3.1.3 Installation Description
You can configure the two installation description parameters with any text you wish. Examples
include date of installation, location, etc. NMEA 2000 diagnostic tools such as Maretron
®
N2KAnalyzer
can display this information.
3.1.4 NMEA2000 PGN Enable/Disable
®
The DST110 is capable of transmitting many different kinds of NMEA 2000
messages (or
PGNs) associated with depth, speed, and temperature. You may individually enable or disable
each of these messages.
3.2 Transducer Depth Offset Calibration
The DST110 measures the depth of the water from the transducer, which may or may not be the
waterline depth or the depth of water underneath the keel depending on the mounting location.
Fortunately, the DST110 can be calibrated for reporting the offset from the transducer to the
waterline or the DST110 can be calibrated to report the offset between the transducer and the
lowest point on the vessel. Depth display readings then report either the waterline depth or the
depth under keel depending on your preference.
3.3 Temperature Offset Calibration
The Maretron DST110 may be programmed with an offset value which is added to the water
®
temperature measured by the DST110 before the value is transmitted over the NMEA 2000
network.
3.4 Speed Multiplier Calibration
While the Maretron DST110 as shipped from the factory accurately represents the speed of
water traveling past the paddlewheel sensor, the speed of water past the sensor might not be
the same as the speed of the vessel, due to hull shape or how or where the DST110 is
mounted. The DST110 can be programmed with a multiplier by which the internally calculated
speed through water is multiplied before the speed through water value is transmitted over the
®
NMEA 2000
network. In this way, the DST110 can be programmed such that its transmitted
speed through water can more closely match the speed of the vessel.
3.5 Zeroing the Cumulative Voyage Distance (Log)
The Maretron DST110 automatically logs two different cumulative distances; 1) total cumulative
distance since installation, and 2) cumulative voyage distance since reset. You cannot zero out
the total cumulative distance since installation but you are able to zero out the cumulative voyage
distance since reset.
