DRX INSTALLATION MANUAL
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).
»
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.

3.2. TRANSDUCER
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
Page 14 of 92
wassp.com
Doc: DRX Installation
Version: 5.0 June 2018
DRX INSTALLATION MANUAL
• 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
Refer to Knowledge Base for guidelines on the Operating Environment.
Appendix E - Product Registration, Support and Resources” on page 89.
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.
»
If mounted in an enclosed space, forced ventilation will be required to maintain an ambient temperature within the stated limits around DRX.
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 sufficient 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 sufficient 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 effectively 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.

Grounding Point
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.

5.1. COMMISSIONING STEP 1: SHIP MEASUREMENTS
Take measurements from the GPS antenna, motion sensor and transducer to the vessel’s reference point.
See “Figure 16. Ship Measurements Diagram” on page 33
These measurements must be as accurate as possible.
The accuracy of these measurements have a direct effect on the accuracy of the recorded data.
Enter these values in the spaces below, and in the SENSOR INSTALLATION tab within the
SENSOR tab of the DRX SETUP WEBPAGES .
See “Figure 19. DRX Setup, Sensor Tab” on page 37.
NOTE: The Ships Reference Point is a 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.

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 Buffer 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).

Doc: DRX Installation
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
wassp.com
Page 49 of 92
DRX INSTALLATION MANUAL
Figure 26. GPS Time Delay Stage 2
3. Use the measure tool to measure the difference 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.
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
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 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: adjustment =
( - late / + early ) 2 x
delta
(fast speed in knots) - (slow speed in knots)
5.3.2. Roll Offset
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 Offset. Alternatively, Roll Offset 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. adjustment =
( - late / + early ) change in position in metres speed in knots used in both directions

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).
Doc: DRX Installation
Version: 5.0 June 2018
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 offset is positive. If this is deeper then 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
DATA SETUP section of the DRX SETUP WEBPAGES .
See “5.2.4. Data Setup Tab” on page 37.
9. Repeat these steps in a different area, or on a different Mapping 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.
5.3.3. Pitch Offset
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 offset 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 offset is incorrect and the use of trigonometry will determine the Pitch offset between the Motion Sensor and the Transducer.
3. Enter this number into the Pitch Offset in the DATA SETUP section of the DRX SETUP WEBPAGES .

DRX INSTALLATION MANUAL
5.3.4. Heading Offset
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 offset that will allow the object to remain stationary. Redo the heading test to check that the heading offset was entered correctly.
