InLine® Interface card, 2x serial RS-232, PCIe, AX99100, low-profile content_copy

Two RS-232 interfaces via PCIe: Ideal for connecting older serial devices such as modems, measurement systems or industrial hardware.
Full protocol support: Supports various data formats, parity types and freely configurable baud rates.
Integrated flow control and 256-byte FIFO: Stable data transmission thanks to hardware/software control and large buffers for professional applications.
Compatible with Windows & Linux: Supports Windows XP, Server 2003 and Linux from kernel 2.6.x – easy driver integration.
Low-profile & full-profile compatible: Includes both slot brackets for full flexibility when installing in different types of enclosures.
With the InLine® PCIe interface card with two RS-232 ports, you can bring classic serial interfaces back into modern PC systems. Perfect for anyone who continues to rely on devices with COM ports – for example, in measurement technology, cash register solutions or industrial control systems.
The card uses the proven ASIX AX99100 chipset for stable and reliable communication. It supports a transfer speed of up to 115,200 bps, a wide range of parity types and bit formats, as well as flow control via hardware or software. A large 256-byte FIFO buffer on each channel prevents data loss even under high loads.
The low-profile bezel supplied makes the card suitable not only for standard housings but also for compact form factors. Thanks to support for current Windows and Linux systems, installation is extremely easy.
Whether for retro technology, machine connection or diagnostic hardware, this interface card is the ideal solution for anyone who continues to rely on RS-232.
