Solution
My touchpad won’t power
on.
The touchpad is not
connected to a PoE switch.
•
Connect the touchpad to a
switch that supports 802.3at
PoE.
•
If a PoE switch is not
available, use a PoE injector
(sold separately) to power
the unit.
My touchpad isn’t receiving
an IP.
The connected network is
not DHCP enabled.
•
Swipe from the left corner
to the right and press
the refresh button. It can
sometimes take up to 60
seconds to obtain an IP.
•
Set the touchpad to static IP
by selecting the
Set Static
IP
slider and providing IP,
subnet, gateway, and DNS
server information.
