Externally Locking the Time
Code
The time code generator built into your AG-HPX500P/
E may be locked with an external generator. It is also
possible to lock an external time code generator with
the internal generator.
Connections for externally locking the
time code (examples)
As illustrated, both the reference video signals and the
time code must be input.
■
Example 1: Locking the time code with
external signals
TC IN

GENLOCK IN
<Note>
• In addition to an HD Y reference signal, a composite
video signal can also be input as reference signal.
■
Example 2: Connecting two or more AG-
HPX500P/Es with one another,
with one being used as the
reference device.

<Note>
• On all connected devices, set the setting menu TC
VIDEO SYNCRO (OUTPUT SEL screen) to TC IN, GL
SELECT (OTHER FUNCTIONS screen) to COMPOSITE
and CMPNT/SDI SEL (OUTPUT SEL screen) to AUTO.
• Setting the setting menu TC VIDEO SYNCRO to TC IN
will supply the time code via TC IN to the next slave
device without delay.
To externally lock the time code
Follow the steps below.
1
Turn on the POWER switch.
2
Position the TCG switch at [F-RUN].
3
Set the COUNTER button to TC.
4
Supply a phase-relationship reference
time code (that conforms to the time
code requirements) and reference
video signals to the TC IN and
GENLOCK IN connectors, respectively.
• Now the built-in time code generator is locked with
the reference time code.
• When locked to an external time code generator, the
time code is at all times locked to the external time
code, which is displayed as a highlighted value on
the counter indicator. Do not engage the recording
mode during the few seconds it takes for the sync
generator to stabilize.
• Once a slave relationship is established, the TC IN
and GENLOCK IN connectors stay in slave status.
Note that the following events release slave status.
• When TC PRESET is performed
• When CAMERA mode and MCR mode are switched
• The power is turned off
• The time code mode is switched
• The TCG switch is set to R-RUN
* The slave function locks the time code to the TC IN
input and the device will use this time code even if
time code input should subsequently cease.
Setting the user bits when the time
code is externally locked
To externally lock user bits, set the setting menu TC IN
UB REGEN (RECORDING SETUP screen) to ON.
Regardless of an F-RUN or R-RUN setting of the TCG
switch, the time code is slaved to user bit values input
to the TC IN connector.
For details, refer to [Setting Time Data] (page 58) and
[Setting user bits] (page 60).
