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.

ProTec AIS Introduction
1.1. General
The L-3 ProTec is an Automatic Identification System transponder which is fully com-
pliant 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 identifi-
cation system for commercial mariners. The Transponder is a fully automated sys-
tem which ties into ship’s navigational instruments to provide automatic transmission
of ships identity, status, and maneuvering intentions via standard marine VHF com-
munication techniques. Sequencing of transmission between all vessels within VHF
range is provided through SOTDMA controlling software to handle high traffic vol-
ume 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 Ves-
sel/Voyage data as required.
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 simplify-
ing 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, train-
ing, and techniques, therefore, such PWAs are not field-repairable.
As a result, maintenance philosophy for the L-3 ProTec is replacement of failed as-
semblies. In the case of the L-3 ProTec, the replaceable assemblies are the Face-
plate 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).

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 fac-
tory 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 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 alphanu-
meric 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 transpond-
er 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 posi-
tional information in NMEA format is to be fed to the transponder from the ships ex-
ternal electronic position indicating system through the supplied data cable. The in-
ternal 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 trans-
mission of position and identification and will automatically resolve scheduling con-
flicts 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 be-
gins 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, trans-
mitted 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 dy-
namic 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 transmis-
sion 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 fre-
quencies, regions of coverage, required transmission schedule and/or interrogation
request. The ProTec AIS will respond back to such DSC interrogations on the fre-
quency specified in a manner such that it does not interfere with the TDMA transmis-
sions by interleaving the transmission between TDMA transmissions. The DSC re-
sponse 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:
FMMSI number - unique referenceable identification.
FNavigation status
FSpeed over ground - 1/10 knot resolution.
FPosition accuracy - differential GPS.
FLongitude - to 1/10000 minute and Latitude - to 1/10000 minute.
FCourse over ground - relative to true north to 1/10th degree.

1.3.9. AIS Frequencies
The International Telecommunications Union World Radio Conference in 1997 desig-
nated 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 Mari-
TEL, 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 Fed-
eral Communications Commission to authorize any US vessel to operate AIS on
these two channels under its existing ship station license. The FCC released a No-
tice 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 con-
nector 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 approximately 30 miles. The Long Range mode is intended to allow the ex-
change 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 in-
tended to interface with the Long Range equipment.
The Long Range reply can be set in either:
Fautomatic mode (AUTO)
Fmanual mode L-3 ProTec (MANUAL)
Fmanual mode external application (EXT APPL).
The Long Range reply, when in AUTO mode, is made as soon as a request is re-
ceived 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 return-
ing 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 sen-
tences, LRI and LRF, refer to Table 1–5.

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 alphanu-
meric 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. The MKD is
designed to be used for configuration of the hardware, entry of vessel and voyage
specific data, and be used to monitor the AIS system. The MKD provides numerous
functions, which can be accessed via the controls located on the front face of the
ProTec AIS system. The MKD provides a fully functional menu structure that allows
the user to Logon / Logoff , configure System Information, Vessel / Voyage data, and
the Antenna Position. The user may also view Alarm Status, General Status, Down-
Time Log, and the Safety Text Log. In addition, the AIS Channels can be configured,
along with changing user passwords, setting Baud rate, adjust the LCD viewing
angle, and managing the Change Management Settings. The front face of the L-3
ProTec contains the following controls.

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.
FMount the transponder in a position which provides easy access to the key-
board and display.
FIf 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.
FIf used, Mount the transponder in the trunion utilizing the trunion knobs pro-
vided, otherwise mount transponder in flush mount bracket.
FLocate 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.
FWhen 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-
tem malfunction, or if the AIS loses power or is turned off.
Install the transponder, and complete the AIS Installation Checklist found it Ap-
pendix A, as follows:
(1) Mount the transponder. (In trunion, if used.)
NOTE: A junction box may be used in place of the terminal block.
(2) Locate an ideal position for the terminal block.

For steps (5) through (9) refer to Paragraph 3.1.2.
(5) Connect the IEC cable to data port on back of Transponder.
NOTE: 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.
(6) Lead data cables from Gyrocompass data output port to terminal block.
(7) Lead data cables from ship’s DGPS data output port to terminal block.
(8) Feed the IEC data cable to the terminal block.
NOTE: The metallic shielding of each of the three shielded cables
containing the twisted pairs must be connected to the ter-
minal 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.
(9) Connect each wire in the IEC data cable to the terminal block. (Refer to
Figure 3–3 and Table 3–2.)
(10) Connect power cable to transponder. (Refer to Figure 3–4.)
NOTE: Due to the stringent transmit attack and release times spe-
cified in ITU 1371, a robust power source is required for
proper operation. Recommended current ratings for power
sources are:
24 VDC – 10 Amp
The transponder may operate improperly if the power
source does not have the recommended minimum current
ratings.
(11) Connect power cable to ships 24 Vdc, 10 Amp minimum power supply is rec-
ommended. ( Red + , Black – )
(12) Connect the other two leads to external alarm system if desired.

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 or-
der to meet these requirements, the L-3 ProTec provides six (6) data channels to al-
low the AIS to be connected to the ships Gyrocompass and DGPS system in accor-
dance with NMEA 0183.
The L3 AIS is shipped with one IEC interface cable P/N 024M0088-01. 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. 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 chan-
nels 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).

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
024M0088-01) terminated at one end by a J4 connector. (Refer to Figure 3–2 and
Figure 3–3.) 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 sub-
scribe 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.
A junction box may be made available which terminates the data cable on the termi-
nal block and provides serial connectors to allow for easy connection to ship sen-
sors. 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 partic-
ular attention to cable routing and connector installation. Some important consider-
ations in antenna installation are:
FIn general, antennas should be located as high as practical on the vessel
and separated as much as possible from each other.
FThe VHF antenna should be placed in an elevated position with a mini-
mum of 2 meters clearance from any construction that is made with con-
ductive 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.
FIt is preferable that the VHF antenna is installed at least 3 meters away
from high power energy sources such as radar and other transmitting ra-
dio antennas, and out of the transmitting beam.
FThere 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 prima-
ry 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 3–6 and Figure 3–7.)
(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 attenua-
tion.
(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.
(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 trans-
ponder 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 instruc-
tions be followed with particular attention to cable routing and connector installation.
Some important considerations in GPS antenna installation are:
FGPS antennas should be located to provide a clear, unobstructed view of
the sky.
FGPS 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.
FGPS 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.
FThe 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.
FRecently, 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 3–6 and Figure 3–7.)
(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.
