PN 90488.2 SeaCAT/Sealogger RS-232 & Navigation Interface Box

Interface Boxes

Navigation (NMEA) interface, power, and other features for use with a variety of Sea-Bird instruments.

Sea-Bird manufactures several types of Interface Box, designed for use with specific products and for specific applications. Depending on application, an Interface Box includes a combination of the following functions:

  • RS-232 to RS-232 junction.
  • Optical-isolation — protects the CTD from electrical noise and possible accelerated corrosion caused by ground loop current. This may be necessary for applications where real-time data is transmitted to the ship or the instrument is powered from the ship. Some Sea-Bird instruments (such as the SBE 25) include internal opto-isolation, and therefore do not require an Interface Box for optical isolation.
  • NMEA Interface — interfaces with a navigation system to append latitude, longitude, and time data to the CTD data stream.
  • Remote Temperature Interface — interfaces with a remote temperature sensor to append remote temperature data to the CTD data stream.
  • AC to DC Power — converts AC power to DC power appropriate for the instrument.
  • DC to DC Power — converts DC power to DC power appropriate for the instrument.

All of our interface boxes have a five-year limited warranty.
