SKU USB2-F-6001

< USB2-F-6001 earliest delivery date in April 2021>

The USB2-F-6001 provides a simple method of adapting RS422 serial devices to a USB port.  This is accomplished by incorporating the industry standard FTDI FT232R USB to Serial bridge chip.

Each USB2-F-6001 adapter contains a small internal electronic circuit board which utilises the FTDI FT232R, mounted inside a rugged plastic enclosure capable of withstanding industrial temperature ranges. The integrated electronics also include RS422 level shifters and TXD/RXD LEDs to provide a visual indication of data traffic through the adapter.

Flexible mounting allows the USB2-F-6001 to be used in a variety of applications, from a portable adapter to accompany a laptop to permanent installations in industrial, commercial and retail locations.

The enclosure incorporates a standard USB-B client connector for connection to an upstream host or hub port.  RS422-level signals, are available on an industry-standard DE-9P (DB9) connector.  The maximum RS422-level data rate is 3 Mbps.  

The USB2-F-6001 adapter require USB device drivers, available free from, which are used to make the USB2-F-6001 appear as a Virtual COM Port (VCP). This allows existing serial communications software, such as HyperTerminal, to exchange data through the USB2-F-6001 to a legacy RS422 peripheral device.
