 VPD and ET0 are calculated values.  

• Please confirm that each sensor has successfully been set to its new address by following the instructions from section 7.2. 
  
  

Stage 3: Installing the Data Logger, Solar Panel, and Antenna 

Now that the sensors are addressed and prepared, you can proceed with installing the core components of the system. 

Packing list 

• SDI-12 Data logger  

• Junction cable  

• Solar panel with bracket  

• Pole screw clamps  

• LTE wideband antenna  

• Screw pack  

• Tube clamp (included in the pack) 

Required tools 

• Drill and 3 mm drill bit for metal  

• 13mm deep socket or 13mm spanner
• Wire/cable stripper
• Cable cutters
• Silicon

• 7mm socket  

• 16 mm spanner 

• 3 mm and 6 mm Allen key 

• Screwdriver set - flat and phillips

  

 

Step 3.1: Install the Solar Panel 

1. Choose the Installation Location: 

• Install the solar panels facing north in a location that receives maximum sunlight throughout the day without shade or obstructions. 

  2.   Mount the Solar Panel: 
Hold the panel against the pole and mark the spots where you will pre-drill the holes to secure the bracket. Make sure the panel is securely fastened and will not be easily dislodged by wind or weather. 

 

Step 3.2: Install the Data Logger 

1. Position the Data Logger: 

 
Open the side lids of the box and insert one of the bolts. Secure one side of the bracket first and then work on the other side.  

Feed one of the bolts through and hold it in place with an Allen key. Add the bracket on the backside of the box and secure it loosely with a washer and a nylock nut.  

Then feed in the second bolt, hold it in place, and secure it with a washer and a nylock nut. Centre the bracket and hand-tighten the bolts with an allen key and a spanner.  

Make sure the bracket is centred before tightening the bolts into place. Do not over-tighten the screws, because it could damage the enclosure.  

Thread the tube clamp through the metal bar and secure the box to the pole 

 

Step 3.3: Install the Antenna 

1. Position the Antenna: 

• Install the antenna in an elevated position to maximize signal reception.  

  2.   Mount the Antenna: 

• Use the mounting hardware provided to fasten the antenna securely. Remove the plastic cover and install the mounting bracket to raise the antenna to a high position on the post with 2x self-drilling screws. Sometimes it is advisable to pre-drill the post to avoid slipping and injury during installation. Mark one screw hole on the post, pre-drill, and install the bracket with a self-drilling screw, then pre-drill the second hole and install the second screw.  

   

Feed the cable and connector through the bracket and remove the slotted nut from the antenna. Feed the cable through the slotted nut and secure the antenna to the bracket with the slotted nut. Do not over-tighten the nut, because it could damage the antenna.  

  3. Connect the Antenna:  

•  Connect the antenna cable to the data logger, ensuring a secure connection. Tighten the connectors but avoid over-tightening to prevent damage.
• If you have excess antenna cable, wind it up in a figure-eight motion and secure it to the post with a cable tie.  
  

Step 3.4: Connections 

Remove the front lid of the data logger to access the cables. Please be careful when removing the lid as the batteries may have become dislodged and may fall out of the box. If this has occurred, please reinstall batteries and make sure there is a small gap (approx. 2mm) between the batteries and the right side if the box internals. 

Power up the Data Logger: 

• Feed the solar panel cable through the cable gland and connect into the solar terminal block (bottom left side terminal) 
• Connect the cables making sure the black cable goes to the left and the red cable connects to the right.  
  
• Remove the yellow protective caps from the batteries and connect the cables. Black cable to the black negative pole of the battery and red cable to the red positive pole of the battery. Connect cables into the battery terminal block (bottom right side terminal) making sure the black cable goes to the left and the red cable connects to the right.  
  
  
• 
• You should see a red LED light on the central controller and another red LED light on the communication module 
  

If, for any reason, the red lights do not come on, please contact our support team at:

If everything looks as in the above photo, close the lid of the enclosure and tighten the screws hand-tight in a crosswise fashion. Start with the top left corner and tighten the screw until you feel some resistance. Do not overtighten the lid screws. Then move to the bottom right screw, followed by the top right screw, and finally the bottom left screw. Repeat the process until the lid is securely tightened.  

Once you have completed the installation, send our support team an email or give us a call and we will check that the unit is communicating properly.
