The VXC-182iU serial card provides two communication ports, one is RS-422/485 and the other is RS-232 port. It can be configured as either RS-485 for half-duplex or RS-422 for full-duplex communication, supports for speed up to 115200 bps and is capable of transmitting information over a long distance communication link.
Users can specify a 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 being damaged by high potential voltage.
The serial communication card are 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.
