[RE-wrenches] GridBoss with Multiple FlexBoss Parallel Comms

[Brett Stigile]

Jasson

I just did a GridBoss job.  Two cat5 cables are needed between Inverters 
and GridBoss.  See diagrams on Gridboss manual page 36 and 37.

One very useful thing I found was the extra help when commissioning the 
system for the first time.  You can log into PowerStation go to Forms 
then schedule a conference call.  Through the conference call you can 
simply share your screen and they can walk you through the last few 
details.
