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 currently available in 3 configurations:
» WSP-603-200; DRX wideband model

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.

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
• 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. All AC/DC inverters and DC/DC converters should be switched o to maximise system sensitivity.
CAUTION: Operating outside the temperature specification will reduce the operating lifetime of the DRX. For specifications, see “9 Technical
Specifications” on page 57.
CAUTION: Operating outside the temperature specification will reduce the operating lifetime of the DRX. For specifications, see “9 Technical

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 15
» The second option is horizontal on a hard, flat surface. See “Figure 5. DRX Horizontal
Mount” on page 15.
» If mounted in an enclosed space, forced ventilation is required to maintain an
ambient temperature within the stated limits around DRX. See “Figure 4. DRX
Bulkhead Mount” on page 15and “Figure 5. DRX Horizontal Mount” on page 15Leave 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 53 for DRX dimensions and mounting clearances.
Hard Surface

Figure 4. DRX Bulkhead Mount Figure 5. DRX Horizontal Mount

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.
• Mounting screws; Minimum M6 x 40mm x 4
• When installing the DRX, thread locking fluid or locking washers are recommend to avoid vibration loosening
» DRX should be always be mounted on a hard surface capable of supporting the DRX
weight.

Remote Power
Connector AUX
A local supplied latching switch can be connected to pins four (Remote PWR On) and five (Remote PWR On GND) of connector DATA1 (RS-232). 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.7 Remote Power” on page 64 for connection specification.
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.8 KP1/KP2 In” on page 65 for connection specification.
KP1 OUT
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).
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.11 Ethernet” on page 67 for connection specification.
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 ping rate of the DRX over the connected sounder.
See “Appendix A.9 KP1 Out” on page 66 for connection specification.
PPS IN
Connectors RS422 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 32.

Connector FAN
Availability dependent on model.
The fan connector powers the optional single or double fan assembly.
See “Appendix A.13 FAN” on page 68 for connection specification.
Grounding Point
The grounding point is used to minimise the pickup of noise from interfering sources.
For optimal performance, connect the earth lug on the DRX 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.
The DRX is designed to be run on DC voltage from 9-32 Vdc.
See “Appendix A.10 Power Connection” on page 67 for connection specification.

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.
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 47.

DRX INSTALLATION MANUALDRX INSTALLATION MANUAL

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

Figure 24. 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.

Figure 23. GPS Time Delay Stage 1

wassp.com wassp.com
Version: 2.0 July 2016

Figure 25. GPS Time Delay Stage 3

Doc: DRX Installation Version: 2.0 July 2016
The formula below outlines this process.
DRX INSTALLATION MANUALDRX INSTALLATION MANUAL
adjustment =
( - late / + early ) change in position in metres
speed in knots used in both directions
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
35.
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)

Figure 26. Manual Roll Patch Test

5.3.2. Roll Oset
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.
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).

DRX INSTALLATION MANUALDRX INSTALLATION MANUAL
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 40 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.
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.

Figure 27. Measurement of Swath Width H

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.
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 35.
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 35.

Figure 28. Pitch Corrections

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.
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.
