Future Technology Devices has announced the availability of the DB9-USB-RS232 range of modules for systems equipped with legacy DB9-based RS232 connectors.

The range is designed to replace a DB9-based RS232 connector on an existing board design with a USB 2.0 connector interface.

The modules feature a standard USB ‘mini-B’ type connector in a module that fits the PCB footprint of a standard nine-pin DB9 connector.

The modules are designed to provide a fast and simple method of replacing a DB9 RS232 interface with USB 2.0 connectivity, without the need to change an existing PCB design.

Two DB9-USB-RS232 modules are available to replace male or female DB9 connector versions.

The modules are targeted at systems equipped with legacy DB9-based RS232 connectors, which often face connection issues to modern PCs, laptops and other equipment.

They provide a mechanism to extend the lifecycle of these systems, while providing enhanced capability through the introduction of USB 2.0 connectivity available via the DB9-USB-RS232 modules.

The modules contain all the electronics needed to carry out the conversion between RS232 and USB.

The modules utilise the FTDI FT232R, USB 2.0 to serial UART converter IC, which handles the USB protocol conversion.

The FT232R device converts from USB to a serial UART interface, which is then level-shifted into RS232 signal levels, within the DB9-USB-RS232 module.

Power to the module is supplied by the USB 2.0 connection.

The modules support a maximum transfer rate of 1MBits/sec on the RS232 interface.

The DB9-USB-RS232 modules are supplied complete with FTDI’s royalty-free drivers, which enable a device to be integrated as an additional (virtual) COM port into an existing software application, therefore offering quick and easy installation without the need for custom driver development or user software redesign.

The range of drivers includes Microsoft WHQL certified drivers for Windows-based operating systems and drivers for Linux and Mac OS operating systems.

All drivers are freely available for download from the FTDI website.
