AIS tracking sites get their AIS data from AIS receivers that they have randomly installed along coastlines wherever possible as well as from satellites equipped with AIS receivers. 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 X100 is working correctly is to ask a nearby vessel with AIS if they can see you.

Chartplotters / MFDS / Radar displays. Whatever you want to call them, they’re often the focal point of any navigational setup on a vessel so it makes sense to connect AIS receiver or transceiver to get an idea of the bigger picture around you. That being the case, we’re often asked if certain plotters are compatible with our AIS devices and if so, how do you go about connecting one of our devices to an existing plotter.

Selection of the VHF antenna is critical to achieving the optimum receive and transmit range. We would recommend choosing an antenna that is tuned to cover the AIS & VHF channels range of 156MHz to 162MHz.

Vessel construction

The way your vessel is built can affect GPS performance. For instance, being near heavy structures like a bulkhead or inside a larger boat might reduce the signal. Materials like steel, aluminium, or carbon can also impact how well the GPS works.

Check list

The check list will help you think through the placement of your hardware, cable routing, any potential interference, as well as any issues with Wi-Fi drop out, VHF and GNSS signals.

If you’re not sure how to do this, ask someone with experience in installing this kind of hardware.

Take a moment to go through the list below, this will help make sure you choose the right locations for installing the equipment.

Choosing the best locations helps your hardware perform at its best and avoids potential problems down the line.

Controls

Before you start using the X100, take some time to familiarise yourself with the controls.

Take some time to familiarise yourself with the fist-mic controls.

Initial start-up

Once the planning and installation is done, you’re all set to start enjoying everything the X100 has to offer.

Start by powering on the X100 and enter your operational region, input your MMSI number, and download the app onto your smart device.

You will then be asked to connect your device to the X100 by scanning the QR code shown on the screen, the devices connect over Wi-Fi.

On-boarding

At this point, the  should be installed with the app downloaded and working on your smart device.

Firstly you will be asked to enter the captains name and pin number. Next, you’ll need to enter the static data, which can be done using either your smart device or the X100.

The static data includes:

• Your region – Under this option, you’ll find three choices: U.S, Canada and International. Choose the location in which you’ll be operating. If you are operating in the U.S., your region is entered automatically.
• MMSI number – If you are in the United States, this will be entered by your dealer or another qualified person. Without this number, features like DSC calling and AIS VHF will not be available.

If you’re unsure where to find the MMSI or if you don’t know what it is, check your VHF radio license. It should match the MMSI used for your VHF/DSC radio.

• Vessel Details: The vessel details include your ship’s name, call sign, and ship type. Additionally, you’ll need to reference the dimensions of the GPS antenna location that connects directly to the X100.

  Below is an easy to follow break down showing how to enter the GNSS/GPS antenna location accurately:

1. First, measure the distance from your antenna to the bow and enter this value for Position A.
2. Next, measure the distance from your antenna to the port side and enter this value for Position C.
3. Then, subtract measurement A from the total length of your boat and enter this value for Position B.
4. Finally, subtract the Position C value from the total beam of your vessel and enter this value for Position D.

Connecting further devices to the X100

At this point you should have finished the on-boarding process. If you haven’t already, complete that process and come back here. Click here to learn how to do this.

If you’re setting up a new smart device, you’ll want it to join the same network as your X100 for seamless access. To join the network simply press the JOIN WI-FI softkey on the VESSEL screen.

OUTPUT SENTENCES communicate with your chart plotter via NMEA, providing accurate location data for positioning. They also help troubleshoot real-time location issues, ensuring smooth navigation.

Below shows you how to enable to X100 to generate output sentences.

DSC

Under DSC you have the freedom to configure the X100 to automatically respond to messages, requests, enable or even toggle certain features on or off.

An automated procedure is something that you can configure the X100 to do automatically, like respond to position requests by sending your co-ordinates without any manual input.

These settings allow you to customize how your system handles distress, test messages, position requests, and more, ensuring better management of communications in varying situations.

Below shows you how to adjust the DSC settings.

• AUTO ACKNOWLEDGE TEST MESSAGES You can configure the X100 to automatically reply to all incoming test messages, so there is no manual input from you.

  

• NON AUTOMATED PROCESS TIMEOUT You can configure a timeout to end any processes that doesn’t end automatically like making or receiving a DSC or VHF call.

  

• NON DISTRESS AUTOMATED PROCESS TIMEOUT You can configure a timeout to end any processes that are not distress related such as group calls.

  

• RX DISTRESS AUTOMATED PROCEDURE TIMEOUT This setting lets you adjust how long the X100 waits before finishing the incoming distress process. A warning message will appear on the screen ten seconds before the timeout is triggered, giving you a heads-up. Once the timeout completes, the distress request process automatically ends.

  

• COMMUNICATIONS AUTOMATED TIMEOUT PROCEDURE This is the time limit set to prevent another process from interrupting the task you are currently performing.

  For example, if you are on a DSC call and you receive a position request, you will not receive a notification until the set timeout elapses. You will however have an option to accept and overwrite the timeout or log the call and return to it later.

  

• AUTO CHANNEL CHANGE This lets you configure whether or not the X100 will change to another channel automatically when receiving an incoming call, or request.

  

• AUTO ACKNOWLEDGE INDIVIDUAL CALL This lets you choose whether the X100 automatically accepts incoming individual calls or allows you to decide which calls to answer or ignore.

  

• AUTO ACKNOWLEDGE POSITION REQUESTS This setting allows you to enable the X100 to automatically reply, ignore or require a manual response to any incoming position requests with your current co ordinates.

  

• NMEA SENTENCE OUTPUT This feature allows you to configure the X100 to output NMEA sentences to any connected NMEA-compatible device, such as a chart plotter.

  

• DSC QUICK CALL: This allows you to enable or disable the DSC Quick Call function. For more information on how to make quick calls, click here or here.

  

   

MOB

You can EMBARK or DISEMBARK devices, and then ENABLE MONITORING of the embarked devices. Only embarked devices receive MOB alarms.

Enabling MONITORING is particularly useful when you’re keeping track of crew members with assigned devices. For example, if someone with a monitored device goes overboard or moves out of range, you’ll be alerted immediately, allowing for a quick response in case of emergencies.

Manage devices

MANAGE DEVICES enables you to EMBARK and DISEMBARK any crew members smart device that is already on the same wireless network as the X100, and to activate the MOB monitoring feature. Every time someone boards the vessel, you should EMBARK their device to enable this safety functionality. Likewise, when leaving, you should DISEMBARK the device to prevent any false MOB alerts.

Take time to make sure that the monitoring feature is enabled under ADVANCED, so that the embarked devices receive all MOB alerts. Click here to learn how to do this.

Below shows you how to easily EMBARK a device.

To DISEMBARK a single device, follow the same steps, but press the DISEMBARK softkey. To remove all devices at once, simply press the DISEMBARK ALL softkey. This ensures that only active devices are tracked, helping to avoid false MOB alerts.

Advanced

Under ADVANCED, you can turn enable MONITORING and adjust the MONITORING SENSITIVITY to control alert timing.

Before you enable monitoring, make sure that all of the applicable devices are embarked.

• Enable or Disable Monitoring: When MONITORING ENABLED is set to YES, you’ll receive alerts for any MOB incidents. Setting it to NO disables these alerts.

• Adjust Monitoring Sensitivity:  When MONITORING ENABLED is set to YES, you can set the MONITORING SENSITIVITY. Higher sensitivity makes the MOB alarm trigger more quickly but increases the chance of false alerts. Lower sensitivity reduces false alarms but may delay the alarm trigger.

  Below shows you how to enable MOB monitoring and adjust the alert sensitivity.

  

Audible alert

You can enable or disable the audible alarm that accompanies the MOB alert, if enabled the alarm sounds for the duration of the MOB alert.

By default the audible alarm is enabled.

From SETTINGS, select MOB, then AUDIBLE ALERT, you can use the arrow keys to ENABLE or DISABLE the audible alert.

Below shows you how to enable or disable to audible alert.

ATIS

ATIS is specifically designed for use in the inland waterways of RAINWAT (Regional Arrangement Concerning the Radiotelephone Service on Inland Waterways) countries. When ATIS is enabled, the DSC functions on the device do not operate. It’s important to remember not to enable ATIS when you’re in open water, as it could hinder your ability to use essential communication features. This ensures that you maintain effective communication and navigation capabilities in various environments.

Under ATIS, you can turn ATIS MODE ON or OFF and set your unique ATIS ID.

You must enter your ATIS ID first in order to enable ATIS MODE.

Setting your ATIS ID

You can obtain your ATIS ID from the same agency that issues radio operator licenses in your area. This helps to facilitate effective communication and navigation on inland waterways.

An ID typically starts with a 9, consists of 10 digits, and is entered only once. If you ever need to change your ATIS ID, contact your local dealer for assistance. This ensures proper identification and compliance with regulations in inland waterways.

Below shows how to you can easily enter your ATIS ID.

Once entered, the ATIS ID cannot be deleted or changed by you, so make sure it is entered correctly. If you need help contact support@em-trak.com.

Enabling and disabling ATIS mode

ATIS mode should only be used when navigating the inland waterways in RAINWAT countries. When ATIS is enabled, the DSC function on the X100 will not work. For this reason, it’s best not to enable ATIS while you’re in open water to maintain full communication functionality. This ensures you can use DSC for emergency and routine calls when needed.

To enable the ATIS mode you first must enter your ATIS ID, then go to SETTINGS, select ATIS and then MODE. You can use the arrow keys to toggle ATIS mode ON/OFF.

Below shows you how to easily enable ATIS Mode.

Alerts

Under ALERTS, you can set the limits and toggle the alerts for the following:

• Closest Point of Approach (CPA) and Time to Closest Point of Approach (TCPA) alarm: These alarms work together and cannot be toggled on or off individually. This means that both alarms are activated or deactivated simultaneously, ensuring coordinated alerts for approaching vessels and potential collision risks.

• CPA and TCPA THRESHOLD: The CPA THRESHOLD sets the minimum distance that another vessel can approach before an alarm is triggered, while the TCPA THRESHOLD indicates the time remaining until the vessel reaches the CPA limit.

• ANCHOR WATCH: This monitors your vessel’s position in relation to the anchor point. If your vessel drifts beyond the set ANCHOR LIMIT, an alarm will sound, and a pop-up notification will appear on the screen. This feature helps ensure that your vessel stays safely anchored and alerts you if it moves unexpectedly.

• ANCHOR WATCH LIMITS: While anchored and your vessel drifts beyond this set limit, an alarm will sound, and a pop-up notification will appear on the display. This visual and audio alert helps you stay informed of any unexpected movement while anchored, ensuring the safety of your vessel.

CPA and TCPA alerts

The X100 allows you to manage the CPA and TCPA alarms, you might want to turn these off if you’re navigating in busy waters.

In open ocean, you might want to set the CPA and TCPA to higher values. This allows the alarm to function more like a proximity detector, giving you early warnings about vessels entering a wide safety zone around your position.

Setting these alarms can help you stay aware of nearby vessels and avoid potential collisions by giving you a good warning before any chance of collision can happen.

Below shows you how to turn the CPA and TCPA alerts ON/OFF.

CPA and TCPA threshold

If you’re navigating in busy waterways or near other vessels, setting the CPA THRESHOLD ensures you’ll be alerted if another vessel is predicted to get too close, giving you enough time to take action and avoid a collision.

This allows you to define the safe distance around your vessel and receive alerts when other vessels come too close.

Below shows you how to set the threshold.

If you’re approaching a busy area or navigating through narrow channels, setting the TCPA THRESHOLD helps you monitor how much time you have before another vessel comes too close, allowing you to adjust your course or speed in advance.

This setting allows you to define how much time remains before both vessels reach the CPA, giving you ample warning to take any necessary action.

Below shows you how to set the threshold.

CPA Audio Alarm

The CPA AUDIO ALARM is a sound that alerts you when the CPA threshold is breached. For example, if another vessel gets too close, the alarm triggers to grab your attention immediately. You can configure the alarm to be audible or silent, depending on your preferences and environment.

Below shows you how to turn the alarm ON or OFF. 

Anchor watch

There will be times when you’re anchored that the current may cause your vessel to drift. You can set an ANCHOR WATCH alarm on the X100 that notifies you when you drift too far.

Once set, a virtual safety zone is set up around your anchor point. If your boat drifts beyond this area because of wind, currents, or other factors, ANCHOR WATCH will alert you with a pop-up or alarm. Make sure you turn on anchor watch after the boat is anchored and not drifting. It’s a great way to have peace of mind, knowing you’ll be notified if your vessel starts moving unexpectedly.

Below shows you how to turn ANCHOR WATCH ON or OFF.

Anchor re-centre

When you drop anchor, it’s a good idea to use the ANCHOR RE-CENTRE feature. For example, if your vessel drifts slightly due to wind or currents, this feature recalculates your position from the point the feature is activated. This helps ensure accurate tracking of your position while you’re anchored.

Below shows you how to re-centre your vessel.

Anchor threshold

When you activate ANCHOR WATCH, the ANCHOR THRESHOLD surrounds your vessel with your vessel in the middle. If the boat drifts beyond this set boundary, an alarm will sound, and a pop-up will appear on the screen to notify you.

Below shows you how to set the threshold.

Units

On the X100, you can adjust certain settings to suit your needs. For instance, you can choose the preferred way units for distance and speed are shown.

Sensors

Under SENSORS, you can view and adjust the BAUD RATES for different devices connected to the NMEA0183 ports. The baud rate determines the speed of data communication between your X100 and the connected sensors. Adjusting the baud rate helps ensure that data is transferred efficiently and consistently, matching the requirements of each sensor for optimal performance.

Baud rates

The baud rate is the speed at which data is transmitted over a communication channel. In the context of serial ports, 4800 baud means the serial port can transfer a maximum of 4800 bits per second.

The following baud rates are available for selection:

• 4800 – This is only really used for legacy devices that have slower data transfer.
• 38400 – This works well for communication between the X100 and a chart plotter.

These rates control how quickly data can be sent between devices, and choosing the correct rate helps ensure smooth and reliable communication between your X100 and connected sensors.

Below shows you how to set the baud rate.
