Functions and Operations
4.1
GigE Vision Standard Interface
The TM-2030GE cameras are designed in accordance with the GigE Vision standard. Digital images are
transmitted over Cat5e or Cat6 Ethernet cables. All camera functions are also controlled via the GigE Vision
interface.
The camera can operate in continuous mode, providing an endless stream of images. For capturing individual
images, related to a specific event, the camera can also be triggered. For precise triggering, it is recommended
to use a hardware trigger applied to the Hirose 12-pin connector. It is also possible to initiate a software
trigger through the GigE Vision interface. However, when using a software trigger, certain latency inherent to
the GigE interface must be anticipated. This latency, that manifests itself as jitter, greatly depends on the
general conditions and traffic on the GigE connection. The frame rate described in this manual is for the ideal
case and may deteriorate depending on conditions.
When using multiple cameras (going through a switch and/or a single path) or when operating in a system with
limited transmission bandwidth the Delayed Readout Mode and Inter-Packet Delay functions can be useful.
4.2
GigE Vision-Aware Software
A GigE Vision camera can be controlled by any software that understands the protocol. At JAI we provide the
JAI GigE Vision SDK and Control Tool to interface with our cameras. The remainder of the manual will show
screenshots of the JAI Control Tool, but other 3rd party software will provide similar functionalities.
4.3
Recommended Network Configurations
Although the TM-2030GE cameras conform to Gigabit Ethernet (IEEE 802.3) not all combinations of network
interface cards (NICs) and switches/routers are suitable for use with the GigE Vision compliant camera.
4.3.1
Verified Network Interface Cards (NICs)
At the time of publishing this document these combinations have been verified:
NIC: Intel Pro/1000MT, Pro/1000GT, Pro/1000PT.
CPU: Intel Core 2 Duo 1.84Ghz.
Memory: 2 GB
Video Card: video card on PCI Express bus with at least 256MB of VRAM.
Functions such as screen saver and power save should not be used. Unnecessary applications such as Word,
Excel or others should not be used.
