Decoding Notes

The driver decodes multibeam, sidescan and miscellaneous data from the WASSP S3.
External sensor data is not decoded and external sensors (for instance position, motion and heading) should therefore be directly interfaced into Qinsy.



Discovering the system

In order to configure the system in Qinsy, the IP address of the WASSP S3 unit is required.
The easiest way to determine the unit's IP address is to use WASSP's 'find my DRX tool' which will show the IP address of any WASSP S3 unit on the network:

Note

The IP address of the WASSP is by default set using DHCP or ZeroConfiguration.
According to the DRX installation manual "If there is a DHCP server on the LAN, the DRX will be assigned an appropriate IP address by the DHCP server. If there is no DHCP server, the DRX will fall through to Zero configuration assignment in block 169.254.0.0/16".

We have noticed that on some occasions, the IP address of the unit changed after a connection loss.
In order to prevent this, we recommend to set the IP address to a static value. It is possible to do this through the unit's web interface.
The option to set the IP address can be found under SYSTEM→Network

The section 'Configuration of the WASSP S3' provides more information about the web interface.



Configuration of the WASSP S3

The WASSP S3 can be configured using the system's web interface. This interface can be reached by browsing to the IP address of the system on port 2001. For instance, if the IP address of the system is ------

The web interface allows the user to configure the external sensors that are interfaced to the system such as motion and PPS (Time Synchronization).
More information on how to set up external sensors for the WASSP S3 can be found in the 'DRX Installation Manual'.

Note

Although Qinsy only decodes the raw bathymetry, make sure to interface a motion sensor to the system.
The system will not output any bathymetry data if no motion sensor is interfaced.


Database Setup

This driver decodes the following systems:

  • Bathymetry from the 'Raw Bathy Data' message.
  • Sidescan from the 'Sidescan Data' message.
  • Miscellaneous observations:

    Source message message field description slot ID
    PPS Status PPS Frequency detected Approximate detected frequency of PPS signal in Hz. PPS_FREQ
    PPS Jitter ms Milliseconds of jitter detected between internal DRX time keeping and external PPS pulse. PPS_JITTER
    PPS Status 0 = Disabled
    1 = Untrained – no Time or PPS detected
    2 = Untrained – no Time detected
    3 = Untrained – no PPS detected
    4 = Training in progress
    5 = Synchronised – Poor (> 2ms jitter – occurs on initial sync)
    6 = Synchronised – OK (< 2ms jitter)
    7 = Synchronised – Good ( < 100us Jitter)
    8 = Synchronised – Excellent ( < 10us Jitter)
    9 = Synchronised – Perfect ( < 1us Jitter)
    PPS_STATUS
    PPS Timestamp A nanosecond time stamp of last active edge of PPS pulse received.
    This time is referenced at zero at 000hrs UTC time. This time may jump before synchronisation is achieved. No local time zone correction is applied. This time stamp will be free running if UTC time synchronisation is not available.
    PULSE_TIME
    Time Timestamp A nanosecond time stamp of last time sentence received.
    This time is referenced at zero at 000hrs UTC time. This time may jump before synchronisation is achieved. No local time zone correction is applied. This time stamp will be free running if UTC time synchronisation is not available.
    MSG_TIME
    Sonar Status System Temp Temperature of system in degrees Celsius SYS_TEMP
    Transducer Temp Temperature of the transducer sensor in degrees Celsius TD_TEMP
    Ping Rate Current ping rate in pings per second PING_RATE
    Transmission Centre Frequency Current transmitter center operating frequency in Hz CNTR_FREQ
    Transmission Bandwidth Current transmitter bandwidth in Hz BANDWIDTH
    Ping State Indicates current state of transceiver
    0 = None
    1 = Standard
    PING_STATE
    Sound Velocity Current sound velocity in meters per second SOUND_VELO
    Tide Value Current tide value in meters TIDE
    Link Speed Current Network Link Speed in Mb/s LINK_SPEED

Control

A number of parameters of the system can be changed online. In order to access these settings open the 'Control' tab of the multibeam system in the Echosounder Settings dialog.
If you have configured a sidescan system, but not a multibeam system, the settings can be found in the Control tab of the sidescan system instead:

Setting Description
Ping mode

Stop pinging: The system will not ping.

Auto pinging: The system will automatically ping.

Range mode

Auto range: The system will automatically detect the optimal ping range.

Manual range: The ping range can be set manually.

Manual range The range (in meters) to be used when the range mode is set to manual.
Power mode

No transmission: No pulse is transmitted (listen only).

Auto: The system automatically determines the optimal power level to use.

Manual: The power level is set manually.

Manual power The power level (in percent, 0-100) to be used when the power mode is set to manual.
