Glossary AIS Universal Shipborne Automatic Identification System. A system of transceivers installed on vessels which send continuously updated navigation information. An AIS receiver or transceiver is used to monitor these transmissions and the AISWatchMate is used to display this information and trigger alarms when there is a risk of collision. BRG / Bearing The location of another vessel typically expressed as true or magnetic degrees.
be used to find additional registration information for a particular vessel. HDG / Heading The course a vessel is steering. MMSI Maritime Mobile Service Identity. Used as a radio identifier for each vessel with digital radios such as an AIS transceiver. Vessels may also transmit their name to facilitate easier identification. These transmissions occur at a different interval than position information and as a result the name may not be immediately available. All AIS transceivers require a unique MMSI.
Introduction The AISWatchMate is a device which provides information to assist in avoiding collisions at sea. It works by receiving and transmitting data as part of the Universal Shipborne Automated Identification Systems (AIS). The AIS system uses two dedicated VHF channels designated for this purpose and with the installation of the AISWatchMate to receive signals from other AIS-equipped vessels you can view this information.
allows you to view the target list and also examine each target in detail. By default, the target list is ordered by priority. You can disable priority ordering if you wish. However, by viewing targets in a prioritized fashion you can focus your interest on the targets most likely to pose a collision risk first. Similarly, whenever a target triggers an alarm you don't have to scroll to find it. The target is displayed immediately with an indication of the cause of the alarm.
Bearing The bearing to each target is also displayed. The bearing may be shown as magnetic to facilitate quick visual identification using a compass or binoculars. However, if you wish you can change a setting to display bearings in degrees true or relative to your vessel's current heading. Closest point of approach (CPA) The CPA is the closest a target will come to your vessel if both your vessel and the target maintain their existing course and speed.
vessels. Always check to see how long it has been since an update was received from a vessel when relying on this information, particularly in close situations. You do this by examining the “age” of the target. See the target display section for more details. The AIS system also includes messages broadcast from other vessels and shore stations which may be used to send navigation warnings, weather information, etc.

Installation Requirements The AISWatchMate requires a suitable VHF antenna which must be supplied by the user and a clear view of the sky for the built-in GPS or an external GPS antenna. The following are required for installation: ● Various countries have regulations requiring a VHF radio license to operate an AIS transceiver. Check with your local authorities to determine the requirements for your area. ● You must have an assigned MMSI and Call Sign for your vessel.
equipment. However, the GPS data produced by the AISWatchMate is available for use by other optional equipment connected to the NMEA output. Mounting the Display Your AISWatchMate is supplied with a trunnion mounting bracket if you wish to mount it above or below a shelf or other support. You may also mount the unit by cutting a hole in an instrument panel and mounting it flush. Included is a template you can use to cut the hole and drill four additional holes for the required fasteners.
● Place your antenna as high as possible and at least 2-3 metres (6-10 ft) above the water surface. ● Place your VHF antenna as far as possible from other antennas and metal structures, especially other VHF, HF and radar antennas. It is not recommended to place the VHF antenna directly alongside a mast or another VHF antenna such as on a mast-head. GPS Antenna Installation The AISWatchMate has an internal GPS patch antenna facing upwards. This antenna requires a clear view of the sky.
● It is not necessary to change any settings when using the optional Vesper Marine GPS antenna. Simply connect it to the TNC connector on the back of the unit. Considerations when using the internal GPS patch antenna: ● The AISWatchMate should be situated so it has no metal obstructions over the top. The antenna is located in the back “bulge” area at the top of the unit facing upwards. ● Avoid placing your hand or body over the antenna area as this may reduce satellite signal strength.
Power/Data Cable Wiring A 2m (6.5') power/data cable with attached connector is supplied with the AISWatchMate. You may extend this cable as necessary. It is recommended that any splices made in the cable be done in a weather tight area to prevent corrosion and failed connections. Consult a marine electronics technician if you have any difficulties or concerns about installation.
Blue External alarm. When the alarm is triggered and the external alarm is enabled this wire will have the input voltage (from the red wire) applied. You can use this to provide power to an external buzzer, light or other signal device. Maximum current is 150mA. If your device requires more current then an external relay must be used. Others All other wires are not used. Leave them unconnected.
Connecting an Optional Heading Sensor or Chart Plotter Connecting an Optional External Alarm - 31 -
Using a Relay to Control a High Current External Device When your external device requires more than 150mA you must use an external relay. Ensure a spike suppression diode (eg. 1N4001) is either provided by the relay or fitted externally. You should also provide a fuse of the appropriate value to protect against overload.
GPS Backup Power To speed the time-to-first-fix, do not disconnect or switch off the power supply to the AISWatchMate. If you do switch off the power supply it may take longer for the built-in GPS to acquire satellite data and a position fix. You can switch the unit off using the power button on the front and it will continue to maintain the GPS almanac data as long as the power supply to the AISWatchMate is maintained.
Using your AIS WatchMate when powered by USB It is possible to use your AISWatchMate when powered only by the USB connection to your computer. This is useful for configuring your AISWatchMate at home prior to installation on your vessel. This also allows you to use it as an AIS receiver and GPS without connecting to an additional DC power source.

Important Notice You cannot change the MMSI number once it has been saved in the unit. Enter the number carefully and only use an assigned MMSI for your vessel. If you need to change the MMSI number in your unit you must contact an authorized dealer or Vesper Marine. The AISWatchMate will not transmit your data until your MMSI has been entered. When you enter your MMSI number and press the OK button to save it, the following screen is displayed. Press the Yes button to proceed and save your changes.
Power Button Press the power button momentarily to turn on the AISWatchMate. Press and hold the power button for 2 seconds to turn it off. While the AISWatchMate is turned on, pressing the power button momentarily allows you to change the display brightness. One Minute Startup Time The AISWatchMate will not begin to transmit for one minute after it has been switched on. This startup time is required to determine background noise levels on the AIS frequencies.
Display Screens Home Page – Situation Display The home page displays targets using a graphical situation display similar to a radar. The display is oriented either Heading-Up or North-Up depending on the profile and settings. If heading data is not available for your vessel, then it is oriented course-up or north-up. The heading or course may be displayed in magnetic or true degrees depending on a setting in setup mode. You must have a valid GPS fix for any targets to be shown on the situation display.
Range Rings The outer range ring corresponds to the current plotting range. The inner range ring is ½ the plotting range. If the guard alarm is enabled an additional dotted range ring is drawn to indicate its position. Plotting Range The plotting range may be changed by using the Menu button. Target count The count of all targets includes targets which are not visible on the plotting display because they are either out of range or have not sent a position report yet.
Icon Meanings An ordinary target. The triangle points in the direction of the target's heading (or course if heading data is not available for the target). A dangerous target. This target meets one or more of your alarm criteria. An aid to navigation. A dangerous aid to navigation. This target meets one or more of your alarm criteria. A search and rescue transponder (AIS SART). This symbol appears around a target to indicate it is the currently selected target.
! Indicates your AIS data is not being transmitted. In order for your AIS data to be transmitted you must have configured the MMSI and the GPS must have a position fix. Other reasons are silent mode has been enabled or a base station has commanded your AIS transceiver to enter “quiet mode”. You can use the AIS Status screen to determine the reason. Important: The AISWatchMate will not begin to transmit for one minute after it has been switched on.
Note: Because the order of targets shown with the Next and Prev buttons depends on their priority, pressing Next and Prev may not always bring you back to the same target if their priorities have changed. This occurs more frequently when targets or your own vessel are making course changes. Main Menu The Menu button on the home screen situation display allows you to select an option from the table below.
Fleet List Displays a list of members in your fleet. You can remove members from this list. Members are added to the list from the target details menu when you are viewing a target. This option is only available when one or more targets has been added to the fleet list. You can add a target to the fleet list using the Menu button when the target you wish to add is being displayed. Message List Displays the list of received safety messages. See the Safety Message section for more details.
of communicating a MAYDAY. Anchor Watch Displays the Anchor Watch screen. Use this screen to mark your anchor location and observe your vessel in relation to your marked location. You may also enable an alarm if your vessel moves outside a preset circle around your anchor location. Setup Displays the settings you can change. Also allows you to customize the alarm and filter settings for the current profile. See the Setup Mode section for more details.
Target List The target list contains all non-filtered targets. You can scroll through the list to select a target to view in detail. By default, the target list is continuously ordered by priority. The priority of a target is based on its CPA, TCPA, range, and speed. Higher priority targets are shown at the top of the list. In setup mode you can disable this feature if you wish and targets will be displayed in the order they were first received.
If the target and your vessel are not converging, such as when they are moving apart, the target's CPA is blank. If you wish, in setup mode you can configure the target list to display each target's speed over ground (SOG) rather than CPA. When this screen is displayed, you can use the following buttons: ▲ Scroll your selection up. This button is only active if it is possible to scroll up. ▼ Scroll your selection down. This button is only active if it is possible to scroll down.
Target Display The target display screen is shown when you select a target from the target list or situation display. This screen contains detailed information about the target. The information displayed will vary depending on how much data has been received from the target and the type of target. AIS data for a target is received in several types of messages and those messages may be received at different times.
If the target and your vessel will not converge, such as when they are moving away from each other, the CPA is shown as None and TCPA is not displayed. When the TCPA is greater than one hour it is displayed in minutes without the seconds (eg. 123min). When the target display screen is shown due to an alarm condition the reason for the alarm will be blinking (eg. RNG for a guard alarm and CPA for a CPA alarm). The blinking stops when the alarm is muted or the target is no longer in an alarm condition.
While the target screen is displayed, you can use the following buttons: Menu Allows you to disable or re-enable alarms for this target. Also allows you to add the target to your fleet. A target which is a member of your fleet is shown with a circle around its icon on the situation display. Mute Disable alarms for this target. This function is only active when an alarms is sounding for the target. See the section on alarms. CPA Display the relative position of the target at CPA.
CPA Graphical Display When a target is converging and has a CPA shown, the CPA button is available on the target display. This button brings up a graphical plot showing the relative position of the target at the time of CPA. The display is oriented either Heading-Up or North-Up depending on the current profile settings. If heading data is not available for your vessel, then it is oriented course-up. The heading or course may be displayed in magnetic or true degrees depending on a setting in setup mode.
Important notes: 1. No other targets are shown on this display. Only the current target and your vessel are displayed. 2. The plotting distance shown on the screen between your vessel and the target is always the same regardless of the actual CPA. Always use the CPA value displayed to confirm the expected distance at the time of closest point of approach.
Safety Message List The message list displays safety messages received from other vessels and shore stations. Safety messages are free-form text and may pertain to emergencies, port operations, hazard warnings, weather or other important information. They may be broadcast to all AIS-equipped vessels within range or may be specifically addressed to your vessel. You can send a pre-programmed MAYDAY safety message to all AIS-equipped vessels within range by selecting the Send MAYDAY option from the main menu.
When the safety message list is displayed, you can use the following buttons: ▲ Scroll your selection up. This button is only active if it is possible to scroll up. ▼ Scroll your selection down. This button is only active if it is possible to scroll down. Select Display the safety message. Home Return to the situation display.
Safety Message Display The message display screen is shown when you select a message from the safety message list. The sender and full text of the message is shown on this screen. When a safety message is first received, this screen is automatically shown.
When the safety message screen is displayed, you can use the following buttons: ▲ Display the previous safety message. This button is only active if it is possible to scroll up. ▼ Display the next safety message. This button is only active if it is possible to scroll down. List Display the list of all safety messages. Home Return to the situation display.
Fleet List If targets have been marked as being members of your fleet, they may be displayed in the fleet list. Use this list to view your fleet or remove members from your fleet. To add a vessel to the fleet list, use the Menu button on the target details screen. Weather Reports If meteorological / hydrographic messages are transmitted in your area they will be placed in a list for you to review. The list shows the latitude and longitude of each reporting station.
AIS Status Display This screen displays information about your AIS transceiver's status. In the box at the top of the screen the tick marks indicate the primary operational state. If any items require attention they will be indicated by ! If this symbol is shown, the AISWatchMate is not transmitting your vessel's AIS data.
A description of each item is shown below. MMSI Configured You must configure your AISWatchMate with a valid MMSI before transmission can occur. See the Configuration section. Silent Mode is Off One of three conditions: 1. You have enabled silent mode. See the Silent Mode setup option under AIS Transceiver Setup. 2. You are running on USB power only. It is not possible to transmit when powered solely by USB. 3. Your transceiver has been commanded by a base station to enter “quiet mode”.
Position Report Sent Indicates that the last scheduled position report was sent. It is normal to occasionally miss a position report when operating in busy areas. Frequency The radio frequency assigned to each channel. You cannot change this value. Mode The operating mode for each each channel. You cannot change this value. RSSI The background noise level for each channel. This is for informational purposes. Rx Msg Count The number of AIS messages that have been successfully received on each channel.
Using the Anchor Watch The anchor watch may be used to sound the alarm if your vessel moves outside a preset circle. To use the anchor watch, follow these steps: 1. Prior to anchoring, select “Anchor Watch” from the main menu. 2. Adjust the size of the preset circle by using the Dist button. This button determines the alarm distance from your anchor (or radius) of the circle. The distance may be changed at any time. 3.
Use the following buttons from the Anchor Watch screen: Reset Reset the anchor location to your current position. Dist Adjust the alarm distance (radius of the circle). Enable Turn the alarm on or off. Disable Home Return to the situation display. Note: If the alarm is enabled, it will remain active.
Use of Heading Data If heading data is available, your vessel is shown oriented by its heading. If heading data is not available, your vessel is shown oriented by its course and it is likely it will not correspond accurately with reality. It is also normal for the orientation of your vessel to fluctuate or point north in this circumstance.
Icon Meanings Within Anchor Watch Your vessel. The reference position of your GPS antenna is not known or heading data is not available. Your vessel. The dot at the bow indicates that your position is referenced to the bow of your vessel. The alarm is enabled and will sound if your vessel moves outside the circle. Adjust the distance from your marked anchor location by using the “Dist” button. Note: To prevent nuisance alarms, the alarm does not sound immediately when your vessel moves outside the circle.
Displaying Information About your AIS WatchMate You can display the following information by selecting About your AIS WatchMate from the display settings menu. This information is provided for reference and technical support purposes.
Target Filters There are several filters which allow you to control which targets are included in the target list and may be displayed. These give you the ability to limit the target list and are most useful when operating in areas with large amounts of vessels. Any filter can be turned off. If all filters are turned off, then all possible targets are included in the target list and all targets may trigger alarms. When a target is filtered, it is not shown in the target list.
stationary or moving very slowly. It is most useful when there are large numbers of anchored or moored vessels in your operating area. It is not recommended to set this value too high since it may filter out all targets and alarms. Target CPA filter Specifies the maximum CPA allowed for a target to be visible. All targets with a CPA greater than this value will be filtered and not shown.
Target Alarms There are two types of target alarms provided by the AISWatchMate. They are called Guard Alarm and CPA Alarm. Each alarm applies independently to each target. This means that alarms may be silenced for some targets but will still remain active for other targets. When an alarm is sounded, the display immediately shows the target that has triggered the alarm. Pressing the Mute button silences the alarm and all subsequent alarms for that target only. Other targets may still trigger alarms.
Guard Alarm The simplest type of target alarm is the guard alarm. It is triggered whenever a target is within range of the alarm setting. It works similar to a radar guard alarm. You select the range for the alarm and if any vessel is currently within that range, in any direction around you, the alarm is triggered.
guard alarm to “ALL”, then the alarm will sound regardless of whether GPS data is available or not. You can use this feature if you have not connected the AISWatchMate to a GPS but wish to be alerted when targets are present. This is the only alarm setting that will work when GPS data for your vessel is not available. CPA Alarm A CPA alarm is triggered when a target meets the criteria you have established. When a CPA alarm occurs, the target that caused the alarm is displayed.
This allows you to suppress alarms for targets which are predicted to come close but not for a long period of time. CPA alarm – The speed (in knots) which the target must be target speed moving in order to trigger a CPA alarm. If the target is moving at less than this speed then no CPA alarm will be triggered for this target. This allows you to suppress alarms for targets which are either stationary (anchored or moored) or are moving very slowly (drifting, fishing, etc.).
Profiles To organize the filter and alarm settings there are four “profiles”. These allow you to quickly switch between various settings when your situation changes. This is done by selecting the active profile from the main menu on the situation display. Each profile is provided with a default value for its settings, but you can change these values and they will remain at your selected settings until you change them again, even after you turn the unit off.
Setup Mode Setup mode is entered by selecting Setup from the main menu on the situation display. In setup mode the list of available setting groups are displayed. Scroll through the list and select the setting group you wish to change. You may then follow the same procedure to select the specific setting you wish to change and a pop up box is displayed with the available options for that setting.
The default is to display CPA in the target list. However, if you are not using the target speed filter you may find it useful to display the target's speed instead. Sort targets by priority Displays targets sorted by their priority. A target's priority is based on its CPA, time until CPA (TCPA), range, and speed. You can choose to disable this setting and targets will be displayed in the order in which data was first received from a target.
In addition, if position information is not available a message is shown on the situation display, target list, and target display. Note: If your vessel's position is not available then alarms will not be triggered. Safety message handling Choose whether to enable or disable an alert which sounds when a safety message is first received. This alert sounds the alarm with three short beeps. If the same message is received again it does not sound the alarm.
you select External-only and an external alarm is not fitted. Test the alarm Allows you to test the internal or external alarm to ensure it is working properly. Navigation Settings Course and heading mode Select how to display course and heading data for targets. This also affects how your vessel's heading is shown on the situation display. You may choose between True or Magnetic. Bearing to target mode Select how to display bearings to targets.
heading data. Note: If heading data is not available then relative bearings will be shown relative to your course rather than your heading. Note: If magnetic variation is not provided by your GPS or heading sensor then magnetic bearings will be shown as true. Default display orientation Select the orientation (Heading-Up or NorthUp) you wish to use by default. This orientation is used if a profile doesn't override this setting.
purposes. When the simulation is running, actual GPS positions and targets are not displayed. Display Settings Brightness Adjusts the brightness of the display and buttons. You can also adjust the brightness by momentarily pressing the power button. Contrast Adjusts the display contrast. Turn display off when idle Select the number of minutes after which the display is turned off. If the display is off and a target or message is received the display is automatically turned back on.

Metric or imperial Select the units (metres or feet) to use for displaying target dimensions. AIS Transceiver Silent Mode Enable or disable the AIS transmitter. This feature may be used in situations where you do not wish to transmit your vessel data.
values. Any settings you have changed will be reset and you will lose any changes you have made. When you select this setting a warning is displayed. To continue and reset all settings, choose “Yes” to “Are you sure?” and press “OK”. When you answer “Yes” or “No”, a message is briefly displayed confirming your choice. Settings Associated with Each Profile The following settings are associated with a profile selection.
Settings Group) will be used. This allows you to override the default for one or more profiles, for example setting the default to Heading-Up but overriding it to be North-Up when anchored. Target speed filter This specifies the minimum SOG (in knots) that a target must be moving to be included in the target list. Targets moving slower than this speed will be filtered from the target list and will not appear. Use this filter to eliminate slow or stationary targets from the target list.
in the target list. Targets farther away will be filtered from the target list and will not appear. Use this filter to eliminate distant targets from the target list. Alarms are not triggered for filtered targets. The total count of filtered targets is displayed on the situation display. Selecting “OFF” disables the target range filter. It is not recommended to set this value too low since it may filter out all targets and alarms.
Selecting “All Non-converging” indicates that all targets that do not have a CPA (meaning they are not on a converging course) will be filtered. If this setting is lower than the “CPA alarm Target Speed” setting a warning is displayed to indicate you may be filtering more targets than you intend. Target TCPA filter This specifies the maximum TCPA value a target can have and still be displayed. Any targets with a TCPA greater than this value will be filtered.
exists. Guard alarms are most useful when operating where few targets are expected to be encountered and you wish to be notified there is “somebody out there”. Selecting “OFF” disables the guard alarm. Selecting “ALL” indicates that all targets regardless of their range will trigger the guard alarm. Important note: “ALL” is the only alarm setting that operates without GPS input. CPA alarm Triggers a CPA alarm for any target which will come this distance or closer to your vessel (in nautical miles).
This allows you to indicate that you only want alarms for targets which pose a risk of collision in the “near future”. Selecting “OFF” allows a CPA alarm to be triggered regardless of the time until CPA if it also meets the specifications of the other CPA alarm settings. This setting is only available if the “CPA alarm” setting is not set to “OFF”. CPA alarm - Target Speed This value specifies the minimum SOG (in knots) that a target must be moving for it to trigger a CPA alarm.
This setting is only available if the “CPA alarm” setting is not set to “OFF”. CPA alarm - Your speed This value specifies the minimum SOG (in knots) that your vessel must be moving for a CPA alarm to be triggered by other vessels. If a target meets the other specifications for a CPA alarm but your vessel is not moving at least this fast, no alarm will be triggered. This setting allows you to indicate that you don't want alarms when you are stationary or moving slowly.
Built-in Integrity Test (BIIT) The AISWatchMate continuously monitors its transceiver performance. If it detects an error condition you will be notified with a message box and the alarm will beep briefly. For certain messages you are able to press the Confirm button to acknowledge the situation and prevent the message from reappearing. However, this is not possible with all messages and some will reappear whenever the error condition is detected. An example message box is shown below.
Device Alerts The AISWatchMate will display device alerts (sentence $xxALR) received from other instruments. These alerts may indicate operational status or problems. When a device alert arrives, the message associated with it is displayed and you are given the opportunity to send a confirmation back to the device that generated the alert. This tells the device that you have acknowledged the situation. The specific types of alerts and messages are determined by the attached devices.
