Question on adding 2nd doser to my 1st doser controlled by P3 EX

[Neverwouldof]

I have a 4 plug non PAB powerbar set on S1-S4 and my 1st GHL 4 doser unit plugged into S5-S8. I want to add a 2nd GHL 3 doser unit and plug it in to the out of the 1st Doser unit. I have many PAB 6 outlet powerbars setup already all the way up to Socket 32. I'm guessing there is no way to get the 2nd Doser to start at 33 correct? I would have to go redo all of my sockets again to have the 2nd unit start after S8 and they would be recognized as S9-S11 ?

Any suggestions would help

Hello,
if you connect the second doser to the first at S5S8, then you have to set this port to digital operation.
When you do this, then the numbering from 25-48 is possible at this port.
You would have to renumber the first dosing unit to 33-36 and the second one to 37-39.
