Time Code Window
The time code display mirrors the LED Time
Code Display on the SYNC HD front panel, dis-
playing (in hours:minutes:seconds:frames) the
time code address of the current positional refer-
ence.
When the SYNC HD is reading odd-numbered
fields, the separator changes from a normal co-
lon (:) to a period (.); when it’s reading even-
numbered fields, the punctuation returns to a
colon (:). Odd/even status is only available while
reading VITC, and only when VITC is within a
speed range from zero to about 50% of playback
speed.
Clock Reference
This control selects the SYNC HD clock refer-
ence.
Sample Rate
This control selects the SYNC HD sample rate
(or the Pro Tools session sample rate, if applica-
ble).
Pull Rate
This control Enables Pull Up or Pull Down for
the current sample rate.
Word Clock Out
This control configures the SYNC HD Word
Clock Output between 256x (Super Clock) and
the current session rate (1x at 44.1 kHz, or 1x at
48 kHz). Only Legacy audio interfaces require
256x Super Clock.
Positional Reference
This control selects the SYNC HD positional ref-
erence.
Frame Rate
This control selects the frames-per-second (fps)
rate of external (or internally generated) time
code.
Status Display
This display shows the current state of the SYNC
Setup software utility in relation to the
SYNC HD and external devices, as follows:
Resolver Locked
Lights when the SYNC HD is
locked to the chosen external clock reference, or
to its
Internal clock reference.
Speed Calibration
Lights when the SYNC HD
system clock and all output clocks are at a fre-
quency that corresponds with the chosen sam-
ple rate. Capable of indicating mismatch of pull-
up, pull-down and frame rate.
Regenerator Locked Lights when the SYNC HD
is regenerating time code at its video, LTC, and
MTC outputs locked with the incoming posi-
tional reference source. Also lit whenever the
SYNC HD is generating time code internally.
Connected to SYNC I/O Lights when the SYNC
Setup dialog is the front-most window and is
communicating with the SYNC HD.
Waiting for SYNC I/O Lights when the SYNC
Setup dialog is the front-most window and is
unable to communicate with the SYNC HD.
Port Relinquished Lights when the SYNC Setup
dialog is not the front-most window or is unable
to allocate a serial port with which to communi-
cate with the SYNC HD.

teristics, see “Status LEDs” on page 25.
