1 Hardware Introduction
1.1 Product Description
The JAI TM-6740GE is a dual-tap output, high-speed progressive scan CCD camera. The interline-type CCD
permits full vertical and horizontal resolution of very high speed shutter images and applications. The
electronic shutter, which has speeds to 1/64,000 sec., can be reset asynchronously by external pulse control.
The frame rate for a full image is 200 fps, with partial scan mode of up to 3205 fps. A 4:3 ratio imager format
with uniform square pixels provides superior image definition in any orientation. On-chip micro lenses provide
increased sensitivity.
The TM-6740GE has a full dynamic range control function, which can be set via software selectable look-up
table (LUT) knee slopes to convert 10-bit input to 8-bit output, thereby optimizing the CCD’s full dynamic
range in the normal output signal range. As a dual-tap output camera, the TM-6740GE has semi-auto-gain
balancing functions.
Applications for the TM-6740GE include machine vision, medical imaging, intelligent transportation systems,
high-definition graphics, on-line inspection, gauging, character reading, archiving, and high security
surveillance.
The TM-6740GE series consists of the TM-6740GE (monochrome) and the TMC-6740GE (color), as well as the
RoHS-compliant versions RM-6740GE and RMC-6740GE. Unless otherwise noted, all information contained in this
manual is relevant to all 6740GE models.

1.2 Features
•Miniature size and light weight
The printed circuit boards in the TM-6740GE have been arranged to create modular electronics, giving the
camera flexibility. In addition, the use of miniature solid-state components results in a compact,
lightweight camera that is 50.8mm x 50.8mm x 84.3mm in dimensions, and weighs only 194 grams.
•Imager
The TM-6740GE uses a dual-tap progressive scan interline transfer CCD that has the following features:
− Resolution of 640 x 480 active pixels for excellent image quality.
− 7.4 x 7.4 μm square pixels for precise dimensional measurement.
− High-speed electronic shutter capability for high dynamic resolution of moving objects
that eliminates the need for a mechanical shutter.
− Progressive scan CCD eliminates interlace deterioration of image and increases ease of
computer interface.
− High sensitivity and low noise at fast scanning. The CCD has an excellent S/N ratio at the
default setting that is greater than 50dB.
− The CCD has built-in microlenses for increased quantum efficiency.

TM-6740GE Series
•Electronic shutter
The TM-6740GE has a substrate drain-type shutter mechanism which provides superb pictures at various
speeds without smearing.
•Asynchronous reset
The TM-6740GE captures async reset images and provides single-shot video output with single FDV. This
makes it simpler for an ordinary frame grabber to capture the async reset images. The TM-6740GE’s
asynchronous reset is flexible and accepts external horizontal drive (HD) for phase locking. When the VINIT
(5V) pulse is applied to CC1, it resets the camera's scanning and purging of the CCD.
The TM-6740GE has four modes to control the asynchronous reset and shutter speed:
− Async, no shutter. The video signal and FDV are reset by external VINIT.
− Async Programmable shutter. The shutter speed control depends on the number of
horizontal lines defined by the user.
− Internal shutter speed control. The speed control varies from 1/200 to 1/64,000 sec. The
video signal and FDV starts with internal V reset timing related to shutter speed.
− External VINIT with pulse width. The duration between pulse edges controls the shutter
speed externally.
•Output
The TM-6740GE has a 10-bit/8-bit Gigabit Ethernet output. The analog output is 714 mVp-p composite
video (75 ohms) on all models.
•Dual-channel auto black level balancing and semi-auto gain balancing
The TM-6740GE, as a dual-tap output camera, has auto black level balancing and semi-auto gain balancing
functions.
•Integration
The TM-6740GE is capable of capturing high-resolution integration images. Its CCD imager can be exposed
for longer than the normal scan timing of 1/200 sec. This integration feature provides extra sensitivity for
applications in dark environments. The progressive scan imager permits a full frame of resolution in noninterlace format. Integration is achieved by applying INTEG signal to CC2 control of Gigabit Ethernet or by
feeding VINIT pulse width control up to 1 sec of the pulse width in async pulse width control mode for the
frames to be integrated.

2.2 Camera Setup
2.2.1 Heat Dissipation
The TM-6740GE is a compact 640 by 480 camera. Since all the electronics have been packed in a compact
package, the outer case of the camera can become hot due to heat dissipation. For optimal performance, JAI
recommends using a cooling fan to set up a positive air flow around the camera and following the precautions
below.
•Mount the camera on a large heat sink (camera bracket) made out of heat-conductive material like
aluminum.
•Make sure the flow of heat from the camera case to the bracket is not blocked by a non-conductive
material like plastic. • Make sure the camera has enough open space around it to facilitate the free flow of
air.

PD-12UEP PD-12UU with 12-pin connector
If you are providing power through the 12-pin connector, the PD-12P, PD-12UEP and PD-12UUP power supplies
are available with the 12-pin mating connector already attached to the leads from the power supply. You can
connect the PD-12UU and PD-12UE power supplies to the JAI power cable either directly or using a terminal
strip.
When wiring the PD-12UU and PD-12UE power supplies directly, note the following:
• Twist the lead ends together and tin-solder them for strength and electrical continuity.
• Use shrink tubing or a similar insulator to prevent exposed leads from touching and shorting.
• The +12V lead is marked with a red stripe or white lettering; be sure not to reverse the leads.
• All connections must be properly insulated to prevent shorting.
2.2.3.2 JAI Power Cables
If you are using JAI power cables such as the 12P-02S, refer to Figure 3 which shows the cable pin-out diagram

2.2.3.3 Building Your Own Power Cable
Refer to the 12-pin connector pin-out in Table 1 on page 12. Connect the Ground lead to pin #1, and the +12V
DC lead to pin #2 of the 12-pin connector. Power must be DC-regulated, and of sufficient current to properly
power the camera.
2.2.3.4 Attaching the Power Cable to the Connector
The 12-pin connector is keyed and will only fit in one orientation. To properly attach the power cable to the
camera connector, use the following steps:
1. Rotate the connector while applying slight pressure until the keyways line up.
2. Press the connector into place until firmly seated.
3. Plug the power cord into the 100V AC socket. This powers up the camera.
Note: If using a power supply other than the standard PD-12U Series from JAI, certain characteristics are
required of the power supply and the wiring in order to properly power the camera. The camera requires
12V immediately upon start-up; no slow ramps. Once power is applied, the po wer supply must be able to
support a 2A to 2.5A in-rush current for approximately 200µs to prevent the voltage at the camera from
dropping below the 10.8V minimum required. Dropping below this will result in the camera’s inter nal
power supply lowering its impedance in an attempt to draw more current. Since no more current will be
available, the voltage at the camera will drop instead. This will result in a steady state hang-up which
will damage the camera’s power supply and cause the camera to cease operating or to operate in an
unstable manner.
2.2.4 Attaching the Camera Lens
The TM-6740GE camera accepts 1/3" or larger format size C-mount lenses. To attach the C-mount lens to the
camera, carefully engage the threads and rotate the lens clockwise until it firmly seats on the mounting ring.
Do not force the lens if it does not seat properly.
Note: Some lenses with extremely long flangebacks may exceed the mounting depth of the camera.
C-mount to F-mount and C-mount to K-mount adapters are available for larger format lenses (35mm). Check
with local photography dealers for these lens adapters.
2.2.5 Adjustable Back-Focus
Before cameras are shipped, back focus is carefully set using a collimator, oscilloscope and other specialized
equipment. While the factory-set focus serves well in most cases, an adjustable back focus makes it possible to
improve image sharpness when using lower-cost zoom lenses, custom optics, or in unusual parameters.
There should be an obvious need to refocus the lens before attempting to change the back focus. This is a very
exacting task. Some cameras have been returned to the factory to reset the back focus after failed attempts to
change the focus by customers. It might be wise to label cameras whose back focus was adjusted
The camera must be connected to a monitor before attempting to adjust the back focus.
1. To back focus the camera, first attach a C-mount lens in the mount. Be certain that the lens is properly
seated.
2. Next set the lens focus to infinity (if the lens is a manual iris, set the iris to a high f number while still
retaining a well illuminated image).
3. Loosen the three miniature hex set-screws (use a 0.9 mm hex wrench) that lock the focus ring in place
(two screws for a CS-mount). Slowly turn the lens and focus ring assembly back and forth until you obtain
the best image of the desired object. This sets the back focus. Once the best image is obtained, tighten
the focus ring set-screws until they are snug. Do not over-tighten the screws. Note: Mini-bayonet cameras
adapted to C-mount do not have the back focus feature.

3 Operation
3.1 Progressive Scanning
The TM-6740GE uses a state-of-the-art progressive scanning interline transfer CCD which scans all lines
sequentially from top to bottom at one frame rate. Like a non-interlace computer screen, it generates a stable,
crisp image without alternating lines and provides full vertical TV resolution of 480 lines. Due to the TM6740GE’s extremely high frame rate, however, it will not synchronize to most monitors.
The interline transfer architecture is also important to generate simultaneous shuttering. This is different from
full frame transfer architecture, which requires a mechanical shutter or strobe light in order to freeze the
object motion.
The TM-6740GE outputs the progressive scanned image with an electronic shutter in thirty-six different
formats. See Table 2 on page 17 for more information.
Progressive scanning digital and analog output
The CCD signal goes through A/D converters 10-bit in, 10-bit/8-bit out. The digital output is available via the
Gigabit Ethernet connector.
The analog output is the same as 75 ohms, 714mV format available from BNC and 12-pin connector. Full
Progressive Scan
Normal scanning mode for the TM-6740GE is 640 x 480 pixels. The standard speed with dual-channel output is
200 frame/sec at the pixel clock rate of 40 MHz. The progressive scan reads every line from top to bottom and
all lines are exposed with a single electronic shutter.

3.2 Bayer Color Filter (Color Versions)
JAI AccuPiXEL series color cameras are high-resolution, high-speed progressive scan CCD cameras. The interline
transfer, progressive scan CCD permits full vertical and horizontal resolution of images acquired at very high
shutter speeds. Uniform square pixels provide superior image definition in any orientation. On-chip micro
lenses mean increased sensitivity.
3.2.1 Color Filter Array
JAI AccuPiXEL cameras use Bayer CFA (color filter array) as their standard primary color filter. This filter
provides the most popular color interpolation supported by numerous software suppliers.
The digital format allows the camera to output accurate pixel data, including the color information. When the
data is stored in the frame buffer of a frame grabber or computer, the color information is easily manipulated
to restore the original color images. Because the color filter array contains only a single R, G or B color in each
pixel, the restored image has to fill in the missing color information in each pixel location. The software uses
neighboring pixel information to “guess” the missing colors to make smooth, clear images. This is called “color
interpolation.” Today's high-speed computers allow such color interpolation to be done almost in real time.
Because these cameras do not contain internal color processing circuitry, they are smaller and less expensive
than full-function color cameras.

3.2.2 Bayer Color Filter Array (CFA)
The Bayer CFA is an R, G, B primary color filter array. This is the most widely accepted CFA for the single-chip
CCD progressive scan format. This type of array layout has a specific order for each color’s pixels. Since the
human eye’s resolution and color recognition are highest at green, the CFA contains two greens per each red
and blue.
It is critical for the frame grabber and color interpolation to know where the individual color pixels exist
relative to sync (LDV and FDV) timing.
This requirement makes digital output the preferred choice, because the timing relationships are very
accurate.
18 Operation
Page 19
TM-6740GE
Series
3.2.3 Starting Pixel Configuration
All manufacturers produce identical Bayer CFAs, but there are slight differences between the CCDs produced by
different manufacturers. The first line is generally R and G. The camera timing can be adjusted to start with
either G or R by skipping the very first pixel in each line. The majority of color interpolation software can
select between a variety of pixel relations, such as R/G start or G/R start, as well as G/B start and B/G start.
Once the correct scanning is configured, the rest of the interpolation will be exactly the same. Please contact
JAI for further information regarding CCD manufacturers.
Figure 7. Example of Color CCD CFA Pattern
3.2.4 Sync and Data
The individual color data is exactly the same as the pixel data. This means that the timing relationships of the
color cameras are also the same as of the B/W cameras.
For a detailed timing chart, please refer to each B/W camera’s data sheet and manual.
The following diagram is an example of the TMC-6740GE default mode. FDV and LDV are used internally for the
GigE interface.
Operation 19
Page 20
TM-6740GE Series
Figure 8. Example of TMC-6740GE in Default Mode.
It is important to meet the exact starting pixel at the line, and the starting line in frame. If the starting pixel
or line is shifted due to the image capture configuration, then the interpolation software can be adjusted for
the correct starting point.
3.2.5 Camera Functions
AccuPiXEL color cameras perform all functions the same way as B/W cameras. However, because of color
characteristics, the LUT (Look-up Table) is different. The LUT is a powerful tool to adjust the dynamic range,
as well as the color dynamic range. Since human color perception is non-linear, LUT selection can help
optimize color contrast by selecting the LUT value. Gamma 0.45 is logarithmic and is close to human
perception.
When LUT is selected, black-level adjustment must be more accurate than for B/W cameras.
3.2.6 Interpolation Software
The color interpolation can be performed in the frame grabber or by using the host computer’s CPU. Most
major frame grabbers with processing capability provide tools for color interpolation. Software vision packages
also provide color interpolation capability, but speed and performance may be determined by the PC’s
resources and by the complexity of the interpolation routine.
3.2.7 Color Interpolation
The Bayer pattern color filter array (CFA) consists of R, G, and B primary colors. Each pixel represents one of
three colors. In order to display or print color images, the signal has to be converted to RGB output, which has
three independent channels (outputs) and sync signals.
Color interpolation software or firmware performs the color preprocessing by
filling the missing color pixels with neighboring pixels. It then separates the
stream of data, (8-bit or 10-bit) into 3 (RGB) data (8-bit x 3) and adds the
color matrix to adjust and balance each of the R,G, and B channels (white
balance or color balance).
The image quality depends on the camera’s own pixel data (including pixel
data independency from neighboring pixels, noise and color filter), and
interpolation of the software algorithm such as 3 x 3 interpolation, 2 x 2
interpolation, color matrix, white balance capability, etc.
20 Operation
Page 21
TM-6740GE
Series
All AccuPiXEL color cameras are carefully designed for maximum color performance. JAI strongly suggests that
you use digital output for the best performance.
Some software is used on board (FPGA or DSP) to perform the interpolation. Other software simply uses the
host computer’s memory and CPU. The processing speed may vary depending on the architecture and speed of
the computer.
3.3 Electronic Shutter
The TM-6740GE has a substrate drain-type shutter mechanism which provides a superb picture at various speeds
without smearing. A built-in fixed shutter speed control selects the electronic shutter rate from 1/250 to
1/64,000.

With VINIT high (CC1), the CCD keeps discharging. With an active low pulse to VINIT, the camera resets and
purges the charge momentarily. Then it starts integrating for the period of shutter control set by either an
external pulse width or internal shutter control. Progressive scanning in the TM-6740GE permits a full 480 lines
of vertical resolution, as compared to an interlaced CCD camera which captures only half the vertical lines per
shutter.

The CCD imager of the TM-6740GE can be exposed for longer than the normal scan timing of 1/200 sec. This
integration feature provides extra sensitivity for dark-environment applications. The progressive scan imager
permits a full frame of resolution in non-interlace format. Integration is achieved by controlling CC2 Camera
Control line through the Gigabit Ethernet cable to low (GND) or providing pulse-width control up to 1 sec.
Please refer to Figure 3, “12P-02S Interface Cable (optional),” on page 13 for pin-out information on the 12-pin
connector.
3.5 External Sync
The TM-6740GE accepts an external sync of standard HD and VD on CC3 and CC4 of the 12pin connector for
general locking to an external source. The frequency requirement is shown in Table 2 on page 17. The
tolerance is ±2% horizontal frequency.
3.6 Asynchronous Reset
The TM-6740GE camera includes four modes to control the asynchronous reset and shutter speed:
• Async No Shutter (recommended for strobe applications)
• Async Programmable Shutter
• External VINIT with Pulse Width (No-Delay Shutter) and ROI (read-out-inhibit)
Operation 21
Page 22
TM-6740GE Series
3.6.1 Async No Shutter
Async No Shutter allows for strobe and back-to-back strobing (strobing both before the transfer gate and right
after) applications as shown in Figure 9. This mode is meant to be used in a dark environment in conjunction
with a strobe light.
Figure 9. Async No Shutter
Vinit trigger starts the first exposure period within one line (1H = 10 μsec.) and transfers the frame after a 43
μsec. exposure. After the first transfer, a new full frame exposure period (5msec.) begins. Please see Camera
Timing Charts below.
3.6.2 Async Programmable Shutter
22 Operation
Page 23
TM-6740GE
Series
The video signal starts with internal VINIT. When the external VINIT pulse is applied, internal VINIT is latched
to HD and the internal VINIT is delayed to set up the shutter speed period. The shutter speed is controllable by
the user via communication software. Video output timing starts right after the internal VINIT and single shots,
FDV is output at the internal VINIT timing.
3.6.3 External VINIT With Pulse Width (No-Delay Shutter) and ROI (Read-out Inhibit)
For multiple-camera applications such as 2D or 3D measurement and multi-angle inspection, simultaneous
image capturing at an exact shutter timing for all cameras is a critical requirement. The TM-6740’s
asynchronous pulse-width control mode provides no-delay shutter (Figure 10, “Pulse Width Control No-Delay
Shutter” on page 23) as standard. Regardless of the internal pulse timing, the camera discharges at the VINIT
leading edge and transfers charges at the trailing edge of the pulse. Even though each camera runs with slightly
different H and data clock timing, the image capturing is exactly simultaneous.
Figure 10. Pulse Width Control (No-Delay Shutter)
The TM-6740GE camera also has read-out-inhibit control (ROI) to control the vertical clock start (Pulse Width
Control mode). The ROI signal is fed in via the Integration Signal pin (External_INT_In). When ROI is low, Vclock is stopped and the transferred charges remain in the vertical shift registers, which work like CCD
memory. When the ROI is high, it clocks out the CCD data. This helps a single frame grabber process multiple
images in pipeline processing (sequential process).
Note: When the ROI function is not used, make sure that the INTEG/ROI input is kept logic high during Async.
Pulse Width control mode. This done via the Programmable Logic Controller (See IP Engine Examples
section 5.8.8).

3.6.4 Async Programmable Exposure Mode
Async Programmable exposure is determined by a shutter value entered from 0 to 2079. The shutter value
equals 1H (horizontal line time) or 10 μsec for each increment. The Async Programmable exposure timing
functions exactly the same as the internal shutter speed control. Async Programmable value is user controlled
via GigE camera acquisition software. The GUI interface that controls Async Direct Shutter exposure is
illustrated in Figure 12 below.

3.7 Dynamic Range Control
The typical interline transfer CCD has fixed noise levels based on dark current (thermal or KT noise), pattern
noise, and the operating clock speed. In general, the level of the 40 MHz pixel clock CCD at room temperature
is around 20 to 30 electrons. The maximum capacity of CCD charges is limited by the well capacity at
saturation. The range is limited by the structure and the pixel size.
The TM-6740GE uses a CCD with 7.4 μm x 7.4 μm pixels and a two-phase vertical shift register structure. The
well capacity is 20,000 electrons. The theoretical dynamic range is 20,000:30 = 666:1 (56 dB).
A typical CCD camera does not use the full dynamic range due to the nominal gain and the output specification
such as RS-170. The typical CCD camera’s gain is set between 16 and 22 dB and the RS-170 video level is 714
mV. Using 20 dB gain for the calculation, CCD output is limited to 714/10 = 71.4 mV. Since the CCD’s saturation
voltage is 400 mV to 500 mV, it uses less than 1/5 of the full dynamic range.
Machine vision and outdoor applications cannot afford to miss image information behind the saturation, which
is why the dynamic range adaptation is critical.
3.7.1 Programmable Look-Up Table (LUT) and Knee Control
The TM-6740GE has a built-in LUT (look-up table) for dynamic range control. At a specific gain setting, the
offset (minimum level.... dark point) and A/D reference top voltage (maximum level... saturation point) are
set to 10-bit A/D input so that the full dynamic range of the CCD is utilized at 10-bit references as the input
and the LUT output is converted into 8-bit to adjust the gamma correction. Notice that the LUT (look-up table)
is not available in the 10-bit grayscale mode.
The look-up table has two knee points (variable gamma selection) that allow the 10-bit input to be segmented
into three regions. The look-up table selection can be made by knee curve direct input.

The TM-6740GE series cameras are designed in accordance with the GigE Vision standard. Digital images are
transmitted over Cat5e or Cat6 Ethernet cables. All camera functions are also controlled via the GigE Vision
interface.
The camera can operate in continuous mode, providing an endless stream of images. For capturing individual
images, related to a specific event, the camera can also be triggered. For precise triggering, it is recommended
to use a hardware trigger applied to the Hirose 12-pin connector. It is also possible to initiate a software
trigger through the GigE Vision interface. However, when using software trigger, certain latency inherent to
the GigE interface must be anticipated. This latency, that manifests itself as jitter, greatly depends on the
general conditions and traffic on the GigE connection. The frame rate described in this manual is for the ideal
case and may deteriorate depending on conditions.
When using multiple cameras (going through a switch and/or a single path) or when operating in a system with
limited transmission bandwidth the Delayed Readout Mode and Inter-Packet Delay functions can be useful.
4.2 GigE Vision-Aware Software
A GigE Vision camera can be controlled by any software that understands the protocol. At JAI we provide the
JAI GigE Vision SDK and Control Tool to interface with our cameras. The remainder of the manual will show
screenshots of the JAI Control Tool but other 3rd party software will provide similar functionalities.
4.3 Recommended Network Configurations
Although the TM-6740GE series cameras conform to Gigabit Ethernet (IEEE 802.3) not all combinations of
network interface cards (NICs) and switches/routers are suitable for use with the GigE Vision compliant
camera.
4.3.1 Verified Network Interface Cards (NICs)
At the time of publishing this document these combinations have been verified:
NIC: Intel Pro/1000MT, Pro/1000GT, Pro/1000PT.
CPU: Intel Core 2 Duo 1.84Ghz.
Memory: 2 GB
Video Card: video card on PCI Express bus with at least 256MB of VRAM.
Functions such as screen saver and power save should not be used. Unnecessary applications such as Word,
Excel or others should not be used.
4.3.2 Video data rate (network bandwidth)
The video bit rate for TM-6740GE series cameras at the continuous mode is:
Packet data volume
(In case the Packet size is 4040)
511 Mbit/s @ Packet Size of 1428 Bytes
498 Mbit/s @ 4040PacketSize
Functions and Operations 35
Page 36
TM-6740GE Series
Note: The Mono10 and BayerGRI0 settings at full frame rate will exceed GigE bandwidth. It is recommended to
use Mono8, Mono10Packed, or BayerGR8 for max frame rate.
For TM-6740GE series cameras, the jumbo frame can be set at a maximum 16260 Bytes (Factory setting is 1428
Bytes). To set Jumbo Frames, refer to section 4.3.4.
To ensure the integrity of packets transmitted from the camera it is recommended that these simple guidelines
be followed:

4.3.7 Calculating and setting Inter-Packet Delay
When connecting several cameras to one network interface card via a switching hub, it is important to optimize
the Inter-Packet Delay of the cameras to avoid congestion in the switch. A sure sign of congestion is the loss of
packets.
Since increasing the inter-packet delay also adds overhead to the data transfer it is important to calculate the
optimal setting in order to make best use of the video bandwidth.
JAI Control Tool has a built in wizard for calculating Inter-Packet Delay. When the Inter-Packet Delay function
is activated, a button appears on the right hand side of the bar. Click the button to open the calculation wizard

5.3 Image Size Controls
These controls allow you to make adjustment to the image’s size, scan mode, and binning. Please see section
3.1 for a table of possible image sizes and modes.
Figure 15. ImageSizeControl category
SensorDigitizationTaps: the image sensor is read out via two channels. This feature is read only and shows that
the camera is always in DualTap mode.
WidthMax: shows the current valid maximum value for Width.
HeightMax: shows the current valid maximum value for Height.
Width: sets the width of the output image. When ScanMode is changed it is necessary to set this value to equal
to or less than WidthMax.
Height: sets the height of the output image. When ScanMode is changed it is necessary to set this value to
equal to or less than HeightMax.
OffsetX: specify the offset from the left edge of the image captured by the sensor to be sent out of the
camera. Width must be set lower than WidthMax before this value can be increased.
OffsetY: specify the offset from the top of the image captured by the sensor to be sent out of the camera.
Height must be set lower than HeightMax before this value can be increased.
Offset Example:
− ScanMode is set to B_640x160
− Width to 600 and Height to 100.
− OffsetX can have a range of 0 to 40. OffsetX is then set to 20.
− OffsetY can have a range to 0 to 80. OffsetY is then set to 35.
− The resulting image is of size 600x480 with the upper left pixel offset by 20 pixels
horizontally and 35 vertically

5.4 LUT (Look Up Table)
The camera’s LUT is used for dynamic range control when the camera is in 8-bit output mode (Mono8 or
BayerGR8). This allows for the full utilization of the image sensor’s 10-bit output as it is mapped to the 8-bit
output.
Figure 17. LookUp Table
LUTMode: controls which LUT table to use. There are 2 predefined tables and 1 user configurable table.
Available options:
− Linear: a linear mapping
− Gamma45: also known as Gamma 0.45.
− Knee: you can specify the curve by controlling two points.
KneeX1: controls the X value of first Knee point.
KneeY1: controls the Y value of first Knee point.
KneeX2: controls the X value of second Knee point. This value must be greater than KneeX1.
KneeY2: controls the Y value of second Knee point.
KneeSet: after you have changed the values of the knee points click KneeSet to apply the setting. The camera
will take a few seconds to calculate the LUT table. If image acquisition is taking place the image will black out
for about 1 second.
LUTInversion: invert the current LUT table. This creates the negative of image.

5.7 GigEVisionTransportLayer
More advanced controls for setting IP Address, GigE Vision Stream Channel settings, etc…
A complete explanation of GigE is out of the scope of this manual therefore the user should seek out various
online guides about: Persistent/Static IP, DHCP, LLA, IP Address, Subnet Mask, and networking.
5.7.1 Persistent IP
When powered up and connected to the network the camera will use the following sequence to obtain an IP
Address:
1. Persistent IP
2. DHCP: a DHCP server on the network will assign the camera an IP Address.
3. Link-Local Address (LLA): an IP Address in the 169.254.X.X ranged is assigned.
By default only DHCP and LLA are enabled. LLA will always be enabled. To disable DHCP mode set
GevCurrentIPConfigurationDHCP to false.
You can also assign a static IP Address to the camera so the camera will always boot up with this IP Address. To
do so follow these instructions:
1. Set Visibility to at least Expert.
2. Set GevCurrentIPConfigurationPersistenIP to True.
3. Set GevPersistentIPAddress to the IP Address of your choosing. (Ex: 169.254.0.11)
4. Set GevPersistentSubnetMask to the subnet mask of your choosing. (Ex: 255.255.0.0)
5. Set GevPersistentDefaultGateway to the IP Address of your gateway. (Ex: 0.0.0.0)

5.7.2 Stream Channel Packet Size
Images are sent via the StreamChannel in GigE Vision terminology. The camera is able to adjust the size of the
data packets sent on this channel. The minimum required value is 576. It is recommended that a value of 1428
is used. If setting to above 1428, the network to which the camera is connected must be able to support Jumbo
Packets. To change the stream channel packet size follow these instructions:
1. Stop image acquisition.
2. Switch Visibility to at least Expert.
3. Set GevSCPSPacketSize to a desired value.
GevHeartbeatTimeout: specifies the current heartbeat timeout in milliseconds. Available only in Guru visibility
mode. The host software must send at least one command to the camera during this period otherwise it looses
control of the camera. This is usually handled by the control tool.
5.8 IPEngine
The camera is sectioned into two logical modules: a camera head and the IPEngine. The camera head contains
the components to capture images, while the IPEngine takes care of interfacing to the outside world and
transmitting captured images. The IPEngine contains the Programmable Logic Controller (PLC) and the Grabber.
The Grabber is responsible for image transmission. All input and output signals pass through the Programmable
Logic Controller (PLC). The PLC contains a Signal Routing Block, Control Bits, and Lookup Table. The PLC also
contains 4 Pulse Generators and 1 general purpose counter. By GenICam naming convention the Pulse
Generators are called Timers. The Counter and Timers are controlled under the CountersAndTimersControls
category, and the other parts are controlled under the IPEngine category.

5.8.1 SignalRoutingBlock
The Signal Routing Block is a group of switches that lets you route signals to the PLC Lookup Table. There are a
total of 8 input lines, numbered from I0 to I7. Each input line can accept a number of different signals. The
input signals can be from the camera head, externally from the 12-Pin cable, or the PLC itself.
This table show possible signals each input line can accept (“(D)” specifies factory defaults):

5.8.2 ControlBits
There are 3 Control Bits: PLC_ctrl0, PLC_ctrl2, and PLC_ctrl3. Note that PLC_ctrl1 is not available. The control
bits can be used as software triggers by toggling between two states: True and False. True sets the signal High,
while False sets the signal to Low.
When a bit is toggled on the host software, a Write Register command is sent to the camera. The arrival time
of the packet depends on current network traffic therefore is varied. These are recommended for testing
purposes. For more precise trigger usage please use an external input trigger signal thru the 12-Pin connector.
For a constant periodic trigger signal please use the Pulse Generators (Timers).

5.8.6 Pulse Generators controls
The Pulse Generator lets you create a pulsed digital signal with a configurable frequency. They can be
configured to emit a continuous (periodic) pulse. One use of this feature is to create a periodic trigger signal.
The low section of the signal is called Delay, and the high is called Duration.
TimerSelector: chooses which Timer to configure.
TimerDelayRaw: configures the raw value of the low section of the output signal. The formula to calculate
actual time is:
Duration of Low (nsec) = (Granularity + 1) * (TimerDelayRaw +1) * 30
TimerDurationRaw: configures the raw value of the high section of the output signal. The formula to calculate
actual time is:
Duration of High (nsec) = (Granularity + 1) * TimerDurationRaw * 30
TimerFrequency: a read-only field that shows the frequency of the pulse in Hz.
TimerGranularityFactor: a multiplier value used to scale the Delay and the Duration in increments of 30 nsec.
TimerPeriod: shows the timer’s period in units of nsec.
TimerTriggerActivation: select the signal state of the TriggerSource to start the Timer.
− RisingEdge: starts when the trigger signal goes from Low to High
− LevelHigh: starts when the trigger signal is at the High state.
− FallingEdge: starts when the trigger signal goes from High to Low.
− AnyEdge: starts on any Falling or Rising Edge.
− LevelLow: starts when the trigger signal is at the Low state.
TimerTriggerSource: select the source of trigger to start the Timer.
− PLC_Q: the trigger source comes from the PLC Q output. Each Timer has their source from
GrbCh0AcqCfgMemoryWaterLevel: the camera has 16MB of memory for frame buffering. Water level setting
specifies how much of that memory to use with the AcquistionMode’s recording features. Once the buffer is full
no more images will be stored. Possible settings are:
− Level50: 50%
− Level75: 75%
− Level87Point5: 87.5%
− Level100: 100%
GrbCh0AcqCfgInvertPixelData: invert pixel data turning the image into a negative image.
GrbCh0TrigCfgFrameToSkip: set the number of images to discard for every one it keeps from the camera head.
