Acquisition Control AW00118302000
134 Basler racer GigE
8.4 Frame Transmission Time
As mentioned in earlier sections of this chapter, each time that a complete frame has been
accumulated in the camera’s frame memory, the frame will be transmitted from the camera to your
host PC via the camera’s Ethernet network connection. The image data in the frame will be
packetized and transmitted in compliance with the mechanisms described in the GigE Vision
standard.
For more detailed information about receiving the frames as they arrive in your host PC, refer to the
Basler pylon Programmer’s Guide and API Reference. The sample programs included with the
pylon software development kit (SDK) also provide more detailed information about handling
incoming image data in your host PC.
For more information about managing the bandwidth of the Ethernet network connection between
your camera(s) and your host PC, see Section 5 on page 37.
You can calculate the approximate time that it will take to transmit a frame from the camera to the
host PC by using this formula:
Note that this is an approximate frame transmission time. Due to the nature of the Ethernet network,
the transmission time could vary.
Due to the nature of the Ethernet network, there can be a delay between the point where a complete
frame is acquired and the point where transmission of the acquired frame begins. This start delay
can vary from frame to frame. The start delay, however, is of very low significance when compared
to the transmission time.
For more information about the Payload Size and Device Current Throughput parameters, see
Section 5.1 on page 37.
