SV-GPS-2020 GPS Antenna/Receiver Installation and Configuration
11-4 SkyView HDX System Installation Manual - Revision E
Mounting hardware is not included. The SV-GPS-2020 is designed to install with #8
fasteners with 100 degree countersunk heads. The use of nut plates is recommended for
convenience, but other hardware can be used if space allows. Specific hardware selection
is determined by the installer.
We recommend the use of weather sealant around the fastener heads to keep moisture
from entering the aircraft through the mounting holes. The module itself is sealed and
includes a rubber gasket that seals the inner wire hole. It also allows the module to be
mounted on slightly curved surfaces. For extra protection, you may use weather sealant
around the outside of the SV-GPS-2020 where it meets the skin of the aircraft.
11.3 Electrical Installation
For its primary source of GPS data, SkyView uses the GPS data from the
device set to SERIAL IN FUNCTION: POS 1.
If your installation has two (2) or more displays, all four (4) wires of the SV--
GPS-2020 must be connected to all displays.
The SV-GPS-2020 includes 18 feet (5.49 meters) of twisted wire for a serial connection
to the SkyView display via the display. This wire may be trimmed or lengthened as needed
to suit the installation – the length of these wires is not critical.
The color of the SV-GPS-2020 wires matches the colors of the wires of the SV-
HARNESS-D37 that are intended for the GPS serial connection. The following table
contains information regarding the wires.

As mentioned previously, if there are two (2) or more displays in your SkyView system,
all four (4) of the SV-GPS-2020’s wires must be connected to all displays in parallel. This
wiring scheme is illustrated in the figure below.
