ECHOTRAC E20 Software update 5
After releasing the Teledyne Odom ECHOTRAC E20 we have continued to develop new features and options based on feedback from our users.
With the fifth update, the Teledyne Odom E20 now offers some exciting new features.
New Features
Updating Transducer Models
Mechanism to upload new transducers models to the E20. This mitigates the requirement for updated software releases. Users who now receive a new transducer models file from Teledyne can update in the SBES UI at Settings/Update. Previously updated transducers are shown in the About menu.
Save/Load SBES Settings
Users can save/load the SBES settings to/from a config file. The SBES settings include for example the selected transducer model, input/output settings, draft and index, units and more.This new functionality allows users to clone the E20 settings on another unit, or ensure that the same settings are used in between vessel mobilisations.
Heading Input
Heading string input. Users can now add a NMEA HDT string to COM1 (originally only NMEA GGA). The data are parsed to record 1013 for .s7k file recording. COM1 can now be used for Position and/or Heading and the sensor type is now referred to as ‘Navigation’. Real-time data (position, heading , or both) are displayed in the sensor data box.This now allows users to log data to .s7k file and use later for processing. Previously, this was only practical if the GNSS antenna is mounted directly on top of the transducer (ie heading not required).
In addition, users can now use the E20 as a pass-through to receive all survey data in their acquisition software as 7k records.
High Frequency Gating
High Frequency Gating option (HFG) allows users to track a sub-bottom layer with the Low Frequency channel. HF detections act as a gate for LF channel. In practice this means that the soft upper layer is detected by the HF and ignored by the LF, which instead detects the next strongest return. When HFG is used in combination with gates, the upper gate limit is set by the HF detection. No change in data output or data records. HFG is enabled/disable from a new button tin the top ribbon.
Info box for real-time and replay
An info box shows the current SBES settings. The (floating) info box is available both in real-time and replay mode.
Output formats
- Added NMEA DBT support
- Improved DESO25 support to allow for Dual Channel use
- Improved NMEA DBS, DBT to allow for HF/LF indication through talker ID
- Always output 2nd channel if in use
