Puck
Instrument
Monterey Bay Aquarium Research Institute (MBARI) developed the Programmable Underwater Connector with Knowledge (PUCK). The MBARI PUCK (Figure 8.36) has the advantages of being a simple, small storage device for instrument-related information (e.g., unique ID, instrument driver, other metadata). Instrument information is automatically retrieved by the host computer when the PUCK and instrument are plugged into the host.
Integral data converters
Solid-state convertor electronics are pressure tolerant and can be built into a connector or a splice. The convertor transitions electric to optical, serial to Ethernet, or RS-232 to RS-485.
Connectorless data transfer
Data noncontact connections include:
• Inductively Coupled Modem
• BlueTooth (Wi-Fi)
• Optical Infrared (IR)
