    User manual is only images on Amazon
  

*by G***Y on Reviewed in the United States on November 12, 2018*

After writing to request a manual/specs from Ql Electronics, the only solution that seems to be provided is three very small images on Amazon. When zoomed in, they're barely legible, and not downloadable.  If you're already familiar with Modbus RTU communication and have a PLC or simulator already set up, this may be ok, but certainly not for a beginner.
