems, IR receivers, data cables, or ISDN systems. Setup is via the 32-bit PCI slot, resources such as IRQ and I/O addresses are assigned automatically. 16C550-compatible UARTs with 256-byte FIFO support stable data transfers up to 115.2 kb/s and reduce system load during continuous transmission.
In professional IT environments, for on-site installations and in service deployments, the card enables reliable operation of serial measurement, control, and automation technology in existing infrastructures of companies and public institutions.
