Decoding Notes

The Driver will only properly decode the values if the checksum is correct. If checksum is invalid then the driver will not output any data!

The following formulas were used inside the driver to convert the values:

Heading = Value * 360 /1024

Depth Frequency = 750 * 65535 / (65535 – Value)

Depth in Feet = (Depth Frequency – 1000) * 1123 / 5000

Cp Voltage = (Value – 2048) * 2.5 / 2048

Quality Indicators

The status of the Compass is translated to a readable Quality Indicator:

The corresponding raw value is stored as the Quality indicator value for Depth and CP observations.

Depth is always converted to the current survey units.

Database Setup

  • Add a "Gyro" system, and select this driver. Select a COM port and setup communication parameters.
  • Add an "Underwater Sensor" system to decode the depth value from the message, and select the "Depth – SeaEye Boxer ROV" system. Select the same COM port as the Gyro system. 
    Select an ROV Depth Observation and the appropriate node set the unit to "Survey Unit".
  • Add a "Miscellaneous" system if the CP Value must be decoded too. Select the same COM port as the Gyro system. 
    Add an observation with a scale factor of 1.000 if you require the CP value in volts.

Choose for all these systems the same COM port, this way all systems will be supported by one driver program.
