1 Introduction

1.1 The Digital Satellite System

Your new TracVision 4 satellite antenna is fully compatible with the Digital Video Broadcasting (DVB) satellites, which use the international standard for digital TV transmissions, and with the DIRECTV

DSS satellites. As a result, you will be able to receive

and decode signals from either DIRECTV, The DISH

™

Network, or ExpressVu with the proper programming and hardware (e.g., the Integrated Receiver Decoder [IRD] for your selected service).

TracVision 4’s default satellite setting is to acquire, track, and receive signals from DIRECTV’s DSS 101 satellite. However, TracVision 4’s software is preprogrammed with the satellite locations and transponder information for the following North American satellites:

• DSS 101˚ W • DSS 110˚ W*

• DSS 119˚ W • EchoStar 61˚ W

• EchoStar 110˚ W • EchoStar 118˚ W

• EchoStar 119˚ W • EchoStar 148˚ W

• ExpressVu

* Contact KVH or DIRECTV for complete details on tracking and

receiving signals from DSS 110.

1.2 TracVision 4 System Over view

Your KVH TracVision 4 employs 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 transmits commands to the antenna motors to keep the antenna pointed at the satellite at all times. This active stabilization is enhanced by a conical scan tracking function to detect and lock onto the strongest signal, resulting in the clearest reception possible. System specifications have been provided in Appendix A.

TracVision

To complete your satellite TV system, you will need an Integrated Receiver Decoder (IRD) (a.k.a. “satellite receiver”), and a television set. A desktop or laptop computer is recommended during installation and to conduct diagnostics. The interrelationship of units is illustrated in Figure 1-2.

1.2.1 The TracVision 4 Antenna Unit

The Antenna Unit includes the antenna positioning mechanism, signal front end, power supply, and control elements. A molded ABS radome encloses the baseplate and is secured in place with flat head machine screws. Weathertight connectors located on the underside of the baseplate join the power, signal, and control cabling from below-decks units. A compression seal keeps moisture away from the connectors.

1.2.2 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. The IRD also provides the interface for the user to activate authorization for reception. Please refer to the User’s Manual provided with your selected IRD for complete operating instructions. Multiple IRDs may be connected to the Antenna Unit to provide satellite signals to a number of TV sets.

Below-decks Cable Lengths

The major considerations in locating the below-decks equipment are accessibility and cable lengths between units. Lengths of these cables are as follows:

Cable (Function) KVH Part # Length

Data Cable (IRD to Antenna Unit) 32-0619-50 15 m (50 ft) Power Cable (Power to Antenna Unit) 32-0510-50 15 m (50 ft) RF Cable (Antenna to IRD) 32-0417-50 15 m (50 ft) IRD Ground Wire 32-0583-50 15 m (50 ft)

2-1

Installation

54-0150 Rev. D

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

KVH recommends the use of RG-6 (75 ohms) cable for RF wiring. Use of non-RG-6 (75 ohms) cables will result in degraded performance. The KVH warranty does not cover degraded performance due to improper wiring.

Table 2-2

Lengths of Provided Below-decks Cables

2.1 Choosing the Best Location and Getting the Best Reception

There are several factors to consider when choosing the respective locations of the TracVision 4 antenna unit.

• The ideal antenna site has a clear view of the

horizon/satellite all around.

• Tracking errors will be reduced if the antenna

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

• Place the Antenna Unit as close to the intersection

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

• Keep the antenna out of line with nearby radars,

as their energy levels may overload the antenna front-end circuits. If necessary, position the Antenna Unit so it is at least four feet (1.2 meters) above or below the level of the radar.

• Make sure that the mounting surface is rigid so

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

2.2 Installing the Antenna Unit

Specifics of installation will vary with vessel design but the following procedures are applicable in most situations and will result in a secure and effective installation. Table 2-3 lists the components provided in the Antenna Unit Installation kitpack.

2-2

A Guide to TracVision 4

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.

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

Table 2-3

Antenna Unit Kitpack Contents

Tips for Successful Antenna Unit Placement and Mounting

• The mounting surface should be essentially flat,

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

• The antenna unit need not be located exactly on

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

• Be sure to account for the radome height and the

base dimensions, illustrated in Figures 2-1 and 2-2 respectively.

Antenna Unit Mounting Procedure

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

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

2-3

Installation

54-0150 Rev. D

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

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

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

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

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

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

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

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

9. Place the baseplate over the holes drilled in the foundation. Rotate the azimuth mechanism plate to expose each mounting hole. When rotating the azimuth mechanism by hand, go slowly. Hitting the stops with excessive force will damage the azimuth limit switch.

10. Place a flat washer from the kitpack on a bolt and insert the bolt into its hole from above.

11. Apply a flat washer and lock nut from underneath.

12. Tighten securely until the foam seal is compressed as far as it will go and all four feet are bottomed against the mounting surface, as illustrated in Figure 2-5.

13. Replace the radome over the baseplate. Align the radome screw holes with the nut holders, insert the screws and tighten. Install a protective plastic screw cap from the kitpack over each screw. Several spare protective caps are provided.

2.3 Wiring the TracVision 4 System

A switchplate has been provided to serve as the hub of the TracVision 4 wiring (with the exception of the RF cable, which will be connected to the IRD). This switchplate includes an ON/OFF switch and a DB9 maintenance port for easy access to the Antenna Unit’s software and diagnostics. Follow these steps to begin the wiring process.

1. Select a location to mount the TracVision 4 switchplate. It should be flat and within reach of the cables connected to the Antenna Unit.

2. Create a panel cutout in the mounting surface. Figure 2-6 illustrates the mounting dimensions and a template has been provided in Appendix C.

3. Run the Antenna power and data cables from the Antenna Unit and out through the panel cutout.

4. Run a cable from ship’s power (11-16 Vdc) through the panel cutout.

A Guide to TracVision 4

You are now ready to wire the TracVision 4 system to the switchplate connectors and ship’s power.

Tips for Safe and Successful Wiring

• When attaching cables to the TracVision 4 switchplate connectors, make sure the insulation is stripped back approximately

⁄16". Twist the wires gently to help achieve a good connection. Do not pinch insulation inside the connector.

• After attaching the power and data cables to the appropriate terminal connector strips, tug gently to ensure a firm connection.

2.3.1 Wiring the Antenna Unit Data Cable

Find the TracVision 4 data cable (cable #32-0619-50) where it comes through the panel cutout made earlier. Wire the data cable to the switchplate connectors as indicated in Figure 2-8. The connector board is etched with the same wire color identification to make the wiring process easier.

A comprehensive wiring diagram for the TracVision 4 system has been provided in Appendix D.

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

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

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

2.3.4 IRD Ground Cable

A grounding wire (cable #32-0583-50) has been provided to connect your IRD to a suitable ground and protect the system. 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, such as the ship’s power ground wire connected to the switchplate.

2.3.5 Installing the Switchplate

After completing the switchplate wiring process, you must install the switchplate itself. This process, detailed in the following steps, is illustrated in Figure 2-11.

1. Drill four

⁄32" (4mm) holes in the support frame.

2. Fit the switchplate assembly and support frame into the panel cutout made in Step 2 in Section 2.3 and flush to the mounting surface.

2.4 Selecting the Active Satellite

As noted previously, TracVision 4 can track a variety of DVBcompatible and DSS satellites. The system contains a preprogrammed library of North American satellites. It also has two open slots that you may use to program two additional satellites of your choice. Two of these satellites may be selected to reside in the system’s active memory as Satellites A and B. Once this is done, a simple command via the maintenance port will tell the antenna to track one or the other, making it easy to switch between the satellites of your choice. Table 2-4 provides a grid of possible North American satellite pairs.

The satellites listed in TracVision 4’s preprogrammed satellite library will be sufficient for most North American users. However, if you wish to install one or two user-defined satellites, proceed to Section 2.4.2, “Programming User-defined Satellites.” After configuring the user-defined satellites, return to the satellite installation process in Section 2.4.1, “Installing Your Selected

Satellites.”

2.4.1 Installing Your Selected satellites

When you first connect to the system, it is programmed with the factory default satellite assignment: DIRECTV’s DSS 101 satellite. Should you wish to track a different satellite (either from the satellite library or a user-defined satellite), you must instruct the antenna which satellite will be the active satellite of choice.

Connecting to the TracVision 4 Maintenance Port

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

1. Connect one end of the PC cable to the DB9 connector on the switchplate. 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 4 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.

2-12

A Guide to TracVision 4

Figure 2-14

PC DB9 Connector

Installing the Satellite of Choice

Once the data connection has been made between the PC and the TracVision 4, you must assign the satellites you wish to have in the satellite pair. On the maintenance screen, put the antenna in Idle Mode by typing

HALT, then enter the SATINSTALL command:

Command: SATINSTALL,<sat_a_name>,<sat_b_name><cr> Where: <sat_a_name> = the name of your choice for

Satellite A

<sat_b_name> = the name of your choice for

Satellite B

Table 2-5 lists the assigned names for satellites that are in the preprogrammed North American satellite library. If you do not wish to assign a pair of satellites, enter

None as the name of

Satellite B.

After you have assigned satellites as Satellites A and B, the final step is to tell the antenna which of the two satellites it should acquire and track. To do so, enter the Satellite Selection parser command as follows:

Command: @L,x<cr> Where: x = Aor B (one of your selected satellites as

defined during the SATINSTALL process)

Choosing A or B will assign the antenna to acquire and track that installed satellite. To complete the process, type

ZAP<cr> to

restart the system.

2.4.2 Programming User-defined Satellites

The TracVision 4 satellite library has two open slots that you may use to program two user-defined satellites in case you want to install/watch a satellite that is not in the KVH predefined list. To configure a user satellite, the system must first be in Idle Mode (by typing

HALT) and then information about the satellite must

be provided, including:

• Satellite name

• Satellite position (longitude)

Entering User-defined Satellite Data

Once the link between the PC and the TracVision 4 is established as described in Section 2.4, “Selecting the Active Satellite,” it is necessary to provide initial longitude data regarding the userdefined satellite. To do so, enter the SATCONFIG parser command via PC as follows:

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

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

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

Function: configures one of the user-configurable satellites

with the longitude provided

Response: if valid entry, echoes the input data

if invalid entry, returns error message

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

@DEBUGON.

2-14

A Guide to TracVision 4

Following the entry of the SATCONFIG and DEBUGON commands, enter the satellite transponder information via PC as follows:

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

Where: @SATCONFIG = directs data to the RF Board

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

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

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

Mbit/second (01000 - 30000) C = the FEC code (e.g., 12, 23, 34, 56, 67, 78) ID = the satellite network ID in hexidecimal format

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

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

3=DVB)

This information has to be entered for each of the four transponder categories:

• vertical high • vertical low

• horizontal high • horizontal low

TracVision 4 requires that the data fields for all four transponder categories be provided. If the selected satellite does not have information for one or more of the transponder categories, default information should be entered in the fields as follows:

Transponder Data Default Value

Frequency 00000 Symbol Rate 27500 FEC Code the same value as provided for those

transponders with data Network ID 0x0000 Polarity and Band whichever combinations are not

already provided

Installation

54-0150 Rev. D

After entering this information, it is necessary to save these settings. To do so, type:

@SAVE,A (or B if this data is for Satellite 2) @DEBUGOFF

After completing this process, restart the system by either cycling

power or typing

ZAP in the maintenance screen.

One of your user-defined satellite options has now been added to the TracVision 4 satellite library. This option will now be available the next time the SATINSTALL command is given.

An Example of Configuring a User-defined Satellite

The following is an example of configuring the fictional YOURSAT 101 as the USER1 configured satellite. Prior to configuring this satellite or any others, be certain to get the most up-to-date information from one of the sources previously discussed.

2.5 Checking Out the System

To complete the TracVision 4 installation, it will be necessary to verify that the system functions properly. Critical to ensuring that the system is configured and operating properly is to check the system startup routine to ensure that the system is operating within normal parameters.

1. Connect a PC to the maintenance port and startup the system as instructed in Section 2.4, “Selecting

the Active Satellite.”

2. Allow the system to fully initialize. Review the startup data and make sure that no system errors have been reported. A representative startup sequence has been provided in Appendix F.

4. After completing the review of the startup and operational routines, shut down the system.

Completing the Installation Process

1. Refer to your satellite programming guide. Select several channels from your active satellite service to confirm that the system is receiving and decoding the signals properly.

2. Fill out and submit the warranty card to KVH.

Installation

54-0150 Rev. D

3 Antenna Unit Operation

The TracVision 4 system is easy to use. Antenna Unit initialization and satellite acquisition is automatic and does not require operator intervention.

To start up the TracVision 4 system:

1. Turn on the IRD and the television receiver.

2. Turn on the Antenna Unit.

Refer to your IRD user manual for complete operating instructions for the IRD.

Tips to Get the Best Reception with TracVision 4

• A clear line of sight to the satellite is required to

ensure that the antenna can acquire and track the satellite.

• The Antenna Unit is designed to rotate a full 720°

before coming to the end of its cable. If it does so, the system conducts an automated cable unwrap. This involves rotating the dish in the opposite direction. During this process, your television transmission will be frozen momentarily while the cable unwraps and the antenna reacquires the satellite.

Automated Operations

The system carries out a number of automated steps at startup. For reference, these steps are:

1. Antenna Unit Initialization – The microprocessor circuitry does a basic self-test of the hardware and software associated with the antenna unit.

2. Satellite Search Modes – The system loads the previously stored satellite location. If there is no previously stored satellite location (as with a new installation), a default position is loaded. The system then begins a set of Search Modes to find the satellite. The default position may be modified via the maintenance port.

3-1

Antenna Unit Operation

54-0150 Rev. D

To minimize the time it takes the antenna to acquire the satellite, do not change the channel during the startup process or cable unwrap.

3. Fine-tuning/Satellite – When a signal is detected, the antenna interrupts the search mode and begins a procedure to fine-tune the position for maximum signal strength. When the signal peak is found, the RF circuitry verifies the ID of the acquired satellite. If the ID is correct, the system enters tracking mode; if it is wrong, it resumes the search. Once the satellite has been acquired, the system updates the satellite location stored in memory.

3.1 Watching Your Selected Satellites

TracVision 4 can have a pair of satellites installed, either one of which can be the active satellite selection. There are several methods to select whether your TracVision 4 will track Satellite A or B based upon your location and selected satellite service.

Maintenance Port Switch

As described in Section 2.4, “Selecting the Active Satellite,” the maintenance port is used to tell the Antenna Unit which satellite it should acquire and track. To make the antenna track either Satellite A or B, first connect the PC to the maintenance port as described in Section 2.4. Once the data connection is made, enter the Satellite Selection parser command as follows:

Command: @L,x<cr> Where: x = Aor B (one of your selected satellites as

defined during the SATINSTALL process)

Choosing A or B will assign the antenna to acquire and track that installed satellite.

DIRECTV Satellite Subscribers

DIRECTV subscribers in certain regions of the United States will require a DSS Plus

™

IRD to receive both satellite and local channels. Check with DIRECTV for regional requirements. The DSS Plus IRD allows you to switch channels using the remote control. If you are a DIRECTV subscriber, but do not have a DSS Plus IRD, use the maintenance port switching option previously described.

EchoStar and Expressvu Satellite Subscribers

EchoStar and Expressvu subscribers will need to use the maintenance port switching method.

3.1.1 Watching TV Underway and at Rest

TracVision 4 is designed to operate as efficiently and as reliably as possible both when your vessel is underway and at rest (e.g., at the dock).

“Instant On” Operation

As part of its operation, TracVision 4 routinely saves the satellite position to memory and retains it when the system is turned off. When TracVision 4 is powered up, the system looks at the satellite’s last saved position. If the vessel has not changed its location, the antenna will immediately acquire the satellite and receive the signal without initializing the antenna.

If the antenna has acquired the satellite through the “Instant On” feature, then once the vessel begins to move, the Antenna Unit will quickly carry out its normal initialization routine to prepare for active tracking, resulting in a brief (~30 seconds) freeze in the satellite signal and image. As soon as initialization is complete, satellite tracking will resume and the television image will be restored.

Conical Scan Tracking While Underway

The antenna control unit generates a conical scanning function to maintain peak signal strength to the receiver and to update the satellite’s position. When conical scan tracking is active, the antenna moves continually with a circular motion to sweep across the satellite’s peak signal. The signal strength is then fed back to the control circuits to keep coming back to the direction of the strongest signal. If the satellite signal is lost while the system is in conical scan track mode, the control software imposes a 30-second time-out delay. If the signal is not regained during that time, the antenna reverts to the set of Search Modes to start looking for the satellite signal. This is an automatic process that does not require user intervention.

3-3

Antenna Unit Operation

54-0150 Rev. D

Sleep Mode

When the vessel has come to a stop and holds its position for any extended period of time, the Antenna Unit enters Sleep Mode, which turns off the conical scan tracking thereby reducing any motor noise the antenna may be making. As soon as the vessel moves, Sleep Mode will automatically be turned off and the system will begin tracking the satellite again.

LNB assembly faulty (Section 4.3)

4.1.1 Blown Fuse, Low Power, or Wiring

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

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

2. Low Power – If the power cable from the Antenna Unit to the power source is more than 15 m (50 ft), the power levels can decrease over the course of the cable, resulting in a voltage level at the Antenna Unit that is too low to power the system. Refer to Section 2.3.3, “Connecting to Ship’s Power,” for details on supplying adequate power to the Antenna Unit.

3. Wiring – If the system has been improperly wired, it will prevent the Antenna Unit from operating correctly. Refer to Section 2.3, “Wiring the TracVision 4 System,” for complete system wiring information.

4.1.2 Satellite Signal Blocked

Satellite signals can be blocked or degraded by buildings, other vessels, or equipment on the vessel itself. Refer to Section 2.1, “Choosing the Best Location and Getting the Best Reception,” to make certain that the TracVision 4 unit is in the optimal location.

4.1.3 Outside Satellite Coverage Zone

TracVision 4 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.

4-2

A Guide to TracVision 4

4.1.4 Radar Interference

The energy levels radiated by radar units can overload the antenna front-end circuits. Refer to Section 2.1, “Choosing the Best Location and Getting the Best Reception,” to make certain that the TracVision 4 unit is in the optimal location with regard to your radar unit.

4.1.5 Vessel Turning During Startup

If the vessel turns during the 60-second startup and initialization sequence that occurs immediately after turning on the power to the TracVision 4 unit, the antenna gyro will record that variable motion as “standing still.” This may cause the antenna to track improperly. To solve this problem, turn TracVision 4 off for at least 10 seconds. Turn the system back on, making certain that the vessel is either motionless or travelling in a straight line for the 60 seconds immediately following power-up.

4.1.6 Incorrect or Loose RF Connectors

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

cable connections. A loose RF connector can reduce the signal quality. Refer to Section 2.3.5, “Connecting the Antenna RF Signal Cable to the IRD” for directions on proper Antenna Unit to RF cabling.

4.1.7 Using a Passive Multiswitch

An active multiswitch must always be used to connect the TracVision 4 system to multiple IRDs. Refer to Section 2.3.5, “Connecting the Antenna RF Signal Cable to the IRD” for directions on proper multiswitch/multiple IRD cabling.

Appendix E EchoStar Commissioning

Procedure

If you have purchased a DISH Network system, there is a chance that your EchoStar IRD will fail to acquire the satellite when you first activate it. This has been known to happen in IRDs that have not been commissioned within several months of their manufacture. The following process is a manual method of acquiring the satellite for the first time so that the IRD can download the most up-to-date satellite and programming data, allowing it to automatically acquire the satellite from then on.

Please refer to your EchoStar IRD user manual for complete instructions on the IRD, the remote control, and the command screens.

Manual Satellite Acquisition and IRD Commissioning

1. Turn on TV and EchoStar IRD.

2. Using EchoStar remote, press MENU.

- The Main Menu will come up on the Screen.

3. Select #6, System Setup.

4. Select #1, Installation.

5. Select #1, Point Dish/Signal.

- The Signal Strength Screen will appear.

6. Using remote, select the zip code box on the screen, and input the local zip code.

- The screen will show you the Azimuth and

Elevation to the satellite. Write this down.

7. Connect a PC to the data port.

10. Type in the elevation that you obtained in step 6.

- Type

EL,xxx<CR>.

(e.g., Elevation of 30.2° = EL,302<CR>)

11. Using a compass, take a bearing on an object that is approximately on the azimuth obtained in step 6.

12. Type in an azimuth that points the antenna in the direction of the object selected in step 11.

- Type

AZ,xxxx<CR>.

(e.g., Azimuth of 233° = AZ,2330<CR>)

- Valid azimuth range is 0-360° (0000-3600)

13. Check to see if there is signal strength on the Signal Meter Screen.

14. Move antenna counter-clockwise in 5° increments, until signal strength is acquired. If you do not find satellite, point the antenna at the object selected in step 11 and move antenna clockwise in 5° increments until signal strength is acquired.

15. Once satellite is found, fine tune azimuth in 1° increments for maximum signal strength.

16. Fine tune in elevation in 1° increments for maximum signal strength.

17. Once the satellite is found, turn the EchoStar IRD off, using the power button on the infrared remote. Do not turn off the IRD using the front panel. Leave IRD in standby mode for approximately 5 minutes. The IRD will now download new software from the satellite.

18. To verify that the IRD has been updated, put the IRD into the Signal Strength Screen mode, and three satellite options will appear on the left side of the screen: 61.5° West, 119° West, 148° West. Your EchoStar IRD is now updated.

Appendix G Maintenance Port Parser Commands

TracVision 4 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

Serial Communications, Status/Polarization Report,Tone Changes

Function: start serial communications, reports status &

polarization/tone changes Command: @S Response: S,s,p,b,m <cr> every 5 seconds until ><cr>is

returned from system software Where: s = Satellite (a = Primary, b = Secondary)

p = Polarization (v = Vertical, h = Horizontal, x = No LNB Power) b = Band (h = High Band, l = Low band, u = USA) m = Mode (v = Valid, i = Invalid)*

* The Mode bit is used to evaluate the Satellite, Polarization, & Band combination vs. the Frequency/Symbol Rate/FEC currently in RAM. This bit will be set to invalid if the Frequency for the selected combination is set to 0x0000; otherwise it will be set to valid. For example the Mode bit will be set to invalid when the frequency is set to 00000 to indicate that there is not a frequency to track for the LNB tone and voltage setting.

Report RF Tracking Parameters

Function: reports all RF tracking parameters for primary &

secondary satellites* Command: @SATCONFIG Response: F,x,fffff,S,C,ID,P,B,D <cr> Where: x = Satellite (a = Primary, b = Secondary)

fffff = Frequency in MHz (00000 and 10700 to

12700) S = Symbol rate in Mbit/Sec (1000 to 30000) C = FEC code rate (valid rates = 12, 23, 34, 56,

67, 78)

ID = Satellite Network ID in hexidecimal format

(valid range = 0x0000 to 0xffff hex) P = LNB Polarization (v = Vertical, h = Horizontal) B = the LNB down conversion frequency (l=low,

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

3=DVB)

* This command dumps all eight combinations of the Satellite /Freq/Sym/FEC/ID/POL/Band currently stored in RAM.
