Online systems
Most Nortek products can be used either in stand-alone or online mode. In stand-alone mode, data are collected to the internal recorder, and the power comes from internal or external batteries. For online system, data is transmitted to shore in such a way that the measurements are continuously available.
There are many types of online data collection but all share two fundamental characteristics:
- The data must be transferred to shore
- The instrument must have power in order to operate
There are several ways to transfer the data to shore. Conceptually, a cabled connection is simplest and Nortek has spent a significant effort to ensure that the cabled systems are both functional and reliable. The practical elements that are required for a cabled system are described here.
