Registry Configuration
There is a few user-defined Registry keys that controls the features under:
[HKEY_LOCAL_MACHINE\SOFTWARE\In-snec\CortexCRT\SetDefault\Preferences\TmuX]
Registry Key Type Description
UtoaScfPllBw
(CRT 6.18)
DWO
RD SCF PLL bandwidth
in units of 1/1000 000 * Bitrate
UtoaStationId
(CRT 6.18)
DWO
RD Station Id for the measurements return message.
UtoaUserField
(CRT 6.18)
STRIN
G Defines the fields that are to be extracted from the telemetry frame and
added to the measurements return message.
Syntax : a

first bit that follows immediately the synchronization word has the
position 0.

: size of the i

UtoaScfPllBw is used to define very narrow PLL bandwidth compatible with the expected measurements
accuracy.
UtoaStationId is used to define per TT&C station a unique ID in order to identifiy from the return message for
which station the measurements belong to.
UtoaUserField permits to add to the return message some useful fields within the telemetry frame such as
counters to identify and correlate measurements between stations.

TCP/IP Interface
Refer to §2.4.2 of document STI100013 for the TCP/IP request and return messages.
Also Cf. status at offset 49 of the “Telemetry Unit Table” at §2.2.2.10 of document STI100013 to check wether
the UTOA processing unit is locked onto the signal or not.
