Installation

Installing your B900 series

Please complete the MMSI change form on our website here – https://em-trak.com/accessories/mmsi-number-change-service

Once payment is confirmed, we will send you the configuration file along with the instructions to change your MMSI.

VHF Antenna: Connection to a suitable VHF antenna will be required for the AIS transceiver to receive and transmit. The B900 unit will require an VHF antenna (tuned to a centre frequency of 162MHz – for best possible AIS reception) for optimum performance. For installations using a splitter, the entire Marine band VHF is required so we recommend a VHF antenna suitable for 156MHz to 162MHz (tuned to a centre frequency of 159 MHz) in these cases.

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 enough 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 is intended to mate with a PL 259 connector.

Power Cable: The AIS transceiver unit is supplied with a two metre long power and data cable. If you require longer cables to reach your power supply, please ensure the cables are capable of carrying currents of up to 2A peak and 200mA on average. Means of connecting the cables together will also be required.

Chart plotter:
To display received AIS messages from other vessels on your chart plotter, you will need to connect your AIS transceiver to your chart plotter. Please refer to the user manual supplied with your chart plotter for details of how to connect and configure your chart plotter for use with AIS devices. For general guidance your chart plotter should be configured to accept NMEA data at 38400 baud (sometimes referred to as ‘NMEA HS’ in the plotter configuration menu). You may also need to enable the display of AIS targets in the chart options.
Alternatively if you use an NMEA2000 network on your vessel it is possible to connect the AIS transceiver to the NMEA2000 network via a suitable cable. Please refer to your dealer for details of NMEA2000 cables.

Configuration of the AIS is carried out using our configuration software proAIS2. A guide on how to use proAIS2 in the FAQ section under How do I use proAIS2?

A copy of proAIS2 is available in the Configuration Software section

WiFi variants like the B922 and B924 can be configured using the Connect-AIS app available on IOS and Android devices. A guide on how to use Connect-AIS in the FAQ section under How do I use Connect-AIS?

Summary

Before beginning installation of your transceiver, ensure you have any necessary additional items as detailed below. 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, contact your dealer or support@em-trak.com for advice.

Installation-CH-with-AS.png

Figure 6 Typical Installation configuration

In addition to the items supplied, the following may also be required for your installation:

  • VHF antenna and cable – this is required for your transceiver to receive and transmit. A variant with an integrated splitter (B923/B924/B953/B954) can use an existing VHF antenna providing it is tuned to operate across the frequency range 156MHz to 162MHz. VHF antenna installation is covered in more detail in 1. If you need to extend the antenna cable when connecting to your existing VHF antenna, RG-58 or RG-8X can be used for short distances. For longer runs we would recommend a low loss cable like RG-213.

  • External GPS antenna – this may be required if your installation location is deep inside your boat where the Integrated GPS receiver and antenna will not be able to receive satellite signals. GPS antenna installation is covered in more detail in GPS antenna.

  • Power cable – this may be required to extend the length of the 2m power and data cable that is supplied with your transceiver. If you require longer cables to reach your power supply, ensure they are capable of carrying currents of up to 2.5A peak and 220mA on average. Connecting the power supply is covered in more detail in Connecting power and data cable.

  • Toggle switch – this can be used to turn on/off silent mode. We would recommend a latching toggle switch for this application. Installation of the toggle switch is covered in more detail in Silent mode. Silent mode can also be controlled using the configuration tools.

Configuring your AIS transceiver

Depending on the variant of transceiver there are three ways in which your AIS transceiver can be configured.

Method 1: Configuration in advance by your dealer or installer.

If your AIS transceiver has been configured for you by your dealer or installer you can proceed to Connectivity. This is required for customers who have a US-registered vessel.

Method 2: Configuration using your PC

Figure 14 Configuration using your P.C

Method 3: Configuration using your smartphone

Figure 15 Configuration using your smartphone

VHF antenna

Connection to a suitable VHF antenna will be required for the transceiver to receive and transmit.

Transceiver variants (B921/B922/B951/B952) do not have an integrated splitter and will require a dedicated VHF antenna tuned to the AIS channels at 162MHz.

Integrated splitter variants (B923/B924/B953/B954) will require a VHF antenna tuned to operate across the frequency range 156MHz to 162MHz. That allows it to be compatible with both VHF radio (156MHz) and AIS (162MHz).

Connection-VHF-antenna-CH.png

Figure 7 VHF antenna connector

The VHF antenna connector type is SO-239. It requires a PL-259 mating connector for the antenna.

For optimum performance the VHF antenna should be mounted as high as possible, and as far away as possible from metal structures, obstructions or sources of interference. If another transmitting antenna is installed on the same vessel we would recommend a separation distance of at least 3m where possible.

GPS antenna

All B900 variants have an integrated high-performance GPS receiver & antenna, and are compatible with the GPS, GLONASS, Galileo, and BeiDou satellite navigation systems. A multi GPS mode can be enabled using proAIS2, allowing you to select combinations of the above systems. This will provide a more stable position fix, and also offers redundancy if one of the satellite systems goes offline. If you install it near a window, under a fiberglass deck or inside a centre console, you will not require an external GPS antenna. If your installation location is deep inside your boat where the GPS antenna will not be able to receive satellite signals you will need an external GPS antenna. We recommend the em-trak GPS100, which is available for purchase from www.em-trak.com.

GPS-Antenna.png

Figure 8 GPS antenna connector

Note the following guidelines when installing an external GPS antenna.

  • You will require a 1″ (inch) 14 Threads per inch (TPI) threaded mount if you choose to pole mount the GPS antenna.

  • The GPS antenna is also supplied with a gasket/thumb nuts/ studs so it can be deck mounted. The gasket can be used as a mounting template if required.

  • Mounting the external GPS antenna at a low point on the boat will minimise the effect of pitch and roll on your transmitted position.

  • Do not mount your antenna in the direct path of a radar or any other transmitting equipment.

Connecting power and data cable

A power and data cable is supplied with the product to provide connections for power, two NMEA 0183 data ports and the optional silent mode switch. The cable has a moulded connector at one end which should be connected to the 12 pin connector on the unit. The other end of the cable has 12 colour coded bare wires ready for connection.

Safety-Warnings.png WARNING
Check your wiring very carefully before applying power to the product. Failure to wire the product correctly could result in permanent damage.

The AIS transceiver is designed to operate at voltages from 9.6-31.2V, however for optimum performance we would recommend maintaining the voltage range at 12-24V.

It is recommended that crimped and soldered lugs are used to connect the AIS transceiver to the power source using a suitable circuit breaker and/or 3A fuse block. The red and black wires as shown in Figure 10 need to be connected as follows:

Connecting-to-a-power-supply-CH.png

Figure 10 Connecting the power supply

Location and fixing of the transceiver

The ambient temperature around the transceiver should be maintained between -25°C and +55°C.

The transceiver should not be located in a flammable or hazardous atmosphere, such as in an engine room or near to fuel tanks.

The transceiver must be fitted in a location where it is at least 0.2m from a compass or any magnetic device.

The transceiver should be mounted in a location where the LED indicators are readily visible as they provide important information on the status of the transceiver.

Wi-Fi & Bluetooth enabled variants (B922/B924/B952/B954) will benefit from being installed near the center of the boat to provide a consistent signal across all areas. 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. Consider testing the reception to ensure you’re happy before you mount the bracket and transceiver.

For optimum performance the transceiver should be mounted at least 0.5m away from other high power transmitting equipment like VHF radios.

There should be adequate space around the transceiver for routing of cables. See Figure 11 for details of the transceiver dimensions.

Dimensions.png

Figure 11 Transceiver dimensions

Bracket-Dimensions.png

Figure 12 FLEXI-FIT bracket

The B900 Series uses a simple bracket system to make installation as easy as possible. Use the bracket as a template to locate the desired position of the transceiver and simply screw or stick (adhesive pads are also supplied) the bracket to your vessel and then click the transceiver into the bracket. The secure clip will hold the transceiver securely in even the most severe weather and wave shocks.

To unclip the transceiver no tools are required. Simply push the release clip on the bracket with a finger or thumb and carefully rotate the transceiver and lift off the bracket.

Introduction to proAIS2

proAIS2 is available for download from www.em-trak.com/ installation and allows you to configure your transceiver using a PC or laptop over USB.

This configuration tool can be used to configure your vessel data, check the GPS antenna performance, view details on surrounding vessels, and monitor and diagnose the performance of the transceiver.

Installing proAIS2

  1. Download and extract the zip file to your local PC or laptop. For Windows installations you will need to open the appropriate folder and run the setup.exe or proAIS2.msi files before following the on-screen prompts. For macOS installations you will need to open the appropriate 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 is recommended for most installations and will be required to allow your PC or laptop to recognise the transceiver COM port. Once installation is complete, a start menu folder and shortcut can be created for future use.

Vessel data configuration using proAIS2

For configuration purposes only, it is possible to power the AIS transceiver using USB only. 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.

You will require the following information in order to configure your AIS transceiver:

  • MMSI

  • Vessel name

  • Vessel type

  • Vessel dimensions and position of your GPS antenna installation

Safety-Warnings-yellow.png

 CAUTION
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 configured once using proAIS2. If you need to change the MMSI for any reason, contact your dealer or support@em-trak.com and provide the product serial number, current MMSI number and new MMSI number.

Wi-Fi configuration using proAIS2

This section applies to Wi-Fi & Bluetooth enabled variants (B922, B924, B952 and B954).

The Wi-Fi interface can be configured using the Wi-Fi tab.

Access point mode

This mode enables your transceiver to create its own network. The following parameters can be configured:

  • AP SSID (the default is <B900 model>_<alphanumeric number>)

  • IP address (the default is 192.168.2.1)

  • Password (The unique password is stated on a sticker adhered to the product)

  • Port (the default is 5000)

Access point mode supports data streaming to two clients simultaneously.

Bluetooth

The Bluetooth interface uses the same ID as the default Wi-Fi AP SSID.

For security purposes there is a 10 minute window from initialisation where the Bluetooth interface is available for pairing. After this window expires it will disappear from device lists. Active connections will not be affected by this. If you wish to make the Bluetooth interface visible again for a further 10 minutes you will need to completely remove and reapply the power (including USB). The Bluetooth interface supports data streaming to seven devices simultaneously.

There is also an option to completely turn off Bluetooth if required.

The Bluetooth interface is not supported by Apple devices.

Introduction to CONNECT-AIS

Wi-Fi & Bluetooth variants of the transceiver (B922/B924/B952/ B954) can be configured using the CONNECT-AIS app.

CONNECT-AIS is available for download from Google Play and the App Store.

This configuration tool can be used to configure your vessel data, check the GPS antenna performance, view details on surrounding vessels, and monitor and diagnose the performance of the transceiver.

Further information on how to use CONNECT-AIS can be found in the FAQ section for this product – https://em-trak.com/installation/.

Troubleshooting

Troubleshooting your B900 series

Troubleshooting

Issue Possible cause and remedy
No LED indicators are illuminated
  • Check that the power supply is connected correctly.
  • Check that the power supply is a 12V or 24V supply.
The red error LED indicator is flashing

There may be a problem with the VHF antenna system. This can be confirmed using the configuration tools. If the ‘High VSWR’ alarm is active, check for the following:

  • Faulty VHF antenna/cable/connectors.
  • Poor connection at the VHF antenna/cable/connectors.
  • Suitability of the VHF antenna. For B921/B922/B951/B952 an antenna tuned for AIS at 162MHz is recommended. For variants with a splitter (B923/B924/B953/B954) an antenna tuned to operate across the frequency range 156MHz to 162MHz is required.
  • VHF antenna location (ensure that is isn’t mounted near other transmitting antennas or sources of interference, metal structures, or other obstructions).
  • Check that the unit is configured with a valid MMSI number. This can be confirmed using the Configuration tools.
  • Check that the GPS antenna has a stable position fix. This can be confirmed using the configuration tools.
  • Check that the power supply is within 9.6 – 31.2V. This can be confirmed using the configuration tools.
The amber LED indicator is flashing continuously
  • The amber LED indicator flashes while the transceiver searches for a position fix. If it takes longer than a minute you can check the performance of the GPS antenna by using the configuration tools.
No data is being received by the chart plotter
  • Check that the signal wires are connected correctly.
  • Check that the baud rate matches both the transceiver and the chart plotter.
  • Confirm that other vessels are within radio range and that they are displayed on the Other Vessels tab of proAIS2 or CONNECTAIS.
My vessel name isn’t being received by other vessels
  • Static data (containing vessel name, call sign, etc) is transmitted every 6 minutes so it may take a few transmissions before all the vessel data is displayed.
  • Position reports contain critical data like position, MMSI number, vessel speed, etc and these are transmitted more regularly.
I can’t establish a connection using Wi-Fi or Bluetooth
  • Check that the transceiver is powered by 12 – 24V.
  • Check the configuration parameters using proAIS2.
  • Check that there are no obstructions between the transceiver and mobile device.
  • Check that there are no sources of interference nearby.
  • Check that the 10 minute Bluetooth pairing window hasn’t expired. If it has, you will need to completely remove and reapply the power (including USB).
  • Check that you’re not attempting to use Bluetooth with an Apple device.

If the guidance given above does not rectify the problem you are experiencing, contact your dealer or support@em-trak.com for further assistance.

Low Forward Power alarms are usually caused by:
  • Voltage drop
  • Power supply ripple
  • Poor vessel wiring
  • Transient voltage dips during transmission
In most cases, the issue is caused by insufficient power being available due to wiring between the battery and the transceiver. However, in a small number of cases, the alarm can also be caused by a hardware issue within the transceiver.
Step 1 — Test with a Stable Power Supply
If possible:
  • Disconnect the unit from the vessel supply
  • Test using a stable bench power supply or separate battery
If the alarm disappears, the issue is likely related to vessel wiring or supply quality.
Step 2 — Check Cable Size and Length
Undersized or excessively long cables can cause voltage drop during transmission.
AWG (American Wire Gauge) is used to describe wire thickness:
  • Lower AWG number = thicker cable
  • Higher AWG number = thinner cable
Thicker cable reduces voltage drop and is recommended for longer cable runs.
Please see the table below for recommended cable sizes and maximum cable lengths.

These recommendations are based on the worst-case current requirements across the supported transceiver range.

If you’re having difficulty displaying AIS on your chartplotter, please follow the instructions below.

  1. Some old Chart plotters do not support AIS so you’ll need to confirm compatibility by checking the manual for reference to AIS and/or VDM.
  2. Check the receiving port can be configured to 38400 baud on the chart plotter.
  3. Make sure it’s connected correctly by simply connecting the NMEA 0183 transmit wires on the B900 Series (Brown is TX+, Blue is TX-) to the corresponding NMEA 0183 receive wires on your compatible chartplotter. You’ll need to connect the positive wires together and the negative wires together. For example:
    • TX+ to RX+
    • TX- to RX –

The user manual details the function of each wire, but for your reference please see below a table explaining the connections on the B900 Series:

If you need any further assistance, please contact us at support@em-trak.com and we’ll be glad to help.

The RX 1 / RX 2 DSC start / Stop message is a completely normal message and is not an indication of a fault or problem.

Essentially, it’s just a text message indicating when one of the AIS receivers has started/stopped a DSC channel management listening period. Class B AIS transceivers are required to listen to channel 70 (the DSC channel) periodically at specific times defined in the standards, for DSC channel management commands.

The following LED status modes will be available to assist in the quick diagnosis of issues:

1 – Solid red and amber LEDs: No MMSI / external power outside of required range (12-24V)

2 – Flashing amber LED: the unit is waiting for a GPS fix.

3 – Flashing red LED: VSWR exceeding limit. (Good VSWR is around 1.2:1)

4 – Solid red LED: System error (check Diagnostics tab of proAIS2 for detail on the failure)

If you see any different LED status lights displayed, or if you have any questions about the examples shown above, then please contact the Customer Support Team for advice at: support@em-trak.com

Alternatively, connect your B921, B922, B923 or B924 to the latest version of proAIS2 to check the diagnostic status of your unit.

The data captured in a log file will help us diagnose any fault. Can you please follow the instructions below:

  • Connect the unit via USB to a PC or laptop and apply 12-24V
  • Open up proAIS2 configuration software
  • Connect to the AIS unit
  • Go to the Serial Data tab
  • Select Log To File
  • Save the log to a location
  • Select the Diagnostics tab
  • Leave the unit transmitting for a duration of 30 minutes.
  • Stop logging and then send us the log file via email to support@em-trak.com

The pin-out for the B900 power/data cable is below:

B900_Series_PinOuts.jpg

You will need to ensure you use a suitable USB cable when connecting to your PC or laptop. There are two different types: power and data, and power only. The B900 Series requires a power and data USB cable, so using a power only cable will not allow detection or communication.

Unfortunately there is no way to determine the type from the appearance of the USB cable itself, so if you are unsure we would recommend specifically purchasing a power and data USB cable.

By default any data received on port 1 will be output on port 2 and over Wi-Fi / Bluetooth.
Also by default any data received on port 2 will be output on port 1. To multiplex that data received on port 2 over Wi-Fi / Bluetooth as well, please send the following command:

$PSMT,0,3,0x2C75B2FA,0,nvseti “nmea2mux”^2C0x5^2C2^2C0^2C0,0*7C

The command can be sent via the Serial Data tab in proAIS2.

AIS tracking sites get their data from AIS receivers that are installed along coastlines as well as satellites. Satellites receive a very low percentage (<2%) of transmissions from standard AIS transceivers and have many blind spots. Therefore tracking sites do not provide full coverage, at times their reception range is variable, may drop out entirely and their data refresh rate cycles and latencies can be very slow.

The best way to check your AIS is working correctly is to ask a nearby vessel with AIS if they can see you.

FAQ

Frequently asked questions

We are aware of an issue currently affecting some Android users of the Connect-AIS application. Our technical team is actively investigating the cause and working to restore full functionality as quickly as possible.

In the meantime, you may use our configuration software proAIS2 on your Windows PC or MAC OS via the USB data cable to configure your unit and see other diagnostics information.

How To Use ProAIS2 – https://productsupport.em-trak.com/hc/en-gb/articles/28856240027165-How-do-I-use-proAIS2

We sincerely apologize for the inconvenience this may cause. In the meantime, we kindly ask for your patience. Updates on the resolution will be communicated as soon as they are available.

You may occasionally see ‘TX Attempt failed (msg 18)’ or ‘CP busy’ appear in the Messages field of proAIS2.

The B921/B922/B923/B924 all operate using CSTDMA – a ‘carrier sense’ system. They have to find a free slot to transmit in by listening just before transmission to check the slot is empty.

When a transmission is scheduled a block of 10 potential slots is selected. It will attempt to transmit in the first of these slots. If the slot is busy the ‘CP busy’ (meaning ‘candidate position busy’) message will be output. It will then try again in the next slot, and so on for the remainder of the 10 slot block. It is quite normal to see ‘CP busy’ messages in an area where other AIS vessels are operating. It simply means the first slot selected was busy. 99% of the time the transmission will be successful in one of the other 9 slots.

So long as the indicator remains green transmissions are occurring on schedule. If transmissions can’t be made because the AIS environment is simply too busy the indicator will turn amber.

The B922 / B924 Bluetooth interface uses the Classic SPP (Serial Port Profile) – this is a standard method of replicating a wired serial connection and is used by many applications including Android, Windows, and Raspberry Pi.

Apple removed support for Bluetooth SPP from iOS, opting for a proprietary authentication method instead, so unfortunately the B922 / B924 are not recognised as Bluetooth devices.

CONNECT-AIS allows your smartphone to securely connect wirelessly to your B922 or B924, configure it and automatically monitor its health and performance.

The Android APK version of CONNECT-AIS can be downloaded from – https://em-trak.sharefile.com/public/share/web-s803b48ccedad4db9abae5b7c406a1644

The iOS version of CONNECT-AIS can be downloaded from the App Store – https://apps.apple.com/us/app/connect-ais/id1507169676?ign-mpt=uo%3D4en

*If you’re having trouble downloading CONNECT-AIS using the above link, please search for it using the Play Store app on your mobile device instead.

The Access Point mode default password for the B922 / B924 is emtrakais

This can be changed using the Wi-Fi tab of proAIS2, the configuration tool.

If you’re using the default Wi-Fi configuration on your B922/B924 it will be identified as ’em-trak’ on the latest version of the Navionics Boating app.

Otherwise, please follow the steps below to add the B922/B924 manually:

  • Connect to your AIS SSID from your Android or iOS Wi-Fi Settings page
  • Enter the password when prompted(found in your packaging or on the WiFi tab of proAIS2.)

  • Enter your Port number (Default: 5000)
  • Click Save
    The app should start receiving data

Note: You will also need to enable Location and Local Network in the Navionics app settings.

While each settings may be different, the above network information will apply to any other navigational applications such as, InavX, Aqua Maps, TimeZero, etc.

Establishing a connection

To connect to proAIS2 you will need to select the relevant device (usually ‘AIS Class B Transceiver’ for Windows and ‘AIS Virtual COM port’ for macOS) from the drop down menu at the top of the screen before pressing the ‘Connect’ button. If there is no suitable device to select, please ensure the USB cable is securely connected and that the appropriate LEDs are illuminated to indicate it has initialised. If you are still unable to connect to proAIS2 after verifying the connection please contact support@em-trak.com for assistance.

‘Configuration’ tab

Vessel Details:

You will need to populate these fields using the details from your ship license.

The MMSI number will be the same as the one issued for your VHF radio. If you have not been issued with an MMSI number you will need to contact your local authority. Please contact support@em-trak.com if your MMSI number has already been configured and you need to change it. The remaining vessel data can be edited using proAIS2 once configured. Configuration of the call sign is not required if you do not have one.

Ship’s Dimensions and GNSS Antenna location:

Enter the position of your GPS antenna (in metres) in reference to the four dimensions of your boat. If your unit is using its internal GPS antenna you will need to enter the position of your unit.

Configure Baud Rates:

This setting controls the speed at which data is output from the NMEA 0183 port(s). You will need to ensure it matches the baud rate of the connected equipment (for example, a chartplotter or VHF radio). Typically, chartplotters require 38,400 baud and VHF radios require 4,800 baud. AIS data should not be configured for output at baud rates lower than 38,400 – this is because messages may be dropped when travelling through areas of high traffic where there is a lot of data to process.

Output GNSS Sentences:

Tick the boxes as required to output the GPS sentences over the NMEA 0183 port(s). This will usually be defined by the external equipment you’re connecting to, but if unknown RMC is typically required to provide position and SOG/COG. If you require GPS data (PGNs) to be output over the NMEA 2000 port you will need to tick the RMC box.

GNSS configuration:

This setting controls the combinations of satellite constellations which are used to get a position fix. It is not supported by the B100, B300, or B330 as they use GPS only.

Long range broadcast:

This setting enables/disables the transmission of Message 27, used for long range detection. It’s transmitted on a different channel (frequency) and typically received by satellites. This proAIS2 feature is supported by Class B SO products only.

Please note that any applied configuration will need to be saved by pressing the ‘Write Configuration’ button.

‘GNSS Status’ tab

Use this tab to check the performance of your GPS antenna. This is particularly useful if you’re unsure where you need to mount your unit if it uses an internal GPS antenna. A good GPS fix is 30-40dBHz, although this may be difficult to achieve if your unit is using an internal GPS antenna and there’s an obstruction interfering with the signal.

‘Other Vessels’ tab

This tab shows the vessels in range. The vessels can be sorted by selecting the appropriate parameter at the top of the field.

‘Diagnostics’ tab

Checklist:

If your unit is fully configured and installed correctly every parameter should have a green tick against it.

Internal Data:

This field displays software versions, serial numbers, and operational/performance data. You may be requested for this information if you contact em-trak customer support for assistance.

‘VSWR’ is Voltage Standing Wave Ratio, and is an indicator of VHF antenna performance. A good VSWR is 3:1 or less, and can be affected by factors such as length or quality of cable and type of VHF antenna connected. If it exceeds the threshold a red cross will appear against AIS Antenna in the checklist field.

‘Power supply voltage’ reports the voltage received at the unit. There may be a small drop in voltage between the battery / power source and the unit, depending on the length of cable. External power (12-24V) is required for the unit to receive and transmit.

Status:

Reflects the LED indicator status on your unit. Select the ‘Silent Mode’ button to enable / disable silent mode, where the blue LED will illuminate if enabled.

Statistics:

Displays the number of messages that have been received and transmitted.

Messages:

Occasionally messages will be output in this field depending on the operational status of your product.

Class B/CS products routinely output ‘CP busy’ or ‘TX attempt failed’ messages; these are normal and relate to the way that Carrier Sense operates, where it needs to listen out for a free slot before it can transmit. You may also see a message relating to RX1 / RX2 and DSC; this is also normal and indicates when one of the receivers is monitoring the DSC channel on a regular, time-shared basis.

Alarms:

This field displays all active alarms. The alarm will be indicated with a corresponding red LED, either flashing (high VSWR) or solid (other hardware-related failure). If the conditions change and the alarm is no longer active, it will disappear from the list and the red LED will stop.

‘Wi-Fi’ tab

Use this tab to configure the W-Fi interface on your unit. The configurable parameters will differ between the B330 / B360 products and the newer B200 / B900 Series products; the specific details are covered in the product manuals. This tab is only available on products that support Wi-Fi.

As with the vessel data configuration, you will need to press the ‘Write Configuration’ button to save any changes.

‘Serial Data’ tab

Raw serial data is output on this tab. It can also be used to log the serial data to a file (which may be requested for diagnostic purposes if you contact em-trak for support), and there’s a field to enter command(s), if you have requested a configuration that isn’t supported directly by proAIS2.

‘VDR’ tab

Your position is automatically logged every time your vessel moves more than 10 meters, and this tab can be used to download that data from a selectable date range. The VDR feature is only supported on Wi-Fi products, and this proAIS2 tab is currently available for the B330 and B360 only.

If you have a question relating to proAIS2, and it isn’t covered in this article, please contact support@em-trak.com

Establishing a Connection

iOS – Wi-Fi
Connect your phone to the AIS unit’s Wi-Fi network using Settings > Wi-Fi. CONNECT-AIS uses the default IP address 192.168.2.1 and port 5000. Enter the unit’s Wi-Fi password when prompted.

Android – Bluetooth
Enable Bluetooth and open CONNECT-AIS. Bluetooth pairing is available for 5 minutes after the unit is powered on. If this window has expired, completely remove and reapply power, including USB. Previously paired devices do not need to be paired again.

Open CONNECT-AIS, select your AIS device, and enter the last four digits of the unit’s serial number if prompted.

If you cannot connect, contact support@em-trak.com.

Your Vessel Details

Select Configure your AIS Transceiver and enter the vessel information from your licence.

If you do not have an MMSI number, contact your local authority. If the MMSI has already been programmed and needs changing, use the MMSI change option in the app or contact support@em-trak.com for assistance.

Other vessel details can be edited at any time using CONNECT-AIS.

Your Vessel Dimensions

Enter the GPS antenna position in metres relative to the vessel dimensions. If using the internal GPS antenna, enter the position of the AIS unit itself.

Check the information carefully before confirming.
