GENERAL

This product and related documentation must be reviewed for familiarization with safety
markings and instructions before operation.

This board was constructed in an ESD (electroćstatic discharge) protected environment. This is
because most of the semiconductor devices used in this board are susceptible to damage by static
discharge.

Depending on the magnitude of the charge, device substrates can be punctured or destroyed by
contact or mere proximity of a static charge. The results can cause degradation of device perforĆ
mance, early failure, or immediate destruction.

These charges are generated in numerous ways such as simple contact, separation of materials,
and normal motions of persons working with static sensitive devices.

When handling or servicing equipment containing static sensitive devices, adequate precautions
must be taken to prevent device damage or destruction.

Only those who are thoroughly familiar with industry accepted techniques for handling static senĆ
sitive devices should attempt to service circuitry with these devices.

In all instances, measures must be taken to prevent static charge buildćup on work surfaces and
persons handling the devices.

1.1. General

The L-3 ProTec is an Automatic Identification System transponder which is fully com­pliant to the technical specifications defined by the IMO and outlined in ITU.R.M
1371-1. The transponder employs the latest radio frequency and SOTDMA and DSC
controller technology to provide a high performance, automated, and reliable identifi­cation system for commercial mariners. The Transponder is a fully automated sys­tem which ties into ship’s navigational instruments to provide automatic transmission
of ships identity, status, and maneuvering intentions via standard marine VHF com­munication techniques. Sequencing of transmission between all vessels within VHF
range is provided through SOTDMA controlling software to handle high traffic vol­ume situations.

The Transponder is a fully automated system. This means that once it is installed
and turned on, no maintenance is required to keep it operational. The only time the
user needs to perform any function on the transponder is to change the ship’s Ves­sel/Voyage data as required.

ProTec AIS Introduction

1.1.1. System Overview

The L-3 ProTec is an Automatic Identification System fully compliant with the IMO
specifications defined in IMO MSC.74(69) Annex 3, IEC 61993-2, and ITU.R
M.1371-1. This AIS transponder has been developed using technology applied in
the design of our VHF DSC Class A radio, a design which has been field tested for
over a decade with over 10000 units operational in the field. With the addition of the
SOTDMA controllers, the L-3 ProTec provides a cost-effective AIS solution which will
meet the needs of any vessel required to carry AIS. The compact, single-box design
allows the L-3 ProTec to be easily incorporated into any bridge layout thus simplify­ing installation and cabling requirements.

The L-3 ProTec has been designed as maintenance-free unit which makes extensive
use of surface mount technology (SMT). The repair of printed wiring assemblies
(PWAs) containing SMT components requires specialized factory equipment, train­ing, and techniques, therefore, such PWAs are not field-repairable.

As a result, maintenance philosophy for the L-3 ProTec is replacement of failed as­semblies. In the case of the L-3 ProTec, the replaceable assemblies are the Face­plate Assembly (192M0093-00), the Main PWA (205M0023-12), the Channel 70
PWA (205M0003-01), the IEC PWA (205M0274-11), and the Controller PWA
(205M0307-01).

1.3. AIS Description

1.3.1. Compact Design

The completely self-contained L-3 ProTec is the most compact AIS unit available on
the market today with outside dimensions of 6.5” W (16.5 cm.) x 3.4” H (8.6 cm.) x

7.4” D (18.8 cm.). It is easily mounted on any surface using either a trunion bracket
or flush-mount bracket. The data port on the faceplate provides for easy connection
to any external display in either mounting configuration.

1.3.2. Integral Minimum Keyboard Display (MKD)

In line with the compact design, the L-3 ProTec is a single-box design incorporating
an integral MKD which is fully IMO compliant. The interface includes a 2.58” L (6.5
cm.) x 1.16” H (2.9 cm.) (160 x 64 Dots) backlit LCD screen for displaying alphanu­meric text and a multifunction keypad. The closest three vessels within AIS range
will be displayed with each vessel identified by MMSI and ship name and will display
both range and bearing to each vessel.

The interface has been designed to facilitate data entry and retrieval with a minimum
of keystrokes. It also includes a Pilot port designed to allow any user to quickly and
easily attach a portable AIS-compatible display system directly to the AIS transpond­er for display of the AIS data. This display system can consist of any system which
recognizes the NMEA AIS string whether it’s installed on a handheld PC, laptop PC,
or dedicated display.

1.3.3. Integral GPS

The L-3 ProTec includes an internal GPS receiver card. The internal GPS provides
timing data required for synchronization of transmission. By specifications, ship posi­tional information in NMEA format is to be fed to the transponder from the ships ex­ternal electronic position indicating system through the supplied data cable. The in­ternal GPS requires a dedicated GPS antenna to be mounted on the superstructure
and the appropriate connections are supplied on the transponder unit back panel.

1.3.4. Data Interface

Each transponder will be delivered with an IEC-specified NMEA standard data cable
required to interface to ship’s sensors and external display. The description of this
interface cable is given in the Installation Section of this manual. The standard kit
includes an eight (8) ft. (2.9 meters) cable and a terminal block to facilitate the final
linkup to the ship’s navigational instruments.

1.3.6. Operational Modes

The ProTec AIS is designed to operate in each of three modes: Autonomous and
Continuous, Assigned and Polled which are defined below.

1.3.6.1 Autonomous and Continuous

This is the default mode. The ProTec AIS will determine its own schedule for trans­mission of position and identification and will automatically resolve scheduling con­flicts with other stations using the Self Organized Time Division Multiple Access
(SOTDMA) methodology.

1.3.6.2 Assigned

The ProTec will automatically switch to assigned mode when it is commanded by a
competent authority, such as a base or repeater station, to transmit on a specific
transmission schedule. In this mode, the ProTec allocates the defined slots and be­gins transmitting on these slots. It will continue to transmit in these slots with a zero
slot time-out and a zero slot offset, until those slots have been removed from the
transmission schedule. The assigned slots use the SOTDMA access scheme, with
the time-out value set to the assigned slot time-out. The assignment terminates
when the slot time-out reaches zero of any assigned slot, and the ProTec returns to
autonomous and continuous mode.

1.3.6.3 Polled

The ProTec AIS will transmit a response to DSC interrogation messages from a ship
or competent authority and respond back on the same channel without interfering
with either of the other two modes. When an automatic response is required, trans­mitted responses will be made on channel 70 unless the unit is instructed to transmit
on another channel. The ProTec is inhibited from transmitting on the AIS 1 and AIS
2 channels. If and when frequency channels other than channel 70 are used for
DSC transmissions, the receive capability of TDMA operations should not be
impaired more than it would be if all DSC messages were transmitted on channel

70.

1.3.6.4 Initialization

The ProTec AIS will enter into an Initialization mode at Power-Up during which it will
monitor the TDMA channels for one minute. During this initialization period, a dy­namic directory of all users in the system will be created which includes user IDs,
slot assignments, positions, and other transmitted data. After this initialization period
of 1 minute, the ProTec will enter the required operational mode and begin transmis­sion of the AIS data on the required schedule.

1.3.7. DSC Functionality

The Assigned and Polled operational modes are activated through a DSC message
transmitted by the competent authority. In order to provide for this, the ProTec AIS
contains a dedicated DSC receiver that is tuned to channel 70. DSC messages
originating from shore stations of competent authorities will define regional AIS fre­quencies, regions of coverage, required transmission schedule and/or interrogation
request. The ProTec AIS will respond back to such DSC interrogations on the fre­quency specified in a manner such that it does not interfere with the TDMA transmis­sions by interleaving the transmission between TDMA transmissions. The DSC re­sponse will be made after a random delay of 0 - 20 secs provided the signaling
channel is clear and the TDMA transmissions are not interrupted.

1.3.8. AIS Broadcast Parameters

The International Telecommunications Union World Radio Conference in 1997 desig­nated two VHF radio frequencies: 161.975 MHz (AIS1, or channel 87B) and 162.025
MHz (AIS2, or channel 88B) for AIS. In the US, the first channel is owned by Mari­TEL, a public coast station operator, and the second by the federal government. The
USCG signed a Memorandum of Agreement with MariTEL for use of AIS 1, and has
authority from the National Telecommunications and Information Administration to
use both AIS1 and AIS 2 US-wide for AIS operation. The USCG has asked the Fed­eral Communications Commission to authorize any US vessel to operate AIS on
these two channels under its existing ship station license. The FCC released a No­tice authorizing operation of AIS under a ship’s existing station license.

1.4.3. Pilot Input / Output Port

The Pilot input/output port is a part of the AIS Class A stations. If the installation of
the AIS equipment is such that a pilot cannot connect his Personal Pilot Unit (PPU)
with a reasonable length of cable, an extension cable must be installed with a con­nector located on the bridge such that the PPU can be connected on the normal
working position of the port.

The Pilot input/output port defined by IEC 61193-2 for connections of ship’s pilot
equipment shall, if fitted, be connected using the pilot port cable, p/n: 024M0099-03.
The Pilot input/output port meets the requirement of IEC 61162-2 and is terminated
as shown in Table 1–4.

1.4.4. Long Range Equipment Interface

The range of operation of standard AIS is limited to the range of VHF transmissions
which is approximately 30 miles. The Long Range mode is intended to allow the ex­change of ships position information from ship to a competent authority via a satellite
interface such as Inmarsat-C which is already onboard many ships. This port is in­tended to interface with the Long Range equipment.

The Long Range reply can be set in either:

F automatic mode (AUTO)

F manual mode L-3 ProTec (MANUAL)

F manual mode external application (EXT APPL).

The Long Range reply, when in AUTO mode, is made as soon as a request is re­ceived on the Long Range communication port.

The Officer of the Watch must approve the Long Range reply when in MANUAL
mode, by a means of pressing a keyboard button on the L-3 ProTec before the reply
is performed.

The Long Range reply, when in EXT APPL mode, is made by the L-3 ProTec upon
reception of confirmation / acknowledgement from the external application via the
high-speed ports. The external application acknowledges the interrogation by return­ing the LRF sentence (updated with reply information).

1.4.5. Long Range Input Data and Formats

The input data and formats are in the form of two Long Range interrogation sen­tences, LRI and LRF, refer to Table 1–5.

F The LRI -sentence contains the information needed to determine if a reply

needs to be constructed.

F The LRF-sentence identifies the information items that are being re-

quested. Details of each sentence can be found in IEC 61162-1.
