RS232 to CMOS converter with DB9 connector and terminal strip for 3.3 volt CMOS connections.
We designed the CMOS-9-3A converter to provide error free full-duplex data communications for your CMOS applications using a 3-wire RS232 interface. Connections are provided for Tx, Rx, Gnd, and +3.3v sigsnals.
This converter conveniently plugs into the DB9 connector commonly found on the standard IBM-PC.
The CMOS-9-3A can operate for both DTE and DCE configurations with the addition of a NULL modem converter for DCE applications.
