• Remote control and data subscription • Calibration program The Simrad ME70 scientific multibeam echo sounder is looking downwards, and it is designed for high operating flexibility. The system includes a wide fan of stabilized beams for fish behaviour studies, fish school characterization and other purposes. A sector of these beams can be set up as split beams providing data for single target analysis such as target strength measurements and target tracking.

Simrad ME70 System diagram A basic ME70 system diagram is provided. Interface capabilities, uninterrupted power supplies and power cables are not shown. Processor Unit with (CD016019-010) colour display Transceiver Unit Power Supply Units SIMRAD Transducer MENU The following main interfaces are required:...
Ethernet cables. Transceiver Unit The Simrad ME70 Transceiver Unit is housed in a 19” instrument rack. In order to reduce the loss in the transducer cables, the transceiver is physically located as close as possible to the transducer. The transceiver computes and generates the electric signals sent to the transducer to form a transmission - a ‘ping’.
Transceiver Unit using 25 cables. Support information If you need technical support for your Simrad ME70 you must contact your local dealer, or one of our support departments. A list of all our dealers is provided on http://www.simrad.com.
Getting started Getting started This chapter describes how to get started with the basic operation of the ME70. It contains a brief overview of the basic system operation and procedures. If you are a first time user, we recommend that you read through this chapter while operating the ME70 so that you can familiarize yourself with the menus, dialog boxes and display presentations.
If this is the case, leave the system idle for approximately 30 minutes, then do the Restart procedure. Prerequisites The ME70 Transceiver Unit is connected to the ship’s mains and set up for operational use. All the circuit breakers in the Transceiver Unit are engaged.
Getting started Note You must never switch off the ME70 only by means of the on/off switch on the computer. This may damage the software or the interface parameters for external devices. You must ALWAYS use this procedure. Powering off the computer will not automatically power down the Transceiver Unit.
Mouse The computer mouse can be used to control the functionality provided by the ME70. The mouse controls the movements of the cursor, and the buttons are used to click on buttons and select parameters.
Getting started Trackball All ME70 functions can be controlled with the trackball. The ball controls the movements of the cursor, and the buttons are used to click on buttons and select parameters. Trackballs come in several shapes and sizes. A generic version is shown as an example only.
Echogram(s) Each echogram is presented in its own . There are five channels views, Channel view and these will by default take up the largest part of the ME70 display presentation. 378945/B...
Page 25
Getting started By default, you will have five channel views open. Each of these views provide one echogram that can be surface related and bottom related. If you click in a channel view, the echogram is selected to be “active”. The “active” echogram is identified with a thick red border.
These buttons are used to control basic system functions. • : Click this button to close down the ME70 application. Exit • : Click these buttons to adjust the size of the ME70 Minimize Resize presentation. • : Click this button to open the context sensitive on-line help.
The menu system is by default located on the right hand side of the ME70 presentation. The selection of operational parameters on the ME70 is done using a tree structure with a main menu, a set of submenus, and several menu buttons. Some of the menu buttons open dialog boxes or submenus to offer additional choices.
Click anywhere on the button to open a separate dialog box. Starting normal operation Once you have powered up the complete ME70 system, you are ready to start the actual operation. When started up, the ME70 will automatically apply its previous setup parameters.
Raw data files will normally become very large. If you wish to record large amounts of ME70 raw data, make sure that you have enough space on you hard disk. Unless your computer is equipped with a very large disk capacity, we recommend that you save the raw data to an external storage device.
To play back the raw data files, see Replaying raw data on page 45. Selecting beam mode Purpose The ME70 allows you to create and edit beam modes. Each beam mode contains specific parameters that define the properties of the mode; number of beam sectors, mean characteristics, frequencies etc.
Normal operation must then be selected to use the new mode. Selecting operational mode Purpose This procedure explains how to set up the ME70 for normal operation and start ‘pinging’. Description The ME70 allows you to choose between these operational modes: •...

) the system will neither transmit Ping nor receive. Active The ME70 transmissions of acoustic energy into the water is active according to the parameters defined. • If the pinging has been enabled ( set to ) the system will perform its Ping normal operation.
Simrad ME70 Selecting the vertical range Purpose This procedure explains how to set the vertical range; the distance from the sea surface and down to the bottom. This vertical range is controlled by on the menu. Range Main Example 1 Start Range and Range in bottom related echogram In a bottom echogram, set the value to –5 meters.
Maximum Level Do not confuse this function with the function. Gain Procedure Observe the menu. It is located on the right hand side of the ME70 Main presentation. Observe the button on the menu. Gain Main Note that there are two buttons.
Saving the current user settings Purpose This procedure explains how to save the current configuration and parameter settings. Procedure Observe the menu. It is located on the right hand side of the ME70 Main presentation. On the menu, click to open the dialog box.
The ME70 is provided with an extensive context sensitive on-line help system. All information of the ME70 Reference manual is also provided in the on-line help. The on-line help is located in a single proprietary Microsoft CHM file. This CHM file will also run on any other computer provided that the computer runs a Microsoft operating system.
This chapter contains several operational procedures explaining how you can put your ME70 to use. Menu navigation employed by Simrad ME70 is similar to the other Simrad applications which follow the user interface standards developed by Simrad. The main menu is normally located at the right side of the screen, and by means of dedicated icons at the bottom of the main menu, you can open the relevant submenus or dialog boxes.

If the file size limitation is too small, and does not match the sailed distance value, the ME70 will place the raw data for each sailed distance in several individual files. The current size of the file being recorded is displayed in the appropriate Current text field.
Raw data files will normally become very large. If you wish to record large amounts of ME70 raw data, make sure that you have enough space on you hard disk. Unless your computer is equipped with a very large disk capacity, we recommend that you save the raw data to an external storage device.
Purpose This procedure explains how you can play back (recall) raw data. Important The system is not operational when you have chosen Replay mode: the ME70 is then not able transmit. Related topics • Defining the parameters for raw data recording on page 42 •...

This is typically a large capacity USB memory device or a harddisk. You can also connect the ME70 computer to a network, and copy the files to a server. Use the functionality provided by the operating system to delete the files, or to copy or move them to the separate storage device.
Simrad ME70 Enabling and disabling information fields in the channel and swath views Purpose Observe this procedure to enable and disable the various information fields offered by the channels and swath views. Description Each channel and swath view will by default present the echogram for the chosen beam and swath, as well as information about the beam parameters.
This procedure explains how to choose which beams to see in the five channel views. Description Five channel views are provided in the ME70 presentation. There are three views next to each other in the top “row”, and one on each side of the Swath view. Each channel view provides the echogram for the chosen beam.
