200 lines). Features include compact size, rugged construction, double speed scan, asynchronous reset
and electronic shutter, non-interlace 60Hz analog video (VGA), and partial scanning. The double speed
mode is standard, thus the images can be displayed on a standard VGA monitor.
Applications include high speed image capturing, machine vision, computer graphics, gauging,
avionics, microscopy, character and fine pattern recognition, document reading and high end
surveillance.
1.2 Features

•
Asynchronous reset
The TM-6703 resets with an external reset pulse (VINIT). This feature is especially important for
capturing moving objects at a precise location in the field of view, for applications such as a
conveyer belt process, fast event observation, and still picture capturing.
•
Integration
The TM-6703 is capable of capturing high resolution integration images. Integration can last from
1/60 sec. to several seconds.
•
VGA display output
The TM-6703’s VGA output scans out at 60Hz non-interlace. Because the double speed mode is
standard, images can be displayed on a standard VGA monitor. PULNiX PVM-1200 series
monitors or equivalent B/W multi-sync monitors can be used to display non-interlace images.
Please contact your PULNiX representative for display monitor information.
•
Sync input (external sync) or output (clock and sync) selection (optional, OP7-2))
Rear board jumpers enable sync input/output selection. When the jumpers are set to internal sync,
the camera accepts HD and VD sync and video output from pin #4 of the 12-pin connector. If the
jumpers are set to OP7-2, then HD, VD and clock output are provided for a frame grabber to take
the data.
•
“One shot sync” (optional, OP51-2)
The composite sync of the video output can be selectable with the rear panel jumper (resistor
location). Continuous V-sync mode outputs the V-sync at all times regardless of async reset or
normal rate V-sync during async mode stand-by. Async V-sync mode outputs the V-sync once only
at async reset (at Vinit trigger) and no V-sync during the stand-by period (H-sync only in video
composite sync) until the next Vinit comes in. These modes can be selected based on a frame
grabber’s sync capability for async reset.
•
Three-Year Warranty
The CCD solid state image sensor allows the camera to maintain a superior performance level
indefinitely while requiring virtually no maintenance. PULNiX backs all of the TM Series cameras
with a three-year warranty.
WARNING: Unscrewing the camera cover or opening the camera in any way
will void this warranty.

Note: The “K” series power supplies are designed primarily for OEM users who will be
mounting the power supply inside a protective enclosure. For use in exposed situations,
the DC-12N and PD-12 are recommended.
2.2.3 (d) Building Your Own Power Cables
If you are building your own power cables, consult the pin-out for the camera purchased and connect the
Ground and +12V power leads of the PC-12P power connector to Pin #1 and Pin #2, respectively
(power must be DC regulated, and of sufficient current to properly power the camera).
2.2.3 (e) Attaching the Power Cable to the Connector
The 12-pin connector is keyed and will only fit in one orientation. Rotate the connector while applying
slight pressure until the keyways line up. Press the connector into place until firmly seated.
The power cord may now be plugged into the 100V AC socket, and the camera powered up.
2.2.4 Attaching the Video Output
Most users utilize the BNC connector for video output from the camera. Connect the output from the
camera to the input of your monitor, VCR or switching device. The input of the monitor should be
balanced for 75Ωtermination. Standard RG-59 type coaxial cable should carry a full video signal for up
to 500 feet.
Users wishing to output the video and input the power and sync to a camera over a single cable can use
the PULNiX multi-conductor cables, such as the 12P-02, the KC-10, etc. The mini coaxial leads in
PULNiX multi-conductor cables are designed for short runs of no longer than 100 feet.
Note: Make sure that no extraneous wires are visible which could cause a short.
2.2.5 Attaching the Camera Lens
The TM-6703 camera accepts standard 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. Please note that some lenses with extremely long
flangebacks may exceed the mounting depth of the camera.
2.2.6 Back Focusing the Lens
To backfocus the TM-6703 camera, first attach a C-mount lens in the lens mount. Be sure that the lens is
properly mounted.
Set the lens focus to infinity (if the lens is a manual iris, set the iris to a high f-stop while still retaining a
well-illuminated image). Obtain the best focus possible at this setting, then loosen the two miniature hex
head set screws (hex socket size: 0.89mm) locking the focus ring in place. Now turn the entire lens and
focus ring assembly back and forth until the best image is obtained. Tighten the focus ring set screws.
Your backfocus is now set.

INSTALLATION
Page 8 TM-6703 Progressive Scan Double Speed Shutter Camera
2.2.7 Auto Iris Lens Setup
Auto-iris lenses with full video input (1 Vpp) can be used with the PULNiX TM-6703, although this
camera model does not come equipped with auto-iris output.
Note: Make sure that the power is removed from the camera before connecting or disconnecting
the auto-iris lens. There is a small chance that damage could occur to the auto-iris lens by
plugging or unplugging it while the camera is powered up.
To install the auto-iris lens in a PULNiX camera for which the auto-iris output is not supplied, wire the
signal (video) on the lens into the terminal 1 Vp to peak video output on the camera (pin 4 of 12 pin
connector).
Point the camera at a light area and then quickly towards a darker area. If everything is working
properly, the iris should adjust for the light change.
2.2.8 Non-Interlace Black & White Monitors
The PULNiX PVM-942 / 1242 non-interlace black and white monitor, or an equivalent model, can be
used to display the TM-6703’s various display modes. In standard operation, including RS-170
interlace, 60 Hz non-interlace, 30 Hz non-interlace and 120 Hz non-interlace (two-row scanning mode),
the display is normal. In the partial scanning mode, the vertical extends to fill the monitor screen and the
images will be distorted vertically.

OPERATION
TM-6703 Progressive Scan Double Speed Shutter Camera Page 9
3 OPERATION
3.1 Modes of Operation
The TM-6703 is designed to accommodate a high resolution, on-line inspection reset mechanism with
full frame shutter. It accepts external horizontal sync (HD, TTL Levels) to lock the camera and VINIT
pulse for resetting the camera asynchronously. The shutter speed can be controlled by either an external
double pulse, or by internal speed control by setting the 10-position shutter speed dial switch on the
back panel.
3.1.1 Asynchronous Reset Mode
For the asynchronous reset mode, select ASY on the back panel of the camera.
The TM-6703's asynchronous reset is flexible. External HD can be applied for phase locking if required.
Applying a VINIT pulse resets the camera's scanning and purging of the CCD. Do not supply VD if the
asynchronous reset is used. Instead, use HD to synchronize the camera to the external device.
When external VINIT is high (5V), the TM-6703 expects the async pulse input and the video output will
be black video. It resets at the negative going pulse edge and captures the frame regardless of the shutter
speed (fast or slow mode). The video output is kept disabled as the CCD is discharged continuously
during VINIT high. When the first VINIT pulse comes in, it resets the timing and outputs the image. If
the switch is set to NRM (normal mode), the video output will be real time with manual shutter.

3.1.2 Driving /VINIT
The TM-6703 VINIT input circuit equivalently has 10K ohm input resistance (Figure 4, “VINIT
(Vertical Initialization) Trigger Specifications,”on page 10). To drive this circuit, at least 0.5mA of
current is required to drive the camera.
Note: The VINIT signal must be a defined, clean pulse for the asynchronous reset function to
work properly. Some triggering systems (e.g., optical isolators, mechanical relays, noisy
electrical devices, etc.) have bounce or rapid transition between high and low states. It is
highly recommended that the input VINIT pulse be analyzed by test equipment to ensure
proper signal characteristics. If an unspecified signal is used, improper camera
performance may result.

3.1.3 Shutter Control Switch
The shutter control switch is located on the rear panel of the camera. The dial can be
set from 0 to 9. The settings are detailed below.
Mode 0: Normal Mode
Mode 1-4: Fast Mode
Mode 5-8: Slow Mode
Mode 9: Pulse Width Mode
Note: Manual shutter speeds lower than 1/1,000 (i.e., longer in duration) are not applicable for
partial scan due to the short frame rate.
3.1.3 (a) External Pulse Width Control Mode
To select the External Pulse Width Control mode, set the shutter speed dial switch to “9”. Apply a pulse
width control VINIT signal to the camera via an external event trigger. The internal reset pulse will be
latched to HD. At the 9th HDtiming from the external pulse leading edge (negative going edge), the
CCD discharge pulse will be generated to clear the images. The internal VDis generated at the
following edge (positive going edge) of the external pulse, and resets the internal timing, including the
video sync.
The shutter speed will be the same as the external pulse width, but the integration delays 9H from the
leading edge of the external pulse width. For the immediate reset option, please contact PULNiX.
One frame of video output will start from the rising edge of the pulse width control for progressive
format. The camera will output the same video from memory when VINIT is kept high (5V), and update
the image upon receiving the next pulse. At async mode, with external pulse input high, the video output
is disabled as the camera keeps discharging the CCD image and only will provide black video.

3.1.4 Progressive Scanning
The TM-6703 uses a state-of-the-art CCD called a “Progressive scanning interline transfer CCD”which
scans all lines sequentially from top to bottom at one frame rate (60 Hz). Like a non-interlace computer
screen, it generates a stable crisp image without alternating lines and provides full vertical TV
resolution of 484 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-6703 outputs the progressive scanned image with an electronic shutter in three different modes.
These modes are selected via the switches on the rear panel of the camera.
1. Progressive scanning double speed output (Normal mode. Select N, O)
On the rear panel of the camera, select NRM (normal mode), N and O. This produces straight
forward signal output equivalent to non-interlace VGA format (60Hz). Real-time double speed
CCD output is converted through normal analog video processing into 75Ω1Vp-p output format.
2. Progressive scanning 120Hz output (Rear switches: N, T)
This mode provides 120Hz scanning of the full field of view, but with only 242 lines of vertical
resolution. The CCD signals of each row combine to scan 242 lines; the frame speed therefore is
120Hz of non-interlace video. The async reset, electronic shutter and integration function work as
normal. The analog output is the same as 75Ω, 1Vp-p format at the 120Hz rate.
3. Partial scanning output (Rear switches: P, T for 100 lines; P, O for 200 lines)
By selecting 100 line partial scan (P, T), the TM-6703 outputs the central 100 lines of video. It
repeats the same lines at a rate of 200 frames/sec. with the fast dump blanking of unused lines. The
asynchronous reset and electronic shutter functions are maintained at each partial scan.
By selecting 200 line partial scan (P, O), the TM-6703 outputs the central 200 lines of video at a
rate of 125 frames/sec. The partial scan keeps the same resolution as full progressive scan, but with
a narrower field of view.

3.1.5 Option 7-2
In order to connect the TM-6703 camera to various frame grabbers, internal jumper settings allow the
TM-6703 to accept external HD and VD sync at double speed (fH = 31.468 KHz), or to output HD, VD
and pixel clock for variable scan frame grabbers. This option can be requested when ordering the TM-
6703.

3.1.6 V-Sync Output Selection for Async Mode (OP51-2)
At async image capturing, some frame grabbers cannot take the specific frame when continuous video
sync presents. The TM-6703 video output is normally composite sync with frame rate V-sync regardless
of the actual image or blank image.When it is asynchronously reset, the newly reset V-sync may be
random to normal sync rate and can be very close to the regular rate V-sync. This may be problematic to
the frame grabber in capturing the correct image.By selecting the rear plate board jumper, the V-sync
output occurs only at the async reset, and no V-sync occurs until the next Vinit (async trigger) comes in.
The frame grabber can then look for this V-sync and capture the correct timing.
