Simple LSDJ Keyboard Guide

UPDATE! Color Set Images will be posted here

There is a lot of information out there about making an LSDJ keyboard, but I found most of it rather confusing (as im sure a lot of you have). With the help of my friend Capcomposer, we figure out how to make one. Once we were done using a digital multimeter to finish out first one, I created 3 more with nothing but memory. So now im gong to show you how to do the same thing.

As of now, I have created 4 keyboards by just remembering the 4 color combinations you need to connect. Im sure there is some PS2 keyboards out there that are different, but I have not yet found one this didnt work with (granted I have only done 4)

Shall we begin? (you can probably start heating up your soldering iron now, this wont take long at all) For this guide we will be using a DMG-07 cable (4 player link box) because it carries the 5v power source needed top power the keyboard with no extra modding. I am also told that the official DMG-04 (2 player link cable) will also work the exact same way. ( I have not used one yet, so I can not conform this)

The first thing we are going to do is open your DMG-07 and cut the cable off near the PCB (so that the cable is as long as it can be). You can remove the metal weight from the wire, but you can optionally leave on the little rubber cable guide (you'll see later). You will now see 5 wires, brown, blue, green, yellow and red. Next you will strip the wires, all of them but red, you can just clip the red wire off as seen in the pic below. Your DMG-07 should be left with 4 wires.

Next open your keyboard to get access to the PS2 cable, you will cutting this cable leaving about 5 inches running off the small PCB inside (length may differ from keyboard to keyboard depending on where you cable exits the keyboard casing, just make it short enough to where you DMG-07 cable will run into the keyboard casing once connected)

Your keyboard may have 5 or 6 wires in the the cable depending on the pin type of the PS2, but you will only be using 4 wires, and the colors have been the same for me in all keyboards. Look for the grey, brown, red and yellow wires. These are the only 4 wires you will need, all others can be cut off as seen below.

At this point, you have 4 wires from your DMG-07 cable, and 4 wires from your keyboard PS2 cable. Tin the wire tips with your soldering iron and connect them as follows:

DMG yellow to PS2 red
DMG green to PS2 yellow
DMG brown to PS2 Brown
DMG blue to PS2 grey

Now with your wires connected you can start closing up. First wrap each solder point in electric tape individually (no need to be over concerned with looks, this part will be inside your keyboard)

Now you can tape up the whole mess of wires and not worry about cross talk. Once all taped up, you can lead the cable back out of the keyboard, and is you decided to keep the rubber cable guide on the DMG-07 cable, you can use it in your keyboard case (different keyboard cases may require a lager hole to it to fit, nothing a little dremeling cant do)

Now you can close it all up and ENJOY!!! Hope you enjoyed my guide, let me know if it helps.

Stay tuned for a guide on painting this sucker!
