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.
