Matrix Orbital GLK19264A-7T-1U - Manual (Page 9)

4 Command Summary
2. Make the connections.
a. Connect the six pin female header of the Extended Communication/Power Cable to the
Communication/Power Header of your GLK19264A-7T-1U.
b. Insert the male end of your serial cable to the corresponding DB9 header of the Extended
Communication/Power Cable and the mate the female connector with the desired
communication port of your computer.
c. Select an unmodified floppy cable from a PC power supply and connect it to the power header
of the Communication/Power Cable.
3. Create.

MOGD# or a terminal program will serve to get you started, and then you can move on with
your own development. Instructions for the former can be found below and a variety of
application notes are available for the latter at
www.matrixorbital.ca/appnotes .
I 2 C Connections
A more advanced connection to the GLK19264A-7T-1U is provided by the I 2 C protocol setting. This is
best accomplished using a breadboard and the Breadboard Cable. Power must be supplied from your
breadboard or another external source. To dive right into your application and use the GLK19264A-7T-
1U in I
2 C mode, get started with the guidelines below.
1. Set the Protocol Select switches.

I 2 C: Ensure that the two I 2 C jumpers in the corresponding protocol box are connected while all
others are open.
2. Make the connections.
a. Connect the Breadboard Cable to the Communication/Power Header on your GLK19264A-7T-
1U and plug the four leads into your breadboard. The red lead will require power, while the
black should be connected to ground, and the green and yellow should be connected to your
controller clock and data lines respectively.
b. Pull up the clock and data lines to five volts using a resistance between one and ten kilohms on
your breadboard.
3. Create.

This time you're on your own. While there are many examples within the Matrix Orbital
AppNote section,
www.matrixorbital.ca/appnotes , too many controllers and languages exist to
cover them all. If you get stuck in development, it is possible to switch over to another protocol
on the standard board, and fellow developers are always on our forums for additional support.
