The Locator-S1 carries an internal GPS based time sync module. Because of this, the S1 does not require tether integration for top-side communication. It only requires external power 10-18V to be provided from the underwater device.
Some Locator-S1 attributes can be configured using an integrated UART interface. This configuration is optional and not required for normal operation. Before deployment in water, the Locator-S1 needs to achieve a GPS lock. The integrated status-LED shows the condition of the GPS lock. Once the Locator-S1 has lock it can operate for approximately 6 hours befor needing resync with GPS.
The default channel for Locator-S1 is 17 on boot.
As the Locator-S1 does not carry its own depth sensor, the depth needs to be provided from the underwater vehicle (ROV etc.) to the topside Master-D1 using the software API. Example of how to perform this can be found here.
Flashing green light (fast): Searching for GPS lock. The unit is not ready to dive.
Fixed green light: GPS lock is acheived. The unit is ready to dive.
Flashing green light (slow): GPS lock has been acheived but lost. The unit is ready to dive.
No green light: Power is off and the unit is not ready for diving.
GPS based sync removes all tether requirements enabling very easy integration with any ROV.
Extremely small size making it perfect for even the smallest underwater vehicles.
Highly robust operation in areas with reflections (shallow water, around installations etc.)
The tables below shows the pinning of the S1 interface.
The Locator-S1 has a simple UART interface which is used to change the channel of the locator.
