The Mode Switch determines what payload will be run.
On boot the Packet Squirrel will run the selected payload, or enter Arming Mode.
Selected at boot
The payload is selected when the Packet Squirrel boots.
Changing the position of the Mode Switch will not change payloads until you reboot.
Reboot the Packet Squirrel automatically by holding down the pushbutton at the top of the device for 5-10 seconds.
Alternately, you can simply unplug the Packet Squirrel and plug it in again to reboot it.
