Trace SWI stacking cable question

littleharbor2littleharbor2 Solar Expert Posts: 1,735 ✭✭✭✭✭
I am trying to find out the difference between the SWI series and parallel stacking cables. At this point I have resigned to building my own being I cant find them anywhere. It looks like all the parts are readily available. The series cable seems to have 20 lines used in a 25 pin connector.  So does the parallel cable have, like one more or one less wire? Is it that simple?
Trying to add a diagram but it wont take.

Maybe somebody out there has a parallel stacking cable and can get a picture of it.

    Did you search the forum here? I threw out all of my info as it is just too old of electronics. I remember seeing stuff about it somewhere.

    Ya Dave. I've brought up the subject here before. Been through all those threads again. I need just specific info as to what separates the series cables from the parallel. I can build it now with that tidbit of info.

    The link looks to be still good... 

    Post a screenshot of the SWI Stacking Cable (for posterity):


    RCinFla also posted information (may be the same--I did not trace each wire):

    Bill, Thanks again for taking the time to research this topic. While I've yet to figure out the difference between the SWI and SWI/PAR cables
    I have, while rereading all associated previous posts I have realized that for parallel operation I would need the Paralleling Interface Module to pull this off. I have handled lots of old Trace/Xantrex equipment before and haven't come across the Interface module or I would have ended up with one. I guess at  this point I'll put this thread to rest.
    I really appreciate everybody's help With this, Mike McCormick
