Merlin II Protocol Analyzer User’s Manual
CATC
SW Version 2.50
This value specifies how long Merlin II should perform the Inquiry process 
for the General (unlimited) and Dedicated (limited) recording modes. After 
the specified time has elapsed, Merlin II will illuminate the trigger light on 
the front of the analyzer.
Initial De-whitening State
De-Whiten On -- Turns on De-Whitening
De-Whiten Off -- Turns off De-Whitening
This setting controls the initial de-whitening state.
If " De-Whitening Off" is selected, Merlin II will try to synchronize without 
de-whitening the received packets, and assume that they were transmitted 
un-whitened.
If " De-Whitening On" is selected, Merlin II will use received packets to try 
to synchronize while it is performing a de-whitening process that complies 
with Bluetooth specifications.
This setting controls the initial state for the synchronization. After Merlin 
II has synchronized to the piconet, it will try to follow changes in the 
whitening scheme and dynamically track whitened and non-whitened 
traffic.
In case a recording was stopped and you want to restart a recording session 
of the same piconet, you should remember that Merlin II might still be 
synchronized to the same piconet. As Merlin II dynamically follows 
whitening scheme changes, it will not use the initial de-whitening state. 
However, if you want to force an initial de-whitening state, check the "Force 
Re-Synchronization" flag.
Sync Window
The Sync Window slide bar controls the amount of time that Merlin II 
should wait between receiving an Inquiry Response (which will cause the 
Sync LED to blink) and detecting Master-Slave piconet traffic (which will 
cause the Sync LED to turn solid.) 
A "Narrow" setting means that the wait time will be minimal, a "Wide" 
setting means it will be "maximal." The default is "Narrow" and this is 
suitable for most recordings. However, if significant drift occurs between 
Merlin II’s clock and that of the Master, Merlin II may not be able to sync 
properly to the piconet. Under these conditions, you should move the slide 
bar towards the "Wide" Setting. The slide bar has five discrete settings.
