For mounting the MatrixPortal S3, you will need:

• MatrixPortal S3
• MatrixPortal Mount
• 2 x M2.5 x 10mm Screws
• 2 x M2.5 Hex Nut

Insert the MatrixPortal so that the 2x10 IDC connector goes into the rectangle. It should be inserted from the side with the raised arms so that the holes line up. Insert the M2.5 screws through the MatrixPortal and out the holes in the mount.

Attach the M2.5 Hex Nuts and tighten snugly.

For this part, start with four 16x32 matrices.

You will want to lay them out side-by-side so that the input connector is to the right and the text appears upside down.

For connecting the matrices, you will need:

• 6 x Connector Bracket
• 10 x M3 x 10mm Screws

Starting from the left, place a connector so that it sits on the alignment peg and is aligned to the screw holes. Install 2 screws to hold it in place. The screws should be snug, but not overtightened.

Do the same for the other left connector bracket and both middle connector brackets.

For the two right connector brackets, only install a screw in the right hole. The holes without screws will be used for the MatrixPortal S3 Mount.

Now you should have all 6 connector brackets attached with the exception of the right two brackets missing their left screw.

To connect the MatrixPortal Mount Subassembly, two of the screws can be anywhere from 10mm to 16mm. You will need the following:

• MatrixPortal Mount Subassembly
• 2 x M3 x 10mm Screws
• 2 x M3 x 10mm-16mm Screws

Place the MatrixPortal Mount Subassembly so that the 2 raised arms go into the holes without the screws.

Install the shorter screws into the part of the subassembly that covers the center holes of the matrix.

Install the longer screws into the holes above the connector bracket.

Start with the panel with the cutout holes. You will also need 7 panels without holes further down.

With the front side of the matrices facing towards you, place the panel so that it's almost in its final place and slide the right side onto the connector bracket. You may need to flex the panel a bit to get it past the buttons.

Continue sliding the panel to the right until the panel's left side is able to clear the connector bracket underneath it and slide it onto its respective bracket.

Go ahead and center it so that the holes all line up.

The regular panels are easier to slide on from one end or the other until they sit flush in the middle.

When sliding them on, be sure that the lip of the panel faces the same direction as the one with cutout holes.

Continue sliding on the remainder of the panels until all 8 are on the message board.

To install the sides, you will need the following:

• 2 x Side Panels
• 4 x 10mm Screws
• LED Acrylic Piece or Pieces

Start by connecting one side. To get it past the alignment peg, you may need to flex parts slightly. Install 2 screws once it is in place.

Slide any acrylic pieces you have into the message board from the side without a panel. The acrylic should be installed with the shiny side facing towards the matrices and the matte side facing towards the outside.

Install the second side panel. It's easiest to get it over the alignment peg first and then get the acrylic into the slot. Install 2 more screws.

For the wiring, you will be using 3 of the shorter ribbon cables and 2 of the power cables that came with the matrices.

Start by connecting the 4 panels together using the 3 shorter ribbon cables.

When connecting the wires to the MatrixPortal S3, place the flatter sides of the spade connectors together and insert them into the 5V screw terminal. Make sure the screw is fairly tight.

Connect the ground wires to the other terminal.

Connect the 4 power plugs to the power inlet of each panel. You may have to try a few different ends until you find one that reaches the furthest plug well enough.

Connect the longer black ribbon cable between the MatrixPortal and the input of the right-most panel.

The connector brackets have built-in zip tie holders designed to fit zip with a width of about 3mm or smaller.

When zipping down wires using the connectors, leave the zip tie loose for now. You will be feeding a larger zip tie between the smaller ones.

Place a second zip tie across from the first, even if you aren't holding any wires in place.

You will want to carefully fold the cable back and forth until it sits neatly between the 2 connectors.

Take a larger zip tie (8 inches or longer) and loosely connect it between the smaller zip ties so that it looks a bit like a chain.

Tighten the smaller zip ties first.

Then tighten the larger zip tie, which will hold the ribbon cable in place.

Clip off the ends of the zip ties with flush cutters.

Do this for the other sets of connectors.

You may want to carefully fold and secure the ribbon cable around the MatrixPortal so that it doesn't stick out the back.

You can also use the arms of the MatrixPortal Mount for securing wires.

That's it! You should now be done.
