Frequently Asked Questions - PI32 SIMRAD

How do I update the chart data on my Simrad PI32?

You can update charts via a microSD card. Download the latest charts from C-MAP or Navionics, copy to a microSD card, insert into the PI32, and follow the on-screen update instructions. Ensure the device has a stable power supply during update.

Can I use the PI32 with a radar system?

Yes, the PI32 supports radar overlay when connected to a compatible Simrad radar scanner (e.g., HALO series) via Ethernet. You need to enable radar in the settings and configure the overlay.

What should I do if the touchscreen is unresponsive?

First, clean the screen with a soft, dry cloth. Remove any screen protector. If still unresponsive, try rebooting the device by holding the power button for 10 seconds. If the issue persists, contact Simrad support or perform a factory reset (backup data first).

How do I connect my PI32 to a NMEA 2000 network?

Use a NMEA 2000 backbone cable with a drop cable to the PI32's NMEA 2000 port. Ensure proper termination at both ends of the backbone. Power the network via a dedicated NMEA 2000 power cable. The PI32 will autoconfigure to detect devices.

What is the maximum depth the fishfinder can display?

The PI32's fishfinder (with appropriate transducer) can display depths up to 900 meters (2950 feet) depending on transducer frequency and water conditions. For best results, use a 50 kHz frequency for deep water and 200 kHz for shallow.

Can I view my PI32 on a smartphone or tablet?

Yes, via the Simrad GoFree app. Connect the PI32 to your home network via Wi-Fi or Ethernet, then use the GoFree app on a smartphone or tablet to mirror the display and control some functions.

Does the PI32 support AIS reception?

Yes, the PI32 can receive AIS data if connected to an AIS receiver or transponder via NMEA 0183 or NMEA 2000. It displays AIS targets on the chart with collision risk information.

How do I perform a factory reset?

Go to Settings > System > Factory Reset. Confirm the action. Note that this erases all user data including waypoints, routes, and settings. Backup important data to a microSD card before resetting.

What power cable is included with the PI32?

The PI32 includes a 1.5-meter (4.9 feet) power cable with a fuse holder. It terminates in bare wires for connection to a 12-24V DC system. Use a 2-amp fuse (included). Ensure correct polarity: red positive, black negative.

Can I install the PI32 in a location exposed to direct sunlight?

While the PI32 has an IPX6 rating and high-brightness display (1200 nits), prolonged direct sunlight can cause overheating. Install under a sun cover or in a shaded area to maintain optimal performance and lifespan.

The PI32 Catchmonitoringsystem can work with three sensors simultaneously.

Thesensors are powered by built-in rechargeable batteries. They are housed in titanium casings, and designed using advanced shock-absorbing materials. The information collected by the sensors are sent through the watertothe hydrophone by means of coded sound waves. From the hydrophone, the signals are sent to the operator unit, which decode the information, interprets it, and finally present it to you.

Temperature: Toowarmortoocoldwater?

Fishing into warmortoocold water may be just a waste of time and money. Thesame appliestoapelagic trawl placed on the wrong side of a thermall layer. Using advanced technology, rugged construction and award winning design, the PI Temperaturesensor allows you to increase your fishing efficiency.

The PITemperaturesensor tells you the exact seawater temperature while you are fishing.

Thewatertemperatureisanimportantparameter.Fishandbait aretemperaturesensitive,andtheyarenormallyfoundwithin specifictemperaturezonesforfeedingandspawning.

However, the temperature layers in the water are changing constantly, and for this reason the temperature must be monitored constantly. Fishing in an area with unfavourable water temperature might be just a waste of time!

Foranykindoftrawling, usethissensortomonitoring and log the temperature. Then, increase your knowledge about the correlation between temperature, fish concentration and catch efficiency. On apursesinenet, monitorthetemperature to see when you are passing the thermo-cline.

• If you operate at the maximum range of the sensors, you may be able to increase this ranges slightly if you use lower communication channels. This is because the lower communication channels user lower transmission frequencies.

Changingtheupdaterate

Itmayberequiredtochangetheupdaterateonasensor, thatis howoftenitsendsinformationbacktothePI32system. A high updaterate will give frequent information updates, but the sensor will use more battery power. If you need your batteriesto last as long as possible, you must consider lowering the update rate.

• Alowupdaterate will provide you with fewer information updates, but the battery will last very long.

Sensorconfiguration

The TwinSpread and Remotesensors are supplied insets, and they MUST operate in the these sets. Thesets are:

• Twin Spread 1 uses two Remote sensors; Remote 1 and Remote3.
• Twin Spread 2 uses two Remote sensors; Remote 2 and Remote4.

Whensuppliedfromthemanufacturer, all TwinSpreadsensors aresetupasTwinSpread1. If youwishtouseaTwinSpread2, yourdealer(oryourself)mustreconfigurethesensorusing the PIConfiguratorapplication.

Communicationchannelsandupdaterate

EachTwinSpreadsensorwillcommunicateontwochannels, oneforeachofthetwodistancesthesensormeasures. By default, these communication channels are set to 02 and 07.

• Channel 02 is used to measure the distance to Remote 1.
• Channel 07 is used to measure the distance to Remote 3.

Bydefault, both communication channels a resetup with Fast updat rate. In order to increase the lifetime between each sensor charging, you may consider changing to Normal update rate.

If you wishtore configure the settings, your dealer (ory yourself) must us the PIC configurator application.

Placingthesensorsonthetrawl

The TwinSpread sensor must be mounted on the port trawl door, and the three communication transducers on the sensor must not be obstructed. Ensure that you have a clear line of sight between the tip of the Twin Spread sensor and the vessel, and between the Twin Spread sensor and the two Remote sensors.

Remote1isplacedonthecentreclump.

Remote3isplacedonthestarboarddoor.

This configuration will allow the TwinSpread sensor to measure the distance from the port doort the centre clump directly. It will also measure the distance between the two or more indoors. In order to calculate the distance between the centre clump and the star boarddoor, you must perform there required settings on the PI32.

Therecommended sensor configuration to monitor the trawl openingistouse one Heightor Depth sensor on the headrope, and one Depth sensor on the footrope. However, if you only use one of these sensors, place it on the headrope. The PI32 will then manually draw the trawl opening markers for you provided that you enter the typical height of the trawl opening.

The following parameters will provide the e-xtrain information related to trawl markers:

- Headrope and footrope sensors: You need to tell the PI32 whichDepthand/orHeightsensor(s)youhaveplacedonthefootropeand/orheadropeofthetrawl.

- Trawlopeningmode: This parameter decides how the trawl openings shall be created on the graphic presentation. If you have sufficient sensor on the trawl you must select Auto, and the PI32 will automatically calculate the trawl opening and draw it accordingly. If you only have one sensor on the trawl opening (Depthor Heights sensor on the headrope), the Manual setting will add an artificial line on the presentation. The distance from the headropeto the footropemust then be defined manually using the Manual trawl marker parameter.

Changingatransmissionchannel

It may be required to change one more or more transmission channels, and there may be many reasons for this.

- You have more than one of each sensor. For example, if you havethreetemperaturesensors, they MUST communicate on threedifferentchannels.

- OthervesselsnearyourusethesamePI32system(ora similar), and they have one or more of their sensors set up to the same communication channels as you have. This will create interference, as you will "read" each others sensors.

- Ifyoursensorsaresetuptousecommunicationchannelstoo closetoeachother(forexample,youhavechosenchannels 4,5and6),thiswilllimitthevessel'sspeed.Thereasonfor thisisthedopplereffect.Ifthespeedistoohigh,thedoppler willcausethetransmissionfrequenciestochangesomuch thattheyoverlap,andthiswillcreateinterference.ThePI32 willprovideawarningifthisisabouttohappen!Youmust theneitherchangetoothercommunicationchannelsfurther apart,orreducethemaximumshootingspeed.

- If you operate at the maximum range of the sensors, you may be able to increase this ranges slightly if you use lower communication channels. This because the lower communication channels user lower transmission frequencies.

Changingtheupdaterate

Itmayberequiredtochangetheupdaterateonasensor, that is how oftenitsendsinformationback to the PI32 system. A high updaterate will give frequent information updates, but the sensor will use more battery power. If you need your batteriesto last as long as possible, you must consider lowering the update rate.

• Alowupdaterate will provide you with fewer information updates, but the battery will last very long.
• Ahighupdateratewillgiveyoufrequentinformation updates,butthebatterywillrunoutfaster.

SENSOR CHARGERS

Overview

TwodifferentbatterychargerscanbeusedtochargethePIand PSsensors:

• PICharger
• PS30Charger

Event though both chargers can be used to charge any of the sensors (except the PI Height sensor), only the PI Charger will provide fast and intelligent charging of the PIsensors.

Note: ThePIHeightsensorcanonlybechargedwiththePICharger.

Topics

→ PICharger,page145
→ PS30Charger,page147

PI Charger

Purpose

ThePIChargerisanintelligentbatterychargerforfastand securechargingofthePIsensors. Thechargerwill automaticallysetupthecorrectchargingcurrentdependingon thesensortypeandthebatterytemperature.EventhoughthePI ChargerisdesignedforfastchargeofthePIsensors,itcanalso chargethePSsensors,butonlyatnormalchargerate.Afuel metershowsthestatusofthebatteryduringthecharge.

Dailyoperation

1) Attach the charging clamp to the sensor as follows:

Redclamp: Positive fastening lug(+)

Blackclamp: Negative fastening lug(-)

2) Ensure that attachment materials, rope etc. donot short circuit the charginglugs, preventing charging and causing damage to the sensorlugs.

Onceconnected,thechargerwillidentifywhether thesensorconnectedcanbefastchargedornot. Thebatterytemperaturewillalwaysbemonitored forafastchargingsensor.Asensorwhichcannot befastcharged,willnotdisplaythebattery temperature,andthetemperatureLEDwillbe dark.

3) Observethechargetimesandtemperaturelimitations:

Fastcharge: Firstapproximately 1 hour for 70% battery capacity, then approximately 3 hour store each 100% capacity. Once fully charged, a constant trickle chargewill compensate for self discharging. Not that fast charging appliesto PI sensor only!

Normalcharge: 16 hours for full battery capacity. This mode applies for charging outside specified temeparture range, and for all PS sensors.

Chargingtemperature:Forbestresults,keeptheambient temperaturebetween+10and+25°C.Donotchargein temperaturesabove+50°Corbelow0°C!

Toaccesstheparameters, presstheENTbuttonwhenyouhave anechosounderpresentationonthescreen.

(CD11100C)

Rangestart: This is the upper depth from which you wish the echosoundershall start. This value will typically be 0 meters, but you may fore example setup the echosoundert o only present echoes from 5 meters below these as surface and downwards.

Range: This is the vertical depth range for the echosounder. You can set it to changed depth range automatically (AUTO), or you can define your own fixed range. The maximum rangewill depend on the chosenechosounder frequency, asthe 38 or 50 kHz modes will detect echoes deeper than the 200 kHz mode.

Gain: Thisisthegainintheechosounder'spreamplifier. The gainmustbedefinedmanually, and you can choose any value between 1 and 95dB. In most cases, use a value around 30dB. If you set to much gain, the echogram will contain a lot of noise and false echoes.

Whiteline: This parameter allows youtoswitch the Whiteline function on or off. When enabled, abandin the current echogram background colour is inserted immediately below the detected bottom depth.

Expansion window: The PI32 provides a Bottom expansion function. Whenthisisenabled, you can control the depth range in the expanded window using this parameter. To enable the Bottom expansion function, select it on the Echo menu. To disable it, select Echo display on the Echo menu.

TVG(TimeVaryingGain): The PI32 provides a TVG function to enhance the echoes from deeper waters. You can select either Bottom(20logR) or Fish(40logR) setting, depending on which echoes you wish toenhance.

Soundspeed: This parameter allows you to finet the performance of the PI32 echosoundertothespeed of sound in the water. However, in most cases, these speed is not known, and this parameter is not important at all when operating in shallow waters. For all practical purposes, leavethissetting to the default value of 1470 m/s.

Pingtopingfilter: This function employs a filter which compares the echo information from one ping with the information from the previous ping. This will “cleanup” the echogram by removing random noises spikes and interference with no correlation with the previous echo. The function will thus make the echoes appear more stable. You can switch this filter on or off.

Signalthreshold: This is an on/off function. When activated, it will remove the weakest echoes from the screen. The threshold level is automatic. Activate with caution, as it may remove small fish or other weak unidentified echoes from the presentation.

Colourthreshold: This function allows you to choose the number of colourstouse forechogram presentation. By switching this filter on and selecting a colour in the box, all echocolours “below” the chosen colour will not be shown in the echogram. You can thus regard this as an “echo threshold” which will remove the weakest echoes.

Depthgrid: Whenthisfunctionisenabled, thinhorisontaldepth lineswillbeaddedtotheechogramtoeasieridentifythedepth intervals. Whenyouoperatewithagraphicdisplay, thisfunction canalsobeswitchedonandoffintheGraphicsetup.

Scrollspeed: This function control show fast the presentation shall scroll from right to left across the display. By defining this speed you also control the timescale. If you slowdown the scroll speed, you will also increase the time between each echo sounder transmission (ping). If you choose FREEZE the presentation (and also the echosounder transmissions) will stop altogether. Not that this parameter can also be set in the

Graphicsetup.

Echosounderfrequency: This function allows you to choose echosounderoperating frequency. Use the high frequency for shallow waters, and the low frequency for deeper waters.

Toaccessdialogue, press the MENU button to access the main menu. Then, select Echo sounder setup on the Echo menu.

Notethatthepresentationparametersaredefinedinaseparate dialogue;thePresentationsetup.

Echo sounder setup:

Transducer depth below surface:	0.0 m
Keel depth below surface:	0.0 m
Display:	DEPTH BELOW KEEL
Alarm for fish, strength:	30dB OFF
Depth for fish: min:0010m max:0100m

(CO11000)

Transducerdepthbelowsurface: Entertheverticaldistance between the transducerface and the watersurface. Normally, this value can be fixed, but if tichanges considerably when the vessel is loaded, you may need to change it. The value is used to provide you with a correct depth under the keel (DK) value in the echosounder presentation.

Keeldepthbelowsurface: Entertheverticaldistancebetween thekeelandthewatersurface. Normally, thisvaluecanbe fixed, butifitchangesconsiderablywhenthevesselisloaded, youmayneedtochangeit. Thisparameterisusedtoprovide youwiththecorrectdepthbelowkeelvalueintheechosounder presentation.

Display: This parameter defines which depth valuetobe provided in the echosounder presentation. You can choose to seethewater depth under the keel, the depth below the transducer, orthedepth from these as surface. In order to ensure correct depth readouts, you must make sure that the distances between the surface and the transducer face and the surface and the lower part of the keel are defined. Seethe parameter descriptions above.

Alarmforfish, strength: This parameter enables the fish detection alarm, and adjust the sensitivity (strength). With high sensitivity, smaller fish (with weakerechoes) will trigger the alarm.

Depthforfish: This parameter allows y outo define a vertical depth area (between a maximum and a minimum depth) in which the fish alarm can be triggered. Echoes outside the chosen are will not trigger the alarm.

Depthalarm(minimumandmaximumvalues): This parameter enables an alarm to soundoff the water depth shall lower or deeper than wopredefined limits.

Transmitter: This parameter allows you to obtain the power output from the echosounder. You can choose OFF (and no echogram will appear!), LOW, HIGH or AUTO. In most cases, select AUTO. The echosounder will then automatically adjust the power output depending on the current operational frequency and the current depth.

Transmitpulselength: This parameter allows you to choose the length of the echosounders and transmissions. You can choose OFF (to observ the ambient seanoise), SHORT, MEDIUM, LONG or AUTO. In most cases, select AUTO. The PI32 will then automatically choose the pulselength depending on your current depth range. If you choose to try a manual mode, try long pulselengths when you operate in deeper waters, and shorter pulses with higher frequency in shallower waters. As a general rule, short pulse tesservetomakethe echoes from various objects more distinct. It is therefore used to obtain optimal vertical resolution, as it will separate individual fishes from each other and from the bottom. Longer pulses will penetrate deeper, but with less resolution.

Echosoundermode: This parameter allows you to our the echo sounderina “demonstration” mode, ortoswitchitoff. When you select any other modethan NORMAL, the echosounder will automatically use a “demotransducer” to avoid damage to the output circuitry.

Display: This parameter defines which depth value to be provided in the echosound presentation. You can choose to seethewater depth under the keel, the depth below the transducer, orthedepth from these as surface. In order to ensure correct depth readouts, you must make sure that the distances between the surface and the transducer face and the surface and the lower part of the keel are defined.

Background

BymeansoftheconnectorsontherearsideofthePI32cabinet, itcancommunicatewithseveralperipheraldevices. This is useful, as it allows you to export and import information to and from these devices. In order to establish this communication, the devices one each end of the cable must speak the same “language”. The National Marine Electronics Association (NMEA) has defined communication standards for maritime electron equipment, and the PI32 system conform to these standards. Themost common standard is NMEA 0183, and the National Marine Electronics Association describes it as follows: “The NMEA 0183 Interface Standard defines electrical signal requirements, data transmission protocol and time, and specific sentence formats fora 4800-baud serial database. Each bus may have only on a talker but many listeners.” Form more information about the National Marine Electronics Association and the NMEA 0183 standard, referto the organization’s web pages at www.nmea.org.

Catch/BottomSensorfilter: This filter is used to smooth out the information from the Catch and Bottom Contact sensors. When the filter is switched off any change in sensor status will immediately be shown on the display. Set to LIGHT the change in status must last and remain stable for least twopings before the display is changed. When HEAVY filtering is applied the change in status must last and remain stable for at least four pings before the change is shown on the PI32 display.

AGC(AutomaticGainControl): This function allows the PI32 to automatically control there receive vergain. The units reads and interpret these received signal strength, and adjust the gain accordingly. During normal operation, ONisthere recommended (and default) setting.

Manualgain: If you decide to switch the AG Coff you must set the gain manually. This can be useful when you work at maximum detection ranges with favourable noise levels. The default setting is 0dB, and you can adjust the gain in steps of 20dB.

Multipathfilter(MPfilter): When you operate in an areas with substantial reverberation duetobottom topography, or in shallow waters, you may experience problems when consecutive operating channels have been configured, but the corresponding sensors are not in use. False signals and sporadic error values can also be caused by other types of hydroacoustic equipment operating on the PI32 frequency range. This filter has been implemented to remedy for such interference problem. Default setting is OFF.

Multipathfilterlevel(MPfilterlevel): WhentheMultipath filterhas been enabled, you can adjust the filter level in small step to correct the interference problem. Lower filter values represent stronger filtering. It is best to experiment with this parameter by reducing the value in step of 3dB until the

DetectionThreshold(DT): This function will inhibit reception of the weakest signals. If you experience problems with interferences, signal generating fals data and all of the configured sensors are operative (analogous with the Multipath problem); increase the Detection Threshold value carefully in step of 1 dB. High values allow only strong sensors signal to be detected. Alower threshold value will provide greater range if conditions are optimal, but if toolow, interference will be detected. It is best to experiment with different value to determine which to employ.

Note: If the Detection Threshold (DT) value is set higher than 28 dB, all signals will be prevented from being detected.

Changing a transmission channel

It may be required to change one more or more transmission channels, and there may be many reasons for this.

• You have more than one of each sensor. For example, if you havethreetemperaturesensors, they MUST communicate on threedifferentchannels.
• OthervesselsnearyourusethesamePICconfiguratorsystem (orasimilar), and they have one or more of their sensors set up to the same communication channels as you have. This will create interference, as you will "read" each others sensors.
• Ifyoursensorsaresetuptousecommunicationchannelstoo closetoeachother(forexample,youhavechosenchannels 4,5and6),thiswilllimitthevessel'sspeed.Thereasonfor thisisthedopplereffect.If thespeedistoohigh,thedoppler willcausethetransmissionfrequenciestochangesomuch thattheyoverlap,andthiswillcreateinterference.ThePI Configuratorwillprovideawarningifthisisaboutto happen!Youmusttheneitherchangetoothercommunication channelsfurtherapart,orreducethemaximumshooting speed.
• If you operate at the maximum range of the sensors, you may be able to increase this ranges slightly if you use lower communication channels. This is because the lower communication channels user lower transmission frequencies.

3Usingamultimeter,checktheDCcurrentbetweenthe negativecharginglug(A)andthewaterdetector(B).

-Withtheinitialseawaterswitchandaafullycharged battery, thecurrentshouldnotexceed150μA.
-Witharedesignedseawaterswitch(sacrificialbolt) andaafullychargedbattery, thecurrentshouldnot exceed67μA.
-Ifyoumeasure0μA, checkthefuseonyour multimeter.

Testing on land

1ConnectthePIServiceHydrophonetothePIOperator Unit.
2Placethesensoronalevelsurfacewithits“domedtop” pointingtowardsthetesthydrophoneapproximatelyfive metersaway.
3 Use the Status display on the PI to monitor the sensor's signalstrength.

-If the interference filter is on, the spectrum displayed should be relatively flat (approximately 25dB, interference filters at level 9) with a peak detected in the configured channel.

4 Check that the PI's displayed temperature corresponds with the actual ambient temperature.

Testing in water

1DisconnectthePIServicehydrophone, and reconnect the vessel's normal hull mounted hydrophone.

2Switchoffthevessel'sechosounders,sonarsandother hydroacousticalequipmenttoavoidinterference.

3Lowerthesensoroverthesideofthevessel.

4Lowerthewaterproofthermometeroverthesideofthe vessel, and keepitasclosetothesensoraspossible.

5SwitchoffthePIsystem'sinterferencefilter,andobserve thenumericdisplay.

-If the interferences symbol is not ____ displayed, leave the interference filters switched off to increase the system's range and performance.

Note: Shouldanyproblemsariseduringthisprocedure, check that the communicationchannelandupdateratehasbeenconfigured correctly.

6CheckthatthePIsystem'sdisplayedtemperature correspondswiththevaluefromthereference thermometer.
