<strong>Dynon</strong> ADAHRS/EMS/SYSTEM/NMEA Data OutputsTo output real-time data to an external serial device for recording:SV-D700 / SV-D1000 Installation and Configuration1. Wire a serial transmit line from one display to the receive line on the external serialdevice.2. Ensure there is a shared ground between the D700/D1000 and the external serialdevice.3. Configure the serial port on the display appropriately under SETUP MENU > LOCALDISPLAY SETUP > SERIAL PORT SETUP, selecting the desired output data format.USB Usage and AccessibilityIt is useful to have the USB socket on the display’s wire harness accessible afterinstallation for file uploads and downloads.The USB connector is used during the following operations:System firmware updatesConfiguration file uploads and downloadsDatabase updatesExternal Dim Control ConnectionUsers may control the backlight level on a <strong>SkyView</strong> display using a compatible external controlsignal. The external dim input on pin 25 on the display’s DB37 is compatible with a 0 to 36 voltDC control signal.The external dim output on pin 26 is an open-collector PWM output. This output is currently notsupported. A future firmware update will enable this capability.Audio Output ConnectionsAudio outputs are currently not supported in <strong>SkyView</strong> and the information in this section ispreliminary. A future firmware update will enable this capability. As of this firmware release, DONOT connect anything to the audio output connections.<strong>SkyView</strong> audio outputs on pins 13 and 31 (left and right, respectively) of the display’s DB37connector can drive headphones or audio panel inputs. Use left and right audio outputs forstereo mode. Left and right audio outputs should be electrically shorted together for monomode. Note that a ground connection between equipment is necessary also (audio ground ispin 30 on the DB37).If there is more than one display on a <strong>SkyView</strong> network and you want to connect the displays’audio outputs to the same headphone jack or audio panel input for redundancy, electricallyshort the respective left and right outputs together for stereo mode (i.e., left-to-left and rightto-right)or connect all audio outputs together for mono mode. The same rule applies for audiogrounds.<strong>SkyView</strong> System Installation Guide - Revision J 4-15
