Figure 9 – SkyView System with Two Redundant Displays, One EMS, Two Backup Batteries (One per Display),
Two Redundant GPS, Two Redundant ADAHRS, Two Servos, and one Transponder using a hub (recommended
installation method)
Note, that in Figure 9, each SV-GPS-250’s power, ground, and output wires are
connected to both displays on different serial ports. The primary SV-GPS-250
should be connected to serial port 5 on each display. The secondary SV-GPS-250
should be connected on another serial port on each display.
Additionally, if there are both multiple displays and multiple SV-GPS-250 units in
the system, power for the secondary GPS should be sourced from the GPS power
wire on the second display – in other words, each SV-GPS-250 should receive
power from a different display. Reference the SV-GPS-250 Installation and
Configuration Section for more information on this configuration.

software. Additionally, external GPS and NAV radio sources can be used as well. Reference the
