Serial Communication
Figure 3: ESCCPC5V
The most common cable choice for the any GTT display, the Extended
Communication/ Power Cable offers a simple connection to the unit with
familiar interfaces. A DB9 and floppy power header provide all necessary
input to communicate to and power your display.
I2C Communication

For a more flexible interface to the GTT, especially with the I
2
C protocol,
a Breadboard Cable may be used. This provides a simple four wire
connection that is popular among developers for its ease of use in a
breadboard environment.
USB Communication
Figure 5: EXTMUSB3FT
The External Mini-B USB Cable is recommended for USB communication.
It will connect to the Mini-B style header on the unit and provide a
connection to a regular A style USB connector, commonly found on a PC.
Power
Figure 6: PCS
The standard power cable can be used to apply power to the GTT, either
in conjunction with the ESCCPC5V cable, or via a direct connection to the
Alternate Power Header. It connects to a standard PC power supply.
Mass Storage
Figure 7: EXTMUSB3FT
An External Mini-B USB Cable may also be used to access data within the
onboard SD card when removing the card itself is not possible. This
connection also provides power to the GTT and can be more convenient
than moving the SD card from one location to another.
