SkyView System Installation Guide - Dynon Avionics

Internal Time KeepingSV-D700 / SV-D1000 Installation and ConfigurationZulu/GMT time is initially obtained from a GPS source. Time is displayed as “--:--:--“until a GPSfix containing time is found. When a display is turned off, a connected SV-BAT-320 enables thedisplay to keep track of time. Displays that are not connected to a battery must obtain currenttime from a GPS source whenever they are turned on.Serial DevicesSerial communication to non-Dynon devices and interfacing of other devices in general can beinvolved and detailed. This installation guide is intended to provide general installation advicefor the most common devices and situations. Dynon’s Documentation Wiki provides enhanced,extended, frequently updated online documentation contributed by Dynon employees andcustomers at wiki.dynonavionics.com.There are five general purpose RS-232 serial ports available for use with compatible equipmenton a SkyView display. Serial port transmit (TX) and receive (RX) wire sets are twisted togetherand connected serial devices must share a common power ground with the SkyView display(s).Dynon Avionics devices that use RS-232 serial ports for communication include the SV-GPS-250,SV-XPNDR-261 and-262, and SV-ADSB-470. Devices from other manufacturers that arecommonly used with SkyView include transponders (with serial port inputs), NAV radios such asGarmin SL30, COM radios such as Garmin SL40, GPS devices such as the Garmin X96 series,Vertical Power VP-X, and Emergency Location Transmitters (ELTs). Reference the appropriatesections of this manual for detailed instructions for installing the SV-GPS-250, SV-XPNDR-261and -262, SV-ADSB-470, and Vertical Power VP-X. Additionally, an external serial device such asa PC or external serial data logger can be connected and used to record real-time ADAHRS andEMS data that can be output by SkyView.Serial port 5 is recommended for the SV-GPS-250 connection. Its wire bundleincludes serial transmit, receive, ground, and power, and its wires are colormatchedto the wire colors on the SV-GPS-250.Transponders with serial altitude input can be directly connected to a display. To interface aSkyView display to a gray code transponder, the use of a Dynon Encoder Serial-to-Gray CodeConverter Module (Dynon P/N 100362-000) is required. Reference the Encoder Serial-to-GrayCode Converter Installation and Configuration Section of this guide for more information.If you have more than one SkyView display, each external serial device’s serial TX wire needs tobe connected to each screen so that it can send information to each display individually.Information that is received via serial connection is not automatically shared between multipleSkyView displays in an aircraft. Additionally, if the serial device you are connecting to yourSkyView system can receive information from SkyView, that device’s RX wire must beconnected to all SkyView displays as well. SkyView has special hardware to allow multiple TXlines to be connected together for redundancy. It is required that all connections to/from aparticular serial device be connected to the same SkyView display serial port on every display inthe SkyView system.SkyView System Installation Guide - Revision O 4-11
