Safety and Warranty 1
General
All cables for the Fleet55/77 system are shielded and should not be affected
by magnetic fields. However, if possible do not run cables parallel to AC
wiring – failing to do so might cause the equipment to be faulty or working
properly.
Service
User access to the interior of the BDU unit is prohibited. Service may only be
performed by a technician authorized by Thrane & Thrane A/S - failing to do
so will void the warranty. Access to the interior of the ADU is allowed, but
only for replacement of certain modules - as described in this manual.
General service may only be performed by a technician authorized by Thrane
& Thrane A/S - failing to do so may void the warranty.
Radar safety distance
Do not move the ADU closer to radars than the minimum safety distance
specified in this manual - this will possibly damage the ADU eventually.
Equipment must be installed with a minimum safe distance to magnetic
steering compass of at least 1.25 m. Personal safe distance is 4 m from the
F77 ADU and 2 m from the F55 ADU while it is transmitting.
Grounding, cables and connections
The BDU unit shall be connected to the ground of the ship via the Antenna
Pigtail Cable and the Grounding Kit (Accessories). Further, the BDU must be
grounded at its grounding stud.
The ADU shall be grounded to the ship via one or more of its mounting bolts.
The shielded cables must generally be grounded in both ends, except for the
cable between BDU and Cradle, which shall not be grounded in the Cradle
end.
Page 4
iv
Connections of all types of equipment must be done while the unit is
switched off. For further grounding information read Appendix G Grounding
and RF protection on page 105.
Do not extend the cables beyond those specified for the equipment – except
from the cable between the BDU and ADU. The cable between the BDU and
ADU can be extended if it complies with the specified data concerning cable
losses etc.
Power supply
Operation voltage is 24 V DC. Note that long-term operation below 24 V DC
should be avoided.
It is recommended that the voltage is provided by the ship hot 24 V DC power
bus.
Be aware of high start-up peak current. 16 A@24 V, 15 ms.
Maximum operational peak power requirement for F77/F55 is 240/200 W
and maximum average power consumption is 180/150 W.
If a 24 V DC power bus is not available, an external 115/230 VAC to 24 V DC
power supply can be used.
Equipment ventilation
To ensure adequate cooling of the BDU a 5 cm unobstructed space must be
maintained around all sides of the unit (except the bottom side).
BDU ambient temperature range: -15° to +55°C.
Failure to comply with the rules listed above will void the warranty!

System Units 1
1.1 Introduction
The basic system consists of four units: The Below Deck Unit (BDU), The
Control Handset, The Cradle and The Above Deck Unit (ADU).
1.2 Below Deck Unit – BDU
The Below Deck Unit (BDU) – which contains the primary electronic parts – is
designed for wall or desktop installation. The BDU supplies 42 VDC to the ADU
through a single coaxial cable. The F55/F77 BDU power requirement is
240/200 W peak and 180/150 W average at 24 VDC. The power shall be
provided by the ship hot 24 VDC power bus, or by an external VAC to VDC
power supply (minimum 10A). Be aware of high start-up peak current.

Chapter 1: System Units
2Display Handset
1.3 Display Handset
The Display Handset allows dialling and control of the BDU and the antenna.
1.4 Distress Cradle
The Distress Cradle, which holds the Display Handset, provides activation of
alert transmission. The distress cradle may only be used for F77.
1.5 Passive Cradle
The Passive Cradle, which holds the Display Handset, provides no activation of
alert transmission. The passive cradle may only be used for F55.
1.6 Above Deck Unit – ADU
The antenna (ADU) consists of a stabilized antenna with RF-unit and an
antenna control unit, with GPS (ACU). All communication between the ADU
and BDU goes through a single coaxial cable. The antenna unit is protected by
a fibre glass radome - access to the interior of the ADU is possible through a
hatch located at the lower part of the radome.

GMDSS Installations 2
2.1 Requirements
(Not applicable for Fleet55 installations).
The International Maritime Organization (IMO) has set out requirements on
how the Fleet77 should be integrated in a Global Maritime Distress and Safety
System (GMDSS) installation:
IMO Resolution MSC.130(75).
IMO Resolution A.888(21).
2.2 Distress call initiation
For the installation to comply with IMO Resolution (MSC.130/A.3.2), it will
need to include a distress cradle and handset fitted on the bridge, as well as in
the radio communications room if applicable, for the ability to initiate distress
calls.
2.3 Maritime Safety Information
The TT-3084A Sailor Fleet77 meets the voice requirements of IMO Resolution
A.888(21). To meet the GMDSS carriage requirements of SOLAS (Safety Of Life
At Sea) in respect of receipt of SafetyNET broadcasts carrying MSI (Maritime
Safety Information) and direct printing telegraphy, it is necessary to install a
combined INMARSAT C/EGC transceiver in addition to the INMARSAT F77
equipment.
Page 14
Chapter 2: GMDSS Installations
4 Power Supply
2.4 Power Supply
For the installation to comply with IMO Resolution (MSC.130/A.5.1), a Fleet77
forming part of a GMDSS installation needs to be able to switch between two
power supplies, a main and a backup source, where during main power
source failure, the Backup source normally would be automatic switched in
and maintain the Fleet77 system fully operational.
A power source change-over unit is not incorporated in the Fleet77 equipment
and thus is needed externally.
In principle there are two ways in which the required power supply back up
can be obtained:
1. “Hot” connection to the ships emergency batteries.
In this case the Fleet system is connected “directly” to the batteries and
the associated charger, and the charger supplies the power required for
the Fleet system. This ensures true “no-break” power supply for the Fleet
system. It is of cause necessary that the charger is powerful enough to
supply the power for the Fleet system, plus other systems which might be
connected to the batteries, such that the batteries are not discharged.
Be aware of high start-up peak current. 16 A@24 V, 15 ms.
Maximum operational peak power requirement for F77/F55 is 240/200 W
and maximum average power consumption is 180/150 W.
2. “Cold” or “switch-over” connection to the ships emergency batteries.
In this case the Fleet system is normally supplied from the ships AC line
(115 or 230 V) through an AC to DC (24-28 V) power supply. In case of loss
of line voltage the Fleet system power input is, either manually or
automatically, transferred to the emergency batteries. In many cases the
AC/DC power supply includes battery input and a relay for automatic
battery switch-over.
Page 15
Chapter 2: GMDSS Installations
Power Supply 5
2222
Any interruptions on power sources possibly from power supply switch-over,
must be cleared within 60 seconds, for the Fleet77 to enable automatic powerup and re-initialization. Furthermore, if a power interruption can be kept
below 20 ms, it can be guaranteed that a call (e.g. a distress call) will not be
disconnected during this. As it could be critical to maintain a call during an
emergency situation, it is strongly recommended that the power back-up
installation is made such that switch-over takes less than 20 ms.
The AC/DC power supply TT-3680F provided by Thrane & Thrane A/S, is usable
for GMDSS installations, and is capable of automatic switch-over to battery
power in less than 20 ms.

Placing the Antenna 3
3.1 Obstructions
The antenna rotates 360° and down to –25° in pitch and roll to allow for
continuous pointing even during the worst sea states. Any obstructions within
this volume can cause signal degradation.
The amount of degradation depends on the size of the obstruction and the
distance from the antenna. As a rule of thumb any obstruction, which
subtends an angle of less than 3° at the antenna will have limited effect. The
table below gives a guideline for obstruction sizes, which will cause limited
degradation.

8 Radiation Hazard
3.2 Radiation Hazard
The F77 antenna radiates 32 dBW EIRP (including 20 dBi antenna gain). This
translates to a minimum safety distance of 4 m from the antenna while it is
transmitting. This is based on a radiation level of 0.8 mW/cm
2
. The F55
antenna has a safety distance of 2 m.
For higher radiation level, see the table below.

Interference 9
3333
3.3 Interference
The ADU (antenna) must be mounted as far away as possible from the ship’s
radar and high power radio transmitters (including other Inmarsat based
systems), as these can compromise the ADU performance. RF emission from
radars might actually damage the ADU.
As the Fleet ADU itself is a quite powerful transmitter, this on the other hand is
also capable of disturbing other radio systems. Especially, other Inmarsat
systems and GPS receivers with poor frequency discrimination are vulnerable
to the radiation generated by the Fleet ADU.
Page 20
Chapter 3: Placing the Antenna
10 Interference
3.3.1 Radar
It is difficult to give exact guidelines for minimum distance between a radar
and the ADU – as radar power, radiation pattern, frequency and pulse
length/shape varies widely from radar to radar. Further, the ADU will typically
be placed in the near field of the radar antenna and reflections from masts,
decks and other items present in the vicinity of the radar will be different from
ship to ship.
Despite the issues mentioned above, the guidelines below can be given:
Since a radar radiates a fan beam with a horizontal beam width of a few
degrees and a vertical beam width of up to +/- 15°, the worst interference can
be avoided by mounting the ADU at a different level – meaning that the ADU is
installed minimum 15° above or below the radar antenna. Due to near field
effects the benefit of this vertical separation could be reduced at short
distances (below approximately 10 m) between radar antenna and ADU.
Therefore it is recommended to ensure as much vertical separation as possible
when ever the ADU has to be placed close to a radar antenna.
Page 21
Chapter 3: Placing the Antenna
Interference 11
3333
3.3.2 ADU damage
The minimum acceptable separation (d min.) between a radar and the ADU is
determined by the radar wavelength/frequency and the power emitted by the
radar. The tables below show some “rule of thumb” minimum separation
distances as a function of radar power at X and S band. If the “d min.”
separation listed below is applied, ADU damage will normally be avoided.
“d min.” is defined as the shortest distance between the radar antenna (in any
position) and the surface of the Fleet ADU.
The separation distance for C-band (4-8 GHz) radars should generally be the
same as for X-band radars.
X-band (~ 3 cm / 10 GHz) damage distance
Radar power d min. at 15° vertical
separation
d min. at 60° vertical
separation
0 – 10 kW 0.8 m 0.4 m
30 kW 2.4 m 1.2 m
50 kW 4.0 m 2.0 m

Radar power d min. at 15° vertical
separation

30 kW 1.0 m 0.5 m
50 kW 2.0 m 1.0 m
Page 22
Chapter 3: Placing the Antenna
12 Interference
3.3.3 Interference
At distances further away than “d min.” given above the radar might still be
able to degrade the performance of the Fleet system.
The presence of one or more X-band radars within a radius up to around
100 m could cause a minor degradation of the signal to noise ratio during high
speed and data calls. The degradation will be most significant at high radar
pulse repetition rates.
As long as receiving conditions are favorable, this limited degradation is
without importance. However, if receiving conditions are poor – e.g. due to
objects blocking the signal path, heavy precipitation or icing, low satellite
elevation and violent ship movements – the small extra degradation due to the
radar(s) could cause poor call quality. A speech call might become noisy and
perhaps fail while a data connection might decrease in speed and
performance.
The presences of S-band radar(s) are unlikely to cause any performance
degradation – as long as the minimum distances (d min.) listed above are
applied.
It is strongly recommended that interference free operation is verified
experimentally before the installation is finalized.
3.3.4 Other Inmarsat systems
Recommended minimum safe distance to other Inmarsat antennas is 10 m.
3.3.5 GPS receivers
Good quality GPS receivers will work properly very close to the ADU - typically
down to one meter outside the main beam, and down to a few meters inside
Warning! The ADU must never be installed closer to a radar than
“d min.” - even if experiments show that interference free operation
can be obtained at shorter distances than “d min.” given above.

3333
the main beam. However, simple GPS receivers with poor frequency
discrimination could be affected at longer range (typically 10 m). It is always
recommended to test the GPS performance before the installation is finalized.
3.3.6 Other transmitters
See Minimum Recommended Distance to Transmitters. on page 88 in
Appendix B for minimum recommended distance to transmitters in the
frequency range below 1000 MHz.
3.3.7 Other precautions
Do not place the ADU close to a funnel, as smoke deposits are corrosive.
Furthermore, deposits on the radome can degrade performance.
Page 24
Chapter 3: Placing the Antenna
14 Antenna Mast Design
3.4 Antenna Mast Design
The antenna mast must be designed to carry the weight of the antenna unit,
which for F55 is approximately 18 kg and for F77 is approximately 27 kg.
It must also be able to withstand wind forces up to 140 knots on the radome as
well as onboard vibrations.
The top of the antenna mast should be fitted with a flange with holes matching
the bosses in the radome. The flange diameter must be less than 380 mm in
order to avoid interference with the F77 hatch and the antenna beam.
The flange thickness must be at least 10 mm. The antenna is to be mounted on
the flange by means of 4 M10 bolts. The bolt engagement shall be 15 ±5 mm.
Drill a hole in the centre of the flange for radome drain pipe.
See Outline Dimensions, Flange on page 87 in Appendix B.
The holes in the flange must be positioned symmetrically around the
longitudinal axis of the ship, to ensure the correct heading of the antenna. See
Appendix B F55/77 ADU Technical Specifications on page 81 for heading mark.
The Antenna tracking system is directional why the heading direction of the
ADU is extremely important, as setting the wrong heading will cause the
antenna to lose track of the satellite as soon the ship start to move.
In some cases it may be necessary to install the antenna such that it is
misaligned to the ship, e.g. to insure F77 hatch accessibility. Compensation for
mount pos can only be done in steps of 90°. See User Manual chapter 4 “Ant.
Setup”. Antenna Set-up for installation angle set-up in case the angle is
different from the default 0°.
The F55/F77 heading is defined by the ADU N-type connector placement. For
the F77 the hatch may be used for locating the heading direction as well.
Page 25
Chapter 3: Placing the Antenna
Antenna Mast Design 15
3333
The F55/F77 value of the installation angle is defined as shown below (seen
from above ship).
Long-term, trouble free operation depends on good mast design avoiding
severe shocks and vibration levels. As every ship has unique structural
characteristics, it is difficult to give specific design rules. Nevertheless, every
attempt should be made to design a mast which has a natural frequency
>25 Hz (i.e. stiff) to avoid the majority of the ships vibration spectrum.
The table below gives some suggested design values for the free part of the
pole mast.

High masts or installations on ships with high vibration levels should be
further stabilized by stays from the mast flange.
Note
Stays and stiff masts can still not prevent vertical vibration if the mast
is attached to a deck plate that is not stiff. Every effort should be
made to mount the mast to an area that is well supported by ribs. If
this is not possible, extra deck plate stiffening should be provided.

Installing the ADU 4
4.1 Unpacking
Open all boxes supplied and check the contents with the enclosed packing list.
Inspect units and parts for possible transport damage.
4.2 Preparation
The antenna is supplied in a cardboard box and is bolted to a pallet. Cut the
straps around the sides, remove the lid and take the sides off by lifting over
the radome. The antenna system can be removed from the pallet by removing
the 4 M10 screws from underneath.
4.3 Grounding
It is recommended that the antenna is grounded via its mounting bosses to its
mounting plate as the RF coax screen and antenna electronics ground are
referenced to this point.
The metal underneath the head of at least one bolt must be clean of insulating
protective coating and a serrated washer should be used. After the bolts are
tightened, it is recommended that the area is suitably sealed in order to avoid
corrosion of the grounding point.
It is recommended that all 4 bolts are used for grounding. Use stainless steel
bolts and washers.
For further grounding information read Appendix G Grounding and RF
protection on page 105.

Chapter 4: Installing the ADU
20 ADU cables
4.4 ADU cables
The coaxial cable for connection between the antenna and BDU is not part of
the basic system. Make sure that a sufficient length of cable is ordered. See
Appendix A Part numbers on page 77 for cable options.
Select a suitable area for installation of the BDU, ADU and Cradle. Where
exposed to mechanical wear - on deck, through bulkheads, etc. - steel pipes
should protect the cables. Standard procedures should otherwise be followed
for cabling in ship installations.
The maximum allowed RF-loss in the Antenna cable is 10dB@1660 MHz. This
is to ensure the performance of the system. The Cable loss can be read in the
handset.
The Cable loss readout will vary mainly due to Temperature changes in the
ADU. In Table 1 below, the maximum allowed Cable loss readout are listed.
During installation the Cable loss readout shall be checked. If the Cable loss
readout is above the specified maximum values the installation has to be
checked.
ADU temp. -25°C +22°C +65°C

Recommended Antenna Cables:
Furthermore it has to be checked in the data sheet from the cable supplier,
that both the RF- attenuation and the DC-resistance are kept within the
maximum specified values:
• Antenna Cable RF-attenuation max: 10 dB excl. connector.
• Antenna Cable loop DC-resistance max: 0.54 Ω.
Also it has to be ensured that the specified minimum bending radius is
respected. If this is not the case, the loss in the cable will increase. Check the
instruction from the cable supplier.
The coax cable can be extended if it complies with the specified losses listed
below.
• Maximum RF loss, 1525 - 1660 MHz: 10 dB
• Maximum DC loss, R loop: 0.54 Ω
• Maximum RF loss, 3.5 - 4.0 MHz: 2 dB

22 Mounting
4.5 Mounting
The radome can now be installed on the mounting plate on the ship via 4 M10
stainless steel bolts. In case of F77 the hatch must face the stern of the ship.
If it is necessary to alter the mount position relative to the ship (90, 180 or
270°, and to ensure hatch accessibility), the “mounting pos” has to be
adjusted, this can be done via the Display Handset.
See User Manual chapter 4. “Ant. Set-up” for “mounting pos” adjustment.
The only electrical connector is a single N-Type connector on the lower
radome.
4.6 Important notes
Do not re-use any of the M10 screws from the pallet. The bolt thread must not
penetrate more than 20 mm - and not less than 10 mm - into the bosses of the
radome. The bolts must be tightened to 25 ±5 Nm.
After having connected the antenna cable to the ADU - ensure that the
connector assembly is properly protected against seawater and corrosion. As a
minimum, it is recommended that self-amalgamating rubber tape is used.

Installing the BDU 5
5.1 Where to place the BDU
The BDU must be placed in a ventilated area. To ensure adequate cooling of
the BDU a 5 cm unobstructed space must be maintained around all sides of
the unit (except the bottom side).
Ambient temperature range is –15° to +55°C.
The BDU is manufactured as a cabinet for bulkhead or desktop installation.
The cabinet is equipped with two mounting brackets, which makes it possible
to secure the unit on a bulkhead.
See Outline dimensions on page 92 in Appendix C.
The BDU and all external units delivered by Thrane & Thrane A/S must be
placed with a minimum safe distance of at least 1.25 m to magnetic steering
compass.
Note
It is very important that the BDU is placed in an area where access to
the hull or equivalent grounding can be reached within 0.5 m.
Page 34
Chapter 5: Installing the BDU
24 Grounding the BDU
The unit that has the largest impact on magnetic steering compasses is the
distress cradle, since it contains a magnet, which holds the display handset.
Minimum safe distance is 1.25 m – but if possible, place the distress
cradle/handset further away from magnetic steering compasses.
5.2 Grounding the BDU
The antenna cable (4) is connected to the BDU by means of a coax “pigtail”
(3).
The pigtail is connected to the BDU by a TNC-connector (male) and to the
antenna cable by an N-connector (female). The pigtail must be grounded at
the N-connector end – use the grounding kit (2) to mount the cable on the hull
or other common ground.
To ensure that the BDU is grounded – also if the pigtail is disconnected from
the BDU, an extra ground wire must be connected. The ground wire is
connected to the BDU by an M3x6 screw. The grounding point is located next
to the power plug (1).
In some cases it is not possible to access the hull and at the same time place
the BDU in a suitable place.
The pigtail is only 0.5 m long and extension is not allowed.
Page 35
Chapter 5: Installing the BDU
Grounding the BDU 25
555
A way to insure good grounding and at the same time make it possible to
ground the pigtail - is to extend the ship ground plan by means of copper foil.
The maximum length of the foil is determined by the width of the foil.
Copper foil 5 cm wide: Max 50 cm
Copper foil 10 cm wide: Max 100 cm
Copper foil 20 cm wide: Max 200 cm
Connect the foil to the hull by plenty of screws or hard–soldering. Run the foil
past the place where the pigtail is to be grounded and mount the grounding
kit on top of the foil.
For further grounding information read Appendix G Grounding and RF
protection on page 105.
Note
The foil must be at least 0.1 mm thick.

Connecting Power 8
8.1 Power cable selection
The length of the BDU power cable depends on the type of cable used and the
source impedance of the ship’s 24 V DC installation. It is required that the total
source impedance at the BDU does not exceed 250 mΩ.
Select a power outlet from the ship’s 24 V DC system, and measure the source
impedance of the ship installation as described in Measuring the Ship Source
Impedance on page 93 in Appendix C.
If a 50 mΩ ship source impedance is measured, only 200 mΩ is left for power
cable loop resistance, since the total source impedance should be below
250 mΩ (250 mΩ - 50 mΩ = 200 mΩ).
For further recommendations on power cable selection, see the appropriate
section on the next page, depending on which power connector the BDU is
fitted with:
• BDU fitted with the old 4-Port power connector: See section 8.1.1 Old 4-port
power connector.
• BDU fitted with the new Sub-D power connector: See section 8.1.2 New
Sub-D power connector.
Note
If the total source impedance is higher than 250 mΩ, the terminal
may start to On/Off oscillate.
Page 48
Chapter 8: Connecting Power
38 Power cable selection
8.1.1 Old 4-port power connector
(Only applicable for old 4-port power connector).
To make sure that the power cable fits the power connector the dimensions of
the cable must be:
• Cable outer diameter max 3 mm
•Inner core 1.5mm
2
The cable inductance should not exceed 5 µH. If the inductance is too high,
the power supply may start to oscillate.
To minimize the cable inductance a multi 2- or 4-wire cable should be used.
Recommended power cable types and length:
The power connector has the option of running four cables instead of two,
which allows the cable to be twice as long.

Cables with larger cross-section area than 1.5 mm2 may be connected to the
BDU by use of the pigtail that is supplied with the system.
By use of this pigtail, you may extend the cable length as long as you keep the
total source impedance < 250 mΩ and cable inductance < 5 µH.
The BDU is equipped with an internal 10 A thermal circuit breaker, therefore
no external fuse is necessary in order to protect the BDU. However, in order to
avoid short circuit in the power cable/connector, the ships DC outlet should be
protected by a 10-15 A fuse or circuit breaker. If the automatic circuit breaker
pops out check the power supply polarisation.

to the recommendations below:
The BDU is equipped with an internal 15 A Fuse, therefore no external fuse is
necessary in order to protect the BDU. However, in order to avoid short circuit
in the power cable/connector, the ships DC outlet should be protected by a 1520 A fuse or circuit breaker.

Service and Repair 11
11.1 Introduction
The Thrane & Thrane Fleet systems are designed to operate without preventive
routine maintenance.
Although the system is designed and built very service friendly, we strongly
recommend that any acting service technician has been trained specifically on
the product. Repairs or repair attempts performed by unqualified personnel
may limit the warranty.
The warranty on the system is defined and outlined by the Distributor that
supplied the system.
For further information on warranty and service, you may also use the Thrane
and Thrane home page at http://www.thrane.com.
11.2 Modules
Repairs inside the BDU is not recommended to be carried out on board,
instead the unit should be replaced if defective and repaired at a qualified
workshop on shore. With the Configuration module that contains the Inmarsat
identity, it is easy to exchange a defective BDU with a working unit.
For exchange of Fleet55 modules you need to remove the top of the radome.
For Fleet77 it is not necessary to remove the top of the radome, as all modules
can be replaced via the service hatch. The modules are easy to replace and no
reconfiguration of the system is needed after servicing.

Troubleshooting 12
12.1 Error messages
If the ADU should fail an error message will be sent to the Error log. See User
Manual chapter 4 “Operation” and 2.6 “The Handset”.
The error message does not pinpoint the exact location of the unit, which is
causing the fault – but it gives an idea of where to start troubleshooting. The
error message can be hardware or software related.
If an error message is received - start the troubleshooting by restarting the
system.
If other error messages than those shown in the table are received – contact
supplier or Thrane & Thrane for Support.

212121212
12.2 Handset Com Error troubleshooting
procedure
Step 1: Check alarm log
Check for any active/recent alarms. E.g. low voltage may cause the error and
therefore look for any low voltage alarms.
Step 2: Below deck (BDU, Handset, Cradle) or Above deck (ADU) error?
1. Remove power
2. Disconnect antenna cable
3. Reinstall power
4. Switch on system (disregard “Antenna link down” error”)
Does “Handset Com error” still appear? If yes, it is a below deck error. If no, it
is an above deck error.
Step 3 (if Below deck error): Cradle, Handset or BDU error?
1. Check/replace Handset
2. Check/replace Cradle
If these replacements do not remove the error return defective BDU for repair
Page 86
Chapter 12: Troubleshooting
76 Handset Com Error troubleshooting procedure
Step 3 (if Above deck error): ACU, cable or power error?
1. Switch system off.
2. Connect the antenna cable.
3. Switch system on.
4. In antenna:
• Check the DSP LED (flash). If no, check 40 V to ADU.
• Check BITE Error LED (off). If no, replace ACU.
• Check the RX LED (flash). If no, check com cables.
