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. There are
the following  connectivity options:

Connection via ATX-/BTX-Adapter cable

Connection direct to power supply
