The Multicast class provides methods for configuring the multicast mode of a GigE uEye camera or open a virtual multicast camera. The camera itself must be opened by the master PC to be additionally available as a virtual multicast camera. Only then, the virtual multicast camera is free and available for other client PCs.
The classes and methods are divided as active and passive multicast methods. Active methods changes parameters in the camera. For this purpose the camera must be available (but not opened). Passive multicast methods are used to open a virtual multicast camera by a client in read-only mode.

The multicast function is supported by driver 4.50 for the first time. The camera models UI-526x, UI-536x, and UI-537x of the GigE uEye CP camera family currently do not support the multicast mode. |
For multicast mode, you must configure the camera with a persistent IP address (PersistentIp) and a multicast IP adress. Valid multicast IP addresses are from 224.0.0.1 to 239.255.255.255.
The following restrictions apply to multicast cameras:
•The persistent IP address of the GigE uEye camera must be in the subnet of the network adapter. Possible clients of the virtual multicast camera must also be in this subnet.
•If the master changes the camera settings, these changes also apply on the image of the clients. The clients can only change camera-independent functions (e. g. software gamma or software LUT).
•The software hot pixel correction does not work on client PCs.
•If multicast mode is enabled (SetEnable()), this may affect the performance of the API application.

If using a firewall the rules must be set in that way that the application can receive network packets. Security programs (e. g. antivirus programs) may have a negative impact on the performance of virtual multicast cameras. |
The following classes and methods exist:
