1 INTRODUCTION

The WASSP DRX is a ‘Black Box’ smart transceiver that interfaces to devices and sensors to make up the WASSP Multibeam Sounder System.

The system can be conﬁgured to operate in various modes, typically using a wide-angle sonar transducer to proﬁle the water column and seaﬂoor in high resolution.

Using appropriate sensors, the DRX can be conﬁgured to be suitable for operations such as commercial ﬁshing, sport ﬁshing, survey and mapping, exploration, search and rescue and many more.

Actual data types output to client applications, such as WASSP CDX, will be determined by:

» Data types enabled in DRX, as determined by the licensing model. » Data types the client application supports and queries for. » If the client application is using raw, processed or post processed data . » Data types that are supported will increase through continual product development

and DRX upgrades.

The DRX functionality is deﬁned by the software installed, the data types enabled, the transducer connected, and the physical DRX model. The physical DRX model is supported in 4 conﬁgurations:

» WSP-603-200; DRX-25 wideband model (no longer available).

1.1. MAIN FEATURES

The main features of DRX in a multibeam conﬁguration will depend on the model as follows:

» Variable number of beams - Model and conﬁguration dependent. » 120° Swath coverage – Transducer dependent. » Depth capability is conﬁguration and environment dependent. Typical

conﬁgurations:

• DRX-25 with WMB160 transducer; 1 to 150m

• DRX-32 with WMB160 transducer; 1 to 200m

• DRX-46 with WMB160 transducer; 1 to 400m

• DRX-46 with WMB80 transducer; 2 to 600m » Variable frequencies. » Supported by multiple client applications to meet dierent customer requirements. » Direct Ethernet connection to multiple client applications. » Continuous real-time 2D and 3D mapping. » Easy to operate and quick to install. » Web based setup and conﬁguration. » Beam stabilisation. » Variable beam width.

» WSP-603-200; DRX-32 wideband model used with S3 and F3 products. » WSP-603-205; DRX-32 wideband model with IP67 rating. » WSP-603-250: DRX-46 wideband model used with F3X.

The same software package is applicable to all models.

2 SYSTEM OVERVIEW

The WASSP multibeam sounder system requires the following components:

DRX; Transmit, receive, digital signal processing, display processing, License management

and data server for client applications.

WASSP TRANSDUCER; See WASSP Transducer Reference Manual. PC; Control, post processing and viewing of sounder, sonar and mapping needs to be

handled by a suitable application, running on PC or tablet.

GPS; Position and time required for water column and bathymetry geo-referencing. HEADING SENSOR; Required for correctly orienting the multibeam data. MOTION SENSOR; Required for stabilising the water column and bathymetry data for

vessel roll, pitch and heave.

SOUND VELOCITY PROBE; Required for correcting Sound Velocity in order to improve

depth accuracy across the swath.

SOUND VELOCITY PROFILER; For accurate range measurement, sound velocity needs

to be known at the transducer and through the water column. The Sound Velocity Proﬁle information can be applied if using 3rd Party applications supporting SVP.

NOTE: As with any multibeam sounder, the quality of the sensors connected will directly aect the performance of the system. Enhancements to system performance include using high precision RTK GPS, accurate sound velocity measurements, sound velocity proﬁles, and high performance motion sensors. Your WASSP dealer can advise on sensors to suit your requirements. WASSP recommended sensors are also detailed in this manual, see “Appendix B -

Supported Sensors and Sentences” on page 82.

DRX INSTALLATION MANUAL DRX INSTALLATION MANUAL

3.1. INSTALLATION PARTS

Standard supply:

» 1 x DRX unit » 4 x Connector plugs » 1 x power cable » 1 x LAN cable » 1 x USB Flash Drive:

• Find My DRX Application

• WASSP CDX Application

• WASSP Utilities

• License key for Data Manager

» Depending on kit:

• Transducer installation kit (a package with a transducer cable clamp, a TX connector and installation manual)

• Widescan Sensor package (refer to Sensor Box Installation Manual)

» WASSP DRX Installation Manual

3.2. TRANSDUCER

• Keep away from exhaust pipes and vents.

» Avoid electrical and acoustic noise as this will have a direct impact on system

performance:

• Avoid locations close to electrical equipment such as inverter, converters and other power supplies.

• Keep away from electromagnetic ﬁeld-generating equipment such as motors and generators.

» To avoid damage to the DRX:

• Locate where Shock and vibration are minimal.

• The area should not be prone water ingress or high moisture content.

CAUTION: Electrical or acoustic noise will directly impact system performance and signal integrity. AC/DC inverters and DC/DC converters will impact system sensitivity and can cause system noise even if not directly connected. If an AC/ DC or DC/DC PSU is required only use low noise, good quality products in order to minimise impact on system performance.

CAUTION: Operating outside the temperature speciﬁcation will reduce the operating lifetime of the DRX. For speciﬁcations, see “9 Technical

Speciﬁcations” on page 69.

Refer to Knowledge Base for guidelines on the Operating Environment. “Appendix E - Product Registration, Support and Resources” on page 89.

The DRX supports multiple transducer types and can be setup to operate in a variety of conﬁgurations. Typical setup will be multibeam wideband mode with:

» WMB160 » WMB80

Detailed speciﬁcation and mounting methods for supported transducers is described in the WASSP Transducer Installation Manual.

Transducer selection is described in “5.2.4. Data Setup Tab” on page 37.

3.3. LOCATING THE DRX SYSTEM

The DRX is a highly sensitive receiver which is capable of discerning signals of less than one microvolt. In order to get the highest performance out of the DRX system keep the transducer, transducer cable and the DRX far away from sources of electrical and acoustic noise. AC/DC inverters and DC/DC converters are particularly noisy and even if not used to power the system, should be kept as far away as possible.

The DRX will need to be located with access to all required sensors. This needs to include transducer cable, GPS, motion sensor and LAN connections. Serial cables from sensors should be run direct to DRX with no splitters or interfaces boxes.

When selecting a mounting location, keep the following points in mind to maintain optimal performance:

» Maintain ambient temperature in the vicinity of the DRX within operating

speciﬁcations. Operating in temperatures outside of speciﬁcation will result in reduced operating lifetime or direct failure due to overheating:

• The area needs to be well ventilated in order to avoid local ambient increase from self heating.

• Keep out of direct sunlight. Exposure to sunlight will result in direct solar gain

3.4. MOUNTING THE DRX

Installation & Mounting Considerations

The DRX can be installed on a desktop, deck or on a bulkhead. Using the mounting ﬂanges on the bottom plate, the DRX is mounted vertically on a

bulkhead, or horizontally on a hard surface. Important considerations are:

» A vertical position is ideal for optimal thermal performance (Transducer Connectors

front face down). See ”Figure 4. DRX Bulkhead Mount” on page 16.

» The second option is horizontal on a hard, ﬂat surface. See “Figure 5. DRX Horizontal

Mount” on page 16.

» If mounted in an enclosed space, forced ventilation will be required to maintain an

ambient temperature within the stated limits around DRX. See ”Figure 4. DRX Bulkhead

Mount” on page 16. and See “Figure 5. DRX Horizontal Mount” on page 16.

» Leave slack in cables for maintenance and servicing ease. » For maintenance and checking purposes, leave sucient space at the sides and rear

of the DRX installation location.

» Fasten the DRX to the mounting location with a minimum of four self tapping

screws. See Section “7 Outline Drawings” on page 61 for DRX dimensions and mounting clearances.

• Mounting screws; Minimum M6 x 40mm x 4.

• When installing the DRX, thread locking ﬂuid or locking washers are recommend to avoid vibration loosening.

• Anti Vibration Mounts are recommended.

» DRX should be always be mounted on a hard surface capable of supporting the DRX

weight.

Figures 4 and 5 show clearance required for cabling and forced air ventilation if DRX is in an enclosed space.

Before installing the DRX in an enclosed space ensure that the ventilation is sucient to prevent overheating. Consider the following:

» Cool air supply needs to be able to adequately dissipate the thermal output of DRX. » Ensure the hot exhaust air from the enclosed area does not recirculate into the DRX.

Perforations in the top will assist in removing exhaust air.

» Install the DRX in a position to allow the air ﬂow to circulate eectively through the

outlet.

» Route all cabling to minimise blockage of airﬂow.

NOTE: If operating in a high ambient environment forced airﬂow over the DRX will signiﬁcantly improve thermal performance. Always make sure that there is adequate ventilation.

3.5.3.2. Connectors and Components – Back Plate

RS-232 IN/OUT

Connector RS232 RS-232 is a serial connection for sensors/processors that natively output RS-232. For

NMEA 0183 talkers it will depend on the instrument as to whether it will be RS-232 compliant or require a converter. RS-232 supports power out at same voltage as DRX power supply.

See “Appendix B - Supported Sensors and Sentences” on page 82.

RS-232 can be conﬁgured using the DRX SETUP WEBPAGES. See “5.2. Commissioning

Step 2: Sensor Conﬁguration” on page 34. See “Appendix A.4 RS-232” on page 73 for connection speciﬁcation.

RS-422 IN/OUT

Connector RS422-A and RS422-B RS-422 is a serial connection for sensors natively outputting RS-422 or by using RS-232 to

RS-422 converter. For NMEA 0183 talkers it will depend on the instrument as to whether it will be RS-422 compliant or require a converter.

The RS-422 Connector also supports PPS IN:

KP1/KP2 IN

Connector AUX KP IN interface is to allow the DRX to transmit in sync with another sounder/sonar. This

feature is useful for helping reduce transmit pulse interference. KP IN takes the key pulse from an external system (master) and synchronises the DRX

(slave) transmit pulse with that key pulse as a trigger.

See “Appendix A.9 KP1/KP2 In” on page 78 for connection speciﬁcation. See “5.2.6. Key Pulse Tab” on page 40 for connection information.

KP1 OUT

Connector AUX KP OUT interface is to allow the DRX to transmit in sync with another sounder/sonar.

This mode allows the DRX to be the KP master, and the receiving sounder/sonar to be the slave. This feature is useful for helping reduce transmit pulse interference.

This mode is recommended to optimise the nterference immunity from the connected sounder.

See “Appendix A.10 KP1 Out” on page 79 for connection speciﬁcation. See “5.2.6. Key Pulse Tab” on page 40 for connection information.

» RS-422-A supports power out at same voltage as DRX power supply » RS-422-B allows data forwarding and power out at same voltage as DRX power

supply

See “Appendix B - Supported Sensors and Sentences” on page 82.

RS-422 can be conﬁgured using the DRX SETUP WEBPAGES. See “5.2. Commissioning

Step 2: Sensor Conﬁguration” on page 34. See “Appendix A.5 RS-422-A” on page 74 and “Appendix A.6 RS-422-B” on page 75

for connection speciﬁcations.

NMEA 0183

Connector 0183 NMEA 0183 is a serial connection for sensors natively outputting NMEA 0183 (single

talker, multi listener). As well as an NMEA input, this connector also features an NMEA output.

The 0183 Connector also supports PPS IN.

See “Appendix B - Supported Sensors and Sentences” on page 82.

NMEA 0183 can be conﬁgured using key DRX SETUP WEBPAGES. See “5.2.

Commissioning Step 2: Sensor Conﬁguration” on page 34. See “Appendix A.7 NMEA 0183” on page 76 for connection speciﬁcation.

Remote Power

Connector AUX A local supplied latching switch can be connected to pins eight (Remote PWR On) and

nine (Remote PWR On GND) of connector AUX. When the switched is closed the DRX will power on. When the switch is open (circuit open) then the DRX will power o.

See “Appendix A.8 Remote Power” on page 77 for connection speciﬁcation.

PPS IN

Connectors RS422-A, RS422-B and 0183 Pulse-per-second (PPS) input allows connection equipment with a PPS timing output.

PPS input allows the DRX to be accurately synchronised with GPS UTC enabling highly accurate positional timing accuracy, potentially improving mapping data positional accuracy by removing GPS latency issues.

Through the DRX SETUP WEBPAGES the user can choose which PPS input is tied to which input, and view that the signal is being correctly received. See “5.2. Commissioning

Step 2: Sensor Conﬁguration” on page 34. See “Appendix A.5 RS-422-A” on page 74 and “Appendix A.7 NMEA 0183” on page

76 for connection speciﬁcation.

Power

The DRX is designed to be run on DC voltage, see specs in “9 Technical Speciﬁcations”

on page 69. See “Appendix A.11 Power Connection” on page 80 for connection speciﬁcation.

Ethernet

Connector LAN The Ethernet link is used for all communication between the client application running

on PC (or other devices) and the DRX. This link is used for control of the DRX and for the DRX to supply data for visualisation and post processing to the client device.

The Ethernet connection can be connected either:

• directly using crossover cable or auto crossover (DRX supports auto MDI/MDI-X) OR

• via a network switch if supporting multiple clients or running the DRX on vessel LAN (local area network).

wassp.com wassp.com

Version: 5.0 June 2018

Doc: DRX Installation Version: 5.0 June 2018

The Ethernet connection needs to support at least Gigabit network to enable full functionality.

If there is a DHCP server on the LAN, the DRX will be assigned an appropriate IP address by the DHCP server. If there is no DHCP server, the DRX will fall through to Zeroconﬁguration assignment in block 169.254.0.0/16. Any connected device will need to be assigned an appropriate IP address on the same subnet as the DRX, either via DHCP server, Zero-conﬁguration or ﬁxed IP.

See “Appendix A.12 Ethernet” on page 80 for connection speciﬁcation.

3.6.1. DRX Setup Webpages

DRX SETUP WEBPAGES are used for upgrade, setup, feature licencing and conﬁguration.

For more details see “4 Operating the DRX” on page 24 and “5 Sensor Conﬁguration”

on page 32.

The DRX SETUP WEBPAGES are launched by opening any supported web browser and entering the DRX IP address followed by port 2001 e.g. 169.254.54.69:2001

The grounding point is used to minimise the pickup of noise from interfering sources. The earth lug on the DRX should be commected to a good earth point on the vessel. Use

a short braided cable for optimal noise rejection.

CAUTION: Noise due to poor grounding will have direct impact on DRX performance and signal integrity.

3.6. DISPLAY AND CONTROL DEVICES

The DRX supports two levels of communication over the Ethernet link; web browser based DRX SETUP WEBPAGES and IP based DRX client applications.

In order to initiate communication with the DRX the client needs to know the DRX IP address. This can either be done through the client application discovery mechanism or using the ‘FIND MY DRX’ Help utility.

The ‘FIND MY DRX’ utility can be run on any PC connected to the DRX over the Ethernet connection. ‘FIND MY DRX’ will ﬁnd any DRX on the network by IP address.

NOTE: The PC only needs a physical Ethernet connection to ﬁnd DRXs on the network. IP address and subnet is unimportant, however, for connectivity the DRX Client Application needs to be on the same TCP/IP Subnet.

NOTE: Clicking on the appropriate DRX in ‘FIND MY DRX’ will automatically launch the web browser with the appropriate URL.

NOTE: Chrome browser, shipped with DRX, is fully supported. Other browsers may not behave as expected. If webpage does not update use CTRL F5.

CAUTION: Only one instance of ‘DRX SETUP WEBPAGES’ should be run otherwise a corruption may occur.

3.6.2. DRX Client Applications

Ethernet IP is used for discovery, control and data through supported DRX client applications. Current supported client applications include WASSP CDX, 3rd Party Navigation, sounder and survey applications and are described in “6 Control and Display

Application Support” on page 55.

NOTE: For DRX client application connection, the DRX and client application need to be on the same TCP/IP subnet.

If DRX and client applications have incompatible IP addresses, discovery will succeed but connection will fail.

5.3. COMMISSIONING STEP 3: ON WATER PATCH TESTS

On water patch tests are essential for correctly conﬁguring the DRX. The accuracy of the values derived from these patch tests will directly impact system performance.

These patch tests can be run using various tools including those in 3rd Party application such as HYPACK, WASSP Patch Test Utility shipped with WASSP CDX or manually through WASSP CDX. The sections below describe methods for running patch tests manually using WASSP CDX.

5.3.1. GPS Time Delay

Most GPS sources used in conjunction with WASSP will have a signiﬁcant delay between when the ship passes through a position and when that position is sent on the serial port. This delay may be in the order of 1 second. This means at 10 knots an object will move 10 metres if passed in opposite directions at this speed.

IMPORTANT NOTE: NMEA Buer and multiplexers can add signiﬁcant delays to serial data. Any conﬁguration change will require recalculation of delays. All connections from sensors should be direct to DRX..

NOTE: If using PPS input to synchronise to UTC time (conﬁgured through the DRX SETUP WEBPAGES) the GPS time delay will be automatically accounted for, and the GPS Patch Test is not required.

Test 1: For use with standard GPS

To perform this test, ﬁnd a distinct feature such as a big rock, sharp slope or cable.

1. Run over the distinct object at SOG (e.g. 5kts).

Page 48 of 92 Page 49 of 92Doc: DRX Installation

wassp.com wassp.com

Version: 5.0 June 2018

Figure 25. GPS Time Delay Stage 1

2. Run back over object in the opposite direction, same SOG (e.g. 5kts) and drop a mark on the same spot.

Doc: DRX Installation Version: 5.0 June 2018

DRX INSTALLATION MANUAL DRX INSTALLATION MANUAL

4. The delay adjustment is added to the current Time Lag (Sec) value in the DATA

SETUP section of the DRX SETUP WEBPAGES. See “5.2.4. Data Setup Tab” on page

37.

Test 2: For use with DGPS

The advantage of this approach over the previous test is that it will eliminate pitch errors. However, the displacement of the object will be smaller and this will be dicult to measure accurately as GPS errors can make this impossible.

Approach the distinct feature from the same direction at two vastly dierent 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:

( - late / + early ) 2 x delta

adjustment =

(fast speed in knots) - (slow speed in knots)

5.3.2. Roll Oset

Figure 26. GPS Time Delay Stage 2

3. Use the measure tool to measure the dierence between the object’s position in the direction the vessel traveled. If the object appears earlier than the previous pass, the time delay is positive.

Before attempting a roll patch test it is suggested that the GPS Time lag and any latencies are accounted for. Also, it is recommended that you conduct a preliminary adjustment of the Sound Speed settings to get things in the correct ballpark. Conﬁgure the mapping width to be at the maximum 120° for best results.

The WASSP Patch Test Utility, shipped with CDX, can be used to automatically calculate and apply Roll Oset. Alternatively, Roll Oset can be manually calculated.

Manual Roll Patch Test

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 where the exact opposite heading is used. It may help to use the Heading Up and COG functions.

Figure 27. GPS Time Delay Stage 3

The formula below outlines this process.

( - late / + early ) change in position in metres

adjustment =

DRX INSTALLATION MANUAL DRX INSTALLATION MANUAL

NOTE: the measurement is the distance of the line in this case rather than the depth change – this depth change across the swath is not used.

6. Use a calculator (one is present in Windows) to compute tan(a) (D/H) e.g.

a. Run window Calculator, Select ‘View: Scientiﬁc Mode’ b. Enter D (e.g. 2.8) c. Press ‘/’ d. Enter H (e.g. 73.23m) e. Press ‘=’ f. Select ‘Inv’ g. Press ‘tan-1‘ h. Record this number as the Patch Roll Quantity

7. To compute the sign (positive roll or negative roll) of the Roll patch look at the Starboard side-track as journey B is made. If this is shallower than track A then the sign for the roll oset is positive. If this is deeper then the depths from track A the sign for the roll oset is negative.

Figure 28. Manual Roll Patch Test

NOTE: Showing path A and path B overlapping. Measurement D is the change in the depths (2.8m in this case) between the edges of swaths.

4. Use the WASSP CDX Proﬁle tool to measure the depth displacement between the edges of the swath on one side. This value is D. It will help to stop pinging while making the measurement so that the swath does not get overwritten.

5. Measure the entire width of the swath at the point you have measured the displacement. This value is H (73.229m in this case).

8. Enter the Roll oset value computed into the Roll Oset setting in the DATA SETUP section of the DRX SETUP WEBPAGES. See “5.2.4. Data Setup Tab” on page 37.

9. Repeat these steps in a dierent area, or on a dierent Mapping database. If there is still a signiﬁcant dierence > 50cm add any dierence generated to the Roll oset already computed and then test again. It should be possible to generate a roll oset within 0.1 degrees.

5.3.3. Pitch Oset

If GPS time delay can be completed using variable speed, See ‘Test 2 For use with DGPS’

“5.3.1. GPS Time Delay” on page 49 then attempt to compute pitch oset as follows:

Pitch Correction

Requires: >10m depth, Distinct Object, DGPS or better, Accurate Time Lag.

1. 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.

Version: 5.0 June 2018

2. The object will move if the Pitch oset is incorrect and the use of trigonometry will determine the Pitch oset between the Motion Sensor and the Transducer.

3. Enter this number into the Pitch Oset in the DATA SETUP section of the DRX SETUP WEBPAGES. See “5.2.4. Data

Setup Tab” on page 37.

5.3.4. Heading Oset

Requires: DGPS or better, Distinct Object and >10m depth.

To determine an accurate heading correction between the heading sensor and the transducer orientation we need high accuracy position sensors and corrected seaﬂoor data.

1. Approach a small, distinct seaﬂoor feature so that the port side of the swath covers the object.

2. 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.

3. Use basic trigonometry to calculate the required heading oset that will allow the object to remain stationary. Redo the heading test to check that the heading oset was entered correctly.

6 CONTROL AND DISPLAY APPLICATION SUPPORT

The DRX system is supported by a number of PC and/or Tablet based applications for DRX control and data post processing, data storage and data visualisation.

For detailed operating instruction refer to the applications’ appropriate user manual. Supported applications and connection procedures are outlined here.

NOTE: DRX SDK and API with integration instructions are available from WASSP Ltd.

6.1. CONNECTING THE WASSP CDX TO THE DRX

WASSP CDX ships free with DRX and can be installed directly from the USB Flash Drive.

1. After installing WASSP CDX on your PC, start the DRX and run WASSP CDX.

2. WASSP CDX will automatically select the DRX as long as the network has been correctly conﬁgured.

3. To manually select the DRX you wish to connect to:

tan(α) = -d/(2w) α = tan-1 (-d/2) If object moves as above the sign is negated otherwise remove the -ve sign from this

equation.

4. Enter the calculated value for a into the Heading Oset in the DATA SETUP section of the DRX SETUP WEBPAGES. See “5.2.4. Data Setup Tab” on page 37.

5.3.5. Patch Test Validation

With on water patch tests complete the conﬁguration can be checked.

1. Find an area with distinct features such as sand waves, depth variance, rocks etc

2. Map the area with parallel overlapping tracks in both directions.

3. Validate alignment of the features.

Any misalignment will be due to inaccuracies in the commissioning values that have been applied.

Open the HOME menu and select DEVICES.

NOTE: Navigation to DEVICES will depend on CDX version.
