Serial Connection
SkyView uses the SV-GPS-250 device set to POS 1 as its primary position source.
The SV-GPS-250 includes 18 feet 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 color of the SV-GPS-250 wires matches the colors of the wires of the main display harness
that are intended for the GPS serial connection. The following table contains information
regarding the wires.
