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

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).

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  
Figure 11 - DB9 connector pinout.  
DCE device provides a communication channel between  
two DTE-type devices.  
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.

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.
