Point Grey Flea3 GigE Technical Reference
2 Flea3 GigE Installation
n
Dynamic (DHCP)
—Both the camera and the adapter are set to automatically obtain an IP address. This means that
the IP address will dynamically change (within a range) every time the camera or computer is restarted. It may
take up to one minute for the IP address to resolve and the camera to enumerate.
n
Default (LLA)
—Both the camera and the adapter use a default IP address from the link-local address block
169.254.x.x.
The camera assigns its current IP address in the following sequence:
1.
Persistent
—Uses the defined IP address. If not available, then;
2.
DHCP
—Attempts to find a dynamic IP address. If not available, then;
3.
LLA
—Uses the default IP address.
The GigE Configurator can automatically force an IP address refresh. This detects the IP address of the Network Interface
card and automatically sets the camera’s IP address relative to the card.
The FlyCap program can be used to test your camera settings and verify operation. From the camera selection window,
you can also automatically force an IP address refresh.

2.4.3
Allocating Bandwidth
The User Datagram Protocol (UDP) used by the GigE Vision standard provides no guaranteed transmission or fixed
timing mechanism. Therefore, bandwidth must be managed by adjusting packet size and packet delay, based on desired
resolution and frame rate.
2.4.3.1
Packet Size
The stream channel packet size (SCPS) sets the size, in bytes, of the packet to be sent out by the camera. IP, UDP and
GVSP headers are included in this size. The default packet size is 1400 bytes.
