1 Introduction
1.1 General overview
The AI50 is a collision warning device that has been designed for maximum safety. It is housed in a rugged waterproof enclosure to withstand the rigors of the marine environment and it has a bright, crystal clear, color display for easy viewing.
Figure 1.1 - AI50 Class B Transceiver
It displays the position of other AIS transmitting vessels within VHF range and allows other vessels and shore based stations to see you - even at night or in poor visibility.
With safety in mind it is very easy to initiate calls to target vessels via a networked DSC VHF Radio.
The AI50 can be flush mounted or bracket mounted and be located at any convenient position such as the helm pod or at the navigation table.
The AI50 uses a sophisticated automatic digital time sharing technology which enable the exchange of static information like; MMSI (Maritime Mobile Service Identifier) Number, Vessel’s Name, Call Sign and Type. Also dynamic data like; Position, Course, Distance and more, from ship to ship, and from ship to shore based traffic stations.
Page 10
10 Introduction
The advantages of the AI50 are:
Increased awareness of the current shipping situation within your VHF range through the exchange of data between vessels.
Improving traffic management in busy shipping lanes through exchanging information between vessels and shore based traffic stations.
Reporting information automatically in shipping areas where it is mandatory.
As with all electronic navigational equipment, it is only an aid to navigation and should not be used as a substitute for good seamanship.
Remember - Maritime law requires that you keep a good lookout at all times.
The position of a vessel on the screen is the position of the most recent transmission and may not be the current position.
1.2 About this manual
The manual combines operating and installation information for the AI50. Operation is sub-divided into main working categories for easy reference.
1.3 SimNet/NMEA2000
SimNet is Simrad’s proprietary high speed data bus network complete with NMEA2000. It provides intelligent sharing of data and control information between a wide range of marine electronics and instruments.
1.4 WR20 Remote (not supplied)
The WR20 Remote Commander is a handheld wireless command centre, which enables you to remotely control your AI50, as well as all of your other SimNet electronics, such as Plotters/Radar, Autopilots and Instruments. It will also control the VHF with the advanced features of voice

Introduction 11
calls, and when paired to a mobile phone it offers the same operating features as a Bluetooth Handset.
The WR20 Handset has been designed to survive the rigours of the marine environment. It has a tough, sealed body that is fully waterproof and houses an integral Li­Ion rechargeable battery that is automatically charged whenever it is placed in its cradle.

2.1 General
The AI50 can be fl ush mounted or bracket mounted, however, to determine the best possible location for good navigation, you need to consider these few options:
For ease of use - keep it within easy reach For good screen visibility - keep away from direct sunlight if possible Ensure good ventilation Decide how and where, you are going to run the cabling from the rear of the unit.
The AI50 is very simple to install, however, the performance of the equipment is directly affected by the quality of the installation. Please read these instructions carefully before attempting installation. If in any doubt, consult a qualifi ed marine electronics engineer.
2.2 Panel mounting
The transceiver requires a flat surface with an area of at least 172mm x 115mm (6.8in x 4.5in) for mounting.
Figure. 2.1 – Panel Cut-out drawing
Page 14
14 Installation
Allow sufficient space behind the unit for cable entry – at least 50mm (2.0in), in addition to the depth of the unit, is recommended.
The surface should be rigid and sturdy enough to be able to support the weight of the unit, taking into account the shock loads likely to be encountered when the vessel is under way in heavy seas.
Remove the backing paper and stick the cutting template onto your console or panel where the unit is to be mounted. Drill a 2.5mm hole in each corner, where shown, to fasten the unit. Drill 8 x 6mm holes where shown to assist in cutting the case peripheral hole. Carefully cut the hole where shown on the template. Remove the template. Assemble case gasket to the rear of the AI50 unit. Place the AI50 unit in the cut-out and fasten with 4 self tapping screws into 2.5mm holes. Carefully remove 4 corners, (3 left and 3 right supplied), from the moulding rosette. (Note: they are numbered 1 and 2 on rear) Place the 4 snap fi t, removable corner covers into place. (No.1 is placed in the bottom left and top right position, No. 2 is placed in the top left and bottom right position.
2.3 Bracket mounting
Using the supplied bracket as a template, hold it against the surface it is going to be mounted on. With a marker pen, make a mark through the centre of the holes and drill a 3.5mm pilot hole on each mark. Secure to the surface with the supplied self tapping screws.
2.4 GPS antenna
The antenna, ideally needs to be mounted as low as possible with a clear view of the sky to minimise

errors due to movement over and above the transitory movement of the vessel.
The GPS antenna is capable of being flush mounted on a suitable flat area of the cabin roof or deck area. In this configuration, fit the supplied rubber gasket under the antenna and use the four threaded studs, nuts and washers to fix the antenna down.
The cable can be routed in the molding to drop down directly underneath, or by breaking out the thin traps, the cable can be routed out of the side of the antenna.
Alternatively, the antenna may be fixed on a standard 1” threaded mounting pole (Not supplied). Attach the supplied mounting base to the antenna with the four screws, thread the cable down the center hole and through the pole. Thread the pole into the mounting base, before attaching the pole to the superstructure.
DO NOT connect your antenna using further extension cables, or remove the connector, as this may degrade the reception to a point where it may not function correctly.
To minimize interference, place the antenna in a position away from steel constructions, wires, metal masts, sources of electrical interference, such as radar etc. If installing the GPS antenna close to other antennas, mount it either above or below their radiation beams.
The antenna cable is terminated in a push fit connector (SMB). Push the antenna plug firmly into the socket on the back of the AI50.
The following drawing is a guide to the connections on the rear of the unit. Figure 2.2.

2.5 VHF antenna
North American Users - To meet FCC (Federal Communications Commission) rules on Radio Frequency Exposure, it is recommended that the VHF antenna is mounted at least 3m (10ft) away from any area accessible to any personnel on board. If this distance is achieved by vertical separation, the antenna must be at least 5m (16.5ft) above deck. This guideline applies only to antennas not exceeding 3dBi gain.
Failure to observe these recommendations may expose those within the MPE (Maximum Permitted Exposure) radius of 1m (3ft) to RF absorption levels that exceed the FCC safe limits.
The most important factor in the performance of any AIS transceiver will be the quality and positioning of the antenna.
As the range of VHF signals are governed by line of sight, the antenna should be placed as high as possible, while remaining clear of any metallic objects.
Long whip antennae are generally recommended for larger boats, although the most popular antennae for marine use is 1m (3ft 3in) long. On sailboats these are
))
Page 17
Installation 17
usually mounted on the masthead, where the length of the antenna keeps it clear from the navigation lights and wind vanes. This type of antenna can also be mounted on the cockpit roof or powerboat garages.
For maximum range, it is recommended that a VHF antenna specifically tuned for use with an AIS is used, and mounted away from the standard VHF antenna. Vertical separation is preferred, but where this is not practical, at least 5 metre horizontal spacing is recommended
The antenna coaxial cable and any connectors used must be rated at 50Ω. Under no circumstances should standard domestic TV cable and connectors be used. Incorrectly rated cabling and connectors could result in power not reaching the antenna, but also power could be refl ected back into the AI50 unit, reducing its performance.
The quality of any connections and integrity of the cable will directly affect the performance of the radio. Poor soldering or corrosion of the terminals can impair performance. We recommend that screw or crimp terminal type connectors are not used for any through deck fittings - a good quality waterproof solder terminal connector will be less susceptible to poor connection due to corrosion of the contacts.
To ensure the best performance of the radio, the antenna cable should be routed where it is least likely to interfere with, or receive interference from other electronic equipment, such as echo sounder transducer cables and high current carrying cables.
The antenna cable should terminate in a standard marine PL259 plug fitting. Connect the antenna plug to the socket on the back of the AI50 and screw the retaining collar down. Figure 2.3.

Figure 2.3 - VHF Antenna connection
To avoid possible water damage to the transceiver, it is recommended that all cables are looped to provide a drip path.
2.6 Power/data cable
Power cable
The electrical installation is quite straightforward - push the connector end of the supplied Power/Data cable fi rmly into the socket on the rear of the unit. The Power cable has two wires, one red and one black. Connect the red cable to +12V via a 2 Amp fuse, and the black cable to 0V.
Data cable
The data cable is used for connectivity to AIS enabled chart plotters with NMEA0183-HS interface. The Data cable is screened and has four wires. For connection data refer to the following table.

The spare socket can be used to daisy chain SimNet to another item of equipment. If the spare socket is not used insert the supplied blanking plug.
2.8 SD card (not supplied)
The SD card slot is situated on the reverse of the unit under a water resistant cover.
Figure. 2.5 - SD Card Access Cover
DO NOT insert or remove the SD card while the AI50 is turned on.
Locate and undo the two retaining screws, and carefully remove the cover to reveal the SD card slot.
With the SD card, contact side down, place under the shroud and slide fi rmly into place, making sure the card is sitting squarely and not at an angle.

Your vessel will be shown in the lower half of the screen and pointing towards the top. It will remain like this for the duration of this mode, and when your vessel turns, the map will rotate about it.
If in this mode you start tracking your own vessel, if “Show Range Rings” is activated, the range rings will disappear and the boat will move up the display under its own heading.
The display could also work for a COG-Up, but the relationship between the vessel and the map might not be representative of actual events taking place, due to the infl uences of the wind and tide. Therefore, if no compass is connected to the system, this mode will automatically appear as COG-Up.

8.1 General
This section details the types of visual alarms, alerts and warnings used by the AI50. All alarm windows will have a hazard symbol displayed in the title bar.
All alarms relating to another vessel will display the following information about that vessel when triggered:
MMSI Ships Name Latitude Longitude UTC Bearing COG SOG CPA TCPA
Each alarm state produced by the AI50 has an order of priority dependent on how serious the alarm condition is these are shown with their respective warning icon below:
Level 1 – is the highest priority alarm, which require immediate action. This alarm status if not acted upon with great urgency, could result in loss or serious damage to your vessel and /or loss of life.
Level 2 – high priority requires prompt attention. If this alarm status is not acted upon with some urgency, it could possibly develop into a “Level 1” Alarm resulting in loss or serious damage to your vessel and /or loss of life.
Level 3 – medium priority, and are reserved for warnings of a less urgent nature.
All audible and visual alarms will remain until confi rmed and cleared. If further alarms are activated before the current one is cleared, they will be stacked up and displayed in order of their priority, the highest priority being at the top.

8.2 Collision avoidance alarms
The Simrad AI50 boasts a sophisticated, very simple to use, collision avoidance alarm system. Which, when enabled, becomes an important aid in the prevention of collisions at sea and ensures even greater safety for your vessel and passengers.
These collision alarms are:
CPA/TCPA alarm Lost Vessel alarm Guard Zone alarm
CPA/TCPA alarm
This is a Level 1 alarm. If you have activated the CPA/TCPA Alarm from within the “Alarm Setup” Menu, the CPA/TCPA is then calculated from the received position, COG and SOG of the AIS transmissions, from all AIS equipped vessels within VHF range.
CPA – “Closest Point of Approach” is the calculated distance of how close a vessel will pass.
TCPA – “Time to Closest Point of Approach” is the calculated time to reach the CPA.
The CPA/TCPA alarm values are set by the user, as described in section 6.5. These are based on the last calculated COG and SOG, assuming the vessel continues on the same course, at the same speed.
It is the responsibility of the user to determine how close another vessel may pass without being dangerous, and how quickly the user can react to manoeuvre their own vessel in order to avoid a collision.
If both values calculated by the AI50 are less than, or equal to the values set by the user, then an alarm will activate, regardless of what screen the unit is in.
An audible alarm will sound and a window will open displaying the following information. Figure 8.1.

Because this information is live, it is continuously being recalculated and updated.
To confirm and clear this alarm, press W, this will close the window and return you to current display.
The icon of the vessel which caused the alarm to activate will turn red, indicating an alarm condition still exists.
Figure 8.2 – Collision Alarm view
It is the responsibility of the vessel’s captain to determine what action to take in this situation in order to avoid a collision.
Once action has been taken, and the calculated values increase beyond the limits as set in the “Collision Alarm” menu, the vessel’s icon will return to its normal state.

Lost vessel alarm (1)
This is a Level 1 alarm and will sound whether the Lost Vessel alarm, as described in Section 6.5, has been set by the user or not.
If a vessel activates a CPA/TCPA or Guard Zone alarm, and the AIS transmissions from that vessel are lost; regardless of what screen the AI50 is in, an audible alarm will sound and a “Lost Vessel Collision Alert” window will open, displaying the last received information.
To confirm and clear this alarm, press W, this will close the window and return you to current display.
The icon of the vessel which caused the alarm to activate will change to a “Lost Vessel” icon. Refer to section 7.2. It will retain its previous color and bold outlines, and flash at a rate of once every second, indicating that this condition still exists.
The icon will remain on the display in this state for 10 minutes before being erased. However, if reception from the lost vessel’s AIS is re-established, the icon will return to its previous state.
Guard zone alarm
This is a Level 2 alarm. The guard zone is determined by the radius dimension entered during setup. Refer to Section 6.5. A red circle will surround your vessel, but the size will depend on the range selected.
If “Track Own Vessel” mode has been activated; the red circle will track with your own vessel’s icon.
For every AIS equipped vessel entering your Guard Zone, an alarm will be generated, regardless of what screen the AI50 is in, and a “Guard Zone Collision Warning” window will be displayed.

Figure 8.3 – Guard Zone Warning
To confirm and clear this alarm press ENTER/MENU. The icon of the vessel which caused the alarm to activate will turn red, indicating an alarm condition still exists.
Once a vessel leaves the Guard Zone its icon will return to the normal state.
8.3 BIIT alarm
The BIIT (Built In Integrity Test) is a Level 2 alarm.
The AI50 is constantly monitoring and testing the integrity of the AIS transceiver. Should a fault be detected within the unit, the small circle situated in the bottom right hand corner of the display flashes red, and a text message informs the user about the transceiver status.
The “BIIT” message will remain there until the fault is cleared by the AI50 circuitry, or the unit has been repaired.
If the unit is powered down with a BIIT fault still active, the fault type will be saved to memory and displayed the next time the AI50 is turned on.
8.4 Lost vessel alarm (2)
This is a Level 3 alarm, and will be activated when the AIS reception from a vessel is lost.
An audible alarm will sound and a “Lost Vessel Alarm” window will open, displaying the last received information.
To confirm and clear this alarm, press W, this will close the window and return you to current display.
Page 74
74 Alarms
The icon of the vessel which caused the alarm to activate will change to a “Lost Vessel” icon. Refer to section 7.2. If the text display is active, the text line for that vessel’s data will be greyed out.
If reception from the lost vessel’s AIS is re-established, then the icon will return to its previous state.
8.5 Favorites alarm
This is a Level 3 alarm, and will only display if the option has been activated in the “Alarm Setup Menu”. If a vessel entered on your favorites list comes within your VHF range the following window will open and the alarm will sound.
Figure 8.4 - Favorite ship alert
To confirm and clear this alarm, press W, this will close the window and return you to current display.
8.6 Loss of compass heading data
This is a Level 3 alarm, and will only activate if the SimNet/ NMEA2000 data for the ships compass is lost.
An audible alarm will sound and a “Loss of Compass” alarm window will open showing details of the lost compass and any other compatible compass units on the network.
Highlight an alternative device and select it.
If the ENTER/MENU key has been pressed without selecting a new compass, the unit will continue to operate without compass information, and any displays consisting of the vessel’s own heading will be blank.
If “HDG Up” or “North Up” View Point is selected, it will be cancelled and the display View Point changes to “COG Up”.
