Description
he AVIIVA EM2/EM4 is designed to set new standards for line scan cameras in term of speed and
image quality. With resolutions of up to 4096 pixels, and the design of new CCD image sensors, it delivers
state of the art performance, without compromises.
Its rich built-in features, such as automatic FCC, LU or automatic tap balance, are positioning it as the
perfect choice for high demanding Machine Vision Applications (BA0)
A specific rectangular-pixels sensor version (BA9) is dedicated to specific applications as Optical
Coherence omography (OC ) or Spectrometer.
he EM2/EM4 benefits from e2v’s long experience in imaging, and the proven qualities of the AviivA
family : performances, reliability, and high precision mechanical design.

e2v recommends using the same configuration to ensure the compliance with the following standards.
4.1 CE Conformity
he AVIIVA EM2/EM4 cameras comply with the requirements of the EMC (European) directive
2004/108/CE (EN50081-2, EN 61000-6-2).
4.2 FCC Conformity
he AVIIVA EM2/EM4 cameras further comply with Part 15 of the FCC rules, which states
that: Operation is subject to the following two conditions:
his device may not cause harmful interference, and
his device must accept any interference received, including interference that may cause
undesired operation
his equipment has been tested and found to comply with the limits for Class A digital device,
pursuant to part 15 of the FCC rules. hese limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in a commercial environment. his
equipment generates, uses and can radiate radio frequency energy and, if not installed and used in
accordance with the
instruction manual, may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference in which case the user will be
required to correct the interference at his own expense.
Warning: Changes or modifications to this unit not expressly approved by the party responsible
for compliance could void the user's authority to operate this equipment.
4.3 RoHs Conformity
AVIIVA EM2/EM4 cameras comply with the requirements of the RoHS directive 2002/95/EC.

he contains of the Camera box is the following :
here is no CDROM delivered with the Camera : his User Manual , but also the Pleora PureGeV
Package, DemoGeV and all documentation associated to the GigE Vision, GenICam standards can
be downloaded from the web site : his ensure you to have an up-to-date version.

Setting up in the system
Vocabulary :
w
= size of the sensor line (40,96mm for the 4k 10µm)
FOV
= Field Of View (width of the web inspected by the sensor line) in mm.
L
= Working distance (from the Lens to the Web) in mm.
f
= focal distance of the lens in mm.
S
= Speed of the web in mm/s
We have :
w/FOV = f/L
he ratio M = w/FOV is called Magnification.
he FOV is grabbed by 4096 pixels in the width.
In order to get a ratio of 1 :1 in your image, at the web speed of S, your line rate has to be set :
Line Rate = (S/FOV) x 4096
Ex : if the FOV = 11 cm (110mm) and the speed of the web is S= 0,3 m/s (300mm/s) the line rate will be :
Line Rate = (300 /110) x 4096 = 11170 Lines/s.
If you use a 60mm lens, the working distance will be : L = (60 x 110) / 40,96 = 161mm.
his will certainly require a macro lens.

5CAMERA SOFTWARE INTERFACE
5.1
Control and Interface
As all the e2v Cameras, the AVIIVA II is delivered with the friendly interface control software
COMMCAM.UCL (as “Ultimate Camera Link”) which is based on the GenICam standard
COMMCAM recognizes and detects automatically all the UCL Cameras connected on any transport layers
(Camera Link or COM ports) of your system.
Once connected to the Camera you have an easy access to all its features. he visibility of these features
can be associated to three types of users: Beginner, Expert or Guru. hen you can make life easy for
simple users.
