Synchronizing With The Time Code Of The Ieee1394; (Dv)-Connected Master Unit - JVC GY-HD200CHE Instructions Manual

PREPARATIONS FOR OPERATION
Synchronizing with the
Time Code of the IEEE1394

(DV)-Connected Master Unit

You can synchronize the time code when performing multi-camera recording. The internal time code generator will be synchro-
nized with the time code in the signal input from the IEEE1394 terminal. After synchronization (slave lock), the internal time code
generator continues to run even if the IEEE1394 cable is disconnected.

You can use the GY-HD250U, GY-HD251E, GY-HD110U, or
GY-HD111E as a slave unit.
Connections
Connect the master unit and the slave unit with an IEEE1394
cable.
Settings and Operations
• Master unit (GY-HD100U/GY-HD100E/GY-HD101E/GY-
HD110U/GY-HD110E/GY-HD111E/GY-HD250U/GY-
HD251E)
1.
Set the IEEE1394 switch on the left side to [DV].
2.
Set to Camera mode.
3.
Set the recording format to DV-60I or DV50I.
4.
Set the TC GENE. switch to [FREE].
• Slave unit (GY-HD250U/GY-HD251E/GY-HD110U/GY-
HD111E)
1.
Set the IEEE1394 switch on the left side to [DV].
2.
Set to VTR mode.
3.
Check that the camera image from the master unit is input.
4.
Set TCG SOURCE in the TC/UB/CLOCK menu screen to
INTERNAL. (GY-HD250U, GY-HD251E)
5.
Set the TC GENE. switch to [FREE] and the TC DISPLAY
switch to [TC].
6.
Set to STOP mode or EJECT mode.
7.
Press the STOP button for 1 second.
• The DV input time code data from the IEEE1394 termi-
nal is displayed in the status display. (When status is in
magnified size, characters are displayed.)
8.
Press the USER1 button to begin slave lock.
(To skip slave lock, press the USER3 button and clear
the status display.)

Check that the time code that is synchronized with the
master unit is running.
10.
Disconnect the IEEE1394 cable.

The slave unit finally returns to Camera mode.
MEMO
Slave lock cannot be performed in the following
instances.
• Slave unit is in CAMERA mode
• Slave unit is in VTR mode and there is no DV signal
• The TC GENE. switch on the slave unit is not set to
FREE
• HDV format
If slave lock is performed in DV format and is then
switched to HDV format, frame digit may deviate.
If power is turned off, slave lock is disabled. Perform
slave lock operation again.
Slave lock cannot be performed for UB (User's bit).
If the frame rate for the master unit and slave unit is not
synchronized, it will not run properly. Synchronize frame
rate before using.
If DROP/NON DROP is not synchronized, it will not run
properly. Synchronize DROP/NON DROP before using.
Synchronizing with an Exter-
nal Time Code Generator
Synchronize the built-in time code generator with the
SMPTE/EBU-compliant LTC time code, which is input from
the [TC IN] terminal. After synchronization (slave lock), the
built-in time code generator continues to run even if external
time code are not input.

Connection
Input external synchronization signal to the external time
code generator and the GENLOCK/AUX IN terminal of this
device.
Use BB signals or Tri-sync HD signals as the external syn-
chronization signals.
CAUTION
When the power switch is turned on while the external syn-
chronization signal is input, a vertical vibration occurs for a
few seconds. This is not a malfunction.
Input SMPTE/EBU-compliant LTC time code signal to the
P /TC IN terminal.

Set the [GENLOCK/AUX IN] switch to GENLOCK.
Set the [P P /TC] switch to TC.

Set TCG SOURCE in the TC/UB/CLOCK menu screen to
EXTERNAL.
Set the LCD screen or viewfinder to STATUS 1 screen dis-
play.
Or set the LCD screen to enlarged status display screen.

Operation
1.
Set the external time code generator and operate it.
• The built-in time code generator synchronizes with the
input external time code data.
"L" lights up in the STATUS 1 screen of LCD screen or
viewfinder. "L" also lights up when the LCD screen is in
enlarged character display.

• "L" blinks when the time code cannot be synchronized.
2.
The built-in time code generator continues to run even if
the external time code generator is disconnected after
synchronization.
CAUTION
If a time code generator is connected or disconnected dur-
ing recording, servo lock will be disturbed.
When connecting multiple devices and assigning one
as the master unit and others as slave units
If there is only one slave unit, connect as shown below.
If there are multiple slave units, input external synchroniza-
tion signals to all GENLOCK/AUX IN terminals from the syn-
chronization signal generator.
