Specifically, the instructions are for the assembly of kits v2 (version 2), those using the All-In-One circuit and the PiScreen 3.5' display. If you have a older kit v1, based in the 2in1 circuit and the PiTFT 2.8' display, you better should read [[Building a Zynthian Box using an official Kit | this tutorial]].

=Connecting everything=
=Connecting everything=
The new Zynthian Kit 2 is designed to use JST connectors, so connecting everything is really straight-forward:
* Connect the Main Ribbon Bus cable to the RBPi's 40-pin header and also to the All-In-One module
[[File:IMG_4741.JPG|600px]]
[[File:zynthian_ui_legend.png]]
[[File:IMG_1474.JPG|600px]]
* Connect the 4 double JST cables to the 4 controller connectors on the All-In-One module (CTRL1, CTRL2, CTRL3, CTRL4)
[[File:Controller_dupont_wires.jpg|600px]]
[[File:IMG_4744.JPG|600px]]
[[File:IMG_1479.JPG|600px]]
* Connect the 2 JST cables from the MIDI connectors to the MIDI-IN and the MIDI-OUT/THRU connectors on the All-In-One module. Note that currently only 2 connectors are available in the official aluminum case, so you have to choose what do you prefer: MIDI-OUT or MIDI-THRU ;-)
[[File:IMG_1465.JPG|600px]]
At this point, your Zynthian Box should look something like this:
[[File:IMG_1409.JPG|600px]]
* Connect the 4 x Controller Modules following the right numbering: from top to bottom and from left to right.
[[File:2in1_dupont_wire.jpg|600px]]
[[File:zynthian_controllers.png|600px]]
[[File:IMG_1412.JPG|600px]]
* Connect the Jack connector to the auxiliar audio-out connector on the HifiBerry soundcard. It's the 3-pin JST connector that you soldered before:
[[File:IMG_1489.JPG|600px]]

If you are using an older SD image that is not pre-configure for the Kit v2, then you should configure your Zynthian Box's hardware using the [[Configuration_Users_Guide|webconf tool]]. These are the adjustments you have to do:

===Test the Controllers===
===Test the Controllers===
If you get the Zynthian UI, then you should start by testing that your controllers are working OK.
If you get into the Zynthian UI, then you should be in the 'Layer Selection' screen. Let's start testing that your controllers are working OK.
1. Push 'select' to create a new layer. You should get into the 'Engine Selection' screen.
[[File:IMG_1563.JPG|600px]]
If it doesn't works, try pushing the 'LS' controller. Perhaps you have cross-wired the 3 & 4 controllers and in that case, you have to fix the wiring. If it doesn't work, try pushing the other two controllers and rotating the controllers. If something happens, most probably you have reversed the wiring order when connecting the controllers, or perhaps you have changed some wires while connecting the main ribbon bus. Double-check the wiring again.
If it doesn't works, try pushing the 'snapshot' controller. Perhaps you have cross-wired the 3 & 4 controllers and in that case, you have to fix the wiring. If it doesn't work, try pushing the other two controllers and rotating the controllers. If something happens, most probably you have reversed the wiring order when connecting the controllers. Double-check the wiring again.
2. Rotate the 'SELECT' controller to select the engine you want to start.
2. Rotate the 'SELECT' controller to select the engine you want to start for the new layer.
The selector must go down when rotating clockwise and go up when rotating counterclockwise. If the rotation sense is reversed, you should check the wiring.
The selector must go down when rotating clockwise and go up when rotating counterclockwise. If the rotation sense is reversed, you should check the wiring.
3. Push 'BACK'. You should get into the 'Admin' screen. Push 'BACK' again to return to the 'Engine Selection' screen.
3. Select the ZynAddSubFX engine, select channel #1, bank and preset. You should get into the 'Instrument Control' screen.
[[File:IMG_1568.JPG|600px]]
4. Rotate every control to test that it works and that the rotation sense is correct.
If some controller doesn't work correctly, check the wiring again. You could try to figure what is happening by analizing the observed behaviour.
If some controller doesn't work correctly, check the wiring again. You could try to figure what is happening by analizing the observed behaviour.
5. Push 'BACK'. You should go back to the 'Preset Selection' screen.
6. Push 'Layer' again to return to the 'Layer Selection' screen. Try to create another layer following the same procedure.
[[File:IMG_1584.JPG|600px]]
7. From the "Instrument Control" screen, push 'Snapshot' to get into the 'Load Snapshot' screen. Push 'Snapshot' again to 'Save Snapshot'. Push 'BACK' to return to the 'Instrument Control' screen.
If everything is working OK, then you should read the [[Zynthian_Users_Guide|User's Guide]] and start enjoying your Zynthian Box, but before that ...
===Test the Audio Output===

1. Connect the audio output (RCA or Jack connectors) to your amplifier or auto-amplified speakers.

=Close the Case=
=Final steps=
When everything is working OK, it's time to close the case, but first ...
===Insert the knobs===
You should insert the knobs into the encoders before closing the case. This will avoid forcing the encoders too much as otherwise, you could break them.
Follow these simple steps and you wouldn't have any problem:
* moisten with water or saliva the encoder stem
* press the encoder with the finger from the rear while pushing the knob from the front until is completely inserted
===Close the case===
Once the knobs are in its place, take your time to see how to bend and drive the cables to get a good fitting when closing the case.
