GigE Camera and Drivers Features V3.0.0

This document is a master document for all Allied Vision GigE camera models and is NOT camera specific
GevHeartbeatTimeout [Integer] R/W
For Vimba v1.3 or higher only The driver sends heartbeat packets to the camera. If a heartbeat packet is not
received within GevHeartbeatTimeout, the camera assumes the host has
closed its controlling application or is dead, and closes its stream and control
channel.
This parameter may need to be increased if stepping through code in a debug-
ger, as this prevents the driver from sending heartbeat packets.
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.
Display name: Heartbeat Interval
Range:[500–10000] Default: 3000 Unit: ms
Display name: Heartbeat Interval
Range:[500–5000] Default: 3000 Unit: ms
Note

This parameter can be increased significantly to
bypass problems when debugging applications.
Range: [Camera dependent] Default:
Camera dependent Unit: Bytes
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.
Unit: Bytes
