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 Position the DISPLAY switch at [TC]. 4 Set the menu option GENLOCK to "EXT". This option can be found in the screen on 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. Notes 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 begin recording in the few seconds it takes for the synch generator to stabilize. Be sure to enter the non-drop-frame time code to externally lock the time code in the 24P, 24PA or 24PN (Native) mode. Externally locking the drop-frame time code is not permitted. Video quality may be degraded momentarily while externally locking to adjust the 5-frame cycle. This is not abnormal. While recording data in the 24P, 24PA, or Native modes, it is impossible to lock the time code externally. Lock it before recording. Note also that if the unit is used with PRE REC MODE set to "ON" in any of the 24P, 24PA or Native modes, changing the time code from Rec run to Free run or slave locking the time code before recording may result in a flickering video or a stopped code being recorded. In the 1080/23.98PsF mode, the 23.94 Hz non-drop frame time code should be supplied. In the 1080/24PsF mode, the 24 Hz non-drop frame time code should be supplied. Setting the user bits when the time code is externally locked When the TCG switch is positioned to [F-RUN], only the time code is locked to an external time code. To lock the user bits to an externally input value, the UB MODE and VITC UB MODE menu options must be set to "EXT" and "USER/EXT", respectively. The menu option UB MODE and VITC UB MODE can be found in the screen on 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 energized. If the battery pack is removed first, there is no guarantee that the time code will stay externally locked. External synchronization 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 To externally lock the unit, 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. When using the MON OUT connector to output reference signals, position the OUTPUT SEL switch on the side panel at [CAM]. Superimpose of time codes To display the time code in the viewfinder or the LCD monitor when recording or during playback, set TC in to "TCG", "TCR", or "TCG/TCR". To include the time code indication in the MON OUT or HD SDI A · B outputs, set the MON OUT CHARACTER switch to [ON], and set HD SDI A · B CHAR to "A", "B" or "BOTH" from the screen using the menu. To display the time code while the color bar is displayed, set TC ON COLOR BAR in to "ON". 72 Adjustments and Settings for Recording: Setting Time Data
