PCIe-S114 PCI Express, Serial Communication Board with 4 RS-232 ports

The ICP DAS PCIe-S114 communication card provides four RS-232 serial ports. Each port is equipped with a 256-byte hardware FIFO, and enabling communication speeds up to 921600 bps. The PCIe-S114 card supports automatic COM port allocation by drivers.

The PCIe-S114 serial communication cards is designed for use with intelligent devices like bar code reader, serial printers, intelligent sensors, instrumentation equipment, computers and almost any device with an RS-232 port. Drivers provided for a broad selection of operating systems, including 32/64-bit Windows XP/2003/2008/7/8/10 and Linux Kernel 2.6.31 to 5.16.0.

Hardware FIFO up to 256 bytes:

FIFO stands for “First In, First Out”, an abstraction in ways of organizing and manipulating data relative to time and prioritization. FIFO is used for buffering and flow control while data come from hardware to software. When using hardware FIFO (buffer), a little delay on software or operating system will not lost data at all.

The PCIe-S114 card is equipped with 256-byte hardware FIFO on each port. Large hardware FIFO is useful to prevent data lost when your system works under heavy load, e.g. while running on a multi-task operating system such as Windows and Linux.
