Chapter 1 - Introduction
Simple, straight forward guidance and mapping.
Software Version 4.03
Midwest Technologies Inc.
Vehicle Guidance and Mapping Software
SmartPad II
Software Version 4.03
Welcome to SmartPad II
SmartPad II is a GPS driven swath guidance and mapping system. The SmartPad II system comes complete
with Lightbar, Interface cable and SmartPad II.
Guidance
The SmartPad II Guidance software allows an operator to perform product application while receiving guidance information from the Lightbar. The operator can select between four different guidance modes, Parallel, Curved, Curved A-B, and Center Pivot. Using SmartPad II you can map field boundaries while applying
products around the headlands, perform guidance in most any weather and visibility conditions. SmartPad II
utilizes the Lightbar as a visual aide, minimizing operator fatigue by reducing the need to constantly watch a
display. The Lightbar can display cross track error, swath number as well as several other useful text messages such as a warning when the vehicle enters a previously applied area. The SmartPad II system allows
you to create and view an as applied map of your field and vehicle swath trajectory while applying product
to the field. Application Reports can be generated in Fieldware Map Manager software.
Using SmartPad II is simple and intuitive. The Parallel and Curved A-B mode allows the operator to drive
the initial guide line, marking the start (A) point and the end (B) point. Once the initial line (A-B) has been
established, the operator can drive parallel or curved lines with respect to this line. The operator can at any
time during guidance create additional initial A-B guidelines in any orientation. This allows the operator to
employ parallel and curved swathing in as many suitable directions as required within a single field. In the
Curved mode; the operator can make several passes around the field headlands and receive curved guidance
information via the Lightbar, once the multiple headland passes are completed the operator has the option to
switch to Parallel, Curved A-B, or Circle Pivot mode or remain in curved guidance mode. The Circle Pivot
mode allows the user to drive an initial circle pass, marking the start (A) point and the end (B) point. This
establishes the initial circle guideline, the operator can now drive parallel circle lines with respect to the initial circle guideline. The SmartPad II software will automatically sense when the vehicle is departing one
line and approaching a new line and begin guiding the operator to, and along, the new line. This eliminates
the need to manually notify the software that you want to move to a new guideline.
Nav2Point
The SmartPad II Waypoint Navigation (Nav2Pt) software allows the operator to navigate to specific locations in and around a field. The Nav2Pt program allows you to navigate to specific pre-determined point
locations or to more generalized areas of a field based on various types of background data such as soil sample point maps. Once at a desired location you can add that location as a sample point and assign a point
number and name. The primary use of the Nav2Pt program will be for soil sampling. Sample points and
grids created in the Fieldware - Tools Form a Sampling Pattern program can be imported into this program.
When used in conjunction with the Lightbar, Nav2PT application can guide the operator to desired point
locations using the lightbar as a visual aide.
Mapper
The SmartPad II Mapper application allows the operator to map field boundaries, weed patches, insect infestation, ponds, tile lines, as well as any other feature important to field application. These features can be
mapped as points, lines, or polygons. The data collected in Mapper is stored in a file that can be used as a
background map when using the Guidance or Nav2Point application.
1-2 Chapter 1 - Introduction
Welcome to SmartPad II
SmartPad II
Software Version 4.03
Data collected using SmartPad II software can be viewed, edited or converted into other files formats using
the Fieldware - MapManager software, or imported directly into several standard Agricultural GIS packages
on the market today. This User’s Guide describes how to install, configure and use the SmartPad II product.
For technical information regarding other MID-TECH products such as the MID-TECH line of GPS receivers and rate controllers, please refer to the appropriate MID-TECH user’s guide.
We recommended that you read this user’s guide prior to using the SmartPad II product. This user’s guide
contains the following:
• Chapter 1, Introduction to SmartPad II, contains a product overview and instructions for installing the
SmartPad II hardware.
• Chapter 2, Getting Started, gives instructions on how to setup and configure the SmartPad II and software.
• Chapter 3, Real-Time Operation, describes SmartPad II real-time guidance and mapping.
• Chapter 4, Waypoint Navigation, describes SmartPad II real-time Nav2Point.
• Chapter 5, Mapper, describes SmartPad II real-time mapping options.
Using the optional CompactFlash data card, SmartPad II can also create and save to the card a vehicle application trajectory record file (.RCD). The CompactFlash data card is required to store any data, no data is
stored internally to the SmartPad II. You can also map points and hazards during the real-time guidance process. Any data saved to the CompactFlash card can be viewed and printed using MID-TECH FieldwareTools software included as an option with SmartPad II. If a field boundary is not available one can be created
based on the boom width while the operator is spraying or driving the perimeter of the field. Total field area,
in Acres or Hectares, is calculated, as well as total area applied. If a field boundary already exists, possibly
created using the MID-TECH Fieldware - Field Mapping application, it can be viewed in the background.

Installing Your System
It is important that you setup and install the SmartPad II hardware properly. Incorrect setup or poor installation may result in intermittent and erratic operation of both the SmartPad II hardware and software. This
User’s Guide does not cover GPS receiver setup and operation. You should review the appropriate operators
manual for installation instructions. We recommend connecting all hardware components prior to permanently installing each component in the vehicle. Once you have concluded that all components are interfaced
and running properly, you should disconnect everything and install them in the vehicle.It is very important
that you choose the installation location carefully, making sure that all cables and connections are easily
reached and there is no excess strain on any connections. A clean and proper installation will ensure hours
and hours of trouble free operation.
GPS Receiver
Please review your GPS receiver User’s Guide for specific installation instructions. Always check each cable
length prior to permanently installing the receiver. Make sure the serial cable from the GPS receiver to the
SmartPad II Interface cable is not crimped or damaged and is placed so that it will not get caught inadvertently by a foot or door.

Software Version 4.03
GPS Antenna
Care should be taken as to where you locate the D-GPS antenna. The most accurate D-GPS system in the
world is of no value if the antenna is located incorrectly. For any MID-TECH application employing guidance, the GPS antenna should be located along the long axis center line of the vehicle. If the vehicle long
axis center line and the center of the spray boom are not the same, i.e. the boom is not mounted to match the
center of the vehicle, then the antenna should be mounted in a location on the vehicle that matches the center
of the spray boom.
Figure 1-2: Mounting the GPS Antenna
Lightbar
The Lightbar should be located with in the operators field of view while under normal driving conditions.
The Lightbar can be mounted on the vehicle cab dash or ceiling. Interior installation is recommended. The
Lightbar is weather proof and can be mounted to the exterior of a vehicle. Exterior mounting may require
additional lengths of cable, measure this distance prior to permanent installation. Lightbar extension cables
are available through MID-TECH or your MID-TECH distributor. For in cab installation, minimize the head
movement required by the operator to view the Lightbar. When the Lightbar is installed in a location that
requires minimum or no effort to view, operator fatigue is greatly reduced. Use the two knobs on either end
of the Lightbar to adjust the tilt, see Figure 1-3.

SmartPad II and Interface Cable
The SmartPad II and Interface cable should be located in the cab so that the operator can easily reach, view
and operate the system. See Figure 1-4 and Figure 1-5 for instruction on how to connect the Lightbar and
SmartPad II to the interface cable. Make sure the interface cables are not under any excess strain, can not be
closed in a cab door or window, or stepped on by the operator. We recommended that the interface box be
mounted within arms reach of the operator and out of harms way.

Inserting the CompactFlash Card
The following instructions describe the basic procedure for inserting the optional 128MB CompactFlash
Data card into the SmartPad II:
• With power off, locate the CompactFlash card socket on the top of the SmartPad II, see Figure 1-6.
• Insert the CompactFlash card into the CompactFlash card socket. Make sure that the CompactFlash card
logo is facing out. Slide the card along the guide slots until it makes contact with the SmartPad II expansion socket.
• The card will slide freely until it reaches the pins on the SmartPad II’s expansion socket, at which point,
you will feel some resistance.
• At this point, you should feel the card settle onto the expansion socket pins. Only a slight amount of
force is required to seat the card into the socket.
• Once you are certain the card is properly aligned with the SmartPad II expansion socket, insert the card
slightly beyond the resistance point to ensure it is fully seated into the socket. DO NOT FORCE THE
CARD.

Storing Data on the CompactFlash Card
If you purchase the optional CompactFlash card with the SmartPad II product, you will be able to store As
Applied, boundary and point data to the card. The CompactFlash card must be inserted into the SmartPad II
card slot during the real-time guidance process. No data is stored internal to the SmartPad II.
In order for the SmartPad II software to recognize the CompactFlash card, the card must be inserted into the
SmartPad II prior to turning the unit on.
All data written to the CompactFlash card is stored at the root directory of the card. If you choose to view
existing data such as a previously mapped field boundary, the boundary file or any other compatible file type
(.RCD, GMF and.BND) must reside in the root directory of the CompactFlash card. If you create a folder or
directory on the CompactFlash card and store data it that folder, the SmartPad II software will not be able to
access that data.

Software Version 4.03
Fieldware/SmartPad II File Types
The SmartPad II software can store and view three different types of files, GMF, RCD and BND, all
described below in more detail. These file types are also compatible with the MID-TECH Fieldware software suite. That means data collected using the SmartPad II product can also be used in the Fieldware software suite. You can also use any RCD, BND or GMF file that was created using the Fieldware software suite
with the SmartPad II product. As an example, a field boundary (BND) created using Fieldware - Field Mapping software can be viewed in the SmartPad II software. All data collected using SmartPad II can be viewed
and printed using the Fieldware - Tools Map Manager program.
RCD
The RCD (Record) file type will contain a record of a product application created using SmartPad II, Fieldware-Parallel Swath Guidance and Fieldware-ARM. The contents of the RCD file will be the vehicle spray
trajectory and any controller feed back information that is supplied to the Fieldware software. SmartPad II
software does not record any controller feedback. No mapping attribute data will be stored in the record file.
Any attribute mapping done in applications that use the RCD file will be stored in a GMF file.
The last guideline used prior to exiting out of the SmartPad II software will be saved. If RCD data is not
stored to the CompactFlash card no guideline information will be saved.
MID-TECH software products that can create or view an RCD file are:
• SmartPad II,
• Fieldware-Parallel Swath Guidance,
•Fieldware-ARM,
• Fieldware-Tools Map Manager
GMF
The GMF (General Map File) file type encompasses all data collected that is not specific to any of the other
file type themes. Any general attribute/feature mapping such as weed boundaries will be stored in this file
type. All applications that allow attribute mapping will use a GMF file to store this data. As an example, the
SmartPad II software will allow the user to map a limited number of field attributes such as points and hazards, this data will not be written to the RCD file, instead this data will be written to a user selected GMF
file. By moving all additional attribute data out of the application specific file and into a GMF file we allow
the user to append additional data at a later date by using Fieldware - Field Mapping or Map Manager or any
other application that accepts a GMF file. Applications that will provide attribute mapping capabilities and
therefore use a GMF file are as follows:
• SmartPad II,
• Fieldware-Field Mapping,
• Fieldware-Parallel Swath Guidance,
•Fieldware-ARM,
• Fieldware-Sample and Waypoint Navigation,
• Fieldware-Tools Map Manager,
• Fieldware-Tools Form Grid.

The primary purpose of the BND file is to contain the boundary data for a particular field. Perimeter data
stored in a BND file can be viewed as a background map in several of the other Fieldware software applications. Boundary files can be created and appended to in SmartPad II, Fieldware-Mapper, Fieldware-Guide
and Fieldware-ARM applications. The BND file structure is identical to the GMF file structure, the BND
allows us to rapidly locate the boundary data for a particular field with in the client, farm filed directory
structure. SmartPad II does not utilized the Client Farm and Field directory structure. MID-TECH software
applications that utilize a BND file are:
• SmartPad II,
• Fieldware-Field Mapping,
• Fieldware-Parallel Swath Guidance,
•Fieldware-ARM,
• Fieldware-Sample and Waypoint Navigation,
• Fieldware-Tools Map Manager,
• Fieldware-Tools Form Grid.
GLN
The Guideline (GLN) file contains the guideline information created during the swathing or application process. This file can be automatically named to match the RCD file name, or can be custom named. The GLN
file can be used year after year in the same field, this eliminates the need to mark A and B points each time
you use the SmartPad II in the same field. MID-TECH software applications that utilize a GLN file are:
• SmartPad II,
• Fieldware-Parallel Swath Guidance,
•Fieldware-ARM,
• Fieldware-Tools Map Manager.

SmartPad II Software Overview
The SmartPad II software suite is made up of a Main Launcher and three software applications (programs), Guidance,
Nav2Point and Mapper. Each application can be broken down into two main components, Setup and Real-Time Mapping. Each of these components are described in more detail in following chapters. Figure 2-11 shows a flow diagram
of the SmartPad II software suite. All menu and menu items can be accessed and changed using the touchscreen or
the six keys located on the SmartPad II. For more description on how to use these six keys see “Operating SmartPad
II Software” on page 2-3.
The first time you run the SmartPad II software you may need to set a few system settings such as Date and Time
Zone, Units, SmartPad II settings and possibly Language, to configure the SmartPad II software suite the way you
prefer it. See “First Time Setup Process” on page 2-7 for more detail on setting up SmartPad II for the first time.
SmartPad II Main Launcher
Once the unit has powered up a SmartPad II splash screen will briefly appear, displaying the version number of the
software you have installed on the SmartPad II. The Main Launcher Menu page follows the splash screen, Figure 2-1.
The Main Launcher is where you can pick an application to run, either Guidance, Nav2Pt, or Mapper; System Settings and Tools are also located in the Main Launcher page. The Tools component of the Main Launcher contains several diagnostic tools that may help trouble-shoot problems with your GPS receiver and lightbar, see “SmartPad II
Tools” on page 2-24 for more details. For more information on the Main Launcher see “SmartPad II Main Launcher”
on page 2-8.

Dialog Boxes
The SmartPad II software uses dialog boxes for entering or selecting settings and values associated with each menu
item. There are two types of dialog boxes a Pick dialog box and an Alpha-Numeric dialog box. Notice that dialog
boxes also contain an Info Bar and a Key Code box.
Figure 2-3 shows an example of a Pick dialog box. A Pick dialog box allows the user to select from a list of existing
settings or values. Pick dialog settings are displayed using the keys, once the desired setting is displayed in
the dialog box, the setting is accepted or entered by pressing the key, this will also exit from the dialog and return
to the previous menu. The key allows the user to exit the dialog box without changing the setting.
Figure 2-4 shows an example of an Alpha-Numeric dialog box. This type of dialog box is used when the user is
required to enter a particular value such as a distance or a name. The complete value is made up of individual dialog
cells. In Figure 2-4, the final value is 22.0 feet and the current or highlighted cell is the 0. To enter 22.0 ft., the user
can use the on-screen keyboard by selecting the keyboard button or by selecting a 2 using the keys until a
2 was displayed. Next the user moves to the next cell, using the keys and selects another 2 using the same
method as the first 2. Finally the user moves to the decimal location and selects a 0. To accept the entire 22.0 ft. value
and return to the previous menu page, the user simply presses the key. The user can exit the dialog without chang-
ing the setting by pressing the key.

About the Guidance Application
Using the lightbar, the guidance function provides the operator with clear and intuitive steering assistance as well as
real-time application information. The operator can select between four different guidance modes, Parallel, Curved,
Curved A-B, and Center Pivot. Using SmartPad II you can map field boundaries while applying products around the
headlands, perform guidance in most any weather and visibility conditions. SmartPad II utilizes the Lightbar as a
visual aide, minimizing operator fatigue by reducing the need to constantly watch a display. The Lightbar can display
cross track error, swath number as well as several other useful text messages such as a warning when the vehicle
enters a previously applied area. The SmartPad II system allows you to create and view a where applied map of your
field and vehicle swath trajectory while applying product to the field. Application Reports can be generated in Fieldware Map Manager software.
Using SmartPad II is simple and intuitive. The Parallel and Curved A-B mode allows the operator to drive the initial
guide line, marking the start (A) point and the end (B) point. Once the initial line (A-B) has been established, the
operator can drive parallel or curved lines with respect to this line. The operator can at any time during guidance create additional initial A-B guidelines in any orientation. This allows the operator to employ parallel and curved swathing in as many suitable directions as required within a single field. In the Curved mode; the operator can make several
passes around the field headlands and receive curved guidance information via the Lightbar, once the multiple headland passes are completed the operator has the option to switch to Parallel mode or remain in curved guidance mode.
The Circle Pivot mode allows the user to drive an initial circle pass, marking the start (A) point and the end (B) point.
This establishes the initial circle guideline, the operator can now drive parallel circle lines with respect to the initial
circle guideline. The SmartPad II software will automatically sense when the vehicle is departing one line and
approaching a new line and begin guiding the operator to, and along, the new line. This eliminates the need to manually notify the software that you want to move to a new guideline.
Starting Guidance for the First Time
The first time you attempt to run the SmartPad II Guidance application you will need to enter the vehicle swath width.
To enter the swath width follow the steps outlined in “Swath Width” on page 3-5. You should also make sure that the
current date and time are set correctly, see Chapter 2 for more details.
Connect the SmartPad II to the SmartPad II Interface Cable, and apply 12 VDC power. It is not necessary to have the
Lightbar or GPS receiver connected and running to change the Vehicle Swath Width. Power the unit up by pressing
the On switch.

Swath Width
The guidance parameter Swath Width is the distance between guidelines. This width is typically determined by the
vehicle swath width or spread area, see Figure 3-3. Setting the swath width slightly smaller than the actual width will
reduce skips. Setting the swath width slightly larger than the actual swath width will reduce overlap.

Look Ahead
The Look Ahead value is the number of seconds ahead of the vehicle you would like the SmartPad II software to calculate the cross track error. Based on the vehicles speed and trajectory and this look ahead value, SmartPad II can
determine where the vehicle will be with respect to the current guideline. This setting will vary based on the vehicle
operators driving ability and preference. This value is only used with the guidance pattern Parallel. It is not used in
Headland curved guidance or the Circle Pivot pattern. A Look Ahead value that fits the operator best will result in
smoother guidance operations. Typically this value is set to 2 seconds.
To change the Look Ahead value; highlight the Look Ahead menu item and press . The Look Ahead dialog box

Drive Sensitivity
The Lightbar Menu item, Drive Sensitivity, allows you to set the distance you would like a single light on the SmartPad II Lightbar to represent. If a value of 1.5 feet is entered, then each light on the lightbar will be equal to 1.5 feet.
This allows you to quickly determine how far off the guideline you are. If the second light to the right of the “stacked”
center light is illuminated, then the vehicle is approximately three feet to the right of the guideline and you need to
turn the vehicle back to the left to get back on line. Figure 3-36 shows the lightbar (Display Mode = Swath) with a Xtrack error of 2.3 ft. When determining what value to enter into the menu field you must consider the accuracy of the
GPS/DGPS system you are using. Different DGPS sources provide different position accuracy. A good rule of thumb
is to set the drive sensitivity to a value slightly less than one half of the position accuracy of your DGPS receiver.
E.G., with a DGPS system that is accurate to with in 3 feet, set the Drive Sensitivity to a value between 1.2 and 1.5
feet.

About the Real-Time Guidance Process
Once you have the SmartPad II software correctly setup, the next step is to start up the real-time guidance process.
The real-time component of SmartPad II is where you are actually out in the field running guidance with the SmartPad II Lightbar and SmartPad II. At this stage you should have a DGPS receiver connected to the SmartPad II and
running properly. It is always a good idea to verify that your DGPS receiver is running properly and communicating
with the SmartPad II prior to driving out to the field. To verify that your receiver is working properly, connect it to the
GPS cable on the SmartPad II Interface and run the SmartPad II Receiver Status Tool, see Chapter 2. Once you are
sure your GPS receiver is running properly, you are ready to begin guidance.
Starting Real-Time Guidance
To start the real-time guidance process, highlight the Start Guidance menu item in the Main Menu page and press
, see Figure 3-50. In the example shown in Figure 3-50, the user setup the SmartPad II software not to collect any
data or map any points, hazards or field boundary. Because the user did not want to collect, map or view any data, the
SmartPad II software immediately moves to the Real-Time View page, once the key was pressed. This start up
sequence will vary depending on how you configure the Data Setup menu in the setup process. For more information
about the Data Setup menu see the Data Setup section in Chapter 2 of this User Guide.
Figure 3-50: Starting The Real-Time Guidance Process
The Real-Time View Page
There is only one view page associated with real-time guidance, see Figure 3-51. The left side of this view page contains the map window. This is where the vehicle and its trajectory can be viewed while running guidance. Other features such as the current guideline, hazards, points and the vehicle’s swath are displayed in the map window as well.
The right side of the view page contains several buttons located in the button bar, see Figure 3-51. A detailed description of each button is listed in Figure 3-52. The number of buttons located in the button bar will vary based on how
you have setup the SmartPad II software. For example, if you have selected to create the field boundary in the setup
process, a Map Field Boundary button will be included in the button bar. To navigate up and down in the button bar
use the keys located on the SmartPad II. To select or activate a highlighted button in the button bar press the
key on the SmartPad II.

The bottom of the view page contains the information window. Various information about the current real-time process will be displayed in this window. There is a specific Information button located in the button bar, when this button is either highlighted or pressed, information such as total area applied will be displayed. If you have a field
boundary displayed in the map window, the area of the field boundary, in Acres or Hectares, will also be displayed in
the information window.
Located at the bottom right corner of the view page is the key code box. This box displays which SmartPad II keys are
active based on the current view page and button bar state.

Zoom Pan Mode
In the Zoom Pan Mode the operator is allowed to zoom in and scroll across the screen. This is helpful to locate skips
or over lapped areas.
To activate the Zoom Pan Mode the operator must be zoomed to a point that the some of the view area is missing on
the screen. Locate the hand button down the right side of the real time screen Figure 3-55. When pressed the button
will then provide eight buttons (Up, Down, Left, and Right Arrows, Zoom in and out, Snap, and Exit) see “SmartPad

The Parallel Guidance Mode
This section describes how to run swath guidance when the Parallel pattern option is selected. The first step is to
establish the initial A-B guideline. This initial baseline is used to calculate all other guidelines parallel to it. It is
assumed that the SmartPad II setup described in Chapter 2 is complete and the Guidance Setup Pattern option
selected is Parallel.
Mark Point A
To mark the initial point A, begin driving along the first swath path, typically this would be along a straight edge of a
field boundary. Figure 3-60 shows the vehicle driving along the initial swath, the lightbar in this figure displays the
MARK A message. This message will appear until the guideline point A is established. To establish the guideline
point A, highlight the A button in the button bar and press , Figure 3-61.
