AUXOFFS
Coding of date & time offset conforming to LEITCH CSD
–
5300 format with Auxiliary
Offset. The user data
are used for the date as described under “BBC”. Additionally
,
an offset is encoded in 30
–
minute increments. 6 bits in binary form are split into two
3
–
bit groups and are inserted into the reserved binary groups BG5 and BG7:
BG5
Offset, 3 lower bits
3 bits, LSB = bit 36
BG7
Offset, 3 upper bits
3 bits, LSB = bit 52
This allows an offset in the positive direction of up to 23 hours 30 minutes, or 47 half
hour steps (101111 in 6
–
bits binary form). Devices decoding these bits add this offset
to the time information of the time code. The date coded in the user data is not
coupled with that offset, i.e. the date changes at 24 o’clock of the time code.
Offset can be entered at
Aux
of the
Time Zone
configuration.
SMPTE 309M: YYMMDD
Date and time zone information, according to SMPTE 309M
–1999 “YYMMDD”
format.
SMPTE 309M: MJD
Date and time zone information, according to SMPTE 309M
–1999 “MJD” format.
Disable BGF
Check this checkbox to disable the use of the “Binary Gr
o
up Flags“ of the time
code, i.e. these flags will then be set to 0.
Generator
The time and the user data can receive start values:
Time
Preset of the time: HH:MM:SS:FF. Press the
Set Time
button to let the generator start
with this time
–
applicable only in the
START
or
FREE
method of operating.
User
“User“
(user data) denotes the eight binary groups of the time code. These are eight
digits with values in the range 0
–
9 and A
–
F.
Clicking
Set User
will transfer the preset to the time code generator
–
in whole or in
part dependent
on the “User Mode” selection:
•
in case of
‘Set User’ all eight digits will be set;
•
in case of any date format
only those places indicated as “U”
will be set.
Real
–
Time
You can set time and date of the internal real
–
time clock. This could be useful if there is no
real
–
time reference available or if the time has become inaccurate. This will set the buffered
clock of the Ethernet module as well.
Time
Enter a time (HH:MM:SS). Click
Set Real

Time
to force an update with this preset.
Date
Enter day, month, year (D, M, Y). Click
Set Date
to force an update with this preset.
