      Bind a DXM to a node and Run a Site Survey

      Pair the DXM gateway to a TL70 node. When completed, validate the connection by running a site survey.

      Summary

      The process on how to bind a TL70 to a DXM, test the connection between the two through a Site Survey, and interpret the results of the Site Survey.

      Process: Binding a Node

      1. Connect the DXM and the TL70 to power.
      2. Take the cap off the TL70 node.
      3. Use the arrows to select "ISM Radio" from the DXM's menu and press the [enter] button.
      4. Select "Binding" from the menu and press the enter button.
      5. Choose a node number for the TL70 you are pairing. The node numbers cannot be duplicated. If you used the node number before, the new binding would overwrite the previous one. 
      6. Use the arrows to increase or decrease the number on the screen. When you find the node number that would be associated with this TL70, press enter.
      7. Click the binding button on the TL70 associated with the node number three time. The clicks should be one after the other. 
      8. The light on the TL70 will flash green when it is paired. Please refer to the table below for a more detailed explanation on the LED behavior.

      Process: Site Survey

      If you are doing a site survey after you bind a node, please proceed to step number 2 after pressing the back button twice.

      1. Use the arrows to select "ISM Radio" from the DXM's menu and press the [enter] button.
      2. Select "Site Survey" from the menu and press the enter button.
      3. Choose the node number you want to do the Site Survey on using the arrows and press the enter button. 
      4. A test will start running. A good Site Survey is between 80 and 100 on green. An acceptable Site Survey is between 60 and 80 on green. Anything below 60 on green means there is a poor signal quality. 
      5. When you are done with the Site Survey, press the back button twice to return to the menu.

      Interpreting the Site Survey Results

      Result Description
      Green Packages received at a strong signal (greater than -90dBm)
      Yellow Packages received at a good signal (between -90dBm and -100dBm)
      Red Packages received at a weak signal (less than -100dBm)
      Missed Packages not received on the first transmission and requiring a re-entry. The transmitter re-sends the packet until all data is received. 

      Improving the Site Survey's Result

      If the site survey has a poor result, please contact Support with the results.

      • If the results have more yellow than green, consider replacing the node's or gateway's antenna. 
      • If the line-of-sight has obstructions like man-made objects and the Missed packages exceed 25:
        • Install the antenna at a higher position.
        • Higher gain antenna.
        • Decrease the distance between devices.
