Watchdog Configuration Page

The Auto Reboot Ping feature allows uSwitch to automatically detect failed equipment and reboot or restart it without
human intervention. You may set one to three IP addresses or URLs to be periodically tested for each relay. If the uSwitch
determines a communication problem exists between any or all of the specified devices, the selected relay will
automatically cycle, switching power on and off to reboot a device or devices whose power has been wired across the
relay.

The Watchdog feature has been successfully deployed with: IP cameras, kiosks, web signs, cellular routers, Servers, DSL
and cable modems, RTUs, control sensors, a variety of Smart Grid technologies, etc.

The following parameters are effective only when uSwitch is set to

Auto Reboot Ping

mode (in the Relay Configuration

page).
