AB Protocols

Hey everyone,

I had a question regarding some of the protocols used in AB products. I did a search and did find some information, but was still a bit confused.

From what I saw:
DF1 is an RS232 protocol


DH+ is Data Highway plus (proprietary high speed blue hose)

DH485 is another {RS485 protocol}

Controlnet is a high speed coaxial communication protocol

My questions are:
What is the difference with DH and DH+?
Do they use the same cable? Is this the same cable as the RIO cable?


Thanks for your help!

DH-485 is 4-wire, while DH+ is 2-wire. DH+ and RIO are the same cable.
