CM-140 GE / CB-140 GE

1. General

This manual covers the digital monochrome progressive scan camera CM-140GE and
color progressive scan camera CB-140GE

The CM-140GE/CB-140GE is a GigE Vision compliant camera, based on the CM-140MCL/CB­140MCL. Both the monochrome version CM-140GE and the color version CB-140GE provide a
frame rate of 31 frames/second at full resolution in continuous operation. Using vertical
binning (CM-140GE only) and partial scan provides higher frame rates.
The 1/2" CCD with square pixels offers 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 color version CB-140GE, based on CCD sensor with primary RGB Bayer mosaic filter,
outputs raw Bayer images. Host-based color interpolation is required to display or save color
images.

The CM-140GE/CB-140GE also complies with the GenICam standards, as it has in internal XML
file that is used to describe the functions/features of the camera. For further information on
GenICam please go to www.emva.org.

As an application programming interface, JAI provides an SDK (Software Development Kit).
This SDK includes software documentation, register information, code examples and objects
such as Transport Layer and Device Drivers (High Performance Filter Driver and Standard
Windows Stack). 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.

The CM-140GE and CB-140GE cameras also accept industrial RJ-45
connectors with thumbscrews. This assures that the connector does not
come undone in tough industrial environments.
Please contact the nearest JAI distributor for details on recommended
industrial RJ-45 connectors.

6. GPIO (General purpose inputs and outputs)

6.1. 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), 4 Pulse Generators and a 12-bit
counter. In the LUT, the relationship between inputs, counters and outputs is governed by internal
register set-up.

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

6.1.1. 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 reset the camera's time stamp function, also making it possible to
reset and synchronize the time stamp of multiple cameras.

CM-140 GE / CB-140 GE

6.1.2. 12-bit Counter

A 25MHz clock or the camera pixel clock (65MHz) 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.

6.1.3. 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, 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.

6.2. 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 below figure shows the functional principle (opto-coupler) of the opto-isolated inputs/outputs.

Although the CM-140GE and CB-140GE are digital cameras, the image is generated by an analog
component, the CCD sensor.
The table and diagram below show the relationship between the analog CCD output level and the
digital output.

The standard setting for 10-bit video level is 890 LSB. 200 mV CCD output level equals 100% video
output.

7.2. Bit Allocation (Pixel Format / Pixel Type) – CM-140GE (monochrome)

In the GigE Vision Interface, GVSP (GigE Vision Streaming Protocol) is used as an application layer
protocol relying on the UDP transport layer protocol. It allows an application to receive image data,
image information and other information from a device.
In the monochrome camera, CM-140GE, the following pixel types supported by GVSP are available.
With regard to the details of GVSP, please refer GigE Vision Specification available from AIA
(www.machinevisiononline.org).

7.3. Bit Allocation (Pixel Format / Pixel Type) – CB-140GE (Bayer mosaic color)

In the Bayer mosaic color camera, CB-140GE, the following pixel types supported by GVSP (GigE Vision
Streaming Protocol) are available.
