• Appropriate Coax, Ethernet, and telephone cables

1.5.

Dual Antenna Configuration

Sometimes, due to very large blockage conditions, you may need to install a dual antenna configuration to provide uninterrupted services. Two full antenna systems are installed and the ACU control outputs are connected to an arbitrator switch panel which then is connected to the below decks equipment. NOTE: The RXIF from EACH antenna

MUST be connected to the RF IN (J6) on the rear panel of its respective ACU then RFOUT (J7) is connected to the RXIF input of the Dual Antenna Arbitrator. This connection scheme is required for ACU “A” to be able to control Antenna

“A” (and ONLY Antenna “A”) AND ACU “B” to be able to control Antenna “B” (and ONLY Antenna “B”).

You will program the blockage zone(s) for each of the two antennas (refer to Setup – Blockage Zones lesson). The blockage output from the ACU is fed to the Terminal Mounting Strip so that the output of each ACU can be connected to the arbitrator panel to control it. The blockage output is available on SW2 terminal of the Terminal Mounting Strip to provide a transistor “short” to ground when the antenna is within a blockage zone programmed into the ACU. When not blocked the SW2 terminal will be an “open”.

When one antenna is blocked, its blockage output will command the arbitrator panel to switch services to the modem from that antenna to the other antenna. The arbitrator panel provides a logic latch to prevent excess switching when the ship heading is yawing, therefore, causing if the antenna to be repeatedly blocked – unblocked – blocked.

1-2

10 Series System Configuration(s) 4010W-33 Installation Manual

1.6.

Dual Antenna Arbitrator

The Dual Antenna Arbitrator panel can pass LNB voltages (and handle 250-400 ma of current) and the RXIF signals on the RX connections. TXIF, Reference and BUC supply voltage can be passed through this arbitrator panel to the antenna, but it is not recommended that BUC power be supplied through the dual channel rotary joint of the antenna

(a BUC power supply is provided on all Series 09 Antenna Pedestals).

The blockage (SW2) output, GPS output and Modem lock input from the two terminal mounting strips (antenna “A” and antenna “B”) are wired through the arbitrator panel to the satellite modem. When antenna “A” is blocked, the arbitrator PCB will toggle the coax switches so that antenna “B” provides signal to the BDE distribution (multi-switch or modem). When antenna “A” is no longer blocked the arbitrator will do nothing (because it is a latch circuit). When antenna “B” is blocked the panel will switch so that antenna “A” is again providing signal the BDE distribution.

To provide a seamless switching transition, refer to the arbitrator installation instructions to balance the TX & RX signal levels between the two antennas.

1.7.

Open Antenna-Modem Interface Protocol (OpenAMIP™) Specification:

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

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.

2.1.

Site Selection Aboard Ship

The radome assembly should be installed at a location aboard ship where:

• The antenna has a clear line-of-sight to view as much of the sky (horizon to zenith at all bearings) as is practical.

• X-Band (3cm) Navigational Radars:

• The ADE should be mounted more than 0.6 meters/2 feet from 2kW (24 km) radars

• The ADE should be mounted more than 2 meters/8 feet from 10kW (72 km) radars

• The ADE should be mounted more than 4 meters/12 feet from 160kW (250km) radars

• S-Band (10cm) Navigational Radars:

• If the ADE is/has C-Band it should be mounted more than 4 meters/12 feet from the S-band Radar.

• The ADE should not be mounted on the same plane as the ship's Radar, so that it is not directly in the Radar beam path.

• The ADE should be mounted more than 2.5 meters/8 feet from any high power MF/HF antennas (<400W).

• The ADE should be mounted more than 4 meters/12 feet from any high power MF/HF antennas (1000W).

• The ADE should also be mounted more than 4 meters/12 feet from any short range (VHF/UHF) antennae.

• The ADE should be mounted more than 2.5 meters/8 feet away from any L-band satellite antenna.

• The ADE should be mounted more than 3 meters/10 feet away from any magnetic compass installations.

• The ADE should be mounted more than 2.5 meters/8 feet away from any GPS receiver antennae.

• Another consideration for any satellite antenna mounting is multi-path signals (reflection of the satellite signal off of nearby surfaces arriving out of phase with the direct signal from the satellite) to the antenna.

This is particularly a problem for the onboard GPS, and/or the GPS based Satellite Compass.

• The Above Decks Equipment (ADE) and the Below Decks Equipment (BDE) should be positioned as close to one another as possible. This is necessary to reduce the losses associated with long cable runs.

• This mounting platform must also be robust enough to withstand the forces exerted by full rated wind load on the radome.

• The mounting location is robust enough that it will not flex or sway in ships motion and be sufficiently well re-enforced to prevent flex and vibration forces from being exerted on the antenna and radome.

• If the radome is to be mounted on a raised pedestal, it MUST have adequate size, wall thickness and gussets to prevent flexing or swaying in ships motion. In simple terms it must be robust.

If these conditions cannot be entirely satisfied, the site selection will inevitably be a “best” compromise between the various considerations.

2.2.

Antenna Shadowing (Blockage) and RF Interference

At the transmission frequencies of C and Ku band satellite antenna systems, any substantial structures in the way of the beam path will cause significant degradation of the signal. Care should be taken to locate the ADE so that the ADE has direct line-of-sight with the satellite without any structures in the beam path through the full 360 degree ships turn. Wire rope stays, lifelines, small diameter handrails and other accessories may pass through the beam path in limited numbers; however, even these relatively insignificant shadows can produce measurable signal loss at these frequencies.

Mounting Foundation

Site Survey

2.3.1.

Mounting on Deck or Deckhouse

While mounting the ADE on a mast is a common solution to elevate the ADE far enough above the various obstructions which create signal blockages, sometimes the best mounting position is on a deck or deckhouse top. These installations are inherently stiffer than a mast installation, if for no other reason than the design of the deck/deckhouse structure is prescribed by the ship’s classification society. In the deck/deckhouse design rules, the minimum plating and stiffener guidelines are chosen to preclude high local vibration amplitudes.

Most installations onto a deck or deckhouse structure will require a mounting pedestal to raise the ADE above the deck for radome hatch access and to allow the full range of elevation (see ADE mounting considerations above). Some care must be taken to ensure the mounting pedestal is properly aligned with the stiffeners under the deck plating.

2.3.2.

ADE Mounting Considerations

Mounting the radome directly on the deck, or platform prevents access to the hatch in the base of the radome unless an opening is designed into the mounting surface to allow such entry. If there is no access to the hatch the only way to service the antenna is to remove the radome top.

Two people are required to take the top off of the radome without cracking or losing control of it, but even with two people a gust of wind may cause them to lose control and the radome top may be catastrophically damaged (see repair information in the radome specifications).

If access to the hatch cannot be provided in the mounting surface, provide a short ADE support pedestal to mount the

ADE on which is tall enough to allow access into the radome via the hatch.

Ladder rungs must be provided on all mounting stanchions greater than 3-4 feet tall to allow footing for personnel safety when entering the hatch of the radome.

The recommended cable passage in the 50, 60 and 66 inch radomes is through the bottom center of the radome base, down through the ADE support pedestal, through the deck and into the interior of the ship.

2.3.3.

Sizing of the support pedestal

The following should be taken into account when choosing the height of a mounting support stand:

1.

The height of the pedestal should be kept as short as possible, taking into account recommendations given in other Sea Tel Guidelines.

2.

The minimum height of the pedestal above a flat deck or platform to allow access into the radome for maintenance should be 0.6 meters (24 inches).

3.

The connection of the ADE mounting plate to the stanchion and the connection of the pedestal to the ship should be properly braced with triangular gussets (see graphic above). Care should be taken to align the pedestal gussets to the ship’s stiffeners as much as possible. Doublers or other reinforcing plates should be considered to distribute the forces when under-deck stiffeners are inadequate.

4.

The diameter of the pedestal stanchion shall not be smaller than 100 millimeters (4 inches). Where the ADE base diameter exceeds 1.5 meters (60 inches), additional stanchions (quantity greater than

3) should be placed rather than a single large stanchion.

5.

Shear and bending should be taken into account in sizing the ADE mounting plate and associated gussets.

6.

Shear and bending must be taken into account when sizing the pedestal to ship connection.

7.

All welding should be full penetration welds –V-groove welds with additional fillet welds – with throats equivalent to the thickness of the thinnest base material.

2-2

Site Survey 4010W-33 Installation Manual

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.

2.4.

Mounting Height

The higher up you mount the antenna above the pivot point of the ship the higher the tangential acceleration (gforce) exerted on the antenna will be (see chart below).

When the g-force exerted on the antenna is light, antenna stabilization and overall performance will not be affected.

If the g-force exerted on the antenna is high enough (> 1 G), antenna stabilization and overall performance will be affected.

If the g-force exerted on the antenna is excessive (1-2 Gs), the antenna will not maintain stabilization and may even be physically damaged by the g-force.

2.5.

Mast Configurations

Sea Tel recommends the ADE be mounted on the ship in a location which has both a clear line-of-sight to the target satellites in all potential azimuth/elevation ranges and sufficient support against vibration excitement. If possible, mounting the ADE pedestal directly to ship deckhouse structures or other box stiffened structures is preferred.

However, in many cases, this imposes limits on the clear line-of-sight the antenna system has.

Often the solution for providing the full azimuth/elevation range the antenna needs is to mount the ADE on the ship’s mast. Unfortunately, masts do not consider equipment masses in design and often have harmonic frequencies of their own.

There are many designs of masts used on ships – masts are nearly as unique in design as the ship is – but the designs often fall into just a few categories. These categories can be addressed in terms of typical responses and problems with regards to vibration and mounting of ADE. The most common categories of masts are:

2-3

4010W-33 Installation Manual Site Survey

2.5.1.

Vertical Masts

Vertical masts are a very ancient and common mast design. In essence, it is the mast derived from the sailing mast, adapted for mounting the ever-increasing array of antennae ships need to communicate with the world. This drawing of a Vertical mast shows preferred mounting of the ADE center-line above the plane of the radar, or as an alternate with the

ADE mounted below the plane of the radar signal, as reasonably good installations of a satellite antenna ADE.

Vertical masts are most commonly still found on cargo ships – they are simple, inelegant and functional. They are also fairly stiff against torsional reaction and lateral vibrations, as long as the ADE is mounted on a stiff pedestal near the vertical centerline of the mast. If centerline mounting is impractical or otherwise prohibited, the mast platform the ADE is mounted on should be checked for torsional vibration about the centerline of the mast and the orthogonal centerline of the platform.

If the estimated natural frequency of the mast or platform is less than 35 Hertz, the mast or platform should be stiffened by the addition of deeper gussets under the platform or behind the mast.

2.5.2.

Raked Masts

Raked masts are found on vessels where the style or appearance of the entire vessel is important.

Again, the inclined mast is a direct descendant from the masts of sailing ships – as ship owners wanted their vessels to look more unique and less utilitarian, they ‘raked’ the masts aft to make the vessel appear capable of speed. This drawing shows a raked mast, again with the preferred ADE mounting above the radar and alternate with the

ADE below the radar.

Raked masts pose special problems in both evaluating the mast for stiffness and mounting of antennae. As can be seen in the drawing all antennae must be mounted on platforms or other horizontal structures in order to maintain the vertical orientation of the antenna centerline. This implies a secondary member which has a different natural frequency than the raked mast natural frequency. In order to reduce the mass of these platforms, they tend to be less stiff than the main box structure of the raked mast. Thus, they will have lower natural frequencies than the raked mast itself. Unfortunately, the vibratory forces will act through the stiff structure of the raked mast and excite these lighter platforms, to the detriment of the antenna.

2.5.3.

Girder Masts

Girder masts are large platforms atop a pair of columns. Just like girder constructions in buildings, they are relatively stiff athwart ship – in their primary axis – but less stiff longitudinally and torsionally. An example of a girder mast is shown in this drawing, with the preferred ADE mounting outboard and above the radar directly on one of the columns and alternate with the ADE centered on the girder above the plane of the radar.

The greatest weakness of girder masts is in torsion – where the girder beam twists about its vertical centerline axis. As with all mast designs discussed so far, mounting the antenna in line with the vertical

2-4

Site Survey 4010W-33 Installation Manual 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.

2.5.4.

Truss Mast

Truss masts are a variant on the girder mast concept. Rather than a pair of columns supporting a girder beam, the construction is a framework of tubular members supporting a platform on which the antennae and other equipment is mounted. A typical truss mast is shown in this photograph.

Like a girder mast, truss masts are especially stiff in the athwart ship direction. Unlike a girder mast, the truss can be made to be nearly as stiff in the longitudinal direction. Truss masts are particularly difficult to estimate the natural frequency – since a correct modeling includes both the truss structure of the supports and the plate/diaphragm structure of the platform. In general, though, the following guidelines apply when determining the adequate support for mounting an antenna on a truss mast:

1.

Antenna ADE pedestal gussets should align with platform stiffeners which are at least

200 millimeters in depth and 10 millimeters in thickness.

2.

When possible, the antenna ADE pedestal column should align with a vertical truss support.

3.

For every 100 Kilograms of ADE weight over 250 Kilograms, the depth of the platform stiffeners should be increased by 50 millimeters and thickness by 2 millimeters.

Sea Tel does not have a recommended arrangement for a truss mast – the variability of truss mast designs means that each installation needs to be evaluated separately.

2.6.

Safe Access to the ADE

Safe access to the ADE should be provided. Provisions of the ship’s Safety Management System with regard to men aloft should be reviewed and agreed with all personnel prior to the installation. Installations greater than 3 meters above the deck (or where the access starts at a deck less than 1 meter in width) without cages around the access ladder shall be provided with means to latch a safety harness to a fixed horizontal bar or ring.

The access hatch for the ADE shall be oriented aft, or inboard, when practicable. In any case, the orientation of the

ADE access hatch shall comply with the SMS guidelines onboard the ship. Nets and other safety rigging under the ADE during servicing should be rigged to catch falling tools, components or fasteners.

2.7.

Below Decks Equipment Location

The Antenna Control Unit, Terminal Mounting Strip and Base Modem Panel are all standard 19” rack mount, therefore, preferred installation of these items would be in such a rack. The ACU mounts from the front of the rack. The

Terminal Mounting Strip and Base Modem Panel mount on the rear of the rack.

The Satellite Modem, router, VIOP adapter(s), telephone equipment, fax machine, computers and any other associated equipment should also be properly mounted for shipboard use.

Plans to allow access to the rear of the should be considered.

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

4010W-33 Installation Manual Site Survey

2.8.1.

ADE/BDE Coaxial Cables

The first concern about the coaxial cables installed between the ADE & BDE is length. This length is used to determine the loss of the various possible coax, Heliax or fiber-optic cables that might be used. You should always provide the lowest loss cables to provide the strongest signal level into the satellite modem.

Signal cable shall be continuous from the connection within the ADE radome, through the structure of the ship to the BDE. Splices, adapters or dummy connections will degrade the signal level and are discouraged.

Be careful of sharp bends that kink and damage the cable. Use a proper tubing bender for Heliax bends.

Penetrations in watertight bulkheads are very expensive, single cable, welded penetrations that must be pressure tested.

Always use good quality connectors that are designed to fit properly on the cables you are using. Poor quality connectors have higher loss, can allow noise into the cable , are easily damaged or fail prematurely.

In as much as is possible, don’t lay the coaxes on power cables. Try to have some separation from Inmarsat &

GPS cables that are also passing L-band frequencies or Radar cables that may inject pulse repetition noise –as error bits - into your cables.

2.8.2.

Antenna Power Cable

Be cautious of length of the run, for voltage loss issues, and assure that the gauge of the wires is adequate for the current that is expected to be drawn (plus margin) . Antenna power is not required to be from a UPS

(same one that supplies power to the below decks equipment), but it is recommended.

2.8.3.

Air Conditioner Power Cable

If your system includes a marine air conditioner (available with the 81 inch radome ONLY), run an AC power cable to it from a breaker, preferably from a different phase of the electrical system than supplies power to the ADE & BDE. Be EXTREMELY cautious of length of the run for voltage loss and gauge of the wires for the current that is expected to be drawn.

2.8.4.

ACU Power Cable/outlet

The AC power for the ACU and other below decks equipment is not required to be from a UPS (same one that supplies power to the ADE), but it is recommended.

2.8.5.

Gyro Compass Cable

Use good quality shielded cable (twisted pairs, individually foil wrapped, outer foil with braid overall is best)

You only need 2-wire for NMEA signal, 4-wire for Step-By-Step and 5-wire for Synchro … always use shielded cable. Be cautious of length and gauge of the run for voltage loss issues.

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.

3.3.

Installing the ADE

The antenna pedestal is shipped completely assembled in its radome. Please refer to the entire Site Survey chapter of this manual.

Base Hatch Access - Mounting the radome directly on the deck, or platform prevents access to the hatch in the base of the radome unless an opening is designed into the mounting surface to allow such entry. If there is no access to the hatch the only way to service the antenna is to remove the radome top. Two people are required to take the top off of the radome without cracking or losing control of it, but even with two people a gust of wind may cause them to lose control and the radome top may be catastrophically damaged (see repair information in the radome specifications) or lost.

If access to the hatch cannot be provided in the mounting surface, provide a short ADE mounting stanchion to mount the ADE on which is tall enough to allow access into the radome via the hatch.

Ladder rungs must be provided on all mounting stanchions greater than 3-4 feet tall to allow footing for personnel safety when entering the hatch of the radome.

Cable Passage - The radome base is designed with a bottom center cable passage and Roxtec® Multidiameter® blocks for cable strain relief. The recommended cable passage in the 50, 60 and 66 inch radomes is through the bottom center of the radome base, down through the ADE mounting stanchion, through the deck and into the interior of the ship.

Bottom center cable passage is recommended, however, a strain relief kit is provided with the system if off-center cable entry is required. Note: Strain relief installation procedure, provided in the Drawings chapter, MUST be followed to assure that the cored holes are properly sealed to prevent moisture absorption and de-

lamination of the radome base.

3.3.1.

Prepare the 50”, 60”, 66” or 76” Radome Assembly

1.

Remove the side walls of the Radome crate.

2.

Lift the pallet using a forklift and/or jacks.

3.

From the under side of the pallet, remove the

4 shipping bolts which attach the ADE to its’ pallet. Discard this shipping hardware.

4.

Remove four equally spaced bolts around the radome flange. Save these nuts and bolts to be re-installed later.

5.

Install four lifting eyebolts in the vacant holes in the flange of the radome.. (Hardware provided in the radome installation kit). Keep the original perimeter bolt hardware to be reinstalled after the ADE has been installed.

3-2

Installation

6.

Attach shackles and four part web lifting sling arrangement to the eyebolts.

7.

2.

Hoist the antenna assembly off the shipping pallet, by means of a suitably sized crane or derrick, to allow access to bottom of radome assembly.

3.

Open the hatch by pressing the round release button in the center of the black latches and gently push the hatch up into the radome. Place the hatch door (gel coat surface up) inside the radome on the far side of the antenna pedestal.

4.

Inspect the pedestal assembly and reflector for signs of shipping damage.

5.

Peel the paper off of the mounting pad (provided in the radome installation kit) to expose the sticky side of the pad, align it to the mounting holes and press it in place on the underside of the radome base.

6.

Using Loctite 271, install the 4 mounting bolts

(provided in radome mounting kit) into the radome base.

3-3


7.

Remove the hardware in the cable mounting frame.

Installation

8.

Lift the cable mounting frame out from the cable passage channel.

NOTE: If the bottom center cable passage will NOT be used, it is recommended that the strain reliefs be installed in place of this cable mounting frame. Other locations around the radome base are MUCH thicker, requiring longer strain reliefs than the ones provided by Sea Tel. Refer to the strain relief installation procedure provided in the Drawings chapter of this

manual.

9.

Man the tag line and have the crane continue lifting the ADE up and hover above the mounting site on the ship.

10.

Carefully route AC Power and IF coax cables through the cable passage in the bottom center of the radome base and through the cable channel under the lower base plate of antenna.

NOTE: Suitable strain relief should be provided below the mounting surface to prevent the cables from being kinked where the cables exit the bottom of the

radome.

11.

Allow enough service loop to terminate these cables to the circuit breaker assembly and connector bracket respectively (see cable termination information below).

HINT: It may be easier to connect, or tie-wrap, the coaxes and power cable temporarily.

12.

Lower radome assembly into the mounting holes, positioned with the BOW reference of the radome as close to parallel with centerline of the ship as possible (any variation from actual alignment can be electrically calibrated if needed).

13.

Using Loctite 271, install the 4 fender washers and hex nuts (provided in the radome installation kit), from the underside of the mounting surface, to affix the radome to the mounting surface. .

14.

Remove the clamp bar and Roxtec® Multidiameter® blocks from their cable mounting frame in the cable passage channel.

15.

Remove the rubber bar from the top of the Roxtec®

Multidiameter® blocks.

16.

Remove the Roxtec® Multidiameter® blocks from the cable mounting frame.

17.

Pass the coaxes and power cable through the cable mounting frame.

HINT: Again, It may be easier to connect, or tie-wrap, the coaxes and power cable temporarily.

18.

Re-install the cable mounting frame onto cable passage channel using the four screws and flat washers that were removed in step 7 above. .

19.

Peel layers out of the upper and lower Roxtec®

Multidiameter® blocks to provide an opening in the block that is just smaller than the outer diameter of the cable that will pass through it. When compressed the block should provide clamping force on the cable and prevent it from moving in the block.

20.

Two cables may be passed through each of the

Roxtec® Multidiameter® CM-20w40 blocks provided.

21.

If cables larger than 1.65cm/0.65in outer diameter will be used, larger single-cable Roxtec®

Multidiameter CM-40 10-32 blocks are available to allow three cables of up to3.25cm/1.28in diameter to be used. The rubber bar and the three double-

cable Roxtec® Multidiameter blocks will be

replaced by the three larger Roxtec®

Multidiameter blocks.

3-5


HINT: It may be helpful to put the clamp bar and rubber bar in place (held loosely by one screw) to hold some of the Roxtec® Multidiameter blocks in

place while you complete the others.

22.

Re-install the clamp bar using the hardware removed in step 14 above.

3.7.7.1.

Jumper Selection

JP1 – JP4 are to couple in pull-up resistors for the below listed functions. JP5 selects the DC voltage output on TS4.

JP1 SW1 – This output would be used for below decks band select - to control a band selection switch or tone generator. Default is OPEN.

JP2 SW2 (blockage & RF radiation hazard output) - Used to control dual antenna arbitrator, in dual antenna configurations, and provide TX Mute control to the Satellite Modem. Default is

SHORTED when blocked.

JP3 SW3 (reserved) - Reserved for future use.

JP4 AGC (external AGC input) - Pull-up for external AGC input from Satellite Modem which is used to a positive satellite Network ID when the modem is on the correct network (therefore the antenna is on the correct satellite). Default is SHORTED. NOTE: This jumper MUST be removed when using iDirect 3000 & 5000 Series modems.

JP5 Voltage Output Select - Select 12VDC or 24VDC. Default is 12VDC.

3.7.7.2.

J1 “Modem Console Port” connector

FCC compliance connection to an iDirect Satellite Modem can be made very easily by connecting a

Straight Serial RJ-45 cable from the J1 “Modem Console Port” connector on the Terminal Mounting

Strip to the Console port on the iDirect Modem. Your modem must be set

If your modem is Open AMIP compatible and you wish to use it in an Open AMIP configuration you will use an Ethernet patch or cross-over cable as is appropriate to connect to your LAN.

Refer to the Setup – Modem Connections, Setup and Test chapter for more information.

3.7.7.3.

TS1 Control Interface Connections.

AGC & GND - External AGC, or Modem Lock, input.

• External AGC input to the DAC-2202 must be 0 to 15 Volts DC analog signal, positive going voltage proportional to satellite signal input level and must be real-time in its response to antenna pointing.

• External Modem Lock from a satellite modem is used as a positive ID that the antenna is on the desired satellite. This input is NOT used for Tracking purposes, it is only used for satellite identification to acquire the correct satellite during search. To enable the external modem input you must include a 2 in the SYSTEM TYPE parameter (If your system type is presently 76 or 77, then change it to 78 or 79) and NID MUST be set to 0000.

• Connections - The modem lock signal connects to EXT AGC and a ground reference from the modem. The expected signal from the modem allows 0VDC to +15VDC. Low voltage indicates modem lock, high voltage indicates modem unlock.

• Testing - The input connections from the modem can be tested by selecting the external

AGC input and monitoring the displayed value. To select external AGC, set the tuning frequency to 0000. Normally, AGC readings below 2048 are considered a low condition and indicate modem lock and AGC readings above 2048 are considered a high condition and indicate modem unlock.

[If you find the AGC reading for locked and unlocked conditions need to be reversed you

must add 128 to your current SYSTEM TYPE parameter].

Turn tracking OFF when checking the external AGC inputs. Be sure to properly retune the receiver frequency when you are finished testing the external input.

• Operation - In NORMAL operation, AGC must be above Threshold AND external MODEM

Lock input must be locked to Track the satellite. If you are tracking a satellite signal and the

AGC is above threshold (Tracking light on solid) but the external AGC signal rises above 2.5

Installation 4010W-33 Installation Manual volts for more than 20 seconds (external MODEM input UNLOCKED) the ACU will automatically retarget the selected satellite.

SW1 - Band Selection control output. This output is used to control below decks tone generator(s), or coax switch(s), for band selection functions. The band selection control output is driven by the band selected in the MODE – TRACKING display.

SW2 - The Blockage/TX Mute Control output is driven by Blockage and RF Radiation Hazard functions. This output will short to ground whenever the antenna is within the programmed AZ LIMIT zone(s) or is Searching,

Targeting or is mispointed 0.5 degrees from satellite peak.

This output is commonly used to drive:

If your modem cannot use the Modem Console

Port connection you will have to provide a transmit inhibit output from the ACU by connecting a SW2 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).

3.7.7.4.

TS2 Synchro Gyro Compass Input.

Use the R1, R2, S1,S2 and S3 screw terminals to connect the Synchro Gyro Compass to the ACU.

3.7.7.5.

TS3 Step-By-Step (SBS) Gyrocompass Input.

Use the COM, A, B and C screw terminals to connect the SBS Gyrocompass to the ACU. Some SBS

Gyro distribution boxes have terminals which are labeled S1, S2 & S3 instead of A, B and C.

3.7.7.6.

TS4 Power

• VREG Screw terminal is used to provide a regulated DC operating voltage to ancillary equipment. Voltage out is dependant upon which terminal mounting strip assembly is provided. 126865-1 supplies 8Vdc @ 1Amp, while the 126865-2 assembly supplies 5Vdc

@ 2Amps.

• GND Screw terminal is the ground reference for the regulated and unregulated power terminals.

• 12/24 Screw terminal is commonly used to provide operating voltage to a external GPS,

Dual Antenna Arbitrator or other below decks tone generators or switches. Voltage output is based on the T.M.S assemblies JP5 jumper settings.

3.7.7.7.

TS5 NMEA A/B, GPS output.

• RxA- and RxA+- screw terminals, which are defined as the NMEA A connection is used to connect to the ships Gyro Compass (Heading). The

NMEA0183 compliant inputs are then connected via a 9 pin ribbon cable to the ACU’s J2 NMEA communications port. A GPS (Latitude and

Longitude) input may also be connected, but is not required because there is a GPS device already installed in your antenna.. NOTE: If you connect a ships GPS to the terminal mounting strip, you

MUST disconnect the GPS antenna on the antenna pedestal.

• RxB- and RxB+ screw terminals, which are defined as the NMEA B connection is used to connect to the ships Gyro Compass (Heading). The

NMEA0183 compliant inputs are then connected via a 9 pin ribbon cable to the ACU’s J2 NMEA communications port. A GPS (Latitude and

Longitude) input may also be connected, but is not required because there is a GPS device already installed in your antenna.

• TxA- screw terminal is used to provide a Pseudo GPS (GGA and GLL formats) output to other system components such as a Satellite Modem.

Antenna Maintenance

3.10.1.

Balancing the Antenna

The antenna and equipment frame are balanced at the factory however, after disassembly for shipping or maintenance, balance adjustment may be necessary. The elevation and cross-level motors have a brake mechanism built into them, therefore, power must be ON to release the brakes and DishScan and antenna

drive must be OFF to balance the antenna. . Do NOT remove any of the drive belts. Balancing is accomplished by adding or removing balance trim weights at strategic locations to keep the antenna from falling forward/backward or side to side. The antenna system is not pendulous so 'balanced' is defined as the antenna remaining at rest when left in any position.

The “REMOTE BALANCE” parameter (located at the end of the Remote Parameters after REMOTE TILT) of the

ACU. When enabled, Remote Balance Mode temporarily turns DishScan, Azimuth, Elevation and Cross-Level drive OFF. This function is required when trying to balance antenna systems that have a built-in brakes on the elevation and cross-level motors.

Assure that Antenna power is ON and that the antenna has completed initialization.

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.

3.10.2.

Fine Balance and Monitoring Motor Drive Torque

The DacRemP DISPTC graph chart provides a means for monitoring torque commands required for each motor for diagnostic purposes and verifying antenna balance. By observing each trace, the required drive of the antenna via the motor driver PCB may be established.

• To view the Torque Commands, select the graph chart.

• This chart displays the Torque Command errors for each axis via three traces, CL (Cross Level), LV

(Elevation), and AZ (Azimuth), at a fixed 0.195amps/vertical division.

3-15


• A normal trace display will be ± 1 divisions from the red reference line while under calm sea conditions and with DishScan Drive turned off. See example below

• The Cross Level display will decrease (plots below red line) as the antenna requires drive to the left and increase (plots above red line) as the antenna requires to the right.

Example: The antenna pictured in the screen capture below is imbalanced so that it is “Right Heavy”.

The CL trace is plotting above the red reference line (indicating that drive CCW is required to maintain a 90°Cross-Level position).

• The Level display should decrease (plots below red line) as the antenna requires drive forward (Up in elevation) and increase (plots above red line) as the antenna requires drive back (Down in elevation).

• Example: The antenna pictured in the screen capture below is imbalanced so that it is “Front Heavy”.

The LV trace is plotting above the red line (indicating that drive CW is required to maintain the current elevation position).

3-16


• The Azimuth display should decrease (plots below red line) as the antenna is driven CCW and increase (plots above red line) as the antenna is rotated CW.

Latitude and Longitude should automatically update when the GPS engine mounted on the antenna pedestal triangulates an accurate location, but you may enter this information manually to begin. Except when integrating NMEA-0183 Gyro source, you will have to enter the initial Heading of the ship, subsequently the ACU will then increment/decrement as the Gyro Compass updates.

Next, set the Satellite information. Longitude of the desired satellite you wish to use and the receiver settings for it are especially important.

At this point you should be able to target the desired satellite. Continue with the setup steps below to optimize the parameters for your installation.

Setup – Ships Gyro Compass 4010W-33 Installation Manual

5.

Setup – Ships Gyro Compass

The Ships Gyro Compass connection provides true heading (heading of the ship relative to true North) input to the system. This allows the ACU to target the antenna to a “true” Azimuth position to acquire any desired satellite.

After targeting this input keeps the antenna stabilized in Azimuth (keeps it pointed at the targeted satellite Azimuth). In normal operation when viewing and ADMC recording in DacRemP, the “Relative Azimuth” trace should do exactly equal & opposite to whatever the Heading trace does and the “Azimuth” trace should stay flat.

In normal operation the heading display in the ACU should at all times be the same value as the reading on the Gyro Compass itself (this is also referred to as Gyro Following.).

If the ACU is not Following the Ships Gyro Compass correctly (un-erringly) refer to the Troubleshooting Gyro Compass

Problems.

5.1.

GYRO TYPE

The GYRO TYPE parameter selects the type of gyro compass interface signal, the appropriate hardware connections and the ratio of the expected input signal for ship turning compensation. Default GYRO TYPE parameter for all systems is 0002 so that the ACU will properly follow for Step-By-Step or NMEA gyro signals.

If the Ships Gyro Compass output is Synchro, or there is NO Gyro Compass, the GYRO TYPE parameter must be set correctly to properly read and follow the Ships Gyro Compass signal that is being provided. The acceptable settings are:

362

90 for 360:1 Synchro with S/D Converter for 90:1 Synchro with S/D Converter

36

2

1

0 for 36:1 Synchro with S/D Converter for Step-By-Step gyro or NMEA gyro for 1:1 Synchro with S/D Converter for No Gyro linear AZ Search Mode (No Heading input available)

5.2.

Updating the GYRO TYPE parameter

To manually update, press the LEFT arrow key to bring the cursor under the least significant character. Continue to move the cursor until the desired character to be edited is underscored (selected). Use the UP or DOWN arrow keys to increment or decrement the selected character.

Use the LEFT or RIGHT arrow key to move the cursor left or right to select other characters to modify. When you are finished modifying press ENTER to execute the new value OR press NEXT to abort and exit setup mode.

When you are finished making parameter changes, go to the SAVE NEW PARAMETERS display to save the changes you have made.

5.3.

If There is NO Ships Gyro Compass

Without heading input to the system the ACU will NOT be able to target, or stay stabilized ON, a “true” azimuth pointing angle. This will make satellite acquisition much more difficult and the true azimuth value that any given satellite should be at will not be displayed correctly.

This mode of operation is NOT recommended for ships. A better solution would be to provide a Satellite

Compass (multiple GPS Antenna device) to provide true heading input to the ACU. These devices are readily available and are much less expensive than a Gyro Compass.

If there is NO Gyro Compass (ie on a large stationary rig which is anchored to the ocean floor) set the GYRO TYPE parameter to 0000, the SWEEP INC parameter to 0047 and SAT REF (Satellite Reference Mode) MUST be turned ON.

This combination of settings will cause “No Gyro” Search pattern to be use to find the desired satellite (refer to the setup – Searching lesson).

Determining the IF Tracking Frequency (MHz)

The IF Tracking frequency parameter is a value entered into the ACU’s MHZ Sub-Menu. The value itself may be provided by your air-time provider and the MHz value will be entered directly in this sub-menu.

Or, the RF downlink frequency of a specific carrier on the desired satellite can be obtained from a satellite website and calculated by using the formula RF- LO = IF. When you take the Satellite Transponder Downlink RF value and subtract the LNB’s Local Oscillator (LO) Value, the resultant value will equal the Intermediate Frequency (IF). It is this IF value that will be entered into the ACU for tracking purposes.

Example assuming an LNB LO value of 11.25GHz: 12268.0 MHz – 11250.0 MHz = 1018.0 MHz IF

KHz

The KHz rate entered into the ACU is an absolute value which also may have been provided by your air-time provider, or have been calculated, and is entered directly in this sub-menu window.

In the example above, 1018.0 MHz was calculated (1018 MHz 000 KHz) therefore, the KHz entry would be 000. If the provided/calculated value had been 1018.250, 1018 would have been entered in the MHz window and 250 would be entered in the KHz window.

Setup – Band Selection 4010W-33 Installation Manual

7.

Setup – Band Selection

To properly control the band selection of the LNB(s) mounted on the antenna the TRACK DISP (Tracking Display) parameter

must be set correctly. Which value the TRACK DISP parameter is set to depends on the hardware configuration of the antenna pedestal.

The xx09-17 and xx09-33 antenna pedestals come with the waveguide diplexer and LNB to provide the additional Co-Pol RXIF output to the Cross-Pol/Co-Pol select coax switch (all of the systems come with the switch and coax installed, so you can easily upgrade the antenna with the Co-Pol hardware).

The TRACK DISP parameter controls Tone, Voltage and Aux functions remotely on the antenna pedestal. Voltage and Tone are used to select the desired band of dual-band, tri-band and quad-band LNBs. The Aux function controls the Cross-Pol/Co-Pol select switch.

Sea Tel provides quad-band LNBs as a default LNBs on the 09 Series antennas, therefore, the default TRACK DISP parameter for

Cross-Pol only systems is 0170 and 0130 for 09 antennas with Cross-Pol AND Co-Pol LNBs.

Setup – Targeting 4010W-33 Installation Manual

8.

Setup – Targeting

In this lesson you will learn how to optimize the targeting of the antenna to land on or near a desired satellite (within +/-1 degree).

8.1.

AUTO TRIM

The Auto Trim function will automatically calculate and set the required Azimuth and Elevation trim offset parameters required to properly calibrate the antennas display to the mechanical angle of the antenna itself, while peaked ON satellite.

Refer to “Optimizing Targeting” in the Setup section of this manual for further details on the parameters settings.

To enable this function, the Antenna MUST be actively tracking the satellite with positive SAT ID and elevation of the antenna must be less than 83 degrees and the ACU must NOT be set for Inclined Orbit Search. After locating the satellite, with Tracking ON, wait at least 30 seconds before performing the AUTO TRIM feature, this will allow sufficient time for the antenna to peak up on signal. It is equally important that you verify that the system is tracking the

CORRECT satellite (verify video is produced on the Televisions in a TVRO system or verify a RX lock indication on the satellite modem in a VSAT system).

While in the AUTO TRIM sub-menu, press the LEFT arrow key to bring start the calibration procedure, the display should read AUTO TRIM SETUP, press the ENTER key to submit. AUTO TRIM SAVED will be displayed, indicating the proper AZ and EL trims were submitted to RAM. This does not save these parameters to NVRAM, in order to save to memory, continue down through the setup mode parameters until the SETUP SAVE NEW PARAMETERS sub menu is displayed. Press the RIGHT arrow and then press the ENTER key. The display should now report that the parameters were saved. From the AUTO TRIM SETUP screen, press the NEXT key (DAC2202) without hitting ENTER to escape this screen without submitting the new AZ and EL Trim values.

NOTE: AUTO TRIM LOCKED will be displayed on the front panel, indicating that the AUTO TRIM Feature is NOT allowed if all of these conditions are not met:

The ACU must be actively tracking a satellite (AGC above threshold) and

The ACU must have positive SAT ID (internal NID match or external RX lock received from the Satellite

Modem) and

The elevation angle of the antenna must be LESS than 75 degrees and

The ACU must NOT be set for Inclined Orbit Search.

8.2.

Manually Optimizing Targeting

First, assure that all of your Ship & Satellite settings in the ACU are correct.

1.

Target the desired satellite, immediately turn Tracking OFF, and record the Azimuth and Elevation positions in the “ANTENNA“ display of the ACU (these are the Calculated positions).

2.

Turn Tracking ON, allow the antenna to “Search” for the targeted satellite and assure that it has acquired (and peaks up on) the satellite that you targeted.

3.

Allow several minutes for the antenna to “peak” on the signal, and then record the Azimuth and Elevation positions while peaked on satellite (these are the Peak positions). Again, assure that it has acquired the satellite that you targeted!

4.

Subtract the Peak Positions from the Calculated Positions to determine the amount of Trim which is required.

Refer to the ACU Setup information to key in the required value of Elevation Trim.

5.

Continue with Azimuth trim, then re-target the satellite several times to verify that targeting is now driving the antenna to a position that is within +/- 1.0 degrees of where the satellite signal is located.

EXAMPLE: The ACU targets to an Elevation position of 30.0 degrees and an Azimuth position of 180.2 (Calculated), you find that Peak Elevation while ON your desired satellite is 31.5 degrees and Peak Azimuth is 178.0. You would enter an EL TRIM value of –1.5 degrees (displayed as -0015) and an AZ TRIM of +2.2 degrees (displayed as 0022).

After these trims values had been set, your peak on satellite Azimuth and Elevation displays would be very near 180.2 and 30.0 respectively.

8-1

4010W-33 Installation Manual Setup – Targeting

8.3.

EL TRIM

Elevation trim offset parameter is entered in tenths of degrees. Adjusts display to correct for antenna alignment errors or imbalances in the antenna system. Increase number to increase display. Refer to “Optimizing Targeting” in the

Setup section of your antenna manual.

To update: While in the EL TRIM sub-menu, press the LEFT arrow key to bring the cursor under the ones digit. Press the UP or DOWN arrow key to increment or decrement the selected digit. Minus values are entered by decrementing below zero. Use the LEFT or RIGHT arrow key to move the cursor left or right to select other characters to modify.

When you are finished modifying press ENTER to execute the new value OR press NEXT to abort and exit setup mode.

Continue with Azimuth trim, then re-target the satellite several times to verify that targeting is now driving the antenna to a position that is within +/- 1.0 degrees of where the satellite signal is located.

8.4.

AZ TRIM

Azimuth trim offset parameter is entered in tenths of degrees. Offsets true azimuth angle display to compensate for installation alignment errors when used with Ships Gyro Compass input reference. Azimuth Trim does not affect

REL azimuth reading. Increase number to increase displayed value. Refer to “Optimizing Targeting” in the Setup section of your antenna manual.

To update: While in the AZ TRIM sub-menu, press the LEFT arrow key to bring the cursor under the ones digit. Press the UP or DOWN arrow key to increment or decrement the selected digit. Minus values are entered by decrementing below zero. Use the LEFT or RIGHT arrow key to move the cursor left or right to select other characters to modify.

When you are finished modifying press ENTER to execute the new value OR press NEXT to abort and exit setup mode.

Then re-target the satellite several times to verify that targeting is now driving the antenna to a position that is within

+/- 1.0 degrees of where the satellite signal is located.

8-2

Setup – Home Flag Offset 4010W-33 Installation Manual

9.

Setup – Home Flag Offset

Home Flag Offset is used to calibrate the relative azimuth value of the antenna to the bow line of the ship. This assures that the encoder input increments/decrements from this initialization value so that the encoder does not have to be precision aligned.

When the antenna is pointed in-line with the bow (parallel to the bow) the “Relative” display value should be 000.0 Relative

(360.0 = 000.0). Good calibration is especially important if blockage mapping is used, because the values entered into the AZ

LIMIT parameters are entered in Relative Azimuth. The default Home Flag Offset value saved in the PCU is 000.

The Home Flag Sensor mounted on the pedestal is actuated by a metal tab mounted on the azimuth spindle which causes it to produce the “Home Flag” signal.

The default mounting of the radome is with its bow reference in-line with the bow and the base hatch in-line with the stern

(aft reference of the radome). There are valid reasons for mounting the ADE in a different orientation than the default.

One of these would be that the hatch of radome needs to be oriented inboard of the ship for safe entry into the dome (ie

ADE is mounted on the Port, or Starboard, edge of the ship and safe entry is only available from inboard deck or inboard mast rungs).

Observe initialization of the antenna. When Azimuth drives CW and then stops at “Home” position, VISUALLY compare the antennas pointing, while at Home position, to the bow-line of the ship (parallel to the Bow).

If it appears to be very close to being parallel to the bow, you will not need to change the HFO and should proceed with

Optimizing Targeting. When “Optimizing Targeting” small variations (up to +/- 5.0 degrees) in Azimuth can be easily corrected using the AZ TRIM parameter.

Figure 8-1 Antenna stops In-line with Bow

If it is NOT close (stops before the bow or continues to drive past the bow) HFO needs to be adjusted.

If the antenna is pointing to the LEFT of the bow line: If the antenna stops driving before the bow line, when targeting a satellite it will fall short of the desired satellite by exactly the same number of degrees that it fell short of the bow line. You must calibrate HFO using either of the methods below.

If the antenna is pointing to the RIGHT of the bow line: If the antenna continues to drive past the bow line, when targeting a satellite it will overshoot the desired satellite by exactly the same number of degrees that it went past the bow line. You must calibrate HFO using either of the methods below.

If you find that a large value of AZ TRIM parameter has been used to calibrate the antenna, This indicates that the

Relative position is incorrect and should be “calibrated” using the correct HFO value instead of an Azimuth Trim offset.

If the radome was purposely rotated, has a large value of AZ TRIM or was inaccurately installed (greater than +/- 5 degrees), there are twos way of setting Home Flag to compensate for the mounting error. They are:

9.1.

Electronic Calibration of Relative Antenna Position (Home Flag Offset)

Above, you VISUALLY compared the antenna pointing, while at “Home” position, to the bow-line of the ship and found that the antenna pointing was NOT close to being parallel to the bow-line. It stopped before the bow or went past the bow OR you found AZ TRIM has been set to a large value, therefore, HFO needs to be adjusted.

Ascertain the exact amount of error using the appropriate procedure below, enter the HFO to calibrate the antenna to the ship, save the value and re-initialize the antenna to begin using the new value.

9.1.1.

You Found a Large AZ TRIM value:

If Targeting has been optimized by entering a large value of AZ TRIM; First, verify that you are able to repeatably accurately target a desired satellite (within +/- 1.0 degrees). Then you can use the AZ TRIM value to calculate the value of HFO you should use (so you can set AZ TRIM to zero). AZ Trim is entered as the number of tenths of degrees. You will have to convert the AZ TRIM value to the nearest whole degree

(round up or down as needed). Calculated HFO value is also rounded to the nearest whole number.

9-1

4010W-33 Installation Manual Setup – Home Flag Offset

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.

9.1.2.

You Observe “Home” Pointing is LEFT of the Bow-line:

1.

In this example, I observe that the

Home position is short of the bow line.

2.

I estimate that it is about 45 degrees.

3.

I target my desired satellite and record the Calculated Azimuth to be

180.5.

4.

I drive UP (I estimated that I will need to go UP about 45 degrees) and finally find my desired satellite.

5.

Turn tracking ON to let the ACU peak the signal up. When peaked, the

Azimuth is 227.0 degrees.

6.

I subtract Calculated from Peak (227

– 0180.5 = 46.5) and difference is

46.5 degrees.

7.

I can calculate what the correct value for the Home position of the antenna Figure 9-2 Antenna stopped before the Bow by subtracting (because “home” was to the left of bow) this difference of 46.5 from the bow line position 360.0. Therefore “home” should be 313.5 Relative.

8.

I now calculate the HFO = (313.5 / 360) x 255 = 0.87 x 255 = 222.06 which I round off to 222.

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, use AZ TRIM in the Optimizing Targeting procedure to correct it.

9.1.3.

You Observe “Home” Pointing is RIGHT of the Bow-line:

1.

In this example, I observe that the

Home position is past the bow line.

2.

I estimate that it is about 90 degrees.

3.

I target my desired satellite and record the Calculated Azimuth to be 180.0.

4.

I drive DOWN (I estimated that I will need to go DOWN about 89 degrees) and finally find my desired satellite.

5.

Turn tracking ON to let the ACU peak the signal up. When peaked, the Azimuth is 90.0 degrees.

6.

I subtract Calculated from Peak

(180.0 – 90.0 = 90.0) and difference is 90.0 degrees.

7.

I can calculate what the correct value for the Home position of the antenna by adding (because

Figure 9-3 Antenna stops past the Bow

9-2

Setup – Home Flag Offset 4010W-33 Installation Manual

“home” was to the right of bow) this difference of 09.0 to the bow line position 000.0. Therefore

“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.

9.1.4.

To Enter the HFO value in the DAC_2202:

To enter the calculated HFO value, press & hold both LEFT and RIGHT arrows for six seconds to enter the parameter menu at the EL TRIM parameter window. Press DOWN arrow key numerous times (about 21) until you have selected the REMOTE COMMAND window.

In the REMOTE COMMAND window, press the LEFT arrow key until you have underscored the left most character in the displayed value (ie the A in "A0000"). Use the UP/DOWN arrow keys to increment/decrement the underscored character until it is upper case N (“N0000” should appear in the command window). Press the RIGHT arrow key to move the cursor under the most significant digit, then use the UP arrow key to increment it to a value of 6 (the display is now “N6000”). Set the three digits to the right of the 6 to the three digit HFO value from 000 to 255 (corresponding to 0 to 360 degrees) that you calculated above. Use the

LEFT/RIGHT keys to underscore the desired digit(s) then use the UP/DOWN arrow keys to increment/decrement the underscored value. When you have finished editing the display value, press ENTER to send the HFO value command to the PCU (but it is not save yet).

If you want to find out what the current HFO value is key in N6999 and hit ENTER.

When completed, you must save the desired HFO value. Press ENTER several times to select the REMOTE

PARAMETERS display. Press the LEFT or RIGHT arrow key to enter writing mode and then press the ENTER to save the HFO value in the PCUs NVRAM.

EXAMPLE: In the “You Observe “Home” Pointing is LEFT of the Bow-line” example above, the HFO calculated was 222. To enter this value:

1.

Set the Remote Command value to "N6222".

2.

Press ENTER to send this HFO to the PCU. The display should now show "N0222".

When completed, you must save the desired HFO value. Press ENTER several times to select the

REMOTE PARAMETERS display. Press the LEFT or RIGHT arrow key to enter writing mode and then press the ENTER to save the HFO value in the PCUs NVRAM.

You must drive the antenna CW in azimuth until the home switch is actuated, or re-initialize the antenna to

This resets the PCU on the antenna. The antenna will reinitialize with this command (Performs a similar function as a power reset of the antenna) and the new home flag offset value will be used to calibrate the

Relative position of the antenna.

Mechanical Calibration of Relative Antenna Position (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 picture).

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 screws in the belt retainer ring plate below the Home Flag Clamp assembly are 90 degrees apart (as shown in the

picture 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

Setup – Searching

10.1.

Searching Operation

The ACU will initiate an automated search pattern after AGC falls below the current Threshold setting (indicates that satellite signal has been lost). The SEARCH DELAY parameter sets the amount of delay, in seconds, that the ACU will wait after AGC has fallen below the threshold value before it starts a search.

Search can be initiated manually by pressing the NEXT key as many times as required to access the SETUP menu, then press the ENTER Key to access the SEARCH sub-menu and then press the UP arrow key (starts a search from the current antenna position). While in the SEARCH sub-menu, pressing the DOWN arrow key will stop the current search.

Search is terminated automatically when the AGC level exceeds the threshold value and Tracking begins.

The ACU can be configured to use one of three search patterns. Each of the search patterns are described below.

Each description includes information about the settings involved in configuring the ACU to select that particular pattern and the values that those settings would be set to, to optimize the pattern for your antenna model and the frequency band being used.

The dimensions and timing of the search pattern are determined by the SETUP parameters SEARCH INC, SEARCH

LIMIT, SEARCH DELAY and SWEEP INC. Search is also affected by the Threshold and the internal receiver settings under the Satellite menu. To change any one of these parameters, refer to “Changing the Search Parameters” procedures below.

All three search patterns are conducted in a two-axis pattern consisting of alternate movements in azimuth and elevation or along the polarization angle. The size and direction of the movements are increased and reversed every other time resulting in an increasing spiral pattern as shown.

10.1.1.

Default Standard (Box) Search Pattern

The factory default search pattern in the ACU is a standard “box” pattern. 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 – initially set to the default value. After targeting has been optimized, the search limit can be adjusted if desired.

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 – default value (this parameter is not used in this search pattern).

GYRO TYPE – must NOT be set to zero.

SAT REF mode – It is normally OFF as long as you have good gyro compass input. It MUST be

OFF when the elevation angle is greater than 75 degrees. It Must be ON if you are experiencing frequent, or constant, gyro read errors (error code 0001).

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 target the antenna. Initially the antenna will go to a position that is 8 degrees above the calculated elevation, until Azimuth and Polarization have had time to complete adjustment. Then the antenna will drive down to the calculated elevation, which is the “Start” of the search pattern in the graphic below.

The antenna will then search up in azimuth one Search Increment, search up one Search Increment in elevation, search down two Search Increments 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 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.

10-1

4010W-33 Installation Manual Setup – Searching

10.1.2.

Inclined Orbit Search Pattern

Some older satellites, in order to save fuel to keep them exactly positioned over the Equator, are in an inclined geosynchronous orbit. The satellite remains geosynchronous but is no longer geostationary. From a fixed observation point on Earth, it would appear to trace out a figure-eight with lobes oriented northsouthward once every twenty-four hours. The north-south excursions of the satellite may be too far off the center point for a default box search pattern to find that satellite at all times during the 24 hour period.

You can configure the ACU to do a special search pattern for a satellite that is in an inclined orbit by using the following settings:


SEARCH LIMIT – leave this set to the default value for your antenna model.



SWEEP INC – set to 192 if your antenna is a Series 04 or Series 06 or Series 09. Set to 193 if your antenna is a Series 97, Series 00 or Series 07. This parameter sets the sweep increment (shown in the graphic above) to be +/- 8.0 degrees above/below the satellite arc.

GYRO TYPE – must NOT be set to zero.

SAT REF mode – It is normally OFF as long as you have good gyro compass input. It MUST be

OFF when the elevation angle is greater than 75 degrees. It Must be ON if you are experiencing frequent, or constant, gyro read errors (error code 0001).

Target the desired satellite longitude value but include an odd tenths digit (ie if you desire to target inclined satellite 186.0 W you would key in SAT 186.1 W for the ACU to do an inclined search). The Antenna Control

Unit calculates the Azimuth, Elevation and Polarization values it will target the antenna to.

Initially the antenna will go to a calculated position that is half of SWEEP INCR degrees above, and perpendicular to, the satellite arc (along the same angle as polarization for the desired satellite). This position is the “Start” of the search pattern in the graphic above. Then the antenna will drive down along the polarization angle SWEEP INCR degrees, step one Search Increment to the right (parallel to the satellite arc), search up along the polarization angle SWEEP INCR degrees, step two Search Increments to the left, search down, etc expanding out in the search pattern until Search Limit is reached. When the end of the search pattern is reached, the ACU will retarget the antenna to the calculated Azimuth and Elevation point.

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, then target the antenna to start point shown in the graphic above and begin the search pattern again. This cycle will repeat until the desired satellite signal is found or the operator intervenes.

10-2


10.1.3.

No Gyro Search Pattern

If the ship does not have a gyro compass to use as a heading input to the Antenna Control Unit, you may manually key in the actual heading of the vessel and then re-target the desired satellite, every time you need to re-target a satellite, or configure the ACU to do a “No Gyro Search Pattern”.

You configure the ACU to use this pattern by using the following settings:


SEARCH LIMIT – leave this set to the default value.



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.

10.2.

Changing the Search Parameters

The information above described what some of these parameters need to be set to for a specific search pattern.

Below are some additional pieces of information on the other parameters and the steps to change any one of these parameters.

10.2.1.

AUTO THRES

Sets offset of AGC tracking threshold above the average noise floor. Units are in A/D counts, approximately

20 counts/dB. A setting of 0 disables auto threshold, therefore, the operator would have to manually enter a threshold value.

When AUTO THRESHOLD is enabled (any value between 1-255), the ACU automatically re-sets the AGC tracking threshold whenever the antenna Targets (AZ, EL or SAT) or Searches. The new AGC threshold is set to the average signal level input (approximate background noise level) plus the AUTO THRES offset value.

EXAMPLE: If the Noise Floor off satellite is 1000 counts of AGC and Auto Threshold is set to 100, Threshold will be set to approximately 1100 after the antenna has finished targeting or Searching.

To change the Automatic Threshold value OR manually set threshold; Note the Peak “on satellite” AGC value, move EL and note the “off satellite” (Noise Floor) AGC value. Calculate the Difference between Peak AGC and

Noise Floor AGC. AUTO THRES should be set to 1/3 (to ½) of the Difference. This will usually be around 100 counts (3 dB) for a typical antenna configuration. Changes to this parameter may be required based on carrier tracking frequency, possible adjacent satellite, or ambient interference with desired satellite.

To manually update, press the LEFT arrow key to bring the cursor up under the least significant character.

Continue to move the cursor until the desired character to be edited is underscored (selected). Use the UP or

DOWN arrow keys to increment or decrement the selected character.

EL STEP SIZE

For proper DishScan operation this parameter must be set to factory default value of 0000.





10.2.3.

AZ STEP SIZE






10.2.4.

STEP INTEGRAL


To manually update, press the LEFT arrow key to bring the cursor under the least significant character.




10-4


10.2.5.

SEARCH INC

Sets size of search pattern increment. Units are in pedestal step resolution (12 steps per degree). The suggested setting is equal to the full 3dB beamwidth of your antenna. Default value is 15 these systems.





10.2.6.

SEARCH LIMIT

Sets the overall peak to peak size of the search pattern. Units are in pedestal step resolution (12 steps per degree). Default value is 100 for these systems.

After you have optimized your Targeting (refer to Optimizing Targeting) you may wish to reduce the size of the Search pattern to avoid Tracking on an adjacent satellite (ie set to 50% of its default value so that in the future it will only search half as far from your targeted position).





10.2.7.

SEARCH DELAY

Sets the time-out for automatic initiation of a search operation when the signal level (AGC) drops below threshold. Units are in seconds. Range is 0-255 seconds. Default setting is 30 seconds. A setting of 0 disables the automatic search initiation.







10.2.8.

SWEEP INC

This parameter MUST be set for the desired azimuth sweep speed of a No Gyro search or the sweep increment dimension of an Inclined Orbit search (refer to the search pattern information above).

Setup – Blockage & RF Radiation Hazard Zones 4010W-33 Installation Manual

11.

Setup – Blockage & RF Radiation Hazard Zones

This section discusses how to set up blockage, or RF Radiation Hazard, zones in the ACU.

11.1.

Radiation Hazard and Blockage Mapping (AZ LIMIT parameters)

The ACU can be programmed with relative azimuth sectors (zones) where blockage exists or where transmit power would endanger personnel who are frequently in that area. Your ACU software may allow you to set four zones or it will only three zones and include +5 volt polarization.

When the AZ LIMIT parameters are set to create these ZONES (up to four), several things happen when the antenna is within one of the zones:

1.

Tracking continues as long as the AGC value is greater than the Threshold value. When the AGC value drops below Threshold, the antenna will wait “Search Delay” parameter amount of time and then re-target the satellite you targeted last (if 4 value is included in SYSTEM TYPE). Timeout and re-target will continue until the satellite is re-acquired and tracking can resume.

2.

“BLOCKED” will be displayed in the TRACKING window wherever the antenna is inside one of the zones.

3.

A contact closure to ground (or an open if the blockage logic is reversed – See SYSTEM TYPE 16 value) is provided on the SW2 terminal of the Terminal Mounting Strip. This Switch output provides a “Blocked”, “RF

Radiation Hazard” or “FCC TX Mute” logic output. When the antenna exits the zone it will be on satellite, tracking and the SW2 logic contact closure will open.

The lower and upper limits are user programmable and are stored in NVRAM within the ACU parameter list.

AZ LIMIT 1 is the Lower Relative AZ limit (this is the more counter-clockwise of the two points, even if it is numerically larger). AZ LIMIT 2 is the Upper Relative AZ limit (the more clockwise of the two points) for pattern mapping of ZONE 1. Enter the elevation value that represents the top of the blockage between the two azimuth limit points in the EL LIMIT 12 parameter.

AZ LIMIT 3 is the Lower Relative AZ limit (CCW point) and AZ LIMIT 4 is the Upper Relative AZ limit (CW point) for pattern mapping of ZONE 2. Enter the elevation value that represents the top of the blockage between the two azimuth limit points in the EL LIMIT 34 parameter.

AZ LIMIT 5 is the Lower Relative AZ limit (CCW point) and AZ LIMIT 6 is the Upper Relative AZ limit (CW point) for pattern mapping of ZONE 3. Enter the elevation value that represents the top of the blockage between the two azimuth limit points in the EL LIMIT 56 parameter.

AZ LIMIT 7 is the Lower Relative AZ limit (CCW point) and AZ LIMIT 8 is the Upper Relative AZ limit (CW point) for pattern mapping of ZONE 4. Enter the elevation value that represents the top of the blockage between the two azimuth limit points in the EL LIMIT 78 parameter. If your ACU software includes 5 volt polarization you will not see these AZ & EL LIMIT parameters.

CAUTION: The Lower Relative AZ limit is the more counter-clockwise of the two points (even if it is numerically larger) and the Upper Relative AZ limit is the more clockwise of the two points. If you enter the two relative points incorrectly, Tracking and Searching will be adversely affected.

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 mispointed 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

4010W-33 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 inline 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 2 - Three blockage Zones, Dual Antenna

configuration: A ship has 2 Sea Tel antennas, “Antenna

A” mounted on the port side and “Antenna B” mounted on the starboard side. Antenna A is designated as the master antenna and its zones would be set as in example 1 above.

The mast forward, Antenna A to port and the engine exhaust stack aft form the three zones where satellite signal is blocked from Antenna B. The SW2 logic output from Antenna A (ACU A) and Antenna B (ACU B) are used to control a “Dual Antenna Arbitrator”, which will route satellite signal from the un-blocked antenna to the other below decks equipment. If both antennas are tracking the same satellite, they will not both be blocked at the same time. The logic output will switch to provide satellite signal to the below decks equipment from Antenna A when it is

not blocked and will switch to provide satellite signal from Antenna B whenever Antenna A is blocked. The switches will not change state if both antennas are blocked, or if both are on satellite.

Antenna A is the same as the previous example and its ACU would be set to those AZ LIMIT values.

Antenna B ACU would be set to:

In this example Antenna B zone 1 is caused by the stack, zone 2 is from Antenna A, zone 3 is from the mast and zone

4 is not needed.

ZONE 1 begins (AZ LIMIT 1) at 188 degrees Relative and ends (AZ LIMIT 2) at 204 degrees Relative. Multiply these Relative positions by 10. Enter AZ LIMIT 1 value of 1880 and AZ LIMIT 2 value of 2040. In this case the stack height only causes blockage up to an elevation of 42 degrees, so we set EL LIMIT 12 to 0420. If the antenna is between these two AZ Limit points but the elevation is greater than 42 degrees, the antenna will no longer be blocked.

ZONE 2 begins (AZ LIMIT 3) at 254 degrees Relative and ends (AZ LIMIT 4) at 278 degrees Relative. Multiply these Relative positions by 10. Enter AZ LIMIT 3 value of 2540 and AZ LIMIT 4 value of 2780. In this case the Antenna B 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 342 degrees Relative and ends (AZ LIMIT 6) at 348 degrees Relative. Multiply these Relative positions by 10. Enter AZ LIMIT 5 value of 3420 and AZ LIMIT 6 value of 3480. In this case the mast height only causes blockage up to an elevation of 41 degrees, so we set EL LIMIT 56 to 0410. 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.



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.

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.












Enter AZ LIMIT 7 value of 1730 and AZ LIMIT 8 value of 1870. In this case the mast height only causes blockage up to an elevation of 55 degrees, so we set

EL LIMIT 78 to 0550. If the antenna is between these two AZ Limit points but the elevation is greater than

55 degrees, the antenna will no longer be blocked. If your ACU software includes 5 volt polarization you will not see these AZ & EL LIMIT parameters.

Setup – Modem Connections, Setup and Test

In order to be compliant with FCC Order 04-286 and WRC-03 Resolution 902 the Satellite Modem MUST be connected to the

Antenna control Unit/Terminal Mounting Strip to provide TX Mute control functionality. The FCC/WARC requirements have been adopted by ITU & ETSI for them to publish similar requirements. The current FCC/WARC requirements are:

• 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 is 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).

The connection will also provide External Modem Lock and GPS Latitude & Longitude.

The External Modem Lock output from a satellite modem into the ACU provides a positive Network ID input to the ACU when the antenna is on the desired satellite. This input is NOT used for Tracking purposes, it is only used for satellite identification to assure that the satellite which has been acquired is the correct satellite (else the ACU will resume searching).

The GPS output from the ACU provides the current ships Latitude & Longitude as an input to the satellite modem for mobile mode operation.

All modems must be set for mobile operation and have hardware handshaking turned ON.

12.5.

SYSTEM TYPE parameter

The System Type parameter is used to enable a variety of system functions. With this parameter value set to 0,

the DAC software functions will be as follows:

• External AGC, or Modem Lock, function is used to bring an external modem lock signal from a satellite modem into the ACU as a positive ID that the antenna is on the desired satellite. This input is NOT used for

Tracking purposes, it is only used during search to identify when the antenna has acquired the correct satellite. This external AGC function in the DAC software is disabled. Expected input is 0 VDC when the modem has RX sync/Network Lock and a positive voltage (+15 VDC max) when the does not have lock.

• LNB Voltage - This function enables the Tracking Receiver to output 13/18 VDC, and/or 22kHz Tone to power an LNB and/or control a Matrix Switch. This function is disabled.

• The blockage output (SW2) of the ACU is a short to ground circuit when the antenna is in a programmed blockage zone, is searching, or targeting and or is mis-pointed by 0.5 degrees or greater. Whenever one of these conditions exist a transistor on the main PCB in the ACU shorts to ground providing a current sink of

0.5 amps max to control below decks dual antenna coax switches or TX Mute control to a satellite modem

(for radiation hazard control or TX mute requirements for FCC compliance).

• Relative Azimuth value is normally only visible in the Antenna main menu display. The Azimuth entry menu normally displays Azimuth position, DishScan tracking signal and AGC.

• When Search limit is reached the antenna will return back to the origin of the search pattern.

• When the ACU power is turned ON it does not automatically target the satellite that was used last.

• Pressing RESET on the front panel of the ACU normally only resets the processors inside but does not retarget the satellite.

128 Reverse External Modem Lock input polarity (logic hi = lock).

If you know that the modem you will be using with the system provides requires a logic hi (+15 VDC max) when it has modem lock or you find the AGC reading for locked and unlocked conditions from your modem need to be reversed you must enable this function in your current SYSTEM TYPE parameter.

This is NOT recommended for Series 09 systems, because they ALL provide the LNB voltage at the pedestal.

Display Relative in the Azimuth entry display.

Enabling this function causes REL position to take the place of the DishScan signaling in the Azimuth entry display. Relative position of the antenna is RARELY more desirable than the DishScan signaling.

16 Reverse blockage output logic (SW2 logic hi = blocked).

If you know that the modem you will be using with the system requires a logic hi (open circuit) to mute or you find that the Modem is being muted when the antenna is ON satellite (and un-muted when the antenna is blocked, searching or targeting) you must enable this function in your current

SYSTEM TYPE parameter.

-- Reserved --

2

Enabling this function will cause the ACU to re-target the calculated satellite position (rather than returning to origin).

Enable External Modem Lock Input (logic low = lock)

This enables the ACU to use the external modem input. Expected input is logic low (0 VDC) when the modem has RX sync/Network Lock and a positive voltage (+15 VDC max) when the does not have lock. This function must be enabled to use the external input from ANY modem,

regardless of its locked/unlocked logic. [If you find the AGC reading for locked and unlocked conditions need to be reversed you must add 128 to your current SYSTEM TYPE parameter].

1 Auto SAT load on “hot” RESET and ACU Power-Up.

Enable this function if you want the ACU to automatically re-target the satellite whenever the system power is turned ON (after antenna initialization) or whenever the operator presses the

RESET button on the from panel of the ACU.

To change the SYSTEM TYPE parameter, press the LEFT arrow key to bring the cursor under the least significant character. Continue to move the cursor until the desired character to be edited is underscored (selected). Use the UP or DOWN arrow keys to increment or decrement the selected character. Use the LEFT or RIGHT arrow key to move the cursor left or right to select other characters to modify. When you are finished modifying press ENTER to execute the new value Continue pressing ENTER until SAVE NEW PARAMETERS is displayed, and then press the RIGHT arrow, UP arrow then ENTER to save the change(s).

12.6.

Blockage Simulation Test

Blockage output function is used to modify the behavior of Tracking and Searching when there is a known blockage zone. 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. This logic output control signal is used for:

• 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 signal is lost.

• In a “Dual Antenna” installation, this logic output(s) is used to control Dual Antenna Arbitrator panel of coax switches to switch the source inputs to the matrix switch from Antenna “A” to Antenna “B”, and vice versa.

12-3


• When used as simple “RF Radiation Hazard” logic output for a single Sea Tel TX/RX 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).

• When used for “FCC TX Mute” logic output for a single Sea Tel TX/RX antenna, this output could be 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 TX/RX 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 provides a ground to “Mute” the satellite modem on 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.

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).

Setup – Optimizing Polarity & Cross-Pol Isolation 4010W-33 Installation Manual

13.

Setup – Optimizing Polarity & Cross-Pol Isolation

The only way to optimize the polarization of the antenna properly is to peak the polarity angle while the system is in autopolarization mode. This automatically adjusts the polarization of the feed by calculating the required polarization angle for the feed every 2 seconds based on ship's Latitude, Longitude and the desired Satellite Longitude.

13.1.

Sat Skew setting

The Satellite Skew setting in the Satellite – Tracking Receiver sub-menu (prior to NID) is used to enter the skew of the satellite to optimize polarity angle.

This feature is used in conjunction with POL OFFSET to optimize polarization of the feed. POL OFFSET will serve to calibrate the feed itself (mechanical calibration) Before adjusting the SKEW parameter, target a satellite that is of your same longitudinal position (ie from Concord, CA at 38N and 122W we would target a satellite value of 122W). Drive the reflector to 0 or 5 degrees elevation (this is so you can easily view the feed). And verify that the feed is a pure vertical. This may be visually verified by placing a level bubble on the LNB itself. During Cross-Pol isolation tests, enter in the known skew value of the satellite, then as instructed by the NOC to drive the feed assembly, increase or decrease the SAT SKEW parameter. Each digit represented on this screen represents one whole degree of feed drive.

13.2.

Polarity Angle (POLANG) Parameters

First of all make sure that the polang parameters are set correctly:

1.

POL TYPE – should be set to 0072 (Auto-Pol mode).

2.

POL OFFSET – This is initially set to factory default (0040) but will be incremented, or decremented, to calibrate the feed to the horizon with a level (bubble or digital).

3.

POL SCALE – Leave this at the factory default setting of 0090.

4.

Go to the TX POLARITY parameter in the Setup menu of the ACU and set this parameter to your assigned

Transmit polarity (2=Horizontal or 4=Vertical).

5.

Target your desired satellite (as provided by you airtime provider).

6.

Verify the system has acquired the correct satellite, else continue searching until the correct satellite is acquired, and set your satellite modem (or spectrum analyzer) to view its signal level display.

7.

Allow tracking to peak the satellite signal.

8.

SAT SKEW – This setting will be incremented, or decremented, to optimize the polarity to peak the received satellite signal, and later to do cross-pol isolation with the airtime provider, network operation center or satellite provider.

13.3.

Optimizing Auto-Polarization on Receive Signal

This procedure optimizes the linear polarization of the feed based on the received signal level.

1.

Verify that tracking is ON and that the antenna is peaked on your targeted satellite (targeting calculates the azimuth, elevation and polarization angles).

2.

Go to the SAT SKEW parameter in the Satellite menu of the ACU. Default setting is 0000 and may be incremented, or decremented, to adjust polarization while in Auto-Pol mode. Each increment equals one degree of polarization rotation, decrement below 0000 for minus polarization.

3.

Press the RIGHT arrow to edit the current value.

4.

While watching the modems signal strength, the ACUs AGC value, or the spectrum analyzer satellite signal level, press the UP arrow to increment or the DOWN arrow to decrement the value and then hit the ENTER key to adjust the feed to the new value. Allow 10 seconds between increments or decrements to allow time for feed assembly to drive to new position.

5.

Press the RIGHT key again, make another small change in the same direction and hit ENTER to carry out the adjustment.

6.

Repeat this process of making small adjustments in the same direction until you see the modem signal strength, ACUs AGC value, or the spectrum analyzer satellite signal level decrease a noticeable amount (10 counts on the signal strength, 10 counts of AGC or ½ dB of signal level).

7.

Note the SAT SKEW value.

13-1

4010W-33 Installation Manual Setup – Optimizing Polarity & Cross-Pol Isolation

8.

Make a series of small changes in the opposite direction until you see the signal peak and then fall the same amount as noted in step 6.

9.

Note this SAT SKEW value.

10.

Set SAT SKEW to mid way between the value noted in step 7 & 9.

11.

Save your new SAT SKEW value.

13.4.

Optimizing Auto-Polarization Cross-Pol Isolation

During commissioning, under guidance from the network operation center, you will be adjusting to minimize the effect of your transmission on the opposite polarization which maximizes your Cross-Pol isolation. Contact your satellite provider to help you (over the phone) to optimize the polarity angle for maximum Cross-Pol isolation (this optimizes your transmit polarity and is much more accurate than trying to optimize your receive polarity).

1.

Verify that tracking is ON and that the antenna is peaked on your targeted satellite (targeting calculates the azimuth, elevation and polarization angles).

2.

Follow your service provider technicians instructions to set the modem to begin transmitting a CW (pure carrier) signal.

3.

Go to the SAT SKEW parameter in the Satellite menu of the ACU.

4.

Press the LEFT arrow to edit the current value.

5.

While under direction of the technician (on the phone), press the UP arrow to increment or the DOWN arrow to decrement the value and then hit the ENTER key to adjust the feed.

6.

The technician should indicate whether the adjustment you made improved, or worsened, the cross-pol isolation. If it improved he will have you make another small adjustment in the same direction. If it worsened he will have you make a small adjustment in the opposite direction.

7.

Press the RIGHT key again, make the next change as directed and hit ENTER to carry out the adjustment.

8.

Repeat this process of making small adjustments until the technician confirms that cross-pol isolation is optimized.

9.

Save your new SAT SKEW value.

14.7.

Satellite Reference Mode

The ships gyro compass input to the ACU may be accurate and stable in static conditions and yet may NOT be 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 mispointed 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.

I t is normally OFF as long as you have good gyro compass input. It MUST be OFF when the elevation angle is greater than 75 degrees.

Satellite Reference Mode MUST be ON when:

• No Gyro Compass is available

• Frequent or constant ACU Error Code 0001 (Gyro Compass has failed)

• Flux Gate Compass is being used

Installation Troubleshooting

This section describes the theory of operation to aid in troubleshooting and adjustments of the antenna system. Also refer to the Troubleshooting section of your ACU manual for additional troubleshooting details.

WARNING: Electrical Hazard – Dangerous AC Voltages exist in the Breaker Box and the Antenna

Pedestal Power Supply. Observe proper safety precautions when working inside the Antenna

Breaker Box or Power Supply.

WARNING: RF Radiation Hazard - This stabilized antenna system is designed to be used with transmit/receive equipment manufactured by others. Refer to the documentation supplied by the manufacturer which will describe potential hazards, including exposure to RF radiation, associated with the improper use of the transmit/receive equipment. Note that the transmit/receive equipment will operate independently of the stabilized antenna system.

The ultimate responsibility for safety rests with the facility operator and the individuals

who work on the system.

WARNING: RF Radiation Hazard - Prior to working on the stabilized antenna system, the power to the transmit/receive equipment must be locked out and tagged. Turning OFF power to the

Antenna Control Unit does NOT turn Transmit power output OFF.

The ultimate responsibility for safety rests with the facility operator and the individuals who work on the system.

WARNING: RF Radiation Hazard - When the transmit/receive system is in operation, no one should be allowed anywhere within the radiated beam being emitted from the reflector.

The ultimate responsibility for safety rests with the facility operator and the individuals who work on the system.

16-1

4010W-33 Installation Manual Installation Troubleshooting

Try pressing RESET first and then in some cases you may want to turn Power OFF for a short period of time then turn it back ON to see if that restores normal operation. Remember, with most Gyro Compass types (Synchro and SBS inputs) you MUST enter the beginning Heading value EVERY time you power-up the ACU, before you will be able to retarget your desired satellite.

Verify that the SETUP PARAMETERS are set correctly (refer to the Setup section of this manual).

16.2.1.

ACU display is blank

This indicates no power to the internal electronics. Assure that the front panel Power switch is ON. Check the AC line voltage on the Power Cord. Check the cables on the rear panel of the ACU to assure they are properly connected. If AC Line voltage is Ok, one at a time disconnect (and check display status) the cables plugged into J1 Gyro Compass, then J2 NMEA, then J3 M&C to see if one of these cables is shorting the ACU

Power. Call your dealer to report this failure and arrange for repair service.

16.2.2.

ACU Status displays "REMOTE NOT RESPONDING"

This indicates a problem in the Antenna Control coax cable or communications modems in the ACU and/or

Antenna PCU. Check the Antenna Control Cable connections at the J4 “Antenna” jack on the rear of the ACU and at the antenna pedestal inside the radome. If the connections are good, call your dealer to report this failure and arrange for repair service.

16.3.

Troubleshooting Ships Gyro Compass problems

Ships Heading display does not follow ships movement and/or you are getting frequent or constant ERROR CODE

0001. Determine the type of gyro compass that is used on the ship, assure that the GYRO TYPE parameter is set correctly (refer to the setup section of this manual) and then proceed to the step that lists the troubleshooting for the correct type of Gyro Compass Signal.

16.3.1.

STEP-BY-STEP

1.

Verify that the GYRO TYPE parameter is set correctly.

2.

Observe the ERROR LED on the FRONT panel. If it is illuminated, this indicates that an error was detected in the Step-By-Step input. Press RESET on the front panel. If the ERROR LED illuminates again, the problem is in the 4 connections to A, B, C and COMMON.

3.

Check the connections to the Terminal Mounting Strip and to the ACU.

4.

Measure the voltage between COMMON and A, B, and C. Each reading should either be near zero or

35 to 70 VDC. If all three are zero, check the repeater fuses. If some read negative and some read positive or if one reads an intermediate values the COMMON terminal is not properly connected.

5.

If the Ship - Heading display is different from the actual Gyro heading, access the Heading entry menu and key in the correct heading value (refer to the operation Ship menu section). Note the reading. After the ship has turned more than one degree, compare the new gyro heading with the reading on the display, if it has moved in the opposite direction then reverse connections A and B.

Reset the ACU, put in the correct ship's heading again and verify that the display reading now follows the Gyro heading.

16.3.2.

1:1 SYNCHRO

Observe the ship's heading display on the ACU. Compare its movement with that of the ship. If it does not move at all go to step 1. If it moves but in the wrong direction (even if it does not display the correct heading) go to step 2. If it moves in the correct direction but does not display the correct heading go to step

3. The gyro compass connects to the Terminal Mounting Strip on TB3 R1, R2, S1, S2 and S3.

CAUTION - Electrical Shock Potentials exist on the Gyro

Compass output lines. Assure that the Gyro Compass output is turned OFF when handling and connecting wiring to the

Terminal Mounting Strip.

1.

The Ships Heading display does not change when the ship changes direction. Using a multimeter read between R1 and R2. It should read 115 VAC. If it does not then a fuse is blown at the gyro repeater or there is an open between the repeater and the ACU. Read between S1 and S2, S2 and

16-2


S3 and finally S3 and S1. They should all read between 0 and 90 VAC. The voltage level will change as the ship turns. If one reading is very close to 0 volts wait until the ship has made a major change in heading and then check voltage again. If the reading is still very low there is a problem in the line between the gyro repeater and the ACU or a problem in the gyro repeater itself.

2.

The display changes in the direction opposite of the movement of the ship. Switch the secondary leads S1 and S2. Caution: there is 90 VAC between them! Verify that when the ship changes direction the display shows change in the same direction. If the direction is correct but the heading is incorrect go to step C.

3.

The ship's heading display does not indicate the correct heading. If the display is off by 60, 180 or

300 degrees, this indicates that R1 and R2 are reversed. Reverse R1 and R2 and recheck the heading display. If the display is off by 120 or 240 degrees, this indicates that S1, S2 and S3 are in the right order but off by one place. Note their positions and carefully move the connections one position over (S1 to S2, S2 to S3, and S3 to S1). This action will offset the display by 120 degrees. Check if the display now reads correctly. If not move all three leads one more time in the same direction as last time. Verify that the ship's heading is correct.

16.3.3.

360:1 Synchro

Observe the ship's heading display on the ACU. Compare its movement with that of the ship. If it does not move at all go to step 1. If it moves but in the wrong direction (even if it does not display the correct heading) go to step 2. If it moves in the correct direction but does not display the correct heading go to step

3. The gyro compass connects to the Terminal Mounting Strip on TB3- R1, R2, S1, S2 and S3.

CAUTION - Electrical Shock Potentials exist on the Gyro

Compass output lines. Assure that the Gyro Compass output is turned OFF when handling and connecting wiring to the

Terminal Mounting Strip.

1.

The Ships Heading display does not change when the ship changes direction. Using a multimeter read between R1 and R2. It should read 115 VAC. If it does not then a fuse is blown at the gyro repeater or there is an open between the repeater and the ACU. Read between S1 and S2, S2 and

S3 and finally S3 and S1. They should all read between 0 and 90 VAC. The voltage level will change as the ship turns. If one reading is very close to 0 volts wait until the ship has made a major change in heading and then check voltage again.

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.

Remove the standard cable pass through assembly 130818-1*

* N/A for 193 cm (76-inch) nominal size radomes. Refer to Fig 1, then use #2 Phillips screwdriver to remove 4 ea. attachment screws.

Use #2 Phillips screwdriver to remove 4 ea. screws.

131226 Rev A

Form # 117140-B


4.2 Making the holes

PLANNING: Space has been allowed for up to 5 ea. strain reliefs, but, install only as many as needed. (Typically only 2-3 for TX/RX systems). Refer to Fig 2 then plan which hole positions to use.

For 76-inch radomes lowest holes may be approx 1.5 inches from inside wall corner with floor (ref drawing 129416).

Note: The

hole center-to-center distance given is the MINIMUM.

B

A

C

Follow good engineering practice and provide the largest spacing possible between holes as follows:

1 Hole pattern - "A".

D

E

2 Hole pattern - "B", "C".

3 Hole pattern - "A", "B", "C", ("A", "D", "E" PERMITTED). Fig. 2 – Planning

4 Hole pattern - "B", "C", "D", "E". Measure in place or use

5 Hole pattern - “A”, "B", "C", "D", "E". template drawing 132234

Fig. 3 – (Up to) 5-Hole Pattern

131226 Rev A


4.3 Measure, mark and drill pilot holes

CAUTION: The hole locations cannot be determined accurately from outside of the radome.

Using full scale drawing 132234, provided in the strain relief kit, measure mark and drill pilot holes from the inside out, and using only light pressure, use the small drill bit, (~1/8” dia) to make a pilot hole through each planned location.

4.4 Use the hole saw from the outside with light pressure.

CAUTION: Using the hole saw from the inside is likely to damage the Gel Coat.

CAUTION: Heavy pressure on the hole saw from the inside is likely to damage the Gel Coat and splinter the fiberglass.

Working from the outside, use a 1-3/8” hole saw to make the holes for the planned strain reliefs.

4.5

4.6

4.7

After holes are drilled CAREFULLY use a file to clean the hole edges.

Test fit the strain reliefs in each location, then, make adjustments as necessary.

Sealing the hole edges.

CAUTION: Cut edges can allow water and/or ice ingress and weaken the fiberglass laminate or structural foam. It is essential to seal all cut edges thoroughly with fiberglass resin to preserve the radome’s structural strength.

CAUTION: Fiberglass paste or RTV silicone sealant will not wick into and seal the fiberglass strands as well as fiberglass resin, ONLY use fiberglass resin (such as TAP PLASTICS MARINE VINYL ESTER, or equivalent) for sealing the cut edges.

Follow the manufacturer’s instructions to mix a small amount of fiberglass resin and catalyst, then working quickly, use a disposable brush to apply mixed fiberglass resin to the hole edges, both inside and out.

Allow the fiberglass resin to set per resin manufacturer’s instructions.

Note: Like all chemical reactions, set time will be temperature/humidity dependent.

4.8 Refer to strain relief assembly drawing 124903

Being careful not to damage either the radome or the strain relief threads, use adjustable pliers to install strain reliefs.

4.9 Rotate General Assembly (G.A.)

Once cables have been installed, rotate General Assembly (G.A.), to ensure cables are routed properly and do not interfere with azimuth rotation.
