3.6.4.
In Master-, Repeater- and Monitor Mode the Parameter Port is differently configured than in Slave Mode. The
pins serve as output channels for additional support signals or become set to high impedance state. There is
no input function associated with the Parameter Port pins.
Following support signals are provided at the Parameter Port in Master-, Repeater- and Monitor-Mode.

Receive Clock is provided to simplify external processing of Manchester-II-coded output data at LED1 pin.
The availability of a new AS-i telegram bit at LED1 is signaled by a rising edge of receive clock so that the
received data can simply be clocked into a shift register. The output signal is active high.
Power Fail signals a breakdown of the AS-i supply voltage. The output signal is active high. Further
information regarding the Power Fail function refer to chapter 3.8 Fault Indication Input Pin FID.
Receive Strobe – Slave Telegram is generated after every correctly received AS-i slave telegram. The output
signal is active high.
Receive Strobe – Master Telegram is generated after every correctly received AS-i master telegram. The
output signal is active high.
The generated pulse width is 1.0µs for both Receive Strobe signals at the output drivers (Hi-Z time). The
resulting signal pulse width depends on the external pull-up resistor and the load circuit.
