Turn on the POWER switch. Position the TCG switch at [F-RUN]. Position the DISPLAY switch at [TC].

To externally lock the time code:

Follow the steps below.

1

2

3

4 Set the menu option GENLOCK to “EXT”.

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

5 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.

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

<Note>

When 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-SPX900E in recording mode before the sync generator stabilises.

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.

<Notes>

z To externally lock the AJ-SPX900E, 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.

z When using the MON OUT connector to output reference signals, position the OUTPUT SEL switch on the side panel at [CAM].
