Introduction
1.1
Functional Description
The USB-COM-Plus adaptors are a family of communication devices. This model, USB2-F-1001, provides
a simple method of adapting legacy serial devices with RS232 interfaces to modern USB ports. This is
accomplished by incorporating the industry standard FTDI FT232R USB-Serial bridge chip.
Each USB2-F-1001 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 RS232 level shifters and TXD/RXD LEDs to provide a
visual indication of data traffic through the adapter.
Figure 1.1 USB-COM-Plus USB2-F-1001
Flexible mounting allows the USB2-F-1001 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 device connector for connection to an upstream host or hub
port. RS232-level signals, including modem handshake signals, are available on an industry-standard
DE-9P connector. The maximum RS232-level data rate is 1Mbps.
The USB2-F-1001 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-F-1001 appear as a Virtual COM Port
(VCP). This allows existing serial communications software, such as HyperTerminal, to exchange data
through the USB2-F-1001 to a legacy RS232 peripheral device.
In addition to the device drivers, a configuration utility is available to change the definition of Pin 9 of the
D-sub connector. The USB-COM-Plus Configuration Utility is available free from
http://www.easysync.co.uk or http://www.easysync-ltd.com,

USB B Client Connector
This connector provides the interface for connection to a USB Host or Hub port. A standard “A to 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 FT232R
The FTDI FT232R provides the USB-to-Serial conversion. Operating system device drivers are required in
order to work with the FT232R to provide the Virtual COM Port serial functionality.
RS232 Level Shifter
The RS232 level shifter converts the signals provided by the FT232R into the voltage levels required by
RS232 devices.
DE-9P Connector (Male)
The DE-9P connector is configured in an industry standard (TIA/EIA-574) pin-out to provide connection
to RS232 peripherals through standard cables. See section 3.1.2
