  • Page 11: Application Examples

    2.5. Application examples 2.5.1. PC reset To reset a PC via the Watchdog-Stick, there are several connectivity options; Connection via Reset-Button If the PC is not equipped with a Reset-Button, you have to reset the PC directly via power supply. Therefore the connection cable between the power supply and mainboard has to be cut trough and connected to the Watchdog-Stick.
  • Page 12 2.5.1.1. Connection via Reset-Button If the PC is equipped with a Reset-Button, this button can be activated directly by the Watchdog-Stick. If a timeout occurs, the watchdog will activate the Reset- Button. Therefore, the connection cable between Reset-Button and Mainboard must be connected with the 1.
  • Page 13 If the PC is not equipped with a Reset-Button, you have to reset the PC directly via the power supply. Therefore, you have to disconnect the power supply plug from the mainboard and connect this plug to the slot side of the "DEDITEC ATX20/24 Connection Cable" (optional accessory for the Watchdog-Stick). After this, connect the plug of the "DEDITEC ATX20/24 Connection Cable"...
  • Page 14 5. Disconnect the power supply plug from the mainboard and connect this plug to the slot side of the "DEDITEC ATX20/24 Connection Cable" (optional accessory for the Watchdog-Stick). After this, connect the plug of the "DEDITEC ATX20/24 Connection Cable" to your mainboard. Connect the both lateral protruded wires with the 2.
  • Page 15 2.5.1.2.2. Connection direct to power supply At some PC systems, like e.g. Dell, the pin assignment and the form factor of the power supply plug diverges from the ATX-/BTX- form factor. At this systems you have to cut trough the "PS_ON'" Cable by yourself and connect it with the 2. relay (opener-relais) of the Watchdog-Stick.

  • Page 18 3.1.2. Configuration 1. Open the USB-Watchdog stick which you want to configure. Note: If you want to use more than one USB-Watchdog-Stick on your pc system, you need to configure them with the DELIB Configuration Utility and give every USB-Watchdog Stick a unique Module-Nr. 2.
  • Page 19 "DapiWatchogEnable". State "Retriggered": This state can be achieved through the command "DapiWatchdogRetrigger" State "Timeout": This state will be used if the Global Watchdog Timeout occurred. For this state two relay settings can be configured. The first setting will be used immediately after the timeout. The second setting will be used after the configured timeperiod (in milliseconds).
