7Operation Modes
AOS High Speed Camera basically has 5 operation modes that allow an efficient power
management. Understanding the functionality of the camera is essential for best operation of
the camera.
7.1.1 Pre-triggering mode
When a pre-trigger time is selected the camera goes from READY mode into PRE-TRIGGERED
mode by clicking on the green button icon on the screen . Once in PRE-TRIGGERED mode the
green and red light on the back of the camera start flashing.
When you put the camera into PRE -TRIGGERED mode via the PC, be sure
you have attached the Ethernet link. The Ethernet link may be
disconnected after the camera is in PRE-TRIGGERED mode.
7.1.2 Recording mode
In this mode the camera finishes the ongoing recording and then awaits access (reconnection
of the Ethernet link). The camera automatically goes into a power save mode after the
recording.
As long as unsaved data is in the camera (no access via Ethernet after a
recording) the red “Recording”LED is constantly on. After accessing the
camera via Ethernet this LED goes out.
Note: The trigger input of the L-/M-PRI is level sensitive. This means that
before a recording is started the input levels must be set as follows:
•Trigger level must be “high” when using “falling edge trigger”
•Trigger level must be “low” when using “rising edge trigger”

8System setup
Your AOS highspeed camera with its standard Gigabit Ethernet Data interface can be used in
many different configurations, depending on the application you have.
8.1.1 Scope of supply
Your AOS high speed camera is delivered with the follo wing:
-high speed camera
-2mm Allen Wrench
-Power / Trigger Adapter cable 0.5m
-Ethernet data cable
-power supply 110 -230VDC/24VDC
Add-Ons
Add-ons are extension modules especially designed for your AOS high speed camera to extend
the functionality of your camera for your specific applications.
8.1.2 Non-Volatile Memory (optional)
L-and M-PRI cameras offer optionally non-volatile memory in the camera.
The built in SSD offers a convenient way to store the image data directly in the camera. The
SSD may be accessed any time later by means of AOS Imaging Studio V4.
9Multi camera setups
The GigE data interface of the AOS high speed cameras, together wit h the AOS Imaging Studio
software, allows connecting and using more than one high speed camera to one control PC.
9.1.1 Multi camera systems without frame synchronization
Cameras may be operated independently with or without frame synchronization. AOS cameras
are simply be connected using their GigE data interface and CAT6 cables. To bridge longer
distances, commercially available Gig abit Ethernet network components like Bridges, Hubs and
Routers can be used.
Note: Make sure the additional network devices support jumbo frames.
The trigger signal has to be provided to each individual camera using 2-wire trigger cables and
/ or AOS trigger cables.

9.1.2 Frame Synchronization
For accurate motion analysis, cameras may be synchronized to make sure each frame starts at
the very same time to avoid time slip:
Time slip due to drift of individual non -synchronized cameras
Exact synchronization by phase lock of cameras
Make sure you put the M-PRI / L-PRI into sync mode or free run mode by
means of Imaging Studio V4 software. You must activate the external
synch mode in the camera to enable phase lock.
Make sure that the slave camera is capable of recording in the frequency
range set of the master camera. The slave camera may not function
properly if the range is too high or too low and may produce scrambled
sequences as a result.

9.1.3 Multi camera systems with frame synchronization (setting 1)
-the camera from which the Sync Out signal is used acts as the MASTER,
while the camera which receives the sync signal on its Sync IN line,
works as the SLAVE
-each camera can have a different setup (resolution, frame rate, trigger
setting etc.)
-the MASTER controls the frame rate of all following SLAVE cameras.
SLAVE cameras run on the same frame rate then the MASTER camera
Make sure that the SLAVE camera is capable of recording in the
frequency range set of the MASTER camera. By violating this condition
the SLAVE camera may not record in sync mode and/or produce
scrambled sequences.

9.1.4 Multi camera systems with frame synchronization (setting 2)
-The external clock can have any frequency, also uneven frame rates like
637Hz
-each camera can have a different frame rate setting. However, the actual
frame rate is given by the external clock
-Example:
External clock = 637 Hz
Setting cam 1 = 1’000fps / 512 lines -> runs actual on 637 fps / 512 lines
Setting cam 2 = 700 fps / 1024 lines -> runs actual on 637 fps / 1024 lines
Setting cam 3 = 1’000fps / 512 lines -> runs actual on 637 fps / 512 lines
Setting cam 4 = 1’000fps / 512 lines -> runs actual on 637 fps / 512 lines
-each camera can have a different setup (resolution, frame rate, trigger
setting etc.)
-the external sync source controls the frame rate of all cameras.
Make sure that all cameras are capable of recording in the frequency
range set by the external sync source. By violating this condition the
camera may not record in sync mode and/or produce scrambled
sequences.

10 Maintenance
The L-/M-PRI high-speed cameras are entirely electronic with no mechanical parts prone to
wear and tear. Maintenance is therefore reduced to the absolute minimum. However,
following these steps will not only extend your cameras lifetime, but will also offer a trouble-
free operation.
10.1.1 Lenses
The AOS cameras offer an industry standard C-Mount that will allow both C-Mount lenses and
a multitude of other lenses such as Nikon, Canon, PL with appropriate adapter. See your
distributor for details.
The camera sensor of the L - and M-PRI is larger than 1”. AOS recomm ends use
of 4/3” lenses such as the KOWA LM__XC series
10.1.2 Cleaning the AOS High Speed Camera Infrared filter
Your AOS High Speed Camera (color versions standard) does have an optical filter to block
infrared light from entering the camera in the optical path. Dust and dirt on this filter may be
best removed by using either a non-oil based dust-off air spray or some optical cleaning
tissues. Sticky dirt and fingerpr ints may be removed using isopropyl alcohol.
Removing particles (e.g. sand) by improper devices may result in scratches
on your filter. Such scratches do influence the overall image quality.
Infrared light is a part of the visible light and not bl ocking it may result in
false color in the actual image. However, for applications where light is
critical (e.g. bore scopes) one may remove the IR filter. This is especially
true when using a monochrome version of the camera.
11 Troubleshooting
Despite all quality procedures in design, development and production there can be errors in
the software. Any known issues are listed in the release notes of the specific software release.
