All active alarms will be displayed along with an exclamation mark (!) next to the alarm number. To clear the alarm, select that alarm and press CLEAR, the exclamation mark will disappear. When all alarm conditions have no exclamation mark (!) the BIIT relay will deactivate. 3.26 Show Status Menu These screens relate to the performance of the Transponder. The first screen shows the Purpose (SOLAS ships must show Class A) and the MMSI number. Refer to sections 4.4 and 4.3 for further details.
4.18 Alarm Signals Menu (Default = On) In this menu, the status of different alarm signals can be viewed and enabled or disabled. The alarm signals will give validity information to the operator in case a fault occurs. Therefore it is recommended to keep all the alarm signals set to ‘On’ which is the default setting. The transponder contains a Built-In-Integrity-Test (BIIT) that continuously monitors the standard functions of the equipment.

4.21 DGNSS Set-up Menu UAIS can transfer differential data corrections via the AIS channels (message 17). Data received via the RTCM input port may be sent to 2 reference stations whose geographical co-ordinates are known and which have been manually set up. If the reference station is transmitting RTCM message 3, it is showing its own coordinates that UAIS can store. No more than 4 reference stations can be stored at any one time. 4.
After successful completion of the self-test and communication between the VDU and the transponder has been established the following screen will appear. The welcome screen giving the GNSS type (GPS or GLONASS), software version, and software build date then appears, which confirms that the VDU is ready for operation. Press to enter the Main Menu. SELECT - Enter set-up from the menu.
Press to stop data transmission. At this point a system password has to be entered. If no previous password has been entered, pressing OK will by-pass this request. A password should be entered to prevent accidental or malicious changing of stored data. THIS PASSWORD SHOULD BE RECORDED IN A SECURE PLACE. WARNING: It is not possible to access Main Setup without entering the correct password. Only authorised service personnel can restore access. 4.
4.3 General Set-up Menu The General set-up menu allows the following parameters to be set up: 4.4 MMSI The Maritime Mobile Service Identity (MMSI) number must be entered. 4.5 Purpose Select purpose of the UAIS station.
4.6 IMO Number The assigned ship’s IMO number has to be entered. 4.7 RAIM Present (Automatically selected) The station will automatically check for RAIM presence in working mode – by $-GBS sentences on Sens1, Sens2 or Sens3 inputs. The operator can manually override the automatic selection by highlighting the RAIM line and selecting Change. In normal circumstances this function is not used. 4.8 Setup System Password For safety reasons some data is protected by a system password (maximum 8 characters).
4.9 Addressed Message Filter (Automatically selected) Enables filtering of addressed UAIS messages. When addressed message filter is “on” the station does not display messages addressed to other AIS stations, when “off” all received addressed messages will be displayed. 4.10 Media Analyser Mode Designed to work with the proprietary Transas media analyser software. This option should be set to “No”. 4.11 Max.
4.13 Enable Deleting Regions Recommendation: leave at the default = No Press 4.14 to exit General set-up and return to Main set-up menu. Extra Setup Menu From the Main set-up menu, select Extra set-up that has the following options :4.15 Intern. GNSS Position The internal GNSS is used for TDMA synchronisation. However, if the navigational information is not supplied from the main external GNSS, the internal GNSS unit may be utilised to supply the navigational information.
4.16 Dist.Int.GNSS-Bow Dist.int.GNSS-Stern Dist.int.GNSS-Port Dist.int.GNSS-Starboard If the internal GNSS is enabled to supply navigational information it is necessary to set up the relative position of the GNSS antenna as illustrated below. This should be carried out during commissioning. The distances marked as A, B, C and D on the illustration below are the distances from the internal TDMA synchronisation GNSS antenna to the ship’s bow, stern, port side and starboard.

Note that after power up approximately 2 minutes elapses before the UTC is available (log entry 'UTC clock found'). During this time period, and for about 30 seconds after, any entries to the log file will have a null timestamp (00-00-00 24:60:60). The elapsed time from power up will be valid. Approximately 2.5 minutes after power up log entries will be both timestamped and show an elapsed time since power on.
3.34 Log File (Security) On selecting this display there will be a delay whilst the security log records are filtered from the complete log file. 3.35 Enter Setup Menu For safety reasons this menu is protected by a system password which is normally entered during commissioning. (See section 4.8 Setup System Password on page 36). 3.36 Display Brightness Menu To adjust the touch-screen LCD to suit ambient light conditions, select Display Brightness from the Main menu.
4 Commissioning WARNING: ENSURE THAT THE UAIS HAS BEEN CORRECTLY INSTALLED IN ACCORDANCE WITH IMO GUIDELINES AND INSTALLATION MANUAL BEFORE SWITCHING ON Please read all the warning notices at the front of this manual before turning on the Transponder. Before switching on the power supply for the first time, conduct a thorough visual inspection of all cabling and connections to determine that they are terminated correctly and that the 24VDC power supply has been connected appropriately.
At power-up the system conducts a series of self-tests and the results are displayed on-screen as follows:- 32 89-042 Issue 5
