Garmin SL30, COM radios such as Garmin SL40, GPS devices such as the Garmin X96 series,
Vertical Power VP-X, and Emergency Location Transmitters (ELTs). Reference the appropriate
sections of this manual for detailed instructions for installing the SV-GPS-250, SV-XPNDR-261
and -262, SV-ADSB-470, and Vertical Power VP-X. Additionally, an external serial device such as
a PC or external serial data logger can be connected and used to record real-time ADAHRS and
EMS data that can be output by SkyView.
Serial port 5 is recommended for the SV-GPS-250 connection. Its wire bundle
includes serial transmit, receive, ground, and power, and its wires are color-
matched to the wire colors on the SV-GPS-250.
Transponders with serial altitude input can be directly connected to a display. To interface a
SkyView display to a gray code transponder, the use of a Dynon Encoder Serial-to-Gray Code
Converter Module (Dynon P/N 100362-000) is required. Reference the Encoder Serial-to-Gray
Code Converter Installation and Configuration Section of this guide for more information.
If you have more than one SkyView display, each external serial device’s serial TX wire needs to
be connected to each screen so that it can send information to each display individually.
Information that is received via serial connection is not automatically shared between multiple
SkyView displays in an aircraft. Additionally, if the serial device you are connecting to your
SkyView system can receive information from SkyView, that device’s RX wire must be
connected to all SkyView displays as well. SkyView has special hardware to allow multiple TX
lines to be connected together for redundancy. It is required that all connections to/from a
particular serial device be connected to the same SkyView display serial port on every display in
the SkyView system.
The instructions above specify that both the TX and RX lines from external serial
devices be connected to multiple screens in parallel. SkyView systems that were
installed before SkyView v2.6 may require wiring changes to accommodate this.
Specifically, if your system has multiple SkyView displays and your transponder is
utilizing the serial altitude encoder output, the transponder would have only been
connected to one screen when you configured your SkyView system. As of v2.6,
transponders (and other serial devices) must be connected to all SkyView displays
to work correctly.
It is the installer’s responsibility to determine how to connect external serial devices to the
display using the included wire harness. Installers should reference serial device documentation
for serial port specifications. The basic order for installing an external serial device is as follows.
1. Specify a serial port for the device.
2. Make the serial port electrical connection. If you have more than one SkyView display,
make the same connection to all SkyView displays.
3. Configure the serial port (under SETUP MENU > SYSTEM SETUP > SERIAL PORT SETUP)
according to the device’s documentation.
4. When serial port configuration is complete, perform a final check by doing the
following:
