Skycube: Preparing the Download cable
For downloading software into the Skycube board or controlling modular robots from the PC, the TTL-232R-5V FTDI cable is used. This cable is connect on one side to the USB port in the PC and on the other side to the Skycube board, by means of a three-pins header. Originally, this cable comes give a six-pin female straight header. It has to be changed by a three-pin header for connecting to the Skycube board. This process is reversible, so that the original cable can be recovered anytime.
Modifying the cable
Step 1: Remove the 6-pin header
The 6 wires should be pull out one. Using a flathead screwdriver lift the tap and pull out the wire.
Step 2: Place the new 3-pin header
Insert the black, yellow and orange wires in the new header. It is very important to connect them exactly in the same way than in the figures. Make sure the header is in the right position, with the tabs facing up (See the pictures).
Step 3: protect and remove the remaining wires
Put insulating tape around the metal pins of the remaining wires to avoid short circuits. Then, bend back the wires until they are paralell to the cable. Put insulating tape around them. The download cable is ready to use!!!
Step 4: Put a label on the 3-pin header
It is important to put a label in the cable to identify the correct orientation for the connection to the Skycube board. This will avoid mistakes.
Connecting to the Skycube board
The three-pin female header is attached to the M6 connector of the Skycube board in the same orientation shown in the figures. To avoid connecting the header in the wrong orientation, it is useful to put a label as shown in the right figure.
