Preparing For Installation; Installation Procedures - Raymarine AIS950 Installation Instructions Manual

4.2 Preparing for installation

In addition to the items provided with the AIS950 transceiver the following items will be required to complete
the installation:
4.2.1 VHF Antenna
Connection of a suitable VHF antenna will be required for the AIS transceiver to operate. A standard marine
band VHF antenna such as that used with VHF voice radios is sufficient. The antenna cable should be
terminated with a PL-259 (or UHF) connector. Please take note of the warnings listed at the start of this manual
regarding the installation and use of antennas.
4.2.2 Antenna cables
The supplied GPS antenna is provided with 10 metres (32.8ft) of cable. If this is not sufficient to reach between
the desired GPS antenna location and the AIS transceiver you will require an extension cable. Please contact
your dealer for details. For reference the GPS antenna connector type on the AIS transceiver is a TNC
receptacle and is intended to mate with a TNC jack connector on the GPS antenna cable.
4.2.3 GPS antenna mount
A mounting bracket is required for the supplied GPS antenna. The antenna has a standard one inch 14 TPI
pole mount thread. You should source and install a compatible antenna bracket suitable for the installation
location.
4.2.4 Data interface cables
Suitable screened, multi core cable will be required to connect the ships sensor (DGPS, Gyro etc.) data ports
to the AIS junction box.

4.3 Installation procedures

Before beginning installation of your AIS transceiver, please ensure you have the necessary additional items
as detailed in section 4.2. It is strongly recommended that you read all of the instructions in this manual prior
to installation.
If after reading this manual you are unsure about any aspect of the installation process please contact your
dealer for advice. The following sections explain the installation process step by step for each of the main
system elements.
4.3.1 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.
● There should be adequate space around the AIS transceiver for routing of cables. See Figure 34 for
details of the AIS transceiver dimensions.
● The ambient temperature around the AIS transceiver should be maintained between -15°C and +55°
(5°F to 131°F). Ensure adequate ventilation is present when panel mounting the transceiver.
● The AIS transceiver should not be located in a flammable or hazardous atmosphere such as in an
engine room or near to fuel tanks.
● The AIS transceiver must be installed in a 'below decks' environment protected from the weather.
● The transceiver is supplied with four self tapping screws for attachment of the AIS transceiver to a
suitable surface using the trunnion bracket. Please refer to Figure 35 for guidance.
● The transceiver is supplied with panel mount clamps for flush mounting through an instrument panel.
Please refer to Figure 36 for guidance. Access behind the panel is required when using this mounting
option.
● The AIS transceiver should be mounted in a location where the display is visible to the user at the
position from which the vessel is normally operated.
