CHAPTER 1 - INTRODUCTION
CenterLine is an economical lightbar guidance system that is controlled by a wireless remote. CenterLine provides accurate Straight-Line and Curved Guidance for use in spraying, seeding, and other
related jobs at a cost that rivals foam markers. The CenterLine product is equipped with a combination Beacon/WAAS or WAAS only DGPS receiver, providing sub-meter, pass-to-pass positioning
accuracy. The wireless remote control is used to configure and operate the system through menus
and options displayed on the lightbar.
CenterLine’s attractive design combines compact size with fully adjustable, easy to see LEDs. Using
dedicated buttons on the wireless remote, the lightbar can be dimmed to efficiently run at night and
brightened for viewing in full sunlight.
STRAIGHT OR CURVED GUIDANCE
CenterLine guides along various types of swaths with sub-meter, pass-to-pass accuracy. Select the
driving pattern and CenterLine determines the closest swath to follow. There is no need to decide a
guidance pattern ahead of time or commit to a pattern for the entire job. CenterLine allows the
switching of patterns during operation, determining when a new pattern is being used and keeping
the operator informed of the current status.
WIRELESS REMOTE CONTROL UNIT
CenterLine’s ergonomic, handheld remote control is easier to use than most television remotes.
Seven easy-to-read buttons allow for the scrolling of menus displayed on the lightbar. The remote
keypad is backlit for nighttime operation. Three AAA batteries (included) power the unit for an entire
season.
The small, powerful remote permits mounting the weather-resistant lightbar outside on the hood or in
the cab. When mounted outside, wireless communication permits easy operation while the cab stays
clean and sealed from dust and contaminants.
LIGHTBAR DISPLAY
A text display on the lightbar reports a choice of guidance information. It also warns when an area of
the field is entered that has already been applied. Guidance text information can be turned off, if preferred. Two of the following guidance messages are available for selection during operation to monitor progress:
• Cross-Track Error
• Current Swath Number
• Vehicle Speed
• Applied Area
• Vehicle Course On Ground (COG)
MENU ITEMS AND PICK LIST TEXT
Throughout this User’s Guide, menu item text is d isplaye d between < > characters (i.e., < START>).
Buttons on the remote control are denoted in italics (i.e., Arrow buttons) and will be displayed in th e
margin of the User’s Guide.
Most of the figures in this guide are menu items that are displayed in the text window of the lightbar.
This text represents either a menu item, such as <GUIDANCE>, or a list item, such as <METRIC>.

System
There are two additional menu items that are located in almost every menu:
•<NEXT>
• <TO START>
Figure 1-3 illustrates the <NEXT> and <TO START> menu items in the System Setup menu list.
Pressing the Enter button when <NEXT> is displayed will launch the next menu heading. For example, during Lightbar Setup, pressing Enter at <NEXT> will launch <SYSTEM>. Once in System
Setup, pressing the Escape (ESC) button at <NEXT> will launch the <LIGHTBAR> menu again.
Selecting <TO START> automatically reverts the operator back to the main menu. This is useful
when it is necessary to make only minor modifications and quickly resume operation.

Switching Guidance Modes
Switching guidance modes may be desirable at some point during operation. Typically an operator
makes one or more passes around a field’s headland area during Headland Guidance. While driving
in Headland Guidance, the operator may mark Points A and B to establish guidelines for switching
modes at a later time. Once the headlands are completed, the operator can easily switch to StraightLine Guidance or Curved AB Guidance and complete the field.
To switch between guidance modes, use the Arrow buttons to scroll through the menu until <HEADLAND>, <STRAIGHT>, or <CURVE AB> appears on the lightbar. Select the appropriate guidance
mode and press the Enter button.
A+ Feature
At any time after a guideline is created, the guidance line can be shifted to the current position by
activating the A+ feature. The heading (and shape, if in curved mode) of the original guidel ine is
maintained, but the A-B line is shifted to the vehicle’s current location. Scroll through the operation
menu using the Arrow buttons until <A+> is displayed on the lightbar. Press the Enter button to activate the shift.

Figure 3-3: A+ Feature
Area Determination
The area of the current job or field is important. CenterLine allows the determination of the area of a
field by driving the perimeter. This can be accomplished while driving the first headland circuit during
Headland Guidance.
To determine the area of the field, use the Arrow buttons on the operation menu to locate <AREA>.
Press the Enter button. The lightbar will display <LEFT> or <RIGHT>. Use the Arrow buttons to
select the side of the swath or implement that is the closest to the field boundary. Press the Enter
button to begin area calculation. The lightba r will display < MAP BND> or <MAP BND >. Once the
boundary is ready to be closed, scroll through the operation menu using the Arrow button until
<CLOSE> is displayed. Press the Enter button to close the boundary and determine the area.
Pressing Enter at <CLOSE> will insert a line between the starting location and the current locatio n
and will use the shape to determine the area.
The area will automatically be determined when the vehi cle drives within 15 feet / 4.5 meters o f the
starting point. The bounded area is displayed on the lightbar as a part of the guidance message
stream for three minutes when stopped in an “applied” area. If a bounded area has already been
determined, the <VIEW> menu item will be available. Pressing the Enter button at the <VIEW>
option will display the current bounded area value.

Return To Point
CenterLine allows the operator to mark a point of reference in the field in which to return at a later
time. Typically the Return to Point feature is used to mark a location when stopping guidance and
starting in the same location and direction at a later date and time. This Return to Point locatio n is
stored in the field’s trajectory data and is lost if <NEW?> is select. It is retained if <RESUME?> is
selected.
There is a specific Return to Point button located on the re mote cont rol. The button works in toggle
fashion. Pressed once, the lightbar will display < >. Pressed again, it will navigate back to the
point. The navigation process can be stopped by pressing the Esc button. Once Return to Point is
pressed again (a third time), the old locati on is re pl a c e d wi t h th e ve hi cl e ’s current location.
While operating in Return to Point mode, no active text messages are displayed except error messages. If the vehicle enters an area that has already been applied, the display will alternate between
the Return to Point distance and <APPLIED>.
HEADLAND GUIDANCE
Headland Guidance is used when the operator wants to drive several circuits around the field
boundary and be guided around all circuits that occur after. Headland Guidance is also used when
the operator wants to apply product on a terraced field. Once several headland circuits have been
completed, the operator has the option of switching to Straight-Line or Curved AB Guidance. In the
Headland Curved Guidance pattern, the operator can n avigate to any previou sly applied swath and
be guided parallel to the swath by the X-Track guidance display.
To select Headland Guidance, use the Arrow buttons on the operation menu to location <HEADLAND>. If <HEADLAND> is not displayed in reverse video (the lig htbar is red and “Headland” is
black), press the Enter button. The guidance pattern will be switched to Headland Guidance. If
<HEADLAND> is displayed in reverse video, the system is already in Headland Guidance mode.
Figure 3-5: Example of Headland Guidance
30 Chapter 3 - Operation
Reference Guideline
While operating in Headland Guidance, the operator h as the option to mark Points A and B on th e
reference guideline used for Straight-Line or Curved AB Guidance modes. It is easier to mark Points
A and B for the Straight-Line or Curved AB Guidance modes while driving along a straight edge of a
field. Refer to CHAPTER 3 - CURVED AB GUIDANCE for additional information.
The operator will remain in Headland Guidance until the guidance mode is changed using the operation menu (refer to CHAPTER 3 - SWITCHING GUIDANCE MODES for additional information).
The reference guideline can then be used for Straight-Line or Curved AB Guidance.
Switching From Headland To Straight-Line Guidance
Once the operator has completed the desired number of headland circuits, the system can be
switched to apply the remainder of the field in either Straight-Line or Curved AB Guidance modes. If
the operator is being guided along a curved path when the pattern is switched, the lightbar will no
longer guide the operator along the curve.
If a reference guideline was established during Headland Guidance, CenterLine will automatically
guide the vehicle along the closest parallel line as soon as the operator switch es to Straight-Line
Guidance. If a reference guideline was not established during Headland Guidance, the operator
must mark Points A and B at this time. The light will display <MARK A>, indicating that no reference
guideline exists.

Headland Guidance Lightbar Graphics
CenterLine’s Headland Guidance uses a lightbar text display graphic that aids the operator when
navigating parallel to a curved swath. The X-Track LED functionality that is used during Straight-Line
and Curved AB mode is also used during Headland Guidance.
A projected swath path graphic is displayed in the text display area of the lightbar. The projected
path is comprised of four horizontal bars. The bottom bar indicates the nearest proximity to the vehicle; the top bar indicates the furthest away. The width of the bars decrease as the distance from the
vehicle increases to add perspective to the view. The projected distance of the first bar from the front
of the vehicle is based on vehicle speed. A straight l ightbar display indi cates that there are no turns
approaching. A skewed lightbar display indicates that a turn is ap proaching in the direction the bars
are skewed. The X-Track LEDs indicate the vehicle’s position in relation to the guideline configured
during Swath mode. The X-Track LEDs do not provide information relating to the curved path ahead
of the vehicle; they simply indicate the vehicle’s location in regard to the established guideline.During the first Headland Guidance pass, the lightbar will display a “hollow” path, meaning that no guidance information is available. The first path must be completed before a parallel path can be
established (refer to Figure 3-10).

STRAIGHT-LINE GUIDANCE
Straight-Line Guidance provides vehicle guidance along straight lines based on a reference guideline. The initial step is to establish the reference guideline. The refe re nce guid elin e is u sed to calculate all other parallel guidelines. Refer to CHAPTER 3 - MARKING POINTS A AND B for additional
information.
To mark the initial Point A, drive along the first swath path. Typically, the guideline is marked along
the longest straight edge of a field boundary. While the vehicle is traveling along the initial swath, the
lightbar will display <MARK A>. As the vehicle travels over the desired Point A location, press the
Enter button to establish Point A.
The lightbar will immediate display <MARK B>. To establish Point B, press the Enter button once the
vehicle travels over the desired Point B location. The referen ce line i s now established. T he lig htbar
will begin displaying X-Track guidance information as we ll as user-selected messages that were
defined during Lightbar Setup (refer to CHAPTER 2 - LIGHTBAR for additional information).
Once the reference guideline has been established, the operator can begin Straight-Line Guidance.
The CenterLine software detects which guideline is the closest to the center line of th e vehicle and
provides guidance information with respect to that line. As the vehicle travels across the field, new
guidelines parallel to the reference guideline are established based on the swath width value
entered during guidance setup.

Curved AB Guidance
Curved AB Guidance works similarly to Straight-Line Guidance except it provides vehicle guidance
along curved lines based on a curved reference line. The first step is to establish a reference guideline. The reference guideline is used to calculate all othe r guidelines parallel to the path. Refer to
CHAPTER 3 - MARKING POINTS A AND B for additional information.
To mark the initial Point A, drive along the first swath path. It is recommended that the reference
guideline be established along the longest side of the field if possible. The curved guidelines
do not extend beyond Points A and B. The area beyond Points A and B are controlle d by
Straight-Line Guidance. While the vehicle is traveling alon g the initial swath, the lightbar will dis-
play <MARK A>. As the vehicle travels over the desired Point A location, press the Enter button to
establish Point A.
Figure 3-13: Curved A-B Guidance
The lightbar will immediately display <MARK B>. To establish Point B, press the Enter button once
the vehicle travels over the desired Point B location. The reference line is now established. The lightbar will begin displaying X-Track guidance information as well as user-selected messages that were
defined during Lightbar Setup (refer to CHAPTER 2 - LIGHTBAR for additional information).
Once the reference guideline has been established, the operator can begin Curved AB Guidance.
The CenterLine software detects which guideline is the closest to the center line of th e vehicle and
provides guidance information with respect to that line. As the vehicle travels across the field, new
guidelines parallel to the reference guideline are established based on the swath width value
entered during guidance setup. When navigating a turn at the end of the field, the lightbar will display
the distance to the next swath as illustrated in Figure 3-12.

an applied area, the lightbar will display <APPLIED>, even if application is turned off. When the vehicle exits the applied area, <APPLIED> will no longer be displayed on the lightbar.

Neighboring Swath Detection
Applied area detection also notifies the operator when the vehicle crossed into a previously applied
neighboring swath. Figure 3-15 illustrates an example on an applied area overlap. The vehicle can
overlap up to 25% of the swath width without notification. Once the edge of the ve hicle o verlaps the
neighboring swath by 25% or more, the lightbar will display <APPLIED>.

LIGHTBAR INDEX
The CenterLine lightbar is capable of displaying a considerable amount of information to the user.
The information can be represented as text on the lightbar, illuminated cross track LEDs, or a combination of text and lights. The information displayed on the lightbar depends on both user-defined settings and system warnings not controlled by the user.

Mapping Boundary. This message is displayed when the user is
mapping the field boundary. The arrow symbol indicates the
field boundary is on the left side of the vehicle.
Mapping Boundary. This message is displayed when the user is
mapping the field boundary. The arrow symbol indicates the
field boundary is on the right side of the vehicle.
System Warning. This message is displayed when there is a
loss of differential GPS correction. Guidance calculations are
stopped until differential corrections resume.
Lightbar Description
System Warning. This message is displayed when there is a
complete loss of GPS signal to the GPS receiver or Smartpad.
Guidance calculations are stopped until DGPS signal resumes.
Lightbar Version Message. This message is displayed when the
user starts CenterLine or runs the lightbar test. This number will
vary based on the lightbar version and model.
SWATH MANAGER 5
Swath Manager 5 should be configured as illustrated in the fo llowing dia grams. Make sure the controller and Swath Manager 5 switches are in the proper locations.
Create a boundary to lock the area of application. If a boundary is created a nd closed and the Auto
Boom switch is set to “engaged”, the system will not apply outside of the boundary. Refer to CHAPTER 3 - AREA DETERMINATION for additional information.

TILT COMPENSATION MODULE
CenterLine must be loaded with Software Version 1.10 or higher to be compatible with the Tilt Compensation Module. The Tilt Module must be leveled (refer to CHAPTER 2 - LEVEL for additional
information) and the antenna height must be set (refer to CHAPTER 2 - ANTENNA for additional
information). When operating the Tilt Compensation Module, the position data coming from the GPS
receiver will be compensated for vehicle tilt errors. Corrected information will be sent to the console.
When the vehicle experiences a sideways tilt, all guidance information is affected. For example, if
the GPS sensor is 12 feet / 3.65 meters above the ground, a 10 degree tilt gives a 2 foot / 0.61 meter
positioning error.

There are three LEDs visible on the Tilt Sensor that indicate the following:
• Blue - blinks two times per second when the unit is powered and running
• Green - steady ON when tilt correction is enabled; otherwise OFF
• Yellow - Blinks one time per second when valid GPS location data is being received
(NMEA-0183 GGA)

Tilt Compensation Module Installation
• Mount the Tilt Compensation module as close to the center of the vehicle side as possible.
• Mount the module on a plain parallel to the GPS antenna so that both the antenna and the
sensor tilt the same degree.
• Mount the module so the sensor is level and the connector is pointing upward.
• The module should be mounted rigidly to minimize vibration. Vibration will degrade the ability to sense tilt.
• It is recommended that nuts and bolts be used or self-tapping screws be used through the
two mounting holes on each end of the module.
• The arrow on the module decal must be pointing toward the front of the vehicle.
• DO NOT mount the module near extreme temperatures, upside down, or on its side.
