Autopilot Servo Installation, Configuration, and Calibration
10-12 SkyView System Installation Guide - Revision S
Power Consumption Section of the System Planning Chapter for details regarding servo current
consumption at 12 and 24 volts DC.
Circuit Breaker/Fuse
We recommend that electrical power for the autopilot servos be protected with an
appropriately sized circuit breaker or fuse that is accessible to the pilot while in flight.
SkyView continuously communicates with the servos even when the autopilot is disengaged. If
SkyView is operating, but the servos are not receiving power,
PTCH ERR and ROLL ERR will be
displayed in Red on the top bar (AP STATUS area, to the left of the clock). Therefore, we
recommend that the servo power wiring be designed to receive power whenever SkyView is
powered on in routine operation. When the servos are receiving power but the autopilot is not
engaged, the servos draw negligible power.
SkyView Network Connection
Connect the servos to the SkyView network according to Figure 64 and Table 47. Installers
should strongly consider using the SV-NET-SERVO cabling kit (one per servo) for completing the
network connection to the servos in the system. Figure 65 is the recommended pin insertion
scheme for the three D9 connectors present in the SV-NET-SERVO cabling kit.

Unlike other SkyView Network devices, ONLY the SkyView Network data wires are
routed through the 9-pin connector. The servo Power (Red), Ground (Black), and
Disengage/CWS Button (Yellow) wires are not connected in the 9-pin connector. If
these wires were to connect to SkyView Network signals, the SkyView displays
(which supply power to the SkyView Network) can be damaged and require non-
warranty repair.
