Simrad ES70
7 = unit – M, f or F for depth measurements, C or F for temperature measurements
unit
= source – number (1, 2 or 3) of the sensor providing the current data values
8
source
9 = channel – the number (1 to 30) of the communication channel for the
chan
current data source
10 = value – the magnitude of the current sensor measurement
val
11 = change rate – the magnitude of the current depth or temperature measurement
crate
= quality:
12
qual
• 0 = No connection between the sensor and the receiver
• 1 = One or two telemetry pulses are lost, current value is predicted
• 2 = The current data value is reliable
= interference:
13
infe
• 0 = No interference
• 1 = Interference detected
14 = signal level – the signal level of the telemetry pulse, measured in dB // 1 µPa
siglev
= noise level – the average noise level of the current channel, measured in dB
15
nlev
// 1 µPa
16 = the current gain; 0, 20 or 40 dB.
gain
= cable quality:
17
cable
• 0 = cable is not connected
• 1 = cable is OK
• 2 = a short circuit, or the hydrophone current is too large
= error detected – 0 when no error is detected, a number >0 indicates an
