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.

Barrel Jack Power Adaptor
A Barrel Jack power adaptor is available on the HTT70 as standard to provide power to the display.
When choosing an adaptor, please ensure it uses a 2.1mm x 5.5mm center positive barrel jack that
conforms to the voltage and current requirements of your display. Please consult the Power section for
details.

Alternate Micro MATE-N-LOK Power Adaptor
Some applications may prefer a lower profile 2-pin power header option as opposed to the standard
Barrel Jack. The HTT70 can be populated with a versatile Micro MATE-N-LOK 2-pin header as an
alternative to the standard barrel jack. The Micro MATE-N-LOK 2-1445057-2 header used can be mated
to a Micro MATE-N-LOK 1445022-2 or similar.
When choosing an adaptor, please ensure that it conforms to the voltage and current requirements of
your display. Please consult the Power section for details.

Getting Started
When connecting your HTT display, power must first be applied through the barrel jack or optional
Micro MATE-N-LOK header. Once powered, connect the HTT to your source HDMI cable.
Windows
When connected to Windows, the HTT’s resolution will be automatically detected and set through the
on-board EDID. The HTT display should immediately appear in display settings. No additional software
setup will be required.
Raspberry Pi
Some setup will be required before the display can be used with a Raspberry Pi unit. The HDMI
resolution will have to be configured through the config.txt file (located in /boot/config.txt).
The following modifications can be made to the Raspberry Pi’s config.txt file, forcing the HTT’s
resolution settings:
#Set the Monitor mode to DMT.
hdmi_group=2
#Use a custom resolution.
hdmi_mode=87
#Use an 800 x 480 resolution @ 60Hz
hdmi_cvt= 800 480 60 6 0 0 0
#Deliver max current through USB
Max_usb_current=1
The configuration lines listed above will configure the Raspberry Pi to drive an 800 x 480 display at 60Hz.
TinkerBoard
The HTT will be compatible with TinkerOS-Debian. Once connected, the Tinkerboard will autodetect the
HTT’s display settings. No further software configuration is required.
The HTT is not fully compatible with TinkerOS-Android Marshmallow.
BeagleBone
The BeagleBone board will autodetect the HTT’s EDID display settings automatically. No further
software configuration is required.
