Table 8: Pinning Control Surface connector
The power-supply for the control surface comes through the 15 pin cable. It's very important to never
extend the cable any further than the maximum specified length of 5m. This is also the length of the
cable delivered with the package. If the voltage drop on the +5 volt lines becomes to large the control-
surface won't function properly.
