1. Kit Install Overview

The basic idea of the LED kit is to replace the missing or faulty EL panels and MVS-ELA board in  Neo Geo cabinets.

The new control board can be setup for 2,4 and 6 slot games and connects to the MVS-ELA port on the side of the MVS 2,4 or 6 slot game board.

If you have the old cable you can still use this, or you can buy one with the kit.

1. Position the control board and secure it to the cabinet.

2.Align the panels to match your marquee.

3.Double check all connections and power up the game. The control board will run through a self-test and light up each panel in turn.

Once the system is running, only the panel for the game selected with light up.

That’s it. Tidy up those cables and enjoy your LED mini marquee’s.

3. The Data Connection, MVS-ELA

Next we need to get the data from the MVS to the new control board. This is the 8 pin connection on the side of the mvs next to the two 13 pin connections for the credit displays. If you have this we can use it on the new kit, just follow it up into the back of the marquee and it should be connected to the old MVS-ELA board. Remove the old board and connect the wire to the 8-pin port on the new control board. Although it only used 6 wires at the MVS end the ELA lead end also has 5v (red) and ground (black) we want to make sure the black wire goes to the pin marked GND on the new control board.

If you do not have the original ELA lead you can buy a new lead with the kit. On both ends we want to make sure the black wire is to the left when connecting to the MVS and the new control board.

Secure this in place.

4. The new control board

The new control board is Arduino based and socketed so it’s easy to replace in the future. The Arduino uses Pulse Width Modulation to control the brightness of the panels . The board has the option to show what panel should be on with LED so you can diagnose any issues you might have with data connections or panel order. The panels use screw terminals, so you can easily cut the wires to length once everything is in place. 

The control board comes with 4 feet so you can mount this to any spot in the cabinet as long as the provides wires are long enough. Once you have set the brightness there is no reason to need access to it again.

 

We can now connect the data cable to the control board and start to look at the panels.
