Section 5.1 - Transport controls
5-1
5 – Basic DTRS operations
This section covers the basic operations of con-
trolling the DTRS units connected to the RC-898.
For details of how to make parameter settings, etc.
and timecode operations, see 4, “Menu and basic
operations”, 7, “Making settings on the DTRS
units” and 10, “Menu and parameter reference”.
5.1 Transport controls
The transport controls on the RC-898 replicate
those on the DTRS units.
The logic of the transport controls is such that any
mode can be entered from any other mode. There
is no need to go through
STOP
.
5.1.1 Selecting the unit to which
operations refer
Generally speaking, the unit controlled by the
transport keys will be the first unit in the chain
(the other units in the chain are assumed to be
using the ABS chase protocol through DTRS
synchronization.
However, transport operations, etc. can also be
performed on individually-selected machines
other than the first one:
1) Press the
MACHINE
key [31].
The word
MACHINE
will start to flash in the
LOCATE TIME/VALUE
display [15].
2) Use the numeric keypad to enter the
number(one digit only) of the machine that you
want to control .
This number will be shown in the
LOCATE TIME/
VALUE
display [15], and the appropriate
MACHINE
number indicator[8] will light.
If you enter a machine number of 0, this is equiva-
lent to setting all DTRS units except the first into
slave mode, to follow the first unit.
Machine 7 is equivalent to a unit attached to the
parallel port [42], and machine 8 is equivalent to a
unit attached to the serial port [43].
5.1.2 Formatting tapes
The Hi8 tapes used in DTRS units must be for-
matted. This can be done either from the DTRS
units themselves, or from the RC-898.
1) Insert a new tapeor tapes into the DTRS unit
or units. Make sure that it is rewound to the
beginning of the tape.
2) From menu group 9, move the cursor to
Format, and press
SELECT
:
3) In this menu, as well as using the
NEXT
(
SHIFT
+
UP
) and
PREVIOUS
(
SHIFT
+
DOWN
) keys
to select an individual unit, all DTRS units
connected to the RC-898 can be selected to
format tapes together.
4) Move the cursor to the sampling frequency
field, and use the
UP
and
DOWN
keys to choose
between
44.1 and 48 (kHz).
5) Move the cursor to the “control” field and use
the
UP
key to change the setting from
off to
ready
6) Press the
UP
key again to change
ready to
on.
The
FORMAT
indicator on each selected DTRS
unit will light.
The three values for this parameter prevent acci-
dental formatting of a tape.
7) Press and hold the
RECORD
key and press the
PLAY
key.
The tape will start to be formatted.
It is possible to record audio and format a tape at
the same time. This is done by arming the tracks
before step 5 above. However, if you do this, you
should not interrupt the formatting process half-
way through a tape. Once you start formatting a

Do not use a tape which has previously been used for
recording video.

NOTE
If a digital signal is received at the
DIGITAL IN
connector
of the DTRS unit, and digital input has been selected (see
7.2.9, “Input selection”), the sampling frequency is decided
by the frequency of the incoming signal and cannot be
changed.
