the wires listed in the table leave one end of the Encoder Converter in a single bundle. If your
transponder has a switched power output, connect this to the power inputs on the Encoder
Converter. If your transponder does not include this switched power output, the Encoder
Converter power connections should be made directly to your switched avionics power. Ensure
that all avionics power is off before performing the wiring step of this installation.
If your Altitude Transponder has either a strobe signal or a D4 pin, leave these pins
unconnected.

The Gray code output of the Encoder Converter reports altitude not adjusted for barometric
pressure, as required by FAA specification. The altitude reported by the SkyView encoder will
always match the altitude shown on screen when the BARO value is set to 29.92 inHg.
SV-D700 or SV-D1000 Connection
Before wiring connections to the SkyView display check to ensure that the wire length between
your Encoder Converter and your display is appropriate. Add or remove wire length if needed
or desired. Customizing the wire length will facilitate an installation that is both cleaner and
more secure.
If you have more than one SkyView display, note that like all other serial devices, the encoder
converter module needs to be connected to a serial TX from each display simultaneously. See
the Serial Devices section for more information about this requirement.
Any general purpose SkyView display serial port is compatible with the Encoder Converter
module. Connect the Encoder’s input (green or red) to an appropriate wire on the display
harness (reference the SV-D700 / SV-D1000 Electrical Installation Section for details on which
pins to use). Also ensure that the display and the Encoder Converter Module share a ground.
Figure 95 illustrates the basic electrical connection between the SkyView display and the
Encoder Converter module.
