Chapter 3: SYNC I/O Hardware and Software 29
Time Code Window
The time code display mirrors the LED Time
Code Display on the SYNC I/O front panel, dis-
playing (in hours:minutes:seconds:frames) the
time code address of the current positional ref-
erence.
When SYNC I/O 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 SYNC I/O clock reference.
Sample Rate
This control selects SYNC I/O sample rate (or
the Pro Tools session sample rate, if applicable).
Pull Rate
This control Enables Pull Up or Pull Down for
the current sample rate.
Word Clock Out
This control configures the SYNC I/O 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 SYNC I/O positional refer-
ence.
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 SYNC I/O
Setup software utility in relation to SYNC I/O
and external devices, as follows:
Resolver Locked Lights when SYNC I/O is
locked to the chosen external clock reference, or
to its Internal clock reference.
Speed Calibration Lights when SYNC I/O system
clock and all output clocks are at a frequency
that corresponds with the chosen sample rate.
Capable of indicating mismatch of pull-up, pull-
down and frame rate.
Regenerator Locked Lights when SYNC I/O is re-
generating time code at its video, LTC, and MTC
outputs locked with the incoming positional
reference source. Also lit whenever SYNC I/O is
generating time code internally.
Connected to SYNC I/O Lights when the SYNC
Setup window is the front-most window and is
communicating with SYNC I/O.
Waiting for SYNC I/O Lights when the SYNC
Setup window is the front-most window and is
unable to communicate with SYNC I/O.
Port Relinquished Lights when the SYNC Setup
window is not the front-most window or is un-
able to allocate a serial port with which to com-
municate with SYNC I/O.

teristics, see “Status LEDs” on page 25.
