WARNING!

USE THIS GPS RECEIVER ONLY AS AN AID TO NAVIGATION. A

CAREFULNAVIGATOR NEVER RELIES ON ONLYONEMETHOD TO

OBTAINPOSITION INFORMATION.

CAUTION

This OPS receiver, (like all GPS navigation equipment) will show the shortest, mostdirectpathtoawaypoint. It provides navigation datatothe

waypoint regardless ofobstructions. Therefore,the prudent navigatorwill

notonlytake advantage ofall availablenavigation toolswhentravellingto awaypoint,butwillalsovisually checktomakecertain aclear,safepath to

PCF OFFSET

TheGPSnavigation system relies oncomplex mathematical calculations to determine your position based on satellite data and otherfactors. One factoristhe Earthsshape. Sincethe Earth isnotatruesphere, variations in thecalculations have tobemadetoaccommodate deviations. Tomake

matters morecomplex, not everyone uses the samedata to determine whatthedeviations are.Thesizeandshape oftheellipsoidsthatareused to approximate the earth'ssurface are improved often. This can lead to errors ifyour navigation device uses one ellipsoid, whileyourchart uses adifferentone.The term used forthese ellipsoids is "Datum."

Toreduce theerrorfactorbetween datum,thisunitgives youthecapability

to moveor "offset" the positionshown onthe display tomatch the one on the chart. Theunitwill add this offset atall times.

Remember, the GPS erroris very dynamic and the PCF offset should never be used in an attempt to cancel the error. In general terms this featureshould only be used ifyourmap indicates whatthepossible error is. Thisfeatureshould always be resetto zero (0) whenfinishedwith that chart.

For example, suppose you are stopped at a locationthat is accurately marked on a chart. Your unit shows a longitude position that is .010

degrees less than the one on the chart. Using the Position Correction Factor (PCF)Offsetfeature,youmake the unitreadthesameasthechart.

INTRODUCTION

The UltraNav II is a high quality, wide screen combination sonar and differntial ready OPSreceiver with performance thatissecondto none in itsclass.Using menufeaturesand "soft-key" operation, the UltraNav II is alsoone oftheeasiest-to-use products thatEagle haseverbuilt.Thewide

"UltravisionTM"screen showsthe underwater worldwith high resolution and detail. The display and night operation.

Installing an optional ST-T speed/temperature sensor, gives digital boat speed, surface watertemperature, and distance travelled(log) displays.

POWER CONNECTIONS

The UltraNav I! works from a twelve-volt batterysystem. For the best

results, attach the power cabledirectly tothe battery. You canattach the power cable to an accessory or power buss, however you may have

problemswithelectrical interference. Therefore, ifssafertogoahead and

attach thepowercabledireotlytothebattery. Ifthecable istooshort,splice #18 gaugewireonto it. Thepowercablehasfourwires; red,black, green, and white. Red is the positivelead, black is negative or ground. Make certaintoattach thein-linefuseholdertothered leadasclosetothepower sourceas possible. Forexample, ifyou havetoextendthepowercableto

thebatteryorpower buss, attach one end ofthe fuse holder directlytothe batteryor power buss.Thiswill protect both theunitandthepowercable in theeventofashort.TheUltraNav II usesa3-ampfuse.Thereisreverse

polarity protection built into the UltraNav II. If the power wires are connectedbackwards, no damage will occurtothe unit.

IMPORTANT!

Thewhite wire is for a NMEA interface. The UltraNavII sends data to

anotherelectronic navigation devices throughthe whitewire.The green wire is for a differential GPS (DGPS) receiver input. If the white and green wires are not used, tape their ends

To connect a device tothe UltraNav'sNMEA output (white wire); attach a two-wire shielded cable fromthe other device'sNMEA intputto the

white andblack wiresontheUltraNav il's cable. Soldertheshield power

to the black wire on the power cable. Do not connectthe shield to the

otherdevice. See theotherinstrument'smanual formorewiring instruc- tions.Use the same procedure toconnectthe DGPS receiversoutputto

the green and black wires on the UltraNav II.

Note: Theshielded wire is not absolutelynecessary, howeverit is best to use it due to the high electrical noiselevels found in today'smarine

environments. To avoidproblems later, we highly suggestthatyou use shielded wires whenever making acommunications connection between two instruments. See the NMEA section in the GPS section

manual for more information.

GPS MODULE INSTALLATION

The GPS thodule can be installed on aflat surface or (withthe supplied

adapter) ona pole. Mountthemodule in anareathat guarantees aclear viewofthe skyat all times. Inorderforthe module to receive thesignals

from the satellites, it must not be obstructed. An ideal location is on a cabinroof, or deck. The gunnels also make a good location. Attaching

Surface Mounting -WithoutAccess

If you don'thaveaccess to the backside ofthe mounting surface,use the "cleats" supplied with the UltraNav II. (Note: This is assuming you can "snake" the module'scableto a locationthat is accessable. A hole will still need to be drilledinthe mounting surface forthe cable.) Using the gasketas atemplate, mark and drill the 17mm (11/16") hole forthe cable. Attach the cableto the module .and dropthe other end of the cablethrough the gasketand down the hole. Place the module on the

gasket. Slide the "cleats" onto each end of the module and (using the cleats as templates) mark four holesfor 5 mm (#10) mounting screws. Drillthe holes, then replace the cleats onthe module andfasten themto

the mounting surface with 5 mm (#10) screws. Route the cableto the UltraNav II.

SELECTNMEA

TheUltraNav II sends data outthewhite wire onthe powercableaccording tostandards set bytheNMEA (NationalMarine Electronics Association). This allows the UltraNav II to send position, depth, and navigation information to"listener" units,suchaschartinginstruments,autopilots, and

othermarine instruments. TheUltraNav II uses thefollowing NMEA data

protocols: NMEA 0180and 0183. NMEA 0180sends steeringinformation only. It'suseful mainly forautopilots. NMEA 0183 sendsdepth, position, steering, speed, and more. Inorderto usethisfeature, thewhitewire on the power cablemustbe connectedto the NMEA datainputon the other

instrument. See theinstallationsection in thefrontofthismanual forwiring connection information.

The UltraNav II also has the	NTLY USING:
