1.TM-1327GE Hardware
Operation Manual
1Hardware Introduction
1.1 Product Description
The JAI TM-1327GE is a 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 1/21,000 second, can be reset asynchronously by external pulse control. The frame rate for a full
image is 30 fps. Higher frame rates are possible via the user programmable partial scan mode with a user-
defined start line and scan height anywhere from 1 line to full frame (1040 lines). A 2:1 ratio imager format
with uniform square pixels provides superior image definition in any orientation.
The TM-1327GE has a full dynamic range control function, which can be set at externally 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.
Applications for the TM-1327GE include machine vision, medical imaging, intelligent transportation systems,
high-definition graphics, on-line inspection, gauging, character reading, archiving, and high security
surveillance.
The TM-1327GE series consists of the TM/RM-1327GE (monochrome) and the TMC/RMC-1327GE (color). Unless
otherwise noted, all information contained in this manual is relevant to all models.
1.2 Features
The TM-1327GE has the following features:
•Miniature size and light weight
The printed circuit boards in the TM-1327GE 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 51mm x 51mm x 85mm in dimensions, and weighs only 212 grams.
•Imager
The TM-1327GE uses a progressive scan interline transfer CCD that has the following features:
−Resolutionof1392 x 1040 active pixels for excellent image quality(2/3" optical format).
−6.45 x 6.45 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 greater than 52dB.
−The CCD has built-in micro-lenses for increased quantum efficiency

RM/TM-1327GE Series
10 Hardware Introduction
•Electronic shutter
The TM-1327GE has a substrate drain-type shutter mechanism which provides superb pictures at various speeds
without smearing.
•Asynchronous reset
The TM-1327GE captures asynchronous reset images and provides single-shot video output with single FDV. This
makes it simpler for an ordinary frame grabber to capture the asynchronous reset images. The TM-1327GE’s
asynchronous reset is flexible and accepts external horizontal drive (HD) for phase locking. When the VINIT (5V)
pulse is applied to pin 6 on the Hirose, or the PLC 12-pin connector, it resets the camera's scanning and purging
of the CCD.
The TM-1327GE has three 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
controlled through software commands.
−External VINIT with pulse width. The duration between pulse edges controls the shutter speed
externally.
•Output
The TM-1327GE has a 10-bit/8-bit Gigabit Ethernet output. The analog output is 714 mV p-p composite video
(75 ohms) on all models.
•Warranty

2Installation
The following instructions will help you to set up your camera quickly and easily. JAI suggests that you read
through these instructions first, before you unpack and set up your camera system.
2.1 Getting Started
2.1.1 Unpacking Instructions
JAI recommends that you save the original packing cartons for the cameras and accessories in case you need to
return or exchange an item.
We also recommend that you bench-test any equipment being sent to another location for field installation to
assure that everything is fully operational as a system.
2.1.2 Components
When you receive your TM-1327GE camera from JAI, the contents of the shipping box should include the
camera and a document download card. If any of these items are missing, contact your JAI representative
immediately. The document download card includes instructions and web locations for downloading the
datasheet, manual, and camera-control software. If you do not have Internet access, contact JAI to receive this
material on a CD-ROM.
2.1.3 Accessories and Options
The following additional accessories and options may be required for your application:
•PD-12U series power supply
•12P-02S power cable
•Cat5e or cat6 shielded Ethernet cable (not supplied by JAI)
•Tripod Mounting Kit: TP-20
(for dimensions go to: www.jai.com/EN/CameraSolutions/Products/Accessories/Pages/Home.aspx)
Check with your JAI representative before you install your camera to determine what you might need.
2.2 Camera Setup
2.2.1 Heat Dissipation
The TM-1327GE is a compact camera. Since all the electronics have been packed in a compact package, the
outer case of the camera can become hot because of 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 a 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.
2.2.2 Connector Pin Configurations
The TM-1327GE has a 12-pin Hirose connector for power input and signal integration as shown on the following
page.

Use at least cat5e UTP cables (cat6 cables are preferred). JAI recommends the use of shielded cables to reduce
emissions and for CE/FCC compliance. Double-shielded cables further reduce emissions.
2.2.3 Power Supplies and Power Cable Setup
2.2.3.1 Power Supplies
The TM-1327GE camera requires 12V DC power obtained through the 12-pin connector located on the rear
panel of the camera. JAI recommends the following 100-240V AC/12V DC 1.2A universal voltage power supplies:
PD-12UU PD-12UU no 12-pin connector US Plug
PD-12UUP PD-12UU with 12-pin connector US Plug
PD-12UE PD-12UU European Plug
PD-12EUP PD-12UU with 12-pin connector European Plug
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 using a terminal strip or directly.

When wiring the PD-12UU and PD-12UE power supplies directly, note the following:
•Twist the lead ends together and tin-solder 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.
•Make sure all connections are 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 the Figure 3 which shows the cable pin-out
diagram and pinouts. The color-coded leads use Gray for Ground and Yellow for +12V.
Figure 3. 12P-02S Interface Cable (optional)

1 Gray GND (Power Ground) 7 Black coax TTL IN (External_VD)
2 Yellow +12V DC (Power In) 8 White coax shield TTL OUT (STROBE)
3 Red coax shield GND(Analog Ground) 9 White coax shield TTL IN (External_HD)
4 Red coax Reserved 10 Brown Reserved
5 Orange coax shield GND(Digital Ground) 11 Blue Reserved
6 Orange coax TTL IN (External_Trigger) 12 Black coax Reserved
Note: Make sure that the unused leads are not touching and that there is no possibility that exposed wires
could cause the leads to short.
2.2.3.3 Building Your Own Power Cable
Refer to the 12-pin connector pin-out in Figure 1. 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 will power up the camera.

RM/TM-1327GE Series
14 Hardware Installation
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 power 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 internal
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-1327GE camera accepts 2/3” or larger format size C-mount lenses. To attach the C-mount lens11to 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.
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
1. The camera must be connected to a monitor before attempting to adjust the back focus.
2. To back focus the camera, first attach a C-mount lens in the mount. Be certain that the lens is properly
seated.
3. 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).
4. 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.

1C-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.

3Operation
3.1 Progressive Scanning
The TM-1327GE 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 1040 lines.
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-1327GE outputs the progressive scanned image with an electronic shutter in two different formats.
•Progressive scanning digital - The CCD signal goes through A/D converters 10-bit in, 10-bit/8-bit out. The
digital output is available using the Gigabit Ethernet connector.
•Analog output - The analog output is the same as 75 ohms, 714mV format available from BNC and 12-pin
connector. Analog video does not conform to the RS-170 standard and is not RS-170 compatible.
3.1.1 Programmable Scan Area
In User Programmable scan mode, users can specify both the start point of the active scan area and the total
active lines through the serial communication commands. The area selected by users is transferred out line by
line. The rest of the lines are dumped out using the fast dump function of the CCD. The frame rate in this mode
varies according to the selected active area (see Section 3.8).
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. The electronic shutter, which has speeds to 1/21,000 sec., can be reset asynchronously by
external pulse control. 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 colors in the missing pixel locations. 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.

RM/TM-1327GE Series
16 Operation
This requirement makes digital output the preferred choice, because the timing relationships are very
accurate.
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 pixels at 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.

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-1327GE default mode. FDV and LDV are used internally for the

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.
For a detailed timing chart, please refer to the standard AccuPiXEL camera data sheet, or contact JAI.
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.
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-1327GE has a substrate drain-type shutter mechanism which provides a superb picture at various speeds
without smearing. A built-in flexible shutter speed control selects the electronic shutter rate from 1/30 to
1/21,000.
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 permits a full 1040 lines of vertical
resolution, as compared to a conventional CCD camera which captures only half the vertical lines per shutter.
3.4 External Sync
The TM-1327GE accepts an external synchronization of standard HD and VD on CC3 and CC4 of the Gigabit
Ethernet connector for general locking to an external source. The tolerance is ±2% horizontal frequency.
3.5 Asynchronous Reset
The TM-1327GE camera includes the following 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)
3.5.1 Async No Shutter
Async No Shutter allows for the use of a strobe light and back-to-back strobing (strobing both before the
transfer gate and right after) applications as shown in Figure 7.

3.5.2 Async Programmable Shutter Speed Control
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. Video output timing starts right
after the internal VINIT and single shots, FDV is output at the internal VINIT timing. Shutter speed is
determined by a direct shutter value entered from1 to 1040 via control software. The shutter value equals 1.5H
(horizontal line time) or 47.6 μsec. for each increment.

3.5.3 External VINIT With Pulse Width (No-Delay Shutter)
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-1327’s
asynchronous pulse-width control mode provides no-delay shutter 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.

3.6 Programmable Look-Up Table (LUT) and Knee Control
The TM-1327GE 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.
