Installation

54-0147 Rev. G

Plan the entire installation before proceeding! Take into account antenna unit placement, running cable distances between units, and accessibility to the equipment after installation. Cable lengths are detailed in Tables 2-2 and 2-3 on the following page.

KVH recommends the use of RG-11 (75 ohms) cable for RF wiring. Use of non-RG-11 (75 ohms) cables will result in degraded performance.The KVH warranty does not cover degraded performance due to improper wiring.

Table 2-1

Installation Process

Recommended ADCU to Ship’s Power Cabling

The following cable sizes are recommended for the specified running lengths and are based on Lloyd’s and ABYC specifications. Cable jacketing should meet marine insulation standards while the cable should be tinned, stranded marine stock.

2.1 Choosing the Best Location and

Getting the Best Reception

There are several factors to consider when choosing the respective locations of the TracVision G4 antenna unit and GyroTrac sensor components.

2.1.1 Selecting the Best Location for the

TracVision G4 Antenna Unit

• The ideal antenna site has a clear view of the

horizon/satellite all around.

2-2

TracVision G4 Installation and Technical Manual

The radome exterior is treated with a special finish selected for compatibility with the dome material and transparency to the satellite signals. Application of additional paints or finishes WILL degrade performance, potentially beyond acceptable limits.

Table 2-2

Recommended ADCU-to-Ship’s

Power Cable Specifications

Table 2-3

Lengths of Provided

Below-decks Cables

The power cable connector on the base of the Antenna Unit cannot accept cables thicker than 14 AWG (1.5 mm2). Refer to Section 2.4.2,

“Providing Power to the Antenna Unit,” for more details.

• Tracking errors will be reduced if the antenna

forward arrow is aligned as closely as possible with the vessel’s centerline.

• Place the Antenna Unit as close to the intersection

of the vessel’s fore-and-aft centerline and midships.

• Keep the antenna out of line with nearby radars,

as their energy levels may overload the antenna’s front-end circuits. If necessary, position the Antenna Unit so it is at least four feet (1.3 meters) above or below the level of the radar.

• Make sure that the mounting surface is rigid so

that it cannot flex when the vessel vibrates. If necessary, add a strength member to the mounting site to stiffen it.

2.1.2 Selecting the Best Location for the GyroTrac Sensor Components

Ideally, the GyroTrac sensor module should be mounted as low as possible in the center of the vessel – but NOT in the bilges.

• Place the Sensor Module as far as practical

(minimum 3 ft./0.9 m) from magnetized or magnetizable materials.

•

Maintain at least 4 feet (1.3 m) separation between the Sensor Module and any large ferrous masses, cables carrying high amperage direct current, or battery banks.

• Be alert for devices that change their magnetic

characteristics when in use, such as CRTs, computer and TV screens, radar magnetrons, electric winches, loudspeakers, windshield wipers, and other devices with DC motors. GyroTrac cannot compensate for changing magnetic fields created by these devices.

•

If it is necessary to fabricate custom mounting brackets for the Sensor Module, they should be made from non-ferrous materials such as wood, brass, aluminum, fiberglass, or plastic.

2-3

Installation

Be certain to isolate the Sensor Module from ground (i.e., the ship’s hull) by always using the fiber washers when attaching the Horizontal Sensor Bracket to either a mounting surface or the Vertical Sensor Bracket.

The Antenna Unit should not be too high off the water (a height above the waterline no more than half the vessel length).

If uncertain of the best location for the sensor module, make a temporary installation and conduct a compass calibration (as described in Section 2.5, “Calibrating the Sensor Module”). Any necessary adjustments to the sensor location can be made based on the calibration scores.

Mounting on Steel Vessels

The GyroTrac sensor module is a digital magnetic compass and great care is required when positioning the unit on steel-hulled craft. The ideal location is in the wheelhouse or above decks. Mount on an aluminum pole or bracket, well away from magnetic fields such as cranes, derricks, motors, radomes,

antennas, etc. DO NOT mount the sensor module on a steel or

iron platform. Use aluminum, brass, plastic, or wood.

2.2 Installing the Antenna Unit

Specifics of installation will vary with vessel design but the following procedures are applicable in most situations and will result in a secure and effective installation.

Table 2-4 lists the components provided in the Antenna Unit Installation kitpack.

Tips for Successful Antenna Unit Placement and Mounting

• The mounting surface should be essentially flat,

free of vibration and flexing, and strong enough to carry the complete assembly (30 lbs/13.6 kg).

• The antenna unit need not be located exactly on

the vessel’s fore-and-aft axis, but its centerline reference MUST be parallel to it.

• Be sure to account for the radome height and the

base dimensions, illustrated in Figure 2-1 on the following page.

2-4

TracVision G4 Installation and Technical Manual

Table 2-4

Antenna Unit Kitpack Contents

Always lift the antenna unit by the gray baseplate structure, not the radome. Also be careful not to strike the exposed connectors extending from the bottom of the baseplate or allow them to carry the weight of the antenna unit.

Antenna Unit Mounting Procedure

1. Using the base dimensions presented in Figure 2-2 or the template provided in Appendix B, lay out the four mounting bolt holes. Check the layout to make certain the baseplate will be parallel with the vessel’s fore/aft axis.

2. Drill four

⁄8" (10 mm) bolt holes. Mark a 3" (80 mm) diameter circle in the center of the pattern and cut out to make a passage for the cables to connect to the baseplate. Smooth the edges of the hole to protect the cables.

3. Place the foam seal in position on the mounting surface with the hole centered over the cable access cutout and the paper backing on the bottom. Do not remove the paper backing at this time. Align the seal with the vessel’s fore-and-aft line and the small end pointed forward as shown in Figure 2-3. Scribe a line all around the seal.

4. Remove and save the three screws holding the radome to the baseplate. Carefully lift the radome straight up until clear of the antenna assembly and set it aside in a safe place.

5. Position the baseplate assembly in place over the mounting holes and cable access. Ensure that all holes line up and that the connectors are centered over the cable access. Make any necessary adjustments before seating the foam seal in place permanently.

6. Clean the surface where the foam seal will be placed. Remove the paper backing from the foam seal to expose the contact cement. Lay the foam seal in place, adhesive side down, and press down firmly to bring the adhesive into full contact along the bottom. Ensure the narrow end points toward the

bow.

7. Bring the Data Cable, RF Cable(s), and Power Cable up through the access hole and connect them to the baseplate. Turn the connectors down securely, but don’t use excessive force; finger-tight is sufficient. Figure 2-4 illustrates the connector assignments.

Do not use teflon gel on the cable fittings as it reduces signal strength at higher frequencies.

8. Remove the foam shipping restraint from the Antenna Unit.

9. Place the baseplate over the holes drilled in the foundation, ensuring the forward arrow points toward the bow. Rotate the azimuth mechanism plate to expose each mounting hole. When rotating

the azimuth mechanism by hand, go slowly. Hitting the stops with excessive force will damage the azimuth limit switch.

10. Place a flat washer from the kitpack on a bolt and

insert the bolt into its hole from above as shown in

Figure 2-5 on the following page.

2.3.2 Mounting the Sensor Module

The GyroTrac Sensor Module comes equipped with two mounting brackets. The first is the Horizontal Sensor Bracket, which attaches directly to the Sensor Module housing, and must

be used in all mounting arrangements.

The Vertical Sensor Bracket allows the Sensor Module to be mounted on a vertical surface. The following steps detail the correct use of each bracket.

These brackets should enable the Sensor Module to be placed as level in pitch and roll as possible. If you are unable to place the Sensor Module in a level arrangement, refer to Section 3.5.3, “Entering Gyro Offset Values” to compensate.

Horizontal Bracket Only

1. Choose a mounting location free of excessive vibration and flexing.

2. The module must be oriented so that the forward reference on the end cap is pointed forward and parallel to the vessel’s fore-and-aft axis (to ±5°). The proper orientation is illustrated in Figure 2-8.

3. Position the Horizontal Sensor Bracket so that the Sensor Module will be properly oriented when placed in the bracket.

4. Use the holes in the bracket feet to spot for mounting screws. Center punch and drill 4 holes with a

⁄8" (0.125" or 3.5 mm) bit.

5. As illustrated in Figure 2-9, position the bracket over the mounting holes.

- Insert fiber washers into both sides of mounting

bracket.

- Insert #8 flat washers and #8 Type BP pan head

screws into the holes.

6. Place the Sensor Module in the bracket with the proper orientation (up/forward).

7. Thread #10 machine screws through lock washers, flat washers, and bracket, and then into the captive extrusion T-nuts within the Sensor Module housing as illustrated in Figure 2-9.

Horizontal and Vertical Bracket

1. Choose a mounting location free of excessive vibration and flexing.

2. The module must be oriented so that the forward reference on the end cap is pointed forward and parallel to the vessel’s fore-and-aft axis. See Figure 2-8 for reference. The brackets are designed so that the Sensor Module may be mounted perpendicular (option 1) or parallel (option 2) to the mounting surface as pictured in Figure 2-10.

3. The module must be level with the vessel’s deck. This placement can be fine tuned by using the ADCU pitch and roll data. Adjust the brackets so that the pitch and roll are 0 (zero) when the vessel is docked and under normal load.

9. Thread #10 machine screws through lock washers, flat washers, and bracket, and then into the captive extrusion T-nuts within the Sensor Module housing.

2.3.3 Mounting the ADCU

The ADCU may be mounted in one of two ways: either directly to a horizontal surface using Velcro fasteners or flush to a control panel. Both the fasteners and the Flush Mount Bracket are included as part of the GyroTrac package.

Some tips for installing the ADCU:

• The ADCU should be placed in a dry location that

is convenient for the user.

• It is not susceptible to magnetic interference nor

must it be situated on a level surface.

•

It should be placed so the LCD display is visible and buttons are accessible.

• Allow room at the back to connect cables to the

rear panel.

Velcro Fastening

1. Choose a flat, stable location.

2. Remove the two strips of velcro fabric from the kitpack. Clean the bottom of the housing with a mild detergent and water to remove oils, etc. Peel the protective backing from the strips and apply them to the bottom of the housing at each of the four corners.

3. Position the four hook disks where the ADCU will be mounted. Drill screw holes for the disks and attach. Press the ADCU firmly into place so the loop material engages the hook disks.

Flush-mounting the ADCU

1. A template has been provided in Appendix B as a guide to mark and cut the proper hole for the Flush Mount Bracket. Cut the hole and make certain the bracket and ADCU will fit easily.

2. Attach the Flush Mount Bracket to the ADCU by loosening the two screws on the underside of the ADCU. Slide the Flush Mount Bracket backward over the ADCU until the two notches meet the screws as shown in Figure 2-13.

3. Tighten the screws to secure the ADCU to the bracket.

Tips for Successful and Safe Wiring

• When inserting a wire into the terminal connector,

make certain wire insulation is not pinched in the connector.

• After inserting and securing wire, tug gently to

ensure that the connection is solid.

•

Position cables behind the ADCU so that they connect neatly to the terminal strips.

• Do not tin (solder) the wire ends.

Effective Strain Relief for ADCU Terminal Connections

Due to both the potential number of wires that will be connecting to the rear of the ADCU and the dynamic environment aboard ship, it is critical that the terminal connections are properly strain relieved using tie-wraps (a number of which are included with the GyroTrac kitpack).

Some things to consider when strain relieving cables:

• There should be no tension on the wires

connecting to the terminal strip. Removing slack is important but the wires should not be taut.

• If the cable is equipped with a ferrite, the ferrite

should be as close as possible to the terminal connections.

•

Strain relieve wires and cables as close to the ferrite as possible. A good arrangement includes a tie-wrap behind the ferrite (on the side furthest from the ADCU); an ideal design includes a tiewrap on either side of the ferrite.

Examples of Effective Strain Relief

Double-check all wiring. Be certain to plug terminal strips into the correct positions. If wiring is incomplete or incorrect or the terminal strips exchange positions, serious electrical damage can occur to the TracVision G4 Antenna Unit, the GyroTrac, and interfacing electronics.

2.4.1 Wiring the Antenna Unit to the GyroTrac ADCU

Each cable provided with TracVision G4 should be routed and dressed before terminating at the ADCU. Note that the Data and Power cables have individual wires on one end. These can be trimmed to a shorter length if desired.

The TracVision G4 satellite TV system connects directly to the ADCU via the top two terminal connector strips as follows:

A comprehensive wiring diagram of the entire TracVision G4

system has been provided for technical reference in Appendix C. A

color quick reference guide to wiring your TracVision G4 has also been printed on the front cover of this manual.

2.4.2 Providing Power to the Antenna Unit

For single-switch convenience, the ADCU has been designed to serve as a junction box between ship’s power and the Antenna Unit as illustrated in Figure 2-17. However, the Antenna Unit can

be connected to a separate switch and breaker if it is more convenient or if the ADCU is placed more than 50 ft (15 m) from the Antenna Unit.

If there is a need to extend the Antenna Unit-to-ship’s power cable, refer to the following tips:

• The Antenna Unit power cable connector cannot accept cables larger than 14 AWG (1.5 mm

• If the cable is longer than 50 ft (15 m), be sure to verify the voltage at the antenna to ensure that there is sufficient power to drive the antenna under load (11-16 Vdc). If not, carefully increase the voltage to the Antenna Unit to compensate for any drop in power over the length of the cable and ensure that the voltage reaching the Antenna Unit is between 11 and 16 Vdc.

2.4.3 Connecting External Devices to the GyroTrac ADCU

All connections between the ADCU and external devices are made at the connector strips located on the rear of the ADCU. Follow these guidelines when wiring additional equipment to the ADCU:

• Make certain any additional equipment complies

with NMEA Standard 2.2.

•

Data conductor wire should be minimum 18 AWG (0.75 mm

), twisted pair, stranded, tinned marine

cable.

• Do not use cables with wire diameter larger than

12 AWG (2.5 mm

), as the connector plugs on the rear of the ADCU accept wire no larger than 12 AWG (2.5 mm

) size.

• Cables provided with optional KVH displays and

interface units are fully compatible with GyroTrac requirements. Note that cables to other external devices should follow the manufacturer’s recommendations.

• For power cable specifications, refer to Table 2-2 at the beginning of this section.

2-15

Installation

54-0147 Rev. G

If the ADCU is receiving data from a ship’s gyro, all compass outputs are automatically configured as Tr ue Nor th and cannot be set as Magnetic.

Power supplied to the TracVision G4 MUST NOT exceed 16 Vdc or the TracVision power supply will suff

er serious damage!

Appendix D provides instructions on properly wiring optional KVH equipment to the GyroTrac system.

2.4.4 GyroTrac Wiring Diagram

Figure 2-18 presents a complete wiring diagram for each GyroTrac terminal connector strip.

As noted in Figure 2-18, the output for Serial Ports 2 and 3 can vary from 4800 baud to 9600 baud. This is determined automatically based upon the selected output. Serial Port 1 provides 4800 baud output only.

FURUNO DATA

When the TracVision G4 antenna is connected to the GyroTrac system, GyroTrac Serial Port 3 will not provide output to other equipment. Serial Port 3 will only provide outputs if the antenna unit is disconnected from the ADCU and GyroTrac is configured to operate as a standalone system as described in Section 3.5.5,

“Selecting TracVision or GyroTrac-only Operations.”

2.4.5 Wiring the GyroTrac Sine/Cosine Interface

The GyroTrac ADCU sine/cosine interface provides the following outputs:

• sine

• cosine

• inverse sine

• inverse cosine

• reference voltage

Because the reference voltage is a reference output, not an input, connecting this output to another reference output from an autopilot or other system will cause problems.

In this case, connect the following wires from the autopilot (or other system) to the ADCU:

Autopilot/Other System Wire ADCU Terminal

Sine 12 Cosine 10 Internal Power Ground 7

(not chassis ground!) Reference (INPUT) 8 (KVH Output)

DO NOT connect the autopilot or other system to the ADCU reference output (ADCU terminal 8) if the autopilot has its own internal reference. Review the user’s manual for the selected equipment.

To adjust the GyroTrac reference to match the reference of the autopilot (or other system), connect a voltmeter to GyroTrac ADCU terminal (#8) and the reference terminal of the autopilot (or other system). Adjust the GyroTrac reference voltage as described in Section 3.4.1, “Setting the Sine/Cosine Data Output,” until the voltmeter indicates 0 VDC.

2-17

Installation

54-0147 Rev. G

Table 2-6

GyroTrac/Autopilot Sine/Cosine Wiring Arrangement

Before connecting the Autopilot internal ground to ADCU terminal 7, use a low impedance voltmeter to make certain that there is no DC voltage between the two terminals. A DC surge could damage one or both systems.

The sine/cosine reference voltage is an OUTPUT, not an INPUT. Connecting this output to the reference output for an autopilot or other system can result in problems. Section 2.4.5 provides instructions on how to solve this problem.

The sine/cosine interface should now operate with optimal precision.

2.4.6 True North Capability

GyroTrac is capable of determining true north that is accurate, under most conditions, to within ±1.0˚. This information is obtained by providing GPS data input and reading the magnetic variance tables.

NMEA sentences from the GPS must contain one or all of the following sentences: VTG, VHW, or BWC. The sentence structure must comply with the NMEA 0183 V2.20 standard and run at 4800 bps 8.N.1.

As illustrated in Figure 2-18 and the GyroTrac quick reference wiring guide on the back cover of this manual, GPS interface cables connect to the ADCU at terminals 23 and 24. Refer to your GPS user manual for the correct NMEA data out configuration.

2.4.7 Connecting a PC to the ADCU

Locate cable 32-0513-15. For purposes of diagnostics and maintenance, it is occasionally necessary to hook up a PC to the system. This may be done using the DB9 maintenance port on the back of the ADCU. To do so, connect the DB9 (female) to the PC and the DB9 (male) to the ADCU.

2.4.8 Connecting an Antenna RF Signal Cable to the IRD

The RF signal cable is fitted with F-type connectors. One end should be connected to the plug labeled “RF1” on the base of the TracVision G4 system. The other connector should be connected to the IRD plug labeled “LNB” or “ANT/SAT.” If a second IRD is to be hooked up to the TracVision G4 antenna unit, the RF cable

2.4.8.1 Connecting the IRD Ground Cable

A grounding wire has been provided to connect your IRD to a suitable ground. Attach the grounding wire to any suitable screw on the rear panel of the IRD with a good contact with the IRD chassis. The other end should be connected to a suitable ground, ideally to connector 2 of the ADCU terminal (see Figure 2-18).

2.4.8.2 Connecting the Antenna RF Signal Cables to a Multiswitch (North

American Systems Only)

Due to the signal polarization of North American satellites, it is possible for TracVision G4 to support more than two IRDs aboard a vessel. To install more than two IRD/TV pairs, an active multiswitch (Channel Master model 6214IFD or equivalent) is placed between the Antenna Unit and the IRDs. The following sections provide details for both a single multiswitch and a multiple multiswitch installation.

Multiswitch Installation for 3-4 IRD/TV Pairs

Figure 2-21 on the following page illustrates typical wiring arrangements for three or four IRDs. Mount the multiswitch unit in accordance with the manufacturer’s instruction sheet.

1. Connect the RF cable tagged "RF1" to the multiswitch input labeled "LNB RHCP +13V".

2. Connect a second RF cable to the antenna unit’s RF2 plug and to the multiswitch input labeled "LNB LHCP +18V".

3. Connect the multiswitch outputs to individual IRD inputs. Use RG-6 cable terminated with F-type connectors for all RF connections. Terminate all unused output connectors with 75 ohm DC blocks (Channel Master #7184, Radio Shack #15-1259 or equivalent).

2-19

Installation

54-0147 Rev. G

Some multiswitches (either active or passive), such as the Channel Master model 6214IFD, may interfere with the 22 KHz tone sent by DSS Plus™ IRDs to the antenna. As a result, the antenna may not receive the signal to change satellites when you change channels using your DSS Plus remote. In this case, you will need to use the maintenance port satellite switch procedure explained in Section 3.2, “Data Display and

Accessing the Main Menu.”

The IRD that is connected to the RF1 cable controls which satellite the antenna is tracking.The IRD connected to RF2 can select different channels on that satellite but not change the satellite selection itself.

Multiple Multiswitch Installation

If there is a need for more than four IRDs, it is possible to carry out a multiple multiswitch installation, as illustrated in Figure 2-22.

2.4.9 Connecting the ADCU to Vessel Power

Short circuits may result in severe electrical shock or burns. Turn off vessel power and test the circuit to ensure that no power is present before connecting any power cables.

The TracVision G4 system does not have a dedicated power control (ON/OFF switch). A quick-tripping circuit breaker or fuse should be installed between vessel power and the ADCU. Circuit overload protection should be rated for 5 amperes. For recommended power cable specifications, refer to Table 2-2 at the beginning of this section.

If vessel power fluctuates widely or is noisy, a wide-range DC/DC converter power supply should be installed. Test the

voltage and polarity before making connections to vessel power.

If the user-supplied power cable has a drain or shielded

wire, DO NOT connect the drain or shield to either the ADCU

or to ground.

2.5 Calibrating the Sensor Module

Although every Sensor Module is calibrated at the factory, hard and soft iron effects on the host platform can distort the local magnetic field, causing errors in the reported heading. These errors are minimized by proper location of the Sensor Module and are further removed by GyroTrac’s autocompensation feature, which measures the surrounding magnetic field distortions and compensates for them, thereby removing the resulting heading errors and giving you a system with better than ±1˚ accuracy in most cases.

It is critical that the compensation procedure be performed and a good calibration score be achieved following GyroTrac’s installation. This will ensure the accuracy of GyroTrac’s measurements and the data it provides to your other onboard systems. Failure to properly calibrate the system may result in an autocalibration conducted under less-than-ideal circumstances. To ensure that some form of calibration occurs after installation, GyroTrac leaves the factory with its autocompensation feature turned on because any compensation is better than none. Autocompensation will automatically shut off if a Calibration Accuracy of <8˚ or better is recorded. However, <8˚

The ADCU is equipped with fuses to protect against high-voltage spikes.If the system is installed correctly and power is available, but the system is non-functional, refer to Section 4, “Troubleshooting,” for instructions on checking and replacing the fuses.

You must compensate the GyroTrac Sensor Module after installation so that any errors due to metal and magnetism in your vessel are removed!

Power supplied to the TracVision G4 MUST NOT exceed 16V or the TracVision power supply will suff

accuracy is insufficient for precision heading measurements. KVH recommends that you follow the procedure outlined in the following sections to ensure that your system is calibrated properly.

2.5.1 Compensating the GyroTrac

Select a calm day and a clear area. Avoid excessive pitching and rolling, as this can distort the compensation data.

1. Apply power to the GyroTrac and note your approximate heading so that you will know when you have completed a full circle.

2. Steer your boat at a slow, steady speed through a full circle that takes at least 2 minutes to complete. (Try to time your turn so that it takes 30 seconds or more to turn 90º.) After completing a full circle, continue the process with a second circle. The circles do not need to be perfectly round as long as you make a complete 360º turn.

3. Once you have completed two full circles, your compass should be compensated. Check the calibration score as described in the next section.

2.5.2 The Calibration Score

Each compensation results in a calibration score, pictured in Figure 2-23, that is stored in the system’s memory.

ACC (Calibration Accuracy)

The ACC data indicates the degree of accuracy the GyroTrac will provide based on the quality of the last calibration. Table 2-7 lists the five possible accuracy levels.

MAGENV (Magnetic Environment)

The MAGENV score (GOOD, OK, POOR, BAD) indicates the quality of the installation location. If the quality is POOR or BAD, the Sensor Module probably should be moved to a more favorable magnetic environment.

CAL # (Calibration Update Number)

The CAL # indicates the number of times the deviation table has been updated. It is used primarily to verify whether a new calibration has been accepted by the system.

2.6 Commissioning the IRD

Before it can be used, your IRD must be commissioned and/or programmed.

Please refer to the user manual that accompanied your IRD for instructions on properly commissioning the system.

Programming European IRDs

Before the TracVision G4 system can be used in Europe, the IRD must be programmed to receive signals from the selected DVB satellite services. Programming is conducted using menu selections displayed on the TV screen. Please refer to the owner’s manual of your IRD for specific instructions.

Table 2-8 provides some key data for use when programming the IRD.

Configuration Item Setting

Antenna Alternative 1 DiSEqC 1 Antenna Alternative 2 DiSEqC 2 LNB Frequency Universal

It is also important that the IRD’s settings for Antenna Alternatives 1 and 2 match the ADCU’s installed satellite settings as follows:

• Antenna Alternative 1 = Satellite A

• Antenna Alternative 2 = Satellite B

Section 2.7, “Installing Satellites on the ADCU,” provides details on the satellite installation process.

Programming DSS Plus IRDs

If you are using multiple DSS Plus IRDs and intend to shift from

one satellite to another, only one of the IRDs can be configured as

a two-satellite receiver. All other IRDs must be configured as onesatellite receivers. The two-satellite IRD will determine which satellite the antenna is tracking while the other receivers can watch any channels available via that satellite. Refer to your IRD user manual for complete details on this process.

Accessing the TracVision G4 RF Board

To program the user-defined satellites into the TracVision G4 satellite library, it is necessary to connect a PC to the terminal maintenance port. This procedure requires terminal emulation software such as PROCOMM, Windows Terminal, or Windows 95/98 Hyperterminal. Use the settings appropriate to your application and follow this procedure.

1. Connect one end of the PC/ADCU cable to the DB9 connector on the rear of the ADCU. Connect the other end to the serial port on the PC (a 9-pin/25-pin connector adapter may be needed for some PCs).

2. Open the terminal emulation software and establish the following settings:

• 9600 baud

• no parity

• 8 data bits

• 1 start bit

• 1 stop bit

• no flow control

3. Apply power to the TracVision G4 system and allow the system to complete full initialization. Data should be scrolling on the PC display to identify any system problems detected. If no data is seen, recheck your connections and the terminal software setup.

Entering User-defined Satellite Data

Once the link between the PC and the TracVision G4 is established, it is necessary to provide initial longitude data regarding the user-defined satellite. To do so, enter the SATCONFIG parser command via PC as follows:

Command: SATCONFIG,USERX,YYY,Z,D,L<cr> Where: X = 1 or 2 (satellite alternative)

YYY = longitude (0-180) Z = E (East) or W (West) D = decoding type (0=test, 1=DSS-A, 2=DSS-B,

3=DVB) L = LNB polarization (C=circular, L=linear)

Function: configures one of the user-configurable satellites

with the longitude provided

Response: if valid entry, echoes the input data

if invalid entry, retur ns error message

After entering the SATCONFIG command, you must turn on the DEBUG mode by typing

@DEBUGON.

After entering the SATCONFIG and DEBUGON commands, enter the satellite transponder information via PC as follows:

Command: @SATCONFIG,X,N,F,S,C,ID,P,B,D<cr>

Where: @SATCONFIG = directs data to the RF Board

X = satellite location A or B N = satellite table # (98 & 99 are slots for user-

configured satellites) F = frequency in MHz (either 00000 or a range from

10700 - 12700) S = the satellite transponder symbol rate in

Mbit/second (01000 - 29999) C = the FEC code (e.g., 12, 23, 34, 56, 67, 78) ID = the satellite network ID in hexidecimal format

(0x####) P = the LNB polarization (v=vertical, h=horizontal) B = the LNB down conversion frequency (l=low,

h=high, U=USA) D = decoding type (0=test, 1=DSS-A, 2=DSS-B,

3=DVB)

2.8 Setting the Skew Angle

(European Systems Only)

The Antenna LNB skew angle must be adjusted to optimize channel reception. Refer to your satellite service provider for the proper skew angle for the selected satellite service and geographical location. The ADCU will also provide the skew angle for the installed satellites, as long as a GPS is providing data input to the ADCU or the vessel’s correct latitude and longitude were entered during the satellite installation process. Refer to Section 3.7.1, “Antenna Status Data Screens,” for details on viewing the ADCU-calculated skew value.

Adjusting the LNB Skew Angle

1. Turn off the power to the Antenna Unit.

2. Remove the radome and set it aside.

3. Loosen the two wing screws securing the LNB within the choke feed as illustrated in Figure 2-26.

4. Refer to the LNB skew angle labels on the end of the LNB and on the LNB choke feed (pictured in Figure 2-27) and adjust the LNB as necessary to match as closely as possible the skew angle provided by your service provider or the ADCU.

5. Retighten the wing screws.

2.9 Checking Out the System

To complete the TracVision G4 installation, it will be necessary to verify that the system functions properly. Critical to ensuring that the system is configured and operating properly is to check the system startup routine to ensure that the system is operating within normal parameters.

To do so, it is necessary to connect a PC to the terminal maintenance port. The diagnostics procedure requires terminal emulation software such as PROCOMM, Windows Terminal, or Windows 95/98 Hyperterminal. Use the settings appropriate to your application.

The sensor module housing must be mounted as close to level in pitch and roll as possible, with its long axis parallel to the vessel’s centerline. Sometimes allowances must be made for the particular installation where pitch, roll and azimuth references cannot be met. The offset values adjust for this. The allowable offset values for pitch and roll are ±45˚; the offset for azimuth can be up to ±180˚. Once entered, offset values will not need to be changed unless the Sensor Module is relocated.

3-15

Interface Configuration and Operation

54-0147 Rev. G

Figure 3-20

Entering Gyro Offset Values

Pitch, roll, and yaw settings are determined by the Sensor Module’s internal inclinometer, not external measurements.

To set pitch, roll, and yaw properly, initially enter zeros for all measurements. Choose the Pitch, Roll, and Yaw display from the Main Menu and record those numbers.

Reverse the value of the Pitch and Roll (positive becomes negative, negative becomes positive).

Return to the Gyro Offset menu and enter the recorded numbers.

This process should be carried out in still water or at the dock.

As noted in Section 2.3.2, “Mounting the Sensor Module,” the sensor must be aligned to within ±5˚ of the vessel’s fore-and-aft centerline. Deviation beyond ±5˚ will degrade pitch, roll, and yaw accuracy.

GyroTrac-specific issues (Section 4.2)

LNB assembly faulty (Section 4.4)

Antenna gyro faulty (Section 4.4)

4.1.1 Blown Fuse, Low Power, or Wiring

If the Antenna Unit is installed but entirely non-responsive, there are three key factors to check as part of the troubleshooting process:

1. Blown Fuse – The Antenna Unit is equipped with a fuse mounted on its CPU Board. If this fuse has blown or been broken, the Antenna Unit will not operate. Refer to Section 5.4, “PCB Removal and Replacement,” for details on the fuse location and how to access the CPU Board.

2. Low Power – If the power cable from the Antenna Unit to the power source or ADCU is more than 50 ft (15 m), the power levels can decrease over the course of the cable, resulting in a voltage level at the Antenna Unit that is too low to power the system. Refer to Section 2.4.2, “Providing Power to the Antenna Unit,” for details on supplying adequate power to the Antenna Unit.

3. Wiring – If the system has been improperly wired, it will prevent the Antenna Unit from operating correctly. Refer to Section 2.4.1, “Wiring the Antenna Unit to the GyroTrac ADCU,” for complete system wiring information.

4.1.2 Vessel Turning During Startup

If the vessel turns during the 60-second startup and initialization sequence that occurs immediately after turning on the power to the TracVision G4 unit, the antenna gyro will record that variable motion as “standing still.” This may cause the antenna to track improperly. To solve this problem, turn TracVision G4 off for at least 10 seconds. Turn the system back on, making certain that the vessel is either motionless or travelling in a straight line for the 60 seconds immediately following power-up.

4-2

TracVision G4 Installation and Technical Manual

4.1.3 Incorrect Satellite Configuration

(European Systems Only)

The satellite configuration on European IRDs must match the satellite settings on the TracVision G4 system.

• Satellite A on the TracVision G4 must be the same satellite as IRD Alternative 1 (or A, based on your IRD) and must be assigned the IRD DiSEqC 1 setting.

• Satellite B on the TracVision G4 must be the same satellite as IRD Alternative 2 (or B, based on your IRD) and must be assigned the IRD DiSEqC 2 setting.

4.1.4 Satellite Signal Blocked

Satellite signals can be blocked or degraded by buildings, other vessels, or equipment on the vessel itself. Refer to Section 2.1, “Choosing the Best Location and Getting the Best Reception,” to make certain that the TracVision G4 unit is in the optimal location.

4.1.5 Outside Satellite Coverage Zone

TracVision G4 will provide outstanding reception within the 18" (45 cm) antenna coverage area for your satellite television service of choice. However, signal quality can be degraded as you approach the fringe coverage areas. Refer to your satellite television service manual or an Internet resource, such as www.satcodx.com, to check the viable coverage area for a 18" (45 cm) antenna.

4.1.6 Radar Interference

The energy levels radiated by radar units can overload the antenna front-end circuits. Refer to Section 2.1, “Choosing the Best Location and Getting the Best Reception,” to make certain that the TracVision G4 unit is in the optimal location with regard to your radar unit.

4-3

Troubleshooting

54-0147 Rev. G

Refer to your IRD user manual for complete instructions on configuring your IRD.

4.1.7 Incorrect or Loose RF Connectors

As part of preventive maintenance (described in Section 5, “Maintenance,”) KVH recommends checking the Antenna Unit

cable connections. A loose RF connector can reduce the signal quality. Refer to Section 2.4.8, “Connecting the Antenna RF Signal Cable to the IRD” for directions on proper Antenna Unit to RF cabling.

4.1.8 Multiswitch Interference (DSS Plus™IRD Users Only)

TracVision G4 has the capability to switch from one satellite to another when you choose TV channels that are carried by your two selected satellites. However, some multiswitches (either active or passive), such as the Channel Master model 6214IFD, may interfere with the 22 KHz tone sent by DSS Plus IRDs to the antenna. As a result, the antenna may not receive the signal to change satellites when you change channels using your DSS Plus remote.

In this case, you will need to use the maintenance port satellite switch procedure explained in Section 3.2, “Data Displays and

Accessing the Main Menu.”

4.1.9 Passive Multiswitch Used (North American Systems Only)

As noted in Section 2.4.8.2, “Connecting the Antenna RF Signal Cable to a Multiswitch (North American Systems Only),” using a

passive multiswitch may cause some signal loss and possibly reduce the maximum reception range in fringe areas. An active multiswitch can be used to connect more than two IRDs to the TracVision G4 system. However, please refer to Section 4.1.8, ”Multiswitch Interference,” for an explanation of a potential issue with the use of any type of multiswitch.

4-4

TracVision G4 Installation and Technical Manual

Due to the signal polarization in European satellites, the use of a multiswitch (active or otherwise), will result in a loss of signal and less than optimal operation with TracVision G4 systems used in Europe.

4.2 GyroTrac-specific Issues

The GyroTrac is designed for reliable, easy use. This section provides a brief overview of some potential operational issues that may arise.

Issue 1:

System is installed correctly and power is available, but the system is non-functional.

Check the fuses within the ADCU. Remove the two screws securing the top and the base of the ADCU. Remove the top of the ADCU. The fuses are secured in brackets on the upper and lower printed circuit boards (PCBs) within the unit. Remove the damaged fuse and replace with a new, functional fuse.

Note: The fuse on the lower (main) PCB is a 1-amp fast blow fuse. The fuse on the upper (interface) PCB is a 4-amp fast blow fuse.

Issue 2:

System fails startup routine and ADCU displays “Errors Detected.”

Solution:

GyroTrac will not operate unless the system passes the startup self-tests. The following actions may be taken in this instance.

•

Shut down the system and restore power.

• Shut down the system and verify proper wiring as

detailed in Section 2.4, “Wiring the TracVision G4

System Components.”

• Contact a KVH dealer or distributor for further

assistance.

Issue 3:

GyroTrac is connected to a TracVision G4 system but there is no communication between GyroTrac and the antenna, and you are unable to access antenna-specific menus on the ADCU.

Solution:

Verify that GyroTrac is configured as a TracVision component, as detailed in Section 3.5.5, “Selecting TracVision or GyroTrac-only

Operations.”

Issue 4:

There is no data output through Serial Port #3.

Solution:

Serial Port #3 provides no output when GyroTrac is configured as a component within a GyroTrac-compatible TracVision system.

4.3 IRD Troubleshooting

The IRD that was provided with your satellite television service may also be the cause of less-than-ideal operation. First check the IRD’s configuration to ensure it is set up for the desired programming. In the case of a faulty IRD, refer to your IRD user manual for service and warranty information. If the IRD is both configured properly and fully functional, contact your local KVH dealer or service center for assistance.
