Installation  
Location should provide as much  
protection from the elements as  
possible.  
Face Plate Installation  
1. To install a face plate:  
a) Attach the face plate to the front panel  
of the instrument.  
The panel for mounting the instrument  
should be 1/8 to 3/4 inch thick.  
b) Twist the face plate clockwise until tight.  
The space behind the instrument panel  
must have a depth of at least 3.75  
inches. See Figure 1 for dimensions of  
the instrument.  
2. To remove face plate, twist it anticlockwise  
until loose and detach.  
2. Drill a 2-inch hole on the instrument panel  
in the selected location.  
Instrument Installation  
The instrument can be easily installed in different  
types of instrument panels. Refer to Figures 3,  
4, and 5 for the following steps.  
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.  
1. Select a suitable location for the instrument.  
When selecting the location for mounting,  
the following are recommended:  
4. Slide the bracket over the body of the  
instrument.  
Controls of the instrument must be  
accessible to the user.  
Note:  
Orient the bracket in such a manner  
that it does not cover the buzzer.  
Electrical connections must be routed to  
the boat system as directly as possible,  
minimising the length of cable where  
practical.  
5. Tighten the mounting nut until the bracket  
is secure.

6. Connect the power cord at the back of the  
instrument to a 12 V power supply which is  
active whenever the ignition switch is on.  
The red lead should be connected to the  
positive terminal of the power supply via a  
1 amp fuse or a 1 amp circuit breaker. The  
black lead should be connected to the  
negative terminal.  
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.  
8. Connect the RCA phono plug on the  
transducer cable to the instrument.

Do not expose a plastic thru-hull transducer  
to solvents. Strong solvents such as  
acetone and methylene chloride attack  
many types of plastics and dramatically  
reduce the strength of plastic parts.  
Accumulation of grease or grime may be  
removed with a damp cloth and mild  
household detergents.  
Transducer Installation  
Note:  
The installation of a transducer is a job  
for a professional boat yard that performs  
numerous installations.  
The following is an informational guide-  
line on the installation of transducers.  
General  
Note:  
Correct installation of the transducer is essential  
for optimum operation of the instrument. Select  
a location for the transducer using the following  
guidelines:  
Transducer cable may be extended  
up to 15 additional feet but depth  
performance may be affected.  
Use 22 gauge, two-wire, shielded cable,  
using RCA/Phono connectors, or use  
EX375D 15 foot extension cable.  
Non-aerated water (bubble-free) water  
must flow across the face of the  
transducer at all speeds if good depth  
performance is to be achieved.  
Never position the transducer directly  
behind shafts, struts, fittings and  
paddlewheel speed transducers because  
water turbulence underneath the  
transducer face can adversely affect depth  
performance.  
Keep the transducer cable away from the  
engine to reduce electrical interference.  
If the boat has bottom paint applied and  
has been used, inspect for areas where  
paint erosion has taken place. Erosion is  
caused by turbulent water and these areas  
are unsuitable transducer mounting  
locations.  
It is very important that the mounting  
location have reasonable access from  
inside the vessel since the transducer will  
require tightening from inside the hull.  
Plastic thru-hull transducers should be  
mounted in fiberglass and metal hulls only.  
Under no circumstances should they be  
used in wood hulls. Swelling of the wood  
may overstress the plastic housing.  
Do not use a fairing block of any type when  
mounting the plastic low profile transducer.  
Hauling or impact can cause structural  
failure of the housing assembly.  
DS41 Owners Manu1a1l  
 
Sailboats  
transducer is not shaded by the prop shaft(s).  
On sailboats, the transducer should be mounted  
where the acoustic beam will not be shaded by  
the keel. A spot forward of the keel is usually  
best. Try to find an accessible spot with a  
minimum deadrise angle. See Figure 4.  
On displacement hull powerboats (such as  
trawlers), the transducer should be mounted  
amidships, relatively close to the keel (centerline  
of the hull).  
On planing powerboat hulls, the transducer  
should be mounted well aft and close to the keel  
to ensure that the transducer is in contact with  
water at higher boat speeds. If the vessel is  
capable of speeds greater than 25 knots, you  
may wish to review installation location and  
operational results on similar boats before  
proceeding. See Figure 5.  
Powerboats  
On IOs transducers mounted close to the engine  
usually yield good results. On inboards, always  
mount the transducer well ahead of the propeller.  
Turbulence from propellers seriously degrades  
transducer performance. Make sure that the

D12S41 Owners Manual  
 
Transom Installation  
In-Hull Installation  
On transom installation, mount your transducer  
as close to the centerline (keel) of the boat as  
possible. On slower, heavier displacement  
boats, positioning the transducer farther from  
the keel is acceptable.  
Transducer installation inside a solid fiberglass  
hull may degrade performance of depth sounder.  
Therefore, this type of installation is not preferred  
over thru-hull and transom installations.  
Should the user desire to perform an in-hull  
installation, perform the following test to  
determine its suitability.  
On two-drive installations, install the transducer  
between drives.  
On single drive installations, mount the  
transducer on the side of the boat where the  
propeller blade is rotating down to minimize  
cavitation. If feasible, mount the transducer at  
least 2 inches (50 mm) beyond the swing radius  
of the propeller. See figure 6.  
1. Fill a thin plastic bag with water and  
suspend the transducer in the water.  
2. Hold the bag against the hull while the boat  
is moored and underway and check the  
reading on the instrument. The reading  
should be relatively constant.  
Note:  
3. The bag may have to be moved around the  
hull to find the best mounting location. the  
best location will be close to the centerline ,  
away from any lifting strakes.  
Do not mount transducer directly behind  
any strakes, ribs, intakes or outlets for live  
wells and engine cooling water, and any  
protrusion that may cause turbulence or  
cavitation.  
To Install:  
After determining that the transducer will function  
inside the hull, construct a water box to be used  
for installation.  
4. Use a PVC pipe with one end threaded and  
supplied with a screw on cap. The PVC  
pipe should be 1/4 inch bigger than the  
bottom face of the transducer.  
5. Install the transducer as shown in Figure 7.  
6. To receive a proper echo from the bottom,  
the bottom of the PVC pipe may have to be  
cut at the deadrise angle of the hull.

Appendix A Dual Station Operation  
Multiple DS41 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.

Appendix B NMEA Repeater Mode  
The DS41 can be configured to operate as a  
NMEA repeater. In this mode it will display depth  
information from any depth sounder outputing  
DPT or DBT NMEA depth data (no other NMEA  
depth sentences are supported).  
To set the DS41 to repeater mode:  
1. Connect the NMEA data and DC power as  
shown in the following diagram.  
2. Apply power to the instrument and  
configure it for slave operation as  
described in the Instrument Setup  
section (Dual Station Operation).  
Notes:  
1) The only information displayed from  
the DPT and DBT sentence is depth  
below the transducer. The user must  
enter keel offset values and alarm  
settings as required.  
2) When a slave has no depth  
information, the display will alternate  
between -- and -SL. This will occur if
