Introduction
This manual describes how to set up and install your USB-to-Serial Adapter.
U209-004 and U209-008 provide four or eight independent RS-232 serial interfaces to the host PC via
the Universal Serial Bus (USB) port.
Each adapter uses high-speed UARTs and deep FIFOs, allowing each channel to obtain data rates up to
921.6 kbps. The adapters are powered over their USB connection (bus-powered), eliminating the need
for an external power supply. The adapters are Plug-and-Play devices and require no hardware
configuration.
Note: These products comply fully with USB Specification version 2.0. They will also operate over slower USB 1.1
connections at a slightly reduced performance level.
System requirements
USB-to-Serial adapters are supported under the Windows 2000/XP (and later) and Linux operating
systems. One USB port is required to connect the adapter to your computer. You can use either a built-in
USB port or an add-in USB host adapter. We recommend the use of a USB 2.0 port for best performance.
Installing the USB-to-Serial Adapter
Caution!
Be sure to allow the installation process to finish without interruption
This section explains how to install the USB-to-Serial adapter under different operating systems. Please
locate and follow the procedure for your computer's operating system.
The USB-to-Serial adapter includes Windows device drivers that enable the serial ports to appear to
Windows as standard COM ports.
Installing under Windows XP
Follow these steps to install the adapter under Windows XP.
1. Turn the power to your computer ON. This
is the system to which the device is to be
connected.
2. Plug the wide flat end of the USB cable into
the downstream connector. This is the
connector located on the back of the computer
or USB hub.
3. Plug the square end of the USB cable into
the USB-to-Serial adapter. Windows tells
you that it has found new hardware and
launches the Found New Hardware Wizard
(figure 1).
Figure 1 - The Found New Hardware Wizard launches
automatically when you first plug in the USB-to-Serial
adapter.

Making external connections
RS-232 Serial Connections
RS-232 devices are classified by their function as
either Data Terminal Equipment (DTE) or Data
Communication Equipment (DCE).
Note: A DTE device is the communication source. A
DCE device provides a communication channel between
two DTE-type devices.
Figure 11 - DB9 connector pinout.
USB-to-Serial adapters are DTE devices that
connect to peripheral equipment through a male
DB-9 connector. The following table lists the serial
port connector definitions.

Figure 12 - Use of DTEs and DCEs in a
communication link.
Cabling requirements for RS-232C devices
DTE- and DCE-type devices have complementary
pinouts that allow terminals and modems to
connect directly using a one-to-one cable as shown
in Figure 13. Two DTE-type devices can be
connected by a null modem cable. A typical null
modem cable is also shown in the figure.
Figure 13 - illustrates the RS232 pinouts for typical
DTE- to-DCE and DTE-to-DTE cables with 9-pin
connectors.
Note: In many applications, DCEs are unnecessary.
This allows you to use a null modem cable (modem
eliminator cable) to directly connect two DTE type
devices.

first serial port. Note: Leave all settings at default.
5. With the session open, type any text. If the text you type is echoed on the screen, the port is
functioning properly.
6. Close the session.
7. Repeat steps 3 through 6 for each serial port. If the text you type is echoed on the screen, the port
is functioning properly.
