The 4012 GX VSAT antenna:
Is based on the best 1m maritime antenna,
Has a frequency tuned radome to operate
in Ku and Ka band networks.
Uses IP based, secured communication
Has a monolithic software architecture
Has extensive diagnostic capability
Is optionally upgradable to GX
The ICU (Integrated Control Unit) is at the center of the antenna operation.
The operator interacts with this system by way of a computer (owner-supplied).
The computer communicates with the MXP (Media Xchange Processor).
The MXP communicates the operator’s commands to the ICU (Integrated Control Unit), and it passes system
information back to the operator.
The ICU controls the antenna, and monitors it.
automatically acquire the satellite from a cold (power-up) start. Once the satellite has been acquired, the modem then should
achieve lock and you should be able to use the system.
Tracking will take over (front panel
Tracking LED will be ON) and automatically
peak the antenna position for highest
receive signal level from the satellite.
When the ICU has signal above threshold
AND modem has network lock the
antenna will continue to track the satellite.
3. Satellite Name (if entered), Tracking
indicator, Modem Lock indicator and
signal level (number value and bar graph)
will be displayed in the header of the MXP
GUI pages.
Upon completion of the above, the system will
continue to operate automatically, indefinitely until:
AC power to the system is interrupted
The ship sails into an area of
insufficient satellite signal
strength/level.
If the system does NOT automatically find the satellite from a cold start, follow the steps below:
The Tracking LED will flash for a short
period of time (Search Delay) followed by
the Search LED coming ON.
The ICU will automatically move the
antenna in the selected Search pattern
until looking for a signal value that is
greater than the threshold value (red bar in
the bar graph).
Not finding a signal greater than
Threshold, the bar graph will stay red and
the antenna will reach the end of the
prescribed search pattern.
The antenna will retarget and the cycle will
repeat (Search Delay timeout, conduct
search pattern followed by retarget).
Check Latitude, Longitude and Heading.
These should be correct, but may be
updated if necessary.
Access the System Status screen.

12. Check for blockage (this is the MOST
common cause of not being able to
acquire the desired satellite).
13. Verify that the correct satellite is selected.
14. Check cable connections to assure that a
cable has not been disconnected.
If satellite signal is found but network lock is NOT achieved:

found, Tracking will take over (Tracking
LED ON) and automatically peak the
antenna position for highest receive signal
level from the satellite which has been
acquired. The system will wait for the
modem to achieve lock. If the modem
does not get lock, the antenna will resume
its search pattern.
If the system does not acquire the correct
satellite within the prescribed search
pattern, the antenna will retarget and the
cycle will repeat (Search Delay timeout,

4012 GX User Menus
The following is a complete listing of all of the menu screens and the parameter setting available on each of those screens.
Log in to the MXP from the computer. If the computer has not been set up for you by the dealer, refer to the
Installation manual for instructions. When you access the MXP you will first see the login screen:
Enter the login ID as “User” and password as “seatel3”. Both of these are case sensitive.
There are no entries that you can make on this screen. It is read only, and is periodically refreshed. The System Status
screen would also be displayed if you had clicked on the word “System”, under the “Status” menu group. There are five
groups of parameters on this screen
The System group on this display provides
Modem Rx Lock
This display can also be viewed in the header of
every menu screen.
The Front Panel LED group on this display
provides the same six indicators that are on the
front panel of the MXP
These represent the six LEDs seen on the front
panel of the MXP.
Satellite Signal Automatic Search
The ship’s position (Latitude & Longitude) and Heading are displayed in the header of every menus screen. The
Latitude & Longitude are also displayed on this screen where you view the satellite which is currently selected, or select
the satellite you want to target.
Here you can select a satellite by clicking on the drop down menu and choosing the desired satellite from this
saved/configured satellites in the drop down list.
Once a satellite is selected, targeting and inclined searching is performed automatically.
Clicking on the drop down box will allow you to see the selections.
This is the method of satellite selection that will most commonly be utilized by the users, under the “User” Log-in.
Your dealer should have set up at least one
satellite for you. If your screen is blank none
To target a desired satellite, simply select it from
You may be asked by your dealer to run a graph
for them to use for diagnostics purposes.
Select the desired graph from the dropdown list.
All graphs are driven by live data.
You have the choice of displaying live or historic
Live allows viewing & recording live information.
Historical allow the historical data to be viewed.
There are four zoom levels.
In a zoom level, live data is drawn from left to
right, within a specified time interval.
To read out a value of an event:
Count the number of divisions
Multiply the number of divisions by the unit on
Add the number labeled as the base on that axis.

For Dealer and SysAdmin an input field for CLI
(Command Line Interface) commands is
provided to change AZ, EL, CL, etc.
This is the screen that you would use to
manually locate a satellite.
These settings and commands only apply to the

Spiral (default)
The choices for Tx Polarity are
Circular polarity choices are for future use.
Select the LNB frequency band (refer to LNB
As mentioned before, the 4012 GX is s single
reflector system, so there will be no “Secondary”
selection for it.
The LNB is set to either cross pol or co-pol.
In Auto Threshold the system adds the “noise
floor” off-satellite AGC level to this Auto
Threshold value, and calculates the Threshold.
The threshold is recalculated whenever the
antenna goes into Search, or is commanded to
target a satellite. This is what is represented by
the red line on the Signal Level graph.
In Manual the Threshold level stays fixed,
regardless of the state of the antenna.
If you are in the “fringe” area of a footprint, you
may not have sufficient carrier-to-noise ratio, so
you might need to set the Threshold extremely
low, just to be able to track the desired satellite.
After you make the selections, click the Submit
button to submit it to RAM.
Note: The Submit button submits it to working
memory and “Save” submits it to the equivalent
of NVRAM.
So, if you cycle Power, these parameters will be
lost if not saved.
Contact your network service provider for the
correct settings for all of the satellites that this
system might be used on.
Configure all of the satellites and save them as
“favorites”.
The Left, Right, Up, and Down arrows give you
the ability to move the antenna in incremental
(Each key press is 0.3 degrees.)
The displayed AZ and EL represent the actual
angle of the reflector.
AZ, EL, and CL entry fields give you the ability to
submit that target command. CL should always
be left at 0.0 except when testing CL drive
These values may not match.
The left values are displays.
The right boxes are entry fields only, which do
not change unless the operator enters new
values into them.
The values displayed on the left are constantly
updated to accurately reflect the actual antenna
AZ, EL and CL Target are the last command that
the operator entered.
Turning Tracking OFF inhibits an Auto Search
pattern from beginning, or continuing.
You can turn a Search pattern on or off.
And the search pattern is determined by the
Search Pattern drop down selection.
If you have “ON” selected the antenna will go
into Auto Search.
If the antenna completes a Search Delay
timeout, and AGC is still below threshold, it will
go into a Search.
If the antenna is in the middle of a Search
Pattern, and you want to stop it, select Off.
Slow Scan changes drive to a motor.
There are certain instances where we may want
to drive the antenna extremely slowly (ie 0.2 or
0.3 degrees per second).
Slow Scan mode smooth’s out the drive so we
can really see effects of any stickiness in the
bearings or physical restrictions.
An example of when you need to drive the
antenna slowly, or at a very specific speed, is
when you are doing a side lobe test.
You would drive the antenna off in Azimuth,
then drive up at a very steady slow rate to
display the low side lobes, then main beam, then
continue to drive it off through high side lobes.
Tx Mute inhibits transmitting.
If you are in Manual Pol you will be able to enter
the value of where you want to drive the polarity
of the feed to.
The values you see in the target boxes are “last
In this example it is in Auto mode, so the entries
are grayed out and manual control is disabled.
This is similar to the AZ, EL, and CL Target, in
that you enter the desired position on the right
entry boxes, and the readout shows the actual

Stowing the Antenna
This antenna must be properly stowed if the ship will be underway while AC power to the Above Decks Equipment (ADE) is deenergized. Failure to do so may void your warranty. It is strongly recommended that AC Power to the ADE be supplied from an
adequately rated Un-interruptible Power Supply (UPS).
CAUTION: There are three Stow restraints that MUST be installed on this
antenna pedestal if the ship will be underway while the Above Decks
Equipment is de-energized.
Installing the Stow Restraints
The order in which the restraints are installed is not critical.
Installing the AZ Shipping/Stow Restraint
The AZ Shipping/Stow restraint is formed by a
pin bolt that is lowered into a channel in a
stowage block on the upper plate of the
pedestal (as shown).
Remove the pin bolt from the “STOW” hole
(this only stows the pin bolt, not the antenna).
Rotate the antenna to center the LOCK hole
directly over the stow block channel.
Pin bolt (this is the UN-Stowed position of the
Stow Block Channel
To restrain azimuth rotation of the antenna,
install the pin bolt in the “Lock” hole and
assure that the pin drops into the channel in
the stow block below.
Verify that the stow pin is engaged in the
channel of the stow block and that the
antenna does NOT rotate in Azimuth.
Installing the EL Shipping/Stow Restraint
The EL Shipping/Stow restraint is formed by a
Stow pin-bolt mounted through a bracket and
is engaged into a hole/slot in the elevation
driven sprocket when the dish is at zenith (90
degrees elevation).
In the un-stowed position the hardware from
left to right is Stow pin-bolt head, hex nut,
washer, bracket, washer, hex nut so that the
pin section of the Stow pin-bolt is NOT

driven sprocket. Using a ¾” open end wrench,
remove the hex nut and washer from the stow
pin-bolt.
Remove the stow pin-bolt from the bracket.
Remove the washer from the stow pin-bolt
and unthread the hex nut from the bolt.
Put one of the washers onto the stow pin-bolt
and insert it into the bracket toward the
elevation driven sprocket.
Put the other washer, and then thread the 2
hex nuts onto the bolt.
Tighten the hex nuts to prevent the hardware
from loosening while in the stowed
Verify that the antenna does not rotate in
Installing the CL Shipping/Stow Restraint
The CL Shipping/Stow restraint is formed by a
red locking bar with adjustable bumpers at
each end of the bar. This mechanism is
placed under the cross-level beam to lock it in
place (at level).
If not already removed, remove an adjustable
bumper, by removing the bottom nut, from
one end of the locking bar.
If not already loosened, loosen the top nut up
toward the rubber bumper.
Insert vacant end of the locking bar through
the opening under the cross-level beam.
Insert the adjustable bumper into the vacant
hole on the end of the locking bar.
To restrain the cross-level axis of the antenna
use a 7/16“ open end wrench to tighten the
nut on the top side of the locking bar until the
rubber bumper is forced up against the
bottom of the cross-level beam.
Verify that the antenna does NOT rotate (tilt
left & right from level).
Re-install and tighten the bottom nut on the
under side of the locking bar.
Removing the Shipping/Stow Restraints PRIOR to Power-Up
The order in which the restraints are removed is not critical.
CAUTION: There are three shipping/Stow restraints on this antenna pedestal
that MUST be removed, before energizing the antenna, for normal operation.
Removing the AZ Shipping/Stow Restraint
To un-stow the antenna, remove the pin bolt
from the LOCK position.
Install the pin bolt into the STOW hole and
tighten. This assures that it does not get lost
and will be ready for re-use if the antenna
needs to be stowed again at a later date.
Verify that the antenna is able to rotate freely
Removing the EL Shipping/Stow Restraint
In the stowed position the hardware from left
to right is Stow pin-bolt head, washer, bracket,
