SV-GPS-250 Installation and Configuration
8-4 SkyView System Installation Guide - Revision S
If there is more than one SV-GPS-250 in your system, use the same scheme in Figure 56 on
different display serial ports for the other SV-GPS-250 modules, but connect power and ground
for the other SV-GPS-250 modules to the same power and ground connections (black and
orange wires) that are provided in the serial port 5 wiring bundle on the display harnesses. An
example of this configuration follows.

Configuration
Go to the Serial Port Setup Menu (SETUP MENU > SYSTEM SETUP > SERIAL PORT SETUP>SERIAL
PORT 5 SETUP) and then configure serial port 5 as follows:
SERIAL IN DEVICE: Dynon SV-GPS-250
SERIAL IN FUNCTION: POS 1
SERIAL IN/OUT BAUD RATE: 38400
SERIAL OUT DEVICE: NONE
If you have multiple SV-GPS-250 modules, connected as shown above, you must
configure the second serial port (serial port 4 if done as shown) as an SV-GPS-250
as well. Its SERIAL IN FUNCTION should be set to POS 2.
