9-4
function allows toggling the serial unit recording
capability.
1) From menu group 7, move the cursor to
9pinRecAc (9-pin recording acceptable)
and press SELECT :
2) Use the UP and DOWN keys to choose between
on and off .
When this parameter is set to on, the REC
FUNCTION keys which usually control tracks 41
through 48 (DTRS 6) will now control the E2
device logical analog and digital tracks (no matter
what the tracks actually are) as marked.
The following chart explains the relationship
between the serial unit, the split/normal mode, and
this function:
9.4 Other DTRS control
functions
The following functions described DTRS fea-
tures which relate to control, but are not timecode-
related. The RC-898 can only perform these func-
tions on DA-98 units. Some of these functions are
available on DA-88 units, but they cannot be con-
trolled from the RC-898.
9.4.1 Choosing a control protocol
The DA-98 can be controlled from a variety of
external sources as well as the RC-898. These
sources are: P2 protocol (9 pin), MIDI Machine
Control, and a bus protocol carried over the RS-
422 cable and produced by, for example, the TAS-
CAM ES-61 editing controller. See section 11.0.1
of the DA-98 manual for further details relating to
this function.
1) From menu group 3, move the cursor to Ctrl
Prt (control protocol) and press SELECT :
2) Use the UP and DOWN keys to select between
9Pin , MIDI , Bus and off .
Even when a control protocol is selected, the RC-
898 and DTRS sync protocol can still be used to
address and control the DA-98.
9.4.2 Track mapping functions
When the track arming and recording of a
DA-98 unit is controlled by an external controller,
you can specify which tracks on the DA-98 corre-
spond to the tracks controlled by the controller
(for arming and recording purposes). The standard
video controller protocol (P2 protocol) allows for
control of up to eight digital and four analog audio
tracks. This function allows you to map DA-98
tracks to the “logical” tracks.
This mapping of DA-98 tracks to controller tracks
does not imply any correspondence between the
user interface of the controller and the DA-98
tracks. It refers, rather, to the relationship between
the command signals transmitted by the controller
and the DA-98 tracks.
1) From menu group 6, move the cursor to Trk
Map and press SELECT :
2) Use the UP and DOWN keys to select the track
mapping, according to pre-set options as shown
in the table below.
Note that while there are no user-settable track
mappings, the pre-set mappings are designed to
cover every set of circumstances.
