While connecting multiple GigE Vision camera with Gigabit Ethernet supported switch, there are some affects including reduce frame rate and camera could not recognize when total amount of trasmitt data from GigE Vision cameras becomes more than 1Gbps.

Please reduce total amount of trasmitt data with reduce frame rata when connecting multiple GigE Vision camera with one Gigabit Ethernet supported switch.

USB3 Vision, GigE Vision and CoaXPress cameras have settings save and load functions.
There are two types of data can be saving onto camera.
Default: Unchangeable Factory default settings
UserSet: Changeable default settings
When loading “Default” data on camera, camera settings go back to factory default settings.
(USB2.0, USB3.0, Camera Link and Opt-C:Link cameras do not have factory default settings on camera.It is necessary to create “Default” settings file before change settings.)

Below is procedure to go back to factory default settings by StViewer.
1. Selects “Default” at “UserSetSelector” under “UserSetControl” on “RemoteDevice” after stop image acquisition.
2. When selecting “Execute” button at “UserSetLoad”, factory default settings are loads from camera.
3. To save factory default settings onto camera, selects “UserSet1” at “UserSetSelector” under “UserSetControl” on “RemoteDevice” then seleccts “Execute” button at “UserSetSave”.

When selecting “Default” at “UserSetDefault” under “UserSetControl” on “RemoteDevice”, power on camera with factory default settings.
When selecting “UserSet1” at “UserSetDefault” under “UserSetControl” on “RemoteDevice”, power on camera with saved UserSet1 settings.

GigE Vision camera and network card(port) on PC are not on same network and GigE Vision cannot use it.
Please check and set IP Address of GigE Vision camera and network card(port) on PC.
IP Address of network card (port) can be confirm on “Interface Information” on “Device Selection” window.
IP Address of GigE Vision camera can be cofirm on “Device Information” on “Device Selection” window.

Please follow below procedure to change IP Address of GigE Vision camera.
1. “Set IP Address” button on right bottom of “Device Selection” window after selects GigE Vision camera to use.
2. Sets IP Address and Subnet Mask at “Device Configuration” on “Set IP Address” window, based on IP Address and Subnet Mask at “NIC Configuration” then selects “OK” button.
Sets same 1st to 3rd octets and different 4th octet IP Address of NIC Configuration, to IP Address of Device Configuration.
Sets same Subnet Mask of NIC Configuration, to Subnet Mask of Device Configration.
3. Selects “OK” button on “Device Selection” window. (If IP Address of Device Configuration is correct, “OK” button becomes selectable)

In the case of below configuration:

1. “Set IP Address” button on right bottom of “Device Selection” window after selects GigE Vision camera to use.
2. Sets “169.254.237.50” at IP Address and “255.255.255.0” at Subnet Mask of Device Configuration on “Set IP Address” window then selects “OK” button.
3. Selects “OK” button on “Device Selection” window.

Jumbo frame is, change packet size from 1,500kbytes to like 9kbytes to reduce number of packets of data transfering.
The data transfering efficenty and stability can be improve with jumbo frame function.
(Jumbo frame is same meaning)

In the case of transfering 8bit 2,048×1,536 image data from GigE Vision camera, amount of data of one frame is about 25,165kbytes.
When disabling Jumbo frame, number of packets of data is about 16,780 packets (25,165,000/1,500).
When enabling 9k Jumbo frame, number of packets of data is about 2,800 packets (25,165,000/9,000).
The number of packets can be reduce significanty with Jumbo frame.
We recommend to use 9kbytes Jumbo frame if network card (port) supports GigE Vision camera.

Please refers “AutoFunctions” sample program for change camera setting.
Please refers sample code that displaying at bottom part of “NodeMap” when selecting function on StViewer for camera parameters.

Sentech SDK includes “Sentech GigE Vision filter driver” for our GigE Vision cameras.
This filter driver does not work with GigE Vision cameras from other camera manufacture.
Sentech SDK also includes device driver for our USB3 Vision cameras.

Please refer “Grab” or “GrabCallback” sample program for image acquisition.
These sample programs are acquring 100 images after connecting camera,
Grab is acquring images with roop process,
GrabCallback is acquring images with callback function.
Please refers “AutoFunction” sample program for camrea setting.

Please refer “GigEConfiguration” or “CameraSideROI” sample program for connecting and change camera settings for GigE Vision camera.
Please refers “SaveAndLoadImage” sample program for image data format conversion.
Please refer “SingleFilter” or “MultipleFilter” sample program for some image processing.

Please refers “SingleFilter” sample program for edge enhancement (sharpness) process.

Both “Grab” and “GrabCallback” sample programs are explain how to connect and acquire image.
The difference is:
“Grab” is acquiring image by roop processing on main thread.
“GrabCallback” is acquiring image with different thread by callback function.

The image data from Bayer CMOS image sensor color camera is before color conversion.
The size of image from color camera and monochrome camera is same.
It is possible to convert to color image data by using color conversion filter that is included in Sentech SDK.
Please refers “SaveAndLoadImage” sample program for how to use color conversion filter.
