Data subscription type: Integration
The integration data subscription string is Integration.
The update of Sa will be enabled by setting the Integration State to start. If the update parameter is set to Update Ping, the new Sa value is received for every ping. If the Update Accumulate is set, the Sa is received only when the Integration State changes to Stop.
Input
•  Type = The variant type as defined for certain programming languages
–  VT_BSTR = Text string
–  V_R8 = double, 8 bytes
–  VT_I4 = Integer 4 bytes
•  R/O = Read only
•  N/A = not applicable
•  If no value is provided in the XML input string, the example value in each table is used as default.
LayerType
Description Range Unit Type R/O
This is the current layer type. Surface
Bottom
Pelagic
  VT_BSTR N/A
Example: Surface
IntegrationState
Description Range Unit Type R/O
This is the "on/off" switch for the integration. Start
Stop
  VT_BSTR N/A
Example: Start
Pulse form
Description Range Unit Type R/O
This option is used for pulse form. The different types of pulse forms will be induce different calculations of integration CW Chirp   VT_BSTR N/A
Example: CW
Update
Description Range Unit Type R/O
This is a "selector" that allows you to provide integration value for latest ping or for the calculation interval. UpdatePing
UpdateAccumulate
  VT_BSTR N/A
Example: UpdatePing
Range
Description Range Unit Type R/O
If the depth range is selected to be individual for each channel, this parameter sets the range for specified channel. <0,10000> m VT_I4 N/A
Example: 500
RangeStart
Description Range Unit Type R/O
This is the start range for the selected channel. <0,10000> m VT_I4 N/A
Example: 10
Margin
Description Range Unit Type R/O
This is a range selector. Use it to set the range over the detected bottom. This range will not be included in integration. <0,200> m VT_I4 N/A
Example: 1
SvThreshold
Description Range Unit Type R/O
This is a threshold selector. Set this threshold to remove the weakest echoes from the integration. <-200,100> dB VT_R8 N/A
Example: -100
