rameter values:
• "A LEAd b": Bi-Phase: FWD = A leads B
• "b LEAd A": Bi-Phase: FWD = B leads A
• "r–n–d LO": Tach: FWD = B is Low
• "r–n–d HI": Tach: FWD = B is High
Press Set.

From the SYNC Setup software utility
(Windows only):
In the SYNC SEtup Bi-Phase/Tach Parameters
1
section, choose one of the following settings
from the Wiring pop-up menu:
• Bi-Phase: FWD = A leads B
• Bi-Phase: FWD = B leads A
• Tach: FWD = B is Low
• Tach: FWD = B is High
Click Set.

Bi-Phase/Tach Pulses-per-frame (PPF)
There are several different standards for the
number of pulses-per-frame output by Bi-Phase
or Tach devices. You can set the SYNC periph-
eral to operate from 2 to 254 pulses per frame
from Pro Tools, from the SYNC peripheral front
panel, or using the SYNC Setup software utility's
Pulse Per Frame setting (Windows only). The
setting should match the PPF rate of the external
device's Bi-Phase/Tach encoder.

To set the pulses per frame value for a
Bi-Phase/Tach signal:
From Pro Tools:
Choose Setup > Peripherals and click Syn-
1
choronization.
In the Bi-Phase/Tach Pulses/Frame field, enter
2
a value from 2 to 254.
Click OK.

From the front panel:
Press Set, and use the Up and Down switches
1
to display Bi-Phase/Tach Pulses Per Frame
("bIPH PPF").
Press Set. The LED Time Code Display displays
2
the current PPF value.
Use the Down and Up switches to scroll
3
through the parameter values (from 2 to 254
pulses per frame). Holding either switch will
scroll at a faster speed.
Press Set.

Pulses/Frame field,
Click Set.

Bi-Phase Position Trimming
While using bi-phase as your positional refer-
ence, you can trim the Bi-Phase-to-time code
translation at any time. Each press of the Up
switch will advance the time address one frame.
Each press of the Down switch will retard the
time address by one frame. Remember how
many presses you've accumulated so that you
can go back and trim the starting address you
previously programmed.
