1. General
This manual covers the digital monochrome progressive scan camera CM-140GE/CM140GE-RA and color progressive scan camera CB-140GE/CB-030GE-RA
The CM-140GE/CM-140GE-RA/CB-140GE/CB-140GE-RA /CM-140GE-UV is a GigE Vision compliant
camera. Both the monochrome version CM-140GE/CM-140GE-RA and the color version CB140GE/CM-140GE-RA provide a frame rate of 31 frames/second at full resolution in continuous
operation. Using vertical binning (CM-140GE/CM-140GE-RA 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/CB-140GE-RA, 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-UV employs UV sensitive sensor for covering UV wave length area.
The CM-140GE/CM-140GE-RA/CB-140GE/CB-140GE-RA/CM-140GE-UV 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 GigE®Vision standard, please
go to www.machinevisiononline.org and about GenICamTM, please go to www.emva.org.
As an application programming interface, JAI provides an SDK (Software Development Kit).
This SDK includes GigEVision 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

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.

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 complied with 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:
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 to reset the camera's time stamp function, also making it
possible to reset and synchronize the time stamp of multiple cameras.
CM-140 GE / -RA/-UV / CB-140GE/-RA
- 11 -
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. Setting Value 0 is bypass, setting value 1 is 1/2 dividing and setting value 4095
is 1/4096 dividing.
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 figure below shows the functional principle (opto-coupler) of the opto-isolated inputs/outputs.

6.4.3. Pulse generators (20 bit x 4)
There are 4 pulse generators (designated 0 through 3) that can be used to create various timing
scenarios by programming start point, endpoint, length and repeats.
The following example shows the FVAL input to pulse generator. The pulse generator creates the
pulse using FVAL and the pulse is output through GPIO PORT 1.

Pulse Generator Setting Example
Fig 9. Pulse generator setting example
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, the pulse having 100 x 1/25000 = 4ms width is created.
If the HIGH duration needs to be delayed against incoming trigger, the start point should be set at
“N“. The delay value is N x (1/ 25000).
In the above example, N is “0” which is no delay.
The length, in this case, is 102 clocks.

7.1. Digital Video Output (Bit Allocation)
Although the CM-140GE/CM-140GE-RA and CB-140GE/CB-140GE-RA 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.

7.2. Bit Allocation (Pixel Format / Pixel Type) – CM-140GE/-RA (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/CM-140GE-RA, the following pixel types supported by GVSP
are available.
With regard to the details of GVSP, please refer to GigE Vision Specification available from AIA
(www.machinevisiononline.org).
