AD-081GE
25
Minimum PC requirements are as follows in order to fulfill the above conditions:
Intel Core 2 Duo , 2.4 GHz or better
At least 2 GB memory
Video Card with PCI Express Bus x 16, VRAM better than DDR2 with 256 MB or more, and
display capability of 2560 x 1600
Windows XP, SP2 (32bit)
Functions such as screen saver and power save should not be used. Unnecessary applications
such as Word, Excel or others should not be used.
Note: Pentium 4 type PC is not recommended due to dependency on chip set bus performance.

In the case of using Jumbo Frames (16K), the packet data will be improved by 2 %.
For AD-081GE, the jumbo frame size can be a maximum 16020 Bytes (factory setting is 1476
Bytes). The NIC must also be set to support Jumbo Frames (refer to section 10.2.4).
Based on the Pixel Type, the packet size may be automatically adjusted inside the camera to
its most suitable value .
To ensure the integrity of packets transmitted from the camera, it is recommended to follow
these simple guidelines:
these simple guidelines:
1. Whenever possible use a peer-to-peer network.
2. When connecting several cameras going through a network switch, make sure it is
2. When connecting several cameras going through a network switch, make sure it is
capable of handling jumbo packets and that it has sufficient memory capacity.
3. Configure inter-packet delay to avoid congestion in network switches.
4. Disable screen saver and power save functions on computers.
5. Use high performance computers with multi-CPU, hyper-thread and 64-bit CPU, etc.
6. Only use Gigabit Ethernet equipment and components together with the camera.
7. Use at least Cat5e and preferably Cat6 Ethernet cables.
8. Whenever possible, limit the camera output to 8-bit.

Note for setting packet size
The packet size is set to 1428 as the factory default. Packet size can be modified in the GigE
Vision Transport Layer Control section of the camera control tool (see below). For AD-081GE,
users may enter any value for the packet size and the value will be internally adjusted to an
appropriate, legal value that complies with the GenICam standard. Thus, the actual packet
size may be different than the value entered by the user.
Caution: do not set the packet size larger than the maximum setting available in the NIC or
switch to which the camera is connected (see section 10.2.4). Doing so will cause output to
be blocked.
