Parameter
Description
IP Configuration Mode
Default is DHCP/LLA mode. Select Persistent IP if manually setting the
Genie IP address via the IP Address parameter.
IP Address
Displays the Genie IP address.
Allows setting the IP address when the mode is Persistent IP.
Network Configuration
Mode
Specifies the Network Configuration Mode as either Automatic, Manual,
or Optimize. In general use Optimize mode. Some computers,
especially laptops, may require manual optimization of network
parameters.
The following parameters can be modified when Manual mode is
selected.
Inter-Packet Delay (in
sec)
Specifies the inter-packet delay inserted by the Genie, in seconds. The
range of permitted values is 0.000000 to 0.065535. The inter-packet
delay is the minimum time interval between two successive packets.
This can be increased if the NIC is unable to keep up with packet
arrivals (thus dropping packets–seen as video noise). This situation
can occur with multiple triggered cameras connected via an Ethernet
switch, to one NIC. .
Packet Size (in bytes)
Specifies the maximum packet size, in bytes. The range of possible
values is 576 to 1500, in increments of 4 bytes when the NIC does not
support jumbo packet. The maximum is currently 9000 bytes when
jumbo packets are supported (refer to the Teledyne DALSA Network
Imaging package manual to enable jumbo packets on the NIC). In
most situations, use the largest possible packet size supported by your
network elements. In order to support jumbo packets, all intermediate
network elements must support them, otherwise they will simply be
silently discarded and no image data will reach the PC.
Maximum Packet Resend
Sets the percentage of packets that can be resent for each frame. This
is used to ensure the streaming data (including resends) does not
exceed the Ethernet link capacity. As an example, a system capturing
at 80 MB/s can allow 25% of packet resends without exceeding 100
MB/s (about the maximum capacity of a gigabit Ethernet link).
Inter-Packet Timeout (in
sec)
Specifies the inter-packet timeout period used by the GigE server
running on the host computer (in seconds). The inter-packet timeout is
the amount of time the GigE server will wait between successive
packets. If the inter-packet timeout expires, the GigE server will issue
a packet resend request to the camera.
The range of permitted values is 0.000000 to 0.65535. By default this
value is greater than (and must be greater than) the Inter-Packet
Delay inserted by the Genie (described above). Else the GigE server
will force packet resends when none may be required. Increasing the
timeout period is required when a NIC has a number of Genie cameras
connected via an Ethernet switch, and packet resends can be avoided
if the GigE server delays assuming data is lost.
