Shielded Ethernet Cable Requirements
In order to achieve EMC compliance, the Spyder 3 camera requires the use of shielded
CAT5e or CAT6 Ethernet cables.
2.3 Drivers: Overview
High Performance Driver Mode
In high-performance mode, the Spyder 3 GigE works with the High-Performance IP
Device Driver to transfer data between cameras and PCs with very low, predictable
latency at rates of up to 1 Gb/s (100 MB/s). The video data is streamed directly into PC
memory using almost no PC CPU resources. This leaves the CPU free to process
applications.
To achieve this performance level, PCs must be equipped with a GigE network interface
(also referred to as a network adapter) based on Intel’s 82540 chip. Many motherboard
manufacturers are designing this chip directly into their board in “LAN on the
motherboard (LOM)” implementations. Alternately, an Intel 82540-based network
adapter, also known as a network interface card, can be slotted into a PC.

Note:
The DALSA NetLink IP Device Driver supports LOM implementations, but the PCI
identification number for these may be different. Contact DALSA to obtain a driver
installation file compatible with LOMs.
Standard Driver Mode
In standard mode, the Spyder 3 GigE operates with any vendor’s Ethernet network
adapter. The driver shipped with the adapter transfers the data to the Windows network
stack, which handles IP communications tasks.
Standard mode is recommended for applications where flexibility is more important than
performance. The Windows network stack uses significant levels of CPU processing
power to transfer data to memory, which can result in lost packets, severely degrading
performance.
Standard mode is thus suitable for applications that require bandwidths of only 100 Mb/s
or less. If this mode is used with bandwidths of 1 Gb/s, application performance will
greatly degrade when CPU usage hits 100%. Additionally, at high rates like these,
insufficient CPU resources may be available to process or even display images.
