PCI Express 4-Port Industrial Serial I/O Cards
The PCIe-400i and PCIe-400i-SI PCI Express 4-port industrial serial I/O cards are plug & play
high-speed serial I/O expansion cards for the PCI Express bus. Connecting to a PCI Express
bus on your computer, the PCI Express 4-port industrial serial I/O card instantly adds four
RS-422/485 serial I/O communication ports to your system. The PCI Express 4-port industrial
serial I/O cards are designed to utilize the Exar XR17V354 PCI Express to UART chip. The
PCIe-400i & PCIe-400i-SI support high-speed data rate up to 921.6 Kbps. Each serial port is
fully compatible with 16C550 UART, with enhanced feature of 256 bytes TX and RX FIFO
buffer for higher performance.
The PCI Express 4-port serial I/O card is an advanced and high efficient solution for serial
data communication and industrial automation applications.
