2. Make the connections.

a. Connect the four pin female header of the Communication/Power Cable to the

Communication/Power Header of your LK162A-4T.

b. Insert the male end of your serial cable to the corresponding DB9 header of the

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.

C Connections

A more advanced connection to the LK162A-4T 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 LK162A-4T in I

C

mode, get started with the guidelines below.

1. Set the Protocol Select switches.

I

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 LK162A-4T 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.

This time you're on your own. While there are many examples within the Matrix Orbital
AppNote section,

, 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.
