Hi All
I'm trying to connect a power meter (see link)to an Arduino to use its power readings to control the operation of a wind turbine. What is the best way to interface the device?

Thanks for your help

There are shields for that:

If you google "Arduino rs485" you will find other solutions as well. Converting TTL Serial to RS485 requires not much more than a cheap IC and a couple of resistors, but a ready made shield is easier and probably a better solution.
