JAI GigE Vision® Camera operation manuals

To understand and operate this JAI GigE Vision® camera properly, JAI provides the following manuals.

User’s manual (this booklet) Describes functions and operation of the hardware JAI SDK & Control Tool User Guide Describes functions and operation of the Control Tool JAI SDK Getting Started Guide Describes the network interface

User’s manual is available at www.jai.com JAI SDK & Control Tool User Guide and JAI SDK Getting Started Guide are provided with the JAI SDK which is available at www.jai.com.

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.

Camera Operation

1. General

The AT-140GE is a digital 3CCD progressive scan RGB color camera. It employs three 1/2-inch 1392 (h) x 1040 (v), 1.45 Megapixel CCDs and runs at 20 frames per second in full resolution mode. The AT-140GE has a GigE Vision interface and its output can be either 24-bit or 32-bit RGB. JAI developed a new 1/2-inch compact F4.0 prism optical system and in combination with a linear color matrix, the AT-140GE provides a higher fidelity of color reproduction. The AT-140GE also incorporates a dynamic shading circuit, gamma correction circuit and knee correction circuit to provide high picture quality. Functions like partial scanning and vertical binning allow higher frame rates.

6. Input and output circuits

This chapter introduces the basic diagram and bit allocation of digital output.

6.1. Iris video output

This signal can be used for lens iris control In Continuous and RCT modes. The signal is NUM luminance signal and passes through the gain circuit. However, due to reversed compensation applied, the gain settings do not influence this signal. The iris video output is 0.7 V p-p from 75  and without sync.

Fig. 9 Iris video output.

6.2. Trigger input

The trigger input is on pin #10 on the 12-pin connector or pin#3 on the D-sub 9-pin connector. The input is AC coupled. To allow a long pulse width, the input circuit is a flipflop, which is toggled by the negative or positive differentiated spikes caused by the falling or rising trigger edges. The trigger polarity can be changed. Trigger input level is 4 V 2 V. It can be terminated by SW600: ON for 75. OFF for TTL(Factory default).

Fig.10 Trigger input.

6.3. XEEN output

XEEN is found on pin #4 or #8 on D-sub 9-pin connector. The output circuit is 75  complementary emitter followers. Output level 3 V from 75. (No termination). When the open collector is used, the maximum current is 120mA. However, if a current of more than 50mA is flowed, it is necessary to use bigger diameter wires for connecting pin#8 and

9. In case of narrower wires, due to its resistance, it may not work properly.

This output can be changed to Open collector signal by SW100. EEN is found in OPT out in 12-pin connector.

7. GPIO (General purpose inputs and outputs)

In chapter 7, there are some examples of settings. the values shown in these examples may need to be adjusted to fit the pixel clock specifications of this particular model.

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.

On the above block diagram, Trigger 0 is used for Exposure and Trigger 1 is used for Delayed Readout. The Time Stamp Reset can reset the time stamp in compliance with the GigE Vision standard. This is used for having the same time stamp in case of using multiple cameras.

The blocks shown in the above diagram have the following functionality:

7.1.1 LUT (Look Up Table)

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. Trigger 0 is connected to the camera's timing circuit and is used for initiating triggered exposure. Trigger 1 is used for Delayed Readout mode. The Time Stamp Reset signal is used to reset the camera's time stamp function, also making it possible to reset and synchronize the time stamp of multiple cameras.

- 15 -

AT-140GE

7.1.2 12-bit Counter

The camera pixel clock (42.954 MHz) can be used as a source. The counter has a “Divide by N”, where N has the 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.

7.1.3 Pulse Generators (0 to 1)

Each pulse generator consists of a 20-bit counter. The behavior of these signals is defined by their pulse width, start point, end point and number of repetitions. The pulse generator signals can be set in either triggered or periodic mode. 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. The figure below shows the functional principle (opto-coupler) of the opto-isolated inputs/outputs.

Pulse Generator Setting Example

7.4.3 Pulse generators (20-bit x 2)

There are 2 pulse generators (designated 0 through 1) that can be used to create various timing scenarios by programming start point, endpoint, length and repeats.

An example of settings

The following example shows the FVAL input to a pulse generator. The pulse generator creates the pulse using FVAL and the pulse is output through GPIO PORT 1.

The created pulse rises up at the start point and falls down at the end point, as shown above. Accordingly, the High duration is (End point – Start point) clocks x (1/Pulse gen. frequency).

In the above example, the original oscillation uses pixel clock (60 MHz) and the pixel clock is divided by 2400. A pulse frequency of the generator is 25 KHz (60000000/2400). As the start point is 0 and the end point is 99, a pulse having a width of 100 x 1/25000 = 4ms is created.

If the High duration needs to be delayed against an incoming trigger, the start point should be set at “N”. The delay value is N x (1/ 25000). In the above example, the N is “0” which is no delay. The length, in this case, is 102 clocks.

These settings can be achieved by using the JAI Control Tool which is part of the JAI SDK.
