The TracVision G4 uses a state-of-the-art actively stabilized
antenna system. Once the satellite is acquired, the antenna gyro
continuously measures the heading, pitch, and roll of your vessel
and sends commands to the antenna motors to keep the antenna
pointed at the satellite at all times.

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.
TracVision G4’s default satellite
pairs are:
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.

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.
Before you can start watching
satellite TV using your TracVision

TracVision G4 Technical Manual
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.
Figure 2-1
Antenna Blockage
Blocked!
TracVision Antenna
Mast
Vessel Platform
•
•
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 front-
end 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.

TracVision G4 Technical Manual
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 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.
• 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.

2.5 Connecting 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):
For instructions on RF wiring for
TracNet, please refer to the TracNet
Owner’s Manual or Technical
Manual.
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.

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”

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.
Be sure to connect a ground cable
from each IRD to a suitable ground,
ideally the ADCU ground terminal.
If you are using a multiswitch, you can ground the multiswitch instead
of the individual IRDs.

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.
Do NOT connect the antenna data
cable’s drain wire (shield).
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.
The antenna unit’s power cable
connector cannot accept cables
larger than 14 AWG (1.5 mm2).
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.

TracVision G4 Technical Manual
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.
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.
• Data conductor wire should be minimum 18 AWG
(0.75 mm2), twisted pair, stranded, tinned marine
cable.
• Do not use cables with a wire diameter larger than
12 AWG (2.5 mm2), 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.

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)
When the vessel is stationary,
certain GPS models may not output
the data required for GyroTrac to
determine true north.
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.

Installation
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.
Before connecting the power cable,
turn off vessel power and test the
circuit to ensure that no power is
present.
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.
Power supplied to the
TracVision G4 MUST NOT exceed
16 VDC or the TracVision power
supply will suffer serious damage!
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.

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 tie-
wrap on either side of the ferrite.

TracVision G4 Technical Manual
2.7 Calibrating the Sensor
Every sensor module is calibrated at the factory in a perfect-
world 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.
You must calibrate the GyroTrac
sensor after installation so that it
can compensate for any 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.
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.
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.

For guidelines on finding a suitable
location, refer to “Choosing the
Best Location for the GyroTrac
Sensor” on page 14.
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.

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 one-
satellite 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.

2.10 Setting 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.
Figure 2-37
Adjusting the European
LNB Skew Angle
Skew Labels
Figure 2-38
Skew Angle Labels
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.

2.11 Checking 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).

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.

2.12 Changing 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.
Table 2-16
LNB Part Numbers
Part Name
Part Number
02-1278
European-style LNB
North American-style LNB
02-0870
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 the
ADCU” 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.
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.

Entering Gyro Offset Values
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.

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.
Do NOT use this function unless
directed by KVH Technical Support
or a KVH-authorized technician.
Improper data selection may affect
the system’s operation.
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 “Manually
Controlling 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
4.2 Causes 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 to
Vessel 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.

Troubleshooting
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 the
Best 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
For your convenience, KVH
provides links to several web sites
that offer satellite coverage
information. Simply go to our web
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 Location
for 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.

TracVision G4 Technical Manual
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.

Troubleshooting
4.3 GyroTrac-specific Issues
The GyroTrac is designed for reliable, easy use. This section
provides a brief overview of some potential operational issues.
Issue 1:
Figure 4-1
ADCU Fuse Location
(Top Cutaway)
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.”
4-amp Fuse
(Upper PCB)
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.

TracVision G4 Technical Manual
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.
4.4 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.
4.5 Antenna 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.
4.6 Computer 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.

5.10 Preparing for Shipment
If you need to repack the antenna unit for shipment, the shipping
restraints removed during installation must be replaced. Follow
these steps to reinstall the restraints.
1. Rotate the azimuth mechanism slowly to find the
limit switch stop. The front of the antenna should
be facing the forward arrow.
When rotating the azimuth
mechanism by hand, go slowly!
Hitting the mechanical stops with
excessive force will damage the
azimuth limit switch.
2. Rotate the azimuth mechanism 180º in the
opposite direction to ensure that the mechanism is
not resting on the limit switch stop.
3. Insert the two azimuth shipping restraint bolts,
washers, and spacers (removed during
installation) into the rotating plate, as shown in
Figure 5-14. Using a 10 mm wrench, secure the
rotating plate to the metal base.

GyroTrac Data Outputs
Appendix G
GyroTrac Data Outputs
The GyroTrac transmits up to five selectable message types
simultaneously to external navigation devices connected to the
ADCU. One output port is dedicated to the sine/cosine signal
format, one is dedicated to the Furuno AD10S signal format, and
three separate serial ports allow outputs of NMEA 0183, KVH
RS-422, and Cetrek proprietary signal formats. Each of these
message formats is described below. Step-by-step instructions for
selecting desired message outputs is given in Section 3, “Using the
ADCU Interface” on page 59.
G.1 Sine/Cosine Output
Refer to “Connecting the
Sine/Cosine Interface” on page 35
for complete instructions on
properly configuring GyroTrac and
other navigational systems to use
the sine/cosine output.
GyroTrac may be configured to provide either 3-wire or 4-wire
sine/cosine output, but not both. Sine/cosine output message
options are magnetic or true heading and a combination of
reference and swing voltages used to denote the heading value.
The reference and swing voltages are set through the ADCU to
suit the requirements of the device using the data. [Default
reference voltage is 2.5 volts; default swing voltage is 1.67 volts.]
The allowable range for reference and swing voltages is 0 to
6.5 volts in 0.01 volt increments. The sine/cosine output is
commonly used in ComNav, Robertson, and other autopilots.
The maximum current that can be
drawn from the sine/cosine output
is 10 mA.
B&G 4-wire Sine/Cosine
The B&G 4-wire sine/cosine output (also known as “differential
sine/cosine”) is a substitute of the Halcyon® compass. The
reference voltage should be set to 3.5 volts.

TracVision G4 Technical Manual
G.2 Serial Port Outputs
Serial ports #1 and #2 may be individually programmed
to output any of the message formats described on the following
pages. Up to four NMEA 0183 listening devices can be connected
to each of the serial ports. Serial Port #1 also has a pass-through
duplicate port.
NMEA
The NMEA message format conforms to the
NMEA 0183 version 2.20 standard for message
structure.

Stepper Interface
An optional interface unit is available to generate a stepper
output. The stepper interface uses an NMEA HDM or HDT serial
message input to generate the stepper signal format. The stepper
signal replaces traditional gyro outputs used with satellite
communications systems, autopilots, and steering displays. The
Stepper Interface unit is shown in Figure G-1 while the
specifications are listed in Table G-6.
Please refer to the Stepper Interface User Manual for specific
wiring instructions.

Stepper Voltage Converter
A stepper voltage converter (KVH Part Number 19-0089) is
needed when the receiving stepper device uses a reference
voltage greater than the 5 volt maximum available from the
stepper interface. The converter is wired directly between the
stepper interface output and the receiving equipment to provide
the necessary reference voltage. An external 6-70 VDC power
supply is required to provide the necessary voltage to this device.
Figure G-2 on the following page shows the stepper voltage
wiring connections and wiring diagram.

Parser Commands
The TracVision G4 system parser commands are parsed when the
system receives an ASCII carriage return (Hex 0D). An ASCII line
feed (Hex 0A) is permitted but is ignored in any transmitted
command. All system responses are terminated with an ASCII
carriage return followed by a line feed and ending with either an
acknowledge character (ASCII > (Hex 3E)) or a not-acknowledge
character (ASCII ? (Hex 3F)). The parser commands are shown
below in boldface capital letters but they are not case-sensitive. In
most cases, the command is responded to with an echo; that is, if
you type ZAP, for example, and press “ENTER” the response
will be the command you have entered. For other commands, the
response is specific for each command, such as VERSION,
STATUS or HELP.
