3 The EXO series
The EXO series is a series of machine vision cameras for the low and mid-range
resolutions up to 20 MP. The EXO is available with different industry standard
interfaces such as GigE Vision, Camera Link and USB3 Vision.
The EXO is easy to integrate and comes with a full package of useful hardware
features.
The EXO-Series comes in a new 50 x 50 mm aluminum body. The elaborate, high
precision machined unibody housing ensures perfect temperature distribution
even for the most demanding sensors. A massive lens mount is designed to keep
any kind of lens in its proper position.The electric circuitry of the EXO is optimized
for low power dissipation, helped by the excellent temperature performance of the
housing. The EXO features the latest global shutter CMOS and CCD sensors
from SONY, CMOSIS and ON Semi.
A uniform form factor and identical standard interface connectors with identical
pinout facilitate camer model interchangeability, allowing system integrators to
adapt applications with varying conditions and requirements very quickly with min-
imum design effort.
3.1
USB3 Vision
USB 3.0, the extensively revised, third Universal Serial Bus (USB) version has
been renamed USB 3.1 Gen 1 by the USB-IF (USB Implementers Forum).
However, the technical specifications remained unchanged. USB 3.1 Gen 1
(USB 3.0) offers the same user-friendly plug-and-play technology as previous
USB generations, but with 10 times the performance and better power man-
agement. Nothing changes for users; they plug USB 3.1 (SuperSpeed USB) into
PCs and notebooks just like USB 2.0 (Hi-Speed USB) device ports.
The performance increase is based on USB 3.1 technology, which allows multiple
data streams to be transferred simultaneously - with a maximum 5 Gbps signal
bandwidth, compared to 480 Mbps with USB 2.0. Although the specifications are
5 Gbps, transfer rates may vary depending on the controller, cable quality and –
length as well on controller configuration.
USB3 Vision is one of the most flexible and scalable camera protocols for the
industrial market segment. The USB3 Vision interface is easy to integrate in your
system, with a data rate up to effective 350 MB/sec. USB3 powers the camera
via the interface cable and reduces cable complexity.
lUp to 620 MB/sec brutto transfer rate
lLeverages existing infrastructure for cables and connectors
lGenICam compliant
lCost effective / easy implementation and interfacing
In theory, USB3.1 Gen 1 can transfer rate is 5 Gbps, USB3.1Gen 2 even can
transfer 10 Gbps.
Despite being standardized, we find a significant amount of USB3 hardware being
sold still not capable to cope with these high data rates. This refers to some
3 The EXO series 8

USB3 host chipsets and USB3 hubs as well to high processing load in the host
computer. An integrated hardware buffer in the SVS-Vistek camera (240 MB in
size) will try to catch and buffer these cases. Burst Mode frame rate is limited to
maximum USB speed. The SVCapture GUI will show the real data rate of suc-
cessful transfers. If you encounter image losses, it might be worthwhile to run the
same camera task with different USB chipsets and / or processor.
Generally,
lUse a dedicated USB3 port at your computer
lDo not use USB3 hubs for your image USB stream
lConnect only the camera to this USB3 port
lIn case of image drops, try different hardware or reduce frame rate
lIf the client hardware (processing load) is too slow, the above is valid as well.
3.2 4I/O adds light and functionality
Fig.: 3-1: Illustration of 4I/O concept of switching LEDs
Your SVS-Vistek camera is equipped with the innovative 4I/O-interface allowing
full light control, replacing external strobe controllers. Each of the outputs can be
individually configured and managed using pulse width modulation. With its high
current output, the camera is able to drive LED lights directly without external light
controller.
The integrated sequencer allows multiple exposures with settings to be pro-
grammed, creating new and cost effective options. Logical functions like AND /
OR are supported.
lUp to 4 x open drain high power OUT
lUp to 4 x high voltage IN – TTL up to 25 Volts
lPower MOSFET transistors
lPWM strobe control
lSequencer for various configurations
lPLC fuctionality with AND, OR and timers
lSafe Trigger (debouncer, prescaler, high low trigger)
INFO Find an example how to operate light control in the section on sequencer
("Sequencer" on page 86).

3.3 Lens control
Various SVCam models are supporting adjustable lenses. Focus and iris of the
lens can be controlled from within the camera GenICam tree. A special Y-cable
might be required, contact [e-mail].
The following variable lens types are currently supported:
lMFT lenses (in Tracer series) have full support of lens focus, iris and zoom.
Only available in Tracer models no options selectable in GenICam tree.
lBirger mount
Ask [e-mail] for information of usability and restrictions of the
Birger adapter.
lVarioptic liquid lens
Control of extremely fast focus cycles. Make sure sensor diameter is
covered by lens.
lCanon EF lens
Focus and iris control is supported. Use high quality Canon lenses with
machine vision applications. The SVCam-EF adapter can be acquired from
SVS-Vistek.
INFO Lens control (except MFT) will make use of the serial ports of the Hirose con-
nector.
3.3.1 The Tracer adds dynamic lens control
INFO This section applies to the Tracer models (with “TR” in its type name like the
EXO304MGETR)
The increasing usage of machine vision in various branches such as agriculture or
packaging and tracking puts new challenges to the manufacturers of machine vis-
ion applications. Very often varying distances and difficult light conditions make it
a hard job to integrate machine vision into an industrial work flow. SVS-Vistek
pioneered the use of variable focus lenses into machine vision.
Tracer with Micro Four Thirds mount
The Tracer accepts this new challenge with a full blown dynamic lens func-
tionality. Equipped with the well known MFT (Micro Four Thirds) bayonet, the
Tracer supports
lAdjustable focus
lAdjustable zoom
lAdjustable aperture
With this feature set, the Tracer is able to focus extremely fast on various dis-
tances and can do closeups without loss of resolution. With zoom being relatively
3 The EXO series 10

slow, aperture and focus adjustment in most cases is done within 10-20 ms
(depending on the lens).
All of theses functions can be accessed in the application by the camera pro-
gramming interface or via GenICam properties. This makes integration of
dynamic lens control into third party software possible with no effort. Power sup-
ply and data control for the lens are done through the MFT bayonet, so no external
cables are visible.
The MFT lenses are optically optimized for sensors up to 1.3”, perfectly suited for
machine vision sensors. The optical construction defined by the MicroFourThirds
consortium, telecentric on the sensor side, provides smooth images and very low
shading. Mechanically built on magnetic rails in most cases, the stability and
repeatability of the lenses is surprisingly high. A wide selection of suitable lenses
for any application is available. As a surplus, MFT lenses provide excellent
optical performance regarding their price tag.
MFT lenses should have a small dot on the case, indicating the position to attach
it to the camera (find the matching dot on the camera mount). Turning the lens
clockwise until the lens stops with fixing click will attach it to the camera and put
the contacts in proper positions. For removing the lens, press the unlock button
on the lens and turn the lens counter-clockwise.
3.3.2 Use liquid lens on C-mount
We are supporting Varioptic liquid lenses. The liquid lens support does variable
focus only, zoom and aperture control are not existing with the Varioptic liquid
lens. You need a special serial cable with Hirose for connecting the lens to the
camera, please ask your dealer. Being extremely fast and robust, the liquid lens is
best choice as long as variable focus is sufficient in the application and you do not
need a full lens control with aperture control and zoom functionality. In case of full
lens control requirement, please refer to the TRACER series.
The lens is powered and controlled by the camera. The lens can be controlled via
SDK functions or more easily via GenICam property.
Liquid lenses do have some advantages and disadvantages compared to glass
optics:
lAdvantages of liquid lenses
oExtremely robust to mechanical shock (best choice for fast moving robot-
ics) and acceleration
oFast focus (often significantly faster than 10 ms under common con-
ditions)
lDisadvantages of liquid lenses
oLimited resolution
oHigh chromatic aberration
oAny acceleration (gravitational as well as acceleration from movement)
might increase spherical aberration as long as the force is working (will
disappear if force has ceased within several 10ms)
3.3.3 Use of Canon lenses
We are supporting Canon EF lenses. The SVCam-EF adapter gives you the pos-
sibility to mount Canon EF lenses with full control of focus and iris. Canon lenses
3 The EXO series 11

are well known for their optical excellence and combine perfectly to high res-
olution machine vision cameras.
This camera series does have the firmware support already included in the
GenICam tree and provides you with Canon lens control in all GenICam based
software packages.

Before connecting your camera to power, make sure your data cable is connected
properly. Always connect data cable before power.
NOTICE The camera does not support hotplugging
4.3.2 Connect the camera
The camera is powered on by connecting power to the camera.
lConnect the power supply with the Hirose connector.
4 Getting started 13

INFO When using your own power supply (voltage range 10 -25 V DC), see also
Hirose 12-pin layout of the power connector. For power input specifications refer
to specifications.
Generally external power supply for USB3 Vision, CoaXPress (if PoCXP
enabled) or PoE cameras is not needed. Nonetheless, you might want to use a
separate power on the Hirose connector to reduce load on the data port. The
external power on the Hirose connector is the preferred power source.
The power up is defined as follows:
lPower over USB3, CoaXPress port or GigE port (with PoE) or on the Hirose
connector will power on the camera.
lIf power is found on the Hirose connector, camera power supply will switch
to the Hirose connector.
lIf Hirose power supply is cut, camera power supply will switch back to power
over USB3, PoE or power over CXP supply.
INFO Camera power supply is not powering 4I/O LED lights.
4.4 Camera status LED codes
On power up, the camera will indicate its current status with a flashing LED on its
back. The LED will change color and rhythm.
The meaning of the blinking codes translates as follows (current, starting with firm-
ware version b2901):
