TracVision G4 Technical Manual
Satellite Library
Your TracVision G4 includes a pre-programmed satellite library
of North American and European satellite services. When
configuring the TracVision G4, you may choose a pair of satellites
from the library to be active in the system and with your IRD.
For the antenna to track and receive signals from two satellites,
they must be within 10º longitude of each other in orbit. As a
result, certain satellites can be paired only with certain other
satellites. Tables 1-1 and 1-2 list the possible satellite pairs that
may be selected in North America and Europe. If the satellite
service you wish to receive is not listed in the satellite library, you may
add two additional satellites of your choice to the library.
Your TracVision G4 system includes the following components:
Antenna Unit
The antenna unit houses the antenna positioning mechanism, low
noise block (LNB), power supply, and control elements within a
molded ABS radome. Weathertight connectors on the bottom of
the baseplate join the power, signal, and control cabling from
belowdecks units.
GyroTrac
TracVision G4 includes KVH’s GyroTrac digital gyrocompass for
three-axis attitude/heading reference, ensuring superior open
water performance in any sea conditions. GyroTrac can also
operate as a fully functional, stand-alone heading sensor.
GyroTrac includes the following two components:
Sensor Module
The sensor module houses the system’s compass/yaw sensor,
inclinometer, rate gyros, and processing electronics and is
waterproof to a depth of one meter.
Advanced Digital Control Unit (ADCU)
The ADCU is the user interface, providing access to the system
and its functions through an LCD and three soft keys. The ADCU
also serves as the system’s junction box, allowing the system to
use ship’s power, interface with the sensor module, supply and
receive data to/from the TracVision G4 system, and supply and
receive data to/from other shipboard systems.
Integrated Receiver Decoder (IRD)
The IRD (purchased separately) receives satellite signals from the
antenna unit for signal processing and channel selection, and
sends the signals to the TV set for viewing. Please refer to the
user’s manual provided with your selected IRD for complete
operating instructions.

Choosing the Best Location for the TracVision Antenna
There are several factors to consider when choosing the location
for the TracVision antenna.
•Since the TracVision antenna requires a clear view
of the southern sky to receive satellite signals, the
ideal antenna site has an unobstructed view of the
horizon/satellite all around. The less blockage, the
better the system performs.
•Keep the antenna clear of any obstructions above
decks. The antenna requires a 15º to 85º look angle
to receive satellite signals.
•To minimize tracking errors, place the antenna
unit as close as possible to the intersection of the
vessel’s fore-and-aft centerline and midships. The
antenna unit need not be located exactly on the
vessel’s fore-and-aft axis, but its centerline MUST
be parallel to it.
•The mounting surface should be flat and strong
enough to carry the complete assembly (30 lbs/
13.6 kg). To prevent warpage to the antenna
baseplate, 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.
•Be sure to account for the height and base
dimensions (see Figure 2-2 on the following page).

Radar Concerns
The TracVision antenna must be kept out of line with nearby
radars, as their energy levels may overload the antenna’s frontend circuits. In an ideal installation, the antenna is mounted four
feet (1.2 m) above and four feet (1.2 m) away from the radar
(measured from the center of the antenna dome to the center of
the radar).
The best placement for the TracVision antenna is above the radar.
However, if there will be a significant horizontal separation
between the radar and TV dome (i.e., at least 8 to 10 feet (2.5 to
3 m)), the TracVision antenna can be placed below the radar as
there will be little chance of signal blockage.

Antenna Unit Dimensions
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.

Choosing the Best Location for the GyroTrac Sensor
•Ideally, the sensor module should be mounted as
low as possible in the center of the vessel – but
NOT in the bilge.
•The mounting surface should be free of excessive
vibration and flexing.
•Maintain at least four feet (1.3 m) separation
between the sensor module and any magnetized
materials, large ferrous masses, cranes, engines,
derricks, other antennas, cables carrying high
amperage direct current, or battery banks.
•Take extra care when mounting the sensor module
on a steel vessel. Enclose the sensor module in a
fiberglass container and use an aluminum, brass,
plastic, or wood (NOT steel or iron) platform to
position the sensor at least four feet (1.2 m) above
and six feet (1.8 m) away from the steel surface.
•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 you need 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. Be sure to use
stainless steel bolts or nails.
Choosing the Best Location for the ADCU
•The ADCU should be mounted in a dry location,
allowing enough room at the back for connecting
system cables.
•The ADCU should be placed so that the LCD
display is visible and the buttons are accessible.
•The ADCU is not susceptible to magnetic
interference and does not need to be mounted on a
level surface.
54-0147
14
TracVision G4 Technical Manual
If uncertain of the best location
for the sensor module, make a
temporary installation and conduct
a calibration (as described in
Section 2.7, “Calibrating the
Sensor” on page 40
). Any
necessary adjustments to the
sensor location can be made based
on the calibration scores.
2.2Mounting the TracVision
Antenna
1. Make sure that you have chosen a suitable
mounting location based upon the guidelines in
“Choosing the Best Location for the TracVisionAntenna” on page 12.
2. Using the template provided in Appendix B on page 127 or the dimensions shown in Figure 2-3,
lay out the four mounting bolt holes and cable
access hole at the mounting site. Make certain that
the “FWD” arrow is parallel with the vessel’s
centerline and pointed toward the bow.
3. Drill the four
3
⁄8" (10 mm) bolt holes and cut out the
3" (80 mm) diameter cable access hole (following
the layout in Step 2). Smooth the edges of the cable
access hole to protect the cables.
4. Bring the data cable, power cable, and RF cable(s)
from belowdecks up through the cable access hole
in the mounting surface (see Table 2-1 on page 9 todetermine the number of RF cables required).
5. Remove the antenna unit from its shipping carton.
Installation
54-0147

set it aside in a safe place. If you bring the radome
topside, be sure to secure it with a lanyard so that
it does not fall overboard.
7. Remove the foam shipping restraint from the
antenna unit.
8. Using a 10 mm wrench, remove the two azimuth
shipping restraint bolts, washers, and spacers from
the antenna unit, as shown in Figure 2-4.
9. Place the foam seal in position on the mounting
surface with the hole centered over the cable
access cutout. Do not remove the paper backing at
this time. Align the seal with the vessel’s centerline
and the narrow end pointing toward the bow (see
Figure 2-5). Scribe a line all around the seal.

10. Position the baseplate assembly in place over the
mounting holes and cable access, with the
baseplate’s “Forward” arrow (shown in Figure 2-6)
pointing toward the bow. 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.
11. Clean the mounting surface where the foam seal
will be placed. Remove the paper backing from the
foam seal to expose the contact cement, then 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.
12. Connect the data, power, and RF cables from
belowdecks to the baseplate as shown in
Figure 2-7. Turn the power and data cable
connectors down until locked in place; don’t use
excessive force. Connect the RF cable(s) using a
7
⁄16"
wrench, applying 30 pounds of torque. If you
connect more than one RF cable, label both ends of
each RF cable to match its antenna baseplate
connector (RF1 or RF2). Do NOT use teflon gel on
the cable fittings as it reduces signal strength at
higher frequencies.

Option 2 - Mounting the Sensor to a Vertical Surface
1. Choose a mounting location based upon the
guidelines in “Choosing the Best Location for theGyroTrac Sensor” on page 14.
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 2-11 on page 20). The brackets are designed
so that the sensor module may be mounted
perpendicular or parallel to the mounting surface,
as pictured in Figure 2-13.
3. The module must be level with the vessel’s deck.
You may fine-tune this placement using the
ADCU’s 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.
4. When choosing a location for the unit, make
certain that there is sufficient overhead clearance
for both brackets and the sensor module.
5. Using the holes in the vertical sensor bracket as a
template, mark locations for the four mounting
screws. Center punch and drill the four holes with
a
1
⁄8" (3.5 mm) bit.

2.4Mounting the ADCU
Mount the ADCU using either of the following options:
Option 1 - Velcro Fastening on a Horizontal Surface
Option 2 - Flush-mounting
The following sections describe how to mount the sensor for both
of these options.
Option 1 - Velcro Fastening on a Horizontal Surface
1. Choose a location based upon the guidelines in
“Choosing the Best Location for the ADCU” on
page 14.
2. Remove the four squares 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 squares and apply
them to the bottom of the housing at each of the
four corners (see Figure 2-16).
3. Position the four Velcro hook disks where the
ADCU will be mounted. Drill screw holes for the
disks and secure in place with the #4-24 screws
supplied in the kitpack.
4. Press the ADCU firmly into place so that the loop
material engages the hook disks.

2.5Connecting the IRD(s)
For the TracVision system to work, you must connect the
following cables to your satellite TV receiver(s) (IRDs):
•RF Cable
•Ground Wire
Connecting the RF Cable(s)
Each RF cable must be an RG-11 (75 ohms) or RG-6 (75 ohms)
cable fitted with F-type connectors. The RF cable(s) should
already be connected to the antenna baseplate (see Step 12 of
Section 2.2., “Mounting the TracVision Antenna” on page 17). The
following sections explain how to connect the RF cable(s) to your
IRD(s).
To connect the TracVision antenna to your IRD(s), choose one of
the following configurations (based on the number of IRDs you
will connect to the antenna):
Option 1 - Connecting One IRD
Option 2 - Connecting Two IRDs
Option 3 - Connecting Three or More IRDs
(North American systems only)
Option 1 - Connecting One IRD
One end of the RF cable should already be connected to the plug
labeled “RF1” on the base of the TracVision antenna. Connect the
other end of the RF1 cable to the IRD plug labeled “LNB,”
“ANT/SAT,” or “SATELLITE IN.”
Option 2 - Connecting Two IRDs
Two RF cables should already be connected to the plugs labeled
“RF1” and “RF2” on the base of the TracVision antenna. Connect
the other ends of these RF cables to the plug labeled “LNB,”
“ANT/SAT,” or “SATELLITE IN” on the two IRDs.
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.
54-0147

TracVision G4 Technical Manual
For instructions on RF wiring for
TracNet, please refer to the
TracNet
Owner’s Manual
or
Technical
Manual
.
Option 3 - Connecting Three or More IRDs
(North American Systems only)
To connect three or four IRDs to the TracVision antenna, you will
need to install an active multiswitch (Channel Master model
6214IFD or equivalent) between the antenna and the IRDs. Two
RF cables should already be connected to the plugs labeled “RF1”
and “RF2” on the base of the TracVision antenna. Figure 2-18
shows a typical wiring arrangement for three or four IRDs.
Mount the multiswitch unit in accordance with the
manufacturer’s instruction sheet.
1. Connect the RF cable labeled "RF1" to the
multiswitch input labeled "LNB RHCP +13V.”
2. Connect the RF cable labeled “RF2” to the
multiswitch input labeled "LNB LHCP +18V.”
3. Connect the multiswitch outputs to individual IRD
inputs. Use RG-6 cable 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).
Installation
54-0147
27
Figure 2-18
Single Multiswitch Installation
(North American systems only)
The use of an active multiswitch will
interfere with the 22 KHz tone sent
by DIRECTV DSS Plus™IRDs to
the antenna. As a result, the
antenna will not receive the signal
to change satellites when you
change channels using your
DIRECTV DSS Plus remote. You
will need to use the ADCU front
panel buttons to switch between
satellites.
Due to the signal polarization in
European satellites, the use of a
multiswitch will result in a loss of
signal and less than optimal
operation with TracVision G4
systems used in Europe.

Multiple Multiswitch Installation
If you need to connect more than four IRDs to the TracVision
antenna, you may carry out a multiple multiswitch installation,

Connecting the IRD Ground Wire
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 the ADCU ground terminal (route the ground wire to the
ADCU and leave unconnected for now). Each IRD that you connect
to the TracVision system should have a similar ground
connection.
If you are using a multiswitch, you can ground the multiswitch instead
of the individual IRDs.

2.6Wiring the ADCU
All other wiring for the TracVision system connects at the rear
panel of the ADCU. Included in the GyroTrac kitpack are five
terminal strip connectors with terminal connectors numbered 1
through 60 (see Figure 2-20). You will connect all wires to these
terminal strip connectors first, then you will insert the connectors
into the rear panel of the ADCU.
For the TracVision system to work, you must wire the following
cables to the ADCU:
•Antenna Data Cable
•Antenna Power Cable (unless you are connecting
antenna power to its own circuit)
•GyroTrac Sensor Cable
•Vessel Power Cable
•IRD Ground Cable(s)
You may also connect other external devices, such as an
autopilot, plotter, remote display, or GPS, to the ADCU.
Figure 2-21 on the following page shows all available connections
to the ADCU.

Tips for Safe and Successful Wiring
•When inserting a wire into a terminal connector,
make certain that the 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.
•Each cable provided with the TracVision G4
should be routed and dressed before terminating
at the ADCU. The antenna data and power cable
wires may be trimmed to desired length. However,
be sure to cut back the drain wire (shield); do
NOT connect the drain wire to anything.
Connecting the Antenna Data Cable
Connect the antenna data cable to the red and yellow ADCU
terminal strip connectors as shown in Figure 2-22.

Connecting the Antenna Power Cable
For single-switch convenience, the ADCU has been designed to
serve as a junction box between ship’s power and the antenna
unit. Connect the antenna power cable to the red ADCU terminal
strip connector as shown in Figure 2-23.
Alternate Method of Providing Power to the Antenna
(Optional)
Rather than using the ADCU as its power source, the antenna
unit can be connected directly to a separate 5-amp switch and
breaker if such a configuration is more convenient or if the
ADCU is placed more than 50 ft (15 m) from the antenna unit.
For example, this configuration would be preferred if you needed
to be able to turn off the antenna while keeping the GyroTrac
powered on.
If the power 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.
Do NOT connect the antenna to vessel power until all other
wiring is completed. Also, be sure to follow the same power
wiring guidelines provided in “Connecting the ADCU to Vessel
Power” on page 37.

Connecting External Devices to the ADCU
(Optional)
GyroTrac can be integrated with many types of onboard
equipment, including autopilots, radars, remote displays,
plotters, global positioning systems (GPS), and computers. All
connections between the ADCU and external devices are made at
the terminal strip connectors 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
2
), twisted pair, stranded, tinned marine
cable.
•Do not use cables with a wire diameter larger than
12 AWG (2.5 mm
2
), as this is the largest size the
ADCU connector plugs can accept.
•The cable provided with the optional KVH
rotating card display is 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
on page 10.
As noted in Figure 2-21 on page 30, 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.
When the TracVision G4 antenna is connected to the GyroTrac
system, GyroTrac Serial Port 3 will not be able to 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 stand-alone system as described in
“Selecting TracVision or GyroTrac-only Operations” on page 76.
Connecting the Rotating Card Display (Optional)
For complete instructions on properly wiring the optional
rotating card display, refer to Appendix E on page 135.
54-0147

TracVision G4 Technical Manual
If the ADCU is receiving data from
a ship’s gyro, all compass outputs
are automatically configured as
True North and cannot be set to
Magnetic.
Connecting the Sine/Cosine Interface
(Optional)
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 green ADCU terminal strip connector:
Autopilot/Other System WireTerminal Connector
Sine12
Cosine10
Internal Power Ground7
(not chassis ground!)
Reference (INPUT)8 (KVH Output)
DO NOT connect the autopilot or other system to the ADCU reference

reference. Review the user’s manual for the selected equipment.
Installation

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 cause problems.
This section explains how to resolve
most issues.

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 “Setting the Sine/Cosine Data Output” on page 69 until
the voltmeter indicates 0 VDC.
The sine/cosine interface should now operate with optimal
precision.
Connecting GPS for True North Capability
(Optional)
GyroTrac is capable of determining true north that is accurate,
under most conditions, to within ±1º. This capability requires a
GPS data input to the GyroTrac
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 2-27 and the GyroTrac wiring quick
reference guide on the back cover of this manual, GPS interface
cables connect to the blue ADCU terminal strip connector at
terminals 23 and 24. Refer to your GPS user manual for the
correct NMEA data out configuration.

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. Do NOT reapply
power until all system wiring is completed and all terminal
strip connectors are installed on the ADCU rear panel, as
described in “Connecting the Terminal Strip Connectors to the
ADCU” on page 38.
The TracVision G4 system requires an 11-16 VDC power input.
Since it 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 on page 10.
If vessel power fluctuates widely or is noisy, a 12 VDC, 5-amp
AC/DC power supply or a wide-range DC/DC converter power
supply should be installed. Test the voltage and polarity before
making connections to vessel power.
Connect power to the green ADCU terminal strip connector as
shown in Figure 2-28. 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.
Connecting the IRD Ground Wire
If you’ve routed an IRD ground wire to the ADCU (as
recommended in “Connecting the IRD Ground Wire” on page 28),
connect the wire to terminal 2 of the green ADCU terminal strip
connector (see Figure 2-28).

Connecting the Terminal Strip Connectors to the ADCU
Now that you have connected all wires to the terminal strip
connectors, insert the connectors into the ADCU’s rear panel as
shown in Figure 2-29.
Be sure to attach the terminal strip connectors in their correct
positions, as shown in Figure 2-30.

Proper Terminal Strip Order
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 antenna
unit, the GyroTrac, and interfacing
electronics.
Effective Strain Relief for ADCU Terminal Connections
Due to both the potential number of wires that connect to the
rear of the ADCU and the dynamic environment aboard ship, it is
critical that the terminal connections be properly strain-relieved
using tie-wraps (a number of which are included in the GyroTrac
kitpack).
Some things to consider when strain-relieving wires:
•There should be no tension on the wires
connecting to the terminal strips. Removing slack
is important, but the wires should not be taut.
•Leave enough slack in the wires to allow easy
access to the ADCU’s rear panel in case of future
software upgrades.
•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.

2.7Calibrating the Sensor
Every sensor module is calibrated at the factory in a perfectworld environment. However, hard and soft iron effects on your
vessel can distort the local magnetic field, causing errors in the
reported heading. These errors are minimized by mounting the
sensor module in a suitable location and are further removed by
GyroTrac’s autocalibration feature, which compensates for minor
magnetic distortions.
After installing the GyroTrac, you must calibrate the sensor as
described below and achieve a good calibration score to ensure the
highest degree of heading accuracy.
1. Select a calm day and a clear area. Avoid excessive
pitching and rolling, as this can distort the
calibration data.
2. Apply power to the ADCU and note your
approximate heading so that you will know when
you have completed a full circle.
3. Steer your vessel 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.
4. Once you have completed two full circles, your
GyroTrac should be calibrated. Check the
calibration score as described on the following
page.
You must calibrate the GyroTrac
sensor after installation so that it
can compensate for any magnetic
distortions.
The ADCU is equipped with a fuse
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 4.3, “GyroTrac-specific
Issues” on page 97
for instructions
on checking and replacing the fuse.

The Calibration Score
Each calibration results in a calibration score that is stored in the
system’s memory.
Accuracy (ACC)
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.
Magnetic Environment (MAGENV)
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.
Calibration Update Number (CAL #)
The CAL # indicates the number of times the sensor has been
calibrated. It is used primarily to verify whether a new
calibration has been accepted by the system.

2.8Activating/Programming the IRD
Before it can be used, your IRD must be activated and/or
programmed, as described below.
DIRECTV and DISH Network IRD Activation
KVH makes it easy to activate your DIRECTV or EchoStar (DISH
Network) IRD. Just call KVH at 1-888-584-4163 and ask for IRDActivation (Monday - Friday, 8:30 a.m. - 5:00 p.m. EST). For other
options, please refer to the user manual that accompanied your
IRD.
Other IRD Activations
Please refer to the user manual that accompanied your IRD for
activation instructions.
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 your IRD
owner’s manual for specific instructions.
Table 2-8 provides some key data for use when programming
the IRD.
Configuration ItemSetting
Antenna Alternative 1DiSEqC 1
Antenna Alternative 2DiSEqC 2
LNB FrequencyUniversal
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 2.9, “Installing Satellites Using the ADCU” on page 44
provides details on the satellite installation process.
Table 2-8
Key IRD Settings
When programming the IRD with
the antenna configuration data,
make certain that your choices for
Antenna Alternatives 1 and 2 match
those installed as Satellites A and

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
owner’s manual for complete details on this process.
If you use an active multiswitch to
connect three or more IRDs, the
multiswitch will interfere with the
22 KHz tone sent by DIRECTV
DSS Plus™IRDs to the antenna. As
a result, the antenna will not
receive the signal to change
satellites when you change
channels using your DIRECTV DSS
Plus remote.

Programming User-defined Satellites
The TracVision G4 satellite library has the capacity for two userdefined satellites in case you want to track a satellite that is not
currently preprogrammed in the library. User-defined satellites
can only be configured via the ADCU’s maintenance port. To
configure a user satellite, information about the satellite must be
provided, including:
•Satellite name
•Satellite position (longitude)
•Transponder information for each of the following
polarizations/frequencies:
- vertical high
- vertical low
- horizontal high
- horizontal low
OR
- right
- left
•Transponder information includes:
- frequency
- symbol rate
- FEC code
- network ID (in hexadecimal format)
This information can be obtained from your satellite service
provider or from a number of sites on the Internet, such as
www.satcodx.com.
How to tell the difference between
High and Low bands:
High: 11.700 - 12.750 GHz
Low: 10.700 - 11.700 GHz

2.10Setting the Skew Angle
(European Systems Only)
To optimize channel reception, the antenna’s LNB skew angle
must be adjusted. Refer to your satellite service provider for the
proper skew angle for your selected satellite service and
geographical location. You can also find the proper skew angle
from the ADCU, as long as a GPS is providing data to the ADCU
or the vessel’s correct latitude and longitude are entered into the
ADCU. Refer to “Antenna Status Data Screens” on page 80 for
details on viewing the ADCU-calculated skew value.
Adjusting the LNB Skew Angle
1. Turn off the power to the antenna unit.
2. If the radome is not already removed, remove the
radome and set it aside in a safe place.
3. Loosen the two wing screws securing the LNB
within the choke feed as illustrated in Figure 2-37.
4. Refer to the LNB skew angle labels on the end of
the LNB and on the LNB choke feed (shown in
Figure 2-38) 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.
6. Reinstall the radome. Align the three radome
screw holes with the baseplate nut holders, insert
the #10-24 screws and tighten. Install a protective
plastic screw cap over each screw.

2.11Checking Out the System
Now that you’ve installed the TracVision G4, you need to verify
that the system functions properly. Check the system startup
routine to ensure that the system is operating within normal
parameters.
To view the startup routine, connect a PC to the ADCU’s
maintenance port. The diagnostics procedure requires Windows
Hyperterminal (or other terminal emulation software, such as
PROCOMM). Use the settings appropriate to your application.
1. Connect one end of the PC data cable to
the DB9 maintenance port 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.
A sample startup sequence has
been provided in
Appendix F on
page 143
with the typical ranges
and responses for the
TracVision G4 during startup and
operation.
4. After completing the review of the startup and
operational routines, turn on the IRD and television
and check the channels on the selected satellites.
For European systems, check both horizontally and
vertically polarized channels, if possible.
5. When all checks are completed, shut down the
system.
Be certain to fill out and submit the
warranty card to KVH to ensure
that your TracVision G4 is fully
covered under the 2-year parts and
1-year labor warranty.
Installation

2.12Changing Geographic Location
If you move to a different geographic area, you will need to
modify your TracVision G4 system to receive satellite TV signals
in the new location. To begin receiving satellite signals in the new
area, perform the following steps.
Swap LNBs
To receive the proper satellite signals in the new geographic
location, your TracVision antenna must be equipped with the
appropriate LNB for that location. If moving to the U.S., you will
need to install a North American-style LNB; if moving to Europe,
you will need to install a European-style LNB. Table 2-16 lists the
part numbers for ordering these LNB options.
Part NamePart Number
European-style LNB02-1278
North American-style LNB02-0870
With the new part, you will receive a simple instruction sheet for
swapping the LNBs.
Install New Satellites
When you move to a new area, the list of available satellites
changes. If you’re moving to the U.S., you will need to choose a
new satellite pair from the list of available North American
satellites (see Table 2-9). If you’re moving to Europe, you will
need to choose a new satellite pair from the list of available
European satellites (see Table 2-10). For details on installing these
new satellites, refer to Section 2.9, “Installing Satellites Using theADCU” on page 44.
Replace the IRD
In order to receive satellite TV service in your new geographic
location, you will need to purchase an IRD designed for that
location. Refer to your satellite TV service provider for more
information.
Table 2-16
LNB Part Numbers
You may also need to replace your
television when changing
geographic location. In North
America, your TV must support the
NTSC video standard. In Europe,
your TV must support the PAL
video standard.

3 – Using the ADCU
Interface
This section explains how to use all of the ADCU functions. You will use
the ADCU to operate, control, and monitor the TracVision G4 and
GyroTrac.
2. If a GPS receiver is connected, ensure that it has
obtained an accurate position.
3. Apply operating power to the ADCU.
4. Wait while the system conducts a brief self-test
sequence. Test status messages are displayed on
the ADCU for approximately two seconds each.
If the self-testing routine detects faults in any of the first four selftests, the screen pictured in Figure 3-2 is displayed. Operation
halts at this point and the GyroTrac cannot operate. The unit
should be returned to your local authorized KVH dealer,
distributor, or service center.
Figure 3-1
Startup and Self-test Sequence
The absence of valid GPS data is
not a fault; the status message
merely indicates that valid GPS
data is not present and that those
navigation functions that use GPS
inputs are not available.
The GPS must be turned on first for
TracVision G4 to use the GPS
position data during initialization.
When configured as a component of a TracVision system,
GyroTrac conducts a series of startup routines and self-tests to
verify antenna operation. The TracVision self-test status screens
are only displayed when the main data display is set to show the
antenna status information (as described in Section 3.3, “SetupDisplay Mode” on page 67.

Antenna Error Messages
At times, the ADCU will display error messages alerting you to a
specific problem (e.g., you have selected an invalid satellite pair).
There are also two general antenna error messages that are not
related to a specific action.
“Antenna response incorrect” (shown in Figure 3-7) indicates that
the ADCU received an incorrect answer from the antenna in
response to a request. The solution to this error is simply to
repeat your requested operation.
“Antenna not responding” (shown in Figure 3-8) indicates that
no messages are being received from the antenna. This is usually
the result of the antenna not being powered up or the antenna
being disconnected from the ADCU.

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 ±45º; the offset for azimuth can be up to
±180º. Once entered, offset values will not need to be changed
unless the sensor module is relocated.
Using the ADCU Interface
54-0147

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, “Mounting
the GyroTrac Sensor” on page 19,
the sensor must be aligned to
within ±5ºof the vessel’s fore-andaft centerline. Deviation beyond ±5

Updating Satellite Frequency Data
If the antenna is unable to find a satellite, the satellite’s frequency
data may have changed. The Satellite Frequency Scan feature
allows you to update the frequency data of any satellite stored in
the system’s library.
This function should not be used unless directed by KVH
Technical Support or a KVH-authorized technician.
With the desired satellite, band, and polarization selected, the
system will automatically search for the frequency with the
strongest signal. The system will then update that satellite’s
programmed data with the new frequency (and associated
network ID) and store it in the satellite library.
To update the satellite frequency data, follow the steps below:
1. Place your IRD in the satellite signal meter mode.
2. Select the desired satellite on the ADCU. Ensure
the TV signal meter indicates that you have a
strong signal.
If the antenna is unable to find the selected
satellite automatically, you can manually point the
antenna using the Manual mode (see “ManuallyControlling the Antenna” on page 82).
3. Select the desired polarization and band on the
IRD.
4. Do not move the vessel. Your boat must remain
motionless during the entire Satellite Frequency
Scan process.
5. Follow the ADCU menus on the next page. The
scan itself will take a couple of minutes. Once
complete, restart the antenna and ensure the
antenna will track the new frequency.

TracVision G4 Technical Manual
4.2Causes and Remedies for
Common Operational Issues
There are a number of common issues that can affect the
performance of the TracVision G4. The following sections address
these issues and potential solutions.
Blown Fuse, Low Power, or Improper Wiring
Blown Fuse
The antenna unit is equipped with two fuses
mounted on its main printed circuit board (PCB).
The ADCU is equipped with one fuse mounted on
its upper PCB. If any of these fuses has blown or
been broken, the system will not work. For details
on replacing an antenna unit fuse, refer to
Section 5.4, “Replacing the Main PCB and Fuses” on
page 106. For details on replacing the ADCU fuse,refer to Section 4.3, “GyroTrac-specific Issues” on
page 97.
Low Power
If the power cable from the antenna unit to the
power source or ADCU is more than
50 ft (15 m) long, the power level 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 “Connecting the ADCU toVessel Power” on page 37 for details on supplying
adequate power to the antenna unit.
Wiring
If the system has been improperly wired, the
antenna unit will not operate correctly. Refer to
Section 2.6, “Wiring the ADCU” on page 29 for
complete system wiring information.
Vessel Turning During Startup
If the vessel turns during the 60-second startup sequence that
occurs immediately after turning on the power to the
TracVision G4, the antenna gyro will record that variable
motion as “standing still.” This may cause the antenna to track
improperly. To solve this problem, turn the TracVision G4 off
for at least 10 seconds. Turn the system back on, ensuring that
the vessel is either motionless or traveling in a straight line for
the 60 seconds immediately following power-up.
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.
Refer to your IRD user manual for complete instructions on
configuring your IRD.
Satellite Signal Blocked
Satellite signals can be blocked or degraded by buildings, other
vessels, or equipment on the vessel itself. Refer to “Choosing theBest Location for the TracVision Antenna” on page 12 to make certain
that the TracVision G4 antenna unit is in the optimal location.
Simply moving the vessel to clear an external obstruction will
also restore signal quality.
Satellite Coverage Issue
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 to check the viable coverage area for a
18" (45 cm) antenna.
Radar Interference
The energy levels radiated by radar units can overload the
antenna’s front-end circuits. Refer to “Choosing the Best Locationfor the TracVision Antenna” on page 12 to make certain that the
TracVision G4 antenna unit is in the optimal location with regard
to your radar unit.

Satellite Frequency Data Changed
If some channels work, while one or more other channels do not,
or the antenna cannot find the satellite, the selected satellite’s
frequency data may have changed. To update this frequency
data, refer to “Updating Satellite Frequency Data” on page 88.
Incorrect or Loose RF Connectors
As part of preventive maintenance (described in Section 5.2,
“Preventive Maintenance” on page 103) KVH recommends checking
the antenna unit’s cable connections. A loose RF connector can
reduce the signal quality. In addition, if you are unable to switch
satellites using your IRD remote, make sure that your IRD’s RF
cable is connected to the antenna baseplate connector labeled
“RF1” (see Section 2.5, “Connecting the IRD(s) on page 26).
Type of Multiswitch Used
(North American Systems Only)
An active (not passive) multiswitch must always be used to
connect the TracVision G4 system to multiple IRDs. Refer to
Section 2.5, “Connecting the IRD(s)” on page 26 for directions on
proper multiswitch/multiple IRD cabling.

TracVision G4 Technical Manual
4.3GyroTrac-specific Issues
The GyroTrac is designed for reliable, easy use. This section
provides a brief overview of some potential operational issues.
Issue 1:
System is installed correctly and power is available, but the
system is non-functional.
Solution:
Check the 4-amp fuse within the ADCU. Remove the two screws
securing the top and the base of the ADCU, and remove the
ADCU’s top cover. The fuse is secured in brackets on the upper
printed circuit board (PCB). Remove the damaged fuse and
replace with a new, functional fuse.
Issue 2:
System fails the startup routine and the 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, then restore power.
•Shut down the system and verify proper wiring as
detailed in Section 2.6, “Wiring the ADCU” on
page 29.
•Contact a KVH dealer or distributor for further
assistance.
Issue 3:
GyroTrac is connected to a TracVision G4 system but there is no
communications 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 “Selecting TracVision or GyroTrac-only Operations” on
page 76.

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.
4.4IRD 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.
4.5Antenna Gyro and LNB Faults
Section 5, “Maintenance” on page 101 provides detailed instructions
for authorized service personnel who may be required to replace
the TracVision G4 antenna gyro or the LNB.
4.6Computer Diagnostics
TracVision G4 has been designed to provide diagnostic readouts
viewed on a PC having an RS-232 serial communication port. If
you are unable to isolate a system problem, set up for computer
diagnostics as described on the following page. System problems
will most likely be found somewhere through the diagnostic
readouts.
