Chapter 4 Adjustments and Settings for Recording (continued)

To externally lock the time code

Follow the steps below.

1Turn on the POWER switch.

2Position the TCG switch at [F-RUN].

3Position the DISPLAY switch at [TC].

4Set the menu option GENLOCK to “EXT”.

This option can be found in the <GENLOCK> screen, which is accessible from the SYSTEM SETTING page.

5Supply 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.

From about 10 seconds after locking the time code generator stays locked even if the supply of external reference time code is discontinued.

<Notes>

zWhen the time code generator is externally locked, the time code instantly becomes locked with the external time code, and the counter displays the external time code value. Do not put the AJ-SPC700P in recording mode before the sync generator stabilises.

zWhen the IEEE1394 interface board (AJ-YAD800G, optional) is attached, it is not possible to synchronize with the time code entered via the TC IN connector if “1394” is selected for the menu option REC SIGNAL. The menu option REC SIGNAL is found in the SYSTEM MODE screen on the SYSTEM SETTING page.

Setting the user bits when the time code is externally locked

When the time code is externally locked only time data is locked with the time data of the external time code.

This means that the user bits may be set separately for each camera-recorder.

When “EXT” is specified for the menu option UB MODE, the user bits is also locked with the user bits of the external time code.

The menu option UB MODE can be found in the <TC/UB> screen, which is accessible from the MAIN OPERATION page.

To unlock the externally locked time code

Discontinue external time code supply, then position the TCG switch at [R-RUN].

Cautions in switching the power source from battery to external power supply

Connect the DC IN socket with the external power supply before removing the battery pack, in order to keep the time code generator energised. If the battery pack is removed first, there is no guarantee that the time code will stay externally locked.

External synchronisation of the camera when the time code is externally locked

When the time code is externally locked, the reference video signals input through the GENLOCK IN connector gen-lock the camera.

<Note>

To externally lock the AJ-SPC700P, as the master device, with more than one unit, the mode must be the same as that of the camera. Note that in a system using both interlaced and progressive scanning, there may be breaks in the video and time code.
