VXC-182iAU 2-port Comms Card (1x RS232, 1x Isolated RS422/485)

Description

The VXC-182i serial card provides two communication ports, one is RS-422/485 and the other is RS-232 port. The RS-422/RS-485 serial port can withstand isolation voltage up to 3 kV. It can be configured as either RS-485 for half-duplex or RS-422 for full-duplex communication, offering speeds up to 115200 bps and a long distance communication link.

In harsh industrial environments, the on board ESD protection can protect the computer and equipment from being damaged by high potential voltage.

In addition, 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, making it practical for large file transmission.
