  • Page 4: Installing The Wbt Using The Integrated Brackets

    Installing the WBT using the integrated brackets The EA640 WBT is normally positioned in a dedicated room in the vicinity of the transducer. The physical length of the cables limit the physical distance between each transducer and the WBT. The WBT can be installed vertically or horizontally using the integrated mounting brackets.

  • Page 5: Installing The Wbt In A 19" Cabinet

    Prerequisites It is assumed that the WBT Cabinet has already been installed. Context If your EA640 comprises more than one WBT, you can use the optional WBT Cabinet. This 19" cabinet holds maximum seven WBTs with power supplies, as well as an Ethernet switch and a power distribution panel.

  • Page 6: Installing A Commercial Computer

    Note Make sure that the chosen computer meets the EA640 requirements. The design and construction must allow for marine use, and the computer must be able to withstand the movements and vibrations normally experienced on a vessel. Verify that you have easy access to cables and connectors, and that the computer can be installed in a safe and secure way.
  • Page 7 Installing the EA640 hardware units Depending on its physical properties, install the computer inside a console, in a cabinet or 19” rack, or on a desk. Choose a position to fit the available cable lengths between the computer and the other units it connects to.
