Functional Description　

The VXC-142 card provides two 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. 

The user can select a specified COM port number manually by setting dip switch, or let the driver to choose an available number automatically. The driver provides a maximum of 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. Along with the basic communication feature. 

Advantages 

• Built-in COM-Selector                 

• Self-Tuner Inside

• Up to 128KB software FIFO for each COM port under Windows

• Short Card Design
