Model: VXC-142 Model: VXC-142i
VXC-142/VXC-142i
PCI Bus, 2-port RS-422/485 Communication Board
   
 
     
 
 
 
The VXC-142/VXC-142i card provides two independent RS-422/RS-485 serial ports, while the VXC-142i card provides 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 16 bytes hardware FIFO for each port, offers speed up to 115200 bps and supports 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 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, along with the basic communication features.
