1. GENERAL
1.1 Exposure to RF Electromagnetic Energy
This product complies with EN62311:2008 (EU) and RSS-102 (Canada).
This product has been evaluated for compliance with the FCC RF exposure limits given in
CFR 47 part 1.307(b) at a distance greater than 25cms from the antenna.
1.2 Warnings
This product is designed to assist navigation and should not be used in the place of ap-
propriate navigational judgment. AIS should be used as a complement to navigation and
should not be used to replace installed equipment such as RADAR or ECDIS.
!AIS devices can only monitor other AIS equipped vessels. It is the respon-
sibility of the vessels crew and skipper to always be aware of surrounding
vessels that may not be fitted with AIS equipment.
!The ATB1 must always be used in conjunction with the supplied GPS anten-
na. Use of an alternative GPS antenna may impair the functionality of the
system.
!This product contains no user-serviceable parts. All maintenance work
should be carried out by trained persons authorized by Ocean Signal.
!Do not install in a flammable atmosphere (engine room, near to fuel tanks)
or in a location subject to excessive solar heat (direct sunlight, beneath a
windshield).
!The ATB1 is a maritime radio transmitter and is subject to radio licensing
laws. Contact the relevant authority in your country for local license re-
quirements.
!False information transmitted can result in risk to other vessels as well as
your own. It is the user’s responsibility to ensure that vessel sensors are
configured and calibrated correctly and that all AIS information transmit-
ted is accurate and up to date. It is a criminal offence in some countries to
transmit falsified data.
!USA Users only: It is a violation of the rules of the FCC to input an MMSI that
has not been properly assigned to the end user, or to otherwise input any
inaccurate data in this device. The entry of static data into this device shall
be performed by the vendor of the device or by an appropriately qualified
person in the business of installing marine communications equipment on
board vessels. Instructions on how to accurately enter and confirm static
data in the device can be found in Section 3 of this user manual.

1.3 ATB1 Overview
The Automatic Identification System (AIS) was designed as an aid to collision-avoidance in
the marine industry and is a significant development in navigational safety. It is now widely
used at sea to provide vessels with a live accurate picture of marine traffic in the surround-
ing area.
The fully compliant ATB1 is a Class B type AIS Transponder from Ocean Signal. Your vessel
information such as position, speed, and course is ascertained automatically and contin-
uously using an internal multi-GNSS receiver and transmitted to all other AIS equipped
vessels to maximum of every two seconds.
Other vessel information such as vessel name, call sign, type and dimensions as well as
the MMSI are also transmitted. This information can be uploaded to the ATB1 easily by sev-
eral methods described in Section 3 of this guide. Once this information has been upload-
ed, it remains stored in the unit’s non-volatile memory even if powered down.
The ATB1 also receives and interprets AIS messages from other AIS equipped vessels
within range, which can then be relayed effortlessly to other navigation devices such as
chart plotters, laptops or mobiles using the ATB1’s NMEA0183, NMEA2000, USB or Wi-Fi
outputs.
A multi-colour LED indicator light on the ATB1 signals the on-going operational status of
the unit. This additional safety feature provides you the confidence of knowing that the
ATB1 has continuous AIS transmission and optimal performance.

2. INSTALLATION
2.1 Mounting
2.1.1 Transceiver mounting
Determine the mounting location for the ATB1 ensuring that there are suitable access
routes for all the required cables and attach securely to a flat surface using the four fixing
screws provided. The unit should be easily accessible to allow for disconnection from the
power source. The power/data cable plug is the disconnect device, unplugging this will
isolate the ATB1 from both poles of the power source. It is also recommended that the unit
can be accessed later to view the indicator LED and operate the Mode button.

2.1.2 GPS (GNNS) Antenna Mounting
The GPS Antenna should be installed with a clear and unobstructed view of the sky, it
should NOT be positioned or mounted on a mast that can cause the antenna to swing and
potentially reduce the accuracy of the GPS position and it should NOT be positioned in the
direct path of a radar transmitter.
The GPS antenna can be mounted either on a flat horizontal surface or on a suitable pole
mount (not supplied).
• If you intend to surface mount the antenna, ensure you have access to the
underside of the mounting surface.
• If you intend to pole-mount the antenna, the mount requires a 1 inch 14 TPI
thread.
!If the cable is passed through the center of a third party mount ensure the
thread length does not exceed 2cm (0.78”) to prevent damage to the cable
!DO NOT cut the GPS Antenna cable. Neatly coil and tie any excess cable
After fixing the GPS antenna to an appropriate location, route the 10m cable to your AIS
transceiver unit, adding extension cable as necessary. Connect the cable to the GPS con-
nector on the ATB1.

2.2 Connections
!To avoid damage to the cables, ensure at least 50mm (2.0 inches) is avail-
able below the Transceiver to allow the cables to turn.

2.2.1 RF Connectors
The VHF antenna should be connected to the SO239 socket.
If the vessel is equipped with a single VHF antenna that is required to be shared between
the ATB1 and a VHF Radio Transceiver it is necessary to use an active antenna splitter.
Attempting to connect two transmitting devices to a single antenna without a splitter will
cause severe damage to either or both devices. Install a third party splitter in accordance
with the instructions provided with that unit, connecting the ATB1 “ANT” connector to the
AIS Input connector on the splitter.
A typical active splitter installation connection is shown in the NMEA2000 example on page
6 of this manual.
!When a splitter is installed and the VHF Radio is transmitting, the ATB1
is unable to make use of the SOTDMA system and reporting rates may be
longer than those specified for normal operation. For optimum operation a
dedicated VHF antenna is recommended.
The GPS antenna should be connected to the TNC connector.
2.2.2 Power and data connectors
The power and data connections are on the 10-core flying lead supplied.
Connect the power cables to the vessels supply via a suitable fast acting fuse.
If you need to extend the length of the power cable, ensure you observe the following:
• The power cable for each unit in your system should be run as a separate,
single length of 2-wire cable from the unit to the vessel’s battery or distribu-
tion panel.
• For power cable extensions, it is recommended that a minimum wire gauge
of 16 AWG (1.31 mm2). For cable runs longer than 15 meters, you may need
to consider a thicker wire gauge (e.g. 14 AWG (2.08 mm2), or 12 AWG (3.31
mm2)).
