I agree.

I Agree.
I thought it would be clearly apparent that the user could only connect my devices because the 9-pin serial gets converted to RJ-11 and would only be able to plug into my network. Each device on my network has two RJ-11 sockets that allows the units to be daisy chained on to the network (in parallel).

My existing devices are RS-485 now and they work, but I was just trying to come up with a simple to integrate RS-232 solution to save the end user some $$.
