transmitted to the wire-speed of 1 Gigabit per second. Therefore, inter-packet delay is typically only used when
multiple detectors are connected to the same port of the network card, through an Ethernet switch.
It is important to consider that inter-packet delay inserts a minimum delay between image packets to spread packet
transmission over a longer period of time. This can directly impact system latency as more time than could be
necessary is put in between those packets. The best approach for real-time imaging is to dedicate a different network
port to each detector. This way, the inter-packet delay can be eliminated in many cases.
Some network equipment also supports the optional IEEE802.3 PAUSE mechanism. This is a low-level handshake
to ensure the receiver of the packets is not overwhelmed by the amount of data. It can propagate a pause signal back
to the transmitter, asking to momentarily stop the data transmission (with a possible impact on the overall system
latency). Again, by combining network equipment that can operate at wire-speed and allocating a different network
interface port for each detector in the system, we can ensure these pause requests will not be used.
Connecting
1. After the install is complete, plug in the detector communication cable.
2. Power up the detector.
3. After powering up the detector, the application automatically detects the detector. This may take up to 1 minute.
Wait until the detector connected indicator in the task bar (shown below) has confirmed that a connection has been
established (the red cross over the camera icon disappears).
Checking detector status and information in Gigabit Ethernet
When you add or remove a detector from the network, it is automatically detected by the GigE server. A manual
network scan can also be launched by right-clicking the camera icon and selecting “Scan Network” from the menu
options. This action will refresh the information of the device connected to the network.
After the detector connection has been established, the status of the connection can be displayed by double-clicking
the camera icon in the task bar. The device status window displays the serial number of the detector that has been
detected on the network and its current status. Additional information with respect to the detector model, serial
number and MAC address is also displayed.
The user can also view the detector and the PC IP addresses in this window. The default assigned detector IP address
can be modified using the Teledyne DALSA Network Configuration Tool, which is part of the installation package.
