FTDI has introduced a series of USB to digital level interface modules, in DB9 form factors to enable USB interconnection in legacy equipment without the need for alteration of the enclosure.
The modules all utilise FTDI’s FT232R USB to serial UART bridge chip, which is capable of supporting data rates of 12 Mbits/s (USB Full Speed). Supplied in a compact 30.8 mm x 19.8 mm x 11.5 mm package, each of the modules uses a standard USB mini-B connector. They have an operational temperature range of -40 °C to +85 °C, permitting them to be specified for heavy duty industrial applications. Drivers for the modules are available to download direct from the FTDI website.
The series comprises the DB9-USB-D3-F (3.3 V output female connector), DB9-USB-D3-M (3.3 V output male connector), DB9-USB-D5-F (5 V output female connector) and DB9-USB-D5-M (5 V output male connector).
