080-085On/Off on / off the drogue
The coding method for drouge sensor is different by ID numbers, as the following table.
ID numbersdrogue 'on'
2200 -255.00
4600 -0.00
8200 -0.00
8600 -255.00
8700 -0.00
11000 -0.00
12000 -0.00
17000 -255.00
When the sensor stays in a normal position while the drogue survives, it will keep 'off'. Once the drogue is gone, the sensor switch will get turned 'on'. If the tether for the drogue is cut below the subsurface float, the buoyancy of the float will turn the sensor upside down and the switch will be turned 'on'.
