History V1 10/30/17 V2 V3 First release | 5 Door Sensors | V1 | Introduction and Presentation Introduction and Presentation Tip: Click Marport logo at the bottom of pages to come back to the table of contents. Introduction Door sensor family includes two types of sensors: Spread Sensor and Door Sounder. Spread Sensors are placed on starboard and port doors and clump in order to monitor the spread of your trawl doors. They communicate with each other via an acoustic link. The Master sensor on the port door communicates with the Starboard and Clump sensors, then sends distance data to the vessel. Sensors also monitor pitch and roll, water temperature and depth. This gives you a full picture of each door's performance. For example, you can know if one of the doors falls flat during a tow or if doors are crossing over each other. Spread sensors can be installed on all types of trawling that use doors. Spread sensors also exist in smaller size to meet the needs of smaller trawlers: a mini Spread (stubby bottle) with a standard or slim housing. Door Sounder sensor displays an echogram presentation and communicates with the vessel through our narrow band protocol. Door Sounder sensors can be installed on both doors. They are here to check that there is a steady distance between the door shoes and seabed. The latest generation is Door Sounder with target strength calibration: sensors are calibrated to all display the same colors for a given target. | 6 Door Sensors | V1 | Introduction and Presentation Applications Here are some examples of data received from Spread Sensors and Door Sounder sensors displayed in Scala. Single Trawl · Master and Starboard Spread Sensors · Door Sounder sensors on both doors | 7 Door Sensors | V1 | Introduction and Presentation Twin Trawls with Triple Distance Master, Clump and Starboard Spread Sensors with triple distance option. Distances from Port door to Starboard door, Port door to Clump and Clump to Starboard door are displayed. | 8 Door Sensors | V1 | Introduction and Presentation Safety Guidelines Important: To ensure proper and safe use of this equipment, carefully read and follow the instructions in this manual.

About Spread Sensors You can use Spread sensors in three different modes: single trawl, twin trawls with double distance and twin trawls with triple distance. The following schemas illustrate the three modes and how Spread sensors communicate with each others. Single Trawl Asks for answer Answers Sends data (spread distance, bearing, pitch and roll, depth...) to the receiver · The master sensor interrogates the starboard sensor to know the distance between them. Then, it sends the distance to the receiver. | 9 Door Sensors | V1 | Introduction and Presentation · Both sensors send data such as bearing, temperature, depth, pitch and roll to the receiver. Twin Trawls Twin trawls with double distance: Asks for answer Answers Sends data (spread distance, bearing, pitch and roll, depth...) to the receiver · The master sensor interrogates the clump and the starboard to know the distance with each one. Then, it sends the distances master-clump (1) and master-starboard (2) to the receiver. · All sensors send data such as bearing, temperature, depth, pitch and roll to the receiver. Twin trawls with triple distance: Asks for answer Answers Sends data (spread distance, bearing, pitch and roll, depth...) to the receiver | 10 Door Sensors | V1 | Introduction and Presentation · The master sensor interrogates the clump and the starboard to know the distance with each one. Then, it sends the distances master-clump (1) and master-starboard (2) to the receiver. · The clump sensor interrogates the starboard to know the distance between them. Then, it sends the distance clump-starboard (3) to the receiver. · All sensors send data such as bearing, temperature, depth, pitch and roll to the receiver. Dual Trawls If you use two separate trawls, you need to install two sets of spread sensors. You can install them in two different ways: in the same way as for a single trawl on each trawl, or if you want to have the distance between the two inner doors, you can set up the following installation: Asks for answer Answers Sends data (spread distance, bearing, pitch and roll, depth...) to the receiver The port trawl uses sensors with triple distance and the starboard trawl sensors with single distance. · The master sensor on the port trawl interrogates the clump (port trawl) and the starboard on the starboard trawl to know the distance with each one. Then, it sends the distances master-clump (1) and master-starboard (2) to the receiver. · The clump sensor (port trawl) interrogates the starboard sensor (starboard trawl) to know the distance between them. Then, it sends the distance clump-starboard (3) to the receiver. · The master sensor on the starboard trawl interrogates the starboard sensor (starboard trawl) to know the distance between them. Then, it sends the distance to the receiver. · All sensors send data such as bearing, temperature, depth, pitch and roll to the receiver. Note: Make sure to put different ranging frequencies between the two sets of Spread sensors. | 11 Description Technical Specifications Spread Sensor Uplink frequency Range to vessel Depth range Depth resolution Pitch angle Roll angle Pitch & roll accuracy Temp measurement range Temp accuracy Data update rate (telegrams) Weight in air Weight in water Mini Spread Sensor weight in air Mini Spread Sensor weight in water Typical battery life Battery type Charging time Warranty Door Sensors | V1 | Introduction and Presentation 30-60 kHz up to 2500 m* up to 1800 m 0.1 m with 0.1% accuracy ±90° ±90° ±0.1° -5° C to +25° C ±0.1° C Spread: 3-15 sec.

Flashing red Flashing green | 16 Door Sensors | V1 | Introduction and Presentation Firmware Spread Sensors Firmware for Spread Sensors depends on your type of trawl and on the distances they measure. About Spread Sensor Firmware There are two generations of Spread Sensor firmware. The first generation (V1) measures one or two distances and the second generation (V2) measures one, two or three distances, with an improved communication link. Important: Do not mix V1 and V2 Spread Sensor firmware on a same installation or the sensors will not be able to send the spread distance. Important: V2 can only be installed on A1 PCBA with rev7 or higher. If using a single trawl you need: · V1 or V2 firmware with single distance measurement. · A Master firmware for the Master Spread Sensor. · A Slave firmware for the Starboard Spread Sensor. If using twin trawls you need: · V1 firmware with dual distance measurement or V2 firmware with dual or triple distance measurement. · A Master firmware for the Master Spread Sensor. · A Slave firmware for the Starboard Spread Sensor. · A second Slave firmware for the Clump Spread Sensor. If using dual trawls you need two sets of sensors, one set of sensors for a single trawl installation and one set of sensors for twin trawls with triple distance (see About Spread Sensors on page 9 for illustration). | 17 Door Sensors | V1 | Introduction and Presentation Single Trawl Master Spread Sensor Firmware Name Spread Master (single distance/single trawl) Spread Master with depth (single distance/single trawl) Spread Master with depth and temp (single distance/single trawl) Spread Master with pitch and roll (single distance/single trawl) Spread Master with pitch, roll and depth (single distance/ single trawl) Spread Master with pitch, roll and temp (single distance/ single trawl) Spread Master with pitch, roll, depth and temp (single distance/single trawl) Spread Master with temp (single distance/single trawl) Spread Master PI (Single distance)* Spread Master PI (Single distance) with depth PI* Starboard Spread Sensor Firmware Name Spread Slave (single trawl) Spread Slave with depth (single trawl) Spread Slave with depth and temp (single trawl) Spread Slave with pitch and roll (single trawl) Spread Slave with pitch, roll and depth (single trawl) Spread Slave with pitch, roll and temp (single trawl) Spread Slave with pitch, roll, depth and temp (single trawl) Spread Slave with temp (single trawl) Spread Slave PI* Spread Slave PI with depth PI* *Compatible with Simrad PI receivers.

Door Sensors | V1 | Sensor Configuration What to do next You can now configure the sensor settings. Spread Sensor Specific Settings Defining the Trawl Geometry If you have firmware for twin trawls, you need to define for the Master Spread Sensor the type of trawl that you are using. About this task Configure the trawl geometry only if you have firmware for twin trawls. Firmware for twin trawls can be used for single trawl and twin trawls. Procedure 1. Connect the Master sensor to Mosa. 2. Click the tab Spread. 3. From Trawl Geometry, select your type of trawl, depending if you are fishing with twin trawls or a single trawl. Defining the Starboard and Clump Sensor Type You need to define the type of Starboard and Clump (if applicable) sensors that are installed. About this task If you have a Starboard and a Clump sensor, you need to do this task for both of them. Procedure 1. Connect the Starboard or Clump sensor to Mosa. | 24 Door Sensors | V1 | Sensor Configuration 2. Click the tab Spread. 3. From Slave Sensor Type, choose according to your type of installation: · Single Trawl: Sensor Slave Sensor Type Starboard Starboard for single/double distances doorspread · Twin trawls with double distance: Sensor Slave Sensor Type Starboard Starboard for single/double distances doorspread Clump Clump for double distances doorspread · Twin trawls with triple distance: Sensor Slave Sensor Type Starboard Starboard for triple distances doorspread Clump Clump for triple distances doorspread Configuring Spread Sensor Telegrams You need to configure telegrams sent by the Master, Starboard and Clump (if applicable) sensors. Before you begin The sensor is connected to Mosa. About this task You need to configure telegrams for each door sensor that you have. Telegrams are used to define the acoustic communication between the sensor and the receiver. Data (e.g. temperature, pitch) are recognized by the receiver according to the type of telegram defined (e.g. TL, CL). The telegram defines intervals between pulses emitted by the sensor, and one interval represents one value. For example, if the interval between 2 pulses of an AL spread telegram is 15 s., the spread is 250 meters. The temperature, depth, pitch and roll options that are displayed on Mosa depend on the firmware installed. Important: Make sure there is a minimum distance of 100 Hz between PRP telegrams and of 400 Hz with the uplink frequency of NBTE sensors. See Appendix A: Frequency Plan on page 73 for a full list of boat/channel codes. Remember: Always click Apply after you changed a setting. Note: To use Spread sensors with a Scanmar system, use AL and AL6 spread telegrams. Temperature, depth, pitch and roll telegrams are all compatible. | 25 Door Sensors | V1 | Sensor Configuration Spread You need to configure spread telegrams sent by the Master sensor to the vessel and, if applicable, by the Clump sensor. You do not need to configure spread telegrams for a Starboard sensor.

If you have a V1 firmware on a bottle produced after S/N 3636606, the connector on the A1 board must be manually changed. Procedure 1. For V2 firmware, click the tab Channel. 2. For a Master, Starboard and Clump sensor, from Select Channel, select Channel Up. 3. If you have a V1 firmware on a bottle produced after S/N 3636606, qualified Marport technicians need to open the bottle and connect the down cable to the up connector on the A1 board and up cable to the down connector. | 29 Door Sensors | V1 | Sensor Configuration Calibrating the Pitch and Roll You need to calibrate the pitch and roll of the sensors when they are placed in the sensor pockets. Before you begin Some trawl door manufacturers measure the pitch and roll offsets themselves and write it on the doors. Check on trawl doors. About this task The sensor pocket is usually welded to the door at a 15 to 20 degree vertical angle. This means that when trawl doors are vertical, the sensors will already have a pitch angle and maybe a roll angle. You need to calculate these angles and offset them in order to have 0° of pitch and roll when doors are vertical. If you do not know the pitch and roll offsets, doors need to be taken out and placed on the ground in order to calibrate the pitch and roll. Procedure 1. If you already know the pitch and roll offsets, go straight to step 4. 2. Prepare the doors: a) Remove all rigging, shackles and attachment points from the doors. b) Remove the net gear attached to the door. c) Using a crane or forklift, place the door on a flat surface, such as a dock or similar location. d) Using the necessary rigging, hang doors with angles as close to 0 degree as possible on the vertical and horizontal plane. Use a carpenter level to help you. 3. Insert the sensor in the pockets on the doors. 4. Open Mosa software. 5. Activate and deactivate the water-switch to connect the sensor to Mosa via Bluetooth. Troubleshooting: If you have difficulty to connect the sensor to Mosa via Bluetooth, remove the sensor from the door, establish the connection, then put the sensor back in the door. To extend the Bluetooth range, you can use a Bluetooth key (ref. TRENDnet TBW-106UB) with a USB extender connected to the computer. Place the Bluetooth key as close as possible to the sensor. | 30 Door Sensors | V1 | Sensor Configuration 6. Click the tab Pitch and Roll. 7. Click Pitch and Roll Calibration, then: a) If you already know the pitch and roll offsets, select Manual, then manually enter the pitch and roll offsets. b) If you do not know the pitch and roll offsets, click Auto Calibrate. Pitch and roll offset values change according to the position of the sensor on the door. 8. Click Save. 9. From Opening Angle, enter the angle between the door and the sensor (horizontal plane) in degrees. If you do not know the angle, ask the manufacturer for the angle of attack. If you cannot know the angle, you can put 35° but be aware that a wrong angle impacts pitch and roll measurements. 10. Click Apply. | 31 Door Sensors | V1 | Sensor Configuration Door Sounder Specific Settings Configuring the Uplink and Down Settings You can configure different settings for uplink and down soundings. Before you begin The sensor is connected to Mosa. About this task Remember: Always click Apply after you change a setting and make sure there is a green check mark . Procedure 1. Click the tab Trawl Explorer. 2. For Door Sounder with target strength only: from NBTE Setup Options you can select Down 1 + Down 2 if you want to compare two different settings on soundings (for example 2 ping lengths or 2 frequencies). The sensor will send two consecutive pings toward down direction. 3. From Down Sounding Range, select the range according to how many meters you want to see under the sensor. Note: The range influences the display of echogram images. When the range is short, data can arrive quicker, which gives better quality images. But the bigger the range is, the lesser the image quality is, because data arrives slower. Note: For Door Sounder with target strength calibration the sounding range automatically changes to 20 meters if the distance to the bottom becomes lower than 20 meters and if you entered a trawl opening lower than 20 m. This way, the echogram displays better quality images when the distance to the bottom is smaller. This is the autorange feature. Important: This parameter must be the same in the sensor settings in Scala. | 32 Door Sensors | V1 | Sensor Configuration 4. From Ping Down Length, enter a pulse length. Pulse length depends on the distance at which you need to detect the bottom (the longer the pulse, the further you can see, but with a lower resolution): · Detection between 20 cm and 2 m, enter 0.1 ms · Detection between 50 cm and 160 m, enter 0.4 ms (maximum detection depth depends on ping frequency and type of bottom. The lower the ping frequency is, the longer the detection depth is). Note: Ping length is an important setting for the calibration of the sensor. If you change the ping length on a sensor calibrated for target strength, you need to calibrate the sensor again. 5. From Ping Down Frequency, enter the frequency for the down sounding. Make sure to put a minimum distance of 20kHz between starboard and clump frequencies. Important: Frequency needs to be between 120-210 kHz for a Door Sounder. Important: If you change ping frequency on a sensor calibrated for target strength, you need to calibrate the sensor again because ping frequency is an important setting for the calibration of the sensor. 6. From TE Uplink Frequency, enter a frequency for the uplink (signal toward the vessel). Important: This parameter must be the same in the sensor settings in Scala. 7. Door Sounder with target strength calibration: from Trawl Opening, enter 0. The opening needs to be lower than 20 to have the autorange feature but otherwise this setting is not useful for a door sensor. | 33 Door Sensors | V1 | Sensor Configuration 8. From TVG Down, select the appropriate TVG (Time Variable Gain) mode. Figure 4: TVG parameters for Door Sounder with target strength calibration Figure 5: TVG parameters for Door Sounder V1 Note: Signals sent by the sensor are attenuated in the water. It means the deeper the target is, the more attenuated signals will be received and sent back. TVG (time variable gain) is here to compensate this effect by using a lower gain level when signals travel toward a target at a small distance and higher gain level when signals travel toward deeper targets. The end result is to compensate sounding attenuation and therefore to show a same target strength for a same target at different depths. For a Door Sounder with target strength calibration, select 20 log to have a better target strength for the bottom. For a Door Sounder V1: · From TVG Coefficient, enter 0.500 to have a better target strength for the bottom. · From Attenuator Coefficient, enter 25. · Leave VCO Coefficient default settings at 3. | 34 Door Sensors | V1 | Sensor Configuration Configuring the Uplink Power You can increase the uplink power of the sensor to increase the power of the signal transmitted. It is useful if you have interferences or if the sensor is far from the vessel. Before you begin The sensor is connected to Mosa. Procedure 1. From Mosa, click the tab General. 2. From Uplink Power Adjustment Level, choose the uplink power (percentage is for Mosa 01.02.00 version and later): Sensor Spread Sensor Door Sounder Recommended Uplink Powers 1800 / 43% 4095 / 100% 1000 / 32% 1800 / 58% Conditions Battery Life Works for most conditions. approx. 11 to 16 days (8 days for a Mini Spread Sensor)* · Sensor is far from approx. 4 days (2 vessel (e.g. high depth) days for a Mini · High level of Spread Sensor) interferences · Issues receiving data · Low SNR Works for most conditions. 60-75 hours · Sensor is far from 30-40 hours vessel (e.g. high depth) · High level of interferences · Issues receiving data · Low SNR *Starboard sensor usually has a longer battery life than a Master sensor (1-2 additional days).

Read this section to know the guidelines regarding the installation of hydrophones on the vessel for purse seining and trawling. Installation Principles Carefully read these installation principles before installing sensor pockets. Angle of Attack The angle of attack is the angle of the door in relation to the towing direction. This angle is important for the efficiency of the doors. It varies between trawl door models, refer to manufacturer to know the exact angle. The angle is usually from 25° to 40°. Opening and Elevation Angles for Spread Sensors The opening and elevation angles depend on the pocket installation on the door. The opening angle is the horizontal angle of the pocket in relation to the door. It should be between 25° and 40°. Opening angles should be in line with the angle of attack. You need to indicate the opening angle on Mosa. | 54 Door Sensors | V1 | Installation The elevation angle, or tilt angle, is the vertical angle of the pocket in relation to the door. It should be between 15° and 20°. The sensor must point toward the vessel: adjust the elevation angle based on the operational depth of the door during fishing operations. Angles for Door Sounder Sensors For Door Sounder sensors, the down sounder must have an angle of 25° in relation to the door. If not, the door will disturb the signal. Adjust the elevation angle so that the sensor | 55 Door Sensors | V1 | Installation points toward the vessel during operation. For bottom trawling, install sensors on the lower part of doors. Communication Spread Sensors communicate with each other and with the receiver. Lines of communication between them and toward the receiver must be unobstructed. The beamwidth toward the receiver (uplink ping) is 46° and beamwidth toward the other sensors (down ping) is 26°. This beamwidth is thinner: this is why it is important to keep sensors aligned. Door Sounder sensors do not communicate with each other, so only lines of communication toward the receiver and bottom must be unobstructed. | 56 Door Sensors | V1 | Installation Installing Sensor Pockets You need to install pockets on each trawl door to hold the door sensors. Before you begin · Read Installation Principles on page 54 to become familiar with installation requirements. · You need different pockets depending on your type of door sensor: · Spread Sensor / Door Sounder (XL bottle) · Mini Spread Sensor (stubby bottle) · Mini Spread Sensor (stubby bottle) with slim housing See Appendix C: Pocket Drawings on page 76 to know which installation you need. About this task Important: Make sure you install the sensor pockets in accordance with the installation principles: pockets are important for the correct functioning of the sensors. If they are misaligned or if the pocket hides the sensor signal, you will have issues receiving data. Important: Take care to gather as much information as possible from the trawl doors manufacturer before installation. Such as the angle of attack and towing angle. Note: If your door model have the doors rigged "nose up" or "nose down", you need to change the angle of the door pockets so that the sensor always point toward the bottom of the ship when being towed. Figure 6: Nose down (left) and nose up (right) Note: If you use Spread sensors for bottom trawling, install pockets on the upper part of trawl doors. Make sure its position does not influence too much the center of gravity of the door. Refer to door manufacturer for details. Procedure 1. Use drawings of door pockets to mark the shape to be cut off: Appendix C: Pocket Drawings on page 76. Note: Ask your local Marport Office for scaled templates of door pockets. | 57 2. Cut round openings in the doors. Door Sensors | V1 | Installation 3. Place the sensor pocket with the bottom portion sticking out of back side of the door. Adjust accordingly to the elevation angle and angle of attack you need (see Pocket Elevation Angle on page 76). Picture above shows angles of attack seen from above the door. 4. You can trace a line with a marker around the pocket at the point it enters the door to remember the correct position. 5. To check if angles are correct: a) Weld only a few points on two sides of the pocket to hold it on the door. b) Place the sensor inside the pocket: slide the sensor on the alignment bar inside the door pocket. | 58 Door Sensors | V1 | Installation c) Open Mosa software. d) Activate and deactivate the water-switch to connect the sensor to Mosa via Bluetooth. e) From Mosa, click the tab Pitch and Roll. f) Click Pitch and Roll Calibration then click Auto Calibrate. Pitch and roll offset values change according to the position of the sensor on the door. Pitch should be between 15 and 20°, roll should be ±5°. Roll may need to be higher depending on the door model and operation: adjust accordingly. g) If you do not have Mosa software, manually check the angles. 6. If values are not correct, move the pocket, then check again. 7. If values are correct, permanently weld the pocket to the door. 8. We recommend to use a protective cage made of metal bars around pockets to protect sensors, like the examples below. Note: Make sure there is sufficient space between the protective cage and the sensor pocket, so that if the cage becomes bent, you can still remove the sensor. | 59 Door Sensors | V1 | Installation Installing Spread Sensors Before you begin To install Spread sensors on the doors, you need to have specifically designed sensor pockets welded to the trawl doors. See Installing Sensor Pockets on page 57. About this task Usually, sensors pockets welded to the doors have a 15 to 20° degree vertical angle. Single Trawl Before you begin For a single trawl you need: · A Master Spread sensor · A Slave Spread sensor Procedure 1. Remove the screw holding the pocket cover. 2. Install the Master sensor (red marker) on the port door and the Starboard sensor (green marker) on the starboard door. 3.

Before charging the sensor: wash with fresh water and dry the sensor. This prevent corrosion of the charging pins. 2. Place the sensor and charger in a dry room like the deck or bridge. The optimal temperature while charging is between 10 and 25 °C. 3. Place the sensor away from any installing material (e.g. wet ropes) and fix the sensor with brackets to keep it stable while charging. 4. Allow good air circulation around the charger for cooling. 5. Connect the 3-pin charging connector to the sensor shoulder bolts. Tip: You can apply a small film of electrical contact grease lubricant on pins. To maintain the electrical pins, polish them with fine sandpaper. Important: Check that the shoulder bolts are not damaged. If they are, contact your local Marport dealer for replacement. Below is an example of shoulder bolts damaged because of insufficient maintenance. 6. Plug in the charger to a 110-240 V AC 50-60 Hz socket. 7. If you have the multi-charger, turn the power switch to the ON position. The power switch lights on. If not, check the AC power cord connection. 8. Wait for the battery to charge: standard charging cycle takes 8 to 12 hours. A fast charge configuration allows a 70 % charge in 1 hour and full charge in 4 hours. 9. Look at the LED(s) on the charger box to know the charge status. For the multi- charger, there is a LED for each sensor charging cable. The charge status are: · Green LED: > 90% · Orange LED: from 70% to 90% · Red LED: < 70% | 65 Door Sensors | V1 | Servicing and Maintenance Results Once charged, the operational life time can be up to approximately 16 days for a Spread Sensor (8 days for a mini Spread Sensor) and 75 hours for Door Sounder sensors. The operational life time depends especially on the uplink power of the sensor, but also on the sensor settings (e.g. sounding range, uplink frequency, options). Maintenance Only an approved Marport dealer can access the internal unit. Warranty will become void if anyone other than an approved dealer tries to do internal maintenance duties on the sensor. CAUTION: Never remove shoulder bolts directly from the end cap (black part). Shoulder bolts are attached to cables and trying to remove them will damage the cables. CAUTION: Always inspect and correctly install all the o-ring seals inside the sensor when doing internal maintenance duties. If o-ring seals are worn out, missing or incorrectly installed, sensor may be flooded. Cleaning the Sensor Wash the sensor with fresh water before you charge or store it. Regularly check that the sensor is clean. If not: · Remove any marine life with a piece of wood or screwdriver. · Wash away mud or debris with warm water. CAUTION: Do not use highly abrasive materials or jet wash. CAUTION: Special care should be taken with sensors and components sensitive to mechanical shock or contamination. | 66 Door Sensors | V1 | Servicing and Maintenance Maintenance Checklist We recommend you to follow this maintenance schedule for better performance and to avoid any trouble with the equipment. Before use After use Between uses Every 2 years · Check that all attachment equipment are not worn or torn. Replace when appropriate. · Check that the sensor is clean. See Cleaning the Sensor on page 66 for cleaning procedures. Wash the sensor with fresh water. · When the sensor is not in use, store in a dry area, without humidity, at a temperature between -10° and 70 °C (14 to 158 °F). · If you put the sensor into storage for a long period of time, charge it once in a while. If you do not, batteries can become inoperable. Return the sensor to an approved Marport dealer for inspection and maintenance. | 67 Door Sensors | V1 | Servicing and Maintenance Troubleshooting Mosa does not start due to error message Mosa displays an error message saying Mosa cannot be opened. Your Mac security preferences do not allow you to open software not downloaded from the App Store. 1. From the upper left corner of the screen, click Apple menu > System Preferences > Security & Privacy. 2. From the lower left corner of the Security & Privacy dialog box, click the lock icon and enter your password (if applicable). 3. At Allow apps downloaded from, select Anywhere. 4. For some macOS Sierra versions, click Open Anyway or see Installing Mosa on page 22 to know how to add the Anywhere option. 5. Close the dialog box. Sensor has difficulty connecting to Mosa Mosa is very slow or unable to detect the sensor. The bluetooth does not work correctly. 1. Connect and disconnect the sensor to a charger to make the sensor reboot. The sensor is out of the bluetooth range. 1. Bring the sensor closer to the computer. 2. For door sensors that need to be in door pockets for calibration: remove the sensor from the door, establish the connection, then put the sensor back in the door. 3. To extend the Bluetooth range, you can use a Bluetooth key (ref. TRENDnet TBW-106UB) with a USB extender connected to the computer. Place the Bluetooth key as close as possible to the sensor. Data in Scala is wrong Data displayed in Scala is wrong. For sensors with echograms, the echogram is noisy. There are signal interferences. 1. First, check that the sensor frequencies and telegrams are the same in the sensor configuration (via Mosa) and the receiver configuration (via Scala). 2. Check the frequencies of your other sensors to make sure there is enough distance between them. 3. Check the noise on the spectrum (see Checking Noise Interference on page 63). If the frequency where the sensor is placed is too noisy, change for a less noisy frequency: a. Spread Sensor: see Configuring Spread Sensor Telegrams on page 25 b. Door Sounder: see Configuring the Uplink and Down Settings on page 32 Important: Do not forget to also change the frequency on Scala receiver page. | 68 Door Sensors | V1 | Servicing and Maintenance 4. You can increase the uplink power of the sensor to increase the power of the signal transmitted to the receiver: see Configuring the Uplink Power on page 35. 5. For sensors with echograms you can change the Echogram filter on Scala receiver page: a. From Scala, click Menu > Expert Mode and enter the password copernic. b. Click again Menu > Receivers. c. From the left side of the receiver page, click the name of the sensor. d. From the sensor configuration page, click Configure next to Filter. e. From NBTE Echograms Filter select Echosounder and Interference Reduction Medium or High. In Scala, Lost is displayed instead of spread distance From Sensors Data in the control panels, it is written Lost instead of distance data. Trawl doors may not be aligned or may lay on their side. 1. Check the pitch and roll. 2. If needed, pull the warps to align the doors or set them back upright. The sensors are placed backwards in the doors. 1. Remove the sensors from the pocket. 2. Check that the extremity of the sensor with a marker is on the top and that the side with a circle is oriented towards the outside. Master and Starboard sensors have been inverted on the doors. In that case, you will also have wrong pitch and roll values. Open the pocket and check the top of the housing of the sensor: the one with a green marker must be on the starboard side and the one with a red marker on the port side. If there is no marker on the top, remove the sensor and check on the side if there is a marker. The extremity with a circle must be oriented towards the outside. | 69 Door Sensors | V1 | Servicing and Maintenance If you used to have correct data and suddenly lost them, the up or down component in the transducer may be broken. 1. Remove sensors from the doors and check from the office if Lost is still displayed. 2. If yes, see with support service for repair. Distance between trawl doors distance is more than 250 m and the sensor telegram does not cover such a distance. Change the sensor telegrams to AL6 or A6: see Configuring Spread Sensor Telegrams on page 25. Distances are incorrect or irregular Distances displayed in Scala do not correspond to the reality or distance values are very irregular. The threshold of the sensor detection level is too low. 1. Connect the sensor to Mosa. 2. From Mosa, click Menu > Expert Mode and enter the password copernic. 3. Click the tab Spread and from Threshold Detection Level, add 10 to the current level. 4. Test the sensor, and if needed, add 10 again. There is a conflict between frequencies. Make sure there is a minimum distance of 100 Hz between all the telegram frequencies. The spread telegrams you entered in Mosa and those you entered in the receiver page on Scala are not the same. Compare the telegrams you configured on Mosa and those you entered in the receiver page. Change if necessary. If the distances are very small such as 1 meter or less, the Master and Starboard sensors have been inverted on the doors. In that case, you will also have wrong pitch and roll values. Open the pocket and check the top of the housing of the sensor: the one with a green marker must be on the starboard side and the one with a red marker on the port side. | 70 Door Sensors | V1 | Servicing and Maintenance If there is no marker on the top, remove the sensor and check on the side if there is a marker. The extremity with a circle must be oriented towards the outside. Echogram is fixed and blue The echogram displayed in Scala is completely blue. There is no yellow line moving on top of the echogram, which means that no sonar data is received. Sounder frequency may be outside the correct frequency range. 1. From Mosa, click Trawl Explorer > Ping Down Frequency and check that the frequency is between 120-210 kHz for a Door Sounder. 2. If not, change the frequency. You may have dragged and dropped wrong sonar data to the display. 1. Check that the name of the sensor on the top left corner of the echogram is Door Sounder or Bottom Explorer (Door Sounder with target strength calibration). 2. If not, from Door Sounder or Bottom Explorer in Sensors Data, click + hold Range of Sonar Data and drag it to the page display. The sounder in the transducer is damaged.
