< WARNINGS >1/2

1. THE REAR PANELMOUNTED TRANSDUCER CONNECTORS ARE

EMITTING EXTREMELY HIGH VOLTAGE RADIOFREQUENCY PULSES.THESE CONNECTORS ARE COVERED WITH A SCREWLOCKEDPROTECTIVE RUBBER CAP WHEN THE EQUIPMENT IS INITIALLYDELIVERED.

TO AVOID COMING INTO CONTACT ACCIDENTALLY WITH THECONNECTOR PINS, BE SURE TO PLACE THE PROTECTIVE CAP:

OVER THE UNUSED, EXPOSED CONNECTOR, IF THE EQUIPMENTHAS A SINGLE TRANSDUCER PLUGGED IN, OR

OVER EACH CONNECTOR WHENEVER EXPOSED PINS BECOMEEASILY ACCESSIBLE, SUCH AS WHEN EITHER TRANSDUCER ISUNPLUGGED FOR INSPECTION OR SERVICING, AND

LOCK THE CAP WITH THE TWO SCREWS ATTACHED.

2. THE ACCURACY OF THE ONSCREEN DEPTH READOUT ISAFFECTED BY WATER TEMPERATURE, SALINITY, DEPTH ANDOTHER UNDERWATER CONDITIONS AS WELL AS THE SHIPSROLL AND PITCH, HEEL AND TRIM.

TAKE THESE POSSIBLE ERRORCAUSING FACTORS INTOCONSIDERATION WHEN USING THE DEPTH READOUT, SUCH ASWHEN NAVIGATING SHALLOW AREAS OR IN APPLICATIONSWHERE ACCURATE DEPTH READING IS CRITICAL.

3. DURING SHALLOW WATER OPERATION, THE EQUIPMENT MAYOCCASIONALLY READ TWICE THE ACTUAL DEPTH BY LOCKINGONTO THE*1SECOND BOTTOM ECHO.

THE DIGITAL DEPTH READOUT SHOULD BE COMPARED WITH THEGRAPHIC BOTTOM INDICATION OR WITH SOUNDINGS DATA INOFFICIAL PAPER CHARTS TO DETERMINE THE TRUE DEPTH.

TOTAL RELIANCE ON THE DIGITAL READOUT ALONE FOR DEPTHINFORMATION IS DANGEROUS AND MUST BE AVOIDED.

*1See paragraph 3.4.2 for more information on the second bottom echo.

4. WITH A *2TRANSDUCER DRAFT ENTERED, THE ONSCREEN DIGITALREADOUT SHOWS THE DEPTH FROM THE WATERLINE AND NOTFROM THE TRANSDUCER OR FROM THE SHIPS KEEL.

GREAT CARE SHOULD, THEREFORE, BE TAKEN IN USING THEDEPTH READOUT WHEN NAVIGATING SHALLOW WATER AREAS. BESURE TO SET THE DEPTH REFERENCE TO BELOW SURFACE(DBS) TO AVOID ANY MISUNDERSTANDING.

*2 See paragraph 4.2 for more information on transducer draft.

1. Registration of Transducer ChannelLocation Assignments

After installation of the transducers,

register the assigned channel, frequency and mounting location of each transducerin the table below so that the operator can tell which transducer is in use for currentsounding,

attach an appropriate name/ID tag to the plug of each cable (or mark each plugappropriately) for ease of identifying transducers when the transducers areunplugged for maintenance or servicing, and

do not turn the equipment on until the transducers are placed in water.

Transducer ChannelLocation Assignments Table

Detailed installation instructions are given in section 9.

2. UsingSKIPPERIR 301Digital Depth Repeater

Depth output data ($PSKPDPT, proprietary data format) required for depthindicatingoperation of the IR 301 is initially disabled. Be sure to turn the output (abbreviatedPSKDPT on the menu) on via the procedure given in paragraph 4.12 when that remoteunit is plugged into the rear panel 8pin I/O DATA connector.

The IR 301 has only two transducer location indicator LEDs (forward and aft) on its display.When your system has one transducer mounted in the middle of the hull, the output includeslocation data MID in its string, which is not supported by the IR 301. Therefore the positionof the selected transducer, when installed in the middle, will not be indicated on the IR 301.See paragraph 9.3.4.2 for data format information.

F-2000Product Description

(continued on next page)1

1. Product Description

The Model F2000 is a dual frequency navigation echo sounder designed to comply fullywith IMO Resolution MSC. 74(69) Annex 4.

Built around an 8inch daylightviewing, highcontrast color TFT LCD screen, theequipment displays the bottom topography using a total of seven userdefinable easeontheeye analog strengthlevel colors representing various layers of the bottom stratum.The display can be set to show the bottom contour alone in a single color via amenuguided procedure.

Digital depth readout is also available using easytoread large fonts with a clear onscreenindication of the reference of measurement (from the waterline, transducer or keel), and inmeters, fathoms or feet. To comply with the IMO resolution, the depth must be indicated inmeters for navigational purposes.

With appropriate optional sensors plugged in, the ships LAT/LON coordinates, speed,heading and water temperature will also be displayed at the same time.

A batterybacked realtime calendar clock is built in to indicate the date and time in UTC or inthe desired local time. With an appropriate GPS sensor plugged in, the time is automaticallyreferenced to the atomicprecision GPS time.

Up to 24 hours of sounding data will be stored in nonvolatile memory at approximatelytwosecond intervals, together with associated date and time, range and frequency in useplus position and water temperature, and can be played back easily with a devoted key. Theuser can review the stored data across any 15minute segment at any point in time over thepast 24 hours through a specially designed window. The data can be output on demand inNMEA0183 (IEC 61162 1)compatible format via rear panel connectors for use inshorebased applications, and is protected against a system reset.

An easytouse menu system is incorporated to set the transducer draft, depth reference,echo threshold level, echo display mode, etc. in addition to operating parameters to beselected mainly at installation time. Unauthorized access to the menu system can beprevented with password entry, if desired.

Equipped with a powerful 1 kW RMS dual frequency transceiver, the F2000 operates on twodifferent channels (channelA and channelB) separately. The channel can be easilyswitched with a devoted front panel key. A 200W lowpower dual frequency transceiver isoptionally available for operation using ELAC 50 and 200 kHz transducers, and STN ATLASSW 6016 100 kHz transducers.

The output power level is adjustable, automatically to suit the range in use, or manuallywhere more power is needed in shallow water soundings over a soft, muddy bottom.

Both the receiver gain and TVG (anticlutter) levels are automatically controlled forhandsfree operation. Manual override of both functions is also possible for each operatingchannel.

If it is desired to display echogram for a longer period of time, lower feed rates (plot speeds)can be chosen without affecting the sounding rate specified for the depth range in use,thereby allowing the current information updating rate to be maintained regardless of thefeed speed in use.

Possible interference from other echo sounders operating in the vicinity can be effectivelyeliminated or reduced with a 3step noise reduction function.

1. Product Description (continued 2/2 )

The acquired data will also be output via the rear panel RS232C and RS422 connectorssimultaneously for use in applications requiring depth, date/time and position information. Ifwater temperature data is needed, a thermistor sensor is optionally available and can beplugged into a devoted connector. The dual frequency transducer supplied by themanufacturer has the sensor embedded in its molded housing.

To obtain a hardcopy of the present screen, a Centronics parallel port is also provided,which supports commercially available DOS/Vcompatible monochrome graphics printerswith ESC/P control protocol.

The builtin alarms include depth alarm, bottommissing alarm, power failure alarm andpower removal/shutoff alarm.

The depth alarm alerts the operator to decreasing depth (shallow alarm). A variable depthmarker can be turned on to set the alarm depth graphically as well as digitally.

The bottommissing alarm warns against the bottom echo being lost, becoming too weak orexceeding the current range limit.

The power failure alarm will be activated if the power line voltage drops below thefactoryspecified predetermined level.

The alarm activation status will be indicated both audibly and visually, and the alarm outputswill be separately available for driving externally connected alarm devices through a devotedconnector.

The power removal/shutoff alarm, independently controlled by a devoted circuit based on ahighspeed large capacity condenser, will be triggered in the event power is removed orshut off with the F2000 operating, emitting a repeating beep for several minutescontinuously. A devoted reset switch is provided on the front panel to silence the warning

sound.

The display cabinet has a rugged DC power supply built in that allows reliable operationover a wide range of voltage fluctuations, and an AC power adapter unit (Model AC2000)is separately supplied as standard. In an installation where an AC power source is available,the equipment can be operated primarily from the AC source with automatic changeover tothe DC power source for uninterrupted operation in the event of AC power outage.

Figure 3-1 Typical FullScreen FullColor Echogram Display

*1Optional GPS sensor or GPS data source required. *2Optional temperature sensor required.

Bottom Echo

The bottom echo is shown in up to a total of seven different colors, depending on thestrength. The colors used to display the bottom are shown on the color scale ( ) inorder of strength. Red, initially at the lower end of the scale, represents the strongestpart of the echo (i.e. hardest layer of bottom stratum), and blue initially represents theweakest part (i .e. softest layer of the bottom). It is possible to display only the contourof the bottom in a single color via the menuguided procedure. See paragraph 4.9 for

Depth Readout

The depth to the bottom from the selected reference () is indicated here.

Readout Unit: m=meters (default), FM=fathoms, BR=braccia, FT=feetRefer to paragraph 4.10.3 for details.

< CAUTIO N >To comply with IMO resolution MSC.74(69), measurements must be made inmeters for navigational purposes.

To obtain a continuous readout, the bottom echo ( ) must be displayed in red, orangeor yellow (or three userdefined strongest echo colors). This is automaticallyaccomplished when you are operating the unit in the fully automatic control mode(AUTO,).

If you are operating the unit in the manual control mode (MANUAL,), adjust theappropriate gain control accordingly. The TVG level may also have to be adjusted toprevent surface clutters from disturbing depth reading. See paragraph 3.10.

If the bottom echo is lost or too weak to measure depth continuously for 4 seconds ormore, (or if the depth exceeds the current range limit continuously for 4 seconds ormore when in the manual control mode), the bottommissing alarm will be triggered,blinking the current readout unit on a red background with digital readout turned off, andemitting a beep at approx. 1second intervals. To rectify this situation, activate themanual control mode, and increase the receiver gain or select a greater range. Seeparagraph 3.12.3 for details about the alarm function.

Depth Reference

The reference to which measured depth is to be referred is indicated here.

BELOW TRANSDUCER : Depth referred to transducer (initial setting), DBT BELOW SURFACE : Depth referred to surface (waterline), DBS BELOW KEEL : Depth referred to ships keel, DBKSee paragraph 4.3 for details.

Control Mode

The control mode can be changed from/to AUTO/MANUAL by pressing . Theselected mode is indicated here.AUTO=fully automatic control mode MANUAL=manual control mode

NOTE: The AUTO indication just below the zero line near the top of the range scale is turned offinstead of changing to MANUAL when you select the manual control mode.

Zero Line

This (initially red) thick line is caused by a portion of transmitting energy leaking into thereceiver, and its upper edge represents the onscreen position of the transducer face.When the transducer draft (, depth from waterline to transducer) is entered, the zeroline shifts toward the bottom by the amount of the draft. See paragraph 4.2 for details ondraft entry. When the depth reference is set to BELOW KEEL with the correct keeloffset (distance from transducer to keel) entered, the zero line shifts above scale line 0by the amount corresponding to the offset, and its display is suppressed intentionally.See paragraph4.10.8.3 for details.

The presence of the zero line in the strongest color*1, except in the case ofdepthbelowkeel (DBK) reference setting, indicates that both the transmitter and the

receiver are working consistently. *1

See paragraphs 3.4.1 and 4.10.2.

Maximum Range Limit

When the automatic control mode is activated (by pressing ), the maximumrange limit will change automatically so that the bottom echo is always displayed in thescreens lower half area. See paragraph 3.3.2 for details.

Pressing manually selects greater ranges, and pressing, smaller ranges,while activating the manual control (MANUAL ) mode.

Color Scale

This color scale is initially turned off. When the *1echo display is set to show echoes infull colors, the colors used to display various echo strength levels are listed here inorder of relative strength. The color that represents the strongest level is initially red,and the one that represents the weakest level is initially blue. The intervening colors

simulate various mid strength levels. See paragraph 4.10.2 for related information.

An echo must be initially 3 decibels (dB) stronger or weaker than the adjacent strengthlevel before it can be displayed in next stronger or weaker color. See para graph4.10.4 for greater details.

Picture Feed (PF) Rate

Echo picture (echogram) feeds (scrolls) automatically to the left at a rate with passageof time. The feed rate affects the duration of echo display across the screen, and can bechanged in the following steps by repeatedly pressing : PF=1/1: Feeds once every sounding. (fastest feed rate initial setting) PF=1/2: Feeds once every two soundings. PF=1/4: Feeds once every four soundings.The rate of sounding for the range in use is not affected by feed rate selection. Theonscreen time calibration intervals change with the feed rate in use. See fordetails.

3.3. Selecting Depth Ranges

3.3.1. Manual SelectionA total of eight depth ranges are available as illustrated below, and are automatically

selected to display the bottom echo and read depth when the unit is working in theautomatic control (AUTO) mode. In applications where you wish to monitor depth on acertain fixed range scale or where you wish to select range scales manually, switch to themanual control (MANUAL) mode first (by pressing ). The depth range scales can thenbe selected by repeatedly pressing the following pair of keys:

: Selects smaller ranges (in HtoA direction).

: Selects larger ranges ( in AtoH direction).All depth ranges start at scale line zero (0), unless a *1transducer draft or *2keel offset isentered. No phased depth ranges are available.Select depth ranges so that the bottomecho is displayed, preferably within the lower half part of the screen for ease of monitoringthe changing depth graphically. If the depth exceeds the current range limit, abottommissing alarm will be triggered. See paragraph 3.12.3for details.*1Paragraph 4.2 *2Paragraph4.10.8.3.

3.3.2. Automatic Selection (Automatic Mode of Operation)

Pressing will enable the equipment to operate in the fully automatic mode, selecting

depth ranges, adjusting the receiver gain level and *1

TVG level (shallow gain suppressionlevel) all automatically. The bottom echo will always be displayed in the lower half screenarea regardless of changes in depth.

The figure below illustrates an example of how depth range selection occurs with this modeactivated, as you travel over a gradually deepening bottom. As soon as the bottom shows upat the lower end of the scale lines on the current depth range, the next greater range will beautomatically selected. When traveling over a gradually shallowing bottom, the rangeselection sequence is reversed. As soon as the bottom is registered in the upper half screen,the next smaller range will be switched in.

To terminate the function, press again.

*1TVG: Timevaried gain. This function, which sharply reduces the receiver gain at the start of eachsounding and gradually recovers the normal gain level with time, is used to prevent surface clutters andother noiseproducing reflections near the surface from disturbing depth measuring operation.

3.4. Interpreting Echo Display

3.4.1. Bottom Echo in Full Colors

The equipment normally shows only the strongest part of the bottom echo in a single color(initially red). Echoes including the bottom reflection can however be displayed in up to atotal of 7 different colors initially, red, orange, yellow, green, yellowish green, light blue andblue, which represent the various layers of the bottom stratum in order of strength via the*1procedure given in paragraph 4.9. Namely, red represents the strongest level, and blue,the weakest one. A colored bar (termed color scale in this manual) located at the left endof the screen indicates the colors that are currently assigned to display echoes, as in thefigure below.

*1MAIN MENU8:ECHO DISPLAY2:NORMAL DISPLAYYou can change those color assignments by selecting from a total of 10 different colorsprovided. See paragraph 4.10.2 for instructions.

Figure 3-18 Initial Assignments of Bottom Echo Colors

Figure 3-19 Initial Echo Dynamic Range

There is initially an approximately 3 dBdifference in strength between two adjacentcolors, as illustrated in the figure at right,meaning that a particular color is approx. 1.4

times stronger or weaker than either adjacentcolor. This difference, called the echodynamic range, can be changed to suitvarious bottom conditions (hard, soft, muddy,etc.). See paragraph 4.10.4 for instructions.

3.4.2. Multiple Bottom Echoes

When navigating a shallow water area, you may observe a bottomlike echo at twice thepresent depth, and sometimes also at three or four times the depth. This multiple echo

phenomenon occurs when the first echo is reflected back and forth a number of timesbetween the water surface and the bottom like reverberations.

In the case of the example below, a first reflection, which is used to register the depth, isbounced back to the bottom, and then back again to the transducer as a second reflection,thereby causing that echo to be recorded at twice the depth.

The appearance of multiple bottom echoes indicates that the bottom is relatively hard.

Figure 3-20 Multiple Bottom Echo Display Example

The effect of multiple reflections may be reduced by decreasing the receiver gain (throughgain and/or TVG adjustment, paragraphs 3.8 and 3.9) or by reducing transmit power output(paragraph 4.6) when you are operating the unit in the *1manual control (MANUAL ) mode.

Occasionally a large school of fish or a temperature layer can also cause the equipment tolock onto it, thus producing an incorrect digital depth readout.

*1Pressing switches the control between automatic mode and manual mode. When the unit is in theautomatic control ( AUTO) mode, attempting to change the receiver gain or TVG level also changes themode to MANUAL .

Whenever you have any doubt about the validity of digital depth reading, check the depthgraphically against the onscreen scale calibrations to determine whether the current digitalreadout is valid or not. A special caution should be exercised when using digitaldepth information while in shallow water operation because the second echomay be tracked for depth measurement, resulting in a digital readout twice theactual depth.

3.4.3. Other Echoes

When the *1echo display is set to show echoes in full colors, the equipment will show*2echoes from fish schools, temperature layers, and various tiny objects, like plankton

concentrations and air bubbles, in addition to the bottom echo. The figure below is anexample of how such echoes show up on the screen. A thick line appearing in the strongestecho color at the upper edge of the echo display area is called a zero line, which is causedby a portion of transmitted energy leaking into the receiver, and represents the onscreenposition of the transducer. When a transducer draft is entered (paragraph 4.2), the zeroline shifts down from the top scale calibration (scale 0) by the amount of the draft. When akeel offset is entered (paragraph 4.10.8.3), the zero line occurs above scale 0, and itsdisplay is suppressed.

*1Paragraph 4.9. (MAIN MENU8:ECHO DISPLAY2:NORMAL DISPLAY)*2Those echoes are mostly suppressed by TVG with the unit in the automatic control mode .

Figure 3-21 Typical Shallow Water Echo Display Example

< WARNINGS >

1. A LARGE FISH SCHOOL, ESPECIALLY ONE AT SHALLOW DEPTHS, CANOCCASIONALLY PRODUCE AN EXTREMELY STRONG ECHO, CAUSING THEEQUIPMENT TO LOCK ONTO THAT ECHO AS THE BOTTOM. AN INCORRECTDIGITAL READOUT WILL OCCUR AS A RESULT. BE SURE TO CONFIRM THEREADOUT BY COMPARING IT WITH ONSCREEN BOTTOM ECHO LOCATION.TOTAL RELIANCE ON THE DIGITAL DISPLAY IS DANGEROUS AND MUST BEAVOIDED, ESPECIALLY WHEN TRAVELING IN SHALLOW AREAS.

2. WHEN TRAVELING OVER A SHALLOW BOTTOM, THE EQUIPMENT MAYOCCASIONALLY LOCK ONTO THE SECOND BOTTOM ECHO, READING TWICETHE ACTUAL DEPTH. BE SURE TO COMPARE THE BOTTOM ECHO POSITIONWITH THE DIGITAL DEPTH READOUT WHENEVER NAVIGATING SHALLOWWATER AREAS OR WHENEVER THE DIGITAL READOUT IS QUESTIONABLE.SEE PARAGRAPHS 3.4.2 AND 4.6 FOR RELATED INFORMATION.

3.7.2. Selecting Channels (Transducer Frequencies) (continued 2/2)

3.7.2.2. Low Frequency OperationLow frequency (normally 50 kHz) operation uses a wide beam transducer with inherentextended depthpenetrating capability, thereby producing relatively satisfactory resultsunder the following situations:

where good echo sensitivity is required in deep water sounding. where operation takes place in deep water areas ( in excess of 200m) most of the time.

3.8. Indication of Transducer Location

If your echo sounder system has two separate transducers (for channelA and channelB)installed at different locations (middle, fore or aft location in an alongships direction), ashipshaped icon just above the top scale line graphically is provided to indicate the relative

location of the transducer currently in use for sounding, as in the example below.
