Before using USB 3.0 camera
EMVA 1288
With regard to signal to noise ratio in this manual, specifications measured by EMVA 1288 are used
together with specifications by a traditional measurement method.
EMVA 1288 is a more complete measurement that considers multiple noise sources, including
random noise, pattern noise, and shading. Additionally, EMVA 1288 incorporates temporal variances
in pixel output by capturing 100 frames of data and computing the RMS variations over the captured
frames. Because of the comprehensive nature of the noise analysis and the additional consideration
for RMS variances over time, EMVA 1288 SNR measurements are inherently lower than the traditional
SNR measurements given by manufacturers. However, the comprehensive nature combined with
rigid test parameters, means that all manufacturers are measuring their products equally and EMVA
1288 tested parameters can be compared among different manufacturers’ products.
In order to learn more about EMVA 1288, please visit http://www.emva.org
Interface
The EL-2800-USB employs a USB 3.0 interface and is in the process of being certified for compliance
with the USB3 Vision standard. USB3 Vision is a new standard interface for machine vision
applications being developed and managed by the AIA (Automated Imaging Association). USB3 Vision
uses USB 3.0 ports that will soon be standard on most PCs (with Windows 7 service pack and Windows
8 native support expected soon). Components from different manufacturers will easily communicate
with each other.
USB3 Vision also supports the GenICamTM standard which is managed by the EMVA (European Machine
Vision Association). The purpose of the GenICam standard is to provide a common program interface
for various machine vision cameras. By using GenICam, cameras from different manufacturers can
seamlessly connect in one platform.
The maximum transfer speed of USB 3.0 is specified at 5.0 Gbps, however effective bandwidth is
reduced by a number of factors including pixel format conversions and the physical interface
components used. The USB3 Vision standard specifies a bandwidth of 2.8 Gbps or greater. Maximum
cable length for passive cables is five meters, but this can be made longer using active cables.
As for the USB connector, EL-2800-USB uses a Micro B connector which complies with USB 3.0. This
connector has an additional 5-pin plug “stacked” on the side of a standard USB 2.0 Micro B
connector. However, USB 2.0 cannot be used with the EL-2800-USB.
Power supply
Although the USB 3.0 interface is capable of supporting both data and power, EL-2800-USB requires
both +5V and +12V. A separate power supply unit must be connected to the 12-pin connector for
providing +12V.
Computer used for EL-2800-USB series
It is necessary to use a PC equipped with a USB 3.0 interface. It is also recommended to use a PC
equipped with slots of better than PC Express 2.0 x 8. Please note that the EL-2800-USB may not
work properly depending on the chipset used in the PC.

1. General
The EL-2800M-USB and EL-2800C-USB are new cameras in JAI’s Elite Series. They provide high
picture quality, such as high sensitivity and low noise, suitable for machine vision applications. The
EL-2800M-USB is a monochrome progressive scan CCD camera and the EL-2800C-USB is the
equivalent Bayer mosaic progressive scan CCD camera. Both are equipped with a 2/3 inch CCD
sensor offering 2.83 million pixels resolution and a 4:3 aspect ratio. They provide 54.6 frames per
second for continuous scanning with 1920 x 1440 full pixel resolution for both monochrome and raw
Bayer output. 8-bit, 10-bit, or 12-bit output can be selected for both monochrome and Bayer
outputs.
The new cameras feature a USB 3.0 interface. A full pixel readout, partial scan readout, or binning
mode (monochrome only) can be selected depending on the application.
EL-2800M-USB and EL-2800C-USB have various comprehensive functions needed for automated
optical inspection applications, such as solid state device inspection or material surface inspection.
They incorporate video processing functions such as a look-up table, shading compensation, and
blemish compensation in addition to fundamental functions such as trigger, exposure setting and
video level control.
As a common Elite Series feature, a new connector for lens control is employed. EL-2800M-USB and
EL-2800C-USB support P-iris and motor-driven lenses as standard lens control capabilities. Factory
options are available to configure this connector to support DC iris systems as well as provide a
video iris output signal, or to provide additional TTL IN and OUT lines.

5. Input and output
5.1 USB 3.0 Interface Specifications
The EL-2800-USB employs a USB 3.0 interface for video and data transfer. USB 3.0 is an upgraded
version of USB 2.0 widely used in the industry. Its transfer rate is 5 Gbps, which is 10 times faster
than the 480 Mbps rate of USB 2.0. USB 3.0 employs a full-duplex system which executes both
transmitting and receiving at the same time. USB 3.0 has downward compatibility to USB 2.0 but in
the EL-2800-USB, USB 2.0 cannot be used because the performance is not guaranteed.
The connector used for USB 3.0 in the EL-2800-USB is a Micro B Type connector with a USB 3.0 form
factor.

5.6Pulse Generator
The EL-2800-USB has a frequency divider using the internal pixel clock as the basic clock and two
pulse generators. In each Pulse Generator, various Clear settings are connected to GPIO. The
following shows Pulse Generator default settings.
Table - 10 Pulse Generator default settings
5.6.1 Clock Pre-scaler
Clock pre-scaler (Divide Value) can set the dividing value of the frequency divider (12-bit
length) and the pixel clock is used for this. Two built-in pulse generators work by the same
clock. In the EL-2800-USB, the internal pixel clock is 54 MHz.
5.6.2 Pulse Generator Selector
This is where you select one of the 2pulse generators in order to set or modify its parameters.

Note:When Pulse Generator Repeat Count is set to “0”, the camera is operating in Free Running mode.
However, based on the above default settings (Length=1, Start Point=0 and End Point=1), Pulse Generator stops at
High output. Therefore, if Start Point=0 and End Point=1 are configured, Length should be “2”as the minimum active
width.
