Initial Parameter XML datagram
The Initial Parameter XML datagram contains information about all available virtual channels that may provide sample data in the file. This is an XML datagram. The type is XML0.
Format
These are the attributes in the <InitialParameter> tag. The attribute values are only included as examples.

Description
The Initial Parameter XML datagram is identified by the <InitialParameter> tag. The <InitialParameter> holds one <Channels> tag. The <Channels> holds one or more channels, identified by their ChannelID tag. The channels have common elements and elements specific to the type of channel or type of pulse form (CW or FM).
A WBT channel contain all of the above elements and no additional elements.
EC150–3C echo sounder channels have these additional elements.
•  Impedance
•  Phase
EC150–3C ADCP channels have these additional elements.
•  Impedance
•  Phase
•  MaximumVesselSpeed (not in use)
•  MaximumCurrentSpeed
•  DepthCellSize
If the PulseForm attribute is set to value 0 (zero) for CW, the FrequencyStart and FrequencyEnd attributes are replaced with a single attribute Frequency.
