These are important messages for safety, installation and usage of the product. 1.1 Safety warnings This equipment must be installed in accordance with the instructions provided in this manual. This AIS transceiver is an aid to navigation and must not be relied upon to provide accurate navigation information. AIS is not a replacement for vigilant human lookouts and other navigation aids such as RADAR. The performance of the transceiver may be seriously impaired if not installed as instructed in the user manual, or due to other factors such as weather and or nearby transmitting devices. Compatibility with other systems may vary and is reliant on the third party systems recognising the standard outputs from the transceiver. The manufacturer reserves the right to update and change these specifications at any time and without notice. Do not install this equipment in a flammable atmosphere such as in an engine room or near to fuel tanks. 1.2 General notices 1.2.1 Position source All marine Automatic Identification System (AIS) transceivers utilise a satellite based location system such as the Global Positioning Satellite (GPS) network. The accuracy of a GNSS position fix is variable and is affected by factors such as the antenna positioning, how many satellites are used to determine a position and how long satellite information has been received for.

Page 4 Notices 1.2.2 Compass safe distance The compass safe distance of this unit is 0.2m or greater for 0.3 deviation. 1.2.3 RF emissions notice Caution: The AIS transceiver generates and radiates radio frequency electromagnetic energy. This equipment must be installed and operated according to the instructions contained in this manual. Failure to do so can result in personal injury and / or AIS transceiver malfunction. Caution: Never operate the AIS transceiver unless it is connected to a VHF antenna. To maximise performance and minimise human exposure to radio frequency electromagnetic energy you must make sure that the antenna is mounted at least 1.5 metres away from the AIS transceiver and is connected to the AIS transceiver before power is applied. The system has a Maximum Permissible Exposure (MPE) radius of 1.5m. This has been determined assuming the maximum power of the AIS transceiver and using antennas with a maximum gain of 3dBi.The antenna should be mounted 3.5m above the deck in order to meet RF exposure requirements. Higher gain antennas will require a greater MPE radius. Do not operate the unit when anyone is within the MPE radius of the antenna (unless they are shielded from the antenna field by a grounded metallic barrier). The antenna should not be co-located or operated in conjunction with any other transmitting antenna.

Page 7 About your AIS class B transceiver 2 About your AIS class B transceiver 2.1 About AIS The marine Automatic Identification System (AIS) is a location and vessel information reporting system. It allows vessels equipped with AIS to automatically and dynamically share and regularly update their position, speed, course and other information such as vessel identity with similarly equipped vessels. Position is derived from the Global Navigation Satellite System (GNSS) and communication between vessels is by Very High Frequency (VHF) digital transmissions. There are a number of types of AIS device as follows:

Class A transceivers. These are similar to class B transceivers, but are designed to be fitted to large vessels such as cargo ships and large passenger vessels. Class A transceivers transmit at a higher VHF signal power than class B transceivers and therefore can be received by more distant vessels. They also transmit Class A transceivers are mandatory on all vessels over 300 gross tonnes on international voyages and certain types of passenger vessels under SOLAS regulations. Class B transceivers. Similar to class A transceivers in many ways, but are normally lower cost due to the less stringent performance requirements. Class B transceivers transmit at a lower power and at a lower reporting rate than class A transceivers. AIS base stations. AIS base stations are used by Vessel Traffic transmissions of AIS to monitor and control the Systems transceivers. Aids to Navigation (AtoN) transceivers. AtoNs are transceivers mounted on buoys or other hazards to shipping which transmit details of their location to the surrounding vessels. AIS receivers. AIS receivers will generally receive transmissions from class A transceivers, class B transceivers, AtoNs and AIS base stations but do not transmit any information about the vessel on which they are installed. Page 8 About your AIS class B transceiver This product is an AIS Class B transceiver. 2.2 Static and dynamic vessel data There are two categories of information transmitted by an AIS transceiver:

static and dynamic data. The vessel's dynamic data, which includes location, speed over ground

(SOG) and course over ground (COG), is calculated automatically using the internal GNSS receiver. Static data is information about the vessel which must be programmed into the AIS transceiver. This includes:

Maritime Mobile Service Identity (MMSI) Vessel name Vessel call sign (if available) Vessel type Vessel dimensions In most countries the operation of an AIS transceiver is included under the vessel's marine VHF license provisions. The vessel on to which the AIS unit is to be installed must therefore possess a current VHF radiotelephone license which lists the AIS system, vessel Call Sign and MMSI number.

An MMSI number is required in order for the AIS transceiver to operate. Please contact the relevant authority in your country for more information. 2.3 Important information for US customers There are specific laws in the USA regarding the configuration of AIS class B transceivers. If you are a US resident and intend to use your AIS class B transceiver in US waters, you should make sure that your retailer has configured your product prior to supplying it to you. If your AIS transceiver has not been pre-

configured please contact your dealer or support@em-trak.com for details of how to have it configured. Page 9 About your AIS class B transceiver

In the United States of America, the MMSI and static data must only be entered by a competent installer. The end user of the equipment is not authorised to enter their own vessel data. 2.4 Special features Some variants of this AIS Transceiver are WiFi and Bluetooth enabled, allowing for AIS data to be streamed from the transceiver to a 3rd party device or to the em-trak app CONECT-AIS. WiFi and Bluetooth enabled transceivers also provide an in-built vessel data logger which will continuously record its own GNSS position and can be downloaded using proAIS2 or CONNECT-AIS.

3.1.1 Screwdriver A small flat-headed screwdriver will be required to tighten the screw in the mounting bracket. Page 17 Installation 3.1.2 VHF antenna Connection to a suitable VHF antenna will be required for the AIS transceiver to receive and transmit. The standard transceiver variants will require an AIS antenna (tuned to 162MHz) for optimum performance. Transceiver/splitter variants will require a broadband antenna (tuned to 159MHz) so it will be compatible with both VHF radio (156MHz) and AIS

(162MHz). Please take note of the warnings in section 1 regarding the use of antennas. 3.1.3 Optional switch A switch can be connected to the transceiver to enable and disable

'silent mode' (see section 3.2). A latching toggle switch is recommended for this feature. 3.1.4 VHF antenna cable Please check that the VHF antenna you intend to use has sufficient cable to reach between the VHF antenna and the AIS transceiver unit. If it is not sufficient you will need an extension cable. RG-58 or RG-8X can be used for short distances, however for longer runs we would recommend a low loss cable like RG-213. For reference the VHF antenna connector type on the AIS transceiver unit is SO 239, and it is intended to mate with a PL 259 connector. 3.1.5 Power cable The AIS transceiver unit is supplied with a two metre long power and data cable. If you require a longer cable to reach your power supply, please ensure the it is capable of carrying currents up to 2A peak / 200mA nominal for the B92x variants, and 2.5A peak / 220mA nominal for the B95x variants. Means of connecting the cables together will also be required, and we recommend ScotchlokTM connectors for this purpose. 3.1.6 Chart plotter Your AIS transceiver can be interfaced with a chartplotter to display other vessels equipped with AIS. Please refer to the user manual supplied with your chart plotter for details of how to connect and configure your chart plotter Page 18 Installation for use with AIS devices. Depending on the interfaces supported by your chartplotter, you can connect in the following ways:

NMEA 0183 - we recommend that 38400 baud is used for outputting AIS data. This is also known as NMEA HS by some manufacturers. NMEA 2000 - you can connect to an existing NMEA 2000 network using a drop cable. This will allow you to output AIS data to any compatible devices that are connected on the network. WiFi - you can send AIS data over WiFi to any compatible chartplotter. This only applies to WiFi and Bluetooth enabled variants. 3.1.7 USB cable A micro USB cable will be required to connect the transceiver to a PC or laptop. This will be necessary if your transceiver is not already programmed. Configuration over USB requires our software tool, proAIS2. The USB interface can also be used to output AIS data to suitable navigation software installed on a PC or laptop. This is not required for WiFi and Bluetooth enabled variants, which can also be configured using the CONNECT-AIS app. 3.1.8 Mobile devices WiFi and Bluetooth enabled transceivers can be connected wirelessly to any compatible mobile device. Data can be streamed to three devices simultaneously when in Access Point mode. You can use a smart phone to configure the transceiver using the CONNECT-

AIS app, available for download from the App Store and Google Play. Page 19 Installation 3.2 Installation procedures Before beginning installation of your AIS transceiver, please ensure you have any necessary additional items as detailed in section 3.1. It is strongly recommended that you read all of the instructions in this manual prior to installation. If after reading this manual you are unsure about any element of the installation process please contact your dealer or support@em-trak.com for advice. The following sections explain the installation process step by step for each of the main elements of the system. Step 1 - Installing the AIS transceiver Please note the following guidelines when selecting a location for your AIS transceiver:

The AIS transceiver must be fitted in a location where it is at least 0.2m from a compass or any magnetic device. There should be adequate space around the AIS transceiver for routing of cables. See Figure 6 for details of the AIS transceiver dimensions. The ambient temperature around the AIS transceiver should be maintained between -25C and +55C. The AIS transceiver should not be located in a flammable or hazardous atmosphere such as in an engine room or near to fuel tanks. The transceiver should be mounted horizontally, with the LEDs facing up, for optimum performance of the internal GNSS antenna. A mounting bracket and four self tapping screws are supplied for attachment of the AIS transceiver to a suitable surface. Please refer to Figure 7 for guidance. The AIS transceiver should be mounted in a location where the indicators are readily visible as they provide important information on the status of the AIS transceiver. Page 20 Installation m m 5 1 1 The transceiver should be mounted at least 1m away from sources of interference like VHF radios, transmitting antennas, radar, etc. 150 mm 43 mm m m 5 1 1 150 mm Figure 6 AIS transceiver dimensions 1. Mount the bracket to the suitable surface using the four self-tapping screws provided. A mounting template is provided to assist with drilling the correct hole positions. 2. Connect all the RF and power and data cables. 3. Clip the AIS transceiver onto the security bracket by lining up the two tabs with the corresponding slots and sliding the unit down. The tab on the unit should then engage with the slot in the mounting bracket. 4. Screw the captive security screw in the bracket into the AIS transceiver to lock it in place.

There is also the facility to connect an optional external GNSS antenna, which is available for purchase from em-

trak. Please contact support@em-trak for more information. Please note the following guidelines when installing an external GNSS antenna. You will require a one inch 14 TPI threaded pole to mount the GNSS antenna. entire sky. You should ensure the GNSS antenna has a good clear view of the The GNSS antenna should not be mounted up a mast where the motion of the vessel will cause the antenna to swing and potentially reduce the position accuracy. Do not mount your antenna in the direct path of a radar or any other transmitting equipment. Feed the ten metre long cable attached to the GNSS antenna cable through the pole and screw the antenna onto the pole mount as shown in Figure 8. Route the cable to your AIS transceiver unit. Connect the cable from the GNSS antenna to the GNSS connector on the AIS transceiver as shown in Figure 9. Figure 8 External GNSS antenna mounting Page 23 Installation B921, B922, B951 and B952 B923, B924, B953 and B954 GNSS antenna GNSS antenna Figure 9 Position of the GNSS antenna connector Step 3 - Connecting the VHF antenna Route the cable from the VHF antenna to the AIS transceiver and connect to the VHF connector on the AIS transceiver as shown in Figure 10. The standard transceiver variants (B921, B922, B951 and B952) will require an AIS antenna (tuned to 162MHz) for optimum performance. Transceiver/splitter variants (B923, B924, B953 and B954) will require a broadband antenna (tuned to 159MHz) so it will be compatible with both VHF radio (156MHz) and AIS (162MHz). The connector type on the AIS transceiver is SO239. The VHF antenna requires a PL259 connector to mate with this. If your VHF antenna does not use this type of connector please contact your dealer or support@em-

This item is not supplied so you will need to purchase one from your local dealer. Starter kits are available to purchase if you do not already have an NMEA 2000 network. The list of supported NMEA 2000 data (PGNs) is detailed in Section 7.1 Step 7 - Connecting to NMEA0183 compatible equipment The NMEA0183 data ports allows connection to your chart plotter or other NMEA0183 compatible equipment. Each port consists of four wires colour coded as shown in Table 5and in Figure 12. Other manufacturers may use different signal names, however the following general guidelines will apply:

positive signals should be connected together negative signals should be connected together transmit signals should be connected to receive signals and vice versa. Please refer to your equipment manual for more information. The AIS transceiver has a configurable high speed port which operates at 38,400baud at default. The port is intended primarily to connect to a chart plotter, but can used to connect to other NMEA0183 devices. Please ensure your equipment is configured to use the correct baud rate. Both ports support bi-directional multiplexing, which means that any data received on port 1 will be automatically output on port 2, and vice versa. This can be useful when connecting to a chartplotter that only has a single NMEA0183 port, so a sensor can be connected to port 2 on the transceiver, where the received sensor data will combine with AIS data and get output on port 1.

Download and extract the zip file to your local PC or laptop. For Windows installations you will need to open the 'en-us' folder and run the setup.exe or proAIS2.msi files before following the on-screen prompts. For MacOS X installations you will need to open the OSX folder and run the proAIS2.dmg file. 2. If a security warning appears, click 'Install' to continue with the installation. 3. For Windows installations, the USB drivers can be optionally installed at the same time. This will be required to allow your PC or laptop to recog-

nise the transceiver COM port. Once installation is complete, a start menu folder and shortcut can be created for future use. 4.5 Configuration using proAIS2 For configuration purposes only, it is possible to power the AIS transceiver via its USB connection. This is useful if you wish to configure your AIS transceiver away from the vessel power supply. The AIS transceiver will not transmit or receive any data whilst powered by USB only. Page 33 You will require the following information in order to configure your AIS transceiver:

Configuring your AIS transceiver MMSI Vessel name Vessel type Vessel dimensions and position of your GNSS antenna installation. For further assistance in configuring your AIS transceiver please refer to the Help menu within proAIS2.

Please ensure that you enter all vessel data accurately. Failure to do so could result in other vessels failing to identify your vessel correctly. The vessel MMSI can only be programmed once using proAIS2, please take care to program your MMSI correctly. If you need to change the MMSI for any reason, please contact your dealer or support@em-trak.com who for support. 4.6 WiFi and Bluetooth Configuration using ProAIS2 This section applies to AIS transceivers with the WiFi and Bluetooth feature only. (B922, B924, B952 and B954) Using the proAIS2 software, the WiFi and Bluetooth feature can be configured for a user's specific needs. Connect the AIS transceiver to the computer with a USB cable and apply external power (12-24V). Run the proAIS2 software and press the Connect button. 4.6.1 WiFi configuration By selecting the WiFi tab on proAIS2, you are able to configure the various WiFi parameters. The WiFi interface supports both Client and Access Point modes. Client mode will allow your transceiver to join an existing network. Access Point mode enables your transceiver to create it's own network. The following parameters can be configured:

Page 34 Configuring your AIS transceiver WiFi network name (the SSID will be blank, any name can be entered by user), IP address of the network (e.g. 192.168.0.1) Password - Any 8 characters or more. WiFi Channel - Preferably 1, 6, or 11). Port address (e.g. 2002) Once the Write Configuration button is pressed on proAIS2, the WiFi feature will be enabled with these settings. Tablet Laptop Class B AIS transceiver Smartphone Figure 15 Typical mobile devices for WiFi and Bluetooth connection. 4.6.2 Location Requirements A number of factors can affect the WiFi and Bluetooth propagation. For optimum performance we recommend that the transceiver is installed near the center of the boat to provide a consistent signal across all areas. Consider testing the reception to ensure you're happy before you mount the bracket and transceiver. 4.6.3 Distance and signal strength The distance between WiFi and Bluetooth products should always be kept to a minimum. Products installed close to their maximum WiFi range may Page 35 Configuring your AIS transceiver experience slow connection speeds, signal dropouts or not being able to connect at all. 4.6.4 Line of sight and obstacles For best results, WiFi and Bluetooth products should have a clear, direct line of sight to the transceiver. Any physical obstruction can degrade or even block the signal. The construction of your vessel can also have an impact on performance. For example, metal structural bulk heads and roofing, power cables and reflective surfaces can reduce and in certain situations, block the signal. The AIS transceiver should be installed at least 1m(3ft) away from:

Other WiFi enabled products Transmitting products that send wireless signals in the same Other electrical, electronic or electromagnetic equipment that may frequency range generate interference. Page 36 Configuring your AIS transceiver 4.7 Configuration using the CONNECT-AIS Once CONNECT-AIS is installed on your smart-phone you will need to carry out the following to configure your transceiver:

1. Ensure the AIS transceiver is installed correctly and is powered up by 12 -

24V. 2. Start CONNECT-AIS. You will see a welcome screen. 3. Select Lets Begin and the Setting up your AIS screen will appear 4. If you have all your correct vessel information available select Im ready You will then see the Connect to your devices screen which will show all the available WiFi devices within range. 5. Select the number of the AIS transceiver being configured (this is printed on a label on the side of the unit). Create a connection. You will see a message confirming you are connected. 6. CONNECT-AIS will now guide you through configuring your vessel infor-

mation. Complete the information boxes with the relevant vessel informa-

tion and select Next when done. 7. Insert the vessel dimensions and select Next when done 8. Select the position of your GNSS antenna aboard the vessel. (If you are using the internal GNSS antenna within the AIS transceiver then select the position of the AIS transceiver instead). Select Complete when done. 9. CONNECT-AIS will now display the active chart display which will show other vessels with AIS in the vicinity. The next time you open CONNECT-AIS it will connect automatically and go straight to the home screen. Page 37 Operation 5 Operation 5.1 Using the AIS transceiver Once the unit has been configured it is ready for use. Providing other vessels installed with AIS transceivers are within radio range of your vessel you should see their details appear on your chart plotter, PC / laptop or mobile device. Please note that your full vessel details may not be visible to other vessels immediately as static data messages (containing vessel name, call sign, etc) are required to be transmitted every 6 minutes. 5.2 Switch functions Using the instructions in Section 3.2 an external switch provides the ability to set the AIS transceiver into 'silent mode'. In silent mode the transmission of your own vessel position ceases, whilst the reception of other vessel's AIS position continues. When silent mode is active the blue indicator will be illuminated.This is also reflected in the Diagnostics tab of proAIS2.

When silent mode is active other vessels will not be able to receive your vessel information on their AIS devices. Your navigational safety may be compromised as a result. Page 38 Operation 5.3 Indicator functions The AIS transceiver includes four coloured indicators as shown in Figure 16. The state of the indicators provide information regarding the status of the AIS transceiver. Indicator lights Figure 16 Indicator location on the AIS transceiver unit The meaning of each indicator is shown in the table below Figure 16 shows the indicator positions on the AIS transceiver. Green indicator The AIS transceiver is configured and powered up. Red indicator The AIS transceiver has detected a system error. The likely causes of this are detailed in the troubleshooting guide in Section 8. Alarms displayed in the Diagnostic tab of proAIS2 will also assist with troubleshooting. Blue indicator When silent mode is activated using the optional silent mode switch the transmitter is disabled. Page 39 Operation Amber indicator The AIS transceiver is not transmitting. This can be for a number of reasons:

The AIS radio channels are exceptionally busy so there are currently no available slots for transmission. The unit has been in silent mode and after deactivating silent mode this amber indicator will illuminate until the first AIS message has been sent The AIS transceiver has been commanded by the local authority (via an AIS base station) to cease transmissions. Page 40 Voyage Data Recorder 6 Voyage Data Recorder This feature is available on AIS transceivers with the WiFi and Bluetooth Features only (B922, B924, B952 and B954). The transceiver will log your own position at regular intervals if your position has changed by more than 10m. Data is stored for 30 days. The VDR log can be retrieved from the VDR tab within proAIS2. The start and end dates of the log file are interrogated so you can select a date range to download. Once the date range is selected you need to select the download location. Data is saved as RMC sentences, which can be decoded and displayed by a range of on-line tools and navigation applications.
