I am trying to communicate with 2 LX200V20 through a 1000m cable, it doesn't work.
It is working with a 300m cable.
the resistance for the 1000m cable is 204 Ohms and the 300m cable 60 Ohms.
I thought it was the resistance so i put a 200 Ohms on the 300m cable it was still working.
Any ideas why it is not working over the 1000m cable?
