Do your devices need to be run in a certain order or have the PAB cables in specific ports? I set up my P4 and powerbar. (PAB from P4 to powerbar). I previously had a stand alone doser and KH Director set up and have a PAB cable from the top port of the KH Director to the top port of the stand alone doser. To add it to the P4 can I just run a PAB cable from the powerbar to the bottom port of the KH Director? Then go assign the KH Director in the P4? When I look at assign in the KH Director the P4 and the powerbar show up there unchecked ??? Just curious if I need to clean it all up and in order. Thanks.
