On the MKUSB there is a small jumper.

This only goes in place when you want to power a board off the USB connector.

Never have the jumper in when the board is powered by the Power Dist Board (PDB)

This picture above shows the 5 volt Jumper Out.

this one shows the 5 volt output jumper in. so this will supply 5 volts the the board you connect to the cable.

Make note of the #1 pin on the MKUSB Pointing away from you it is the upper left pin

this is where the Red wire connects. There is another pin 1 but that one is sideways..:)

Now you need the MKTOOL

Make sure you have the MKtool and the latest version.

you can get the tool here

MKTOOL v.74b

If this is not the latest version that is fine we will show you how to update it in a minute.

Once you have the MKtool downloaded and installed on your PC

Plug the MKUSB into your PC with the USB Cable and Windows should find it as a USB to serial converter.

Look in your Device manager and verify the Com port.

This one is using COM Port 15

Make sure the Jumper is Out on the MKUSB for now.

Now connect the MKUSB to the FC making sure the FC is on something safe and nothing can short it out.

Put the red side of the cable on the #1 pin on the FC

Install the jumper on the MKUSB so it powers the FC off the USB

You should see some led's light up on the FC and end up looking like this

The lights on the MKUSB will flash randomly.

But Red an Green solid are good on the FC.

Now making sure your FC is safe and secure not to fall off your bench and shock the cat

Start the MKTOOl

once it opens it may take a bit for it to start running but you should see a screen like this.

The errors shown on the screen are normal at this point. If you hit details you will see

the FC is complaining about no BL's and no Radio. which is normal,(you have no BL's and you have no Radio connected, yet. :) )

Make sure it has the correct name of your model and the spinning slash is spinning :)

you can click the 3d button and see the MK move with your movements.

If you need to change the Type of model hold the Alt key and click settings. for Non ARF'd systems.

Dont worry about how its orientated or that its not level that will all come latter after you calibrate.

If you are unable to connect to the FC first check that it is trying to use the correct COM port.

so Click on Firmware and update Terminal...

Select the Com port we found in the Device manager.. it may be different on your system.

then hit Debug to go back.

To verify you have the correct version of the MKtool click on the magnifying glass in the Terminal window.

(its right next to the red triangle )

click on the Mikrokopter -Tool Tab

click Update Version-list

if the top one is not the same version you currently have

Click Download

it will download the tool into the /downloads folder where every you installed the MKtool to start with.

If it is the same just hit close and you are done.

Now your FC and Power Dist are both Tested and working.

You have the MKtool and its the current version.

Lets move on.

Testing the FC on the PDB

Find the black and white Molex connector in your kit.

Make sure no voltage is on your Power Dist ring we tested earlier.

Make sure your MKUSB jumper is now Out

Plug one end of the Molex connector into the FC and the other into the PDB

The connector will only go in one way to double check the key before pushing too hard.

Place the FC in such a way it will not have any contact with the power Dist.

This is vey important!!

More boards are broken on the bench than in the Air.

Be very safe and Clean.

I'm using a frame ring with some standoffs in place for testing. You can set the FC to the side but it must be with the gyros pointing down.

Now Making sure your Jumper is out on the MKUSB

Apply voltage from your Power supply. 12 volts will work better at this point. 9 volts is ok but you may get an under voltage error.

You should see the LED's light up on the FC and end up Red and Green solid. This is good!!

The BL's should now be all solid Green at this point. Be very careful looking. :)

now Open up your MKtool

You should see now that it stopped complaining about the BL's Click on Details

No Receiver found because we have no Receiver installed yet.. :)

This is awsome all is good!!!

you can then click on the Red arrow pointing left and see the Number of BL's found

and then one more time you can see the temperature of each BL.

Now you have a fully tested and working Flight Controller and Power Dist Board with BL's

Plus you have learned Mikrokopter Terms and tools for troubleshooting and getting you through the rest of your build.

Continue on to the Navi board set up Next on the list.

Have fun!!! enjoy your build!
