1 Introduction
The SeaScanARCScoutMkII isanembedded side scansonardatacollectionsystemcreatedby Marine
Sonic Technology / ATLAS North America. Itfeatures a fully integrated power supply, DSP processor
transmitter,and receiverall inasingle boardcompactpackage. The ScoutMkII'sDSP boardcontainsa
specializedFPGA basedsignal processingengine andsoftcore processorbasedcontroller.
The ScoutMkIIcommunicates overthe builtin10/100Ethernetport. It also featuresisolatedRS232and
Synchronization IO. The system accepts NMEA 0183V1.5standard datastrings forrecordingof navigation
dataas well as custom NMEA 0183formattedstringsforadditional datasuch as Altitude,Roll andPitch.
2Quick Start (Single Frequency Configuration)
Thissection serves as a how-to for getting yourScout MkII setup and runningquickly. Follow the procedure
below:
1. Before connectingthe input powersupplies tothe ScoutMkII, make sure thatthe input powersupplies
are operatingproperly and withinthe specifiedoperatingparametersforMkII.
2. Check that everythingis connected accordingto the "SeaScan ARC ScoutMkII Installation Guide",
followingthe single frequency installationinstructions. Ataminimumthe inputpowerandnetwork
connections need tobe connected.
3. To verifyproperoperation, connectthe supplied serial connectiontoaserial port(viaDB9to USB
converterordirectconnection) onacomputer. Ensure thatthe console isconnected and thatthe
terminal programon the PCissetto 115.2kbps, 8data bits, no parity, and 1stopbit. Hand shaking
shouldbe turnedoff. The console displaysmany useful start-upand run-time messages.

5.1 Application Settings Page Configuration
The ScoutMkII is configuredthrough the ApplicationSettings webpage. Inthis section we will describe the
individual settings. Anexample ApplicationSettingsweb page is shownbelow.
Clickingthe Save buttonwill submitthe settingsshown onthe page tothe ScoutMkII. The ScoutMkII will
thenstore the settings. The ScoutMkIIwill then displayanew page withthe new settings.
Clickingthe Resetbutton resets the MkII unitand appliesthe settings thatwere saved.
Clickingthe cancel button will reload the previouslysavedand appliedsettings without applyingthe new
settingsto the Scout MkII.
Note: Changingthe application settingsrequiresthe settings tobe savedand resettingthe ScoutMkIIunit
forthe changestotake affect.

Thisis the ScoutMkII's IPV4addresson anetwork. The defaultaddressis 169.254.86.213. This is compatible
with the zeroconfig/autoconfigIP addressrange so the ScoutMkIIcanbe usedoutof the box withmost
computers in apoint-to-pointnetwork configuration.
NetworkMask
Thisis the ScoutMkII's networkmask. The defaultnetwork mask is255.255.0.0.
SDSDestinationAddress
Setthisto the addressofthe device thatthe SDS datastream will be sent to. Settingone ormore of the
loweroctetsto255will allow the SDSUDP/IP packetsto be broadcaston thatsubnet. The example above
showsthatthe Scout MkIIis broadcastingonthe 169.254subnet. The SDSoverUDPportis1409. The
defaultSDS destination address is setto 169.254.255.255.
Note: The Masterand Slave unitsdo NOTrequire different IP addresses.
5.1.2 Sonar Startup Settings
The SonarStartupsettingsdictate the initial settingsforthe sonarhardware onboot.
Range
Thissetting controlsthe sonarsystem's initial slantrange. Its unitsare metersandcanbe setfrom 5to 300
meters. The defaultvalue is30meters.
Note: Inthe dual frequency, 4channel configuration the range iscontrolled bychannels0and 1. Inthe
single frequency, 2channel configurationthe range iscontrolledbychannel 0.
Range Delay
Thissetting controlsthe initial range delay. Range delaysets the range (startingattime 0whendata
collection begins) atwhichthe sonarhardware startssamplingsonardata. Itis an offsetanditsunitsare in
meters. Itcan be setfrom0(noRange Delay) tothe currentRange setting. The defaultvalue is0meters
(noRange Delay).
Note: Inthe dual frequency, 4channel configuration the range delayiscontrolled bychannels0and1. In
the single frequency, 2channel configurationthe range delay is controlledby channel 0.
Channel Settings (Dual Frequency - 4 Channel Operation)
Settingsmaybe adjusted individuallyforeachof the ScoutMkII's 4channelsinthe Dual Frequency
configuration. The channels are dividedinto columns. The channelsare labeledMaster:0, 1andSlave:2, 3.
Channel Enabled
Thissettings enables ordisables the channel.
Channel Bandwidth
The bandwidth settingallows the userto choose aCHIRP bandwidththatthe channel will use for
transmitting and receiving. Thissettingis notavailable inthe SonarControl Panel. Changingthe
bandwidthmayreduce interference issues duringoperation. Please note thatthe across track resolution is
directlyrelatedto the CHIRP bandwidth. The narrowerthe bandwidth the lowerthe across track
resolution. Whenthe bandwidthis changedthe application settingspage will change the resolution
displayed below the bandwidth accordingly.

5.1.3 Sync I/O Settings
The I/O settingscontrol the behaviorof the Sonar's synchronizationhardware. The syncoutputallows
otherdatacollectionsystemsto be synchronizedwith the ScoutMkII'sdatacollectioncycle. The Syncinput
synchronizesthe ScoutMkII's datacollectioncycle withanexternal timingsource suchasanotherSonar
system.
SyncIN Enable
Thissetting enablesthe SyncInput. When the SyncInputisenabledthe ScoutMkII will only pingwhenthe
SyncInpinis high(TTLlevels). The ScoutMkIIwill notping whenthe SyncIn pinislow. Syncin isdisabled
by default.
SyncOUTEnable
Thissettings enables the SyncOutput. Whenthe SyncOutputis enabledthe ScoutMkII will send outaTTL
compatible synchronizationpulse onitsSyncOutpin. The pulse shape is determinedby the pulse length
andpulse decimation settings. The defaultvalue isdisabled.
SyncOUTPulse Length
The pulse lengthsettingcontrolsthe length of the SyncOutputpulse. Itsunits are microsecondsand canbe
setfrom 1to 1000(1ms). The defaultvalue 1000uS (1ms).
SyncPulse Every
Thissetting controlsthe SyncOutputdecimation counter. Itcan be setfrom0to30. A settingof 0will send
one synchronization pulse everyping. A settingof 30will sendone synchronization pulse every30pings.
Thisfeature will allow otherdatacollection systems to synchronize with the ScoutMkII thatdonotwork
well with itshigh pingrates(up to60Hz). The defaultvalue is 1(1pulse every otherping).
SyncOutputActive
The SyncOUTpulse canbe configuredto triggeraseitheranActive High orActive Lowdependingon whatis
requiredby the user's system. The figures belowshowthe differentSyncOutpulses.
