How to Install the Driver
=====================================================================
1) Plug the cable into a USB port.

2) The “Welcome to the Found New Hardware Wizard”  or "Add New Hardware 
	Wizard" (Win98) should appear. If it doesn’t appear, go to step 9.

3) Ensure the product driver CD (included with package) has been inserted 
	in your CD-ROM drive.

4) Select the option, “Install the software automatically (Recommended)”.

5) Press “Next.”

6) Windows should find the “Prolific USB-to-Serial Comm Port” driver. 
	Otherwise you should find the directory under your version of 
	Windows under the "USB to RS232 1.1" directory on the CD-ROM.

7) You will probably see a message indicating that the driver has not 
	passed Windows Logo testing. Press “Continue Anyway.” This warning
	can be safely ignored.

8) Press “Finish” when prompted by Windows to complete the installation.


*** If the “Found New Hardware Wizard” did not appear in step 2 ***
9) Open Device Manager by doing the following:
   a) Click on “Start” and then “Control Panel.”
   b) Switch to Classic View (if in Category View).
   c) Double click on “System.”
   d) Select the Hardware tab.
   e) Press the “Device Manager” button.
10) Under “Ports (COM & LPT),” look for a USB Device entry with a yellow 
	exclamation point '!' by it.
11) Right click on the USB Device and select “Update Driver.”
12) This should bring up the “Welcome to the Hardware Update Wizard.”
13) Ensure the product driver CD (included with package) is inserted in 
	your CD-ROM drive.
14) Select the option,“Install the software automatically (Recommended).”
15) Press “Next.” Continue from step 5 above.




How to Check the Driver Installation
=====================================================================
1) Go to the Device Manager:
	Windows XP/Vista/Win7:  Start -> Control Panel -> System -> Hardware 
		-> Device Manager

2) Click on the plus sign (+) next to "Ports."

3) If the device is installed properly, you will see "Prolific USB-to-Serial 
	Comm Port (COMx)". Note that x is the number of the COM port (typically 
	1-8)  assigned to the adapter.


Port Assignment
=====================================================================
If the driver is installed properly, but the device is not working:
First check to see that your application is set to the correct COM port number. 
To determine the COM port number assigned to the adapter, check the Device Manager 
(see above). Use Addenda's "Adhere" deck control software as a simple utility for 
verifying your cable's operation.

It is also possible that the COM port number assigned is too high. Sometimes a 
device won't  work with the USB-to-Serial adapter even though everything appears 
to have installed correctly because some computers will only scan a limited number 
of COM ports.

For instance, it is possible that a computer has a limitation of scanning the 
first four COM ports. If the adapter is installed on COM5, a device with such a 
limitation will not work until the COM port is reassigned to COM1-COM4.

Windows includes a function that allows you to reassign the COM port. Simply 
follow the instructions below:

Windows XP/2003/Vista/Win7 port reassignment:

1) Follow steps 1 and 2 in "How to Check the Driver Installation."

2) Right click on the "Prolific USB to Serial Port" and click on Properties.

3) Click on the "Port Settings" tab. Click the "Advanced" button.

4) Pull down the scrollbar on the bottom, left side and select COM 1, 2, 3 or 4 
	(NOTE: Choose one that does not say "in use" next to it). Click "OK."

5) Click "OK" again. Notice that the device will show up as being on the same COM 
	port that it was before (i.e., COM5), but will show up on the new port if 
	you close the device manager and open it again.

6) Close the device manager. You may have to run the software that came with your 
	device to make it rescan the COM ports.
