Maximum Number Of Sounders
What is the maximum number of sounders allowed on a NN3D, TZT, TZT2, or TZT3 network.
You can have a maximum of two sounder sources. For the TZT, TZT2, and TZT3 systems you can also have the DFF3D multi-beam "Sonar" if desired. The TZT2 and TZT3 MFDs offer internal sounders. While these are available, the system supports a maximum use of two sounder sources regardless if using internal or external units. If you use an internal sounder, it will count towards the maximum number of sounders you can have in-use with the system.
