The VScom 400I uPCI is designed for RS232, RS422/485 industrial communication. It supports 4 independent RS232, RS422 or RS485 ports. Each port can be configured separate. Available modes : RS232, RS422 fullduplex RS485 full duplex (4 wire) RS485 half duplex (2 wire) with and without echo.
In RS485 modes applications enable transmission by simply sending data. This is done by ART (Automatic Receive Transmit Control) intelligence. The Transmitter is disabled exactly with the end of the last character sent. No modification is necessary in programs. The common control by RTS is possible for compatibility. In addition, hardware flow control and built-in termination resistors guarantee data integrity. Surge protection is also available for RS232 Signals to deliver high reliability. All of these features make VScom 400I uPCI suitable for harsh industrial applications.
