3.11 ADS-B In Considerations
The GTX 345 provides ADS-B In data regardless of the state of the transponder. HSDB ADS-B In displays cannot
connect to more than one ADS-B In source. If a GTX 345 is in a system that contains a GDL 88, ADS-B In must be
disabled in the GTX 345. In dual GTX 345 installations that connect through HSDB, one GTX 345 must have ADS-B In
disabled.
