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 RF PWA (205M0597-00), the CPU PWA
(205M0596-00), and the PS PWA (205M0598-00).

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.

1.4.4. Long Range Equipment Interface

The range of operation of standard AIS is limited to the range of VHF transmissions
which is around 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.

Feb. 01/05

Initial Issue165M0601-00

Page 1–15

Aviation Recorders

Marine Systems

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.

The alphanumeric keypad is used to enter both numbers and letters. When alphanu-

meric text entry is expected, the nonnumerical options are presented before the nu­meric value of the key. For example, the number “2” key provides for entry of “A”,
“B”, and “C”. When the cursor is positioned in a display field location that expects an
alphanumeric character, the first press of the “2” key will result in the display of an
“A”. Another press (in less than one second) will cause a “B” to be displayed. The
next press shows a “C”, while the forth press shows a “2”.

F Transponder

F VHF Antenna

F GPS Antenna

F Data Interface

F Powerup and Configuration

Each operation will be discussed in detail below. In regards to 3rd part components
such as VHF and GPS antennas and Gyro interfaces, it is suggested that the
installation procedures suggested by the manufacturer be followed in lieu of these
procedures.

3.1.1. Transponder

The L-3 ProTec is a single box design which is easily installed into any existing
bridge layout. The compact design requires minimal clearance (refer to Section 4
Figure 4–1 and Figure 4–2) and can be mounted in a trunion bracket or mounted
flush using the available flush–mount bracket.

F Mount the transponder in a position which provides easy access to the key-

board and display.

F If using the trunion bracket, the mount itself may be used to mark the screw

holes on the mounting surface. When locating the transponder, consider that

the IMO mandates that the AIS keyboard and display be easily accessed from

a navigable position on the bridge.

F If used, Mount the transponder in the trunion utilizing the trunion knobs pro-

vided, otherwise mount transponder in flush mount bracket.

F Locate and mount the terminal block or junction box in a position near the

transponder. The IEC cable provided with the unit is 100 inches (2.54 m) long.

Locate the terminal block in a fashion which allows for easy access to the termi-

nals for making the connections to required input/output feeds.

Aviation Recorders

Marine Systems

F When connecting the power cable, the “Red“ lead goes to positive and “Black“

to negative. Ensure proper ground wire attachment to ships structure. The oth-

er two leads can be used to connect to an external alarm system. This alarm

system can provide an audio and/or visual alarm in the event of an internal sys-

3.1.2. Connecting the IEC Data Interface Cable

The AIS Transponder receives data from the ship’s sensors through a data interface
cable which is connected to the back of the transponder through a data port. IMO
regulations require that the ship heading, speed–over–ground (SOG), course–over–
ground (COG), rate–of–turn (ROT) and position be transmitted from the AIS. In or­der to meet these requirements, the L-3 ProTec provides six (6) data channels to al­low the AIS to be connected to the ships Gyrocompass and DGPS system in accor­dance with NMEA 0183.

The L3 AIS is shipped with one IEC interface cable P/N 024M0599-00. All IEC/Pilot
communications with the AIS is referenced with the L-3 ProTec considered the
“MASTER” in that transmit data is OUTPUT from the L-3 ProTec, and receive data is
INPUT to the L-3 ProTec. All channels are isolated with individual shielded twisted
pair cables. For more inforomation, refer to Figure 4–3. The IEC connector (J4) is
located on the back of the L-3 ProTec. (Refer to IEC 61993–2 annex D. and NMEA

0183) IEC channels 1, 2, and 3 are RECEIVE ONLY sensor inputs. Differential data
(RS422) is received on each of these channels and internally converted to TTL for
input to a standard UART. Channels 4, 5, and 8 are all RS422 interfaces. IEC chan­nels 4 and 5 are TRANSMIT/RECEIVE channels for AIS data. IEC channel 8 is the
AIS long range port.

3.1.2.1 Data Channels

Data enters the Transponder through six (6) available data channels. Three data
channels are low speed unidirectional (4800 baud) channels suitable for data input
to the transponder. The other three data channels are high speed bidirectional
channels (38400 baud) which support both input and output to/from the transponder.

The channels are described below by channel number and type. Suggested uses of
each channel are provided but it is not required that a user define the channels in
this fashion. The internal software in the transponder is able to distinguish the type
of data feeding from each channel provided all data streams subscribe to the IEC
61162 format (NMEA 0183).

Table 3–1. Data Channels

Channel BAUD Type Suggested Use

1 4800 Receive dGPS (COG, SOG, LAT, LON)
2 4800 Receive Rate of Turn
3 4800 Receive Heading (Gyro)
4 38400 Transmit / Receive PC Application
5 38400 Transmit / Receive ARPA/ECDIS
8 38400 Transmit / Receive Long Range Tracking (Dedicated)

The IEC I/O electrical characteristics are as follows:

The “A”, “B” and “C” leads are as defined in IEC 61162–1, 61162–2 and V.11.
“A” and “B” are both signal leads with “C” being the effective return for both the “A”

and “B” leads.
“A” and “B” operate differentially to each other.
High–level output voltage is 4V minimum from the “A” lead to the “C” lead and from

the “B” lead to the “C” lead. Low–level output voltage is 0.4V maximum.
Recommended maximum output current capability is 110mA.
Input is differential from “A” to “B”. Effective input resistance is 4.9k ohm across “A”

and “B” and 96k from “A” or “B” to “C”.
Differential input voltage threshold is 250mV maximum.
Inputs will meet the requirement of withstanding +/–15V between any two leads, “A”,

“B” or “C”.

3.1.2.2 Data Cable

Each transponder will come shipped with an 100 inches long IEC data cable (P/N
024M0599-00) terminated at one end by a J4 connector. (Refer to NO TAG,
Figure 4–3 and Figure 3–2.) The IEC data cable is shielded and contains three
smaller diameter cables, each of which is also shielded. Each of these smaller
cables contains three shielded twisted pairs (STP) each and each STP includes a
drain wire. A low speed unidirectional (input only) data channel (4800 Kbs) is carried
through one STP, and a high speed bidirectional (input/output) data channel (38400
Kbs) will require two pairs.

3.1.2.3 Terminal Block

A terminal block is the preferred installation method for completing the data interface
(NMEA) because data output from a ship sensor ( dGPS, ROT, Gyro) may not sub­scribe to a standard pinout definition. As such, each installation may require that
the installer identify and cross reference the sensor pinouts with the IEC pinouts,
which is a well defined standard pinout description. The terminal block allows for
greater flexibility in completing the connection to the ship’s sensors.

Feb. 01/05

Initial Issue165M0601-00

Page 3–7

Aviation Recorders

Marine Systems

A junction box may be made available which terminates the data cable on the termi­nal block and provides serial connectors to allow for easy connection to ship sen­sors. However, the installer will need to confirm the pinout definitions for the sensor
outputs before completing the connection correctly.

3.1.3. Installing the VHF Antenna

Installation of a VHF antenna is as important to reliable communications as the
transceiver itself. It is recommended that a high quality antenna be purchased from
an established source and that all manufactures instructions be followed with partic­ular attention to cable routing and connector installation. Some important consider­ations in antenna installation are:

F In general, antennas should be located as high as practical on the vessel

and separated as much as possible from each other.

F The VHF antenna should be placed in an elevated position with a mini-

mum of 2 meters clearance from any construction that is made with con­ductive material. In addition, it should not be installed close to any large
vertical obstruction, and the VHF antenna should have a 360° line of sight
to the horizon.

F It is preferable that the VHF antenna is installed at least 3 meters away

from high power energy sources such as radar and other transmitting ra­dio antennas, and out of the transmitting beam.

Marine Systems

F There should not be more than one antenna on the same level. The AIS

VHF antenna should be mounted directly above or below the ship’s prima­ry VHF radiotelephone antenna, with no separation and with a minimum of
2 meters vertical separation. If the VHF antenna is located on the same
level as other antennas, the distance between them should be at least 10
meters.

To install the VHF antenna, perform the following:

(Refer to Figure 3–5 and Figure 3–6.)
(1) Position the antenna mounting bracket on a rigid and structurally sound sur-

face.

(2) Install the antenna on the antenna mount.

NOTE

: Use only high quality RG213/RG214 coaxial cable and keep

cable length as short as possible to reduce signal attenua­tion.

(3) Run the coaxial cable from the antenna to the transponder location.
(4) Trim cable to length leaving a few inches slack at the transponder.

Feb. 01/05

(5) Attach the connectors to the end of the coaxial cable.
(6) Connect the cables to the transponder. Soldering the connection is

recommended.

3.1.4. Installing the GPS Antenna

The correct installation of a GPS antenna is crucial to the operation of the trans­ponder because the internal transmission synchronization relies on the accuracy of
the time signal obtained from the GPS. It is recommended that a high quality GPS
antenna be purchased from an established source and that all manufactures instruc­tions be followed with particular attention to cable routing and connector installation.
Some important considerations in GPS antenna installation are:

F GPS antennas should be located to provide a clear, unobstructed view of

the sky.

F GPS signals can be affected by RADAR and SATCOM transmissions. As

such, GPS antennas should be positioned below and at least 5 meters
away from RADAR and SATCOM antennas and outside of the beam path.

F GPS signals can also be affected negatively by VHF and HF transmis-

sions, and the GPS antenna should be positioned at least 3 meters from
these types of antennas.

F The GPS antennas can be flat mounted onto any surface but it is recom-

mended that it be elevated from the deck surface (20–30 cm.) to prevent
ice or spray from negatively impacting the signal reception.

F Recently, it has been identified that certain makes/models of TV antennas

can drastically interfere with GPS reception. As such, the installer should
place the GPS antenna as far away from any shipboard TV antennas as
possible and confirm that any antennas used on board are not ones which
have been exhibited GPS interference problems.

To install the GPS antenna, perform the following:

(Refer to Figure 3–5 and Figure 3–6.)
(1) Position the antenna mounting bracket and/or antenna mast on a rigid and

structurally sound surface.

(2) Install the antenna on the antenna mount.

NOTE: Use only high quality RG213/RG214 coaxial cable and keep cable

length as short as possible to reduce signal attenuation.

(3) Run the coaxial cable from the antenna to the transponder location through an

existing throughhull.
(4) Trim cable to length leaving a few inches slack at the transponder.
(5) Attach the connectors to the end of the coaxial cable.
(6) Connect the cable to the transponder. Soldering the connection is

recommended.
