GVCPHBInterval [Integer] R/W
For Vimba v1.2.1 or lower The driver sends a heartbeat request packet to the camera every GVCPHBIn-
terval milliseconds. If the camera fails to respond to the heartbeat request,
a retry is sent “GVCPCmdTimeout” ms later. After “GVCPCmdRetries”
retries with no response, a camera unplugged event is returned by the driver.
GevSCPSPacketSize [Integer] R/W
This parameter determines the Ethernet packet size. Generally, this number
should be set to as large as the network card (or other involved active network-
ing components) will allow. If this number is reduced, then CPU loading will
increase. These large packet sizes (>1500) are called jumbo packets/frames in
Ethernet terminology. If your Gigabit Ethernet network card does not support
jumbo packets/frames of at least 8228 bytes (the camera default on power
up), then you will need to reduce GevSCPSPacketSize parameter of the
camera to match the maximum jumbo packet size supported by your Gigabit
Ethernet interface. A GevSCPSPacketSize of 1500 is a safe setting which
all GigE Ethernet network cards support.
NonImagePayloadSize [Integer] R
Maximum size of chunk data, not including the image chunk, in the image block
payload. If ChunkModeActive = False, NonImagePayloadSize = 0.
Ptp
Precision Time Protocol (PTP) manages clock synchronization of multiple
devices across an Ethernet network. Once the clocks of devices such as cameras,
PCs, and sensors are synchronized, future software based triggers can be syn-
chronized within 2 µs. On AVT GigE cameras, the device clock is represented by
the camera GevTimeStampValue feature.
Display name: Heartbeat Interval
Units: ms
Note

This parameter can be increased significantly to
bypass problems when debugging applications.
Range: [Camera dependent] Default:
Camera dependent Units: Byte
Note

If you are seeing all black images, or all frames reported
as StatFrameDropped and zero images reported as
StatFrameDelivered, you will likely need to
decrease this parameter.
Units: Byte
