I am trying to get everything up and running. I seem to be a little confused on a few things. If anyone can shine some light it would be great! I have bought a few Sentinel's pxm-2 power expander relay things that run off 240volt power supply. They say that I can interconnect two of these together. Question is how? I would of thought that it would come with this interconnect cord but I have three of them and only cord I got was the trigger cord. I searched the shit out of this online with no luck. Best I can come up with is I have to use my second PXM-2 trigger cord as the interconnect cord? Plug jack end into the interconnect and then plug trigger plug end into one of the two universal type 240 volt receptacles. Does this sound right? I did notice that the trigger cable is rated for 100-240volt.
