1.2 Safety recommendations
➔When mounting the antenna, the distance from the antenna unit to other radiation sources e.g.
radar equipment or other antennas (mobile communication antennas) should be minimum 3 m
(11 ft).
➔Simultaneous operation of radar and satellite antenna ma damage the satellite antenna if not
installed directl above the radar antenna.
➔Do not use the ACU unit outdoors.
➔During a thunderstorm, we recommend that the connection cables are disconnected.
➔If the negative side of the antenna unit’s suppl voltage has no connection to ship’s ground
(earth), then the antenna unit’s ground point should be connected directl to ship’s ground
(earth).
➔After the installation is completed, all other electronic s stems i.e. GPS, Radar, VHF, FM, AM
etc. should be tested for full functionalit , while the antenna is turned on.
➔Do not test or turn on the antenna before the radome is fitted correctl . If the sun reflects into
the dish, the electronics can be damaged.
➔Do not touch the rotar joint.
➔Do not attempt to open the sealed electronics, as this will void the warrant .
➔Do not sta closer than 5m to the antenna during operation
➔It is not allowed to use modem configurations with less than 153,6 kHz Tx Bandwidth
(@ - 3 dB)

2.3 Selecting location
This illustration shows the importance of a proper location for the antenna unit.
Note that criteria such as an unobstructed view to the satellite and a strong mounting surface are met.
Furthermore, no sources of interference, e.g. radar equipment or other antennas, such as mobile
communication antennas, should be installed nearb the antenna unit.
Although the radome is sealed, it is recommended to avoid direct waves and bilge water!
The antenna unit has to be installed so that no superstructures will obstruct the sight to the satellite!
Please note, that the elevation angle depends on the geographical location of the boat and on the
selected satellite!
► Equally important for a good installation are the conditions of the mounting surface and the
lengths of the different cables. See section 2.4, 2.5 and 2.6.

2. Mounting surface
A horizontal, solid and stead surface is ver important. Make sure that the surface does not have an
irregularities! Furthermore, please take into consideration that the weight of the antenna unit is 56 kg
or more. Therefore, the surface has to be strong enough to carr the antenna unit, even during the most
challenging maritime conditions.
2.5 Planning the cable paths
Before starting the installation, ou should check which walls are suitable and if existing openings can
be used for the cables.
► All openings have to be sealed in order to avoid any water penetrating.
2.6 Power supply
The antenna unit is powered b the ACU using 24 V DC. The ACU is powered b a built in power
suppl , which is working on 230V AC. Max. power consumption is 150W. The circuit has to be fused
properl .
► The power distributor must be idle while working on the ship’s supply net or you may short
circuit the system.
If the chassis of the antenna unit has no connection to the boat's ground, make sure a potential
compensation between boat ground and the ground point of the antenna unit is made.
2.7 Drillings
To avoid an damage to the mounting surface it is recommended that ou start out with drilling a
smaller hole, using a 3.5-4 mm bit before drilling the correct hole size. Use an 8.5-9 mm bit to drill 4
mounting holes for the M8 screws included. To drill the holes in the correct positions, please refer to
the included template.

2.8 Mounting the antenna unit
The antenna unit has to be mounted on a solid and stead base parallel to the water surface. Take care
that the cable lengths are sufficient, the antenna unit must have an unobstructed view to the satellite
and there must be no interference fields (especiall mobile communication antennas) nearb .
Place the antenna unit on the pre-drilled holes and fasten it with the included screws and washers. The
screws have to be screwed in from below through the mounting surface into the radome.
► Close all drillings with waterproof sealing material to avoid any water penetrating!
2.9 System cable connections
► Break the contact of the circuit on which you are working to avoid short circuit the system.
●The antenna cables (Power, RX and TX) must be connected to the ACU and the antenna unit.
●The ACU has to be connected to 230VAC 50/60Hz
●The users network is connected to the frontside or backside LAN connector of the ACU
See s stem overview and illustration details.
Lead the cable through the drilled holes and seal it with waterproof sealing material. Furthermore, drip
loops should precede the entr point from the exterior to avoid an water penetrating, see below
illustration:
Find a suitable location for all units within cable lengths. Take care that the displa of the ACU can be
easil read and the push-buttons are accessible. And also, allow room for the cables behind the ACU!
The antenna unit is separated from the power suppl net b the ACU. Therefore, the antenna unit has
electric power when the ACU is turned on!

1. Put bushing and chuck onto the cable.
2. Prepare cable as shown above.
3. Insert the wire into the terminals and fasten the clamping device b a flat screw
driver.
4. Push insert and chuck into housing (pa attention to the guiding ke wa !).
5. Fasten bushing b means of a fork wrench 3/4”, min. Torque 2.5 Nm (1.8 lb-ft).

3 Control elements
3.1 ACU
The operation of the EPAK-SatCom s stem is controlled from the ACU (19'', 2 HU). It is a good idea
if ou make ourself familiar with the ke functions and the indicators:
Ke s:
POWER : Switches on and off the power for the whole unit
BROWSE : Short press will browse through all available menus, step b step or cancel an
operation.
ENTER : Short press will select/confirm what is written in the displa .
Indicators:
CPU : CPU is running
ODU : Status of power connection to antenna
Green – ODU is powered,
Red – Short or other error,
White – ODU is not connected
BUC : Status of transmit unit (Block Up Converter)
Green - BUC is working
Red - Short or other error,
Blue - BUC is not connected
LOCK: Antenna has locked on correct satellite
LAN : a PC or router is connected to the ACU
WAN : Modem is online
Connectors:
WAN : Connection to the modem
LAN : Connects a PC or router to the ACU
3.2 Preparing the network behind the ACU
On the LAN interface it is possible to configure a DHCP server or static IP addresses. To connect
more then one PC, ou can use a simple Switch (a Router is included in the ACU).

Satellite Antenna searches for satellite.
Satellite Antenna has found the satellite and tracks it.
When the satellite has been found and identified correctl , the indicator LOCK will be lit. The
indicator LAN is on, when a PC or router is connected on the LAN port of the. When the modem has
connected to the internet, the WAN indicator is on.
.2 Preset
In the first time installation a preset has to be done. This means, after power on and after the message
complete, press BROWSE (displa Preset?) and then ENTER. Then a list of preprogrammed
satellites is shown, which can be browsed b pressing the BROWSE button. B pressing ENTER the
actual shown satellite will be selected. B pressing ENTER the compass will be calibrated
(calibrat is shown in the displa ). In order to deactivate the compass (which is likel needed on
steel ships and/or a steel made mounting platform), press the ENTER button for a long time as soon as
the displa shows scanning. After 4 seconds Compass / Off is shown and b pressing
ENTER the compass will be switched off. B pressing BROWSE the compass will be used. Now the
satellite will be searched (scanning/Satellite in the displa ) and stored if found.
This step can take a few minutes.

APPEND CES
A Maintenance
The satellite tracking s stem EPAK-SatCom does not require a lot of maintenance. The following
instructions are sufficient to sustain the optimal capacit of the antenna unit:
•Clean the radome once a month, using fresh water and a mild detergent to remove dirt and salt
deposits.
•Do not detach the radome!
•Do not spra directl on the radome with high pressure water from a hose!
•Check cable connections to be tight and free of corrosion. Clean the cables regularl .
The radome has a protective la er of UV-stabilized and maritime climate-proof lacquer. Do not appl
an additional paint, wax, preservative, solvent, chemicals or adhesive labels. An kind of coating will
void warrant claims!
In case an solvent comes in contact with the radome b accident, rinse the area immediatel with
water and, if necessar , with a mild detergent!
