AW00097603000 Network Related Camera Parameters and Managing BandwidthBasler aviator GigE 295Appendix BNetwork Related CameraParameters and ManagingBandwidthThis section describes the camera parameters that are related to the camera’s performance on thenetwork. It also describes how to use the parameters to manage the available network bandwidthwhen you are using multiple cameras.B.1 Network RelatedParameters in the CameraThe camera includes several parameters that determine how it will use its network connection totransmit data to the host PC. The list below describes each parameter and provides basicinformation about how the parameter is used. The following section describes how you can use theparameters to manage the bandwidth used by each camera on your network.Payload Size (read only)Indicates the total size in bytes of the image data plus any chunk data (if chunks are enabled) thatthe camera will transmit. Packet headers are not included.Stream Channel Selector (read/write)The GigE Vision standard specifies a mechanism for establishing several separate stream channelsbetween the camera and the PC. This parameter selects the stream channel that will be affectedwhen the other network related parameters are changed.Currently, the cameras support only one stream channel, i.e., stream channel 0.Packet Size (read/write)As specified in the GigE Vision standard, each acquired image will be fit into a data block. The blockcontains three elements: a data leader consisting of one packet used to signal the beginning of adata block, the data payload consisting of one or more packets containing the actual data for thecurrent block, and a data trailer consisting of one packet used to signal the end of the data block.The packet size parameter sets the size of the packets that the camera will use when it sends thedata payload via the selected stream channel. The value is in bytes. The value does not affect the
