4.2.7.3.3. Bit Synchronizer Mode
The Bit Synchronizer can be programmed to operate either in the standard mode (standard Bit Synchronizer) or
the extended mode (phase-locked to the BPSK sub-carrier). The extended mode is available for low bandwidth
applications with the Viterbi license only:
Registry path: HKEY_LOCAL_MACHINE\SOFTWARE\In-snec\CortexCRT\SetDefault\Preferences\Tmux
(x = TM chain number)
Keyword: BSCoherent
Default setting at delivery: 0 (standard mode)
Enter 0 (standard mode) or 1 (Bit synchronizer phase-locked to the BPSK sub-carrier).
4.2.7.3.4. Removal of the R-S Codeblock and Synchronization Word
To customize the telemetry message (Annex 1, STI 100013_CRT, section 2.4.4) with the R-S decoding license:
Registry path: HKEY_LOCAL_MACHINE\SOFTWARE\In-snec\CortexCRT\SetDefault\Preferences\Tmux
(x = TM chain number)
Keyword: RsCode
Default setting at delivery: 0 (transmit the R-S codeblock & SW)
Set bit 0 to 0 for transmitting the R-S code and the SW or 1 for removing the R-S code and the SW.
Set bit 1 to 0 for standard Frame Check result field (offset 6) or to 1 for reporting the number of errors corrected
by the R-S decoder in byte 1 of the Frame Check Result field
4.2.7.3.5. Removal of the Synchronization Word for Frame Checking
To include or exclude the synchronization word for CRC or Check Sum verification
Registry path: HKEY_LOCAL_MACHINE\SOFTWARE\In-snec\CortexCRT\SetDefault\Preferences\Tmux
(x = TM chain number)
Keyword: CRCwithoutSW
Default setting at delivery: 0 (SW included in CRC or Check Sum checking)
Set the keyword to 0 (SW included) or 1 (SW excluded)
4.2.7.3.6. Removal of Dummy Frames for TM Storage
To remove or not the dummy frames in telemetry data storage files
Registry path: HKEY_LOCAL_MACHINE\SOFTWARE\In-snec\CortexCRT\SetDefault\Preferences\Tmux
(x = TM chain number)
Keyword: NoDummy
Default setting at delivery: 0 (Dummy frames stored on the disk)
Set the keyword to 0 (Dummy frames stored) or 1 (dummy frames not stored)
