 |Lead Out Time|The Pronto decoder needs to know how long silence should be counted as the end of a signal. If the protocol has very long pulse spaces within a message this may have to be extended from the default 9000 micro seconds.|\\

 ===== Audio Settings =====
 When Audio input is used, the ProtocolAnalyzer constantly samples the analog input signal, trying to recreate any digital pulses found in the signal. The so called //flank detector// uses a quite simple algorithm to find the flanks of the pulses:
@@ Line 30: / Line 31: @@
 In the example //Flank Swing// was set at 50 and //Flank Length// set to 3, so when the signal changed more than 50 over 3 samples, the flank was detected (see the blue line). Note that the signal changed more than 50 in the following samples as well, but since this was within //Flank Holdoff//, this was not counted.
-The parameters of the flank detector are configured in the Audio Settings Dialog. Nothe that the **NetHomeServer** uses the same flank detector, so the settings you find good here can be used in the the NetHomeServer as well.

 |Burst Length comp.|Many receivers of RF and IR signals are a bit "slow" in detecting the start of a mark pulse (burst). The result is that mark pulses are detected as a bit shorter then they are and space pulses a bit longer. This setting can compensate for this behavior|\\

+===== CUL Settings =====
+The CUL device is a programmable RF-transceiver on a USB stick. See [[http://busware.de/tiki-index.php?page=CUL | www.busware.de]] for details on the device.
