Introduction

Interface

The EL-2800M-CXP and EL-2800C-CXP employ CoaXPress as an interface system. In order to connect
the camera to a PC, it requires the use of a Frame Graber board and the appropriate coaxial
cable(s). The maximum video transfer rate per coaxial cable is 6.25 Gbps (CXP-6). The maximum
rate per cable supported by the EL-2800 is 3.125 Gbps (CXP-3) but for RGB output, 6.25 Gbps is
supported. In addition to video information, power and control signals can be transferred to the
camera over this interface. For detailed specifications, please refer to “JIIA-NTF-001-2010”
published by Japan Industrial Imaging Association, http://www.jiia.org.

Frame grabber boards used with EL-2800 series

As the EL-2800M-CXP and EL-2800C-CXP employ CoaXPress as an interface system, a
CoaXPress-compliant frame grabber board is required. Each camera has a single CoaXPress
interface connector.

Cables used with EL-2800 series

For the CoaXPress interface, coaxial cables are used. In the EL-2800M-CXP and EL-2800C-CXP, they
use 75Ω 1.0/2.3 DIN receptacles (Amphenol ACX1785-ND or equivalent). The coaxial cable used to
connect the camera must have a 75Ω 1.0/2.3 DIN-type plug at the camera side. An ordinary BNC
cable cannot be used.

1. General

The EL-2800M-CXP and EL-2800C-CXP 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-CXP is a monochrome progressive scan CCD camera and the EL-2800C-CXP 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 54.7 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
EL-2800C-CXP is also capable of performing in-camera color interpolation to produce 24-bit (8-bit
per color) RGB output at 54.7 in Quad Tap Sensor Geometry. The new cameras feature a CoaXPress
interface which uses coax cable with the capability of supplying power through the cable. The
EL-2800M-CXP and EL-2800C-CXP use a single coaxial cable interface. A full pixel readout, partial
scan readout, or binning mode (monochrome only) can be selected depending on the application.

EL-2800M-CXP and EL-2800C-CXP 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-CXP and
EL-2800C-CXP 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 CoaXPress interface standard

The EL-2800M-CXP and EL-2800C-CXP use CoaXPress as their interface. CoaXPress is a
PLUG-AND-PLAY interface and connects the camera and the frame grabber board by coaxial cable(s).
Its maximum transfer rate is 6.25 Gbps per one coaxial cable. Additionally, CoaXPress interface
supports power supplied through the coaxial cable as well as communication signals. In the
CoaXPress interface, multiple coaxial cables can be used in order to achieve a faster transfer rate or
a reduced transfer rate can be used to extend the cable length.
In the EL-2800M-CXP and EL-2800C-CXP, a single coaxial cable system is used.

Fig.3 CoaXPress interface

The distance between camera and frame grabber board depends on the bit rate of the video and the
cable used. Among the unique features of CoaXPress is its ability to supply DC power and provide
trigger timing accuracy.
The maximum power supply per one cable is 13W with DC+24V voltage. The accuracy of the trigger
is ±2 ns at 3.125 Gbps.
The CoaXPress compliance labeling is assigned to the following five cable types and the maximum
bit rate and transmission length is indicated in the table below.

In the EL-2800M-CXP and EL-2800C-CXP, the maximum bit rate is 3.125 Gbps for Monochrome and
Bayer color and 6.25 Gbps for RGB color per one cable.

5.5 Pulse Generator

The EL-2800-CXP has a frequency divider using the pixel clock as the basic clock and four 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

5.5.1 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. Four built-in pulse generators work by the same
clock. In the EL-2800M/C-PMCL, the pixel clock is 108 MHz.

5.5.2 Pulse Generator Selector

This is where you select one of the 4 pulse 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.

Fig.8 Pulse Generator Pulse construction

5.5.3 Pulse Generator Length

Set the counter up value (number of clocks, refer to Table 12) for the selected pulse generator.
If Repeat Count value is “0”, and if Pulse Generator Clear signal is not input, the pulse

generator generates the pulse repeatedly until reaching this counter up value.

5.5.4 Pulse Generator Start Point

Set the active output start count value for the selected pulse generator.
However, please note that a maximum 1 clock jitter for the clock which is divided in the clock
pre-scaler can occur.

5.5.5 Pulse Generator End Point

Set the active output ending count value for the selected pulse generator.

5.5.6 Pulse Generator Repeat Count

Set the repeating number of the pulse for the selected pulse generator. After Trigger Clear
signal is input, the pulse generator starts the count set in Repeat Count. Accordingly, an active
pulse which has a start point and end point can be output repeatedly.

However, if Repeat Count is set to“0”, it works as Free Running counter.

5.5.7 Pulse Generator Clear Activation

Set the clear conditions of clear count pulse for the selected pulse generator.

5.5.8 Pulse Generator Clear Sync Mode

Set the count clear method for the selected pulse generator.

In Async Mode, if the clear signal is input during the length setting value, the counter will stop
counting according to the clear signal input.
In Sync Mode, if the clear signal is input during the length setting value, the counter will continue
to count until the end of the length setting value and then clear the count.

Both modes clear the repeat count when the counter is cleared.
