Data Logging

The Rayfin logs NMEA data, with a time-stamp, from internal and external sensors. 

• Compatible NMEA sensors include GPS, system clocks, depth, altimeter, gyro, CTD, and others

• Topside NMEA data (GPS) can be sent to the camera via Serial or Ethernet via TCP or UDP port: 8889. See more info here: Data Input and EXIF

• Subsea NMEA sensors can be connected via RS-485 on Aux0 and Aux1.
  See more info here: Auxiliary Ports

• The data is time-stamped and stored in a CSV file in the “Data” folder on the camera. A new CSV file is created for each day. See more info here: Data Logging Controls

• Rayfin cameras contain an internal IMU. It displays and logs Tilt and Roll. 

• Some models of Rayfin include a Depth sensor. The depth is displayed and logged. The water temperature is also logged.

• An Altimeter can be connected to the camera Aux port. It will log and show altitude on the camera UI.
