The VScom 200I uPCI is designed for RS232, RS422/485 industrial communication. It supports 2 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.
In addition, hardware flow control and built-in termination resistors guarantee data integrity.
All of these features make VScom 200I PCI suitable for harsh industrial applications.
