Panelview Plus to Slc-5/04 question

I have two PV+ 700 DH+ models which have to talk to one slc-5/04 over the DH+ network. They all have separate node addresses, Each pv700 has it's own device shortcut to the slc. The pv700's will communicate with the SLC separately but as soon as I put them both togather on the dh+ network one of them will not communicate with the SLC. I get a Timed out reading across one of the panelviews. Any ideas?

Is the speed the same on all nodes? (56kbps,...etc)?

Yes the speeds are all the same

Do you have the DH+ cables daisy chained to each other and are you using termination resistors each end.

Check the cabling on the blue hose. It is easy to mess up. Also, are there terminating resistors at both ends of the trunc line?

Also check your node addresses and make sure there isnt a duplicate!
