NIP
The Nortek Internal Processor (NIP) is a micro computer located inside the AWAC. Its primary function is to reduce raw wave data to standard wave estimates for online applications. The data aids in the use of low bandwidth /payload communications such as acoustic modems and satelites communication. The NIP data output is also well suited for integration with data loggers.
Reduction of wave data is valuable when considering low bandwidth communications (e.g. acoustic modems, satalite). The NIP is also essential for online systems that utilize data loggers, as the NIP permits user configurable ASCII formats.
The NIP is easily configured with the NIPtalk software or the online software SeaState. Data output may be as detailed as full spectral information or simple as basic wave estimates; the output format is either binary or user defined ASCII strings.
Since the NIP spends most of its time in sleep state, there is minimal power consumption. For standard AWAC configurations the NIP consumes approximately 10% of the AWAC's estimated power consumption.
