I have read the relevant topics about SDI-12 integration and it would seem a SDI-12 to RS232 converter is needed.
I have been given an interfacing guide from the manufacturer for this device.
Below are snippets from this including commands. However i can only assume these will all chance once in RS232??
I'm trying to identify the next steps for development of this system using Arduino as i am new to the platform.
Thanks in advance
