SkyView HDX Display Installation and Configuration

installing the SV-GPS-2020, SV-XPNDR-261, SV-ADSB-472, 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-2020 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-2020.
If you have more than one (1) 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.
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 (1) 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 the serial port configuration is complete, perform a final check by doing the
following:
a. Power down all displays except #1. Verify all serial port devices are working -
transponder, GPS, radios, etc.
b. Power down all displays except #2. Verify all serial port devices are working -
transponder, GPS, radios, etc.
c. Power down all displays except #3. Verify all serial port devices are working -
transponder, GPS, radios, etc.
A SkyView Display serial port can be configured to communicate with one (1)
device on its TX and a different device on its RX, but when doing so, the TX
and RX speeds must be the same.
