1. Quick Start Guide
Important! Must be seeding in order to perform a complete calibration
For the following steps, if necessary, refer to the Calibration and
Operation section for more details.
Verify Total Number of Sensors
On the Main screen:
Turn on Loop 1 Power by selecting the red number to the
right of the Sensitivity icon.
Set the Sensitivity to 1 and press Update.
Tap the icon.
A popup window displays the message:
Loop1 x Sensors Detected! Expected 0 Sensors.
(x represents the number of installed sensors)
If the number of sensors is correct, select the Update Tower
1 soft key.
If the number of sensors is incorrect, see System
Troubleshooting.
Repeat for Loop 2 as needed.
Speed Set-Up
A Speed is needed in order to set up the Seed Rate Wizard.
If you are using Test Speed:

3. Introduction
About THE LEGEND SECTION AWARE Wi-Fi
THE LEGEND S.A. Wi-Fi
THE LEGEND S.A Wi-Fi is a Rate and Blockage ECU that
communicates with tablet computers using Wi-Fi technology. The
Wi-Fi system communicates with the smartphone/tablet via an
“App”(short for application). The App provides a user interface to
display the information about the air seeder operation. Using Wi-Fi
to communicate with the cab means quicker startups and no worries
about towing the seeder with the monitor harness.
The system operates with basic functionality that includes blockage
detection and seed rate indication in seeds per acre or pounds per
acre.
THE LEGEND S.A Wi-Fi uses infrared optical sensors that detect
the seed rate. Each sensor in turn sends its information to the
module, which relays it via a Wi-Fi radio link to the app on your
Android Wi-Fi phone/tablet. If there is a problem an alarm will be
indicated on the phone/tablet.
THE LEGEND S.A connects to the drill’s control system and once
a section is turned off no alarms will occur for that inactive section.
2 Loops / 120 Sensors each
THE LEGEND S.A Wi-Fi can communicate with two individually
controlled sensor loops each capable of handling 120 sensors.
(Separate seed and fertilizer runs).
THE LEGEND S.A Wi-Fi Features
2X faster notification of blockages
Not affected by wire breaks
10X higher seed rates
5X more resistant to chemical buildup
Improved snap-fit sensor cable connection
Built in GPS ground speed (needed for rate calculation)
Wi-Fi connection provides convenient easy to read interface
on android tablets
Ability to hook up to two tablets on one ECU
Section Aware and will not alarm when sections are off
Tip:
When compared to previous Agtron ART
systems

MND172201 P a g e | 9Software Revision 1.4.1
Using your Tablet with THE LEGEND
Any Android Wi-Fi-capable device should be able to communicate
with and control THE LEGEND S.A. Wi-Fi. When the device is
connected to the ECU via Wi-Fi using the App, it downloads the
information from the ECU and displays it on the device’s screen.
The Wi-Fi device can be used to operate and monitor your Seed Rate
and Blockage.
The Legend App must be the active App on the device in order to
indicate a blockage or change in seed rate (App must be open and
visible on the screen)

4. Installation
ECU Tractor Battery Harness
Select a mounting location for the battery harness so that the
DTP connector is at the tractor hitch
Connect the battery Harness to the DTP connector on the
ECU. (this connection should be at the tractor hitch to allow
for hitch disconnect)
Mount the ECU on the toolbar (main extension cables may
be needed) within 10ft of the tractor hitch
Connect red (+) power cable wire directly to the battery
positive terminal (30 amp fuse is required)
Connect the black (-) power cable wire directly to the
negative battery terminal
Do not connect the black cable to the tractor cab. Not
all tractor cabs are properly grounded.
When the ECU is not in use disconnect it from power. It may
drain the battery if not in use for long periods of time.
Antenna with Base Installation (Tow between Tank)
If using a Tow Between Tank, a magnetic base can be used to
place the antenna on top or front of a tank to achieve line of
site. (See the parts list associated with Figure 4-11)
Disconnect the antenna from the LEGEND S.A. Wi-Fi
ECU.
Connect the antenna to the magnetic base.
Connect the magnetic base cable to the ECU.
Mount the magnetic base and ECU in the desired location.
Colored Cable Tie Installation
Colored Cable Ties
The colored cable ties included in this kit are provided to assist in
easy installation and to differentiate between the two loops of
sensors
Use blue ties to attach Loop 1 cables.
Use yellow ties to attach Loop 2 cables.
Be sure to secure all cables, but DO NOT pinch cables too
tightly!
Tip:
Main Extension Cables may be needed to mount
the ECU in the desired location (Part#
9ARTM10, 9ARTM20).
Tip:
On 24 volt systems be sure to connect the
monitor to the correct battery. It must be
the one with its negative terminal connected
to the tractor chassis (ground). Connect the
red (+) lead of the monitor to the positive
(+) terminal of that battery and the black (-)
lead of the monitor to the battery.
Incorrect wiring could result in damage to
your monitor.
