Gang..

Moving onto adding a Hawk's bay CC to my system. I have a rose inverter, a MNGP2 of course, and an upcoming Hawk's bay. Inside Rosie, I have the termination plug (for the can bus) installed, then a cat cable to the MMNGP2. Everything works fine.

Now, with the upcoming Hawk's bay, where does that fit into the can bus?

Should I move the termination plug to the Hawk's bay, and plug the Hawk's bay into the now opened socket (where the termination was at) in Rosie?

In my mind, Start with Hawk's bay. Termination plug inserted in it. Then cat cable to Rosie, cat cable to MNGP2.

Does that sound correct?
