The RS-422/485 serial ports of VEX-142i tolerate isolation voltage up to 2.5 kV. 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.

In harsh industrial environments, the on board ESD protection component diverts the potentially damaging charge away from sensitive circuit and protects the computer and equipment from damage caused by high potential voltage.

VEX-142i offers photo isolation to protect your computer and equipment against damages in harsh environment. It can help cutting down on-ground loops, common-mode voltages and blocking voltage spikes, provide electrical isolation, and offer significant protection from serious over-voltage conditions in one circuit affecting the other.

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-422/485 port.
