1.7.1. Overview:
OpenAMIP, an ASCII message based protocol invented and Trademarked by iDirect is a specification for the
interchange of information between an antenna controller and a satellite modem. This protocol allows the
satellite modem to command the ACU (via TCP port 2002) to seek a particular satellite as well as allowing
exchange of information necessary to permit the modem to initiate and maintain communication via the
antenna and the satellite. In general, OpenAMIP is not intended for any purpose except to permit a modem
and the ACU to perform synchronized automatic beam switching. It is NOT a status logging system or a
diagnostic system. In addition, OpenAMIP is intend for a typical installation whereby a specific satellite
modem and Antenna system are properly configured to work together. The protocol does not make specific
provisions for auto-discovery or parameter negotiation. It is still the responsibility of the installer to assure
the parameters of both the satellite modem (proper option files) and the ACU/PCU (setup parameters) are

2. Site Survey
The objective of the Site survey is to find the best place to mount the antenna & the below decks equipment, the length and
routing of the cables and any other items or materials that are required to install the system and identify any other issues that
must be resolved before or during the installation. For Naval Engineering level information on this subject, please refer
to Antenna Installation Guideline – Site Arrangement, document number 130040_A available on the Sea Tel
Dealer Support Site.

8. For an ADE mounted greater than 0.6 meters (24 inches) above the ship’s structure, at least one (1)
foot rung should be added. Additional rungs should be added for every 0.3 meter (12 inches) of
pedestal height above the ship’s structure.
9. For an ADE mounted greater than 3 meters (9 feet) above the ship’s structure, a fully enclosing cage
should be included in way of the access ladder, starting 2.3 meters (7 feet) above the ship’s
structure.

support structure will reduce the vibration tendencies. Mounting the antenna directly above the girder
columns provides ample support to the antenna pedestal and locates the antenna weight where it will
influence the natural frequency of the mast the least.
2.8. Cables
During the site survey, walk the path that the cables will be installed along. Pay particular attention to how cables will
be installed all along the path, what obstacles will have to have be routed around, difficulties that will be encountered
and the overall length of the cables. The ADE should be installed using good electrical practice. Sea Tel recommends
referring to IEC 60092-352 for specific guidance in choosing cables and installing cables onboard a ship. Within these
guidelines, Sea Tel will provide some very general information regarding the electrical installation.
In general, all cables shall be protected from chaffing and secured to a cableway. Cable runs on open deck or down a
mast shall be in metal conduit suitable for marine use. Cables passing through bulkheads or decks shall be routed
through approved weather tight glands.
2-5
5009-17 Installation Manual Site Survey
2.9. Grounding
All metal parts of the ADE shall be grounded to bare metal at the mounting pedestal. Grounding straps from the base
of the ADE to a dedicated lug on the mounting pedestal are preferred, but grounding may also be accomplished by
exposing bare metal under all mounting bolts prior to final tightening. Preservation of the bare metal should be done
to prevent loss of ground.
Grounding should be ensured throughout the entire mounting to the hull. While it is presumed the deckhouse is
permanently bonded and grounded to the hull, in cases where the deckhouse and hull are of different materials a
check of an independent ground bonding strap should be made. Masts should be confirmed to be grounded to the
deckhouse or hull.

3. Installation
Your antenna pedestal comes completely assembled in its radome. This section contains instructions for unpacking, final
assembly and installation of the equipment. It is highly recommended that installation of the system be performed by trained
technicians.
Your antenna may have been ordered in any one of a variety of different diameter radomes. The installation instructions for
most common radome sizes for your system are below.
NOTE: Unless otherwise indicated, all nuts and bolts should be assembled with Loctite 271
or its equivalent
WARNING: Assure that all nut & bolt assemblies are tightened according to the
tightening torque values listed below:
SAE Bolt Size Inch Pounds Metric Bolt Size Kg-cm
1/4-20 75 M6 75.3
5/l6-18 132 M6 225
3/8-16 236 M12 622
1/2-13 517
WARNING: Hoisting with other than a webbed four-part sling may result in catastrophic
crushing of the radome. Refer to the specifications and drawings for the fully assembled
weight of your model Antenna/Radome and assure that equipment used to lift/hoist this
system is rated accordingly.
CAUTION: The antenna/radome assembly is very light for its size and is subject to large
swaying motions if hoisted under windy conditions. Always ensure that tag lines, attached
to the radome base frame, are attended while the antenna assembly is being hoisted to its
assigned location aboard ship.

CAUTION: Rough handling, tight bending, kinking, crushing and other careless
handling of the cables and their connectors can cause severe damage.
The cables must be routed from the above-decks equipment mounting location through the deck and
through various ship spaces to the vicinity of the below-decks equipment. When pulling the cables in place,
avoid sharp bends, kinking, and the use of excessive force. After placement, seal the deck penetration glands
and tie the cables securely in place all along the cable run(s).

wire connection to the modem to comply with FCC
Order 04-286 and WRC-03 Resolution 902.
• Dual or Quad Antenna Arbitrator coax switches in
dual antenna configurations. The coax switches
select which antenna is feeding signal to the
below decks equipment.
• Mute the Transmit output of the Satellite Modem
used in TX/RX antenna configurations when the
antenna is positioned where people may be
harmed by the transmit power emanating from
the antenna (RF Radiation Hazard).
• Mute the Transmit output of the Satellite Modem
used in TX/RX antenna configurations when the
antenna is mispointed by 0.5 degrees, or more,
and keep it muted until the antenna has been
within 0.2 degrees of peak pointing to the satellite
for a minimum of 5 seconds (FCC part 25.221 & 25.222 TX Mute requirement).

3.8. Power-Up
Verify that all shipping straps and restrains have been removed prior to energizing the antenna.
When all equipment has been installed, turn ACU Power and Antenna power ON. The ACU will initially sequentially
display:
“SEA TEL – MASTER and DAC-2202 VER 6.xx” followed by,
“SEA TEL – RCVR and SCPC VER 5.xx” followed by,
“SEA TEL – IO MOD and COMMIF VER 1.xx” followed by,
“SEA TEL – REMOTE and INITIALIZING”. After initialization, the bottom line of the remote display will display
the antenna model number and the software version from the PCU.
Energize and check the other Below Decks Equipment to verify that all the equipment is operating. You will need to
assure that the ACU is setup correctly and that the antenna acquires the correct satellite before you will be able to
completely check all the below decks equipment for proper operation.

At the ACU:
1. From the ACU - REMOTE BALANCE parameter: Enable balance mode (refer to your ACU manual).
The screen should now display “REMOTE BALANCE ON”.
At the Antenna:
2. At the Antenna: Balance the antenna with the elevation near horizon (referred to as front to back
balance) by adding, or subtracting, small counter-weights.
3. Then balance Cross Level axis (referred to as left-right balance) by moving existing counter-
weights from the left to the right or from the right to the left. Always move weight from
one location on the equipment frame to the same location on the opposite side of the equipment
frame (ie from the top left of the reflector mounting frame to the top right of the reflector
mounting frame). Do NOT add counter-weight during this step.
4. Last, balance the antenna with the elevation pointed at, or near, zenith (referred to as top to bottom
balance) by moving existing counter-weights from the top to the bottom or from the
bottom to the top. Always move weight from one location on the equipment frame to the same
location on the opposite side of the equipment frame (ie from the top left of the reflector
mounting frame to the bottom left of the reflector mounting frame). Do NOT add counter-weight
during this step.
5. When completed, the antenna will stay at any position it is pointed in for at least 5 minutes (with no
ship motion).
6. Do NOT cycle antenna power to re-Initialize the antenna. Return to the ACU, which is still in
REMOTE BALANCE mode, and press ENTER to exit Remote Balance Mode. When you exit Balance
Mode the antenna will be re-initialized, which turns DishScan, Azimuth, Elevation and Cross-Level
drive ON.

If AZ TRIM was a plus value: HFO = (TRIM / 360) x 255 Example: AZ TRIM was 0200 (plus 20 degrees).
HFO = (20/360) x 255 = (0.0556) x 255 = 14.16 round off to 14. Set, and Save, HFO to 014 using the “To
Enter the HFO value” procedure below.
If AZ TRIM was a negative value: HFO = ((360-TRIM) / 360)) x 255 Example: AZ TRIM = -0450 (minus 45
degrees). HFO = ((360 – 45) / 360)) x 255 = (315 / 360) x 255 = 0.875 x 255 = 223.125 round of to 223. Set,
and Save, HFO to 223 using the “To Enter the HFO value” procedure below.

“home” should be 90.0 Relative.
8. I now calculate the HFO = = ((90.0) / 360)) x 255 = 0.25 x 255 = 63.75 which I round off to 64.
9. I set, and Save, HFO to 222 using the “To Enter the HFO value” procedure below. After I re-initialize
the relative position of the antenna is now calibrated.
10. If there is a small amount of error remaining, I will use AZ TRIM in the Optimizing Targeting
procedure to correct it.
9-3
5009-17 Installation Manual Setup – Home Flag Offset
During initialization, azimuth drives the antenna CW until the Home Flag Switch senses the trailing edge of the metal
tab (as shown in the left picture above). The sensor will appear to go past the metal tab, then come back to the
trailing edge of the metal tab and stay there. This “home” position orients the pedestal to the “BOW” reference in the
radome which is directly forward of the entry hatch in the radome base. The Home Flag signal into the PCU “presets”
the relative position counter to the value stored in the Home Flag Offset (default value saved in the PCUs is 000).
This assures that the encoder input increments and decrements from this initialization value, therefore, does not have
to be precision aligned.
The metal Home Flag tab is mounted in a nylon clamp assembly. The nylon bolt/nut can be loosened to rotate the
clamp around underneath the power ring. (as shown in the center picture above).
In the simplest scenario, if you could rotate the antenna pedestal to be in-line with the bow and then rotate the home
flag clamp assembly around until the trailing edge is centered on the body of the home flag sensor, and tighten the
clamp HFO would be set close enough for “Optimizing Targeting” procedure to be effective. Unfortunately, rarely is
the equipment going to align where the clamp and sensor will be easy to access, reach and see, to align it this way.
The hex bolt heads in the plate below the Home Flag Clamp assembly are 60 degrees apart (as shown in the picture
on the right above) and allow multiple points of view to calibrate rotation of the clamp to.
If you installed the ADE with the “Bow” reference of the radome oriented in-line with the bow, the antenna pedestal
will be pointed in-line with the ships bow when stopped at the Home Flag position on completion of initialization
(before it targets a satellite) as shown in Figure 1 in the Electrical Calibration Procedure above. In this case, when the
antenna stops at the home flag and is pointed in-line with the Bow, Home Flag Offset (HFO) should be set to zero and
mechanical position of the metal Home Flag tab should be left at the 0° (default) position. Any small mechanical
mount error will be compensated when “Optimizing Targeting” is accomplished to correct for small variations of up to
+/- 5.0 degrees.
If the ADE is installed with the “Bow” reference of the radome oriented 45° to starboard the pedestal, when at home
flag position, will be pointed 45° CCW of the bow (at relative 315° as shown in Figure 2 in the Electrical Calibration
Procedure above). To compensate for this, loosen the home flag clamp, rotate the trailing edge of the metal home flag
tab CW 45° and tighten the clamp bolt (use caution not to tighten too much and strip the nylon hardware)..
You will have to estimate this 45° rotation based on the 60° spacing of the hex bolt centers. Re-initialize the antenna
and verify that when at home flag position it is pointed in-line with the ships bow. Do NOT change the Home Flag
Offset value saved in the PCU, small variations will be compensated for when “Optimizing Targeting” is
accomplished.
If the ADE is installed with the “Bow” reference of the radome oriented 90° to port, the pedestal when at home flag
position, will be pointed 90° CW of the bow (at relative 090° as shown in Figure 3 in the Electrical Calibration
Procedure above). To compensate for this, loosen the home flag clamp, rotate the trailing edge of the metal home flag
tab CCW 90° and tighten the clamp bolt (use caution not to tighten too much and strip the nylon hardware)..
You will have to estimate this 90° rotation based on the 60° spacing of the hex bolt centers. Re-initialize the antenna
and verify that when at home flag position it is pointed in-line with the ships bow. Do NOT change the Home Flag
Offset value saved in the PCU, small variations will be compensated for when “Optimizing Targeting” is
accomplished.

Setup – Searching 5009-17 Installation Manual

5009-17 Installation Manual Setup – Searching
You configure the ACU to use this pattern by using the following settings:
SEARCH INC - set to the default value for the frequency band that your antenna model is currently
being used for (typically 15 counts).
SEARCH LIMIT – leave this set to the default value.
SEARCH DELAY – default, or any number of seconds from 1-255 that you would prefer that the
ACU wait before starting an automatic search.
SWEEP INC – Larger antennas should have slower speeds and smaller antennas should have faster
speeds:
Larger antennas should have slower speeds set to 0047 (= 5 degrees/second) for 2.4M to
3.6M antenna systems).
Mid size antennas can be driven a little faster, set to 0063 (= 8 degrees/second) for 2M
antennas models).
Smaller antennas should have faster speeds, set to 0079 (= 18 degrees/second) for all
0.8M to 1.5M antenna models).
GYRO TYPE – MUST be set to zero for this search pattern.
SAT REF mode – MUST be ON for this search pattern.
Target any satellite longitude value which includes even tenths digit values (ie SAT 101.0 W or SAT 101.2 W).
If the desired satellite longitude includes an odd tenths digit, you must round it up, or down, one tenth to
make the tenths digit EVEN. The Antenna Control Unit calculates the Azimuth, Elevation and Polarization
values it will use to target the antenna. However, without heading input, the ACU cannot target a “true
azimuth” position (relative to true North). It will target the antenna to the calculated elevation and a
repeatable “Start” relative azimuth position. In Series 04 antennas this relative position will be 90 degrees
away from the nearest mechanical stop. In all other antennas it will be 000 degrees relative.
Initially the antenna will go to the “Start” relative azimuth position at the calculated elevation. Then the
antenna will search up 450 degrees in azimuth, search up one Search Increment in elevation, search down
450 degrees in azimuth, search down two Search Increments in elevation, etc until Search Limit is reached.
When the end of the search pattern is reached, the ACU will retarget the antenna back to the start point
shown in the graphic below.
If the desired signal is found (AND network lock is achieved in the satellite modem) at this position, or
anywhere within the search pattern, the ACU will terminate search and go into Tracking mode. If the desired
signal is not found the ACU will wait SEARCH DELAY seconds and then begin the search pattern again. This
cycle will repeat until the desired satellite signal is found or the operator intervenes.

Setup – Blockage & RF Radiation Hazard Zones 5009-17 Installation Manual
The ACU provides a contact closure to ground on the SW2 terminal of the Terminal Mounting Strip when the antenna
is pointed within any one of the blockage/hazard zones or the system is searching, targeting, unwrapping or is mis-
pointed by 0.5 degrees or more (FCC TX Mute function for Transmit/Receive systems only). The contact closure is a
transistor switch with a current sinking capability of 0.5 Amp. Refer to “Functional Testing” for instructions on how to
simulate a manual BLOCKED condition to test SW2 logic output.
When used as simple “BLOCKED” logic output for a single Sea Tel antenna, this output could be used to light a remote
LED and/or sound a buzzer to alert someone that the antenna is blocked, and therefore signal is lost.
In a “Dual Antenna” installation, this logic output is also used to control a Dual Antenna Arbitrator panel to switch the
TXIF & RXIF signals from Antenna “A” to Antenna “B” when Antenna “A” is blocked, and vice versa.
When used as simple “RF Radiation Hazard” logic output for a single Sea Tel TXRX antenna, this output could be
used to suppress RF transmissions while the antenna is pointed where people would be harmed by the transmitted
microwave RF power output. The SW2 output would be interfaced to the satellite modem to disable the TX output
signal from the Satellite TXRX Modem whenever the antenna is within the RF Radiation Hazard zone(s).
11-1
5009-17 Installation Manual Setup – Blockage & RF Radiation Hazard Zones
When used for “FCC TX Mute” logic output for a single Sea Tel TXRX antenna, this output is used to suppress RF
transmissions whenever the antenna is mis-pointed 0.5 degrees or more, is blocked, searching, targeting or
unwrapping. The SW2 output would be interfaced to the satellite modem to disable/mute the TX output signal from
the Satellite TXRX Modem. When the mute condition is due to antenna mis-pointing, it will not un-mute until the
pointing error of the antenna is within 0.2 degrees. The default output is contact closure to ground when the antenna
is mis-pointed, therefore providing a ground to “Mute” the satellite modem from the SW2 terminal of the Terminal
Mounting Strip. If your satellite modem requires an open to “Mute”, refer to SYSTEM TYPE parameter 16 value to
reverse the output logic from the ACU.
Programming instructions:
Determine the Relative AZ positions where blockage, or RF Radiation Hazard, exists. This may be done by monitoring
the received signal level and the REL display readings while the ship turns or by graphing the expected blockage
pattern. Elevation of the antenna in normal use also must be taken into consideration. A Mast or other structure may
cause blockage at low elevation angles, but may not cause blockage when the antenna is at higher elevation angles
where it is able to look over the structure. Up to four zones may be mapped. Only zones which are needed should be
mapped (in AZ LIMIT pairs).
In unlimited antenna systems the Relative position of the antenna must have been calibrated by properly setting the
Home Flag Offset (HFO) value in the PCU. The HFO calibrates Relative to display 0000 when the antenna is pointed in-
line with the bow of the boat/ship (parallel to the bow).
Convert the relative readings to AZ LIMIT/EL LIMIT values by multiplying by 10. Enter the beginning of the first
blockage region as AZ LIMIT 1 and the end of the region (clockwise direction from AZ LIMIT 1) as AZ LIMIT 2
parameters in the ACU. If needed, repeat setting AZ LIMIT 3 & 4 for a second ZONE and then AZ LIMIT 5 & 6 if a
third ZONE is needed. All unneeded zone AZ LIMIT pairs must be set to 0000. Set the upper elevation limit of each
blockage zone (also entered in degrees multiplied by 10).
EXAMPLE 1 - Three blockage Zones: A ship has a Sea
Tel antenna mounted on the port side and an Inmarsat
antenna mounted on the starboard side. A mast forward, the
Inmarsat antenna to starboard and an engine exhaust stack
aft form the three zones where satellite signal is blocked (as
shown in the graphic). In this example zone 1 is caused by
the mast, zone 2 is from the Inmarsat antenna, zone 3 is
from the stack and zone 4 is not needed:
ZONE 1 begins (AZ LIMIT 1) at 12 degrees Relative
and ends (AZ LIMIT 2) at 18 degrees Relative.
Multiply these Relative positions by 10. Enter AZ
LIMIT 1 value of 0120 and AZ LIMIT 2 value of
0180. In this case the mast height only causes
blockage up to an elevation of 50 degrees, so we
set EL LIMIT 12 to 0500. If the antenna is between
these two AZ Limit points but the elevation is
greater than 50 degrees, the antenna will no longer
be blocked.
ZONE 2 begins (AZ LIMIT 3) at 82 degrees Relative
and ends (AZ LIMIT 4) at 106 degrees Relative.
Multiply these Relative positions by 10. Enter AZ
LIMIT 3 value of 0820 and AZ LIMIT 4 value of 1060. In this case the Inmarsat antenna height only causes
blockage up to an elevation of 12 degrees, so we set EL LIMIT 34 to 0120. If the antenna is between these
two AZ Limit points but the elevation is greater than 12 degrees, the antenna will no longer be blocked.
ZONE 3 begins (AZ LIMIT 5) at 156 degrees Relative and ends (AZ LIMIT 6) at 172 degrees Relative. Multiply
these Relative positions by 10. Enter AZ LIMIT 5 value of 1560 and AZ LIMIT 6 value of 1720. In this case
the stack antenna height only causes blockage up to an elevation of 36 degrees, so we set EL LIMIT 56 to
0360. If the antenna is between these two AZ Limit points but the elevation is greater than 36 degrees, the
antenna will no longer be blocked.
ZONE 4 is not needed. Enter AZ LIMIT 7 value of 0000 and AZ LIMIT 8 value of 0000. Set EL LIMIT 78 to
0000. If your ACU software includes 5 volt polarization you will not see these AZ & EL LIMIT parameters.

EXAMPLE 3 - One blockage Zone: A ship has a Sea Tel antenna mounted on the center line of the ship. A mast is
forward and an engine exhaust stack is aft. In this example the
Stack does NOT block the satellite, only the mast forward
does. In this example zone 1 is caused by the mast, zone 2, 3
and 4 are not needed:
ZONE 1 begins (AZ LIMIT 1) at 352 degrees Relative
and ends (AZ LIMIT 2) at 8 degrees Relative. Multiply
these Relative positions by 10. Enter AZ LIMIT 1
value of 3520 and AZ LIMIT 2 value of 0080. In this
case the mast height only causes blockage up to an
elevation of 52 degrees, so we set EL LIMIT 12 to
0520. If the antenna is between these two AZ Limit
points but the elevation is greater than 52 degrees,
the antenna will no longer be blocked.
ZONE 2 is not needed. Enter AZ LIMIT 3 value of
0000 and AZ LIMIT 4 value of 0000. Set EL LIMIT 34
to 0000.
ZONE 3 is not needed. Enter AZ LIMIT 5 value of
0000 and AZ LIMIT 6 value of 0000. Set EL LIMIT 56
to 0000.
ZONE 4 is not needed. Enter AZ LIMIT 7 value of
0000 and AZ LIMIT 8 value of 0000. Set EL LIMIT 78 to 0000. If your ACU software includes 5 volt
polarization you will not see these AZ & EL LIMIT parameters.
EXAMPLE 4 - Overlaid Blockage Zones: A ship has a
Sea Tel antenna mounted on the center line of the ship. A
mast mounted on top of a deckhouse (like the picture
below) is forward and an engine exhaust stack, also on a
deckhouse, is aft. These two blockage areas have wide
azimuth blockage at lower elevations and then a narrower
azimuth area of blockage extends up to a higher value of
elevation.
ZONE 1 begins (AZ LIMIT 1) at 334 degrees
Relative and ends (AZ LIMIT 2) at 026 degrees
Relative. Multiply these Relative positions by 10.
Enter AZ LIMIT 1 value of 3340 and AZ LIMIT 2
value of 0260. In this case the mast height only
causes blockage up to an elevation of 40 degrees,
so we set EL LIMIT 12 to 0400. If the antenna is
between these two AZ Limit points but the
elevation is greater than 40 degrees, the antenna
will no longer be blocked.
ZONE 2 begins (AZ LIMIT 3) at 352 degrees
Relative and ends (AZ LIMIT 4) at 008 degrees
Relative. Multiply these Relative positions by 10.
Enter AZ LIMIT 3 value of 3520 and AZ LIMIT 4
value of 0080. In this case the mast height only
causes blockage up to an elevation of 70 degrees,
so we set EL LIMIT 34 to 0700. If the antenna is
between these two AZ Limit points but the
elevation is greater than 70 degrees, the antenna
will no longer be blocked.

To Test the blockage function:
1. Press the NEXT key until you are at the Status menu. (Sea Tel – Remote and antenna software display)
Press ENTER to access the Tracking menu.
2. Press the RIGHT arrow key to bring up and move the cursor to the far right. Press the UP arrow to simulate a
manual BLOCKED condition. BLOCKED will appear in the Tracking display.
3. Verify that SW2 terminal shorts to ground (or open circuit if you have SYSTEM TYPE configured to reverse
the output logic). If the antenna is on the desired satellite and you have RX Synch, also verify that the
Satellite Modem TX is disabled/muted (TX LED OFF).
4. Press the LEFT arrow key and then press the UP arrow key to turn the simulated blocked condition OFF.
BLOCKED will disappear, leaving the ON/OFF Tracking status and the band selection in the Tracking display.
Press the UP arrow key again if you wish to toggle the Tracking state.
5. Verify that SW2 terminal is open circuit (or ground if you have logic reversed). If the antenna is on the
desired satellite and you have RX Synch, also verify that the Satellite Modem TX is enabled (TX LED ON).
12.7. Testing the Satellite Modem Lock (Network ID) Input in the ACU
The input connections from the modem can be tested by selecting the external AGC input and monitoring the
displayed value. To test the external AGC, set the tuning frequency to 0000. Normally, AGC readings below 800 are
considered a low condition and indicate modem lock and AGC readings above 800 are considered a high condition
and indicate modem unlock.
1. Verify that the satellite modem currently has RX Sync (RX Sync LED ON).
2. Turn tracking OFF so that the antenna stays pointed ON satellite.
3. Press NEXT until the Satellite menu is displayed. Press ENTER 3 times to display the Frequency entry
window. Record the frequency that the tracking receiver is currently tuned to. Press LEFT or RIGHT arrow
key to bring up the cursor under the units digit Use the UP or DOWN arrow keys to increment or decrement
the selected digit, use the LEFT arrow key and the UP or DOWN arrow keys to change the next digit.
Continue until frequency is set to 0000. Press the ENTER key to tune the tracking receiver to this frequency.
4. View current ON satellite LOCKED AGC value in the lower right corner of the display and measure the DC
Voltage from EXT AGC (+) terminal to the GND (-) terminal. The iDirect & Comtech modems should have an
AGC readings below 800 (LOCK = low condition) and 0 VDC across the EXT AGC and GND terminals. The
Hughes modem will have an AGC reading above 800 (LOCK = high condition) and 12VDC across the EXT AGC
and GND terminals.
5. Disconnect the RXIF input coax from the rear of the satellite modem. It should lose RX Synch (RX Synch LED
OFF).
6. View current ON satellite UN-LOCKED AGC value in the lower right corner of the display and measure the
DC Voltage from EXT AGC (+) terminal to the GND (-) terminal. The iDirect & Comtech modems should have
an AGC readings above 800 (UN-LOCKED = high condition) and about +12 VDC across the EXT AGC and GND
terminals. The Hughes modem will have an AGC reading below 800 (UN-LOCKED = low condition) and
12VDC across the EXT AGC and GND terminals.
7. Reconnect the RXIF input coax to the rear of the satellite modem. It should regain RX Sync (RX Sync LED
ON).
8. Press LEFT or RIGHT arrow key to bring the up the cursor under the units digit Use the UP or DOWN arrow
keys to increment or decrement the selected digit, use the LEFT arrow key and the UP or DOWN arrow keys
to change the next digit. Continue until frequency value, recorded in step 3, is displayed and press the
ENTER key to re-tune the tracking receiver.

accurate or stable enough in some underway dynamic conditions. If there is no gyro compass or if the input is corrupt,
not stable or not consistently accurate the tracking errors will become large enough to cause the antenna to be mis-
pointed off satellite.
Satellite Reference Mode will uncouple the gyro reference from the azimuth rate sensor control loop. When operating
in Satellite Reference Mode changes in ships gyro reading will not directly affect the azimuth control loop. The
Pedestal Control Unit will stabilize the antenna based entirely on the azimuth rate sensor loop and the tracking
information from DishScan. This will keep the azimuth rate sensor position from eventually drifting away at a rate
faster than the tracking loop can correct by using the tracking errors to regulate the rate sensor bias.
Satellite Reference Mode can be used as a diagnostic mode to determine if tracking errors are caused by faulty gyro
inputs.
Satellite Reference Mode MUST be used when:
• No Gyro Compass is available
• Frequent or constant ACU Error Code 0001 (Gyro Compass has failed)
• Gyro Compass output is NMEA heading
• Flux Gate Compass is being used
• GPS Satellite Compass is being used
To view, or change, the Satellite Reference Mode status, select the SAT REF remote parameter:
1. Press the RIGHT arrow, then press the UP arrow and last press the ENTER key to turn Satellite Reference Mode
ON.
2. Press the RIGHT arrow, then press the DOWN arrow and last press the ENTER key to turn Satellite Reference
Mode OFF.

Procedure, Radome Strain Relief Installation
1.0 Purpose. To define the installation procedure for installing strain reliefs in “smooth base”
radomes.
2.0 Scope. This installation procedure applies to fiberglass radomes having Sea Tel’s standard
four-hole mounting pattern, and M12 mounting hardware, in the 80-180 cm (34-66 in)
nominal size range, typically referred to as “smooth” base radomes. It also applies to our
larger 193 cm (76-inch) radome having a twelve-hole mounting pattern. It is to be used where
the preferred center cable exit may not be desired.
3.0 Tools/materials.
1. Electric drill.
2. Small drill bit 1/8” dia. (3-4mm dia.).
3. Hole saw, 1 3/8” dia. (35 mm), with mandrel and ¼” dia. pilot drill.
4. Medium file.
5. Two 1-1/2” (38 mm) adjustable pliers.
6. #2 Phillips screwdriver.
7. Fiberglass resin & catalyst, (marine grade) - at least 2 oz (50 cc).
Such as Tap Plastics Marine Vinyl Ester Resin with MEKP Catalyst.
Note: Use liquid resin, instead of paste type, due to better penetration.
8. Mixing cup – 4 oz (100 cc).
9. Disposable brush.
10. Strain Relief Assembly 124903-1, (one per cable).
4.0 Responsibilities. It is the responsibility of the installer to observe all standard safety
precautions, including eye, slip, and chemical protection when performing this procedure.
4.1 Procedure.
