•
For every telegram sent out on KNX TP, MECip-Sec waits for an acknowledgement on
the TP line. When the receiver was busy (BUSY) or received an incorrect telegram
(NACK) or MECip-Sec didn´t receive an acknowledgement (missing IACK), LED 2 is
lighting red to show a transmission error exists on the line.
LED 2 Bus State KNX TP is continuously blinking green. Why?
