2.1 Power Supply
PxVision needs 24 VDC for power supply:
The Max current is 0,105 A, this is considered for full load with all ILUMINATION LED ON
2.2 Ethernet Port
The PxVision system uses a ETHENET RJ45 port for PC connection
It is recommended Ethernet cable cat. 5e with shield
2.3 PC Connection
The PC connection is by Ethernet port
The PC IP address must be on same category of PxVision system, therefore if PxVision has an IP address of 10.0.0.82
the PC must have a STATIC IP (eg.) of 10.0.0.80.
For setting the IP address of PxVision use the PxVisionBrowser application.
For setting a new IP address is necessary to know the current IP address, if it is unknow, see the procedure se
PARAMETERS RESET.
If the IP is known run PxVisionBrowser and execute the following step:
1) Press
2) Press
3) Press

Insert the new IP address and press SAVE.
Is necessary to restart PxVisionBrowser for update the new IP address
2.4 Parameters Reset
If the IP address of PxVision is unknown is possible to RESET the parameters to default:
1) Turn on PxVision without PC connection
2) With a pointed object “like to paper clip” press and hold the RESET button for 3-4 Sec.
3) During this operation the LED YELLOW L1 is blinking
4) Release the button RESET
5) Now the new IP address is set to 10.0.0.82
2.5 Status Led
The 3 LED show the following status:
L1 Yellow Led Blink when the PC download the images from PxVision (used also for RESET procedure)
L2 Green Led Blink when PxVsion is ready. If OFF the system has problems
L3 Red Led Power On
2.6 Illumination Led
The PxVision has 8 LED withe light for objects illumination.
Can be ON a single LED with variable Power from 0 to 100%.
For management LED use PxVisionBrowser.
WARNING
SELECT ALWAYS DLL PxPlusCamera.dll AFTER SAVE

2.6.1 Illumination LED limitation
In some situation the illumination could generate “areas of reflection light” that can create a noise in the
acquisition image
See the following images.
2.7 S.O.
As we can see the image a) is acquired with LED off and the image b) with LED On.
In the image b) there are an areas of reflection light generated by LED ILLUMINATION in the camera lens.
The acquisition image could be wrong.
In this situation the best solution is use an external light without reflection or natural illumination
a) Image with LED Off
b) image with LED On

2.9 Focus Lens
PxVision can mounting two lens types:
Autofocus or Fixed Focus.
2.9.1 Autofocus
These lenses are motorized and can used in AUTOFOCUS MODE, therefore the camera make an automatic
procedure of focus on the object acquired, or in DIGITAL MANUAL FOCUS by PxVisionBrowser.
Enable the Autofocus mode
Or Disable the Autofocus mode and use the Slider for Manual Digital Focus
Difference from Autofocus and Manual Focus
When the camera is in Autofocus Mode, the object is focused automatically by camera, this generate a delay time
before the image will be available (more or less 1 sec) and in some case the interested object could not be focused.
Use Manual Focus for eliminate this problem.
However the Autofocus Mode is necessary when PxVision is mounted on “Mobile Axis”that can frame objects
from different distances.

PXVISION
2.9.2 Fixed Focus
These lenses have a fixed focus and not are motorized, therefore the focus must be set in manual mode based a
focal length of lens and object distance.
Manul Focus Procedure
By PxVisionBrowser enable START TEST with MultiFrame checked from menù Camera Setting
The system start to acquire images in continuous mode.
1) Remove the screw from lens.
2) Rotate the lens in CW or CCW direction up to the image is focused.
3) Insert the screw in the lens and block it with a light pressure.
WARNING
IF THE LENS IS TO END OF SCREW THREAD OR OUT OF IT, MUST
OUTDISTANCE THE CAMERA, FROM THE OBJECT
