In case of the USB Watchdog hardware performance testing the Reset button is connected to the computer motherboard via the USB Watchdog device with the help of special Watchdog cable. The appearance of the USB Watchdog device is displayed in the figure:

Special four-pin connector is installed on the USB Watchdog device to connect the Watchdog cable.

Connect the USB Watchdog hardware performance tester as follows:

  1. Make sure that power of motherboard and video capture card is off.
  2. Connect the USB Watchdog device to USB connector on the motherboard.

  3. Connect the Reset button cable to the four–pin connector of the USB Watchdog device with the help of a pair of contacts (1/0 or 2/0).  Connecting the Reset button cable to the USB Watchdog device is exemplified in the figure.

    Attention!

    Cables are to be connected to the video capture card taking into account the positioning of the main wire of four-pin connector.

    Note

    To specify the positioning of the main wire (earth conditioned «–/–») the multimeter may be used in the resistance test mode. In this case the main wire is determined by 0 resistance value between contacts
