Product ID: MPEX2S1P552
The MPEX2S1P552 2S1P Mini PCI Express Serial/Parallel Combo Card turns a mini-PCIe slot into two RS232 (DB9) serial ports, and one IEEE 1284 parallel port - a cost-saving solution for adding serial and parallel support to embedded systems that lack built-in serial/parallel functionality.
The 16650 UART adapter card features a native PCI Express single chip design, which enables you to take advantage of full PCI Express capability, by providing improved speed and reliability while reducing the load applied to the CPU by as much as 48% over conventional "bridge chip" serial cards .

To install the driver:
Note: Windows will typically save the files to the Downloads folder that is associated with your user account (for example, C:\Users\your_name\Downloads).
Note: If the Run as Administrator option is not available, you might be attempting to run the installer from within the zipped file. Extract the files using the instructions in Step 2.

Older applications that use serial communication often use legacy hardware addresses that do not work with PCI, PCIe, or USB to Serial products. We recommend contacting the software provider/support team to check if this is the case.
To check whether or not an RS-232 serial port is working, perform an RS-232 loopback test by doing the following:
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.
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.

When you troubleshoot issues with a serial or parallel hybrid 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 or parallel cables
Serial or parallel ports
Serial or parallel devices
To test your setup components, try the following:
Use the serial or parallel cable, serial or parallel port, and serial or parallel device in another setup to see if the problem is with the components or the setup.
Use a different serial or parallel cable, serial or parallel port, and serial or parallel 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 or parallel ports and serial or parallel device, it is recommended that you do the following:
Press the Windows key + R, type devmgmt.msc, and press Enter to open Device Manager. Check to see if your device is listed under Ports (COM & LPT).
Make sure that the COM or LPT port number is the correct number for the serial or parallel device and that the software being used to connect the computer to the serial or parallel device uses the correct COM or LPT port number.
If you do not see the COM or LPT port number in Device Manager see this FAQ for PCI/PCIe expansion cards: https://www.startech.com/support/faqs/technical-support?topic=expansion-cards#pci-pcie-cannot-boot-os-or-detect-windows
or this FAQ for USB devices: https://www.startech.com/support/faqs/technical-support?topic=expansion-cards#usb-cannot-detect-windows
If the device is listed with an error, follow the instructions on the website to reinstall the drivers.
Note: Some serial devices work only if the COM or LPT port number is between a certain range. For example, COM1 to COM4 for serial and LPT1 and LPT2 for parallel.
Perform a serial loopback test. See this FAQ on how to perform a RS-232 serial loopback test: http://www.startech.com/faq/serial_loopback_test_rs232_windows
Note: There is not an equivalent loopback test that can be performed for parallel devices.
To confirm that Windows detects your expansion card, complete the following:
Your expansion card is listed according to the name of the chipset. To determine the name of the chipset of your expansion card, navigate to www.StarTech.com and look on the Technical Specifications tab for your product.
