Servo Electrical Installation
Dynon Avionics’ servos are supplied with 7 unterminated wires, each about 8” in length. We
recommended that you use the SV-NET-SERVO (one per servo) network cabling kit when
installing servos; however, it is ultimately the responsibility of the installer to decide on
connectors and associated wiring.
Table 74 describes servo wire colors, and pins for DB9 connectors supplied in the SV-NET-
SERVO Kit.

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
