1 Notices When reading this manual please pay particular attention to warnings marked with the warning triangle. These are important messages for safety, installation and usage of the product. Safety warnings Warning: This equipment must be installed in accordance with the instructions provided in this manual. Warning: Only use this AIS/VHF antenna splitter in conjunction with an approved AIS Class B transceiver or receiver purchased from a reputable supplier.
frequency electromagnetic energy you must make sure that the antenna is mounted at least 1.5 m away from the NSPL-400 and is connected to the NSPL-400 before power is applied. The system has a Maximum Permissible Exposure (MPE) radius of 1.5 m. This has been determined assuming the maximum power of the AIS transceiver and using antennas with a maximum gain of 3 dBi. The antenna should be mounted 3.5 m above the deck in order to meet RF exposure requirements.
2 About your AIS/VHF antenna splitter About AIS • • • • • 6| The marine Automatic Identification System (AIS) is a location and vessel information reporting system. It allows vessels equipped with AIS to automatically and dynamically share and regularly update their position, speed, course and other information such as vessel identity with similarly equipped vessels.
Fig. 1 What’s in the box Warning: This AIS/VHF antenna splitter must not be used with Class A transceivers, Aids to Navigation transceivers or AIS base stations. What’s in the box? Figure 1 shows the items included with your NSPL-400 purchase. The following sections give a brief overview of each item. Please ensure all items are present and if any of the items are not present contact your dealer.
• • end (for connection to the NSPL-400) and a PL259 connection at the opposite end (for connection to the AIS transceiver). NSPL-400 AIS/VHF antenna splitter unit Figure 2 shows an overview of the NSPL-400 unit. The NSPL-400 has a number of indicators which provide information to the user about the status of the NSPL-400. Please refer to section 4 for more details of the indicator functions. The NSPL-400 mounting holes are located as shown in Figure 2.
3 Fig. 4 Installation config. Installation Preparing for installation Figure 3 shows a typical installation configuration for the NSPL-400. Please take the time to familiarise yourself with the system elements and their connections prior to attempting installation.
AIS transceiver If you have an existing AIS transceiver connected directly to a VHF antenna, you can disconnect the AIS transceiver from the VHF antenna and connect them both to the relevant connectors on the NSPL-400. It is necessary to connect the VHF antenna, VHF radio and AIS transceiver for the antenna splitter to function correctly. FM radio The NSPL-400 also provides connections for the antenna of an FM broadcast radio receiver. Connection of an FM radio is optional.
• • • 135 mm 52 mm 98 mm Fig. 5 Dimensions The NSPL-400 is fully waterproof to ingress protection rating IPx7, however it is recommended that the NSPL-400 is not subjected to extended periods of exposure to spray or submersion. It is acceptable to mount the NSPL-400 either vertically or horizontally. The VHF antenna splitter must be installed in a ‘below decks’ environment.
Figure 5 NSPL-400 mounting Fig. 6 Location - VHF Step 2 - Connecting the VHF antenna Route the cable from the VHF antenna to the NSPL-400 and connect to the VHF antenna connector on the NSPL-400 as shown in Figure 6. A standard marine band VHF antenna or AIS antenna should be used with the NSPL-400. The connector type on the NSPL-400 is SO239. Your chosen VHF antenna requires a PL259 connector to mate with this.
Fig. 7 Location - VHF radio Step 3 - Connecting the VHF radio Using the VHF radio accessory cable provided with this product, route the cable from the VHF radio to the NSPL-400 and connect to the VHF radio connector on the NSPL-400 as shown in Figure 7. If the cable supplied is not long enough please contact your dealer for details of suitable extension cables. A standard marine band VHF voice radio should be used with the NSPL-400. The antenna splitter is DSC compatible.
Step 4 - Connecting the AIS transceiver Using the AIS transceiver accessory cable provided with this product, route the cable from the AIS transceiver to the NSPL-400 and connect to the AIS transceiver connector on the NSPL-400 as shown in Figure 8. If the cable supplied is not long enough please contact your dealer for details of suitable extension cables.
Fig. 9 Power and FM Step 5 - Connecting the power supply and optional FM output The NSPL-400 requires a 12 V or 24 V power supply typically provided by the vessel’s battery. It is recommended that crimped and soldered lugs are used to connect the NSPL-400 to the power source. It is recommended that the power supply is connected via a suitable circuit breaker and/or 1A fuse block. 1. Connect the red wire to the power supply positive terminal. 2. Connect the black wire to the supply negative terminal. 3.
4 Operation Operation of the NSPL-400 is automatic and requires no user intervention. During operation the antenna splitter will share signals received at your VHF antenna with both the AIS transceiver and the VHF radio. When either the AIS transceiver or VHF radio transmits, the NSPL-400 will automatically sense the transmission and route the signal to the Fig. 10 Indicator lights antenna.
5 Troubleshooting Issue Possible cause and remedy Power indicator not illuminated Check power supply connections and fuse or circuit breaker Check polarity of power supply connections Check power supply voltage ‘VHF’ indicator does not illuminate when VHF Radiotelephone is transmitting Check the antenna output of the VHF Radiotelephone is connected to the antenna splitter input labelled ‘VHF’ ‘AIS’ indicator does not illuminate when AIS transceiver is transmitting Check the antenna output of the AIS
