USB DRIVER DOWNLOAD

With your new camera you will receive a CD-ROM (S-SW23) with USB drivers for Windows 98. These drivers, when properly installed, allow your computer to see your camera as a disk drive, allowing you to download your images. However, if you do not have your CD-ROM, for whatever reason, you can download the USB drivers from this page.

PLEASE NOTE: These are Windows 98 drivers only. Most recent versions of Windows and MacOS will automatically recognize your camera as a disk drive when you connect it to your computer. If your computer does not have Windows 98, you may see an error message during installation (see below for details). You only need to download and install Pentax-supplied drivers for Windows 98.

INSTRUCTIONS

You must download and install these drivers before you attempt to connect your camera to your Windows 98 computer.

  1. Download the usbsw23.exe self-extracting driver file and save it on your computer's hard drive (the download link is at the bottom of this page). The desktop is a good place to save it where you can easily find it.
     
  2. Double click the usbsw23.exe file to extract its contents.


    Click UNZIP to complete the extraction.


    This alert will tell you when the extraction is complete. Click OK, then close the Self-Extractor window by clicking the CLOSE button.
     
  3. Now, you will have a folder on your C: drive called usbsw23 as shown below.


    Double click the usbsw23 folder to open it.
     
  4. In the usbsw23 folder, double click the Setup.exe icon, circled below, (it might just be called Setup) to begin the installation of your USB drivers.


     
  5. Follow the on-screen prompts to complete the installation of your USB drivers.

    PLEASE NOTE: These are Windows 98 drivers only. If your computer does not have Windows 98, you may see the following error message, and you will not be able to complete the installation:


    Remember, most recent versions of Windows and MacOS will automatically recognize your camera as a disk drive when you connect it to your computer. You only need to download and install Pentax-supplied drivers for Windows 98.
     
  6. Upon successful installation of your USB drivers, you can connect the camera directly to the computer with your USB cable. The computer will then see the camera as a new removable disk drive in the My Computer window.
