Making sure your matrices are laid out in the correct order can be confusing. Before plugging in any cables, lay them out to make sure they are oriented properly. Each matrix has arrow markings which you can use to help during layout.
- Matrix 1 - This matrix will have the Matrix Portal S3 plugged into its IDC port on the left. Its arrow markings will be pointing up and to the right.
- Matrix 2 - This matrix is placed to the right of Matrix 1. Its arrow markings will be pointing up and to the right.
- Matrix 3 - This matrix is placed below Matrix 2. Its arrow markings will be pointing down and to the left.
- Matrix 4 - This matrix is placed to the left of Matrix 3 and below Matrix 1. Its arrow markings will be pointing down and to the left.
Once you have your four matrices laid out in the correct order you can start plugging in the IDC cables.
Plug the last IDC cable into the left-hand port on the Matrix 3 and the right-hand port on the Matrix 4. This completes the data wiring for the matrices.
Place the center bracket over the intersection in the middle of the four matrices. Use the bracket to make sure that the matrices are aligned with each other. Secure it with four M3 screws.
Use four 2x1 brackets to join the matrices together to the left and right of the center bracket. Secure the brackets with M3 screws.
Use two 2x1 brackets to secure the matrices above and below the center bracket. Secure the brackets with M3 screws.
Gather two power cables that came with your matrices. Plug one of the cables into the two power inputs on the top two matrices. Plug the other cable into the two power inputs on the bottom two matrices.
Secure the positive cable (red wire) into the positive terminal on the DC jack adapter (labeled with a raised +). Secure the ground cable (black wire) into the negative terminal on the DC jack adapter (labeled with a raised -). Repeat this for the second power cable.
Now you can plug both sets of two matrices into 5V 4A power supplies.
