Bit 11 xxxxxxxxxxxxxxxxxxxx1xxxxxxxxxxx High standard deviation tilt
Bit 12 xxxxxxxxxxxxxxxxxxx1xxxxxxxxxxxx Higher standard deviation tilt
Bit 11,12 xxxxxxxxxxxxxxxxxxx11xxxxxxxxxxx Even higher standard deviation tilt
Bit 13 xxxxxxxxxxxxxxxxxx1xxxxxxxxxxxxx Low input voltage, set if voltage below 6V

Bit 15 xxxxxxxxxxxxxxxx1xxxxxxxxxxxxxxx High input current, set if current above 300mA
Bit 16 xxxxxxxxxxxxxxx1xxxxxxxxxxxxxxxx Low Vtx1 voltage detected, set if Vtx1 below 4.8V
Bit 17 xxxxxxxxxxxxxx1xxxxxxxxxxxxxxxxx Low Vtx2 voltage detected, set if Vtx2 below 4.8V
Bit 18 xxxxxxxxxxxxx1xxxxxxxxxxxxxxxxxx Low heap memory detected
Bit 19 xxxxxxxxxxxx1xxxxxxxxxxxxxxxxxxx Sensor is in air, set when in air if air detection is active
Bit 20 xxxxxxxxxxx1xxxxxxxxxxxxxxxxxxxx Upside down surface mismatch reference mismatch
Bit 21 xxxxxxxxxx1xxxxxxxxxxxxxxxxxxxxx Upside down surface cell mismatch
The upside down selection does not correspond to the actual orientation detected by the sensor.
1)
The sensor measures the signal level on Beam 1 before pinging. This can indicate that another acoustic transmitter is
2)
sending out a sound signal nearby in the water (for example an echo sounder on a boat/ship). The noise level on
Beam1 is indicated by two bits, bit 1 and 2, which gives three level indications. If bit1 is set, the noise is above –48dB. If
bit 2 is set the level is above –38dB and if both are set the level is above –28dB.
Same levels as for Beam1 but here bit 3 and 4 indicates the three noise levels.
3)
Same levels as for Beam1,2 but here bit 5 and 6 indicates the three noise levels.
4)
Same levels as for Beam1,2,3 but here bit 7 and 8 indicates the three noise levels.
5)
Bit 9 and 10 indicates if the standard deviation for heading is above limit 1, limit 2 or limit 3. Limit 1 is 10°, limit 2 is 20°
6)
and limit 3 is 30° standard deviation on heading.
Bit 11 and 12 indicates if the standard deviation for tilt is above limit 1, limit 2 or limit 3. Limit 1 is 10°, limit 2 is 20° and
7)
limit 3 is 30° standard deviation on absolute tilt.
The internal software allocates memory for variables and objects. Software bugs may cause memory leakage which
8)
again gives less and less room on the heap.
Factory enabled setting to detect if the sensor is in air (only used with 5400 and 5400R).
9)
The combination of upside down and surface reference is not allowed (still possible to set both in Real Time Collector
10)
and from a Terminal program). This mismatch is indicated by this bit. A surface referred column is forced to be sensor
referred if the sensor is placed upside down.
The combination of upside down and surface cell is not allowed (still possible to set both in Real Time Collector and
from a Terminal program). This mismatch is indicated by this bit. The surface cell data is also set as not valid.
