TKB-720 Pin 13
Posted: Mon Aug 05, 2013 4:55 pm
I just purchased a TKB-720 base station. I am trying to to get a cos detector from pin 13. Right now I get 4.75v all the time from pin 13. I know that it is suppose to be active high and goto 3.5v when receiving a signal. I don't have a service manual to see how I would do that.
Any help would be appreciated.
