8. Functions and Operations
8.1. GigE Vision Standard Interface
The CM-040GE/CM-040GE-RA and CB-040GE/CB-040GE-RA are designed in accordance with the
GigE Vision standard. It transmits digital images 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 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.
8.2. Recommended Network Configurations
Although the CM-040GE/CM-040GE-RA and CB-040GE/CB-040GE-RA 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.
JAI will endeavor to continuously verify these combinations, in order to give users the widest
choice of GigE components for their system design.
