Chapter 1 - Introduction
TracVision M3/M2 System Overview
Your TracVision M3/M2 system is a state-of-the-art, actively
stabilized antenna system that delivers live satellite TV to your
vessel’s audio/video entertainment system. A basic system is
illustrated below. A receiver wiring diagram is provided in
Appendix A on page 59.
Figure 1 TracVision M3/M2 System Diagram
The antenna uses integrated DVB technology to
quickly acquire and track the correct satellite,
switch between satellites, and send TV signals to
the interface box. The TracVision M2 acquires and
tracks the satellite while the vessel is moored,
either at the dock or at anchor. The TracVision M3
adds the capability to track the satellite while the
vessel is underway – its gyros keep the antenna
pointed at the satellite at all times.
The interface box allows you to set up and
control the system using its four
pushbuttons and LCD display. It also
supplies power to the antenna and delivers
satellite TV signals to your satellite TV receiver.

Chapter 1 - Introduction
Linear Satellite Signals
Your TracVision system is configured to receive linearly polarized
satellite signals. Satellites around the world (with the exception of
satellites in North America, which transmit circularly polarized
signals) transmit linear signals in vertical and horizontal “waves” that
are offset exactly 90º from each other. This orientation doubles the
bandwidth, allowing the satellite to deliver hundreds of channels of
digital entertainment to your vessel.
Figure 2 Linearly Polarized Satellite Signals
LNB Skew Angle
Since linear satellite signals are oriented in a precise cross pattern, the
TracVision antenna’s receiving element, called an LNB (low-noise
block) must be oriented in the same way to optimize reception. This
orientation adjustment is referred to as the LNB’s “skew angle.” The
figure below illustrates how skew determines the amount of signal the
LNB collects. The more signal, the better the reception.
Figure 3 How Skew Works
Ideal SkewGood SkewBad Skew
= Satellite Signal = LNB "Signal Collector"
TracVision M3/M2 User’s Guide

Chapter 1 - Introduction
The correct skew setting varies depending on your geographic
location, since the orientation of your antenna to the satellite changes
as you move. For example, as shown in the figure below, if your
antenna is tracking the PAS 9 satellite for Sky Mexico programming,
the ideal skew setting ranges from +30 to +70, depending upon where
you’re located within the satellite’s coverage area.
Figure 4 Approximate Skew Settings for the PAS 9 Satellite
For complete details about adjusting the LNB’s skew, see “Setting the
LNB Skew Angle” on page 31.

Chapter 2 - Operation
Receiving Satellite TV Signals
Television satellites are located in fixed positions above the Earth’s
equator and beam TV signals down to certain regions of the planet
(not worldwide). To receive TV signals from a satellite, you must be
located within that satellite’s unique coverage area.
TIP: For your convenience, KVH provides links to several web sites that offer
satellite coverage information. Simply visit our web site at www.kvh.com/
footprint.
Figure 5 Location of Astra1 Satellite
In addition, since TV satellites are located above the equator, the
TracVision antenna must have a clear view of the sky to receive
satellite TV signals. Anything that stands between the antenna and the
satellite can block the signal, resulting in lost reception. Common
causes of blockage include trees, buildings, and bridges. Heavy rain,
ice, or snow may also temporarily interrupt satellite signals.

Setting the LNB Skew Angle
To optimize reception, the antenna’s LNB (low-noise block) must be
set to the correct skew angle for the satellite(s) you want to track.
Follow the steps below to set the antenna’s LNB skew angle.
1. First determine what the correct skew angle should be
for your selected satellite(s) and position. You can find
the correct skew angle by either reading the system
startup screens (see “System Startup” on page 13) or
running the Diagnostics test (see “Running the
Diagnostics Test” on page 42).
Check the reported latitude/longitude as well. If the
interface box reports a latitude/longitude that is more
than 600 km (400 mi) away from your vessel’s actual
position, you should re-enter your position into the
interface box to obtain a more accurate skew angle. See
“Entering Latitude/Longitude” on page 22.

Chapter 5 - Troubleshooting
Five Simple Checks
If you are experiencing a problem receiving satellite TV with your
TracVision system, first check the five simple things below. If none of
these are the problem, check the status lights on the interface box and/
or perform a diagnostics test, as explained later in this chapter.
TIP: You can also try resetting the satellite TV receiver. Turn off and unplug
the receiver, wait one minute, then plug it back in and turn it back on.
Can the antenna see the satellite?
The antenna requires an unobstructed view of the sky to receive
satellite TV signals. Common causes of blockage include trees,
buildings, bridges, mountains, and equipment on the vessel itself.
Is there excessive dirt or moisture on the antenna dome?
Dirt buildup or moisture on the dome can reduce satellite reception.
Clean the exterior of the dome periodically.
Is it raining heavily?
Heavy rain or snow can weaken satellite TV signals. Reception should
improve once the inclement weather subsides.
Is everything turned on and connected properly?
Make sure the power switch on the front of the interface box is turned
on (the VOLTAGE light on the front of the interface box should be lit
green). Also make sure your TV and receiver are both turned on and
set up for the satellite input. Finally, check the cables connecting all of
these components to ensure none have come loose.
Is the antenna’s LNB set to the correct skew angle?
To optimize reception, the antenna’s LNB needs to be set to the correct
skew angle for the satellite(s) you want to track. See “Setting the LNB
Skew Angle” on page 31 for details.

Calibrating the Gyros
The TracVision antenna’s gyros continuously measure the motion of
your vessel and send this data to the antenna’s motor control circuitry
to keep the antenna pointed at the satellite. At the factory, each
antenna gyro is precisely calibrated to work with the antenna’s circuit
board. Therefore, if you ever replace a gyro or circuit board in your
antenna, you will need to recalibrate the gyros for the new part.
Follow the steps below to calibrate the gyros.
1. Press MENUS until the display shows
“DIAGNOSTICS.”
2. Press CHANGE until the display shows
“DIAGNOSTICS= YES.”
3. Press ACCEPT to enter the Diagnostics menu.
Calibrate the gyros only if directed by KVH Technical Support, and
only while the vessel is stationary. A poor gyro calibration can
reduce the performance of the antenna.

Changing Tracking Parameters
On rare occasions, a satellite service provider may change the
configuration of one of its satellites. Since your TracVision antenna
identifies a satellite based on the configuration data it has stored in
memory, the antenna will no longer be able to track the satellite if its
configuration changes. For this reason, the interface box allows you to
change any satellite parameter stored in the antenna’s memory.
Follow the steps below to change a tracking parameter for an installed
satellite.
1. Press MENUS until the display shows
“DIAGNOSTICS.”
2. Press CHANGE until the display shows
“DIAGNOSTICS= YES.”
3. Press ACCEPT to enter the Diagnostics menu.
Change tracking parameters only if directed by KVH Technical
Support. An incorrect tracking parameter can significantly reduce
the performance of the antenna.

Product Care
Please consider the following antenna care guidelines to maintain
peak performance.
• Periodically wash the exterior of the antenna dome with fresh
water and mild detergent. Avoid harsh cleansers and volatile
solvents (such as acetone) and do not spray the dome directly with
high-pressure water.
• If you wish to paint the dome, use only non-metallic automotive
paint without a primer coat. Any paint that contains metal will
block satellite signals and impair reception.

To program your user-defined satellite(s), you first need to connect a
Windows
®
laptop computer to the TracVision system and start
Windows HyperTerminal.
TIP: If you are a KVH-authorized technician, you can use the KVH Flash
Update Wizard instead of HyperTerminal. Enter commands in the wizard’s
“Antenna Comms” window. You do not need to flash the antenna to enter
commands.
1. Turn off the TracVision antenna.
2. Using a PC serial data cable, connect your laptop to the
DB9 Maintenance port on the back of the interface box.
NOTE: If your computer does not have a DB9 serial COM port, you
can use the USB-to-RS232 adapter manufactured by IOGear
(IOGear part number GUC232A). As an alternative, you can also
use the adapter manufactured by Belkin (Belkin part number F5U109
or F5U409).
