There are two possibilities for integrating other sensors with the TR-ORCA. The user can use a spare input channel to sample analog information from another sensor, or a digital stream can be captured from an external sensor. Care must be taken to not exceed maximum input levels when using hydrophone channels for external analog information. At this time, the TR-ORCA does not support capturing a digital stream from an outside instrument, though this is planned for a future firmware release. Please contact us about any custom sensor integration requirements.
