i--SPEED LT, i--SPEED 2
Chapter 1 Introduction
The Olympus i-- SPEED LT, i-- SPEED 2 are self--contained high speed
video cameras. This means that it contains all the functionality required to
obtain high speed video and does not require the presence of a PC,
although PC connection is possible if required. The camera has been
designed to be used in two ways as follows:
Controller Display Unit
The Controller Display Unit (CDU) is available as an optional
accessory for the Olympus i-- SPEED 2
. This product displays the
image from the camera in real--time and permits the most flexible
use of the camera, by using a series of buttons around the outside
of the screen. The bottom seven buttons are used as “soft keys”,
that is, the function of each button is dependent on the text written
above it on the screen. The four buttons on the right hand side
have dedicated functions and these are Text, Back, Up and Down.
The menu system has been specially constructed to take maximum
advantage of this layout. CDU operation of the camera is
described in detail in Chapter 6
of this manual.
PC/Laptop Connection
The Olympus i-- SPEED 2 may be connected to a PC or laptop via
the Ethernet connector and an appropriate Ethernet network. In
this case, the unit is controlled from the PC / laptop and the image
is visible on the PC screen. This requires the PC to be running the
basic control program which is supplied on a CD ROM with the
camera. Upgrade options are available for the s upplied software
and these provide additional functionality. Details of the upgrades
are available from Olympus representatives, see Chapter 10
Spares and Accessories. In Ethernet mode, all the functions of the
camera are available, but they are presented and controlled by the
PC software.
For details of the operation of this software, reference should be
made to the documentation supplied with the software. Information
regarding the c amera, however, is contained in the Reference
sections of this manual.

i--SPEED LT, i--SPEED 2
1. Power Connector
The rear panel Power connector is used to take power into the
camera, nominally 12V DC. This power is used to operate the
camera, but is also used to operate the CDU. The power input
is protected against reverse polarity connection and this will
normally result in a blown fuse.
2. Power LED
The power LED will illuminate when 12V is applied and the fuse
is operating correctly.
3. Fuse
The fuse is replaceable by the user and is accessed by
unscrewing the fuse holder. Care must be taken to replace the
fuse with one of the correct size, type and rating.
4. Composite Video BNC Connector
This connector provides an industry standard PAL or NTSC
composite colour video to a video monitor unit. BNC is an
industry standard connection for this type of signal, and a BNC
composite video cable is provided. The video available from the
connector may be switched between NTSC and PAL via the
menu system in the CDU.
Composite video signals are designed to be driven into a
terminated connector, so care must be taken to ensure that the
last piece of equipment in the BNC cable chain is set to
terminatewith75Ohms.
5. Controller Connector
This connector is used to connect the CDU to the camera. It
carries power from the camera to the CDU, video from the
camera to the CDU and receives button press information from
the CDU.
Although this connector conforms to the LVDS industry
standard, it is recommended that only cables supplied by
Olympus are used and it is imperative that no equipment other
than the CDU is attached to this connector.
Nomenclature & Functions
11
i--SPEED LT, i--SPEED 2
6. Ethernet Connector
This connector is a standard RJ45 connector with two integral
LEDs. The signal standard is the Ethernet 10--T or Ethernet
100-- T and the Olympus i -- SPEED LT, i-- SPEED 2 will
automatically switch as appropriate. The Ethernet cable must
be connected to an Ethernet switch, although direct connection
to a PC / laptop is possible if the crossover cable is used. It is
strongly recommended that all the components in the Ethernet
network are compatible with 100--T as this will enable the
camera’s network controller to operate at this higher speed.
7. SVGA Connector
This connector provides a SVGA s ignal which contains the
video image and overlay graphics. When the CDU is being
used, this signal is a copy of the CDU image. The output
standard is the 60Hz SVGA PC video signal and the connector
conforms to the PC video 15 pin D --sub standard. As a result,
this signal may be fed directly to a PC monitor, (CRT or LCD)
and provides the best quality live analogue video signal
available from the camera.
8. Compact Flash Slot
The camera is able to operate with type I and II compact flash
memory card. Once the card is inserted it must be pressed
firmly in place and may be ejected by pressing the button at the
top of the slot. It is not necessary to switch power on and off as
the card is inserted and removed, but care must be taken not to
remove the card while writing, deleting or formatting is in
progress.
9. Feature Connector / Feature Connector Cable
This connector contains a number of signals. They are gathered
together in one connector to reduce the size of the camera’s
back panel and thereby permit the manufacture of the smallest
possible unit. In order to gain access to the signals in this
connector, a feature connector cable is supplied and this
terminates in a series of connectors, labelled as follows:
Nomenclature & Functions
12
i--SPEED LT, i--SPEED 2
Feature connector cable
Trigger Input / Trigger Switch: This connector (and the
supplied trigger switch if required) are used to trigger the camera
while recording is in progress. Further details are provided in
Chapter 8 “Understanding the Olympus
i--SPEED 2”.
When the trigger is set to 0%, the trigger counter is set to the
length of the memory, so that the trigger point appears at the
beginning (0%) of the final video clip. A setting of 100% will
cause the recording to stop immediately, placing the trigger
event at the end of the video clip.
The signal is TTL level and the user may select rising edge or
falling edge trigger options.
The trigger input contains a “pull-- up” resistor to enable the
supplied trigger switch to be used without further electronics. It
should be noted that the trigger switch provides a falling edge.
In practice, the trigger switch also produces a rising edge
because of switch bounce, but this cannot be guaranteed.
Nomenclature & Functions
13
i--SPEED LT, i--SPEED 2
Trigger Output: This output is TTL compatible and gives a 1
microsecond wide active high pulse. The rising edge signifies
the start of the first integration period of the sensor to occur after
recording has stopped. This connector may be used to cause
another camera to trigger after the end of this camera’s
recording. In this way a series of cameras may work in a
daisychain.
When daisy chain operation is used, the first cameras trigger
point may be selected by the user, but it is recommended that
the second camera’s trigger position is set to 0%.

i--SPEED LT, i--SPEED 2
Sync Input: The camera’s frame rate may be determined by an
external signal source, typically another camera. In this case,
the camera would not only lock its frame rate to that of the other
camera, but the exact moment at which each frame is captured
would also be locked to the other camera (+/-- 25ns). In this
way, it is possible to have multiple cameras viewing one event
and taking images simultaneously. The input is TTL compatible
and requires an active high pulse, in which the rising edge
signifies the start of the integration period.
The camera constantly monitors this input and will notify the
user when an incoming sync is detected. When this occurs, the
camera will measure the speed of the incoming signal and offer
the user the opportunity of automatically configuring for
synchronised operation.

i--SPEED 2
cameras as mentioned above.
Analogue Input 1 and 2: As well as recording video, the
Olympus i -- SPEED LT, i -- SPEED 2 is able to record two
analogue signals. These are digitised to 8 bits and saved in the
internal memory buffer along with the video. The signals may be
displayed on the CDU or PC screen as required. The signals
are sampled at a speed related to the frame rate and this may
be set from a menu. The sample rate is variable from 1 sample
per frame to 100 per frame, subject to a maximum of 100,000
samples per second.

10. Cooling Holes
The rear panel has a number of cooling holes, and more are
located on the sides of the casework at the front of the unit. The
outer holes on the rear panel and the holes at the front of the
unit are air inlets and the holes in a circular pattern on the rear
are air outlets. The primary reason for including forced air
cooling has been to eliminate localised hot spots within the
electronics and care should be taken to ensure that the cooling
holes are kept clear at all times as described in Chapter
9
“Maintenance”
.
11. Soft Reset
This button will allow access to the data recovery menu if the
i-- SPEED LT, i -- SPEED 2 camera stops responding after being
triggered.
Nomenclature & Functions
17
i--SPEED LT, i--SPEED 2
12. Back Focus Control
It is sometimes necessary to adjust the distance between the
C--mount face and the image sensor to accommodate lenses
from different manufacturers and lenses with different optical
tolerances. The Olympus i -- SPEED LT, i -- SPEED 2 has a back
focus assembly located in the front of the unit to permit this
adjustment.
To adjust the back focus, screw a C--mount lens into the
C--mount in the normal way. Turn the locking ring anticlockwise
(when viewed from the front) to unlock the C--mount thread ring
then rotate the lens to adjust the back focus as required -- a
series of ‘click’ positions will be felt. When complete, the
adjustment should be left in one of these ‘click’ positions and the
locking ring rotated clockwise to lock the C-- mount thread ring in
position.
C--mount lens
Locking ring
As a guide, the correct setting of back focus is obtained by
pointing the camera at an object a known distance from the lens,
preferably an “infinite” distance. The scale on the lens is then
used to set the focus ring to this distance. The back focus is
then adjusted to obtain the best image.
13. Mounting Holes
The base of the unit is fitted with 5 standard ¼” UNC mounting
holes. It is recommended that the central hole is used for
mounting the camera (e.g. to a tripod) and the other holes may
then be used to mount light--weight accessories to the camera.
It is important that the i-- SPEED 2 HG camera is mounted using
the four outer mounting holes when used in high--G applications.

14. Protective Bar
The back of the unit is fitted with a protective bar. The purpose
of this is to protect the connectors from damage if the unit is
placed on a shelf and pushed back against a wall. In spite of
this, the bar may also be used as a handle to carry the camera
or to support light--weight items when the c amera is mounted on
a tripod.
15. Protective Glass
The image sensor is located at the front of the camera inside the
C--mount aperture. A protective glass is fitted to this aperture to
shield the sensor from dust and damage. It is recommended
that the glass is kept clean as detailed in Chapter
9
“Maintenance”
.
16. Battery Memory
The Olympus i-- SPEED LT, i-- SPEED 2 contains a battery
powered clock and memory. This is used to keep track of the
time and date while the camera is switched off. The memory is
also used to store some of the user controls, such as the TCP/IP
address, the camera’s ID, the TV monitor standard and the
language setting. The battery is a non--replaceable lithium cell
which should last for approximately 10 years. In the event of
battery failure, default values will be used at each switch--on.

1. CDU
The CDU displays the image from the camera in realtime and
permits the most flexible use of the camera, by using a series of
buttons around the outside of the screen. The CDU is connected
to the camera’s Controller connector via a 3m controller c able (a
10m cable is available as an optional accessory). The CDU
takes power and video from the camera and requires no
batteries or further connections.
The camera is able to recognise the presence of the CDU and
operates a specialised menu system. When changing from
CDU and viceversa, the power should be switched OFF and ON
again.
LCD Panel, Viewing Angle: At the time of design and writing
this manual, the LCD panel used in the CDU is the best
available LCD panel of this size and resolution. Even this
market leading panel, however, has a restricted viewing angle in
the vertical direction and the user is advised to experiment with
the CDU to find the optimum angle at which to view the image.
Protective Screen: Although the CDU LCD screen is protected
by a tough plastic sheet, it is still recommended that care is
exercised when handling this unit. It is also important to keep
this screen clean to preserve its anti--glare properties and this is
detailed in Chapter 9 “Maintenance”
.
2. Soft keys
The bottom seven buttons on the CDU are used as “soft keys”,
that is the function of each button is dependent on the text
written above to it on the screen.
3. Function keys
The four buttons on the right hand side of the CDU are
dedicated function buttons, these are Text, Back, Up and Down.
The menu system has been specially constructed to take
maximum advantage of this layout.
4. Stand
The CDU is equipped with a stand which may be set to a
number of ‘click--stop’ positions to allow standing on a flat
surface at various angles or hanging from a convenient hook.
The stand may also be folded flat for storage or when the strap

Chapter 5 Getting Started
This section provides a functional description followed by the basic steps
required to start using the i-- SPEED LT, i-- SPEED 2 camera system.
5.1 Functional Description
Assuming the system has been connected as described in Chapter 4,the
typical sequence of events is as follows:
The frame speed and shutter settings are c hosen, the lighting and lens are
adjusted appropriately and the camera is placed in record mode.
The camera then takes video at high frame rates and stores it in the
built--in memory. This memory is configured in a circle so that, once the
memory is full, each new frame replaces the oldest stored frame. In this
way, the camera keeps a rolling history of the scene it views and this
process can continue indefinitely. Once the desired event has occurred,
the camera is stopped or triggered.
During the entire set--up and record process, the CDU and any monitor
attached will display the live image in full colour and in real time.
Once the required video clip is stored in memory, it may be viewed by
using the player function. In this mode, video may be played forwards or
backwards at a range of speeds. A convenient bookmark system is
provided (CDU only) for easy navigation between sections of interest.
The memory in the camera will be erased without power, so if it is
necessary to preserve the captured video after power off, it may be
recorded onto a compact flash memory card, which is inserted into the
card slot provided. The internal memory is much bigger than any card
currently available, so only a subsection of video may be stored. High
speed video clips generally contain a large amount of “dead time” and a
relatively small amount of useful motion, in recognition of this, the Olympus
i-- SPEED LT, i -- SPEED 2 has a clip select function which allows a precise
choice of the video to be saved.
Further to these functions, it is sometimes necessary to measure a feature
of the recorded motion and the Olympus i-- SPEED 2 contains an
advanced measurement suite.

5.2 Use with the CDU
This section describes the basic steps required to start using the
i-- SPEED LT, i -- SPEED 2 camera system with the CDU. Additional
information regarding functionality of the CDU can be found in Chapter 6
.
1. Connect the system as described in Chapter 4, then connect the
mains power cable to a suitable AC wall outlet and switch the
power ON -- the i-- SPEED 2 splash screen is displayed on the CDU.
NOTE
When using the i-- SPEED 2 HG, the lens must be
completely covered (eg with a lens cap) from power on
until the splash screen appears.
2. Press any key, a live video image is displayed on the CDU. Adjust
the lens focus and iris as required to achieve a sharp, bright image.

3. Depress the Quick button to enter the Quick menu
4. Depress the Speed and Shutter buttons to select the desired frame
speed (def: 60fps) and shutter speed (def: x1). You may need to
re--adjust the lens focus and iris to achieve a sharp, bright image.
5. Depress the Record button, a camera icon is displayed and the
camera records video into its circular buffer until the Stop button is
depressed or the trigger button is pressed.
NOTE
If the trigger is used, recording will stop after a delay.
This delay depends on memory size, the trigger position
setting and frame speed.

NOTE
When using the i-- SPEED 2 HG for high--G tests,
disconnect the CDU from the camera. When recording
has stopped, reconnect the CDU.
When recording has stopped, whether by trigger or STOP button,
the camera will present the Playback Menu. Press the Player
button to enter Player menu and display the first recorded image in
the memory.
