4-port RS232 communication board

2 February 2011 Computer/Embedded Technology

The VEX-114i communication card from ICP DAS provides four RS232 serial ports and supports PCI Express bus. Each port is equipped with a 128 Byte hardware FIFO, and offers speed up to 115 200 bps. The RS232 serial ports tolerate isolation voltage up to 2,5 kV.

Users can select a specified COM port number manually by DIP switch setting, 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, making it practical for large file transmission.

In harsh industrial environments, the onboard ESD protection component diverts the potentially damaging charge away from sensitive circuits and protects the computer and equipment from damage caused by high potential voltage. The VEX-114i offers optoisolation to protect computers and equipment against damages in harsh environment. The serial communication card is designed for use with intelligent devices like bar code readers, serial printers, intelligent sensors, instrumentation equipment, computers and almost any device with an RS232 port.
