Step 3 Set the hop sequence. For details, please refer to “Frequency Hop

Sequences” on page 38.

Step 4 Set the synchronization method. Merlin Mobile offers three synchronization

methods for piconet recording:

• Sync & Record — for more information about this method, please see

“Make a Manual Sync & Record Piconet Recording” on page 28.

• Passive Sync & Record — for more information about this method, please

see “Make a Manual Passive Sync & Record Piconet Recording” on

page 29.

• Page Sync & Record — for more information about this method, please

see “Make a Manual Page Sync & Record Piconet Recording” on

page 27.

Note: If the hop sequence option is set to Reduced Hop or Single Frequency, then

the Sync Method is set to Test Mode and cannot be modified by the user.

Step 5 Set additional settings. For details, please see “Additional Settings” on

page 39.

Step 6 (Optional) Enable CATC debug file. When this option is selected, Merlin

Mobile will create a file that can be used by CATC Support to aid in

debugging. This option should always be disabled unless otherwise directed

by CATC personnel.

Step 7 Click OK to use the settings and close the Recording Options dialog

-or-

Continue configuring the recording options on the General, Events and

Actions tabs.

Note: You may also save the settings as a Recording Options (.rec) file. This will allow you to load the file

whenever you want to use those settings.

Frequency Hop Sequences

In order to be able to synchronize with other devices and record piconet traffic, Merlin

Mobile needs to know the frequency hopping sequence that the piconet is using.

The hopping sequence that is set here is used only for initial synchronization to the piconet.

Merlin Mobile can dynamically follow test-mode initiated changes to the hop sequence with

one limitation: Merlin Mobile cannot dynamically follow a piconet that changes from a

test-mode hop sequence to the 79-hop standard mode.

Merlin Mobile supports these hop sequences:

• 79 Hops Standard

• Reduced Hop — Restricts Merlin Mobile to the five hop frequencies of the Bluetooth

test mode, as described in the Bluetooth specification. When it is selected, the Sync

Method is set to test mode and cannot be modified by the user.
