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 (electro–static 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 performance, 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 sensitive devices should attempt to service circuitry with these devices.
In all instances, measures must be taken to prevent static charge build–up 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 RF
Main PWA (205M0023--00), the Channel 70 PWA (205M0003--01), the Computer
PWA (p/n: 205M0272 --00), the Display PWA (205M0051--00), the IEC PWA
(205M0274--00), and the Controller PWA (205M0008--00).

When it has been determined that one or more of these assemblies is faulty, the
faulty assembly(ies) should be removed and returned to the Aviation Recorders factory for repair or replacement. Attempts to repair any of these assemblies will void
the warranty. Extreme care should be used when handling these assemblies.

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 o n 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 of 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. (2.5 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 o ther 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 ID’s,
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.
Automatic Identification System
Rev. 02 Page 1--10
July 29/03
Aviation Recorders
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
A Class A AIS unit broadcasts the following information every 2 to 10 seconds while
underway, and every 3 minutes while at anchor at a power level of 12.5 watts. The
information broadcast includes:
Marine Systems
F MMSI number -- unique referenceable identification.
F Navigation status
F Speed over ground -- 1/10 knot resolution.
F Position accuracy -- differential GPS.
F Longitude -- to 1/10000 minute and Latitude -- to 1/10000 minute.
F Course over ground -- relative to true north to 1/10th degree.
F True Heading -- 0 to 359 degrees derived from heading sensor.
F Time stamp -- The universal time to nearest second that this information
was generated.
In addition, the Class A AIS unit broadcasts the following information every 6

1.3.9. AIS Frequencies
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.

ProTec AIS Operation
2.1. Operation
The L--3 ProTec has been designed to require minimal user interaction during normal operation. The interface consists of an integral alphanumeric display with alphanumeric keypad providing for data entry, retrieval and display.
2.1.1. Minimum Keyboard Display
The L--3 ProTec includes and integral MKD which is fully IMO compliant. It is recomended that the MKD should not act as the primary display due to limitations in
data presentation options. It should be used for configuration of the hardware and
entry of vessel and voyage specific data, which is required infrequently. It may also
serve as a backup display if the external display were to malfunction. L--3 strongly
recommends that the AIS Target Display Software (TDS) be used as the primary AIS
display system and this software is available from the hardware supplier. TDS is a
basic yet powerful graphic display software compatible with Windowst which provides numerous display options for the AIS data. Contact L--3 Communications for
further information and acquisition. The front face of the L--3 ProTec contains the following controls.

2.1.1.1 Power/Dim Control
A single control knob controls both the on/off function and backlighting level for the
LCD. To turn the unit ’On’, rotate the knob clockwise. To turn unit ’Off’ rotate counterclockwise fully. The degree of rotation determines the brightness of the LCD backlight and rotation to the right will dim the backlighting.
2.1.1.2 Liquid Crystal Display
The display is an alphanumeric LCD with backlighting which will display data entry
forms and AIS target data for the nearest three vessels.
2.1.1.3 Key Pad
The keypad contains dedicated function buttons and alphanumeric buttons which
allow for data entry and retrieval.
2.1.1.4 Pilot Port
The Pilot Port is an IEC high speed (38400 kbs) data port which can be used to connect any external display such as an ECS, or other PC--based software package.

Edit operation.
CLR Clear Key
Used to clear data from a data entry field before entering new data .
Pressing once will clear the entire field.
Directional ARROW Keys
Used to navigate between data entry fields on a data entry form and scroll
right/left and up/down in an alphanumeric display field. When in Closest

Vessel (default) screen, the Left or Right Arrow Keys will allow the user to
toggle between the Ship Name display and the MMSI screen. (The MMSI
screen will always be displayed for a vessel if the ship name is not known.
FNC Function Key
Used as the initial key in a key sequence to access the various secondary
functions of the interface.
CAN Cancel Key
Used to cancel any edit made in a data entry field and revert data back to
preexisting data.
MSG Message Key
Used to access the text messaging window, in order to send Safety Text
Messages.
ESC Escape Key
Will bring user up one level on the menu system.
Aviation Recorders
Marine Systems
The blue text above some identify the secondary definitions for each button. These
secondary definitions are activated by pressing of the FNC button in a key sequence.
SETUP Enters the system configuration menu system.
HOME Returns cursor to start position in a data entry field
END Returns cursor to end position in a data entry field
ALL Will clear all contents of a data entry field when preceded by the FNC key.
The alphanumeric keypad is used to enter both numbers and letters. When alphanu-
meric text entry is expected, the nonnumeric 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 a fairly short time) will cause a “B” to be displayed. The next
press shows a “C”, while the forth press shows a “2”.
Repeated key presses will result in cycling through the character options repeatedly.
When the operator stops pressing keys for longer than the preset timeout, the last
value is retained and the cursor moves to the next location in the field. Pressing a
different key forces acceptance of the last character for the field and moves the cursor along.

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 Figure 3--2
and Figure 3--3) and can be mounted in a trunion bracket or mounted flush using the
available flush--mount bracket. Install the transponder is as follows:
(1) Mount the transponder in a position which provides easy access to the key-
board and display. If using the trunion bracket, the mount itself may b e 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.
(2) If used, Mount the transponder in the trunion utilizing the trunion knobs pro-
vided, otherwise mount transponder in flush mount bracket.
(3) Locate and mount the terminalblock or junction box in a position near the
transponder. The IEC cable provided with the unit is 100 inches (2.5 m) long
and the terminal block should be located to take this into account. Locate the
terminal block in a fashion which allows for easy access to the terminals for
making the connections to required input/output feeds.
Aviation Recorders
Marine Systems
(4) Refer to Figure 3--4. Connect the transponder power cable to the power con-
nection on the Transponder and connect to the ships 12--24 Vdc power supply.
The “Red“ lead goes to positive and “Black“ to negative. Ensure proper ground
wire attachment to ships structure.
The other 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 system malfunction, or if the AIS loses power or is turned off.
For steps (5) through (7) refer to Paragraph 3.1.2.
(5) Connect the IEC cable to data port on back of Transponder using J4 connector
provided.
(6) Lead data cables from Gyrocompass data output port and ship’s DGPS data
output port. To terminal block. If an interface adapter must be used to convert
either Gyro output and/or dGPS output to IEC (NMEA 0183) standard, the output from the interfaces should be located as near as possible to the sending
unit (Gyro or dGPS) and the output cables led to the IEC terminal block.
(7) Feed the IEC data cable pigtail to the terminal block.
(8) Do not power up the unit at this time. The transponder should not be powered
up without the VHF antenna connected.
(9) If an external display system is to be connected for display of the AIS target
data, lead the cable from the display unit to the terminal block. (Refer to
Figure 3--5.)

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 b e 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 024--M0088--01. 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. Refer to Figure 3--7. 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)

3.1.2.2 Data Cable
Each transponder will come shipped with an 100 inches long IEC data cable (P/N
024--M0088--01) terminated at one end by a J4 connector. (Refer to Figure 3-- 6,
Figure 3--7 and Figure 3--8.) 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 h igh speed bidirectional (input/output) data channel (38400
kbs) will require two pairs.

3.1.2.3 Terminal Block
Each Transponder will come shipped with a 31 pin 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 installeridentify
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.
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.
To complete the data connection to the ship’s sensors, perform the following:
(1) Connect the data cable to the back o f the transponder unit.
(2) Feed the data cable into the console to the position in which the terminal block
will be placed.
Aviation Recorders
Marine Systems
(3) Locate an ideal position for the terminal block.
F Protected from weather.
F Protected from high heat.
F Protected from accidental contact with conductive material.
F Within 100 inches (2.5 m) of the transponder due to IEC data cable length.
F Grounding of terminal block to ship’s structure.
F Need to feed cables from navigational sensors.
(4) Mount the terminal block to the ships structure with self tapping screws
(5) Ground terminal block to ship’s structure using grounding cable provided.
(6) Connect each wire to the correct terminal block position. Use the table below
which gives the IEC pin ID (and color code) and identifies the correct terminal
block position ID.
NOTE
: The metallic shielding of each of the three shielded cables
containing the twisted pairs must be connected to the terminal block using the shield drain wire connected to the
shield. The shields from Cables 1 and 2 do not have to be
connected. The shield from Cable 3 must be connected to
TB pin ID 30, which is grounded to the ship’s hull.

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.
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.
Marine Systems
To install the VHF antenna, perform the following:
(Refer to Figure 3-- 9 and Figure 3--10.)
(1) Position the antenna mounting bracket on a rigid and structurally sound sur-
face. In general, two bracket types are available, a rail mount and a flat (padeye) mount. Some mounts have a ratchet mechanism which allows them to be
mounted on an inclined surface. Whichever mount is used; ensure the quality
of the mount. L--3 recommends a heavy gage stainless steel mount be used in
the mounting of the antenna.
(2) Install the antenna on the antenna mount.
(3) Run the coaxial cable from the antenna to the transponder location. Use only
high quality RG8X or RG214 coaxial cable and keep cable length as short as
possible to reduce signal attenuation.
(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 cables to the transponder. Soldering the connection is not
required.

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.
Marine Systems
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-- 9 and Figure 3--10.)
(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.
(3) Run the coaxial cable from the antenna to the transponder location through an
existing throughhull. Use only high quality RG59 coaxial cable and keep cable
length as short as possible to reduce signal attenuation.
(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 not required.

(9) This completes the configuration requirements of the AIS. The next step involves
checking the system linkup to ship’s dGPS and Gyro. To check these links you
must enter the Own Ship Data screen of the interface.
(10) Enter FNC and then ENT. This will get you to Own Ship Data screen. The screen
will display ship positional and heading information.
(11) Confirm ship positional data, heading and SOG/COG/ROT data is correct by refer-
encing the equipment repeater display.
The AIS is now placed in service. It is to remain operational at all times when the
vessel is operating unless given specific authorization to discontinue operation by
local maritime authorities. The only interaction with the interface will be to view surrounding ship traffic identification information and to enter voyage specific data at
the start of each voyage.
