Connecting a 2nd KLM on a 7324, & thought it was a snap, but ?? I can't find the hookups in the manual. I know I only need 1 pwr supply. Do I run the "tip & ring" in on the same line cord on 4-5, & pwr on 3-6? Help me out here please! & where can I find the instructions for the next time I run into this?
