Inline PCIe Serial Card, 4 Port RS-232 Interface, D-Sub 9, CH384L, Low Profile Brackets, UART Interface, High Data Rate, 76619E

The InLine PCIe 4-Port RS-232 Card is the ideal solution for expanding modern PCs and industrial applications with four additional serial ports. Each of the four ports uses the proven D-Sub 9 format and supports a wide range of serial signals including TXD, RXD, RTS, CTS, DTR, DSR, DCD and RI. Thanks to the powerful CH384L chipset, the card enables reliable transmissions with flexible baud rates up to 921,600 bps. The integrated FIFO buffer with 256 bytes per direction ensures stable connections are maintained even under high data loads. This makes the card the first choice for professional applications such as machine control, metrology, network management or POS systems. The PCIe x1 interface allows easy integration into existing systems. The card is compatible with both standard and low-profile cases - corresponding brackets are included. The integrated ESD protection up to ±15 kV protects the interfaces from electrostatic discharges. Whether in industry or for demanding hobby projects, this card combines proven technology with modern interface architecture. It is suitable for both current Windows versions and many Linux distributions and offers a wide range of applications for professional and semi-professional users.
