Electrical Installation
SkyView Network
The SV-AP-PANEL has two SkyView Network connections (D9M connectors). Both connectors
are electrically identical and are internally connected. Thus, the SV-AP-PANEL can be installed in
the SkyView Network as a “pass-through” device, or “daisy chained” from one SkyView
Network device, through the SV-AP-PANEL, to the next SkyView Network device. The SV-NET-
1.5CC is an 18-inch SkyView Network cable that is ideal for such situations. The SV-AP-PANEL
receives power (for operation of the buttons) from SkyView Network. Dimming of the SV-AP-
PANEL is controlled by the SkyView display(s).
Trim Motor Control
In addition to the AP mode buttons, the SV-AP-PANEL includes an adjustable, speed-sensitive
trim controller, eliminating the need for relay packs or a separate trim controller. The
integrated trim controller is wired to a D15M connector that can be connected to Aircraft
power (12V only), pushbuttons (typically, on the stick), and power to and control of up to two
trim motors - such as those made by Ray Allen. A set of pushbuttons can optionally be installed
for the copilot. The pilot’s pushbuttons take priority over the copilot’s pushbuttons.
Pushbuttons used for Trim Motor Control must be Push Button Normally Open (PBNO) – a
momentary switch with a contact that is closed only when the button is pushed. One terminal
of the pushbutton is connected to the selected pin; the other terminal of the pushbutton is
connected to avionics ground (can be common with Pin 2).
Note that the SV-AP-PANEL’s trim controller only connects to the trim motors. The SV-AP-
PANEL does not connect to or monitor trim position. Monitoring trim position is done by
connecting the trim motor’s potentiometer (position sensor) that is mechanically ganged to the
trim motor to a General Purpose Input pin on the SkyView SV-EMS-220/221 as described in
