4.2.7.5.5. Extended Idle Patterns (1 to 255)
To define the extended idle patterns.
Registry path: HKEY_LOCAL_MACHINE\SOFTWARE\In-snec\CortexCRT\SetDefault\Preferences\Tcu
Keyword: ExtIdlex (x = 1 to 255)
Default setting at delivery: 0
Configure the value of the extended Idle pattern, up to 8192 bits. The index of the pattern is selected owing to the
8 MS bits of the Idle pattern configuration parameter. The extended idle pattern is entered as a series of
hexadecimal values, using the Binary Value feature of the Registry Editor. When the length of the extended idle
pattern is not a multiple of a byte, the value must be left-justified and the last byte is padded with zeros.
4.2.7.5.6. Extended Preamble Patterns (1 to 255)
To define the extended preamble patterns.
Registry path: HKEY_LOCAL_MACHINE\SOFTWARE\In-snec\CortexCRT\SetDefault\Preferences\Tcu
Keyword: ValPreax (x = 1 to 255)
Default setting at delivery: 0
Configure the value of the extended Preamble pattern, up to 8192 bits. The index of the pattern (x) is selected
owing to the 8 MS bits of the Preamble pattern configuration parameter. The extended preamble pattern is
entered as a series of hexadecimal values, using the Binary Value feature of the Registry Editor. When the
length of the extended preamble pattern is not a multiple of a byte, the value must be left-justified and the last
byte is padded with zeros.
4.2.7.5.7. Always Idle
To define the minimum idle length (in bits) inserted between two clear TC.
Registry path: HKEY_LOCAL_MACHINE\SOFTWARE\In-snec\CortexCRT\SetDefault\Preferences\Tcu
Keyword: AlwaysIdle
Default setting at delivery: 0 (Idle length in bits)
If this key is present, then an IDLE of the length defined by this key will be inserted systematically between two
clear TC.
4.2.7.5.8. Enable primary acknowledgement
To enable primary acknowledgement:
Registry path: HKEY_LOCAL_MACHINE\SOFTWARE\In-snec\CortexCRT\SetDefault\Preferences\Tcu
Keyword: PrimaryAck
Default setting at delivery: 0
Enter 1 to enable primary acknowledgement.
