Introduction
1.1
Functional Description
The USB-COM-Plus adaptors are a family of communication devices. This model, USB2-H-6004, 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 FT4232H Hi-Speed USB-Serial
bridge chip.
Each USB2-H-6004 adapter contains a small internal electronic circuit board which utilises the FTDI
FT4232H, 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.
Figure 1.1 USB-COM-Plus USB2-H-6004
Flexible mounting allows the USB2-H-6004 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 an industry-standard DE-9P connector. The maximum
RS422-level data rate is 10Mbps.
The USB2-H-6004 adapter require USB device drivers, available free from
http://www.easysync.co.uk
or
http://www.easysync-ltd.com,
which are used to make the USB2-H-6004 appear as a Virtual COM Port
(VCP). This allows existing serial communications software, such as HyperTerminal, to exchange data
through the USB2-H-6004 to a legacy RS422 peripheral device.

USB Mini B Client Connector
This connector provides the interface for connection to a USB Host or Hub port. A standard “A to Mini B”
cable is provided, though one of a different length may also be used. The maximum cable length is 5
meters, according to the USB 2.0 specification.
FTDI FT4232H
The FTDI FT4232H provides the USB-to-Serial conversion. Operating system device drivers are required
