To select Auto LTC/VITC for positional reference:
From Pro Tools:
 In the SYNC Setup section of the Session Setup
window, select Auto LTC/VITC from the
Positional Reference pop-up menu.
From the front panel:
 Press the Positional Reference switch until
both the LTC and VITC LEDs are simultaneously
lit (this indicates Auto LTC/VITC).
From the SYNC Setup software utility
(Windows only):
 Select Auto Switch LTC/VITC from the SYNC
Setup Positional Ref pop-up menu.
Serial Time Code
SYNC peripherals provide 9-pin ports that allow
MachineControl-enabled systems to remotely
control or follow external 9-pin transports
through the use of serial time code.
For MachineControl-equipped Pro Tools sys-
tems, serial time code from either 9-pin port can
be used for positional reference.
To use Serial Time Code as the SYNC peripheral
positional reference:
 In the SYNC Setup section of the Session Setup
window, select Serial Time Code from the Posi-
tional Reference pop-up menu.
Bi-Phase/Tach
Bi-Phase/Tach signals are clock reference sig-
nals, and do not contain positional information
of their own. However, they do contain enough
information for SYNC Peripherals to calculate
positional information.
To calculate positional reference from
Bi-Phase/Tach, the SYNC peripheral must be
given a starting frame address and a specific
pulses-per-frame value. Each of these related set-
tings are explained in the following sections.
To use Bi-Phase/Tach for positional reference:
1 Do one of the following:
From Pro Tools:
•In the SYNC Setup section of the Session Setup
window, select Bi-Phase from the Positional
Reference pop-up menu.
From the front panel:
• Press the Positional Reference switch to select
Bi-Phase.
From the SYNC Setup software utility
(Windows only):
•Select Bi-Phase/Tach from the SYNC Setup Po-
sitional Ref pop-up menu.
2 Continue by setting the starting frame as de-
scribed in “Bi-Phase/Tach Starting Frame” on
page 47, and setting other Input Signals options,
as appropriate.

Auto Switch LTC/VITC, see “Auto-Switch
LTC/VITC” on page 72 in Appendix A.
