11.  PC Connection
The Combiboard has a serial interface like the control board of the QuadroCopter. The electron-
ics can communicate with a computer via those interfaces.
Using the jumper „X11“, the serial interface of the combiboard can either communicate with the
control board of the QuadroCopter (2nd internal interface) via the 26-core interface cable or be
switched to the interface connection „X12“. This function is used for future expansions and is
currently without function.
When the contacts 1 and 2 are connected with a jumper, the interface at the control board of the
QuadroCopter is active. When the contacts 2 and 3 are connected with a jumper, the interface at
the Combiboard („X12“) is active.
For the pin assignment of the interface plug „X12“, see figure 13.
If the computer interface in the computer does not have sufficient power supply for
the electronics in the QuadroCopter, the drive battery must be connected to the
QuadroCopter.
