» Functional Description
The VXC-144 card provides 4 independent RS-422/RS-485 serial ports.
Each port can be configured as either RS-485 for half-duplex or RS-422 for full-duplex communication.
It offers speed up to 115.2Kps and long distance communication link.
The user can select a specified COM port number manually by setting dip switches, or let the driver to choose an available number automatically.
The driver provides an up to 128KB software FIFO for each COM port under Windows.
It's practical for large file transmission.
In the harsh industrial environment, the on board surge protection can protect the computer and equipment from being damaged by high potential voltage.
