DRX INSTALLATION MANUALDRX 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.
For specification details on each model see “10 Technical Specifications” on page 75.
NOTE: DRX Serial numbers below #70 are model DRX-25.
DRX Serial numbers #70 and above are DRX-32.
DRX Serial numbers #10001 and above are DRX-46

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

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 39.
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

Version: 7.1 January 2021
Doc: DRX Installation
Version: 7.1 January 2021
wassp.com wassp.com
DRX INSTALLATION MANUALDRX 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 “10 Technical
Specifications” on page 75.
Refer to Knowledge Base for guidelines on the Operating Environment.
“Appendix I - Product Registration, Support and Resources” on page 101.
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 17.
»The second option is horizontal on a hard, flat surface. See “Figure 5. DRX Horizontal
Mount” on page 17.
»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 17. and See “Figure 5. DRX Horizontal Mount” on page 17.
»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 “8 Outline Drawings” on page 66 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.
CAUTION: Operating outside the temperature specification will reduce
the operating lifetime of the DRX. For specifications, see “10 Technical
Specifications” on page 75.
.
CAUTION: IF DRX is mounted in an enclosed space forced ventilation as
described below is required.

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.
