Easily add four RS-232 interfaces via PCIe x1Four serial ports immediately available: Add RS-232 (9-pin) via PCIe x1 to desktops and servers.
Stable communication with legacy devices: 256-byte FIFO per port and up to 230.4 kb/s for reliable data transfer.
Easy integration into existing software: Compatible with 16C450/16C550, hardware/software flow control, and flexible data, parity, and stop bit settings.
Flexible upgrade via PCIe x1: single-lane operation for broad motherboard compatibility.
This PCIe interface card adds four serial RS-232 ports to your PC. It complies with the PCI Express base specification 1.1 and uses an x1 lane. The 256-byte FIFO buffers per port support sustained transfer up to 230.4 kb/s and facilitate reliable connection of serial peripherals.
Especially in professional IT environments, on-site installations, and service deployments, the card facilitates continued operation of existing measuring instruments, POS systems, terminals, modems, or PLCs within existing infrastructures of companies and public institutions.
