NOT ALL SHIPS CARRY AIS. The Officer of the Watch (OOW) should always be aware that other ships and, in particular, leisure craft, fishing vessels and warships may not be fitted with AIS. Any AIS equipment fitted on other ships as a mandatory carriage requirement may also be off based on the Master’s professional judgement.
Disposal of the transceiver and packaging Please dispose of this AIS transceiver in accordance with the European WEEE Directive or with the applicable local regulations for disposal of electrical equipment. Every effort has been made to ensure the packaging for the transceiver is recyclable.
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 Systems to monitor and control the transmissions of AIS transceivers.
AIS transceiver is to be installed must therefore possess a current VHF radiotelephone licence which lists the AIS system, vessel Call Sign and MMSI number. Please contact the relevant authority in your country for further information regarding ship’s radio licensing requirements.
This section assumes that the Oceansat transceiver has been installed in accordance with the instructions provided in the Installation section of this manual. Please read the warning notices at the front of this manual before operating the AIS transceiver. 3.1 Display and controls...
Operation 3.2 Turning the transceiver on The Oceansat transceiver does not have a power switch and is designed to be permanently powered. When power is first applied the display will show a splash screen followed by software version information. Each screen is shown for 5 seconds before the main operating screen is shown.

Operation 3.12 Handling alarms The Oceansat transceiver performs self checking functions continuously. If a self check fails an alarm will occur. Possible alarm conditions are listed in Table 2. Alarm condition Description Transmitter malfunction This alarm can occur if there is a fault with the transmitter or if the antenna VSWR exceeds allowable limits.
Operation From the alarm notification screen you have the option to immediately acknowledge the alarm by pressing the ‘ACK’ function key, or to view the active alarms list by pressing the ‘Goto List’ function key. Once an alarm is acknowledged it will remain in the alarms list whilst the underlying alarm condition is active. The presence of active but acknowledged alarm conditions is indicated by continuous display of the alarm icon in the status bar.
Figure 17 Text entry 3.14 Long range messages If the Oceansat transceiver is connected to a long range communication system via the long range communications port then long range interrogations may be received. These are requests for information from a distant base station beyond normal AIS operation range.

A ‘blue sign’ switch may optionally be connected to the AIS transceiver during installation. This switch sets the ‘blue sign’ status in transmitted inland AIS position reports to either ‘Set’ or ‘Not set’. If a blue sign switch is not installed the blue sign status is transmitted as ‘not available’.
Installation Installation The Oceansat AIS transceiver has been designed for ease of installation. The transceiver is a ‘one box’ design containing both the transceiver and display. An external junction box is provided to simplify connection of sensor and display data wiring. A typical system and connection diagram is provided in Figure 30.
4.1 What’s in the box? Figure 31 shows the items included with your AIS transceiver purchase. The following section gives a brief overview of each item. Please ensure all items are present and if any of the items are missing please contact your dealer.
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 30cm (1ft) from a compass or any magnetic device.
● An AC power port should be available near to the pilot plug. A pilot plug is located on the front panel of the AIS transceiver and can also be relocated using the junction box. Please refer to section 4.4.2 for guidance.
● The transceiver is supplied with four self tapping screws for attachment of the junction box to a suitable surface. Please refer to Figure 36 for guidance. ● The junction box must be located within 1m (3.2ft) of the AIS transceiver to allow for the length of the supplied data interface cable.
GPS antenna is required for this receiver in addition to any GPS equipment already installed on board. For mounting of the GPS antenna supplied with your AIS transceiver you will require a one inch 14 TPI pole mount. Contact your dealer to source a mount suitable for the installation location.
Crossing of cables should be done at right angles and sharp bends in the antenna cables should be avoided. ● Connect the VHF antenna cable to the VHF connector on the AIS transceiver as shown in Figure 40. VHF antenna...
4.4.2 Data connections The Oceansat transceiver is supplied with a 1m (3.2ft) 50 way data cable for interconnection of the transceiver and junction box. Connect the junction box to the transceiver using the data cable as indicated in Figure 41.

Installation An example of connection to external display equipment is provided in Figure 43, and connections to other equipment and sensors follow the same scheme. To determine the ‘A’ and ‘B’ signal lines on external equipment use a digital volt meter to measure the signal line voltage referenced to ground. If the voltmeter shows a negative voltage the ‘A’...
Installation Along with data port connections the junction box also provides connections to the AIS transceiver alarm relay contacts. The common and normally open alarm contacts are duplicates of the alarm relay connections available at the power connector (see Table 5) whilst the normally closed contact is only provided at the junction box.
4.4.6 PC data connection A 9 way D-type connector is provided on the rear panel of the Oceansat transceiver. This interface allows direct connection to a PC RS232 interface and can be used for installation, diagnostics or external display connection. The default configuration for this interface allows connection of an ECDIS or charting system and duplicates the ‘External display’...
Once all connections have been made the transceiver can be powered and configured for operation. During configuration information about the vessel on which the transceiver is installed is entered into the transceiver. It is important this information is entered accurately as it will be broadcast to other AIS equipped vessels and shore stations.
'External’ option as appropriate. Dimensions for both the internal and external GNSS antennas must be entered if an external GNSS is connected to the AIS transceiver. The antenna dimensions should be entered in metres according to the diagram provided in Figure 47.

3. Check that the status icon display shows ‘OK’ and that the ‘TX’ icon flashes periodically. 4. If the vessel is in an area where other AIS equipped vessels are present press the ‘Screen’ key until the ‘Target list' screen is displayed. Check that data from other AIS equipped vessels is displayed.

Other Inland AIS settings When operating in Inland mode it is possible to connect a ‘blue sign’ switch to the AIS transceiver and also to manually configure the AIS position reporting rate. The connection of the blue sign switch is described in section 4.9.5.
