  Hi all,
  
  My workplace is purchasing a new TriOS Opus nitrate sensor, and I’m wondering if I could get this working with the Mayfly.

  It communicates via MODBUS RS-485, so I figure my DIY modbus wing should be able to facilitate communication. However, I don’t really know where to begin after that.
  
  Can anyone provide any pointers or code that could get me started?
  
  Thanks for your help.
