3. General Product Information

The LOCPRO 35 is a lightweight mobile projector for on­location use. A switch-over mirror system allows either wall
projection or the use of a 1/3” CCD Color High Resolution
video camera. The LOCPRO 35 can synchronize DAT-re­corders or perfotape players for picture/sound synchronization.
The following sync signals are available for output: For
synchronization with DAT recorders a timecode LTC signal,
for synchronization with perfotape players in connection
with ASU-accessory (Audio Sync Unit) a biphase signal
with a programmable number of pulses per picture.

•

Fast film transport and simple operation:

The film is transported by a motor with a directly-driven
double-sided sprocket wheel. This patented intermittent
film drive system is acute to less than 0.01 seconds at
any projection speed. Constant film tension and safe
film transport are ensured by computer-controlled drive
motors for both film carriers. The ”auto-stop” feature
stops the film automatically 6 ft (2 m) before the end
of the film.

Automatic detection of the winding direction makes it
unnecessary to manually switch over from winding
direction A to B.
The open film channel facilitates film loading once the
film has been placed onto the winding plate. All steps
from the formation of loop sizes to standby operation
are carried out fully automatically. In addition, a film
can be removed at any time even in the middle of a
film roll.

•

Direct high speed rewinding:

High speed rewinding and quick location of certain film
scenes is easily possible with the gentle high speed
shuttle/rewinding system. By simply turning the Master
Control Knob this system allows you to switch directly to
high speed winding at 200 fps and back to the chosen
projection speed. The frame counter remains active so
that after switching back from high speed winding to
projection speed, the frame line is automatically
repositioned to the correct setting.

Excellent image quality with flicker-free projection:

Best possible image brightness, excellent picture steadi­ness and image quality are the outstanding features of
the LOCPRO 35. The 400 W HTI lamp allows optimum
projection of more than 6 ft (2 m) image width and an
average color temperature of 5.400°K.

The built-in video camera (optional) can be connected
to a monitor, video recorder or video printer. Two video
outputs are available, FBAS (BNC) and Y/C. In addition,
it is possible to mask the video image electronically to
match the different film formats as required.

•

Telecine Mode (Pulldown Mode):

Flicker-free transfer onto video tape at 24, 25 or 30 fps
is possible depending on the integrated video system ­50 Hz PAL or 60 Hz NTSC. In both cases, the integrated
video camera synchronizes frame transport.

•

Sound Synchronization:

To synchronize DAT-players an LTC signal (timecode)
output is available. In connection with an ASU, a
biphase signal (synchronized picture change signal with
forward/reverse recognition) allows for synchronization
of perfotape players. For the adaption to different
perfotape players it is possible to program on the ASU

6.9 Interfaces

Note: All interface cables used must comply with CE

and EMV guide lines.

X1X2X3

6.9.1 Serial Interface (X1)

Plug type: Sub-D 25 pin socket
Via serial interface (X1) ➪ photo the operational status of the

LOCPRO 35 can be checked and changed from a computer.

Chapter 8 ”Serial Interfaces X1” contains listings of
technical data as well as listings of computer commands.

Plug – Pin configuration: See Annex ”Interfaces”

6.9.2 Ext Synchro (X2)

Plug type: Sub-D 15 pin socket
Via this interface ➪ photo a signal for shutter synchroni-

zation can be supplied externally and the internal shutter
signal accessed.

Functions

Cine Mode: ........................................................ 48 Hz

Normal and Telecine Mode: ....................... 50 or 60 Hz

Shutter revolutions can be changed by ± 3%.

Input: .................... 5 V TTL potential-free on optocoupler

Output: ................. 4 V potential output or potential-free

Plug Pin configuration: see annex ”Interface”

Note for shutter synchronization:
Signal source:
External = control frequency via X2; top priority!
Video = when video ”on”. Quartz of video camera.
Internal = internal quartz generator.

6.9.3 Timecode (LTC) and Biphase A/B
(X3)

Timecode:

For sound synchronization of a DAT tape player with the
LOCPRO 35, e.g. during transfer of film and sound onto
video tape, a timecode signal is supplied on interface X3

Functions

➪ photo (see page 39).

The timecode signal (80 Bit per picture) is only supplied in
the forward running mode (to the right) with frame rates
of 24 fps, 25 fps or 30 fps. The read-out timecode frame
numbers correspond to those of the frame counter on the
display. A frame counter reset on the LOCPRO 35 therefore
also resets the timecode to zero.

The projection frame rate of the LOCPRO 35 has to be
matched to the DAT speed. This is possible via ”Mode”
Key (see chapter 6.4.2).

If the LOCPRO 35 is synchronized externally, ensure
accurate synchronization frequency within ± 1%.

1) Run the LOCPRO 35 and DAT tape player separately

to the sync point (starting position of transfer with
appropriate leader).

2) Connect the DAT tape player via interface cable (9 pin
Sub-D on XLP plug) with socket X3.

3) Reset frame counter to zero (”Reset” Key).
If necessary, set the timecode value supplied at the
sync point of the DAT recorder to offset so that the the
time code value ”0” emanating from the LOCPRO 35
corresponds to the value expected at the DAT recorder.

Start the transfer with the Master Control Knob.

Biphase:

Biphase operation is only possible with the Audio Sync
Unit (ASU).

To synchronize with external units, a sync pulse (1 pulse per
picture) is supplied on interface plug X3. When connected
to a programmable ASU, a biphase signal is generated
from this sync pulse.
(biphase A/B = moving direction recognition).

Plug type: 9-pin Sub-D socket.

7. Service and Maintenance

To preserve optimum projection and image quality, it is
essential to check the brightness and image quality every
six months and, if necessary, during such a maintenance
service the LOCPRO 35 should be adjusted to meet
factory quality standards.(see ”Service Manual”).

Make sure that the LOCPRO 35 is switched off
and completely disconnected from the mains
before starting service or maintenance work.
Unplug all interface connections.
