GreenSeeker RT200 System Installation Guide 9
1 Introduction
System overview
The GreenSeeker RT200 variable rate application and mapping system is a tool for variably
applying agricultural chemicals based on real-time measurements of the crop. The sensors
measure NDVI (Normalized Difference Vegetation Index) of the plants while traversing the
field, and the software collects the data that can be used to generate maps of the NDVI and
rates (where applicable) for crop analysis and historical data collection. This type of data can
be used in conjunction with other agronomic references to index nutrient response, crop
condition, yield potential, stress, pest, and disease impact in a quantitative manner. The
RT200 system can be used to monitor changing crop conditions during the growing season
and the effects of different levels of an input compared to a defined standard.
The applicator allows you to variably apply agricultural chemicals in real time (as the
applicator passes over the crop). The NDVI-based variable rate algorithm and parameters
may be selected in the field, and all rate changes are then made "on the go," so there are no
lengthy delays between evaluating the crop and application. When applying fertilizer or other
material, the NDVI, the target rate on, and the applied rate are mapped simultaneously with
the GreenSeeker RT200 system. Some spray controllers do not respond with an 'As Applied'
value.
The GreenSeeker optical sensor emits light at two specific wavelengths, and measures the
reflected light. The microprocessor in the sensor analyzes the reflected light and calculates
the resulting Index value. The data from each sensor is collected by the RT200 interface
module, processed and then transmitted to a PDA in the cab running one of the following:
• Farm Works Mobile software
• Version 3.0 or later of the FmX
®
integrated display
The Farm Works Mobile software displays the NDVI and location in real-time, logs the output
data to a file, and sends the appropriate rates to the applicator's rate controller or FmX
integrated display. The logged data is easily transferred to a desktop computer for analysis.
Note – This document does not describe how to use the software: Please refer to the appropriate
software documentation.
The ruggedized PDA (Personal Digital Assistant) could be a Trimble Recon
®
or Nomad®
handheld computer. In this document, “PDA” refers to either handheld model: If anything
refers to only one model, this is clearly indicated.
10 GreenSeeker RT200 System Installation Guide
Definitions of terms
The following terms occur throughout this manual and in the Farm Works Mobile software.
Becoming familiar with the terms will make using the software much easier.
CAN Controller Area Network.
A high-integrity data communications bus for real-time applications that operates at data
rates of up to 1 Megabit per second, and has excellent error detection and confinement
capabilities
GDD Growing Degree Days.
Some GreenSeeker algorithms use this value as an input to determine expected plant
growth stage. For more informaiton, see "Where to Find GDD Information" at
http://www.greenseeker.com/software/.
GPS Global Positioning System.
A system using satellites, receivers and software to allow users to determine their exact
geographic position.
N Nitrogen fertilizer
NDVI Normalized Difference Vegetation Index.
Commonly used to measure plant health and vigor.
NDVI = (NIR_reflected Red_reflected)/(NIR_reflected + Red_reflected).
NUE Nitrogen Use Efficiency.
A percentage of nitrogen taken up by the plant. For example, an NUE of 60% means that 6
lbs. of nitrogen fertilizer is expected to be used by the plant that year for every 10 lbs.
applied. For more information, see www.nue.okstate.edu.
NRS Nitrogen Rich Strip.
This reference strip/area determines the amount of nitrogen being made available to the
plant by the environment (mineralization, and so on), and importantly the present year's
expected maximum yield potential and response to additional nitrogen.
PDA Personal Digital Assistant. See User Interface.
RI Response Index.
Provides an indication of how the crop will respond this season to additional N.
User Interface A portable hand held computer.
Typically, a ruggedized PDA such as a Trimble Recon or Trimble Nomad handheld computer.
VI Vegetation Index.
A value that is calculated (or derived) from sets of remotely-sensed data that is used to
quantify plant health, stress, and vigor.
VRA Variable Rate Application.
Based on information supplied to a rate controller, the rate of fertilizer or other chemical
applied.

Care and maintenance
C
WARNING – There are no field serviceable components of the electronic system; do not attempt
any field repair of a malfunctioning controller or sensors. If you experience operating problems,
contact your local reseller, representative, or GreenSeeker distributor for assistance.
You must take good care of your GreenSeeker RT200 variable rate application and mapping
system to maintain high performance. At the end of each day of spraying, do the following:
• Check the detector and light source windows for dust and dirt, and wipe clean with a
soft rag.
• Do not leave the GreenSeeker systemoutdoors during extreme weather conditions. Wide
temperature variations may reduce the operating life of the system.
• Do not store a GreenSeeker system with the sensors facing upward. Doing so may allow
water to collect around the windows and gaskets, causing seal failures in those areas.
Direct sunlight can in some cases also focus enough energy into the sensor to damage
the detector.
• When rinsing off the machine, take care not to use high pressure to directly spray the
sensors. Even though all connectors and modules are fully sealed, there still exists
potential leakage from a pressurized stream.
• Every time the spray tank is filled, take a soft cloth and wipe the lenses of the sensors if
needed. Try to check sensors at least once a day during full-time operation.
• Be more aware of cleaning the sensors directly behind the machine.
• If you do not have ground protection devices on the boom, such as gauge wheels or
skids, take extra care to not run the boom into the ground. Also, be aware of sensor
vulnerability to stationary structures in the field. Sensors are usually mounted on the
front of the boom and do not have rigid protection.
• Rinse the boom after the end of every day. This will keep the system clean and wash any
corrosive materials off. This will greatly extend the life of your machine.
• At the beginning of each season, and periodically as required, check the hose clamps,
plumbing connections, and other fluid handling system components for tightness and
leak free operation.
• Make sure all wiring harness components remain fastened to the boom as to not
obstruct the view of the sensors and are free of any pinch points from boom folding and
movement.

2 Installation and Setup
Cables
Before mounting sensors, loosely route cables on the machine:
• Route all cables in areas where protection from mechanical movement can be assured.
• Do not kink any of the cables. You must allow at least a 6-inch (15-cm) bend radius in all
cables.
• Once cables are routed and all hardware is mounted, final placement of cables can be
made.
• Finalize by securing cables with tie wraps, zip ties, and so on as required.
Cable placement is as follows:

For emergency repair and troubleshooting purposes, see Appendix A, Cable Diagrams. These
diagrams are provided for use by qualified technicians only.
RT200 interface module
The RT200 interface module contains
circuitry to interface boom-mounted
sensors with the user interface. The
interface module has serial, CAN, and
power connections. It is an
environmentally sealed enclosure that
can be installed inside or outside the
cab.
Mount the module in close proximity
to the center of the boom-mounted
sensors (check the length of cables
400-1-277-EM and 400-1-278-EM for
suitable placement).
C
WARNING – Do not remove/cut or bypass the auto
adapter end of the power adapter cable for the PDA.
Do not connect directly to 12 V DC as this will cause
immediate failure of the PDA.
There are two small indicator lights on the lid.
The interface module has mounting brackets with drilled holes for mounting.
1. Mount the module in a structurally safe location on the machine. Trimble recommends
that you mount the module with connectors facing down to avoid water in the
connectors. An additional bracket may need to be made.
2. After the enclosure is mounted, connect cable 400-1-276-EM to the 12 V DC port. You
must fully rotate (approx ¼ turn) the gray retaining nut on the connector into the locked
position.
3. Connect cable 400-1-277-EM (this goes to the innermost sensor on the right boom) to
the port labeled Right CAN Bus.

4. Connect the second cable 400-1-277-EM (this goes to the innermost sensor on the left
boom) to the port labeled Left CAN Bus.
5. If using a PDA, connect cable 400-1-278-EM to the connection port labeled Serial Port.
Note – Be careful not to loosen the black strain relief portion of the connector when connecting or
disconnecting.
Note – If you are using the FmX display, the serial port is not used. Install the cable port cap to
protect this port:
User interface
Ruggedized PDA
The RT200 system includes a ruggedized PDA that is powered by a Windows Mobile®
operating system and that is pre-loaded with the Farm Works Mobile software. The Nomad
handheld uses a USB-to-4 port serial converter.
A removable memory card is supplied for the Nomad PDA for
easy data transfer; alternatively, connect the PDA to a desktop
computer for data transfer.
An adjustable mount is provided that allows you to easily
mount and remove the PDA in the cab. Place it where the
operator can easily view it and select the buttons:
1. Assemble the entire mounting structure before mounting
the base. Verify that the mounting location allows for
cable connections to the PDA.
2. Mount the base securely in the cab and then place the
PDA in its clip mount. Snap the PDA into place until
secure:
Note – See also the corresponding System Layout diagram, System layout with Trimble Nomad
handheld, page 16.

3. To keep the PDA’s battery charged, plug the auto-adapter power cable (included) into an
available 12 V DC outlet in the cab.
C
WARNING – Do not remove/cut or bypass the auto adapter end of the power adapter cable for
the PDA. Do not connect directly to 12 V DC as this will cause immediate failure of the PDA.
Note – The auto adapter for the Recon and Nomad handhelds are not interchangeable.
4. Once all the cables are connected, secure the cables in the cab to avoid damage to the
cable.
USB to serial box
This box is used for all systems that use the Trimble
Nomad handheld. It converts the USB port at the
bottom of the handheld into four DB9 serial ports.
FmX integrated display
Version 3.0 or later of the FmX integrated
display has a large color touchscreen and
integrated GPS and GLONASS receivers for
complete guidance, steering, mapping, and
application control.
The GreenSeeker plugin shows and stores the
data from the sensors, and communicates with
the applicator's rate controller. The GreenSeeker
plugin and VRA unlock code are required to
unlock the GreenSeeker function on the display.
The FmX integrated display is not packaged with the GreenSeeker RT200 system. For more
information, see the FmX Integrated Display Installation Instructions and the FmX Integrated
Display User Guide.
GreenSeeker sensors
C
CAUTION – GreenSeeker sensors are designed to operate in harsh environments. The sensor
enclosure and connections are environmentally sealed. Although the sensor is sealed, DO NOT
wash the sensor directly with a high pressure washer. To clean the sensors, use low pressure and
gentle washing procedures.
The sensor takes reflectance readings. The units generate their own illumination for use in
any lighting condition, day or night. When the unit is on, a red band of light shows directly
below the rectangular sensor window.
GreenSeeker RT200 System Installation Guide 21
2 Installation and Setup
The sensor operates by emitting light from the rectangular window onto a crop's canopy.
Reflected light from the canopy is focused on a detector behind the circular window:
• Both the rectangular and circular windows need to be free of any viewing obstructions
when mounted.
• Make sure that there are no obstructions, such as boom elements, cabling, hoses, below
any sensor - for 12" in front and 6" behind.
• Position sensors at least 48" apart. If they must be closer, offset them by at least 6".
• Sensors may be oriented forward or backward, that is, with the round end toward or
opposite the direction of travel. If they must be mounted close to each other, adjacent
sensors may be oriented alternating forward and backward to achieve offsets.
The sensor is designed for an optimal height of 28'' to 48'' (0.7 m to 1.2 m) from the
rectangular LED window to the crop canopy. The extended range (with greater deviation) is
26'' to 62'' (0.6 m to 1.6 m). The field of view (the width of the sensor measurement) is ~24''
(0.6 m) within the sensor's optimal height range.
Sensor readings are nearly constant with the optimal height range, but will vary somewhat
over the extended range. Momentary movement out of the operating height range does not
significantly affect performance of the RT200 system, but take care to keep sensors within the
recommended height range most of the time.
Mounting the sensors
• Typically, sensors are mounted using the standard
stainless steel bracket (provided). These brackets are
designed to fit most boom structures.
• The two outer sensors will have only one cable
connected. The other port in the outer sensors must be electrically terminated using a
small plug device called a CAN terminator. (The CAN terminator is usually pre-installed
in two sensors.) Mount these sensors in the outside (end) positions.
• The bracket can be secured to most boom structures with standard size U-bolts. One set
of U-bolts is included with the system. Some booms may require different U-bolts
and/or custom fabricated brackets.
22 GreenSeeker RT200 System Installation Guide
Installation and Setup 2
• The sensor is bolted to the bracket with two 5/16" bolts (provided).
• Sensors can be mounted in front of or behind a boom. The "direction" of the sensor is not
important, but the rectangular LED window must be parallel to the applicator boom:
• For crops such as wheat and canola, the RT200 system works best when sensors are
evenly spaced across the swath of the boom. For example, if a boom is 60 feet wide then
the sensors would be spaced approximately 10 feet apart and the outer two sensors
would be spaced approximately 5 feet from the tips. Boom folding procedures may
prevent even spacing of sensors. This is acceptable as long as the sensors are spread
across the boom as evenly as possible. For row crop applications, sensors must be
positioned directly over a row. When used in fields with a "guess row" or "wide and
narrow row" you may have to mount the sensor within your planter width.
GreenSeeker RT200 System Installation Guide 23
2 Installation and Setup
• Once the sensors are mounted, connect the sensor cables (400-1-265-240-EM ) as shown
in the system layout figure:
a. These cables have a 12-pin connector on each end. Slide the connector into
one of the ports on the sensor with the keyed side towards the front of the sensor.
b. After firmly seating the connector, use a Phillips screwdriver to secure the
connectors retaining ring. It does not matter which port the 400-1-265-240-EM
cables are connected to. The two outer sensors will have only one cable connected.
The other port in the outer sensors must be terminated.
c. Insert the terminator (if not already installed) in the unused port of the
outer sensors and then secure the retaining ring.
• As described in previous sections, use the 400-1-277-EM cables to connect the two inner
sensors to the interface module in the same way used for the 400-1-265-240-EM cables.
Once all cables are connected, secure the cables to the boom. Verify that cables will not
be damaged by moving parts.
Product rate controller
Most applicators come with an installed product rate controller. The RT200 system interfaces
with most available controllers. If you have a rate controller that is not currently supported by
the Farm Works Mobile software, contact Farm Works or your dealer to inquire about
obtaining support.
GPS receiver
A GPS receiver is necessary for logging geo-referenced data and viewing on-the-go mapping.
An applicator may already use a GPS receiver for other operations such as guidance. In many
cases it can be shared. The RT200 system accepts a serial connection (RS-232) from a GPS
receiver to the ruggedized PDA through a serial-to-USB converter.
Field preparations for nitrogen application
Field information
Before the GreenSeeker applicator can be used to apply nitrogen (N) across a field, you must
establish a nitrogen rich reference strip (NRS) before or shortly after planting. This reference
strip determines the amount of nitrogen being made available to the plant by the
environment mineralization and importantly, the present year's expected maximum yield
potential and response to additional nitrogen. The ideal NRS runs the length of the field, but
it should at least be 300 feet (91 m) long. Establish the NRS in a representative portion of the
field (that is, not in a high or low spot). The rate of N necessary to establish an NRS depends
on the crop and region, and should be equivalent to the highest rate necessary to satisfy crop
needs throughout the growing season. For example, winter wheat grown in the Southern
24 GreenSeeker RT200 System Installation Guide
Installation and Setup 2
Great Plains should have a minimum of 100 lbs N/acre applied to establish the NRS. Lower
pre-plant N rates should be applied across the rest of the field. Application of 20 lbs to 30 lbs
of pre-plant N/acre would be ideal for this situation.
The rest of the field is referred to as the Non-Reference (Non-Ref) portion. It may also be
referred to as the N-limited area or farmer practice region.
For best results, use the RT200 interface module to "read" the NRS and apply N at growth
stages dependent upon the crop algorithm used. For Trimble-supplied algorithms the
following is typically:
• Wheat: Feekes growth stage 4-6
• Corn: V8-V12.
For the sensors to accurately determine NDVI for topdressing (or sidedressing), plant
coverage should be at least 50%. The RT200 system with Farm Works Mobile software can use
the sensor mounted booms to read the NRS, or the GreenSeeker handheld sensor can be used
to determine field conditions.
To collect sensor readings for the NRS, pass the boom-mounted sensor (or handheld sensor)
over the crop at 32'' to 48" (81 cm to 122 cm) above the canopy. Sense a large area of the NRS
and non-reference portion of the field to accurately determine their respective NDVI values.
Once you have measured the NDVI values, enter them into the Farm Works Mobile software.
You can do this automatically with the boom-mounted sensors, or manually with the
GreenSeeker handheld sensor.
If response is obviously variable across the field, select an area where the difference between
the Reference and the Non-Reference areas are most apparent. This ensures that the
algorithm determines a rate that uses the highest yield potential prediction and maximum
response to N for that year.
To estimate yield potential, an environmental factor (Growing Degree Days) is used, which
takes into account weather and time since planting.
Note – Different GDD variations are used for different crops. To obtain the GDD value, you need
the planting date and sensing date. Regional values for GDD are available on the Internet. For
more information, see Where to Find GDD Information at http://www.greenseeker.com/software/.
Setting up the field
1. Decrease the pre-plant Nitrogen (N) application rate of the field to a level at least half of
previous total N applied during non-GreenSeeker management practice:
– For spring or winter wheat, if the application rate has historically been 100 lbs
N/acre, decrease the rate to 50 lbs N/acre.
– For corn, if application rates have historically been 200 lbs N/acre, decrease the rate
to 75 to 125 lbs N/acre.
GreenSeeker RT200 System Installation Guide 25
2 Installation and Setup
2. Prior to or shortly after planting, establish the NRS (Nitrogen Rich Strip) in a
representative portion of the field (that is, not in an historically high or low spot). Apply
an applicator’s width swath of N. The rate of N applied should be high enough to satisfy
crop N needs in a good year:
– For spring or winter wheat, the N rate should be at least 100 lbs N/acre.
– For corn, the N rate should be at least 200lbs N/acre.
Use a marker to ensure that you can easily find the NRS later in the season.
The ideal NRS runs the length of the field, but it should at least be 300 ft (91 m) long.
3. At the appropriate crop growth stage, take readings of the NRS and an adjacent part of
the field to be fertilized. For the supplied algorithms the following is typical:
– Wheat: Feekes growth stage 4-6.
– Corn: V8-V12.
4. Find the area where the nitrogen rich strip is most apparent in comparison to the rest of
the field (this indicates greatest potential for the crop).
5. Take sensor readings with the RT200 system or a handheld sensor to input to the
selected crop algorithm.
6. Match nozzles and/or rate control system to maximize response time and performance
for each field's requirements. For more information, refer to the application equipment
and rate control systems manuals.
26 GreenSeeker RT200 System Installation Guide
Installation and Setup 2
Field preparations for user-defined rates (custom table)
Example: Cotton Defoliant
Growers or crop consultants have historical crop knowledge that enables them to determine
different crop input requirements based upon biomass/size of the crop/plant, for example,
the variable rate application of defoliant in cotton. If this is the case, the field is scouted or
"field calibrated" to determine areas of the field that require different rates of defoliant. The
RT200 system or a GreenSeeker handheld sensor is used to obtain the NDVI values in
representative areas of the fiel, In the following figure, the NDVI of the crop was measured
under particular conditions for which the grower knew the approximate required rate, using
the GreenSeeker handheld sensor:
GreenSeeker RT200 System Installation Guide 27
2 Installation and Setup
Application information
Delivery system and liquid control
As with any variable rate system, the minimum and maximum rates obtainable depend on
the delivery system. The RT200 system can request any rate, but the actual rates delivered
depend on the rate controller and its components. Most liquid rate control systems control
(“throttle”) the pressure of the system to affect flow and application rate. There are also more
advanced delivery systems that use two booms, multiple nozzles, or special pulsing solenoids
on each nozzle, to obtain larger rate changes.
When using the RT200 system with a typical liquid delivery system, you must match nozzle
sizes to expected delivery rates. After the appropriate reference strip readings, GDD, and
selection of crop type are input into Farm Works Mobile software, the application graph can
be accessed to show the prescription rates at various sensor NDVI readings. Review the Crop
and Measurement screen features of the Farm Works Mobile software to determine the
expected delivery ranges in each specific field. To do this, tap Show Table. Depending on the
delivery system that is is used, there will be actual minimum and maximum rates obtainable.
These depend on components such as the pump, control valve, nozzles, and boom plumbing
sizes.
The Farm Works Mobile software has a feature that allows minimum and maximum rates to
be set, regardless of the crop algorithm prescription. Once you choose a nozzle set, set the
minimum at the lowest rate at which the nozzles will still give adequate
pattern/performance. Maximum rates may be limited by rates that lessen atomization or
drift.
Selecting a nozzle
It is usually best to match nozzles to the lower midrange of the typical rates shown on the
application graph. It is ultimately up to the grower or crop consultant to determine the
min/max rates and nozzles that are most appropriate.
Example
If most of your NDVI readings (in the area of the field not in the
NRS) are around 0.53, and the application graph shows at 0.53
NDVI you should apply 15 GPA, select a nozzle that can change
rates above and below this NDVI reading. You could select a
nozzle that puts out 12.5 GPA at its lowest pressure ( for
example, 20 psi) and 21 GPA at its highest pressure ( for
example, 60 psi). Since the penalty to under-fertilize (harm
yield) is usually greater than to over-fertilize (waste fertilizer), it
may be best to choose a strategy similar to the one shown here.
Modify the settings to fit your circumstances and to meet local
field and delivery system conditions.
