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.
