EZ-Guide® Plus
What’s in the EZ-Guide Plus Box? When you receive your EZ-Guide Plus system, check that you have
received all the components, as detailed on the packing list. The fol-
lowing diagram shows the standard components.
Note — The antenna, antenna cable, magnetic mount, and metal
plate are included only if you purchased the system with integrated
GPS.
Caution — Keep the lightbar dry. Do not spray the lightbar with any
type of liquid as this will cause it to fail.
Inspect all contents for visible damage, such as scratches or dents. If
any components appear damaged, notify the shipping carrier. Keep
the shipping and packaging material for the carrier’s inspection.
Installing the System 1. Assemble the bracket kit. The bracket is reversible to optimize it for tilt angle. For more information, refer to
the instruc- tions in the bracket kit.
2. Attach the suction cup to the bracket.
3. Attach the power cable to the lightbar.
4. Mount the lightbar in the required position on the window. See Mounting the lightbar.
5. Attach the antenna to the magnetic mount.
6. Connect the antenna cable to the antenna and route the cable to the cab.
7. Attach the magnetic mount to the cab roof, along the vehicle centerline. Do one of the following:
– If the cab roof is steel, attach the magnetic mount directly to the roof.
– If the cab roof is not steel, attach the metal plate to the cab roof. Then attach the magnetic mount to the metal plate.
8. Connect the antenna cable to the lightbar.
9. Plug the power cable into the vehicle cigarette lighter. See Using the vehicle cigarette lighter, page 3.

EZ-Guide® Plus
Mounting the lightbar Caution — The suction cup mount is a temporary mounting device. Before you use it,
read the manufacturer’s instructions provided with the mounting kit.
1. Dampen the rubber seal on the suction cup.
2. Place the suction cup on a clean section of window, and then pump the plunger until its red line is no longer visible.
In addition:
• To ensure that the lightbar stays securely attached, pump the suction cup each day, or whenever the red line appears
on the plunger.
• If the lightbar does not stay securely attached with the suction cup, you can glue the cup to the window. Or, attach the
lightbar bracket directly to the dash, ceiling, or window.
Using the vehicle cigarette lighter If the power cable is plugged into a cigarette lighter that is not wired through the vehicle ignition, the lightbar receives
power whenever the cable is plugged in. To avoid draining the vehicle battery, turn off or disconnect the lightbar from
the power source if the vehicle will be unused for an extended time.
Minimizing GPS signal interference To minimize any interference to the GPS signal, make sure that the GPS antenna is at least 1 m (3 ft) from any other
antenna (including a radio antenna), and at least 100 m (300 ft) from any power line, radar dish, or cell phone tower.
Connecting other devices • To use the remote control or an external GPS receiver or an exter- na
sensor (for example, yield monitor), attach it directly to the lightbar
data port connector.
• To use the remote control and an external receiver or sensor, con-
nect them using the optional external interface cable.
• To connect a spray switch or device to receive speed pulse out-
puts, use the optional external interface cable.
Note — You cannot connect an external GPSreceiver and external
sensor at the same time.
Note — Connect the device to receive speed pulse outputs to con-
nector "A", a spray switch to connector "C", and the ground wire(s) to
connector "B" using the connector kit and instructions provided
with the kit. Do not supply power to the switch inputs.

EZ-Guide® Plus
Setting the antenna offset By default, the antenna is assumed to be at the implement position.
If the antenna is not mounted at the implement position, to ensure
correct guidance, set an antenna offset using Lightbar / Antenna
Offset.
1. Antenna offset ahead of implement
2. Vehicle centreline
3. Implement
Caution — The antenna must be mounted on the vehicle centerli-
ne. Otherwise, offline guidance will not be correct.
Coverage Area Coverage area is calculated whenever the spray switch is connected and on. For information on connecting a spray
switch, see Connecting other devices.
By default, Coverage Area is configured for display on the Status screen. To display Coverage Area on a map view instead,
use Lightbar / Status Text.
To save the coverage area value, you must Pause before turning the system off. Otherwise the value will be lost when you
restart the system.
Status text Status text Definition Swath number Swath number of the closest swath.

EZ-Guide® Plus
Getting Guidance The EZ-Guide Plus lightbar guidance system provides the following pattern options:
Pattern Definition AB Line Straight guidance based on A and B points that define the initial line.
A+ Straight guidance based on an A point and the previous line heading.
Identical curve Curve guidance based on the initial curve.
Adaptive curve Curve guidance based on the last curve driven.
Headland Records headlands of any shape as you drive around the field. Can provide guidance on multiple
headland passes and straight swath guidance inside the headlands.
For more information, see Using Guidance Patterns, page 11.
Note — For best possible GPS accuracy, wait for 15 minutes after you turn on the EZ-Guide Plus lightbar each day. This
allows time for the WAAS almanac data to be downloaded. If you set an AB Line before the WAAS almanac is downloa- ded,
you can get significant position drifts within that first 15 minutes.
Resetting Guidance
1. Select 9. The Guidance Pattern screen appears.
2. Press u or D to choose the required pattern and then press o.
A message appears asking you to confirm your choice.
This prevents accidental resetting of the guidance pattern.
3. To confirm, press o.
Configuring the Swath Width Once you select a pattern, the Swath Width screen appears:
• To change the swath width, press u or D.
• To accept the swath width, press o.
Tip — Set the swath width to 0.3 m (1 ft) less than the total imple-
ment width, to avoid skips between swaths.
12
EZ-Guide® Plus
Using Guidance Patterns This section describes how to define and use each of the available swath patterns.
The AB Line is a line that runs between Point A and Point B, although you may not always set a Point B. In most cases, the
AB Line is the reference line for subsequent swaths.
The start and end of the initial swath that defines the swath pattern appear on the lightbar screen as a circle (Point A)
and a square (Point B).
Swaths drawn on screen extend 1 km (0.62 mi) beyond Point A and Point B, and the extensions appear as dotted lines. This
makes it easier to see where the next swath is, and to get online after the turn.
Note — The initial swath (AB Line) appears as a thin, solid line; the current swath appears as a bold line.
AB Line pattern Use the AB Line pattern when no headlands are required and you
drive the field in parallel straight lines.
1. At the start of the first swath, map Point A.
2. Drive to the other end of the field, and at the end of the first
swath, map Point B.
3. Turn left or right for the next swath. The next swath is
automatically selected.
4. Steer the vehicle so that you center the green lights in the
lightbar as you drive forward along the swath.
Tip — Set Point B part way down the swath to get guidance down
the first pass, and then reset Point B at the end of the field.
A+ pattern Use the A+ pattern when you need guidance exactly parallel to the last
AB Line, for example:
• adjacent fields
• map the AB Line on a road down the side of the field
• skip an access road in a field
1. To map the start of the first swath, map Point A.
The heading of the AB Line equals either the previous AB heading
or the manually entered heading (if the current vehicle heading is
wit- hin +/-90 degrees of the AB heading). Otherwise the A+
heading is in the opposite direction.
2. Follow the AB Line for guidance down the first swath.
3. Turn left or right for the next swath. The next swath is
automatically selected.
4. Steer the vehicle so that you center the green lights in the lightbar
as you drive forward along the swath.
13
EZ-Guide® Plus
Identical curve pattern Use the Identical curve pattern when you want to work the field
with gentle curves. This pattern provides guidance based on the ini-
tial curve. It ignores any deviation around an obstacle.
1. At the start of the first swath, map Point A.
2. Drive the initial curve. At the other end of the first swath, map
Point B.
3. Turn left or right for the next swath. The next swath is automatical-
ly selected.
4. Steer the vehicle so that you center the green lights in the
lightbar as you drive forward along the swath.
Adaptive curve pattern Use the Adaptive curve pattern to follow gentle contours in the
field, or when you need to avoid obstacles. This pattern provides
guidance based on the last curve driven.
Simple Curves To drive simple adaptive curves:
1. At the start of the first swath, map Point A.
2. Drive the initial curve.
3. Turn left or right for the next swath. The next swath is
automatically selected.
4. Steer the vehicle so that you center the green lights in the
lightbar as you drive forward along the swath.
Note — By default, the end of the swath is automatically detected when you do a U-turn. If you prefer to manually mark
the end of each swath, from the configuration menu, select Guidance / Auto-detect Turn and change to Off. You must
then reset Point B at the end of every pass, to mark the end of the swath before you start the turn.
C-clamp To use the adaptive curve pattern to get C-clamp guidance with the
default of Auto-detect Turn set to On, do the following:
1. At the start of the headland, map Point A.
2. Drive around the headland in a C-clamp pattern.
3. Turn left or right for the next swath. The next swath is automati-
cally selected.
4. Steer the vehicle so that the green lights in the lightbar are cente-
red as you drive forward along the swath.
Note — The bold lines on the graph show where you must drive without guidance.
14
EZ-Guide® Plus
Spiral To use the adaptive curve pattern to get spiral guidance into the
center of the field:
1. From the Guidance menu, select Autodetect Turn to Off.
2. Start a new field using the Adaptive Curve pattern.
3. At the start of the headland, map Point A.
4. Drive around the headland.
5. When you are nearly back at Point A, map Point B.
6. Turn into the field. The next swath is generated off the last pass.
7. On each pass, when you are nearly back to where you started the
headland, reset B to mark the end of the swath.
Note — Make sure that you are not within one swath width of the start point. If you are, Point B will not be set.
Headlands pattern Use the Headlands pattern when:
• you need to apply the headland area first, to give you room to turn when you apply the straight swaths
• you want to know the area of the field You can do as many headland circuits as required before you change to straight
swaths. The headlands pattern automatically increments to the next headland when you enter the circle around the
start point of the headland.
Single headland 1. Start the headland.
2. Drive around the field area. The headland is recorded.
3. Identify the current headland circuit as the final one.
The head- land is still recorded until you reach the circle around
the start point.
4. To map the start of the first straight swath, map Point A.
Note — Do this before you enter the circle around the start point or
map A and B points.
5. Drive to the other end of the field and map Point B.
6. Enter the circle around the start point of the headland to complete the headland. The area is then displayed.
7. Turn left or right for the next swath. The next swath is automatically selected. Steer the vehicle to center the green
lights in the lightbar as you drive forward along the swath.
Note — Straight swaths automatically fill the headland boundary. The AB Line does not need to be the full length of the field.
15
EZ-Guide® Plus
Multiple headlands 1. Start the headland.
2. Drive around the field area. The headland is recorded.
3. When you return to the headland start point, the next headland
swath is automatically generated.
4. Identify the current headland circuit as the final one. You must do
this before you enter the circle around the start point or map A an
B points.
You continue to receive guidance to the final headland until you
drive off the pass by half a swath.
5. To map the start of the first straight swath, map Point A at any
time.
6. Drive to the other end of the field then map Point B.
7. Turn left or right for the next swath. The next swath is automati-
cally selected.
8. Steer the vehicle to center the green lights in the lightbar as you
drive forward along the swath.
Note — Straight swaths automatically fill the headland boundary. The AB Line does not need to be the full length of the field.
Center-pivot pattern Use the Center-pivot pattern for a field that is irrigated using a cen-
ter-pivot. With this pattern, you can drive concentric circles around
the center-pivot.
Note — To work from the center of the field outwards, the initial
pivot must have:
• a radius of at least two swath widths
• an arc length of at least two swath widths
1. Position one wheel of the vehicle in a pivot wheel rut, with the
rear of the vehicle to the pivot arm (or to the edge of the field, if
the field is not a full circle pivot).
2. To start the pivot, map Point A.
3. Drive around the field. Keep the vehicle wheel in the rut. The
lightbar does not yet provide guidance.
4. When you are almost back to the pivot arm or the edge of the
field, map Point B.
EZ-Guide Plus generates guidance swaths.
5. Turn left or right for the next swath. The next swath is automati-
cally selected.
6. Steer your vehicle so that you center the green lights in the
lightbar as you drive forward along the swath.
Note — You must drive at least half a circle before you can set the
end of the pivot.
Once you define the pivot, you can drive swaths inside or outside
the first swath.
16
EZ-Guide® Plus
Nudge Use nudge to move the guidance line back to the correct path to:
• correct for GPS position drift when returning to the field for guidance, for example after pausing or turning the unit off a
on
• correct for GPS satellite constellation changes while driving in the field.
On the ground – Vehicle on line with current swath/row.
On screen – Vehicle offline. Nudge left to correct..
Nudge is always applied to the guidance line relative to the vehicle heading.
To nudge, select 1 or 3. Each nudge moves the guidance line 3 inches. For example, if you press 3 twice, the total nudge
distance is 6 inches to the right.
To display the total accumulated nudge perpendicular to the current vehicle heading, use Lightbar / Status Text.
Configure Nudge to appear on a map view or Status screen.
To reset the nudge distance to 0, select Guidance / Reset Nudge.
17
EZ-Guide® Plus
Pause and Resume To pause guidance, select 2 or press p on the remote control. When
you pause guidance:
• The display changes to the Plan View map (if the Display Config /
View option is set to Auto).
• An icon appears at the pause location and indicates the direction o
pause.
• The pause swath appears on the screen.
• The screen automatically zooms to keep your current position
and the pause icon on the screen. You cannot zoom manually.
• A dotted line joins your current position and the pause point.
• The map status text changes to display the distance to the pause
point and the offline distance from the pause swath.
• The LEDs do not provide offline guidance while you are more
than half a swath from the pause swath.
• Progress lines and adjacent swaths are not displayed.
To resume guidance, select 2 or press p on the remote control.
Speed Pulse Output The EZ-Guide Plus lightbar can output speed pulse. This can be used to:
• Replace the radar / true ground speed sensor for speed on the vehicle.
• Send speed to any other agricultural device requiring speed pulses, for example, yield monitor or variable rate control-
ler. For information on connecting a device to the speed pulse outputs, see Connecting other devices, page 3.
To enable pulse output, use Lightbar / Pulse Output to select the output rate expected by your device.
Configuring Guidance Settings You can configure the guidance and warning settings of the EZ-
Guide Plus lightbar guidance system to suit your personal preferen-
ce and your application.
18
EZ-Guide® Plus
Guidance Settings Configure the following lightbar settings from the Guidance menu.
LED mode There are two LED modes:
Mode Definition Chase: Chase the lights to stay online. The lights represent the swath location relative to the vehicle.
Pull: Center the lights to stay online. The lights represent the vehicle location relative to the swath.
LED spacing The LED spacing is the distance represented by one LED. Decrease the LED spacing to increase the sensitivity of the LEDs.
Look ahead Use the look ahead time to predict your future vehicle path to allow for reaction time
and vehicle turn speed. Set the look ahead time in seconds, as shown below:
Speed Look Ahead Time 0–13 kph (0–8 mph) 1 second
13–24 kph (8–15 mph) 2 seconds
24+ kph (15+ mph) 3 seconds
For larger vehicles that take longer to turn, increase the look ahead time.
Note — For 4WD articulated tractors, always set the look ahead time to 0 seconds.
Auto-detect turn
This setting is used only for the Adaptive Curve pattern. This setting defaults to On, which means that a new swath is
automatically generated when a U-turn is detected. To manually identify the end of each adaptive curve swath, change this
setting to Off.
Warning Options Configure the following warning option settings from the Warnings menu. Warnings are displayed as a flashing message
on the screen.
Headland warning The EZ-Guide Plus system displays a message when you pass the
end of the swath. You can also configure a lead time for the head-
land warning so that the EZ-Guide Plus system warns you as you
approach the end of the swath. By default, this is set to 0 sec. To turn
the headland warning off, or to configure the lead time, use the
Headland Warning configuration screen.
Offline warning The EZ-Guide Plus system can display a message when you have gone too far offline. By default, this is set to 0'0" (no
warning). To configure an offline warning, use the Offline Warning configuration screen
19
EZ-Guide® Plus
Low accuracy warning There are three states for a low accuracy warning:
State Definition High accuracy only Uses only high accuracy positions for guidance. When low accuracy positions are received,
guidance is suspended. The lightbar displays a warning.
Warn low accuracy When low accuracy positions are received, guidance continues normally.
The lightbar displays a warning.
No warning When low accuracy positions are received, guidance continues normally. There is no warning.
Audible warning If you have a remote control or an alarm connected to the EZ-Guide system, it can emit an audible warning. To enable th
audible warning, use the Audible Warning configuration screen.
20
EZ-Guide® Plus
Using GPS You can purchase the AgGPS EZ-Guide Plus lightbar with or without the integrated GPS option.
Integrated GPS If you have a lightbar with integrated GPS, the GPS receiver is powered on as soon as the lightbar is powered on. To recei-
ve GPS satellite signals, connect the antenna to the antenna cable connector on the back of the lightbar.
Corrections To improve GPS accuracy, the integrated GPS receiver uses correction messages from a Wide Area Augmentation System
( WAAS) satellite, European Geostationary Navigation Overlay System (EGNOS) satellite, or Multifunctional Transport
Satellitebased Augmentation System (MSAS) satellite. By default, Corrections is set to Auto, so the receiver will automati-
cally use WAAS, EGNOS, or MSAS corrections according to your location. To disable all corrections, use GPS / Corrections and
change this setting to Off.
To manually enable or disable individual WAAS, EGNOS, or MSAS satellites:
1. From the GPS menu, select Corrections.
2. Select Custom.
3. Highlight the Exit command and press D to display Edit WAAS, Edit EGNOS, or Edit MSAS. Press o.
4. In the configuration screen that appears, turn on or off any satellites. To return to the Corrections screen, press o.
Note — MSAS is still in an early development phase and will only work in Japan.
External correction input If you are using the integrated GPS receiver, you can use external
RTCM corrections instead of WAAS, EGNOS, or MSAS corrections. To
configure the integrated GPS receiver to use external RTCM correc-
tions, set the Input option in Lightbar / Data Port Settings to
Corrections. Confirm that the port settings match the receiver out-
put settings.
Filter To improve accuracy at slow speeds, select GPS /Filter and set Speed t
Slow.
To prevent overshoot in tight corners at high speeds,change the
Speed setting to Fast.
21
EZ-Guide® Plus
GPS output If you are using the integrated GPS receiver, the EZ-Guide Plus
system is configured to output the GPS positions to another device
(for example, a yield monitor). By default, the GPS data is sent at
4800, 8N1, and the default messages are NMEA GGA and VTG at 1
Hz. To change the output rate, change the setting in Lightbar / Data
Port Settings. To output different messages, highlight Exit, and then
press D to display the NMEA Output option. Press o. The NMEA
Messages screen appears. Turn on or turn off the messages as requi-
red.
Note — To send NMEA output at 5 Hz, it is recommended that you change the baud rate to 9600 or higher for best performance.
External GPS input You can use positions from an external GPS receiver. To do this,
change the input format at Lightbar / Data Port Settings to External
GPS. Confirm that the port settings match the receiver output. The
EZ-Guide Plus lightbar requires GGA positions for guidance. It is
recommended that you also configure your receiver to output VTG
messages.
Note — If the EZ-Guide Plus lightbar does not receive VTG messa-
ges, guidance may be erratic, especially if you have an antenna
offset or are working at slow speeds.
If you are using a receiver with RTK or OmniSTAR HP corrections, do not define a new guidance line until the Low
Accuracy message stops flashing. Otherwise, you may get significant pass-to-pass drift until the receiver reaches its hig-
hest level of accuracy (Fixed). If the GPS Status is Float, then the accuracy is still converging.
Note — When you use external GPS input, the EZ-Guide Plus system does not output GPS data to another device. To send GPS positions to another device, connect the external receiver directly to the device.
Receiver configuration The default settings of the integrated GPS receiver should be suitable for most applications and locations. If you need to
change any advanced receiver settings, use the AgRemote software. For AgRemote to communicate with the lightbar,
you must set the input format at Lightbar / Data Port Settings to Diagnostics. You cannot use the Auto port configuration
/ Force connection options in AgRemote. You must manually set theparity and baud options in the Data Port Settings
screen to match the AgRemote settings.

Non-Integrated GPS Option If you have a lightbar without integrated GPS, the lightbar defaults to receive external GPS positions. Simply connect the
GPS receiver to the lightbar and confirm that the receiver is configured to output NMEA GGA and VTG messages at 5 Hz,

Getting a Clear View of the Sky To receive signals from GPS satellites, you must have a clear view of the sky. GPS does not work indoors.
Anything that blocks light also blocks GPS satellite signals. This includes people, buildings, heavy tree cover, and vehicles.
GPS signals can pass through leaves, plastic, and glass, but these all significantly weaken the signal.
