The USB2-H-6002 provides a simple method of adapting legacy serial devices with RS422 interfaces to a modern USB 2.0 Hi-Speed port. This is accomplished by incorporating the industry standard FTDI FT2232H Hi-Speed USB-Serial bridge chip.
Each USB2-H-6002 adapter contains a small internal electronic circuit board which utilises the FTDI FT2232H, 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-H-6002 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-Mini B client connector for connection to an upstream host or hub port. RS422-level signals are available on each of the 2 port industry-standard DE-9P connector. The maximum RS422-level data rate is 10Mbps.
The USB2-H-6002 adapter require USB device drivers, available free from http://www.easysync-ltd.com, which are used to make the USB2-H-6002 appear as a Virtual COM Port (VCP). This allows existing serial communications software, such as HyperTerminal, to exchange data through the USB2-H-6002 to a legacy RS422 peripheral device.
