When you do not use the EK15, switch off the display and the computer. If you know that you will not use the EK15 for a long time, we recommend that you also switch off the transceiver(s). Since each transceiver is not provided with a power switch, you must either disconnect the power cable, or disengage the relevant circuit breaker.
Page 17: When You Switch Off The Ek15
Simrad EK15 When you switch off the EK15 You must NEVER switch off the EK15 by means of the on/off switch on the computer. You must ALWAYS exit the EK15 application by clicking the icon on Exit Title Bar If you power down the EK15 by means of the computer switch you may damage the software application and the interface parameters to external devices.
Page 18 The operational frequency is 200 kHz, which offers a very high resolution and high accuracy. You can use the Simrad EK15 with up to 15 Transceiver Units. These will operate in parallel with either simultaneous or sequential pinging.
Page 19: System Diagram
Processor Unit (personal computer) Ethernet switch Transceiver Unit Transducer To control the EK15 operation you can use a standard commercial computer, even a ® laptop. The EK15 application supports Windows 7 operating system. On a larger system with multiple transceivers we recommend using a large display in order to the view all echograms simultaneously.
Page 20: Network Security
Securing the EK15 itself has no meaning unless there is a policy in place that secures all computers in the network, including physical access by trained and trusted users. This must always be a task for the customer to implement.

Page 56: Saving Echogram Sequences (Raw Data)
Raw data files will normally become very large. If you wish to record large amounts of EK15 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.
Page 57: Recalling Single Echogram Images
Save Raw Data Raw data are the echo data received directly from the output of the transceiver. The data can later be replayed on the EK15. The data contain sample data, echo sounder configuration data, navigation data (NMEA format) and annotations (if any).

(a “ping”) into the water. If you observe a pelagic echo on the EK15, and it seems to follow the bottom contour, it may in fact be a false echo from the previous transmission (“ping”). The only way to remove this false echo is to reduce the ping rate.
Page 65 The EK15 is a lot faster, and you may send out a ping even before the energy from the previous ping has disappeared.
Page 66: Selecting Echogram Type
Purpose This procedure explains how to choose the echogram type you wish to see. Description On the EK15 you can choose from several echogram presentations. Surface The echogram is related to the sea surface. Start depth (upper echogram boundary) and vertical range (across echogram) are manually selected by the...

Page 69: Selecting Tvg Gain In The Echogram Dialog Box
The whole idea with TVG is that echoes from fish shall have the same echo level (colour) independent of their depths. The EK15 has a TVG range down to 15 000 meters, which for all practical purposes is unlimited. The EK15 does not have a TVG compensated receiver like most other echo sounders.

Page 71: Removing Interference Using Sequential Pinging
Description function can be used if you have more than one Sequential pinging transceiver/transducer in use on the EK15 system. When activated, each individual transceiver will ‘ping’ in sequence, one by one. When not activated, all transceivers will ‘ping’ simultaneously.

Simrad EK15 Procedure Click the icon. Active This icon is located under the menu. It is used to open the Main Active menu. Click to open the dialog box. Echogram Echogram dialog box allows you to set up the parameters controlling the Echogram echogram presentation.
Page 73: Choosing Automatic Start Depth
If the water depth exceeds 20 meters, the EK15 will automatically move the start range down. The range is kept, but as the start range is moved, the bottom contour is still visible.
Page 74: Choosing The Vertical Range
“fool” the sounder. When the bottom is undetected you will read 0.00 meters depth. In order to guide the EK15 to locate the correct depth, you may some times find it useful to follow this procedure.
Page 75: Biomass Procedures
Do not exaggerate. If you for example enter 5000 meters and the bottom track is lost, the EK15 will search the entire depth for new bottom lock. This will take a lot of time. Click to save the current settings and close the dialog box.

The whole idea with TVG is that echoes from fish shall have the same echo level (colour) independent of their depths. The EK15 has a TVG range down to 15 000 meters, which for all practical purposes is unlimited. The EK15 does not have a TVG compensated receiver like most other echo sounders.
Page 79 Operational procedures School (20 log TVG) This gain setting offers weaker amplification close to the bottom. It has been designed to provide the best echoes for schools. The physical size of a school allows you to detect it even with reduced gain. Fish (40 log TVG) This gain setting provides larger amplification close to the bottom.
Page 80: Transmit Power And Pulse Duration Procedures
Choosing passive mode of operation Purpose In order to check how much noise the EK15 is receiving, you can set it to Passive mode. This means that the EK15 is not transmitting sound pulses into the water, it is only “listening”.
Page 81 The longer pulse duration will provide longer range, but reduced vertical resolution. These filters will reduce the EK15's sensitivity for noise, but the length of the transmitted pulse will give you stronger echoes. With the filters, a longer pulse duration will provide longer range, but reduced vertical resolution.

0.00 to indicate that no reliable detection was obtained. The EK15 algorithm is designed to handle a number of difficult situations. The algorithm maintains bottom lock for a discontinuous jump in bottom depth.

1430 m/s. A good average value to be used in the dialog box is 1470 m/s. Environment The EK15 transmits high energy sound wave pulses Wave propagation from a flat into the sea. A flat bottom reflects the transmitted bottom wave as if it was a mirror.
Page 273: Biomass
Ping-Ping Filter Active but the EK15 receiver will still pick up the transmit pulse and implement it in the calculations. A full synchronization of the various acoustic instruments is required. If your own vessel produces excessive noise this will also be taken into the biomass calculations and provide you with inaccurate information.
Page 274: Bottom Slopes
This means that the sounder can receive both very strong and very weak echoes. Actually, the EK15 will detect echoes from plankton to whales, bottom on most depths, and present the information free from distortion. As a comparison, our old echo sounders ES380 and ET100 had - using analogue TVG - a dynamic range corresponding to approximately 65 dB.
Page 275 For this reason, the EK15 is by default set up to give you a depth reading a few milliseconds before the peak of the pulse. This is done by setting the bottom backstep level to a default value of -50 dB (B).
Page 276 The edge of the beam (A) hits the bottom first, and starts to give an echo. The bottom detector in the EK15 measures the strongest echo, detects what it thinks is the bottom, and starts the white line. The area above the bottom detection...
Page 277: Parameters
The TVG compensation is designed to counteract these natural phenomena, and this is done in the EK15 using digital signal processing. The desired result is that fish of the same size return echoes of the same strength (colour), regardless of range.
Page 278 Simrad EK15 Targets (40 log TVG) Basically, this setting uses the same TVG amplification as , but additional Fish filtering and compensation is implemented. Only echoes detected and interpreted as single fish are shown. The echoes are compensated for their physical position in the beam (beam compensation).
Page 279: Output Power
The echo sounder's transducer converts the electrical input power to a sound transmitted into the water. In the majority of the transducers manufactured by Simrad the transducer's power efficiency is between 50 and 75%. This means that between 50 and 75% of the input power is transmitted as sound.
Page 280 If you use a third party transducer you must manually check that the output power from the Simrad EK15 does not exceed the power rating.

Page 296 The transceivers are provided by Simrad readily set up with a fixed Ethernet address and an IP address. If your EK15 uses two or more transceivers, these will by default have different Ethernet addresses, but identical IP addresses. In order for your system to work, all transceivers must have unique IP addresses.
