The Locator-A1 has the smallest physical footprint in our series of locators. It can be integrated into even the most compact ROVs. The Locator-A1 does not carry its own depth sensor, and the Master-D1 requires that the depth be provided from your underwater vehicle (ROV etc.) This can be achieved by means of the UGPS API.
The tables below shows the pinning of the A1 interface connectors.
