Q1. Is there a diagnostic program I can use to determine if my RS-232 serial PCI board is working?

A. There are several ways to go about testing the product. The easiest way for Windows users is to connect a Loopback on the Port and use HyperTerminal to test it. HyperTerminal is included with Microsoft operating systems. If you don't see it listed in Program Manager, you may need to install it from the Windows CD. OS/2 users may use the HyperAccess Lite application in the OS/2 BonusPak to do the same. RS-232 Loopback Instructions

Q2. Why can't I get my serial board to perform at 921.6 kbps?

A. Data rates (or baud rates) are highly system dependent. It is impossible for Quatech to know exactly how one of our products will perform in your specific system. Some major factors that affect baud rate are cabling, OS, and FIFOs. For more information about maximum data rates, see the Quatech "Serial Data Rate Information Sheet"

Q3. Under which OS is my RS-232 Serial PCI Board is supported?

A. View the latest OS support matrix for RS-232 Serial PCI Board.

Q4. How do I install my RS-232 PCI Board under Windows 2000/XP?

A.

1. Install your hardware according to the instructions in your user's manual. Boot your machine.
2. The "Welcome to the Found New Hardware Wizard" window will open.
3. Click "Next" to continue.
4. Follow the on-screen instructions. When prompted, point Windows to the location in which the Quatech drivers are stored-typically on the Quatech COM CD, or the folder on your hard drive to which you downloaded the drivers.

Q5. All of Quatech's Serial PCI boards have a Microsoft Windows XP registered driver. In some cases, changes and updates are available that have not yet been registered. What does it mean to have an unregistered Windows XP driver? Why do I get a warning screen when I install some drivers from the Quatech COM CD?

A. Microsoft has implemented a new driver signing program. This program verifies that the driver will not cause problems on the system. Although driver signing isn't a complete indication that a driver is safe or bug-free, it's certainly reasonable to assume that signed drivers are generally safer for overall system health than unsigned drivers. In addition, driver signing ensures against a Trojan horse or virus application being introduced into a driver, or having the driver replaced with other code.

However, just because a driver is unsigned DOES NOT mean that it will not function properly in your system. An "unregistered" driver is one that has not been officially tested and certified by Microsoft. Unlike previous versions of Windows, Windows XP warns users every time they try to install a driver that Microsoft has not certified. Quatech thoroughly tests all drivers before releasing them to our customers. The Microsoft XP warning has nothing to do with the quality of our driver or its ability to function properly in your system.

XP driver development is an ongoing process. We are in the process of submitting all Quatech Windows XP drivers for review by Microsoft, and we fully expect to receive certification for most products in the coming months. However, every time we update a driver it must be re-certified. Until this certification process is complete, the updated driver will remain unsigned. Because we want to provide the best possible service for our customers, we release our XP drivers prior to receiving Microsoft certification--this gets it into your hands faster! However, we will always continue to make the most recent signed driver available even if there are more recent unsigned updates.

When you see this warning during an installation of a Quatech's Windows XP driver, simply tell Windows that you want to install the driver anyway, and continue with the standard installation process.

Q6. How do I disable the Windows XP Driver Signing check?

A. To disable Windows XP driver signing warnings, follow the steps below:

1. Double click on the System icon in Control Panel.
2. Left click on the Hardware tab.
3. Left click on the Driver Signing button. (click here for a screen cap of the Driver Signing Options Window
4. Choose the Ignore option. Click on O.K. and then Apply and O.K.
5. Windows will not warn anymore about driver signing.

Q7. How do I install my PCI Serial Board under Windows 95/98/Me?

A. An "INF" configuration file is included with your Quatech Serial board to allow easy configuration in the Windows 95/98/Me environment. Also, a custom Windows 95/98/Me serial device driver is included with the board to support the use of the 16750 UART's 64 byte FIFO. Windows 95/98/Me uses the "INF" file to determine the system resources required by your board, searches for available resources to fill the boards requirements, and then updates the hardware registry with an entry that allocates these resources.

The following instructions provide step-by-step instructions on installing a Quatech serial PCI board in Windows 95/98/me using the "New Hardware Found" wizard.

1. After booting the computer with a newly-installed PCI serial board, the "New Hardware Found" dialog box will appear. If you have never installed a Quatech PCI communications adapter before, the dialog box may simply indicate that it has found a "PCI Card."
2. Select the radio button for "Driver from disk provided by hardware manufacturer." Click the "OK" button to continue.
3. An "Install From Disk" dialog box should pop up. Insert the Quatech COM CD with the Quatech INF files on it, select the correct drive letter, and click the "OK" button. Windows 95/98/Me automatically browses the root directory for an .INF file that defines configurations for Multi-function Adapters. If no INF files are found, click the "Browse" button and navigate to the "\Serial Port Adapters\Drivers\Windows 95, 98, Me for PCI" folder on the Quatech COM CD. You are not required to select the file name. After finding the directory containing the INF files, Windows 95/98/Me will choose the correct file.
4. The "New Hardware Found" dialog box will appear again, this time for an "Unknown Device."
5. Again select the radio button for "Driver from disk provided by hardware manufacturer." Click the "OK" button to continue.
6. Another "Install From Disk" dialog box will pop up. The path should already be pointing to the Quatech COM CD. Click the "OK" button to continue.
7. You should now see the "Copying Files" dialog box as Windows 95/98/Me copies the driver files from the CD.
8. The installation utility will ask for your Windows 95/98/Me system CD. Serial communication ports require two drivers supplied by Microsoft to function: SERIAL.VXD and SERIALUI.DLL. Insert the Windows CD and click "OK"
   
   NOTE: You may be able to skip this step if you are certain that your system has the latest version of these files installed. If you do not have your Windows 95/98/Me system CDs immediately available, click "OK" anyway. A dialog box appears with an option to Skip the files. Click the Skip button and the files will not be installed. This is all right if the latest versions of these drivers are currently in the \WINDOWS\SYSTEM directory.
   
   
9. The "New Hardware Found" dialog will repeat as each serial port is registered with Windows 95/98/Me
10. Installation is complete.

Q8. My PCI serial board installs as COM 5&6 under Windows 95/98/Me, but my application can only use com port 1-4. How can I configure my card to use com ports 1-4.

A. See our COM Port Enumeration Tip Sheet for answers to common questions about installation.

Q9. How do I uninstall my PCI serial board under Windows 95/98/Me/2000/XP?

A. The following procedures should be used to uninstall a Quatech PCI board- where noted specific instructions will be given for any platform dependent procedures. The uninstall procedure should be used when you want to completely delete a Quatech card from your system--either because you will no longer be using the card, or if you want to "start from scratch" with a newer version of the driver.

Step 1: Remove the product from Device Manager

1. Open Device Manager and find the Quatech product.
2. Highlight the product and click on the Remove button (Win9x)
   or right click on it and chose uninstall from the menu (Win2000/XP).

   1. Enable Device Manager to view hidden devices: Start/control panel/System/Advanced/Environment Variables
   2. Under System Variables, click New.
   3. For variable name, enter "DEVMGR_SHOW_NONPRESENT_DEVICES".
   4. For value, enter 1.
   5. "OK" all the way back out.
   6. Close and reopen Device Manager. Select "View/Show Hidden Devices".
   7. As a test, there should be a new category called "Non-Plug and Play Devices." (Ignore it)
   8. Look for any Quatech related entries. Delete them.

Step 2: Delete .inf and .pnf files

1. In Windows Explorer, go to the Tools menu and select Folder Options...
2. On the View tab enable Show Hidden files and folders.
3. Uncheck Hide extensions for known file types.
4. Uncheck Hide protected operating system files (Recommended).
5. Click on Apply and O.K.
6. Find the inf folder on the left hand side of Windows Explorer. It will be located at c:\windows\inf or c:\winnt\inf (Win2k).
7. Right click on the inf folder and select Search or Find...
8. Fill in the following information for the search Results Window.
   All or part of file name: *.inf
   A word or phrase in the file: quatech
   Look in: inf
9. Click the search button.
10. The search results will list a file called msports.inf. Do nothing with this file.
11. The files of interest are anything named oem?.inf. ? meaning a number (i.e. oem3.inf). Delete the oem?.inf file that is returned for you from the c:\windows\inf folder.
12. You will also see a oem?.pnf (i.e. oem3.pnf) file. This "sister" file must also be deleted.

Q10. How do I install my RS-232 PCI Board under Windows NT?

A. Quatech provides a Device Manager for Windows NT that is used to install serial PCI boards. The Quatech Device Manager utility includes a simple add hardware wizard to guide you through the installation. The Device Manager is located on the Quatech COM CD.

Q11. Where can I find help with using my RS-232 Serial PCI Board under OS/2?

A. Though OS/2 is becoming increasingly less popular, Quatech knows that there are many dedicated users out there, and we are committed to continued support of OS/2. See our OS/2 tip sheet for answers to common questions about installation, un-installation, configuration, and troubleshooting.

Q12. Do I need local administrator rights to install a Quatech serial device?

A. Yes. When installing most kinds of hardware, you must have local admin rights or equivalent on the PC. If your computer is part of a Domain or participates in a networked environment, please contact your local LAN Administrator for assistance.

Q13. I have an ESC-100M and I want to convert it to D-25. What color wire corresponds to each PIN number?

A. When the RJ-11 connector is converted to D-25, the adapter cables must be assembled with respect to either a DTE or DCE configuration. The standard serial port connections, along with a color code for the signal wires, are provided below:

Q14. My Quatech PCI card locks up my Dell Optiplex, what can I do?

A. This is a problem with older version of BIOS on the Dell Optiplex. Please obtain the most current bios update for your model directly from Dell.

Q15. When installing a product, I get an error message stating "The System Cannot Find the File Specified." How can I fix this?

A. Windows 2000/XP has a bug that it cannot properly detect new hardware by *.inf files, if the RunOnce registry key is missing.
This key is often used by installers to execute post-reboot programs, but sometimes they accidentally delete this key.

Go to Start » Run and enter "regedit"
Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion
With CurrentVersion Highlighted, go to the Edit menu and select New » Key
Name the key RunOnce  - Leave everything else about the key alone.
The RunOnce key should now exist underneath the CurrentVersion key.

Reboot your PC.
Once the key exists, Windows 2000/XP stops redetecting the Hardware

Q16. I purchased a QSC-100 with a DB-9 to DB-25 adapter to connect to my RS-232 25 pin serial device, but I do not have the pinout for the DB-25. Where can I find this pinout?

A. The pinout for the DB-9 to DB-25 adapter is as followed:

Q17. I upgraded my PCI Serial Board to a Window Vista PC, but my existing driver will not install my PC card. What could be the problem?

A. All of Quatech's Serial PCI Boards are supported under Windows Vista with driver version 1.90 or greater. If your driver is not at 1.90 or later, you will need to download the current driver from our web site.

Q18. My jumpers on my new board do not match the jumpers on my old board. How do I know how to configure my new card so the settings are the same as my old card?

A. All of the Universal PCI Serial Cards have the ability to be configured through software selections. Hardware jumper settings are no longer necessary to configure the PCI card. Please see your User's Manual for further details on software selections.

Q19. After updating the driver on my serial card, the device manager shows a yellow exclamation point with an error code 10 (Device can not start). What happened?

A. All of our serial devices have two separate listings in Device Manager after installation. The parent device, which will be your device name, will be listed under Multiport Serial Adapters. The second listing is for the COM ports themselves, which will be found under "Ports" (COM and LPT).

When updating a driver for a Quatech device, you will need to be sure that you run the update for both the board and the ports. If the driver for the board and ports do not match, an error code 10 will appear. To check your driver version, please right click on the board/ports and go to "Properties." From there, you will click on the drivers tab.

Q20. My UniversalPCI device will not install with the drivers provided. My board is identified as a PCI device.

A. The two common reasons this happens are:

1. The card programming has somehow become corrupted
2. The PCI slot you are plugged in to is having issues.

If at all possible, please try to install on another PC. That would determine if the issue is with the card or PC. If it is the card, please contact Quatech at 800.553.1170.

Q21. Why can't I change my port settings in Windows Device Manager?

A. The application used with the device manager interface changed from a drop down menu to a toggle. Please refer to the screen shot below:

Q22. My new revised DSC-100 does not look like the DSC-100 I purchased in the past. What has changed?
