Serial Data Connection
For its primary source of GPS data, SkyView uses the GPS data from the device set
to SERIAL IN FUNCTION: POS 1.
If your installation has two or more displays, all four wires of the SV-GPS-250
and/or SV-GPS-2020 must be connected to all displays.
The SV-GPS-250/2020 includes 18 feet (5.49 meters) of twisted wire for a serial connection to
the SkyView display via the display. This wire may be trimmed or lengthened as needed to suit
the installation – the length of these wires is not critical.
The color of the SV-GPS-250/2020 wires matches the colors of the wires of the SV-HARNESS-
D37 that are intended for the GPS serial connection. The following table contains information
regarding the wires.
