AIT2000 Installation & Operation Manual
VERSION 1.01
5.2 Installing the external GPS antenna

For mounting of the optional external GPS antenna you will require a 1” x 14 TPI thread pole, deck base or
rail mount

You should ensure the GPS antenna has a good clear view of the entire sky.

It is not recommended that the GPS antenna is mounted up a mast
where the motion of the vessel will cause the antenna to swing and
potentially reduce the accuracy of the GPS position.

Do not mount your antenna in the direct path of a radar transmitter.

Feed the ten metre long cable attached to the GPS antenna cable
through the pole and screw the antenna onto the pole mount as
shown in Figure 4.

Route the cable to your AIS transponder unit, adding any necessary
extension cables.

Connect the cable from the GPS antenna to the GPS connector on the
AIS transponder
5.3 Connecting to the VHF antenna
Route the cable from the VHF antenna or splitter to the AIS transponder and connect to the VHF connector on the
AIS transponder.

A standard marine band VHF antenna or AIS antenna should be used with the AIS transponder. The con-
nector type on the AIS transponder is a BNC. Your chosen VHF antenna requires a BNC male connector to
mate with this. If your VHF antenna does not use this type of connector please contact your dealer for
details of available adaptors.

If you are using an antenna splitter, connect the AIS connection on the splitter to the VHF (BNC) connect-
or on the AIT2000.

NOTE – if you intend to use a splitter, it is important that the splitter is designed for use with a Class B
Transponder. Some lower cost splitters are only designed for use with AIS receivers and will not work
properly with the AIT2000.
5.4 Connecting the Power/Data cable

The integral 1m Power/Data cable allows connection of DC power, NMEA data (two inputs and two out-
puts) and the remote Silent Switch. The cable is terminated inside the unit and the other end of the cable
has twelve colour coded bare wires ready for connection.

Table 1 on the following page lists the function of each colour coded wire for reference.
