the field. This document covers the item listed below which will help you to use Sensors with
the SMS Mobile Software:
Basic Sensor Configuration
Connecting an Ag Leader OptRx Sensor
Connecting a Dualem 1s/2s/2/4 Sensor
Connecting a Geonics EM38/B/DD/MK2 Sensor
Connecting a GreenSeeker RT100/500/505 Sensor
Connecting a Holland Scientific 430 Sensor
Connecting a Minolta 502 SPAD Meter
Connecting a VERIS EC Surveyor and EC Instrument
Defining a Custom Sensor
Logging Data and Configuring Tooltips
Data can be logged from external sensors using SMS Mobile in all operations except for the
Boundary logging mode. Sensor configurations can be created, edited or deleted in SMS Mobile.
All sensors connected to SMS Mobile must have their own power source. Certain sensors,
such as the Veris equipment, also require their own GPS source.
There are several predefined configurations in SMS Mobile that are discussed later in this
document. The predefined settings can be modified when setting up your sensor, such as
modifying the COM Port your sensor will be using to communicate with SMS Mobile. Custom
sensors can also be setup with SMS Mobile to log data that is unique to your operation.
Connecting an Ag Leader OptRx Sensor to SMS Mobile [Back to Top]
1. Connect the OptRx Sensor (running firmware version 1.1 or
newer) to the 12 pin Deutsch cable and then connect the 9-pin

device (Ag Leader Part Number: 4002339-10).
2. Open the SMS Mobile Software and turn on the OptRx Sensor.
3. Tap the Setup menu and then the Sensors icon.
4. In the Available Sensor Configurations window tap Add.
5. Select Ag Leader OptRx from the Sensor Model drop down menu.
6. Choose the Operation you wish to record data from the OptRx in.
7. Enter a Configuration Name so that you can recognize this sensor in the future when
displayed in the list of Available Sensor Configurations.
10. Tap Test Sensor.
a. Tap OK after turning on the Dualem Sensor. (The arrow on the end of the
sensor MUST be pointing up and all wires connected. Newer sensors will say
“DUALEM” instead of displaying the arrow. The text must be in the upright and
readable position).
b. Once testing is complete you should receive a message indicating that
messages have been received and that it is connected.
c. Tap OK.
11. Select the Attributes you wish to log from the sensor by placing a check mark in the
