Furuno DFF-3D Sounders with TZ Software Instruction Manual

Furuno DFF-3D Sounders with TZ Software

Specifications

• Product Name: Furuno Sounders with TZ Software
• Compatibility: Interfaceable with proper TZPro software licenses
• Functionality: PBG, BD, Hardness, Backscatter
• Requirements: Specific modules and transducers as detailed below

Personal Bathymetric Generator (PBG)
Personal Bathymetric Generator (PBG) enables you to record sea floor bathymetric information using a single beam or a multibeam echosounder. When using PBG, it creates a 3D representation that improves with repeated trips over the same areas. It allows for depth shading, custom contour lines, and more.

Requirements

• Requires TZPro PBG module
• Requires BOTH TZPro PBG and either DFF3D or WASSP module

Bottom Discrimination/Classification (BD)
Bottom Discrimination/Classification (BD) determines bottom structure categories like mud, sand, gravel, and rock. It can be networked to TZPro for display and analysis.

Furuno and TZPro Interface
PBG vs BD vs Hardness vs Backscatter

Summary – Various combinations of sounder and transducer combined with TZPro software are interfaceable together with the proper TZPro software licenses to attain added functionality and features to a system. This document helps to clarify those combinations in the effort to achieve one or more of the following desired results:

• PBG = Personal Bathymetric Generator
• BD = Bottom Discrimination/Classification
• Hardness = Bottom Hardness
• Backscatter = Bottom Backscatter
• *Specific transducers are required for BD from these sounders
• **Specific transducers are required for Hardness from these sounders
• ***WASSP also requires its own licensing of TZPro and Backscatter…PLUS the TZPro licensing above
• Please note that PBG data from TZ Pro is not the same as PBG from Furuno MFDs.

Explanation, comparisons, and pros/cons of each can be found in the following pages of this document.

Personal Bathymetric Generator

(PBG) enables you to record sea floor bathymetric information using a single beam or a multibeam echosounder. When you use PBG, it will create a 3D representation that will constantly improve with repeated trips over the same areas. In addition, the PBG module allows you to display depth shading (color according to depth), and custom contour lines.

REQUIREMENTS

• Single beam sounder that will output NMEA0183 depth (DBT or DPT).
  • Requires TZPro PBG module
• OR a multi-beam like a DFF3D or WASSP (wider area, higher resolution, faster mapping).
  • Requires BOTH a TZPro PBG & one of the following DFF3D modules (DFF-3D) or WASSP module (WASSP)

TZPro can also record Bottom Discrimination/Classification or Bottom Hardness or Backscatter information at the same time as the PBG depth and be able to display this information in various ways (see details below).

Bottom Discrimination/Classification

(BD) is from connecting Furuno Ethernet sounders that have a bottom classification feature that determines the bottom structure and separates them into the following categories: mud, sand, gravel, and rock. They can be directly networked to TZPro. See the Furuno website for acceptable BD transducers for each sounder.

REQUIREMENTS

• BBDS1, DFF1-UHD, TZT2, TZT3 with BD approved Dual frequency transducer (compares L vs H)
  • Requires TZPro Furuno Sounder module

• TZPro can also map this BD in a type of Bottom Hardness. Customizable color palette for depth and hardness shading.
  • Requires TZPro Furuno Sounder module and the PBG module.

Bottom Hardness –Is from Furuno sounders that have a hardness feature that determines the bottom change in hardness using reflectivity of a single frequency transducer. FCV295 and FCV1150 can be interfaced via serial NMEA0183

REQUIREMENTS

• FCV295, FCV1150 must select a transducer from the list in the set-up page (no manual transducer set-up allowed)
  • TZ requires both the PBG Module and Bottom hardness module (is a serial NMEA0183 connection)

(295 and 1150)
Can choose and calibrate colors| Display modes LF/HF/DF alter hardness (295 and 1150)

• It is important to note that though Hardness and Backscatter are often interchangeable terms…TZPro scales and stores these two types of data differently and separately. They cannot be combined.

Backscatter – Is from a WASSP Multibeam that determines the bottom change in hardness using reflectivity of a single frequency transducer. WASSP can be directly networked and controlled through TZPro. The closest comparison to the WASSP interface is the DFF3D (which does not produce backscatter charts).

NOTE – that TZPro does not allow the simultaneous interface with a WASSP and a DFF3D system.
NOTE – DFF3D PBG is not transferable between the Furuno MFD (TZT3) and TZPro

REQUIREMENTS

• WASSP is the best choice to give the customer affordable high level multibeam functionality
  • TZ requires both the WASSP module and PBG Module (is a network connection)
  • WASSP requires both the TZPro output license and the Backscatter license

multibeam (1.5m PBG)
