Moog Opus 3 MIDI kit retrofit Installation manual Rev A03.1

Welcome to the metric system zone. Here we work with precision things and all dimensions are metric. 1" = 25.4mm.

This kit is pretty universal and contains two different set of screws and full set of ribbon cables. For MOOG OPUS 3 you will have unused 4 wood screws and 1 ribbon cable. 

Installation:
To your good usability select the friendly place to mount the LED, MIDI connector, button and PCB.
Drill all holes that required and mount connector, LED and button before soldering wires. 

Drill dimensions:
For PCB drill holes 3.5mm.
MIDI jack (DIN5) = 18mm.
LED holder = 6mm.
Push button = 12.5-13mm.
Be careful with drilling hole for button, it have so small range to get hole too big.

Board dimensions and distance between screws:
Dimensions 102x50mm. Height 14mm with inserted connectors.
Holes diameter 3.5mm.
Mounting outline and hole drills draft for board example sticker paper included.

Do not allow the board to bend, it can break the board. 

All ribbon cables are 90cm. long, enough for placing all connections and you can cut extra length.
Panic button is not included in the kit. In case of panic - enough turn off and turn on the synth. If you prefer to install it part number is E-Switch RP3502MABLK

This picture shown:
First (1) pin/wire on all connectors. First wire will be start from this side.
J2-J4 jumpers that divide common rail for every octave separate or split.
For MOOG OPUS 3 they should be close with solder. If you can't do it clear, skip it and be happy to solder three extra wire to key contact common rail. 
Bottom side jumper J5 should be open for MOOG OPUS 3 
The next picture shows the pinout for X6 connector ribbon cable and pin number of wires:
Same you can see on bottom side of PCB for more convenience.

 You will need to connect wire 4 (GND) with LED and button. All other wires in this kit required only one point of soldering. 

(7) V+ and (8) GND should be soldered on the next points:

So, now time to soldering key contact wires: All next connectors should be soldered to each key contact

Board pinout and MIDI note:

Solder wires to key contacts and common bus. Find key contacts for note C (Do) on the first octave and solder wires from the (BLUE) connector. Starting from wire 1. When you finish it, your last wire will be 12 and note (B) on this octave.  If J2-4 are not soldered, you need to solder wire 13 to common key contact bus. Repeat all this on every octave.
On octave 4 (RED),  also start from wire 1 - C (Do). Wire 13 should be soldered to key contacts common bus. Wire 14 (C) should be soldered to last key C.
