Before you install the device, make sure that your operating system is current (for example, the most recent service pack is installed).

  1. Download the latest drivers from the website at The part number and product ID are on the product packaging.

Note: Windows usually saves the files to the Downloads folder that is associated with your user account (for example, C:\Users\your_name\Downloads).

  1. After the download is complete, right-click the zip folder that you downloaded, click Extract All, and complete the instructions.
  2. Press the Windows key + R, type devmgmt.msc, and press Enter to open the Device Manager.
  3. Right-click PCI Serial Port, which will have a “!” or “?” next to it to indicate a driver issue.
  4. Click Update Driver.
  5. Click Browse my computer for driver software.
  6. Select the Let me pick from a list of device drivers on my computer option.
  7. On the Select your device’s type from the list below screen, click Show All Devices, and click Next.

When you troubleshoot issues with a serial device, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue:

  • Serial cables

  • Serial ports

  • Serial devices

To test your setup components, try the following:

  • Use the serial cable, serial port, and serial device in another setup to see if the problem is with the components or the setup.

  • Use a different serial cable, serial port, and serial device in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup.

When you test your cables, it is recommended that you do the following:

  • Test each cable individually.

  • Use short cables when you are testing.

When you test the serial ports and serial device, it is recommended that you do the following:

Note: Some serial devices work only if the COM port number is between a certain range. For example, COM1 to COM4.

To check whether or not an RS-232 serial port is working, perform an RS-232 loopback test by doing the following:

  1. If your serial port is not female, convert it by taking a female/female cable or gender changer and plugging it into the serial port.
  2. Take a metal paperclip or wire and cross pins 2 and 3. If you look closely at the female end, the pins should be numbered.
  3. Open a telnet session on the COM port number of the device that you are testing. To find out the COM port number, refer to the following FAQ:

Note: To open a telnet session on the COM port, you need a telnet client like PuTTY or Hyper Terminal. Windows XP comes with Hyper Terminal.

  1. When the session is open, anything you type into it you should see. The loopback test fails when you cannot see what you are typing.

If the loopback test fails, make sure that the serial cable or gender changer that you are using works and that the adapter is in the correct port. 

You can check multiple ports at the same time by opening multiple sessions, putting the loopback adapter on one port, and trying to type into each session.  When you can see what you are typing, you know that the COM port is working and you can see which port number the physical serial port is. Close the window for the port that you just tested to speed up the testing of the remaining serial ports.
