Parameter XML datagram
The Parameter XML datagram contains information about parameters that may change from one transmission ("ping") to the next, for a specific channel. This is an XML datagram. The type is XML0.
Format
These are the attributes in the <Parameter> tag. The attribute values are only included as examples.
<Parameter>
  <Channel
  ChannelID="WBT 545603-15 ES120-7C"
  ChannelMode="0"
  PulseForm="1"
  FrequencyStart="95000"
  FrequencyEnd="160000"
  PulseDuration=”0.002048”
  SampleInterval="1.06666666666667E-05"
  TransmitPower="250"

</Parameter>
Description
The Parameter XML datagram is identified by the <Parameter> tag. The <Parameter> tags can hold one or more <Channel> tags.
A WBT channel contain all of the above elements and no additional elements.
Echo sounders have two additional elements Impedance and Phase.
•  Impedance
•  Phase
EC150–3C ADCP channels have these additional elements.
•  Impedance
•  Phase
•  EpochTime: sensor timetag
•  MaximumVesselSpeed: 0.0 .. 10.0 m/s
•  MaximumCurrentSpeed: 0.0 .. 10.0 m/s
•  DepthCellSize: |1|2|4|8| m
If the PulseForm attribute is set to value 0 (zero) for CW, the FrequencyStart and FrequencyEnd attributes are replaced with a single attribute Frequency.
