Jam Function - Fostex FR-2 Owner's Manual

The jam function of the internal time code generator allows taking over generating time code after the
generator locks to the external time code timing.
Using the jam function, even if time code connection is cut after lock is achieved, the internal time
code generator can run while keeping the timing. Therefore, even though the FR-2 is away from a
VTR, you can record audio (for newsgathering, etc.) to the FR-2 while striping time code in sync with
the VTR.
<Note>: The jam function is available only when the "Gen. Mode" menu item in the TC Setup menu
is set to "Free (Free Run)". If it is set to any other mode, the jam function does not work.
• To execute the jam function, the following condition must be satisfied.
1) External TC (from a VTR, etc) is fed to the [TIME CODE IN] connector.
2) The frame rate matches between external TC and the FR-2.
If it does not match, set the frame rate of the FR-2 appropriately. See page 9 for details about frame
rate setting.
3) The generator mode is set to "Free Run".
If it is not set to "Free Run", set it to "Free Run". See page 11 for details about generator mode
setting.
Besides the above, if necessary, you can set the jam mode via the "JAM Mode" menu item in the TC
Setup menu. By default, both the time value and userbit of the external time code are jammed.
However, you can change this setting to jamming only the time code value or only the userbit (see page
17 for details).
• Executing jam function
The following describes how to execute the jam function, assuming that the condition above is
satisfied.
1) While the unit is stopped, press the [ENTER] key to enter the MENU mode.
2) Use the [MENU] dial to select "TC Setup" and press the [ENTER] key.
3) Use the [MENU] dial to select the "Force JAM" menu item on page 3 and press the [ENTER] key.
The display now shows the Force JAM screen, where time code value, frame rate and userbit
information of the incoming external time code is shown.
The "JAM" icon points to a jammed item, which can be set by the "JAM Mode" menu item in the TC
Setup menu. In the screen example below, both the time code value and userbit are jammed.
4) Use the [MENU] dial to select "Force JAM>" at the bottom line and press the [ENTER] key.
After popping up "Force JAM! TC & Ubit", the display returns to page 3 of the TC Setup menu.
5) Disconnect the external time code from the [TIME CODE IN] connector.
The internal time code generator takes over generating time code and runs while keeping the
timing of the external time code.
