The VXC-144U card provides 4 non-isolated RS-422/RS-485 serial ports and 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 equips 128 bytes hardware FIFO for each port, offers speed up to 115200 bps and long distance communication link.
Users can select a specified COM port number manually by setting dipswitch, or let the driver to 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 the harsh industrial environment, the on board ESD protection can protect the computer and equipment from being damaged by high potential voltage.
