INPUT
Using the RS-232C remote control (AJ-A250), which is available as an optional accessory, two
units—a player VTR and a recorder VTR—can be controlled directly from the controller to enable
speedier and more efficient assemble editing, insert editing and other editing jobs.

Read the operating instructions of the AJ-A250 carefully.
Operation:
Use the RS-232C remote control to control both the player VTR and recorder VTR.
Preparation:
OAs shown in the figure below, connect the player VTR and recorder VTR to the RS-232C
remote control.
OSet the INPUT SELECT switch to the position which corresponds to the connection with the
player VTR.
S-VIDEO:When connected to the S-VIDEO IN and AUDIO IN connectors
LINE:When connected to the VIDEO IN and AUDIO IN connectors
OSet the LOCAL/MENU/REMOTE switch to the REMOTE position.

The disturbances in the pictures during preview can be alleviated by inputting a black burst
signal or other reference signal to the REF VIDEO input connectors of the player VTR and
recorder VTR.

When the AG-A571 is to be used as the remote control, select D230 as the setup menu item
No.205 “232C ID SEL” setting.  (See page 30)
The unit can be used as the player VTR.

Audio editing functions
The information (setup menu item No. 700, 701) concerning the selection of the joining method
used at the edit points is recorded during digital audio editing, and this information is detected
during playback so that the edit points can be processed automatically.
This applies only when AUTO has been selected as the playback fade selection (setup menu
item No.702) setting.

OWhen CUT has been selected for the playback fade selection (setup menu item No.702),
cutting will be performed for all the joins at the edit points.
OWhen FADE has been selected for the playback fade selection (setup menu item No.702), V-
fading is performed for all the joins at the edit points.
OWhen only one channel has been selected for the sound to be inserted during insert editing,
the sound of the channel which has not been selected will be muted.

V-fading
When CUThas been selected as the joining method at the edit points.
(setup menu item No.700, 701)
Noise may appear here at the joins in the edit points.
When FADEhas been selected as the joining method at the edit points
(setup menu item No.700, 701)
V-fading is performed instantaneously to suppress the
noise. 
						

							37
First Edit Function (Preparing the editing tape)
The CTL (control) signal must be recorded ahead of time onto the editing tape.  The method
used to record it differs depending on whether assemble editing or insert editing is to be
performed.
The “E-00” servo lock error appears on the tape counter when insert editing is performed for a
tape on which the CTL signal has not been recorded.
When insert editing is performed, the CTL signal must be recorded ahead of time.

When first edit is to be performed, operation can be conducted by connecting the RS-232C
remote control (AJ-A250), which is available as an optional accessory.  However, control using
the RS-232C interface (EFE command) can also be exercised from a computer.
(See page 50)

In the case of a tape for assemble editing, the CTL signal is recorded at the beginning of where
the recording is to be commenced.

(3) Receiving format (VTR computer)
The VTR responds to a send command with the
format data below.
1. First, the VTR returns the data indicating
whether the command from the computer was
received properly.
1) If the communication was error-free, the VTR
returns the ACK (Acknowledge) data.
[ACK]
06H
2) If there was a problem in communication, the
VTR returns the data starting with NAK (Negative
Acknowledge).
If the VTR was in the process of sending the
data when the computer sent its command, the
VTR returns NAK after it completes the sending
of the data.
The VTR now destroys all the received data with
errors.

2. Next, after ACK is returned when the
communication was error-free, the data is
returned in the following format by the
operation of the VTR.
1) The format of the response (return) data in cases
where commands from the computer were
properly received by the VTR is as follows.

Check the operation carefully before use when
controlling the VTR from a personal computer, etc.
It is recommended to monitor VTR status information
while controlling the VTR in this way.
