Appendix A: Maintenance and TroubleshootingNetwork Configuration Does Not Work or SkyView Network Module Is Not WorkingProperlyIf you try and configure a SkyView network and it does not work, try the following:Check network wiring and try again. There may be a short or an open somewhere.Unplug network modules one by one and try again. It is possible that one of themodules could cause the network to stop functioning.Try again.For modules such as the SV-ADAHRS-20X, the SV-EMS-220/221, and SV-ARINC-429,observe the red LED light near the SkyView Network connector:o Flashing Fast: The module is operating normally and is configured andcommunicating on a SkyView Network.o Flashing Slowly: The module is operating normally, but is not active on SkyViewNetwork.o Off: The module is not receiving power (from a SkyView Network / Display)o On Solid - the module is receiving power, but is not operating normally.SkyView Reports STANDBY NETWORK ERRORSkyView has detected a problem with the SkyView Network wiring between one or moremodules. Go to SETUP MENU > SYSTEM SETUP > NETWORK SETUP > NETWORK STATUS for adescription of the problem. Module failures and/or wiring faults (via SkyView D9 connector pincallouts) will be annunciated here to aid troubleshooting. The fault will be below thecomponent(s) that SkyView can see the fault in. This may help you narrow down the wiring runor connector that is faulty.For example, a “Connection Fault: 4/8” listed below an SV-ADAHRS-200 listing in the networkstatus page means that pins 4 and 8 on a SkyView Network harness or connector that goes tothat component has a connectivity problem. This could be a broken wire, swapped wires, badconnection, etc, and should be analyzed with a multimeter or other direct method.If the fault were instead listed under a SkyView display listing in the network status page, thatmeans that the fault is seen on devices connected to that display, and is likely due to aconnectivity issue at or very near the display in your SkyView Network wiring scheme.Compass Calibration FailsIf you try to calibrate your compass and it does not work, try the following:Ensure SkyView is receiving data from the system’s GPS receiver. Go to the DisplayHardware Information Page as mentioned at the beginning of this section, scroll downthe menu to the serial port status section, and confirm that the receive (RX) counter isactive on the GPS serial port.Ensure the SkyView network status includes the ADAHRS you’re trying to calibrate. Usethe Network Status Wizard and confirm that the ADAHRS is present in the system.Ensure the ADAHRS location is compatible with the requirements outlined in theGeneral System Installation Tips Section of this guide.SkyView System Installation Guide - Revision O 17-9
