Linking all P4 (N2K) devices to a N2K network, there are three sub-menus:
Advanced (Advanced AP Inst Group)
Allows the user to configure specific devices on the network.
For most devices the only options will be “Set PGN Update Rates” and “Device Info”
The first option will retrieve a list of PCNs’ emitted by that device and allow a user
to request changes to the rate of emittance of a given PGN through a menu.
The second option will display some basic information on the device, such as the
Model ID, Serial, and Software Version
For some proprietary ComNav devices, the options “Compass Constants”, “Cal.
Compass”, “Compass Settings”, “Compass Attitude Biases”, and “0183 Port Configuration”
will also appear. These allow for advanced configuration of those devices.
