The UT232R is FTDI's premium USB to RS232 evaluation cable which can be used for testing the functionality of the FT232R device and drivers prior to design-in.

The electronics, including the FT232RQ chip, are housed in an attractive white housing. A matching white (2m or 5m) USB cable uses gold plated USB and DB9 connectors. The UT232R evaluation cable uses thumb screws on the DB9 connector to allow for locking the connector to its mating half.

The UT232R cable uses an enhanced RS232 level converter and is capable of communication rates from 300 baud to 1M baud.

The UT232R is fully compatible with Windows 7, RoHS compliant and is CE and FCC approved.
