Windows 7/8/8.1 Installation Guide

Step 1: Insert CD Driver of this product to the CD-ROM. Connect the device to a spare
USB port on your PC.

Step 2: If there is an available Internet connection, Windows 7/8/8.1 will silently connect
to the Windows Update website and install any suitable driver it finds for the device.
If the automatic installation takes place there is no need to continue with the procedure
outlined below. If no suitable driver is automatically found then the following procedure
should be followed.

Press the Windows start button to bring up the start menu and select “Control Panel”.

Step 3: From the Control Panel window select Hardware and Sound

Step 4: At the next screen select Device Manager:

Step 5: In the Device Manager window there will be a device under Other Devices with a
yellow warning symbol to indicate a problem ie no driver installed. The text next to this
device will depend on the device attached. In this example the devices was “USB Serial
Cable” devices.

Step 6: Right click on the other device to bring up a menu as shown below. From the
displayed menu select “Update Driver Software…” This then displays the
option for an automatic search or a manual search.

Step 7: Select the second option to browse manually.

Step 8: click “Browse” and choose the corresponding OS driver in CD. Click “Next” to
continue

Step 9: When the installation has finished a completion screen is displayed.

Step 10: Press Close to close this window and go back to the Device Manager Window.

The Device Manager will still show a device under Other Devices but in addition to this
there is a new entry under Universal Serial Bus Controllers indicated in the screenshot
above as the USB Serial Converter. This indicates the bus layer of the driver is installed.
Installing the Virtual Com Port layer of the driver is almost a repeat of the last few steps.

Step 11: Right click on the other device to bring up a menu as shown below. From the
displayed menu select “Update Driver Software…” This then displays the option for an
automatic search or a manual search.

Step 12: Select the second option to browse manually.

Step 13: click “Browse” and choose the corresponding OS driver in CD. Click “Next”
to continue

Step 14: When the installation has finished a completion screen is displayed.

Step 15: Press Close to close this window and go back to the Device Manager Window.

This time the Device Manager does not have a USB <->Serial Cable entry under Other
Devices but does show entries under Universal Serial Bus Controllers and Ports (COM &
LPT). The above screen shot displays a correct installation. The device is now ready to
use on COM3.

NOTE: Not all devices will install to COM3. The COM port allocation is determined by the
installation wizard on the basis of the next free com port as designated in the PC registry.

Remarks:

After installation if you can see “USB Serial Converter” from the “Device Manager”, but
can’t see “USB Serial Port (COM3)” , please continue next steps.
