you should try to find ways to reduce the vibration. Read more about this in the Mounting Guideline.
For Vectors, there is an option to add an IMU to know more about how movement of the instrument
affects the measurements.
5.3.9 Error and Status Codes (Vector)
The Vector output two multiple bit binary coded words describing the instrument state. The following
explains the meaning of each bit in the Error and Status words. The bits within the words count from
right to left starting with zero.
Error word:
The bit is set ("1") if there is an error condition and cleared ("0") if ok.
Bit 7 - Coordinate transformation: If the compass fails and the system is set to ENU the system will
output XYZ and this bit will be set.
Bit 6 - Sensor: Vector: The tilt sensor is not responding.
Bit 5 - Beam number: A problem has occured with the beam order.
Bit 4 - Flash: An error has occured in the primary system flash memory and the system may not be
able to reboot.
Bit 3 - Tag bit: There has been an error in the processing, an internal buffer is overflowing.
Bit 2 - Sensor data: One of the sensors is not operating correctly.
Bit 1 - Measurement data: An error has occured with some element of the processing, the data is
probably corrupted.
Bit 0 - Compass: The compass does not respond. If the system is in ENU mode it will default to
XYZ, and a value of 90 degrees will be displayed.
Status word:
Bits 7 and 6 - Power level: These bits reflect the power level setting, i.e. how much acoustic energy
the instrument transmits into the water. This is set by the user in the deployment planning dialog
when configuring the instrument.
Bit 7 Bit 6 Power level
0 0 High
0 1 High -
1 0 Low +
1 1 Low
Bits 5 and 4 - Wakeup state: These bits indicate the wakeup state of the instrument. There are four
different ways that can cause a wakeup of the instrument and hence there are two bits in the status
field that identify the wakeup source.
Bit 5 Bit 4 Wakeup state
0 0 Bad power
0 1 Power supplied
1 0 Break
1 1 Real Time Clock (RTC)
Bad power status is used when the input voltage to the instrument during normal operation is so
low that the instrument may no longer operate correctly. The hardware is then held in a reset state
until the voltage reaches an acceptable level. It is typically caused by a broken cable or a faulty
power supply.
Power supplied is the status code when power is applied to an instrument. To get this status code
the power must typically be removed for a few seconds. Removing power for just one second will
typically be indicated as bad power.
Break status indicates an instrument reset because a break was received on the communications
port. The break is used when the software communicates with the instrument. This will typically be
status code in the first data record in an online measurement.
Real Time Clock status shows that the internal clock in the instrument caused the wakeup. To
reduce the power consumption the instruments enters sleep mode between measurements for
most setups. The internal RTC will ensure that the instrument wakes up at the appropriate time
