Use the Altimeter Configuration Window to set appropriate parameters for your altimeter:
The Altimeter Configuration Window allows you to select an SDC serial communication port that you
will use to accept data from the altimeter and to set its communication parameters. Note that the 440
and 440 systems can have different offsets. Although a single altimeter is present, its height above the
440 and 440 coils will be different.
The altimeter test allows you to see the serial data transmitted by an altimeter connected to the SDC.
The values shown will not have any meaning until the altimeter is immersed in water.

❐ Altimeter connected via Sub-sea Electronics Pod (for altimeters marked *
and ** above)

Fixed coil alti-
tude
If there is no altimeter fitted and the design of the ROV allows the coils to
remain at a fixed altitude above the seabed, enter this altitude in centimetres.
Altimeter off-
set
Enter the height difference, in centimetres, between the reference line of the
440 coil array and the transducer face of the altimeter.
Use a positive value if
the altimeter is above the coils.
