ICP DAS New Product: VEX-114
PCI Express, 4-Port RS-232 Communication Board
 
 
Introduction:
The VEX-114 communication card provides 4 RS-232 serial ports and supports PCI Express bus. Each port is equipped with a 128-byte hardware FIFO, and offers speed up to 115200 bps.

Users can select a specified COM port number manually by setting DIP switch, or let the driver choose an available number automatically. The driver provides a maximum of 128 KB software FIFO for each COM port under Windows. It's practical for large file transmission.

The serial communication card 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.
 
Hardware FIFO up to 128 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.
VXC/VEX Cards are equipped with 16- or 128-byte hardware FIFO for each port. Large hardware FIFO is useful to prevent data lost when your system works on heavy loading, e.g. while running on a multi-task operating system, such as Windows, Linux¡K etc.
