HARDWARE VARIATIONS AND COMPATIBILITY

The 4205 Side Scan System contains both standard and proprietary hardware. At times, EdgeTech may

change the standard components due to their availability or performance improvements. Although the

component manufacturers—along with their models and styles—may change from unit to unit,

replacement parts will generally be interchangeable.

EdgeTech will make every effort to see that replacement components are interchangeable and use the

same software drivers (if applicable). At times, however, direct replacements may not exist. When this

happens, EdgeTech will provide the necessary drivers with the replacement part, if applicable.

EdgeTech may also change certain hardware per customer requirements. Therefore, portions of this

manual, such as parts lists and test features, are subject to change. These sections should be used for

reference only. When changes are made that affect system operation, they will be explicitly noted. Also,

some options and features may not be active in the customer’s unit at the time of delivery. Upgrades will

be made available when these features are implemented.

Contact CUSTOMER SERVICE with any questions relating to compatibility.

4205 SIDE SCAN SYSTEM 0021769_REV_F

1.0 OVERVIEW

The next-generation 4205 is a versatile side scan sonar system that can be configured for almost any

survey application from shallow to deep-water operations. The 4205 utilizes EdgeTech’s CHIRP technology

to provide crisp, high-resolution imagery at ranges up to 50% greater than non-CHIRP systems, allowing

customers to cover larger areas and save money on costly surveys.

The 4205 is available in either a tri-frequency side-scan sonar configuration or a motion tolerant and multi-

pulse configuration. The tri-frequency version allows surveyors the option to operate any two frequencies

simultaneously from the tri-frequency system. Long-range operations, for example, can be achieved with

the selection of the 230/540kHz combination. Then, on-demand the system can be changed to a

540/850kHz system for an even higher resolution survey. The 4205 Motion Tolerant Configuration with

Multi-Pulse (MPMT) provides surveyors the ability to operate either at faster survey speeds or in more

adverse weather conditions while still obtaining high-quality underwater imagery. This configuration can

also be operated in a single pulse (SP) high-definition mode (HDM) for those operations that require a

highly detailed view of the seafloor. In both the SP and MP configurations, the two frequencies are

transmitted simultaneously. In the MP configuration, the sonar doubles the repetition rate. This allows

for increased tow speeds of up to 9.6 knots while still meeting the NOAA and IHO-44S Shallow Water

Survey Specification of three pings on a 1-meter cubed target at 100 meters.

In both the Tri-Frequency and Motion Tolerant/Multi-Pulse configurations, towfish and target positioning

have been improved by integrating a more accurate heading sensor coupled with an optional USBL

beacon. Additionally, all systems now come with increased towfish power to support a wider range of

additional third-party sensors. All EdgeTech 4205 systems are comprised of a topside system and a reliable

stainless-steel towfish. Topside processors come in a choice of configurations from portable to rack-

mounted units. The easy-to-use Discover software is supplied with every unit.

Dual-frequency sonar options include 120/410 kHz, 230/540 kHz, and 230/850 kHz, while tri-frequency

sonar options include 120/410/850 kHz and 230/540/850 kHz. In all configurations, the frequencies are

transmitted as linearly-swept, high-energy acoustic pulses. The received echoes are processed into high

Signal-to-Noise Ratio (SNR) images that can be directly displayed as shades of gray or one of many varying

color palettes on a computer monitor.

The 4205 has a variety of features, including:

• Tri-frequency side scan sonar

• Motion tolerant mode

• Improved target positioning

• Crisp, high-resolution CHIRP images

• Increased Towfish power to support a broader range of additional third-party sensors

• Single-pulse high-definition mode

1.1 4205 Side Scan Sonar System Applications

The 4205 Side Scan Sonar System has many potential applications, including:

1-19

• Cable & pipeline surveys

• Geological/geophysical surveys

• Mine countermeasures (MCM)

• Geohazard surveys

• Channel clearance

• Search and recovery

• Archeological surveys

1.2 Main System Components

The 4205 Side Scan Sonar System is made up of 3 main components:

• Topside processor (Two types are available: 701-DL or Starmux IV, where each version is available

in a rackmount version with EdgeTech configured Computers.)

• Towfish (multiple frequency and performance configurations available)

• Tow cable (Available up to 6000 meters in length)

Contact CUSTOMER SERVICE for questions about cable types and lengths.

1.2.1 Topside Processor

Each of the 4205 Topside Processor options provides downlink telemetry to the towfish for sonar control.

They also receive up-link side-scan data, sensor data, and status information from the towfish for

processing, storage, and display. Each topside processor interfaces with a towfish over a 10/100BaseT

connection, using asynchronous digital subscriber line (ADSL) modems.

There are four types of 4205 Topside processor configurations:

• Starmux IV DL [with or without Laptop]

• 4205 Starmux IV Rack Mount (FIGURE 1-1)

o Starmux IV and 2U Computer inside Case

o Keyboard / Trackball

o LCD Monitor

• 701-Digital Link DL [with or without a Laptop].

• 4205 701-DL Rack Mount (FIGURE 1-2)

o 701-D-Link and 2U Computer inside a 6U Hardigg Case

o Keyboard / Trackball

o LCD Monitor

Starmux IV and 701-DL Rack Mount options come with a preconfigured EdgeTech 2U Windows 10

computer with Discover Installed. If just the digital link is purchased, users can install Discover on their

computers or buy an EdgeTech Windows 10 laptop with Discover installed.

Detailed information can be found in both the 701-DL AND STARMUX IV HARDWARE MANUALS.
