I'm going to post this here so that I can find it the next time that I need to know. The SR-55 manual shows that pin 5 of the RJ12 port is TXD0-A-Out and pin 6 is TXD1-B-Out. I always either call tech or trial and error to determine which one is positive and negative. So for future reference: TXD0-A = + positive TXD1-B = - negetive
