2. Introduction
2.1. Overview and Scope
The SeaTrac X100 series of Micro-USBL tracking and data modems are suite of complimentary
products built around a robust broadband spread spectrum signalling scheme. These multi-
purpose acoustic transponder beacons are capable of simultaneously tracking asset positions
and undertaking bi-directional data exchange, making them ideal for use in a wide range of
applications including…
 Remote monitoring and control of sensors and equipment,
 Re-location and retrieval of sub-sea assets,
 ROV positioning and navigation tasks,
 AUV navigation, telemetry, mission adjustments and real-time position monitoring,
 Diver buddy and surface-vessel/dive-bell tracking and re-location,
 Remote and local depth, water temperature, attitude and heading reference (AHRS)
information.
This document is intended to provide developers with the necessary information to allow
interfacing of SeaTrac Beacons with their systems using the serial communications port
hardware and command protocol, and intended to be read in addition to the hardware and
operational notes discussed in the specific Beacon’s user manual.
The subsequent sections of this document discuss the data types, constants and structures
commonly referenced by the serial command set, along with encoding schemes and a
complete reference for the serial messages accepted and generated by the beacon.
It is assumed that the reader has a reasonable level of programming expertise and is familiar
with the basic concepts of the serial port hardware within their chosen operating system, as
well as manipulation of numerical data types and basic software design principles.
