Back in May 2018, Sea-Bird Scientific upgraded the SeaFET™ pH sensor to the “SeaFET™ V2”, improving upon the performance of the original SeaFET™ while retaining the same underlying ISFET sensor technology. The SeaFET™ V2 improves upon the original SeaFET’s reliability, data quality, ease of operation, and deployment endurance. Among these changes, the SeaFET™ V2 has a completely restructured RS-232 interface. This has a few implications for communicating with the SeaFET™ V2/SeapHOx V2/Deep SeapHOx V2:
- The Sea-Bird Scientific UCI 2.0 software (also compatible with the SUNA V2 and HydroCAT-EP) is now the primary software interface. UCI looks and behaves similarly to SeaFETCOM and retains the same ability to configure the SeaFET™ V2 and upload/process data. SeaFETCOM is not compatible with the SeaFET™ V2.
- The SeaFET™ V2 has a completely revised command set that includes commands common to other Sea-Bird Scientific CTDs. The original SeaFET™ V1 commands are no longer valid for the SeaFET™ V2.
- The SeaFET™ V2 no longer utilizes Burst Sampling and Sample Averaging. Instead, autonomous and polled sampling routines are identical to standard Sea-Bird moored CTDs.
- The SeaFET™ V2 data output is more consistent with Sea-Bird Scientific CTDs. Due to differences between the V2 and V1 output, any system configured to accept the SeaFET V1 output must be reconfigured for the new V2 output.
