2. FEATURES
“83-pin and @-pin remote control connectors
These two types of remote connectors allow the unit
to be used with various types of VTRs: Betamax,
“BETACAM” and U-matic VTRs, and even a 1-inch
helical scan VTR as follows:
Type of a VIR
Betamax VTR
SLO-383/420 *
BVW-10*, -40, -75 series .
BVU-800, -900 series,
VO-5800 * /5850
BVH-2000, -3000 series
TLitime code/ATC (relative time code) sélection —
When a VTR is connected through the 9-pin remote
contro! connector, you can select a CTL signal, time
code or RTC (relative time code) for editing. When
RTC is selected, the time code is used as an edit
reference and its progress is counted as CTL on the
time counter. RTC can be used to determine how far
the desired tape point is from the IN point as it can
be reset in the same manner as a CTL.
ime learning capability
The unit can detect the pinch on delay time of the
connected VTR and hold this data for a week even
after the power is turned off. Therefore, the operation
with the connected VTRs is very smooth and no
discontinuity of the picture is produced by this unit.
You can connect not only the VTRs which have the
same remote connectors but also VTRs having a 9-pin
remote connector and those having a 33-pin remote
connector to the unit, and control them remotely.
In the assemble mode, the video signal and audio
signals (A1 and A2) are edited together at the same
time.
In the insert edit mode, they can be edited separately.
The unit can also perform the split edit. Therefore,
you can set the audio IN point independently from
that of the video channel and vice versa.
Materials you are to edit can be previewed and those
that you have edited already can be reviewed.
* The BVW-10 is a player, and other VTRs cannot be used as a
recorder when connected to this unit.
You can easily preset various data, such as the preroll
time and the edit timing, needed for editing on the
front panel.
Variable speed of playback functions in the shuttle
mode and jog mode enable you to locate the. edit
point more quickly.
‘Synchronize
The REF.VIDEO IN connector allows the unit to
synchronize with the connected VTR. Therefore, the
unit can perform absolutely precise editing.
When the VTR which has the dynamic tracking
function is connected to this unit as the player VTR,
this unit can edit the picture in the variable speed.
AIR SPSS et Te SIERO
The unit indicates the error by displaying the error
number on the time counter and outputting a warning
sound. You can understand right away what kind of
error has occurred and what you should do.
itable
The unit can be mounted on the RMM-450 rack mount
metal which is designed for a standard 19-inch rack,
and on the SU-500 series system console by using the
SU-450 double size table.

1-5. Address bus check
Power ON after S201 OFF
Turn OFF the 8-bit DIP switch S201 on the CPU board
through it is usually set to ON position. The CPU
then executes NOP (00) since the data bus on the
CPU board is isolated from devices other than CPU
and pulled down by a resistor. At this time, the
address line shows simple increments, (However, a
refreshed address is assigned to A7 to Al5,) .
Observation of a waveform on the address line with
an oscilloscope makes fault identification easier.
