1 Operation
Whenever power is applied the depth sounder is
active and water depth is displayed. If the sonar
signal does not show a bottom the display will
indicate “- -”. This can occur if the water is aerated
or the maximum depth is exceeded.
Shallow Alarm
To set the shallow alarm:
1. Press
show:
for three seconds. The display will
ON
Press for 3
Seconds
Note: The maximum depth decreases as boat speed
increases.
Alarms
2. After a few seconds the display will indicate
the current Shallow Alarm depth setting.
Two types of alarms can be set; the Deep Alarm
and the Shallow Alarm. The Deep Alarm can be
set as high as 184 metres (605 feet) while the
Shallow Alarm can be set as low as 0.3 metre (1
foot).
Whenever the water depth is greater than the
Deep Alarm setting and the alarm is enabled an
alarm will sound. The alarm repeats two short
beeps and alternates DAL and the water depth
on the display.
3. Use
and
to change the value. If either
key is held depressed for more than one
second the reading will increase or decrease
rapidly.
Whenever the water depth is less than the
Shallow Alarm setting and the alarm is enabled
an alarm will sound. The alarm repeats a single
long beep and alternates SAL and the water
depth on the display.
4. When the alarm is set, exit by pressing both

keys are pressed for a period of 5 seconds the
normal depth display will resume.

will be retained for future use.
4. When the alarm is set, exit by pressing both
and
simultaneously. Alternatively, if no
keys are pressed for a period of 5 seconds the
normal depth display will resume.
2 Instrument Setup
Note: A negative offset is used to display depth
below the keel and a positive offset is used to display
depth below the surface.
Keel/Surface Offset
An offset may be automatically added to
or subtracted from the depth reading to
compensate for the location of the transducer.
This allows the instrument to indicate the water
depth relative to the bottom of the keel or the
surface of the water.
4. Use
and
to change the value. If either
key is held depressed for more than one
second the reading will increase or decrease
rapidly.
5. The offset can be programmed in 0.1 unit
steps from -9.9 to 9.9 feet (or equivalent).
When programmed for a negative offset, ‘-’
will be indicated on the left hand side of the
display.
To set the keel/surface offset:
1. Apply power while holding down
.
ON
Hold down during power up
6. To display depth below the keel enter the
vertical distance between the bottom of the
keel and the depth transducer as a negative
value.
2. When the unit is on, release . The display
will indicate if the current offset is keel offset
or waterline offset:
7. To display depth below surface enter the
vertical distance from the waterline to the
depth transducer as a positive number (no
negative sign).
Hull Offset (Depth below the keel)
8. To exit this mode, press and hold both
simultaneously. Alternatively, if no keys
are pressed for a period of 5 seconds normal
depth display will resume.

and
Transducer Setting
A Transducer Setting is provided to allow
the Explorer D210 to be used with different
transducer types. The default setting (= 0.0) is
used for most transducers.
Units of Measure
To select the displayed unit
1. Apply power while holding down
.
Some transducers ‘ring’ after the sonar transmit
pulse (just like hitting a bell). This ringing can be
interpreted as an echo from a shallow bottom.
The setting is used to increase the required level
that shallow echoes must meet before they will
be displayed.
OFF
Hold down during
power up
2. When the unit is on, release . The display
will indicate the current display unit with:
If the Explorer D210 gives repeated false readings
of 1.5 to 3 feet depth while in deep water the
transducer setting should be increased. Adjust it
upward by 0.5 at a time and re test. The range of
values is -0.9 to +2.5. If the value is set too high it
could cause erratic readings in shallow water.

3 Dual Station Operation
Multiple Explorer 210 instruments can be
installed on a single vessel. These instruments
can be connected together and configured to
operate in a dual station configuration. One
instrument is designated as a master and all other
instruments, connected to it, are configured as
slaves. The master device is connected to the
depth transducer and determines the water
depth. This information is then displayed on all
slave devices connected to it. Slave devices do
not have transducers connected to them.
the master device, and share common alarm
settings and keel offset values. In this mode
the common alarm settings can be changed or
activated/deactivated from either the master or
slave devices.
Alternatively, the slaves can be configured to
operate as independent slaves. In this mode the
slaves display the water depth received from the
master, but have independent alarm settings and
keel offset values.
Note: The instrument designated as the
master device is the only instrument connected to
the depth transducer.
The slave devices can be configured to operate
as fully functional NMEA repeaters where
they display water depth, as displayed on

Note: The keel offset and units of measure should
only be changed on the Master instrument.

Example: Switching an alarm off on the slave
instrument will also switch the alarm off
on the master instrument. The reverse also
applies, alarms changed on the master will be
automatically changed in the slave instrument.
Note: This setup procedure applies to the master
device and all slave devices. For separate operation
all devices, including the master, must be set to
Separate mode. Also, for linked operation all devices,
including the master, must be set to Linked mode.

4 Maintenance
Your depth sounder is designed for years of trouble free operation assuming proper installation and care
are provided. Following the operation and installation guidelines in this manual should ensure optimum
performance of the instrument. In the unlikely event that the instrument shall fail to perform or shall
need servicing, contact the dealer whom you purchased your Explorer D210 from.
5 Installation
The red lead should be connected to the
positive terminal of the power supply via a 1

1. Select a suitable location for the instrument.
terminal.
When selecting the location for mounting,
the following are recommended:
•
Controls of the instrument must be
accessible to the user.
•
Electrical connections must be routed to
the boat system as directly as possible,
minimising the length of cable where
practical.
.75”
19 mm
3.75”
95 mm
•
•
Location should provide as much
protection from the elements as possible.
7. Obtain the power from a 12 V source as
directly as possible. Avoid power circuits
which share loads with ignition, alternators,
radio transmitters, etc. Excessive electrical
noise associated with such devices may
prevent the instrument from operating
properly.
The panel for mounting the instrument
should be 3 mm to 19 mm (1/8 to 3/4
inch) thick.
•
The space behind the instrument panel
must have a depth of at least 95 mm (3.75
inches).
8. Connect the RCA phono plug on the
transducer cable to the instrument. Extension
cables are available from your Northstar
dealer if the transducer cable is too short.
2. Drill a 51 mm (2-inch hole) on the instrument
panel in the selected location.
3. With the mounting bracket removed, insert
the instrument into the hole until the back
of the face plate is flush with the outside
mounting wall.
