This output is activewhen the OBS annunciation is on the display.5.2.10.2 GPS ANNUNCIATE*The GPS ANNUNCIATE* output is driven when the unit is configured with a single CDI/HSI and theGPS data is being displayed on the CDI/HSI. This output parallels the GPS annunciation on the display.Pin Name Connector Pin I/OOBS ANNUNCIATE* P1001 14 OutGPS ANNUNCIATE* P1001 15 OutWAYPOINT ANNUNCIATE* P1001 33 OutTERMINAL ANNUNCIATE* P1001 34 OutTAWS AUDIO ACTIVE ANNUNCIATE* P1001 35 OutVLOC ANNUNCIATE* P1001 52 OutLOI ANNUNCIATE* P1001 53 OutMESSAGE ANNUNCIATE* P1001 54 OutAPPROACH ANNUNCIATE* P1001 55 OutILS/GPS APPROACH ANNUNCIATE* P1001 56 OutTAWS/TERRAIN INHIBIT ANNUNCIATE* P1001 57 OutTAWS WARNING ANNUNCIATE* P1001 71 OutTERRAIN NOT AVAILABLE ANNUNCIATE* P1001 72 OutTAWS CAUTION ANNUNCIATE* P1001 73 OutGPS SELECTANNUNCIATE* [1] P1001 74 OutTRAFFIC TEST ANNUNCIATE* P1001 75 OutTRAFFIC STANDBY/OPERATE ANNUNCIATE* P1001 76 OutSUSPEND ANNUNCIATE* P1002 3 OutGSR REMOTE POWER* P1002 12 OutRP MODE ANNUNCIATE* -- -- Out
