Installation Manual
1.
Purpose of this Manual
This installation manual describes the procedures to install the following WASSP equipment:
►►
►►
►►
►►
Transducer
BTxR (Transceiver)
WAASP PC.
WASSP software and firmware for WASSP PC and BTxR.
It also provides procedures to commission the WASSP system during dockside and sea trials.
2.
Introduction
The WASSP is a multibeam Sonar system that uses a wide-angle sonar transducer to profile
the water column and seafloor to a high resolution. It is this unique combination of multibeam
sonar and computer processing power which provides you with unparalleled information about
the underwater environment. It gives you a wide 120° port-starboard swath of the water column
and sea-floor, allowing you to find and position reefs and wrecks, seafloor hardness changes,
and foreign objects in the water column or on the sea-floor. From the 120° swath, the system
processes 224 dynamic beams, with each beam containing detections from the water column
and sea-floor.
The WASSP can be applied to a variety of survey methods, as well as search and rescue,
customs, and police applications.
The information is presented in a user-friendly, mouse controlled, Windows-based operating
system. The system can output data to plotting and hydrographic software packages. For
optimal performance, roll, heave, pitch, heading and position inputs are all required.
The effectiveness of motion correction depends on both the quality of sensors and the quality
of input data. Accurate ship measurements must be taken and the dockside and sea trial
commissioning procedures carried out thoroughly.

Main Features
Simple to use
Improved performance.
The use of separate transmit and receive arrays has enabled WASSP Ltd. to optimise both
transmit performance and receive sensitivity, giving improved performance over traditional
sonar and sounders.
High detail picture of the marine environment.
The transmit beam spreads over a 120° port-starboard swath and covers 4° fore-aft while
the receive beam covers 10° fore-aft, displaying a highly detailed picture of the marine
environment.
Beam stabilisation.
Beam stabilisation compensates for the movement of the vessel, providing accurate seafloor
profiles.
Variable beam width.
Unique to the WASSP, the single beam view can not only be stabilised, but the beam width
can be varied from 5° to 40°.
Bottom lock.
Bottom lock provides a traditional bottom lock mode where the changes in bottom depth are
ignored and the bottom is drawn flat. Echoes are shown relative to the flat bottom image,
enabling better discrimination on the sea-floor.

Computer based profile storage.
A computer-based system means the WASSP can generate and store very detailed seafloor
profiles.
160 kHz operating frequency.
Operating at a frequency of 160 kHz provides high seafloor definition with a large range.
Depth and seafloor coverage.
Seafloor coverage is determined by the beam width in use: For a 90 degree beam width, the
seafloor coverage will be approximately twice the water depth. For example, 100 m depth
gives 200 m seafloor coverage with 224 beams - every ping. For a 120 degree beam width,
the seafloor coverage is 3.4 x depth. For example 200m depth gives over 600m seafloor
coverage.
Unique power management system (14 power levels).
14 power levels provide optimal performance over a wide range of seafloor types and water
depths.
Efficient seafloor mapping.
Profiles 90 times faster than conventional single beam echo sounders, leading to reduced
costs and improved accuracy.
Future proof technology.
The computer based operating system and BTxR firmware are both upgradeable as new
features and methods in software are developed.
Third party integration
Through interfacing, real time, to third party software applications and outputting to standard
formats, bathymetric and water column data can be collected and processed using specialist
tools.

5.1
Transducer
Transducer Type
The WASSP system uses a compact transducer intended to be either pole mounted or flush
mounted inside the hull through a suitable opening to allow the bottom face of the transducer to
be in contact with the sea water.
The compact transducer is a rectangular-shaped, low-profile transducer for through-hull
mounting, encased in a sealed sea chest made to suit the vessel’s hull dead rise angle. The
compact transducer is best suited to steel and aluminium hulls.
A sea chest for housing and sealing the transducer should be designed and constructed by a
reputable shipyard to suit the size and contours of the hull of each individual vessel. This must
be sized and constructed accurately.
The sea chest provides a stable platform for the transducer and must be mounted as horizontal
to the vessel as possible. An optional gland supplied by WASSP Ltd. in alloy, plastic, or steel,
provides the transducer cable through-hull seal.
The Compact Transducer is supplied standard with a 10m cable. Different cable lengths are
available. Please ask your WASSP representative for details.

Transducer Mounting Considerations
5.4.1 Transducer Mounting – General Considerations
The transducer is mounted on the hull below the water line or as a rigid structure attached to the
hull, normally using a permanent sea chest. The transducer must be mounted so that it is aligned
with the fore-aft axis of the vessel. It must also be mounted so that the flat underside of the
transducer is as close to horizontal as possible.
If the vessel has a keel, the transducer can be mounted somewhere along the length of it. If it
is mounted on the hull, it should be far enough away from the keel so that the keel will not be
detected within the 120° beam angle. “Figure 4. Through Hull Transducer Mounting” on page 11
shows a sea chest type through-hull mounting designed specifically for a fast moving, alloy hull
boat.
The performance of the system is directly related to the mounting location of the transducer,
especially for high-speed cruising. The installation should be planned in advance, keeping in mind
the fixed cable length of 10 meters and the following factors:
►►
►►
►►
►►
►►
►►
Air bubbles and turbulence caused by movement of the vessel seriously degrade the
sounding capability of the transducer. The transducer should be located in a position with the
most smooth water flow.
The transducer should not be mounted close to propellers because noise from propellers can
adversely affect the performance of the transducer.
Mount the transducer inboard of lifting strakes as these create acoustic noise.
The transducer must always remain submerged, even when the boat is rolling, pitching or
planing at high speed.
A practical choice would be somewhere between a ⅓ and a ½ of the boat’s length from the
stern. For planing hulls, a practical location is generally towards the rear of the vessel, to
ensure that the transducer is always submerged, regardless of the planing angle.
Do not mount another transducer near the WASSP transducer as it will interfere with the
120° beam.

5.5.1 Mount the Transducer Cable Gland
See “Figure 8. Mounting the Gland Assembly” and “Figure 9. Gland Assembly - Cable Connectors”.
In the external sea chest and fairing type installations, the cable gland forms a seal where the transducer
cable passes through the hull. In low profile sea chest installations, the gland passes through the sea chest
cover.
The gland pipe and a single gasket are the only parts of the gland that are located inside the sea chest or
outside the hull, all other parts are attached to the gland pipe inside the vessel.
Gland Mounting Instructions
Depending on the type of installation, there are various ways of mounting the cable gland to the hull. The
following example describes how to mount the gland through the hull and then feed the cable through the
gland. Adapt the following procedure to suit your installation while taking the following into consideration:
►►
►►
►►
►►
Page 14 of 73
Always use a good quality marine sealant to seal across areas that can leak.
When installing the gland packing ring, apply soapy water to the inside of the packing ring and pass
it over the transducer cable until it is sitting on top of the gland pipe. The soapy water allows the
packing ring to slide easily down the cable. When sitting on top of the gland pipe, clean as much of
the soapy water off as possible to ensure the packing ring grips the cable when pressure is applied by
the gland nut.
Tighten the gland nut by hand until secure. With the vessel in the water, check for leaks at the gland
and if leaking slightly, tighten the gland nut with a spanner until the leak stops.
When all leaks are stopped, tighten the gland lock nut against the gland nut.

5.5.2 Transducer cable Installation
The BTxR uses a transducer cable consisting of seven CAT-5 cables
and one screened pair for the transmit connection.
To fit the RJ-45 connectors and cable through the gland, no special
preparation is required.
The BTxR cable end has the RJ-45 connectors fitted with “staggered”
cable lengths. This allows each RJ-45 connector and its associated
cable to be fed through the gland fitting easily.
Commencing with the black RJ-45 cable and black transmit cable,
feed each cable in turn through the gland, finishing off with the grey
RJ-45 connector and cable.
Complete fitting and tightening the gland as shown in “Figure 9.
Gland Assembly - Cable Connectors” on page 16.

BTxR Installation
6.2.1 BTxR Installation Considerations
For maintenance purposes, the PCB assembly can be removed from the case in situ. Always
leave at least 600 mm clearance at the faceplate end cover to allow the PCB assembly to be
withdrawn from the case.
6.2.2 BTxR Installation
Using the mounting flanges on the end covers, the BTxR can be mounted vertically on a
bulkhead, or horizontally on the floor. See “Figure 10. BTxR Connections and Dimensions” on
page 18 and “Figure 11. BTxR Mounting Diagram” on page 19 for BTxR dimensions and mounting
clearances.

►►
►►
►►
►►
►►
►►
►►
►►
►►
Secure the computer so that it cannot come loose in rough seas.
Keep the computer out of direct sunlight.
The temperature and humidity of the location where the computer is mounted should be
moderate and stable.
Locate the computer away from exhaust pipes and vents.
The mounting location should be well ventilated.
Mount the computer where shock and vibration are minimal.
Keep the computer away from electromagnetic field-generating equipment, such as motors
or generators.
For maintenance and checking purposes, leave sufficient space at the sides and rear of the
computer installation location.
A magnetic compass will be affected if placed too close to the computer. Do not locate the
computer closer than the following compass safe distances to prevent interference with the
magnetic compass:
• Standard compass: 0.8 meters.
• Steering compass: 0.6 meters.

NMEA Interconnection
The WASSP system uses information from the GPS position and ships true heading to create
the seafloor profile displays. This information is normally available on the vessel from existing
sensors. If heading is not available, the GPS course over ground can be used instead, though this
will seriously affect the accuracy of the seafloor profiling.
The WASSP will extract the required data from NMEA input format sentences as well as
proprietary RS232 from supported motion sensors.
For full details on installation and connection, refer to Equipment Manuals.

Hydrographic Software Integration
Hypack Integration
With WASSP / Hypack integration the WASSP-S acts as a realtime data acquisition system and
sends raw angles and depths to Hypack along with timestamped position and attitude data. The
two systems use the GPS ZDA sentence to remain synchronised. No information is sent until
time sync with GPS time is established by WASSP.
9.1.1 Configuration
9.1.1.1Computer
Hypack needs to be installed on a separate PC. Check with Hypack for the specifications
required for this unit.It is important to ensure the computer has a low latency RS232 serial port
for syncing the two systems.
9.1.1.2Serial
Choose a device to use for time synchronisation. This device must output NMEA
or RS232 serial ZDA. Use duplication, a y cable or a low latency splitter <1ms to
send this information to both WASSP PC and Hypack computer. It is normal to also
send position and speed information from this same device along with ZDA. See “8.
Sensors” on page 27 for NMEA 0183 devices.
ZDA should be
configured to output at

9.1.1.3Network
The WASSP PC has an onboard Ethernet network connection which should be connected
directly to the BTxR and a second Ethernet network connection to be used directly to connect
to the Hypack PC. Do not connect the onboard connection to an ethernet network as delays
on this link will directly effect timestamp performance of the WASSP system. This an ethernet
network card is configured for automatic configuration if you wish it to use a specific address
you will need to change the Windows Network configuration.

The Hypack system talks on an ethernet network to the WASSP system. The WASSP
software always uses the port 18007. The Internet Address should be the address of the
2nd ethernet network on the WASSP PC, used for the Hypack connection. This should
be a hard coded IP address rather than using DHCP or DNS server. Enter the relevant
values into the ethernet network Connection Settings spaces provided.

Next setup the Offsets for the Sonar Head and any other device parameters. The GPS
offsets for Hysweep will be added under the Hypack Navigation device. If the WASSP
system is running you can test the Network connection is receiving data but it is easier
to test by running up the data collection process.
Figure 29. Hysweep Device Offsets
9.1.3 Data Collection
When everything is configured select Survey and HYSWEEP Survey. This will open they
HYPACK survey program and the Hysweep Survey interface. The HYPACK side takes care of
position and the HYSWEEP side connects to the WASSP Multibeam to collect Multibeam data,
Attitude and Heave data.
Figure 30. Hypack Survey
When the system first starts the Survey window will have to sync to the WASSP data stream,
this could take up to one minute. The HYSWEEP Survey program once connected will update
the Depth, Time, Roll, Heave, Heading, Pitch, SV values as they are received from the WASSP
system.

Ensure that Boat Info is selected and if the connection succeeds but some data is not updating
there are a few possibilities. Check the Device Selection used by HYSWEEP, under normal
conditions it would be expected that these would be:
Figure 32. Hysweep Device Selections
If a Roll sensor that is not recognised by HYSWEEP is used it may be possible to configure the
WASSP system to convert the sentance to one recognised by HYSWEEP.
If the Roll sensor is not recognised by WASSP you can still feed this to the HYPACK computer
and use this for roll correction.
WASSP and HYSWEEP can be configured to use the same or different sensors for correction.
As long as the two system share the same ZDA the multibeam data will be able to be
synchronised by HYSWEEP along with any other data collected by HYPACK or HYSWEEP.

10. Commissioning
10.1 Commissioning Procedures
Commissioning should be performed by a trained WASSP technician immediately after
installation of the system.
The commissioning procedures are designed to be carried out in sequential order. If a test fails,
fix the system until that test can be completed satisfactorily before continuing. Failure to do this
may invalidate the commissioning procedure. Commissioning procedures are divided into two
sets:
1)
Dockside Tests.
2)
Sea Trials.
For all commissioning steps, the WASSP software needs to be running. See “7.5 WASSP
Software Operation” on page 26. Before these tests are carried out, fill in the Vessel
Identification on the General Tab in Ship Setup Options as this allows data collected on this
vessel to be clearly identified for diagnostic purposes.
Fill in the Transducer

10.1.2Commissioning Step 1: Ship Measurements
Take measurements on the vessel between the vessel’s reference point, the GPS antenna, and
the transducer’s receiver face. These measurements must be as accurate as possible. See
“Figure 35. Ship Measurements Diagram” on page 40. The accuracy of these measurements has
a direct effect on the accuracy of depth soundings. Enter these values in the spaces below, and
on the Offset Corrections tab in the Ship Setup box, see “Figure 34. Ship Setup Options Offset Corrections Tab” on page 39.
Note: The Ships Reference Point is an Arbitrary point close to the ships centre of Pitch and Roll. It pays to make this
point easy to measure to for improved accuracy of measurements. A good guideline for a reference point is a point
near the water line in the centre of the ship (port to starboard) and half way down the length of the ship.

Open the Remote Diagnostics window. Refer to Section “14.1 Open Remote
Diagnostics Utilities” on page 66
The Bar Graph tab is used to diagnose issues with the transducer and wiring. Major
problems with any of the receiver channels should be easy to spot using this facility.
See “Figure 36. I/Q Bar Graphs showing Good Reading” on page 42. As the data comes
in throughout the duration of a ping, the display instantly changes. The I channel is
displayed in GREEN, the Q channel is displayed in RED and magnitude in YELLOW.
The letters along the lower axis are directly linked to the respective 26 channels on
the receiver board and the transducer elements. The slider bar to the right of the bars
controls the gain of the display.
Use the slider bar on the side of the box to adjust the bars so that they fill about a third
of the form height. Ensure there are no extreme (more than 200%) changes in signal
strength across the channels. The display should update regularly and the values
should fluctuate, If one or more bars are full ON or full OFF there is a problem that you
need to resolve before continuing.
The source of problems identified in this test is most likely to be in the connections from
the transducer cable into the BTxR receiver board. If a wire/connector is loose or has
lost some of its insulation you will likely see a blank or very high channel. See “Figure
37. I / Q Bar Graphs showing Problems” on page 42 .

10.1.4Commissioning Step 3: Channel Signal Function
The Scope tab on the Remote Diagnostics Utilities shows a voltage graph of signals received
over a single ping. The sliders at the bottom of the box allow you to change the horizontal
resolution of the graph, allowing you to fit signals onto the screen that would otherwise be lost
off the end of the screen.
You can select the desired channel from the Channel drop downbox. The slider on the righthand side of the box allows you to modify the gain of the graph. The screen in “Figure 38. This
shows a typical Channel Signal Function Diagram” shows a typical transmission pulse with
a reasonably weak bottom return, which is a typical shape. When functioning correctly, all 26
channels should display very similar information to each other.
Adjust the gain and range of the graph so that the graph’s maximum range only just fits on the
axis. The graph should have a small ripple at the beginning followed by a relatively blank period
and then a strong pulse with a rippling tail. This strong pulse is the return from the sea-floor. Use
the selections in the Channel box to view channels A to Z. Check that all of the channels have
similar shaped waveforms on them. If any have non random noise, significant DC offsets or are
without the correct general shape, resolve these problems electrically (check connections).

Note: In very shallow
water it may help to
increase the minimisation
to 5000 as this will
suppress problems
caused by too much
power which could
confuse this process.
Depending on the depth in the dock it may be necessary to start the sea-trial
before this test can be completed fully but overt problems should be able to be
seen even with only 1m of water beneath the transducer.
The transducer number should have been entered in the Ship Setup form
by this stage. If this number is unknown for some reason then setting this
number to the right class of transducer will be necessary before meaningful
seafloor mapping can begin. Currently the classes of transducer are 001
series and 200 series for 160 kHz systems. If the transducer number is not
known set the transducer number to 1 or 200 depending on which gives the
best seafloor results. Having the incorrect value will result in a strange mirror
effect (see”Figure 39. Sonar View with Transducer Number set to correct and
incorrect values.”).

If possible do this test at rest with the engine out of gear and with all other sounding
devices off.
Check the centre line of the Sonar display for a consistent signal or a consistent pulse
down a radial line. If present this is evidence of noise signals common to all channels.
If this noise can be clearly seen as more than a faint blue-white vertical line on the
display, it is likely that all of the receiver channels are picking up electrical noise. If the
display is relatively clean move to the next test. The most likely cause of noise problems
is incorrect termination of the transducer cable grounding and screening. Ensure a
low gauge grounding wire is attached to a solid ground which is common to the power
supply ground.

WASSP will operate better with a source of true heading. If magnetic heading is the only
heading available then enter the magnetic deviation into the Heading Offset. The Heading offset
can also be used to correct for alignment problems between the transducer and the heading
source. Refining this offset is a complex process and requires good position accuracy (DGPS or
better).

10.2 Sea Trials
The second part of the commissioning procedures requires taking the vessel on a short sea trial.
This requires the vessel to leave the dock and perform some basic manoeuvres. The deeper the
water the more accurate the tests can be. Aim for at least 20 metres of water.
10.2.1Sea Trial - Commissioning Step 8: Array Polarity
With the WASSP running and displaying the sonar view, determine if the right side of the sonar
display shows topography that is on the starboard side of the vessel.
If you are unsure of the nature of the seafloor you will need to find a feature such as a rock, bank
or significantly sloped sea profile. Use the waterfall view to navigate and cross your own track
in opposite directions over this feature. If the display seems incorrect, change the polarity of the
Swap Array check box in the Ship Setup Options, Sensor Values tab. See”Figure 46. Swap
Array and Swap Roll Check Boxes”.

10.2.2Sea Trial - Commissioning Step 9 : Roll Correction Polarity
Watch the sonar view carefully when the vessel is subject to some roll. If the roll polarity is
correct the seafloor shown on the sonar view should stay steady as the vessel rolls. If the roll
polarity is not correct, the roll of the sonar display will double what is actually present. If you are
unsure, compare the results with the Swap Roll check box selected and then de-selected.
Note the correct polarity value below and leave the Swap Roll check box in that state.

at the lowest value at which the ring is not visible. See the Full Side Lobe Suppression part of
Figure 34 below.
If this value required is greater than 5000 then it is likely that something is wrong. Check
that the power level is not too high and that you have followed the configuration above and

10.2.5Sea Trial - Commissioning Step 12: Beam Width Reduction
The usable area of the swath may be limited due to reduced beam width caused by low
temperatures, turbulent flow, aeration, high sea state, quick temperature fluctuations or shading
of the transducer.
Watch the outer edges of the Sonar View carefully with the seafloor line shown. If the outside
edges of the seafloor line appear to vary much more than the area immediately adjacent
consider reducing the beam width.
These variance can be seen as frilly edges on edges of a mapped area on the Waterfall Views
and on the Sonar display as perpetually weak echoes on the outer beams. Failure to reduce
the beam width will introduce false data on the outer edges into the backscatter and depth
maps.
To reduce the beam width:
1
On the Menu Task Bar, double click on the Gain Control Knob to open the Advanced
Options Controls.
2
Adjust the Beam Width using the Port and Starboard controls.

Frilly edges will appear on the Waterfall View outer 5 degrees

10.2.6Sea Trial - Commissioning Step 13 : GPS Time Delay (Required)
Most GPS sources used in conjunction with WASSP will have a significant
delay between when the ship passes through a position and that position
is sent on the serial port. This delay may be in the order of 1 second. This
means a 10 knots an object will move 10 metres if passed in opposite
directions at this speed.
10.2.6.1
Some GPS sensors can
smooth the output introducing
more than 15 seconds delay!
Remove GPS Smoothing if the
GPS has this option.
Test 1: For use with standard GPS
To perform this test find a distinct feature eg. big
rock, sharp slope or cable.
Start a new database in Navigator and run over the
distinct object at SOG. (eg. 5kts)
Start a 2nd new database, run back over object in
the opposite direction, same SOG. (eg. 5kts)
Use the measure tool to measure the difference
between the object’s position in the direction the
vessel travelled. If the object appears earlier than
the previous pass then the time delay is positive.
The formula below outlines this process, the delay
adjustment is added to the current Time Lag (Sec)
value on the Ship Setup Options - Sensor Values
Tab - Position
adjustment =
(- late / + early ) change in position in metres

10.2.6.2
Test 2: For use with DGPS
The advantage of this approach over the previous test is it will eliminate pitch errors, however,
the displacement of the object will be smaller and this will be difficult to measure accurately as
GPS errors can make this impossible.
Approach the distinct feature from the same direction at two vastly different known speeds,
as close to zero and at the fastest mapping speed. If the object moves by delta metres further
along the vessel track (+ve) at a faster speed the adjustment to the time delay will be:
delay adjustment =
(- late / + early ) 2 x delta
(fast speed in knots) - (slow speed in knots)
10.2.7Sea Trial - Commissioning Step 14 : Patch Test (Roll)
Before attempting the roll patch test it is suggested that the GPS Time lag and any latencies are
accounted for. Also, it is recommend that you conduct a preliminary adjustment of the Sound
Speed settings to get things in the correct ballpark. Configure Navigator to use Overwrite
mode when mapping depths so that the full extent of any difference is recorded.
1
Use the local chart and local knowledge to identify a spot for the roll patch test – ideally
a flat area between 20-40m – shallower than 10m will make it hard to get an accurate
reading.
2
Run the ship along a line in direction A (it may help to run with the tide and wind behind
the vessel as the return journey is the important one).
3
Turn the ship and make a return journey B so that the same area is mapped but which
the exact opposite heading is used. (It may help to use the navigator heading up
function and COG functions).
Travelling with the tide/wind/
swell (whichever has the
biggest effect on the ships
course over ground if they are
in different directions) on the
first pass will make things much
easier.

depths (2.29m in this case) between the edges of swaths.

Use the Navigator Profile tools to measure the depth displacement between the edges

To compute the sign of the Roll patch look at the Starboard sidetrack as journey B is made.
If this is shallower than track A then the sign for the roll offset is positive. If this is deeper
than the depths from track A the sign for the roll offset is negative.
8
Enter the Roll offset value computed into the Roll Offset setting in the Ship Setup

Repeat these steps in a different area, or on a different Navigator database. If there is still
a significant difference > 50cm add any difference generated to the Roll offset already
computed and then test again. It should be possible to generate a roll offset within 0.1
degrees.

IF GPS Time delay could be completed using variable speed then attempt to compute pitch offset as
follows:
Pitch Correction
Vessel Direction
Requires: >10m depth, Distinct Object, DGPS or better, Accurate Time Lag
Once the Time Lag is accurately ascertained using the variable speed
method described in the previous commissioning step. A Pitch Correction
value can be ascertained by having the Ship travel over a distinct object in
opposite directions. The Object will move if the Pitch offset is incorrect and
use of trigonometry will determine the Pitch offset of between the Motion
Sensor and the Transducer. Enter this number into the Pitch Offset on the
Sensor Values Tab.

A note on heading correction was included in “10.1.7 Commissioning
Step 6: Heading (Yaw) Offset” on page 47. To determine a more accurate
heading correction between the heading sensor and the transducer
orientation we need high accuracy position sensors and corrected seafloor
data. Approach a small distinct seafloor feature so that the port side of the
swath covers the object. Next pass over the object so that the starboard
side of the swath crosses the same object in the opposite direction. It is
important that these two tracks are on exactly parallel heading lines. Use
basic trigonometry to calculate the required heading offset that will allow
the object to remain stationary. Redo the heading test to check that the
heading offset was entered correctly.

waves, depth variance, rocks - whatever is handy. Have the
skipper map an area, ideally with parallel tracks and ‘mow the
lawns’ so that the coverage between each track on the contour
display has some overlap.
It is a good idea to take a copy of raw data recorded during
this Mapping as the data can be analysed in closer detail
at a desk and can be compared to any subsequent data
received from the vessel and may help isolation of a post
commissioning fault.

11. Software / Firmware Upgrade
Software / Firmware upgrades are supplied on a CD, USB memory stick or via download
from the Internet. When you run the new install programme, the WASSP Install.exe program
automatically performs a system check and compares the current versions of software and
firmware against the versions in your system.
Depending on the versions of software and firmware installed in your system, the install program
has a number of responses.
If, while the system check is running, multiple copies of the WASSP system software and
firmware are detected, an Information box informs you of this and states that it is using the last
one for comparison.
As the installer will use the first WASSP application installed, which may be the wrong one, it is
usually better to click OK and then remove all existing copies from your system before going any
further.
This is not an issue if there is only one WASSP application installed.

15.1 UPS Installation and Mounting Dimensions
“Figure 58. 230 V AC UPS Mounting Bracket Outline and Dimensions” on page 70 shows the
physical dimensions of the optional WASSP Ltd. supplied 230 V AC UPS. The hole centres on
the mounting bracket can be used as a template for installing the mounting bracket and UPS.
If installing the UPS, carefully read the supplied manufacturer’s quick start guide and install and
operate the UPS accordingly:
1)
Install the UPS indoors in a controlled environment where it cannot be accidentally turned
off. Place it in an area with unrestricted airflow around the unit, away from water, flammable
liquids, gasses, corrosives, and conductive contaminants. Maintain a minimum clearance of
100 mm on each side of the UPS. Maintain an ambient temperature range of 0°C to 40°C
(32°F to 104°F).
2)
Connect equipment to the receptacles at the rear of the UPS: computers and monitors
should be connected to the ORANGE receptacles for battery back up and surge
protection. Other office machines that do not exceed the capacity of the UPS may be
plugged into either of the two BLACK receptacles that provide surge protection only.
3)
Obtain a suitable input power cable with a minimum cross-sectional area of 1 mm2 to
connect the UPS to the mains supply socket.
4)
Press and release the ON/OFF / Alarm Silence button to turn on the UPS. The UPS
beeps and the mains indicator lights up (GREEN).
5)
Turn on the connected equipment.

15.2 DC Power Supply Mounting Bracket Outline and Dimensions
“Figure 59. 24 V DC Power Supply Unit Mounting Bracket Outline and Dimensions” shows the
physical dimensions of the optional WASSP Ltd. supplied 24 V DC Power Supply Unit (PSU).
The hole centres on the mounting bracket can be used as a template for installing the mounting
bracket and PSU. The PSU has been set to receive 230 V AC input before being attached to the
mounting bracket.
Due to changes in power supply manufacturer, the power supply may differ from the illustration.
However the mounting bracket dimensions and mounting centres remain the same.

15.3 Inverter Outline and Dimensions
“Figure 60. Inverter Mounting Bracket Outline and Dimensions” shows the physical dimensions
of the optional WASSP Ltd. supplied inverter. If installing the inverter, carefully read the supplied
manufacturer’s user manual and install and operate the inverter accordingly ensuring the
environment is:
1)
DRY –
Do not allow water to drop on or enter the inverter.
2)
COOL – The ambient air temperature should be between 0°C and 33°C - the cooler the
better.
3)
SAFE – Do not install the inverter in a battery compartment or other areas where
flammable fumes may exist, such as fuel storage areas or engine compartments.
4)
VENTILATED – The inverter must be well ventilated at all times. Ensure there is at
least 25 mm of space around the inverter. Ensure the ventilation fan and air holes are not
obstructed at both ends of the inverter.
5)
DUST FREE – Do not install the inverter in a dusty environment as the dust can be
drawn into the unit when the fan is operating.
6)
CLOSE TO BATTERIES – Do not install the inverter in the same compartment as
batteries. Do not mount the inverter where it will be exposed to the gasses produced
by the battery, as these are corrosive and prolonged exposure will damage the inverter.
Avoid excessive cable lengths. Use the recommended wire lengths and sizes (detailed in
Section 3-6 of the user manual).
