HARDWARE VARIATIONS AND COMPATIBILITY
The 4125 Side Scan Sonar System contains both standard and proprietary hardware. At times, EdgeTech
may change the standard components due to their availability or performance improvements. Although
the component manufacturers—along with their models and styles—may change from unit to unit,
replacement parts will generally be interchangeable.
EdgeTech will make every effort to see that replacement components are interchangeable and use the
same software drivers (if applicable). At times, however, direct replacements may not exist. When this
happens, EdgeTech will provide the necessary drivers with the replacement part, if applicable.
EdgeTech may also change certain hardware per customer requirements. Therefore, portions of this
manual, such as parts lists and test features, are subject to change. These sections should be used for
reference only. When changes are made that affect system operation, they will be explicitly noted. Also,
some options and features may not be active in the customer’s unit at time of delivery. Upgrades will be
made available when these features are implemented.
Contact EDGETECH CUSTOMER SERVICE with any questions relating to compatibility.
