Sending (DUMP)and loading (LOAD)edit data to an external component
RS-232C
The edit data stored in the EDL memory can be sent
to and loaded from an external component using the
EDL connector on the unit’s rear panel.
Outputting data to a computer, for instance, and
loading data from a computer enables a wide range of
systems to be run and managed in the following ways.OData can be edited off-line by the unit, and the edit
data can be used by an on-line system.
OThe edit data can be stored on a hard disk or floppy
disk.
OThe edit data can be checked by displaying it on a
computer monitor or by printing it out.

Loading edit data from an external
component
Loading is completed when all the edit data inside
the computer has been sent.
Alternatively, it is completed when the EDL
memory is full.
To stop loading at any time, press the ALL STOP
button.
1Use the same communication protocol settings for
the external component as for the unit.  The unit’s
protocol settings can be selected using setup
menu item No.205 through No.208 and No.270.
(Factory settings:
Baud rate: 9600 bps, Data length: 8 bits,
Stop bit: 1 stop bit, Parity: odd,
Flow control: None)
The external component (personal computer, etc.)
protocol settings are performed using the switches
and RS-232C setting commands (MODE
command and SPEED command).

Sending (DUMP)and loading (LOAD)edit data to an external component
Concerning the EDL format
Either the AG-A850 format or CMX340 format can be selected as the data format when edit data is to be sent to
a personal computer or other external component.
Select the format using the setup menu item No.271 (EDL FORMAT).
$AG-A850 format
Since all the edit data in the EDL memory is sent in this format, the edit data can be completely restored when
data which was sent from the unit is loaded again into the unit.  However, if data which was prepared with ON
selected as the setup menu item No.374 (EDL AUTO CLR) setting is to be loaded, it must be received at the
same ON setting.
Since the nature of the EDL format makes it impossible to differentiate between audio split data and video split
data in split edited data, the AUDIO SPLIT setting is what is normally used for such data.

OThe following restrictions apply when data edited by the AG-A850 is input to the unit.
Event number:Event numbers are ignored, and up to 200 events are received in sequence from the
first event.
Reel number:All reel numbers are received as “0001.”
Effect type:Only cut-edited events are received.
Slow-motion editing:Only events with 0a
(STILL) speed data are received with slow-motion editing.
OThe following restrictions apply when data edited by the unit is input to the AG-A850.
Editing mode:TC inserts are ignored.

C: Cut (cut is the unit’s only option)

Sending (DUMP)and loading (LOAD)edit data to an external component
$CMX340 format
OSome of the data is converted in this format so that it cannot be completely restored even when dumped data
is loaded again.
Event number:Deleted event numbers are packed and sent.
During receiving, event numbers are ignored, and up to 200 events are received in
sequence from the first event.
Reel number:All reel numbers are received as “0001.”
Editing mode:Assemble-edited data is converted into insert-edited data (V, A1, A2, A3, A4) and
output.
Effect type:Only cut-edited events are received.
Slow-motion editing:Only events with 0a
(STILL) speed data are received with slow-motion editing.
Split editing:All split-edited data is received as audio split-edited data (with the recorder serving as
the reference).

This unit is equipped with an auto head cleaning function which automatically reduces the
amount of dirt on the video heads.  However, in order to maximize the unit’s reliability, it is
recommended that the video heads be cleaned as and when appropriate.
For further details on  how to actually clean the heads, consult one of our service companies or
your dealer.
Condensation
Condensation forms according to the same principle by which droplets of water form on the
window panes of heated rooms.  It forms in the unit when the unit or tape is moved to a location
with a significant difference in temperature or humidity.  It also forms when the unit has been
moved:
Oto a very humid location filled with steam or a room immediately after it has been heated up.
Osuddenly from an air-conditioned environment to a place with high temperature and humidity
levels.
When moving the unit to these types of locations, do not turn on the power immediately but
leave the unit standing and wait for about 10 minutes.  If condensation has formed inside the
unit, an error message “d” lights up on the counter display, and the cassette tape is automatically
ejected.
Leave the power on, and wait until the error message is cleared.
Maintenance
Before proceeding with maintenance, set the power switch to the OFF position, and disconnect
the unit from the power outlet: always remember to take hold of the molded part of the power
plug when doing this.
Use a soft cloth to clean the cabinet.  In the case of stubborn dirt, dilute some kitchen detergent,
soak a cloth in the solution, wring it out well, and now use it for cleaning.  After wiping up the dirt,
remove any remaining moisture with a dry cloth.
Do not use paint thinners or benzine.
