Web Cable Installation & Troubleshooting


Software on supplied disks

If you did not receiver version 4.31 software with your Web Cable, please download this version from the Software Download area of this web site.

Please note:  The software included with your scan converter is OPTIONAL.  It is not needed to make the scan converter work properly (with the exception of configuring for PAL).  This software is a screen control utility only.  It is not a driver. 

If you have not installed the software and you are having trouble making your scan converter work properly, installing the software will not help.  It is recommended that you get the scan converter working before you install the software - in most cases it is not needed. (See also Scan converter FAQ's    -- Do I have to install the software?)


There are three main parts to setting up your scan converter - physical installation, system setup and software installation - you can jump to the specific section by clicking on the 'bookmark' below.

Hardware Installation   


            See the attached list of connector types if you are unsure.


NOTE!!! An RF modulator is not the same device as the common video game connector box!  Be sure that you are using a true RF modulator when attempting this kind of connection.  Most VCRs have a built in RF Modulator, this is the F connector labeled Out, To TV or RF Out.  See the VCRs manual for details on using it to show the output of the scan converter.

Image showing the connector that go to your TV.  You must have at least one matching connector on your TV or VCR to use the Web Cable. 

Normally you will use only one of these.   It is recommended that you use the S-Video connector if it is available on your TV or VCR.

Image showing the VGA and power adapter connectors.  Connect To VGA port connector to the VGA port on your computer VGA card or the rear of your laptop.  Connect the To Monitor Cable connector to the connector at the end of your monitor cable.  If you are using a laptop computer you will likely not use this connector.  You do not need a monitor to use the scan converter.

Image showing the AT (or ISA) keyboard power adapter.  You will use this only if you have an older computer with the larger AT keyboard connector.

Connect the keyboard to the adapter, your Web Cable PS/2 connector to the side leg, and then plug the adapter into the AT keyboard port on your computer.

2)   VERIFY INSTALLATION              


  1. HOTKEYS - The majority of laptop computers use a HOTKEY combination to switch the computer among it's supported video display modes. An "Fn" key is typical - used in combination with a function key ( F1-F10). (see also Laptop VGA mode switching  ).
  2. SOFTWARE- Some Laptops us a piece of software to change the modes. This is usually accompanied by a re-booting of the machine. There may be a tab in the Display Properties or in the Start/Programs menu for your laptop.  Some laptops require making this setting in the BIOS Setup
  3. AUTO-DETECT - Some laptops try to auto-detect whether there is a monitor attached to the external VGA port, and will switch to it if there is when you boot up the laptop. 

**AITech's earlier scan converters do not appear as a monitor to some laptops - which may require booting with a computer monitor attached, then switching to the scan converter. **


Your TV will have one or more of the following connectors on its rear panel for inputting signals.

"F" Connector - This is a Threaded connector used for the antenna, and Cable TV connectors. This is a standard connector for TV's, and VCR's. The "F" connector is for RF (Radio Frequency or broadcast) signals ONLYRF signals combine the VIDEO and AUDIO information into one signal on a high frequency RF carrier. The RCA connector is the industry standard for audio and video connectors on consumer electronics devices. S-video (separated video) is a standard that separates the (composite or combined) video signal into its component parts.

System Setup      


Basic Settings                                      

The scan converter requires four basic settings in Windows. These setting will be made differently depending on whether you use Windows 3.x or Win95/98. For Windows 3.x follow the instructions in the User's Manual. In Windows 95/98 you must make the three (shown settings shown below):





With the release of Windows 98, there are now some 4 or 5 different version and ways to make adjustments to the operating system. There were at least 3 releases of Win95 and now with Win98 Beta and the final release there were differences in making some settings.

Some of these differences are addressed in the setup procedures shown below. If you do not see the exact screen captures for your version of the operating system you should be able to get the general idea of what you need to do with the information that is available here.

All releases have the same main dialog boxes - some of the buttons to get to them may be different and you may see some Wizard boxes added in Win98 there were not there in Win95. Again, the dialog boxes where you make the important changes are substantially the same.

Right click a blank area on your desk top - you should see the menu shown below.

Refresh Rate                               

You should have four or more tabs showing (figure 8). Click the Settings tab. The setting for the Color Palette is on the lower left, and next to it on the right is the setting for Desktop Area. Set these as directed above and shown in figure 8. You may have a tab that says Scan Rate or Refresh Rate or one with a manufacturer's name on it. Check this tab to see if there is a setting for the scan rate. Set this for 60 Hz. In Windows 98 click on the Advanced button (figure 8) to see the dialog box below. Click the down arrow in the Refresh Rate box. Select 60 Hz. If there is no setting for 60 Hz, select Adapter default.

To change your monitor type, click on the Monitor tab. Note the current monitor setting is shown next to the icon at the top left of the card (figure 10) and in the Wizard box in figure 11.

    Click Next to continue…

    DO NOT CLICK THE "Activate True-TV Size Driver Now" selection.

    Note: this option has been removed in versions 4.31 and above).

    You can determine later if this option is needed. Clicking the Activate Now option can cause an incomplete installation if your video driver is not supported by the True-TV driver.

  6. Continue with the installation of the software until it is complete.


Running the Software      

Update the Driver                                         

Updating the display driver changes your previous setting of 640x480 to 600x440. This shrinks the image (noticeable on monitor) to better fit the image on your TV screen. When you want to return to normal computer use when done with the scan converter do a Restore Driver ( described below).

  1. Click Start - Programs - AITech Scan Converter - Update Display Driver - Click OK

    Figure 17 - Update Driver dialog

  2. Click OK.

    running2.jpg (19767 bytes)

    Figure 18 - Restart dialog

  3. Note the message says you must restart to make these changes take effect. Click Yes to update the driver.
  4. If your system has a video driver that is not supported by the True-TV Size driver you will see the warning box below.


Figure 19 - Update warning - v 4.31 does not ask you to change the driver.


At this stage you have two options - leave things as they are and work around any size issue you may have; or change to the Standard VGA driver so you can use the True-TV Size driver. Please see the document on our Web site dealing with sizing issues. If you decide to change your video display driver so you can resize your TV image, you MUST write down this current setting before changing to the Standard VGA Driver. If you change this setting and do not know what the old setting is DO NOT call AITech Tech Support because we cannot help you. You must call the maker of your computer system to find out what the original setting is so you can set it back.




Restore the Driver                                         

When you are ready to set your system back to regular use restore the driver to its original settings.

  1. Click Start - Programs - AITech Scan Converter - Restore Display Driver - Click OK


    Figure 20 - Restore dialog

  2. Click OK to continue

    Figure 22 - Warning

  4. Click NO because you do not want to proceed doing something that is not recommended.

Position Controls                                         

To bring up the position controls right click on a blank area of your desk top - click Properties at the bottom of the menu - click on the TV Out Tab as shown below.

Figure 23 - TV Out card

It is not recommended that you use the TV out button. This will make several changes to your system without you being able to note the current settings. If you have read the System Setup section and followed those instructions you have already made the necessary changes to enable your scan converter to work properly for you.


Television Image Quality              

It is important for you, the new owner of an AITech scan converter, to understand that your $200 television cannot do the work of a $3,000 (or even $2,000) VGA computer monitor. A (relatively) inexpensive TV does not have the bandwidth (electronic capability) to display the fine text used in Windows and Windows applications. The text you see under the Windows 95/98 desktop icons is the finest text you will see in Windows. Unfortunately this is the first thing you see when you test out your new scan converter. Please use your scan converter for the purpose you purchased it for before you decide that the output to the TV is not what you think it should be.


You are probably looking at the very fine text that is under the folders and icons on the Windows Desktop. This text is about the finest text you will find displayed in Windows. A TV does not have the capability of displaying fine text clearly on the screen. If it did we would all be using cheap TV's on our computers instead of expensive VGA monitors. What you see displayed on your TV screen is a function of that TV. Some TV's are better than others, and this is not always a function of the cost of that TV. There are several controls in the TV that can enhance the display you see. Adjusting for color, sharpness, contrast, and brightness can help enhance the image coming from the computer.

A VGA monitor of a given size will cost ten to fifteen times that of a TV. A 21 inch TV costs about $200 while a 21 inch monitor will cost you about $3,000. The TV does not have the ability (band width) to make the changes that would allow you to see fine text clearly. You can opt for using large text within Windows. In most cases this display ability will not be a problem for you. Most likely you will be using this for presentations using applications like PowerPoint, or you will be playing games, showing pictures, working with graphics, or surfing the web. For these applications your scan converter will work well for you. It is only in the applications such as word processing, databases work and the like that you will have a problem with the fine text. This can be corrected by choosing large block or bold fonts for your presentation.

There are several things you can do to enhance the fonts on your system if you need to make presentations with programs that have smaller fonts.

Internet Explorer                          

You can select a larger font for displaying the Internet pages you are showing on the TV. Click View - Fonts - and select a larger font to your liking. Note that Medium is the default font size for the normal screen view.


Figure 24 - Setting the font size in IE 4.0

Windows Desktop                                         

In Windows you can specify the font you use for the different areas of the Windows Desktop. To get to your Display Properties just right click a blank area of your desktop - click Properties at the bottom of the menu - and click the Appearance tab at the top of the dialog box as shown below.

Figure 25 - Selecting the Icon properties

Please note the graphic above that shows you how to set the font for the different areas of the Windows. Note the Item list shown dropping off the bottom. This list will allow you to change the appearance of virtually all areas of your desktop. For the purpose of these instructions you will only be interested in changing the font size for the Icons.

Figure 26 - Setting the Icon font size

The graphic above shows you how to change the size of the font. Select the size you think will work and click the Apply button. If this setting is not suitable for your needs choose one higher or lower that you like better. Note that the default font size is 8 point text. Standard printed text is 12 point. The list goes up to 18 point text but this setting may be too large. Click the OK button when you find a font size that you like.
