![]() Bus interface: 3.3v PCI Express Bus signal support.Complete drivers support Windows Vista, XP, 2003, 2000. This PCIEX-400e offers reliable, high speed data transfer for your PCI Express system. The serial port support full modem control signals, to ensure compatibility with a wide range of serial peripherals. Each of the RS-232 serial port supports data rate up to 921.6 Kbps, with automatic data flow control to ensure no data loss. The FIFO buffer is 8 times of the normal 16C550 UART. ![]() Each port supports up to 128 bytes of transmit and receive FIFO buffers. The board is equipped with two 16950 UART. The PCIEX-400e PCI Express 4-Port Serial Board is designed with a DB-44 connector on board and one spider cable fanning out two DB9 male connectors. The new PCI Express system is backwards compatible with your PCI software. There is no need to change your application software. Upgrading your PCI system to the more efficient PCI Express requires a hardware change only. This x1 lane, standard profile PCI Express serial board offers two reliable, high speed ports of RS-232 connectivity, compatible with any PCI Express slot. The board is PCI Express x1 compliant, and works in any PCI Express slot (x1, x4, x8 and x 16 lane PCI Express slots). Compatibility VSCOM Dual Serial Port Card PCI DB-9, 2 port RS-232. Dual serial port card PCI DB-9, 2 port RS-232, high speed serial ports with their 128 byte long FIFO are best for high speed communication, even in heavy loaded systems.
