KMtronic Cable

Starting from version 3.50, APT supports a new type of Canon/Nikon shutter cable. It is very easy to make, requires no electronics skills and no soldering! Other advantage is that there is no need of Serial-to-USB adapter, the cable is connecting directly to an USB port. Once the cable is ready, the option KMTronic based shutter cable in Main Settings tab has to be enabled.
You need three main things:
2. The cheapest possible shutter control for your camera
3. USB cable
The other things you will use are: something to cut wires, isolation band and a screwdriver.
Step 1
Cut the remote controller cable near to the button in order to get longer cable attached to the connector. Remove the isolation from the there wires and connect the cable to the camera. Turn the camera on. Start connecting the wires in a pair to see which pair will shoot an image (in this case it is the Blue and the White). There is no risk to damage anything! This is the same what the remote controller does ;)
Step 2
Cut the unneeded wire and isolate it with some band. You can use the plastic bag - cut one of the ends like on the picture ( smaller cut would be better :) ). If there is need shorten a bit the not isolated parts of the wires and connect the them to connectors C and NO (leave NC free) using the screwdriver. The green LED will be turned on during exposure so you may want to be visible...
Step 3
Isolate the board somehow. On the picture is given one option. Other is to use white isolating band (white in order to see the green LED) and wrap both cables and the board in one package. If you have suitable plastic box, it can do the job...
Do no use metal box!
