Type A HDMI Port
The HTT uses a Type A HDMI 1.0 port to receive video data from its host/source and is only compatible
with unencrypted video signals. HDCP video signals are not supported.
When properly connected, the HTT will require 5V at 55mA (minimum) from the HDMI source in order
to read the display’s EDID settings.

Mini-B USB Communication Connector
The USB header must be connected to the host in order for the touch screen to be functional, as touch
communication occurs over USB. The Mini USB header is also used to access the HTT’s touch firmware,
and configure certain HTT settings through the HTT Utility Program. If necessary, up to 500mA of power
can be provided through the Mini-USB header to power the HTT.
