DB9 USB to Digital Modules

DB9 USB to Digital Modules

FTDI has added a series of USB to digital level interface modules, in DB9 form factors, to its product portfolio. 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) enable implementation of USB interconnection into legacy equipment without the need for alteration of the enclosure or any noticeable increase in the overall bill of materials.

These modules utilize FTDI's FT232R USB to serial UART bridge chip, which is capable of supporting data rates of 12 Mbits/s (USB Full Speed). They allow for the quick and easy upgrading of pieces of hardware to today's most widely used serial interface standard in a highly convenient and cost effective manner.

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.
