TK. Posted September 11, 2010 Report Share Posted September 11, 2010 Hi, without Optocoupler, led (TEST IN3) still lit is normal??? yes, because the LED will be supplied through the pull-up resistor R6 I put a led direct into J13 whit anode in +, and catode in -. ok. led flicks whith midi in. but if i put it in pin 2 and 3 of optocoupler (anode in 2, cathode in 3). led dont flicks. Is Normal? yes, because the optocoupler consumes power. Best Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
