The VXC-144iU card provides 4-isolated RS-422/RS-485 serial ports which withstand isolation voltage up to 3 kV.
Each port can be configured as either RS-485 for half-duplex or RS-422 for full-duplex communication. It is equipped with 128 bytes hardware FIFO for each port, offering speeds up to 115200 bps and suitable for long distance communication links.
Users can select a specified COM port number manually by setting dipswitch, or bu letting 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 on board ESD protection can protect the computer and equipment from being damaged by high potential voltage.
