3. For thousands of years mankind has sailed the oceans. Only in the last century have we sailed beneath the surface. Undersea Warfare is an area of great technological growth. The US Navy operates a battery-powered large scale model submarine to study acoustic and hydrodynamic characteristics Presently a Charging technician to monitor and manually control the charge process at the individual chargers (7 Propulsion and 1 Instrumentation) The goal of this project is to develop a computer-controlled system to improve the efficiency of charging the batteries 3 Team Zap Gap - LSV2 Charger Remote Control

4. Utilize the existing chargers without modifying them directly Determine a reliable method of remotely articulating the functions of the chargers Design a Graphical User Interface to control and display charger output 4 Team Zap Gap - LSV2 Charger Remote Control

5. LSV2, USS Cutthroat, is a self-propelled fully autonomous research submarine. Bayview, ID on Lake Pend Oreille Test platform for hydro acoustic and hydrodynamic analysis 205 ton 10’ diameter 111’ length Represents Virginia Class Submarines Named in 1997 by Athol Elementary School for the indigenous Idaho fish. 5 Team Zap Gap - LSV2 Charger Remote Control

6. Interface via serial connection RS-232 ( also configurable for RS-485 protocol) Via a computer workstation Control of Chargers via a Graphical User Interface (GUI) Assembled using Windows Visual Studio 2008 Communication ports are configurable to those available at the PC MOXA CP-118EL Gives eight additional COMM ports to give each charger a dedicated signal path. Adds channel specific control for the user interface program 6 Team Zap Gap - LSV2 Charger Remote Control
