3.1.2.1 Considerations for rechargeable Batteries used in AOS products
Before conducting any tests where battery operation of the camera or
backup of the memory in case of power fail is required make sure that the
capacity of the battery is sufficient and the battery is charged. AOS
Te chno lo gies is un der no circumst anc es res po n sib le for an y loss of data
in case batte ries fa i l for whateve r reasons .
Batteries have a limited life time that heavily depends on the use of the
camera. The batteries are NOT covered by the AOS general warranty. AOS
warrants that at time of shipment the batteries have its nominal capacity.
Replacement of batteries by authorized and trained A OS personnel only.
Any kind of warranty is immediately void if batteries are replaced by non -
authorized personnel.
The batteries used in the AOS cameras are of NiMH type (Nickel metal
hydride).
When disposing the camera make sure to follow proper environmental
handling and guidelines.
3.1.3 Switching-on and -off procedure
1- Switching on (standard) when camera is switched off
•press “Power” push button shortly
•wait until startup sequence has been completed ( “System”
LED comes to a rest)
2- Switching off (standard) when camera is switched on
•press “Power” push button shortly
•“Power / Reset” LED will indicate the shutdown sequence
3.1.4 Reset to Factory Preset
When it is required to go back to factory presets (e.g. IP address unknown) the following
procedure applies
•press and hold “Power” push button for more than 4 sec
•once LED starts flashing release button and wait until startup sequence has been
completed
Note: The factory pre-set IP address is in the range of 10.0.0.115 to

3.1.5 Force camera shut-down
Sometimes, due to external events such as heavy EMI discharge on camera or DC voltage
electrical noise the camera “hangs up”. To abort any camera operation and enforce switch off
camera the following procedure applies:
•press “Power” push button for more than 4 sec
•Camera shuts down without the normal procedure. This is only necessary and
recommended if the camera does not react on the standard switching off procedure
(see par. 3) or is in a “freak” position (i.e. all LED’s b linking)
Note that in case you switch off any C-series camera it is imminent to have
the camera unpowered for min 30 sec. before switch on again. When
switching on the camera within 30 sec after power down some setting may
not be deleted due to camera internal power management reasons.
Note: When it is necessary to reset the camera, hold the reset button
pressed for a minimum of 1 sec. Otherwise faulty settings may be loaded.
3.1.6 Connecting the camera to a PC
Your AOS camera does not need a sp ecial or dedicated control device, often called “camera
controller” or similar. With its standard Gigabit Ethernet data interface, your camera can be
simply connected to any standard PC (Laptop or Desktop) or Ethernet -based LAN data
network.
Follow the following steps to connect the camera to your PC
-install the included camera control SW (AOS Imaging Studio V4)
-switch your camera on (see 3.1.3)

the camera back panel (see 5.1.3 for explanation)
Your high speed camera has been carefully adjusted for accurate back focus alignment to
make sure your lenses can be precisely focused all the way between close up and infinity.
However, if you use special (close up) optics or any non -standard lens, it might be necessary
to re-adjust the back focus by following these steps:
Adjusting the backfocus:
- loosen Allen screws to free focus ring on both
sides of the camera
- set lens to infinity and its iris to maximum
(lowest f-stop number, i.e. 1.4)
- aim at an object near the horizon (infinite
setting)
- adjust focus ring until distant object is in
focus
- set lens to 2m
- aim at an object in exactly 2m distance
(newspaper on a wall)
- adjust focus ring until object is in focus
- repeat steps until close and distant objects
can be focused correctly

6Operation 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.
6.1.1 Sleep mode
In the sleep mode the camera internally shuts down all tasks not required for data security,
communication and battery charging. Recording in the camera buffer are retained and may be
accessed again. Lowest power consumption assures data security in the RA M buffers for up to
30mins. By receiving a command the camera goes automatically into READY mode.
The duration of how long data are retained in RAM memory of the camera
is depending on the capacity of the built in battery. The battery assures 1
hour of data security under standard conditions. Battery time is affected
by temperature, age of battery and humidity that can result in a
substantial reduction of the time which data can be retained in the RAM.
6.1.2 Ready mode
In this mode the camera runs at full speed but having the sensor only active for preview
modes. In this mode the camera is being parameterized and setting of the scene is performed.
By clicking the green button the camera goes into the READY mode. If in t he option “Skip Set-
to-rec” is selected the camera goes directly into recording mode as selected. A message will
appear to acknowledge the overwriting of the buffer.

6.1.3 Pre-triggering mode
When a pre-trigger time is selected the camera may go from READY mod e into PRE-TRIGGERED
mode by either clicking on the white button icon on the screen or by using the external
connector to supply a PRE-TRIGGERING signal from an external source. Once in PRE-TRIGGERED
mode the amber and red light on the back of the camera s tart flashing.
When you put the camera into PRE -TRIGGERED mode via the PC, be sure
you have not disconnected the Ethernet link. The Ethernet link may be
disconnected after the camera is in PRE -TRIGGERED mode.
6.1.4 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 “Data” LED is constantly on. After accessing the camera
via Ethernet this LED goes out.

8Multi camera setups
The GigE data interface of the AOS high speed cameras, together with the AOS Imaging Studio
software, allows connecting and using more than one high speed camera to one control PC.
8.1.1 Multi camera systems without frame synchronization
If cameras have to, or can, be operated independently (without frame synchronization), the
cameras can simply be connected using their GigE data interface and CAT6 cables. To bridge
longer distances, commercially available GigE network components like Brid ges, Hubs and
Routers can be used.
The trigger signal has to be provided to each individual camera using 2-wire trigger cables and
/ or AOS trigger cables.
