1. Insert the Matrix Orbital Cd-ROM into the Cd drive.2. Locate the file "mogd.zip". It should be in the “Download” directory.3. Unzip mogd.z

2. Wire the connector to the power supply. On most connectors the RED lead will go to +5V and theBLACK lead to GND. Do not connect the GLK24064-25 to

To experiment, reverse the connector and see if it generates a more logical set of characters. Ultimately, theprogram in the micro-controller will hav

To lock down the memory chip, solder the jumper in the ’red box’ and cut the trace where the red ’X’is. This will lock down the memory chip, preventin
