Thank you for the kind reply!
But I am having a little trouble.
1) the couplers don't seem to unlock
2) I can be sure which cable it is because of #1
So question: Can I just leave this box and use a longer ethernet cable to move the other boxes the 30 feet I need to go?
Are there different pin combos on e-net cables I need to worry about? I have had this happen before but on special installs...
thanks very much!
