Page 7: Introduction
INTRODUCTION The SCAN-650 is a high performance imaging sonar system available in two different package configurations which enables it be used on large or small ROVs. It can also be pole-mounted and used from a small boat in shallow water. - Page 8 The most common application is mounting the scanning head on an ROV. The ROV can rest on the bottom or hover just off the bottom and the sonar scans 360 degrees looking for targets. SCAN-650 scanning head mounted on Fishers SeaLion ROV.

Page 9: System Components
SYSTEM COMPONENTS Signals from the scanning head travel up the cable to the Sonar Processor on the surface. The signals are processed and sent to the PC where the signal is displayed and recorded. The boat’s GPS receiver can also be connected to the Sonar Processor. If connected, the boat’s Latitude and Longitude will be displayed and recorded by the PC. - Page 10 LEFT BLANK...

Page 11: Theory Of Operation
The fact that scanning sonar sweeps the beam back and forth across the bottom gives a major improvement over the depth sounder printout for bottom detail. Not only can very small targets be detected but the details of the target can be seen. Signal SCAN-650 Signal SCAN-650 Top View (very narrow signal) - Page 12 THEORY OF OPERATION (continued) The JW Fishers SCAN-650 scanning sonar operates by transmitting a short, high energy, narrow width acoustic wave. This high energy acoustic wave hits directly below the transducer first (as shown below) Fish Transducer Acoustic Wave 100 m Range Switch...

- Page 14 TIME VARIABLE GAIN (TVG) The Sonar Processor contains a TVG circuit on the PC board that receives the echo signals from the fish preamplifier boards. The TVG circuit amplifies and makes time variable gain adjustments to the signal to make up for signal losses which occur when the echoes are traveling through the water;...
- Page 15 The TVG amplifier has three operator controls. They are located on the top panel of the Sonar Processor. Recommended settings for the TVG controls are provided in the Operation Section of this manual. Final TVG adjustments are made by the operator while the unit is running. The function of these controls is to adjust the amplifiers to compensate for losses that occur when the signal travels through the water.

SONAR PROCESSOR Computer: The system will run on a Laptop, Desktop, or on JW Fishers optional “Splash Proof” computer. The “Splash Proof” is a computer system that is built into a Underwater Kinetics case. It utilizes a 10” Ultra Bright” display which is much easier to read in a open boat.The Sonar Processor has an integrated interface board that converts the analog signals to digital, and inputs the signal to the computer. - Page 17 • POWER INPUT - The power input for the Sonar Processor can be any voltage between 9 and 12 volts dc. A wall transformer is also supplied with the SCAN-650 which allows the Sonar Processor to be powered from 120/220 volts ac. The wall transformer converts 120/220 volts ac to 12 volts dc.
- Page 18 • Open file - Use this to open an existing sonar file for playback. • Save screen as a picture - Saves the image on the sonar screen as a Bitmap file. • Print screen - Prints the image shown on the screen. • Exit - closes the SCAN-650 program.
- Page 19 OPERATOR SWITCHES AND CONTROLS (continued) View: The number of toolbars available under VIEW depends on the display resolution selected for the monitor. The higher resolution settings permit a single large toolbar (Mode/Screen Toolbar), where a lower resolution setting (640 by 480) requires three toolbars (Standard/Playback/Screen Position) to show the same number of icons.
- Page 20 OPERATOR SWITCHES AND CONTROLS (continued) separate file (see page 24 for details). Settings: • Set Serial Port number - The Sonar Processor has an integrated USB to Serial communications port. The operator must select the Sonar Processor com port for proper operation. Note: Use the same physical USB port on the PC every time.
- Page 21 OPERATOR SWITCHES AND CONTROLS (continued) TOOL BARS: Mode/Screen Toolbar- The Mode/Screen toolbar allows for easy 1-click access to many software functions.

- Page 23 OPERATOR SWITCHES AND CONTROLS (continued) TOOLBARS: (CONTINUED) Settings Toolbar Displayed on the right side of the screen. Information and pull down menus are: - Range - The range setting sets the radius of area to be scanned. Range settings of: 5, 10, 20, 40, or 60 meters are available. A 360° sweep with a range setting of 10 meters would result in a total scan diameter of 20 meters.
- Page 24 - Run Time - Shows the running time of the sonar. This is the time from when the SCAN-650 application is opened, or a new recording is started. - Time - Shows the time of day (gets the info from the computer). Under Settings (top toolbar), 12 hr or 24 hr clock can be selected.
- Page 25 OPERATOR SWITCHES AND CONTROLS (continued) SCREEN POSITION (under the View Menu and Mode/Screen Toolbar) The operator can move the origin point (center) of the sweep to any position on the screen to give a large viewing area. Moving the origin point and increasing the zoom extends the image from the top to the bottom of the screen.

Interface board (analog to digital board). The second program is a USB to Serial Driver. This pro- gram is required for the PC to control the Sonar Processor Settings. The third program, SCAN-650, is the actual operating software. All Software must be installed before the Sonar Processor is con- nected to the computer with the included USB cable. - Page 28 13. A messagebox will appear stating ‘You must restart your computer for the con- figuration changes made by JW Fishers SCAN-650 to take effect. Click on ‘Yes, I want to restart my computer now’ and ‘OK’ to complete the InstaCal installation.
- Page 29 If you are using your own computer system then proceed below. (If your SCAN-650 connects to your PC using a PC-CARD or PCI board (desktop PC) skip to page 26) When you first connect the Sonar Processor SP to PC Interface (USB Cable), the Windows “Found New Hardware Wizard will launch.
- Page 30 For PCI board (Desktop PC) Before the SCAN-650 can be used for the first time, this program must be run to configure and calibrate the Interface board. This program will also need to be run if the Interface board has been removed and replaced in the PC or moved to a different slot on the motherboard.

Page 39: Faqs
How do I adjust to compensate for a bottom that slopes away or towards the scanner head? The SCAN-650 produces a fan shaped beam that is 40 degrees in the vertical plane. This allows the SCAN-650 to scan gently sloped bottoms without altering the orientation of the scan- ning head. - Page 40 SCAN-650. Lowering the SCAN-650 to the bottom of a lake or pond on a self leveling tripod ensures the scanning head is perpendicular to the bottom and in the proper position for scanning a fairly level bottom (as is common in most ponds).

The JW Fishers Sonar requires a COM (serial) port to pass operation parameters from the PC to the Sonar. It will be necessary to configure the JW Fishers Sonar software to open the correct COM (serial) port for communications. Below are instructions for configuring the COM (serial) port. - Page 42 The driver software for this interface board is installed as part of the JW Fishers Sonar application installation process. After the JW Fishers Sonar application installation process is completed and before the sonar system is run for the first time, a program to configure the interface board must be run.
