S.S.F. data stored in the unitís memory can be written to the beginning of tape.

Precautions when writing S.S.F. data

•When S.S.F. data stored in the memory of the GY-DV550 is written to the beginning of the rewound tape, approximately 5 seconds of recorded video and/or sound will be erased at the beginning.

In the case of important recordings, leave 5 seconds or more of the tape unrecorded before starting recording.

•Writing of S.S.F. data should be done with the DC cable disconnected.

Operation
1. Press the STOP button to enter the stop mode.
2. Press the REW button while the LOG button is kept pressed.
•	The REW indicator blinks during tape transport in the
•	writing position.
	The LOG indicator lights while S.S.F. data are being
•	written to the tape.
	When writing to the tape is completed, the LOG indicator

About the Scene End Cue Up Function
 When the CONTINUE button is pressed while the LOG
	button is kept pressed in the stop mode, the tape winds
	to the S.S.F. data’s last OUT point, after which the unit
	enters the record-pause mode. (Scene End Cue Up)
	The FF button’s LED blinks during the Scene End Cue
	Up mode.
	Note:
Once a tape with recorded S.S.F. data is ejected and then
reinserted again, the previous data will be erased if new
S.S.F. data are recorded on the tape.

 When using the GY-DV550 as playback component
1.	Turn ON both units.
2.	Confirm that the VCR Setup Menu item No.126 INPUT
	SELECT is set to “CAMERA”(cA).
	* If set to “IEEE1394”, set it to “CAMERA” and then turn
	ON the power again.

3. Insert the videocassette.

4. Connect the DV cable.

*	Always connect the DV cable last.
		Memo:
	•	When the GY-DV550 is controlled through the DV
		connector, set the VCR Setup Menu item No.050
		REMOTE SELECT to “IEEE1394”.

 When using the GY-DV550 as recording component
1.	Turn ON both units.
2.	Set VCR Setup menu No. 257 AUDIO REF. SIGNAL LEV.
	For proper E-E audio output, set the VCR Setup Menu No.
	257 to the audio reference level of the tape on the player (-
	12 dB or -20 dB).
	Memo:
	When VCR Setup menu No. 126 INPUT SELECT is set
	to IEEE1394, No. 257 AUDIO REF. SIGNAL LEV setting
	cannot be changed.
3.	Set the VCR Setup Menu item No.126 INPUT SELECT to
	“IEEE1394”(iE).
4. Insert the videocassette.

10-6 Outputting S.S.F. Data
The S.S.F. data in the memory of the main unit or that recorded
at the beginning of the tape can be output via the REMOTE
connector using the RS-232C controller.
For how to make connections for this, refer to “Connecting a
PC” on page 71.
Operation
In the stopped condition, the GY-DV550 answers with the S.S.F.
data when it receives the RS-232C command D5h “S.S.F. DATA
SENSE” from the PC.

Operation

 When recording in the S.S.F. mode is completed, and the

cassette tape has not been taken out, the S.S.F. data stored

in the memory of the GY-DV550 are output when the RS-

232C command D5h is received.

 If the tape recorded in S.S.F. mode is ejected and then loaded

again, the GY-DV550 rewinds the tape to the beginning and

plays back for about 10 seconds when it receives the RS-

232C command D5h.

During the playback, the model lD data and reel number

recorded on the tape are read. If corresponding S.S.F. data

are found in the memory, these data are output.

If corresponding S.S.F. data are not found in the memory, the

tape is rewound to the beginning once more, and after about

20 seconds of slow playback the stop mode is entered.

During slow playback, if S.S.F. data are written at the

beginning of the tape, these data are read out, and after the

stop mode is entered the S.S.F. data are output.

However, the following functions may not work

depending on the component that the GY-DV550 is

connected to.

REC

FF (FWD search is possible) REW (REV search is possible)

•When the DV cable is connected for communication with another component, to stabilize the IEEE1394 output signal, the STILL mode is activated for a few seconds and the LED of the STILL button on the top section of the GY-DV550 lights when the mode is

switched to PLAY or x1 FWD search.

∗ The x1 FWD search only works during IEEE1394 control or RS-232C control.

•The operation method differs with the characteristics and specifications of the connected equipment. Even if connection is possible, operation or data communication may sometimes be impossible to perform.

Note:

5. Connect the DV cable.
*	Always connect the DV cable last.
	Memo:

•When recording while controlling the GY-DV550 through the DV connector from another component with DV connector, set the VCR Setup Menu item No.050 REMOTE SELECT to “IEEE1394”.

In this case, it takes approximately 2 to 3 seconds before recording starts on the GY-DV550.

•The audio recording level to the tape constitutes an input signal reference level regardless of setting the VCR Setup Menu No. 257 AUDIO REF. SIGNAL LEV.

When the GY-DV550 is used as camera, and a backup recording is made on another component via the DV connector, set the VCR Setup Menu item No.126 INPUT SELECT to “CAMERA”.

∗ If S.S.F. data does not exist, the 05h (NOT TARGET)

command is output.

If the above procedure is not performed correctly, the playback picture may be disturbed or the sound may fall out. If this happens, redo the connection by performing steps 1. to 4. described above.
