Safety Warnings, Cautions and Warranty
General
To avoid interference, do not run cables parallel toAC wiring, or near fluorescent lights or
other high magnetic or electrical fields. Interference from this kind of sources causing
equipment to be faulty or fail working properly will automatically void warranty conditions.
Access to the interior of the equipment shall be made by a Nera qualified technician only.
The equipment shall be installed by a Nera SatCom approved Installation & Service
Agent.
Warranty is not valid until the "Nera Satcom AS Warranty Certificate" (at the back of the
Registration and Warranty Certificate booklet enclosed with the equipment) is signed by
the approved Installation & ServiceAgent, and returned to Nera SatCom.
Grounding
Grounded AC power socket shall be installed near the equipment and shall be easily
accessible. Connection to all type of equipment meant for operation of the unit should be
done while the unit is powered off. Peripheral equipment using mains shall be connected
to a grounded AC power socket.
Cables and connections
Cables longer than 5 metres must be shielded. All peripheral equipment must be
grounded.
Cables exceeding their maximum lengths require special arrangements, cable extenders,
short haul modems etc.

interface.
Ventilation of the Below Deck Equipment
Ambient temperature range: 0 - 45oC.
To ensure adequate cooling of the MCU a 10 cm unobstructed space must be main-
tained above and below the unit.
When wallmounted, ensure sufficient space above the MCU to permit removal of the
Modem Unit and Power Supply Unit.
See "Placing the Main Communication Unit (MCU)".
Failure to comply with the above rules for installation will automatically
void the warranty.

Below Deck Equipment - BDE
Main Control Unit The Nera F77 Main Communication Unit (MCU) - which
constitutes the major electronic part - is designed for wall or
desktop installation. The MCU supplies 48 VDC power to the
ADE through the coaxial cable.
The MCU mains input is 100 - 240 VAC ±10%. The power
requirement is approx. 40 W in receive/idle mode, and
approx. 150 W in transmit mode.
A CD supplied with the equipment contains a program for
control and operation from PC. See the Nera F77 - User
Manual.
Nera ISDN Handset The Nera ISDN Handset keypad and built-in display allows
dialing and control of the MCU and antenna.
Distress Alarm The Distress Alarm Unit together with the Nera ISDN Hand-
set provides remote activation of an alert transmission and
indication of incoming distress calls.

Placing the Antenna
Radome type Nera F77 is delivered either with mast mounted or deck
mounted radome. See previous page.
The mast mounted version includes a hatch which provides
access for service and repair, whereas on the deck mounted
version the radome top must be lifted off before servicing.
Avoiding obstructions The antenna has a beamwidth of ±7.5 degrees and ideally
requires a free line of sight in all directions.
Any obstruction will cause blind sectors, resulting in signal
degradation or even loss of communication with the satellite.
Degradation of the satellite signal can only be completely
avoided by placing the antenna higher than any obstructions.
This is often not feasible and a compromise must be made to
reduce the number of blind sectors and cost of installation.
The degree of signal degradation depends on the size of the
obstructions; the distance to them must therefore be consid-
ered.
Preferably, all obstructions within 3 m of the antenna should be
avoided. Obstructions less than 15 cm in diameter can be
ignored beyond this distance.
Radiation precautions Passengers should not be admitted in areas closer than 5 m
from the antenna.
However, no restrictions are required when the antenna radome
is installed at least 2 m above the highest point accessible to
passengers.
Personnel should not be close to the antenna for periods of more
than 1 hour per day without switching off the RF transmitter.

PLANNING
Nera F77
Continuing the Saturn tradition
Avoiding interference Do not locate the antenna close to interfering signal sources, or
in such a position that the source (e.g. radar-antenna) radiates
directly into the Nera F77 antenna.
The Above Deck Equipment (ADE) should be separated as far
as possible from other transmitters, and preferably by at least
5 m from the antenna of other communication or navigation
equipment, such as the antenna of the satellite navigator, the
VHF antenna, radar equipment, or other Inmarsat equipment.
Compass safe distance For installation on British or Norwegian vessels, the antenna
should be located at a distance of at least 1.0 metres from the
magnetic steering compass. Be aware that requirements may
vary from one country to another.
Other precautions Do not place the antenna close to the funnel, as smoke depos-
its will then eventually degrade antenna performance.
The antenna should be installed so that severe vibration and
shock are avoided.

Designing the Antenna mast (mast mounted version)
The mast must be designed to carry the weight of the antenna
forces of up to 120 knots on the radome as well as the onboard
vibration levels. The radome is 1.076 m high and has a maxi-
mum diameter of 1.165 m.
The top end of the mast should be fitted with a flange with holes
matching the bolts extending from the bottom of the radome.
See figure below. The flange must not be so large as to inter-
fere with the hatch at the bottom of the antenna unit.
NOTE: On ships with excessive vibration the mast must be
supported by stays or other adequate means.
If the height of the mast makes it necessary to climb up to the
antenna unit, a ladder must be provided on the mast column. A
guard rail must be attached to the upper section for safety
purposes. If the height of the mast exceeds approximately 4.5
metres, an access platform should be attached to the mast
approximately 1 metre below the radome bottom.
Be aware that requirements may vary from one country to
another.

Placing the Main Communication Unit (MCU)
The Main Communication Unit should be placed in a ventilated
area. To ensure adequate cooling of the MCU a 10 cm unob-
structed space must be maintained above and below the unit.
A space of 10 cm above the
MCU is also required to
allow removal of units.
For grounding, see
"Grounding considera-
tions" and "Location and
grounding of units".
Ambient temperature range
0O-45
OC.
The MCU is manufactured as
a cabinet for wall or desktop
installation with dimensions
as shown. Six holes through
the MCU mounting plate
allows the unit to be secured
to the wall or desk top.
Placing the Distress Alarm Unit & Nera ISDN Handset
The Distress Alarm Unit is operated in conjunction
with a Nera ISDN Handset.
The Nera ISDN Handset functions as a
display and communication unit for alert
transmission. It may also be used for normal
voice communication.
Up to two (2) Distress Alarm Units, together
with Nera ISDN Handsets, may be connected
in series. The units may be installed anywhere
onboard the vessel.
Four separate ISDN ports (part of the ISDN
bus) are available on the MCU as RJ45 jacks
or screw terminal blocks.
Max cable length: 100 m
See "ISDN telephones/equipment and ISDN cable lengths".
Placing the Nera ISDN Handset as a standard telephone
The Nera ISDN Handsets may be installed as
standard telephones without Distress Alarm units.
The units may be installed anywhere onboard the
vessel. Four separate ISDN ports are available on
the MCU as RJ45 jacks or screw terminal blocks.

Placing the telefax machine
A digital telefax (Group 4) can be con-
nected to the ISDN bus for transfer at
64 kbps rate.
An analogue telefax (Group 3) can be
connected to the TEL4 port (default
9.6 kbps fax).
(3.1 kHz audio can also be used for
Group 3 fax, providing typically
14.4 kbps transfer speed.)
Placing the PC A PC w/ISDN card can be con-
nected to the ISDN bus for 64 kbps
rate data communication up to
100 m away from the MCU.
A PC connected to the USB/RS-
232/RS-422 port can also be used
for control and configuration of the
Main Communication Unit. This
requires that the vtLite Marine
program accessible on the Nera F77
CD is installed.
Connection to the USB/RS-232/RS-422 port also allows
64 kbps data transmission.
See the User Manual.
Cable lengths:
• ISDN port: see "ISDN telephones/equipment "
and "ISDN cable lengths"
• USB port:
• RS-232 ports: see "Appendix 8, cable pinouts"
• RS-422 port:
Placing analogue telephones
Analogue 2-wire telephones can be installed
anywhere onboard the vessel.
Four separate analogue ports TEL1-TEL4
are available on the MCU.
TEL3 and TEL4 are in addition available
as RJ45 jacks.
Two telephones can be connected in parallel
on each line, providing a maximum of eight
analogue telephones.
