Device Driver

The DB9-USB-RS232 module requires USB device drivers, available free from, which are used to make the DB9-USB-RS232 appear as a Virtual COM Port (VCP). This allows existing serial communications software, such as HyperTerminal, to exchange data through the DB9-USB-RS232 to a legacy RS232 peripheral device.

Newer Operating Systems will probably have this driver already installed. If they do not, click on the link at the left, to obtain the FTDI driver for the FT232R chip.
