11 – External control
The DA-98 can be controlled by other units, either
through the
REMOTE IN/SYNC IN
TASCAM con-
nector [43] as described in 9, “Synchronization
with other DTRS units”, the 9-pin
RS-422
serial
control connector [40], or through the
MIDI IN
con-
nector [41] using MIDI Machine Control.
11.0.1 Selecting the control source
(protocol)
1) Go to menu group 3, move the cursor to
(control protocol) and press
ENTER
:
2) Use the
UP
and
DOWN
keys to select between
, , and .
These are all self-explanatory, except for the
setting, which refers to the sync/control bus carried
through the
RS-422
connector [40]. An example
of a device which can use this protocol is the TAS-
CAM ES-61 editing controller.
11.1 Use with 9-pin external
control
The RS-422 control allows the DA-98 to be con-
trolled by a number of different editor/controllers,
in the same way as a VTR or DAT.
11.1.1 Video clocking
If the DA-98 is to be controlled by a video editor,
it is essential that the DA-98 and the controller
receive identical video signals from the same
source (a video generator, for example).
The DA-98 should also be set with video resolve
set to
, either free-running or rechase (see 10.6,
“Video resolution”).
The
CLOCK
switch of the DA-98 [30] should be
pressed until the
VIDEO
indicator lights.
11.1.2 Emulation
The DA-98 is able to emulate a number of differ-
ent units, so that when a Device-ID request is sent,
the appropriate reply can be sent back in response.
1) Go to menu group 6, move the cursor to
(Emulation Device) and press
ENTER
:
2) Use the UP and DOWN keys to select a device
from the following list:
•
•
•
•
•
•
•
•
3) Set your editor to control the device which is
closest to the emulation you have just selected.
If the editor determines its controlling method
from the reply to Device ID request, you should
try using IDs starting from the top of the list.
If the editor recognizes “TASCAM” (and there-
fore bypasses video emulation) use the
emulation setting.
11.1.3 Record delay
Most recorders (both VTRs and audio recorders)
drop into record a short time after they receive the
command to start recording, and editor/controllers
are programmed to take this into account.
However, the DA-98 starts recording immediately
it receives the command. You can compensate for
this using the Record Delay settings.
NOTE
The selection of an external control protocol does not
disable the local controls. When an external controller is
selected, the last control pressed, whether local or
remote, operates the DA-98.
