Interfaces on the Auxiliary plug
• Analogue heave sensor (pins 3 and 16)
– One differential input is connected to the sensor output
terminal, the other input is grounded at the sensor in order
to prevent ground potential offsets between the sensor and
the transceiver from being adding to the sensed signal. The
differential input range is ±10 V.
• Temperature sensor (pins 4 and 17)
– Some transducers contain a built-in temperature sensitive
resistor, normally 10 kohm at 25°C. This resistor is used to
measure the water temperature.
• Supply voltages (output)
– Pin 5: +12 Vdc, max 100 mA (Ground on pin 18)
– Pin 6: -12 Vdc, max 100 mA (Ground on pin 19)
– Pin 7: +5 Vdc, max 200 mA (Ground on pin 20)
