Quatech Freedom USB Adapter User’s Manual Introduction
Introduction
Note: These products comply
fully with USB Specification
version 1.1 and are fully
supported under Windows
98/ME/XP/2000/NT4.
This Users Manual describes how to setup and install your Quatech
Freedom USB Adapter.
The Quatech SSU-100, DSU-100, QSU-100, ESU-100, and HSU-100,
respectively, provide one, two, four, eight, and sixteen independent
RS-232 serial interfaces to the host PC via the Universal Serial Bus
(USB) port.
The Quatech DSU-200/300, QSU-200/300, ESU-200/300, and HSU200/300, respectively, provide two, four, eight, and sixteen
independent asynchronous serial interfaces via the USB port. Each of
these interfaces can be used as desired for either RS-422 or RS-485
communications.
For convenience, this manual refers to all these products as Freedom
USB unless otherwise noted.
The following table details the port and connection configuration for
all the Freedom USB devices.
Table 1 - Device port and connection options
Device Ports Connection Device Ports Connection
SSU-100 1 RS-232 RS-422
DSU-100 2 RS-232 DSU-200/300 2 RS-422
QSU-100 4 RS-232 QSU-200/300 4 RS-422
ESU-100 8 RS-232 ESU-200/300 8 RS-422
HSU-100 16 RS-232 HSU-200/300 16 RS-422
Note: The 16550 is well suited
for applications involving high
data rates and for heavy
multitasking environments. The
larger FIFO allows each
read/write access to the UART
to move more data, resulting in
fewer interrupts and less
processor time spent servicing
the UART.
Each adapter comes standard with 16550 Universal Asynchronous
Receiver/Transmitters (UARTs) containing 16-byte First In First Out
(FIFO) storage devices. These FIFOs, in conjunction with the USB
micro controller FIFOs, help to relieve the CPU of excessive
interrupts by buffering received and transmitted data. This
configuration allows each channel (either two or four) to obtain data
rates up to 460.8 kbps. The adapters are USB bus-powered; therefore
no external power supply is required.
The Freedom USB products are Plug-and-Play devices and require no
hardware configuration. Your computer's BIOS or operating system
automatically configures the ports when you install the device.

Introduction Quatech Freedom USB Adapter User’s Manual
System requirements
Note: The 16-port units (HSU100/200/300) require two
USB ports. All the other units
use only one USB port.
Quatech’s serial USB adapters require the Windows 98/Me/XP/2000/NT4
operating system and an IBM or IBM-compatible PC with a standard
USB port or an add-in USB host adapter. Contact our sales
department for details on current software offerings. Most device
drivers are available for download from the Quatech World Wide Web
site at http://www.quatech.com/
Features
Quatech offers an IND option, or surge-suppression board upgrade, to
provide improved performance and industrial-grade reliability.
IND option - surge suppression upgrade
The IND option provides essential protection for reliable use in an
industrial environment. Each communication line has a surge
suppressor capable of sustaining up to 40-A, 20-s peak transient
surges, a clamping voltage of 30 V (15.1 V for 200/300 units), and a
peak energy dissipation of 0.1 Joules.
Table 2 differentiates between
the Freedom USB-1/2/300 part
numbers with and without the
IND option.

Installing the Freedom USB
Note: The installation process
takes place in two stages: the
serial adapter board and then
the serial ports.
This section explains how to install the Freedom USB under different
operating systems. Please locate and follow the procedure for your
computer’s operating system.
Windows maintains a registry of all known hardware installed in
your computer in which it keeps track of all of your system resources,
such as I/O locations, IRQ levels, and DMA channels. The Add New
Hardware Wizard utility helps you to add new hardware and updates
Caution! Be sure to allow
the installation process to
finish without interruption.
If you stop the process
before the adapter board(s)
and all of the serial ports
are installed, you will
corrupt the installation.
this registry.
The Freedom USB includes an INF configuration file to allow easy
configuration in the Windows environment. Windows uses the INF
file to determine the system resources required by the Freedom USB,
searches for available resources to fill the boards requirements, and
then updates the hardware registry with an entry that allocates these
resources.
The Freedom USB also includes Windows device drivers that enable
the Freedom USB serial ports to appear to Windows as standard
COM ports.
Installing under Windows XP
Follow these steps to install the Freedom USB under Windows XP.
Step Procedure Description
Step 1 Turn on the power to your computer
system.
This is the system in which the Freedom
USB is to be installed.
Step 2 Plug the wide flat end of the USB cable
into the downstream connector.
Step 3 Plug the square end of the USB cable into
the back of the Freedom USB box.
This is the connector located on the back of
the computer or USB hub.
Windows tells you that it has found new
hardware and launches the Found New
