Page 7: Introduction
1. Introduction Overview The Super Seaking V7 series is built on a new platform, introducing an improved front end design, Ethernet connectivity and software power isolation for AUX port output. We have incorporated state of the art sensors to gather precision Sound Velocity and Density profiles for accurate depth and height data. -

Page 10: Installations
2. Installations Hardware Installation Mount the Seaking 700 using 3mm insulating rubber, and jubilee clamps to firmly secure to the vehicle. For accurate pressure measurement, the Seaking 700 Bathymetric sensor can be orientated in a port up or port down configuration with calibrated offsets provided by the factory. It’s recommended, during installation, that the bathy and altimeter be positioned so they receive good water flow while avoiding prop-wash from thrusters. -
Page 11: Powering The Bathy
Powering the Bathy The SeaKing 700 Series units are designed to work from a smoothed DC power supply. If using a rectified transformer PSU, the output of the PSU must have a filter capacitor of not less than 470μF, for each unit being powered. -
Page 12: Communications Configurations
Communications Configurations The V7 is a direct replacement for a V6 sonar with the exception of customers requiring Ethernet capability. This will require either a proprietary Tritech ‘V7 connector’ or a compatible connector and cable harness. Arcnet and Serial comms protocols are supported.. Seaking 700 Bathymetric sensors can be configured as Ethernet with Serial RS232/485 or as ARCNET and Serial RS232/485 communication protocols. -
Page 13: Wiring Diagrams
Wiring Diagrams The below wiring diagrams refer to the standard Tritech connector, other connector options are available upon request. Please contact our sales team for full details. WARNING Application of reverse supply voltage to the unit or supply voltage across any of the communication connections may lead to equipment damage not covered under the warranty conditions. -

Page 16: Windows Setup
Windows Setup Ethernet Protocol Settings The Ethernet adapter needs to be setup on the host PC to be in the same IP address range as the sensor being attached. Using network comms allows multiple sensors to be integrated using standard networking equipment. A minimum 100BASE−TX link is recommended. -

4. Device Configuration Window The device Configuration window is accessed from the node list by clicking on the drop-down (under the action column) and selecting setup. Below is an overview of the Configuration window. Head Info/Coeffs Tab- Information relating to Aux Altimeter Enabled- This setting notifies the the instrument build. -
Page 19: Seanet Pro Operation
Seanet Pro Operation The Following section covers basic operation within SeaNet Pro. The SeaKing 700 series can be operated alongside other devices in a multi-window application. For this example we will focus on the Single Bathy Application. Main Screen In the Applications menu at the top of the window, select “Single Bathy” to bring up the main Bathy interface screen. -

SeaNet Pro Tools Bathy Application Menu The Bathy application menu can be accessed either by clicking the menu icon in the top left of the top toolbar or by right clicking the mouse in the Bathy application window. Here you can access all settings and information screens for the bathy.

5. Optimising the SK700 V7 System Check The SeaKing 700 series heads should be checked for serviceability on the bench prior to undertaking any testing underwater. Before applying power to the unit ensure that it is in good physical condition with no damage to the sensors or housing. -
Page 24: Recommended Pre-Dive Checklist
Recommended Pre-Dive checklist The following is a suggestion list of items to be checked during a Pre-Dive procedure when using SeaKing 700 units. • The communications protocol for the Bathy is known and the topside control unit has been setup appropriately •... -
Page 25: Factors That Affect Measurement
Factors that affect measurement Water Density A bathymetric sensor measures seawater pressure. In order to calculate depth it must know the density throughout the water column from the surface to the operating depth. This value will change as the sensor moves through the water column, because varying temperatures and salinity will affect the overall density. - Page 26 Relative Measurements For relative measurements there is no requirement to zero the unit on deck because any error at the surface will represent a constant offset (gravity effects are also negligible). The important parameters are variations in atmospheric pressure, water column mean density and tidal corrections for the duration of the measurements.

Page 27: Care And Maintenance
6. Care and Maintenance Warning Opening of the unit will void the warranty. This unit is not designed to be field serviceable. Calibration and pressure certification will also become invalid should the unit be opened. After using the Super Seaking 700 We recommend that the unit be rinsed down with fresh water after each dive, especially if the unit is not intended to be used for an extended period. -
Page 28: Arcnet Termination
Appendix A A.1. ARCNET Termination Depending on the cable length the ARCNET communication link requires a termination resistor to be installed at each end of the umbilical cable. Normally this is supplied fitted within the ARCNET cable DA-15 or within the SCU/SeaHub at the surface and is left for the user to fit at the sub-sea end in a convenient junction box or by use of a special waterblock. -
Page 29: Depth Derivation
Appendix B B.1. Depth Derivation The Bathy V7 uses its ARM processor to carry out the various calculations required to derive depth, salinity, density, VOS, and altitude. This allows the V7 system to operate in a completely standalone mode, as opposed to the V3 system that requires the use of Seanet/Desktop PC to derive the above outputs. -
