Introduction
GigE Vision is the new standard interface using Gigabit Ethernet for machine vision applications
and it was mainly set up by AIA (Automated Imaging Association) members. GigE Vision is
capable of transmitting large amounts of uncompressed image data through an inexpensive
general purpose LAN cable for a long distance.
GigE Vision also supports the GenICamTM standard which is mainly set up 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 manufactures can seamlessly connect in one platform.
For details about the GigE Vision standard, please visit the AIA web site,
www.machinevisiononline.org and for GenICam, the EMVA web site, www.genicam.org.
JAI GigE Vision cameras comply with both the GigE Vision standard and the GenICam standard.
Before using GigE Vision camera
All software products described in this manual pertain to the proper use of JAI GigE Vision
cameras. Product names mentioned in this manual are used only for the explanation of
operation. Registered trademarks or trademarks belong to their manufacturers.

Camera Operation
1. General
This manual covers the digital 2-CCD progressive scan camera AD-131GE.
The AD-131GE is a GigE Vision compliant camera, belonging to the JAI C3 Advanced family. The
AD-131GE employs two 1.3 megapixel Monochrome CCDs utilizing prism optics in order to
achieve advanced functions such as High S/N mode which improves the signal-to-noise ratio by
3dB; High Dynamic Range mode which achieves 120dB; and High Frame Rate mode which
doubles the normal frame rate while maintaining the same clock speed and S/N ratio.
The AD-131GE provides a standard frame rate of 31 frames/second at full resolution. Using
partial scan, the camera can achieve faster frame rates up to 145 fps (8 lines height).
The 1/3" CCDs with square pixels offer a superb image quality. The high-speed shutter function
and asynchronous random trigger mode allows the camera to capture high quality images of
fast moving objects.
The camera features a built-in pre-processing function which includes blemish compensation,
shading compensation, LUT/gamma correction and knee control.
The AD-131GE also complies with the GenICam standard and contains an internal XML file that
is used to describe the functions/features of the camera. For further information about the
GigE Vision Standard, please go to www.machinevisiononline.org and about GenICam, please
go to www.genicam.org.
As an application programming interface, JAI provides an SDK (Software Development Kit). This
SDK includes GigE Vision Filter Driver, JAI Control tool, software documentation and code
examples.
The JAI SDK can be downloaded from www.jai.com.
The latest version of this manual can be downloaded from www.jai.com
For camera revision history, please contact your local JAI distributor.
2. Camera nomenclature
The standard camera composition consists of the camera main body and C-mount protection
cap.
The camera is available in the following versions:
AD-131GE
Where Astands for "Advanced" family, Dstands for "Dual CCD", 131represents the resolution
"1.3 million pixels", 131indicates that this is the second dual-CCD model with this resolution,
and GE stands for "GigE Vision" interface.

*1) : AD-131GE uses prism optics. For optimal performance, C-mount lenses should be designed for
interfacing to a 3CCD camera. Rear protrusion of the C-mount lens must be less than 4mm
to avoid damage to the prism.
*2) : When an RJ-45 cable with thumbscrews is connected to the camera, please do not excessively
tighten screws by using a screw driver. The RJ-45 receptacle on the camera might be
damaged. For security, the strength to tighten screws is less than 0.147 Newton meter (Nm).
Tightening by hand is sufficient in order to achieve this.

6. System Configuration
6.1. System connection
When the AD-131GE is connected to a PC, there are two connection methods.
Method one is to use dual or quad input Network Interface Card (NIC) or two separate network
interface cards. The other way is to use a hub as shown below.
Note: Connect both GigE terminals to PC. High S/N and High Dynamic range modes use only one
terminal but the other is also used for communication.
Fig.6 System configuration
It should be noted that the hub being used should comply with Gigabit Ethernet.
When JAI SDK control tool is started, AD-131GE is recognized as two cameras. #0 represents the
Bayer color imager #0 and #1 represents the Bayer color imager #1.
Each imager can be handled as an independent camera.
Two image sensors can be operated either in SYNC mode or ASYNC mode.
For the details, please refer to the following chapters 6.2 and 6.3..
6.2. RJ-45 outputs
The AD-131GE has two RJ-45 connectors for two monochrome sensors, #0 output and #1 output.
The output for the sensor #0 is through GigE-1 and sensor #1 output is through GigE-2. These
two outputs can be set at synchronous (SYNC) or asynchronous (ASYNC) in Sync Mode feature.

AD-131GE has two sensors inside and these two sensors can be synchronized or operated
independently. This mode selection is activated by Sync mode feature.
Factory default setting is Async.

7. Inputs and outputs interface
7.1. Overview
All input and output signals pass through the GPIO (General Purpose Input and Output) module.
The GPIO module consists of a Look-Up Table (LUT Cross-Point Switch), 2 Pulse Generators
and a 12-bit counter. In the LUT, the relationship between inputs, counters and outputs is
governed by internal register set-up.
Fig. 9 Cross point switch
7.1.1 LUT (Cross Point Switch)
The LUT works as a cross-point switch which allows connecting inputs and outputs freely. The
signals LVAL_IN, DVAL_IN, FVAL_IN and EEN_IN all originate from the camera timing circuit.
On this diagram, Frame Start Triggeris used for exposure and Transfer Start Triggeris used
for Delayed Readout. The Time Stamp Reset signal can reset the time stamp specified in GigE
Vision Format. This signal can be used when time stamps from several cameras connected are

range 1 through 4096, allowing a wide range of clock frequencies to be programmed. Setting
value 0 is bypass, setting value 1 is 1/2 dividing, and setting value 4095 is 1/4096 dividing. As
the pixel clocks for the AD-131GE are 51.324 MHz, the output frequency is varied from 51.324
MHz to 12.53 KHz.
7.1.3 Pulse Generators (0 to 3)
Each pulse generator consists of a 20-bit counter. The behavior of these signals is defined by
their pulse width, start point and end point.
The pulse generator signals can be set in either triggered or periodic mode (Free Run).
In triggered mode, the pulse is triggered by the rising edge, falling edge, high level or low level
of the input signal. In periodic mode, the trigger continuously generates a signal that is based
on the configured pulse width, starting point and end point.
7.2. Opto-isolated Inputs/Outputs
The control interface of the C3 GigE Vision camera series has opto-isolated inputs and outputs,
providing galvanic separation between the cameras inputs/outputs and peripheral equipment.
In addition to galvanic separation, the opto-isolated inputs and outputs can cope with a wide
range of voltages; the voltage range for inputs is +3.3V to +24V DC whereas outputs will handle
+5V to +24V DC.

7.3. Input and output circuits
In the following schematic diagrams, the input and output circuits for video and timing signals
are shown.
7.3.1 Iris Video output
This signal can be used for lens iris control in Continuous
mode. The signal is taken from the CCD sensor output
through the process circuit but as the reverse
compensation is applied, the signal is not influenced by
the gain settings. The video output is without sync. The
signal is 0.7 V p-p from 75 without termination.
This signal is taken from sensor 1 but it can be changed
by the register. In order to get this signal, DIP switch
DSW700 should be changed. Refer to 5.4.3.
Fig.14 Iris video output
7.3.1.1 Iris Video input and output
The lens-iris video output level at pin 4 of the 12-pin Hirose
connector is 700 mV for 100% video output level. The iris
video signal is taken after the gain circuit. However,
negative compensation is applied to the iris circuit, thus the
gain setting has no influence for controlling auto iris lenses.
It is without sync.
Fig.15 Iris Video output
7.3.1.2 Iris video output select
As the factory default setting, the signal from AD-131GE #0 is used for iris control. The setting
can be changed in the following screen. This screen is effective if AD-131GE #0 is selected.
