ok, Zw3100 is a low power module - and I guess for short distances.
What if I want to transmit in 1km max? Which module is better?
Is there a list of tr-rec modules that I can choose?
Another question I have is the following: This ZW is a direct in - direct out module? I mean I need no more circuitry to take en/decode the signal?
Now, my project: I have a number of local units connect to a main unit via RS485.
I Tr- Rec with all local in serial.
Can I replace the cables directly with ZW3100/2 ? Or do I need to modify the communication scheme?
