Reliable serial communication: Two independent RS-232 ports enable the connection of classic peripheral devices to modern PCIe systems.
Stable data transfer even under high load: 256-byte FIFO buffers for transmit and receive data ensure uninterrupted communication.
Versatile compatibility: Supports baud rates up to 921,600 bps as well as common RS-232 signals – ideal for industry, control technology, and IT.
Flexible system integration: Suitable for compact industrial PCs or desktop systems thanks to standard and low-profile slot brackets.
Broad operating system compatibility: Supports Windows versions 7 and above, current Windows servers, and Linux from kernel 2.6.30 – driver CD included.
The InLine® PCIe 2-Port RS-232 Card is the professional solution for expanding modern computers with classic serial interfaces. Equipped with two D-Sub 9 connectors, the card ensures reliable RS-232 communication via the CH382L controller. The card is the ideal choice, especially for industrial applications, mechanical engineering, or connecting measuring and control devices.
Thanks to flexibly adjustable baud rates from 50 to 921,600 bps and extensive signal sets (TXD, RXD, RTS, CTS, DTR, DSR, DCD, RI), the card is extremely versatile. The integrated 256-byte FIFO buffer ensures stable and high-performance data transmission – even with continuous communication or high data volumes.
The PCIe x1 interface allows for easy integration into modern systems and is backward compatible with older PCIe versions. The included low-profile slot bracket allows the card to be installed in both standard and compact enclosures. Additional ESD protection up to ±15 kV protects connected devices from electrostatic discharge.
Drivers for Windows (7 to 11, Server from 2008 R2) and support for Linux systems from kernel 2.6.30 round off the overall package. With its stable design, broad OS compatibility, and professional features, this card is a reliable tool for anyone who relies on classic serial communication.
