SkyView System Installation Guide - Dynon Avionics

SV-D700 / SV-D1000 Installation and ConfigurationThe instructions above specify that both the TX and RX lines from external serialdevices be connected to multiple screens in parallel. SkyView systems that wereinstalled before SkyView v2.6 may require wiring changes to accommodate this.Specifically, if your system has multiple SkyView displays and your transponder isutilizing the serial altitude encoder output, the transponder would have only beenconnected to one screen when you configured your SkyView system. As of v2.6,transponders (and other serial devices) must be connected to all SkyView displaysto work correctly.It is the installer’s responsibility to determine how to connect external serial devices to thedisplay using the included wire harness. Installers should reference serial device documentationfor serial port specifications. The basic order for installing an external serial device is as follows.1. Specify a serial port for the device.2. Make the serial port electrical connection. If you have multiple SkyView displays, eachserial port transmit and/or receive wire to or from a serial device must be connected toeach display in parallel.3. Configure the serial port (under SETUP MENU > SYSTEM SETUP > SERIAL PORT SETUP)according to the device’s documentation.4. When serial port configuration is complete, perform a final check by doing thefollowing:a. Power down all displays except #1. Verify all serial port devices are working -transponder, GPS, radios, etc.b. Power down all display except #2. Verify all serial port devices are working -transponder, GPS, radios, etc.c. Continue for additional displays if installed.A SkyView Display serial port can be configured to communicate with one deviceon its TX and a different device on its RX, but when doing so, the TX and RX speedsmust be the same.Table 10 contains serial port wire functions and wire harness colors.Serial Port Wire FunctionSkyView Display HarnessWire Colors1TX Brown with Orange stripeRX Brown with Violet stripe2TX Yellow with Orange stripeRX Yellow with Violet stripe3TX Green with Orange stripeRXGreen with Violet stripe4TXBlue with Orange stripeRXBlue with Violet stripe5 TX Gray with Orange stripe4-12 SkyView System Installation Guide - Revision O
