General Overview of the Crop Link Unit
Note: Once all sensors are connected and unit is ready to run, contact your AgSense Dealer to
finish setup, and configure this unit to read the sensors that you have installed.

Wiring the DC Power or Solar Panel to the
Crop Link Unit
Wiring the solar panel or 7-30v DC power Source: Find the last two terminals on the large
terminal strip labeled DC/SOL and GND
1. Connect the Black or Negative Wire (-) from the solar panel to the terminal marked GND
as shown above.
2. Connect the Red or Positive Wire (+) from the solar panel to the terminal marked
DC/SOL as shown above.

Wiring 120v AC Power to the Crop Link Unit
If you are not using DC power or Solar Power: how to wire 120v AC to the Crop Link.
1. Connect 120v AC to the terminal marked 120v –units pre-wired with a cable from
AgSense use a Black wire. Cable added by the customer should use the Black wire
here.
2. Connect the Neutral wire to the terminal marked N. –units pre-wired with cables
from AgSense use either a Brown/Black Stripe or a White wire. Cable added by the
customer should use the white wire.

Generic 4-20mA Sensor Wiring:
1. Wire colors likely will be different in your application, please compare your sensor colors
to the sensor functions listed below, and do not solely rely on the colors shown above!
2. 4-20mA Sensor must be 12v compatible.
3. Install the Sensor Power wire into the 12v Out terminal as shown with the red wire
example above.
4. Install the Sensor Ground and Sheild wires (if your sensor has them) into the GND
terminal as shown with the green wire example above
5. Install the Sensor 4-20mA Signal wire into input Analog5 4-20mA terminal (or Analog 6
4-20mA terminal) as shown with the black wire example above.
6. Make sure a jumper is installed as shown above (J16 if using Analog 5, or J18 if using
Analog 16) or the 4-20mA input will not work.
7. Remember to log into the user website, and select the 4-20mA Input from the dropdown
in the Config page for this unit, and fill in the values this sensor will have at 4mA and
20mA, enter the units this reflects, and then save the settings.

Scaled Voltage Input Wiring
1. Wire colors likely will be different in your application, please compare your sensor colors
to the sensor functions listed below, and do not solely rely on the colors shown above!
2. The sensor or voltage source connected must not exceed 6v DC Max!
3. Install the Signal / DC Voltage wire into the Analog input as shown with the red wire
example above (can use Analog 1, 2, 3 or 4).
4. Install the Ground wire from the Sensor / Voltage Source into the GND terminal as
shown with the black wire example above.
5. Remember to log into the user website, and select the Scaled Voltage Input from the
dropdown in the Config page for this unit, and fill in the min/max voltages this
Sensor/Voltage source will have, and what the scaled value and units this reflects, and
then save the settings.
