'K'xxxxx – Set Minimum Gap Width
'L'xxxxx – Set Minimum Return Width
Sets the current profile return and gap widths where
xxxxx is a five character ASCII value in the range
from '00000' to '16000' (with leading zeros as
required) representing the distance in 1 cm units. The
altimeter performs profiling on ping data to determine
candidates for bottom detection. An acoustic 'return'
is said to be valid if it exceeds a minimum width and
separated by at least a minimum gap between other
'return's at shorter range.
'M'xxxx – Set Custom Maximum Range
'N'xxxx – Set Custom Minimum Range
These commands set the range limits for the custom
range setting 'R0' selected by the Set Range
command, where xxxx is a four character ASCII
value (with leading zeros as required) representing
the range in 10cm units. The allowed minimum range
setting is between '0003' and the current Custom
Maximum Range setting. The allowed maximum
range setting is between '5000' and the greater of the
current Custom Minimum Range or '100'. A couple
caveats apply here:
i.) The minimum range will be the greater of the
Custom Minimum Range setting and the
transmit pulse length.
ii.) The effective maximum range will be limited
by the transmit pulse length, the operating
frequency of the altimeter, as well as the
deployment conditions.
