D-Sub PCIE Express serial card for self-service automation machines and kioskes that control serial devices such as touch screens, barcode scanners, receipt printers, label printers, etc. And it also allows compatible devices to power through the serial ports. Suitable for many RS232 serial applications with RS232 drive. This PCIe card provides a selectable 5V or 12V power option that allows output power via pin 9 to configure the card according to the requirements of your RS232 devices. The necessary additional power is directed directly from the PC power supply to the PCI Express card via a disk power plug. The RS232 2-port adapter card features a native PCI Express single chip design that allows you to take full advantage of PCI Express capability and provide improved speed and reliability, while the load on the CPU by up to 48% compared to traditional serial cards that use a bridge chip design Supports x1 slot or higher (X4, x8, x16), maximum data transfer rate RS-232: 250Kbps Only supports Windows 7, 8.x, 10 / Windows Server 2008 R2, 2012, 2016 / Linux 2.6.31 to 4.11.x LTS versions PCI Express card transforms a PCI Express slot into two RS232 (DB9) serial ports. Features: Two RS232 serial ports with data transfer rate of up to 250 Kbps Selectable output voltage of 5V or 12V Output power via pin 9 Complies with PCI Express base specification Revision 2.0. 256 byte depth FIFO per transmitter and receiver. Works as a standard RS232 connector or with 5V or 12V output for devices.
