Serial Data Converter
CONV232/485 and CONV232/422 convert between RS-232 communications (as used by the COM1 and COM2 ports standard on most motherboards) and balanced-mode, long distance RS-485 and RS-422 communications. CONV232/485 was designed for use with our REMOTE ACCES line when there is no RS-485 port on your PC, but may also be used in other, similar applications.
Balanced-mode, long-distance RS-485 and RS-422 communication with no internal installation
External power not needed for small networks
Nothing to configure; automatically detects baud rate and format
