3610 CAMERA
TECHNICAL REFERENCE
1.0 GENERAL DESCRIPTION
This introduction briey describes overall
characteristics of the Camera (gure 1) related to
its installation and operation.
1.1 Electrical Characteristics
The 3610 Series provides a small, light-
weight, highly sensitive machine vision CCD
Camera with all electrical connections via a single
rear panel connector.
Setup and control settings are implemented
by a graphical user interface (GUI) communicat-
ing through an RS-232C serial interface with the
Camera.
The Camera operates in either NTSC or PAL
format depending on the model. This Camera op-
erates at an internal clock rate of 28.63636 MHz
(NTSC) or 28.375 MHz (PAL). Table 1 lists speci-
cations for this 3610 Camera.
Table 2 is a list of major features of the Cam-
era — primarily those associated with the GUI.
The Camera is available in two different
operating power congurations: 5 V dc and 12 V
dc. Only manual iris lenses can be used with the 5
V dc Camera. The 12 V dc Cameras are available
in three congurations: (1) an auto iris version
(2) a dc iris version or (3) a freeze frame version
— which requires the use of a manual iris lens.
Manual iris versions of the camera can be
optioned for horizontal and vertical drive inputs If
these inputs are not used the camera operates in
standard crystal sync reference mode.
1.1.1 Sensor Characteristics
Figure 2 shows the relative response charac-
teristic of the three sensor sizes available for this
camera. These characteristic curves apply to both
NTSC and PAL sensors. The curves show Cyan,
Green, Yellow and Magenta responses.
These graphs exclude both the lens charac-
teristics and the light source characteristics.
Note however that the IR cut lter shown in
gure 3 will modify the overall response of the
Camera to light. This low pass lter starts block-
ing light above about 500 nanometers and at 600
nm passes only about 50 percent. Rolling off the
response at these longer wavelengths minimizes
the effect of infrared on the color response of the
Camera.
1.2 Mechanical Characteristics
A model number interpretation diagram ap-
pears in gure 4. This diagram shows the various
basic congurations of the Camera.
Dimensions for the Camera are shown in g-
ure 5. Figure 6 is a detailed dimensional illustra-
tion for the optional mounting block that provides
threaded 1/4-20 mounting holes. The Camera
consists of a main body casting and front casting
assembly.
Interconnections are via a 12-pin connector
located on the rear panel.
An adjustable CS-mount adapter threads
onto the front of the casting. It is secured from
turning by a nylon tipped hex-socket head set-
screw.
The Camera can be mounted at any of three
places on its body:
1. By the CS mount directly to a microscope or
other similar device
2. By the top of the case — either with or without
the optional mounting block
3. By the bottom of the case — either with or
without the optional mounting block
Directly mounting to the top or bottom of the
housing requires removal of the two black button
head screws holding the outer housing cover in
place at that location (top or bottom). The op-
tional Accessory Kit contains the mounting block
and a pair of 2-56 × 3/8 stainless steel screws to
attach it to the Camera.
If the Camera is to be mounted directly with-
out use of the optional mounting block, a pair of
2-56 stainless steel screws of the required length
would have to be acquired. These are not sup-
plied.

Note that special-order Cameras and Camer-
as modied for special purposes may be shipped
with other items. The above listing are the basic
items for typical applications.
Table 3 lists the basic items supplied with a
Camera. Table 4 lists items supplied in an optional
accessory kit.
2.3 Equipment Required but Not
Supplied
If the following items were not ordered with
the Camera these will be required to make it op-
erational:
1. CS- or C-mount lens suitable for the sensor
format/size in Camera
2. Power supply, 5 V dc, 500 mA output or 12 V
dc, 350 mA
3. Cable. Refer to one of these test cables as an
example for the construction of an interconnec-
tion cable to be used with the Camera:
a. See gure 8 for use with a 5 V dc (manual
iris) versions of Camera. This cable shows
connections for the H and V drive option.
b. See gure 9 for use with auto iris or dc
iris version of Camera (12 V dc operating
power).
c. See gure 10 for use with a 12 V dc Cam-
era optioned for freeze frame operation.
(Requires use of a manual iris lens.) This
cable shows connections for the H and V
drive option.
4. 1/4-20 mounting bolt(s) of the proper length if
the mounting block is to be used.
2.4 Cabling Requirements
A single 12-pin connector (gure 7) on the
rear panel provides all electrical connections to
the Camera. Table 6 lists the mating cable plug for
this rear panel connector. Use this plug to con-
struct the cable for operating the camera.
Several test cables are shown in this manual.
They can be used as an example for wiring the
operating cable for a Camera.
Figure 8 shows the wiring arrangement for a
5 V dc (manual iris only) version of the Camera.
This cable provides for all operating capabilities of
a 5 V dc Camera.
A 12 V dc version of the Camera may require
a cable wired to either of two congurations. One
is for use when the Camera is internally cong-
ured for use with either an auto iris lens or a dc iris
lens. The other is for use when a 12 V dc Camera
is internally congured for freeze frame operation,
and/or external horizontal/vertical drive options.
1. Figure 9 shows the cable for use when a 12
V dc version of the Camera is congured for
either an auto iris lens or a dc iris lens.
2. Figure 10 shows cable wiring for use when
a 12 V dc Camera is internally congured for
either freeze frame operation or H and V drive.
Only a manual iris lens can be used when the
Camera is congured for either freeze frame
operation or H and V drive.

2.6 Sync Requirements
A standard camera is available in two differ-
ent versions related to sync:
1. Internal Crystal
2. Horizontal drive and vertical drive (12VDC
Camera only)
A camera optioned for either auto iris or dc
iris automatically has the Internal Crystal option.
Only a camera with the manual iris option
can also have the horizontal and vertical drive
option. Likewise a camera having the horizontal
and vertical drive option can only be a manual iris
camera.
H and V drive reverts to the internal crystal if
either of the inputs or both inputs are removed.
As a special order, the camera is also avail-
able with genlock. With genlock, the external sync
reference is applied to a single input on the rear
panel. This input must have both horizontal and
vertical pulses ( composite sync) and they can be
combined with video (composite video). Additional
details about the genlock feature is not covered in
this manual.
2.6.1 H and V Drive Characteristics
These are 75 ohm internally terminated
inputs. It is best to use 75 ohm coax especially
for longer runs. They trigger on negative edges at
standard TTL levels.
2.7 Mounting Requirements
The dimensions shown in gures 5 and 6
illustrate all relevant characteristics related to
mounting the Camera. Note that the CS-mount
adapter is adjustable. The dimension to the front
shoulder of the adapter is a nominal dimension.
Also note that the 1/4-20 threaded holes in the
bottom of the optional mounting adapter block are
meant to accept not more than 0.200-inch depth
from the mounting screws. A screw will bottom
out if an attempt is made to thread it deeper than
0.200 inch.
2.8 CS- and C-mount Adapters
Lenses must be suitable for use with size of
the sensor installed in the Camera (1/4-, 1/3-, or
1/2-inch). The front of the Camera body is tted
with an adjustable CS-mount adapter. It can be
rotated on its threads for back focus distance by
loosening a hex-socket head setscrew. (Figures 5
and 6 illustrate this setscrew at one location, but
since the CS mount rotates, it can appear in any
position.)
If a C-mount lens is to be used with the
Camera a 5 mm extender ring (in the optional
Accessory Kit) must be threaded onto the front of
the CS mount. This ring provide the proper back
focus distance for a C-mount lenses.
2.9 Serial Control Input (RS-232C)
Pins 8 and 9 on the rear panel connector
provide RS-232C serial communications (19,200
baud) for control of internal Camera functions.
The three parts of table 5 lists all 12 pin functions
on the connector for various congurations of the
camera.
2.10 Installation Procedure
Installing the Camera is straightforward. It is
only necessary to mount the Camera to a suitable
base, attach the lens, attach the rear panel con-
nector and apply power. This assumes the other
end of the cable is properly connected to a source
of power, a tv monitor, and any other required
equipment.
Figures 8 is an example cable diagram of a
test cable for use with the 5 V dc version of the
Camera. Only manual iris lenses can be used
with this Camera. The H & V drive leads are re-
quired only for a camera with this option.
Figures 9 and 10 are example wiring dia-
grams illustrating test cables available for use with
the 12 V dc version of the Camera.
Figure 9 is for use with either an auto iris
lens or a dc iris lens — depending on how the
Camera is internally congured.

AUTOMATIC OPERATION
Standard Feature Camera can be set up for unattended operation with no operator input
SERIAL REMOTE CONTROL FUNCTIONS
Programmable Aperture Correction
Modies high frequency response in camera circuits to enhance black-white
transitions in the scenes. Has the effect of making scenes look “sharper.” Can
be implemented for horizontal alone, vertical alone, or for both horizontal and
vertical simultaneously
Complex Gamma Curve Constructions Makes it possible to taylor a gamma curve for the types of scenes typically
viewed
2-D Mirroring Allows for horizontal and vertical to be independently reversed left-right and
top-bottom
Programmable backlight Compensation
involving window masking and histograms
Makes it possible to minimize the effect of bright areas of the scene outside the
areas of interest either by masking out those areas or by applying an integration
effect to a histogram of the scene brightness levels
Windowed Auto Exposure Makes it possible to window (select) an area of the scene upon which the auto
exposure circuits will operate.
Electronic Pan & Tilt When zoomed in from a full frame view, makes it possible to electronically move
right/left (panning), up/down (tilt), or rotated (angle viewed changes)
Negative Y and/or C Luminance (Y) can be reversed to make an negative image and/or color (C)
can be reversed or removed.
Monochrome Monochrome removes “C” (color) information from the video output so only the
luminance information is present
Freeze Freeze mode captures the current image of the scene and continues to provide
it as video output until this mode is deselected.
Programmable Blemish Correction Any pixel areas of the scene can be modied to the desired response and
stored as a permanent characteristic for that area
Presets Selections in the various GUI menus can be saved to a preset for easy recall
Auto/manual gain
Gain control can be set for either of two modes: 1. Automatic control by the
camera to maintain video output or 2. Manual gain control mode through menu
selections with the GUI
Shutter
The sensor can be made to collect light for less than the normal time (“Normal”
is 1/60 for NTSC or 1/50 for PAL). Nine selections are available up to 1/50,000
sec. Frames continues at the normal rate while shuttering.
Integration
The sensor can be made to collect light for enhanced sensitivity by menu
selection of integration times from 2 elds to 510 elds. The Camera continues
to output at its normal frame rate during this integration time but with the last
integrated eld until the next integrated eld is available.
White Balance
Three white balance modes are available. One is automatic white balance with
the camera circuits maintaining proper white balance. The second choice is
moving sliders on a GUI screen to change the white balance curves manually.
The third choice is the User mode in which it is possible to independently move
sliders on the red and blue response curves.

OTHER CAPABILITIES
Auto iris, dc iris, manual iris lens selec-
tions
All versions of the Camera can be used with a manual iris lens. A 12 V dc version
of the Camera can also be optioned for use with an auto iris lens or a dc iris lens
— or it can be optioned for the freeze frame mode of operation. Freeze frame
precludes use of an auto or dc iris lens.
Horizontal and vertical drive Manual iris versions of the camera can be optioned for H & V drive inputs. Camera
operates in crystal mode if H and V drive are not provided (revert to crystal).
Table 2. Capabilities (continued)
Figure 10 is for use when the Camera is in-
ternally congured for freeze frame operation or H
& V drive — in which case only a manual iris lens
can be used.
These diagrams show composite video
connected to a viewing monitor and the S-video
connected to a frame grabber in the PC. Either
video output can be used for the scene monitor
and frame grabber if they are capable of accepting
those inputs.
Freeze frame can also be implemented
through the serial link by using the GUI interface
on the PC. When the Camera is put into the freeze
mode, it stores the current scene and continues to
output that scene until the Camera is taken out of
the freeze frame mode.
As a minimum, the following must be con-
nected:
1. Operating power: either 5 V dc, 500 mA, or 12
V dc, 350 mA, depending on the version of the
Camera
2. RS-232C data communications with a PC run-
ning the test/setup GUI software
3. Either of these two video monitoring methods:
a. NTSC or PAL output on pin 4 of the rear
panel connector
b. The S-video outputs (Y on pin 10 and C on
pin 11)
Additionally, the following connections can be
made — depending on the requirements:
4. The freeze frame input TRIG (pin 5). This is
only for the manual iris versions of the Camera
5. The H & V drive connections if the camera has
this option. Only a manual iris lens version can
have this option. (12VDC Camera only)
6. The unused video output may also be used.
These outputs appear simultaneously.
7. An auto iris lens or a dc iris lens, depending on
which type lens a 12 V dc version Camera is
internally congured for — unless, of course, it
is congured for freeze frame operation.
3.0 OPERATION
After the Camera is installed, the actual op-
eration of the Camera is controlled by the related
frame grabber and image processing software.
The iris on a manual lens may have to be
opened and closed in response to changing scene
lighting conditions. The lens may also require
refocusing from time to time if the image changes
position, but otherwise there is no other attention
required for the Camera.
Camera functions are primarily controlled by
the GUI interface running on a PC. Figure 12 is
the “about” window for the current version of this
software.
Figure 13 shows the opening “home” window
of the 3610 Graphical User Interface (GUI). Most
control functions are performed from this window,
but two other windows accessible from the Misc
area also perform important functions:

3.1. DSP3600 GUI Home Screen
Figure 13 (DSP3600) is the primary control
window where all the various functions are ac-
cessible. Clicking various buttons in this window
causes drop down menus to appear. Table 7 lists
the various functions and gives a brief description.
Any selection of settings in the GUI can be
stored to one of the presets. Just select the de-
sired preset number (Preset 1 to Preset 10), then
click Save. If it is desired to make those (or some
other group of selections) the internal default of
the Camera, just click on the EEPROM button.
Those settings are then stored in Camera mem-
ory and remain as the Camera default settings
until other selections are stored by clicking on the
EEPROM button again. The GUI will remember
the factory default it is necessary to return to reset
conditions.
If a frame grabber is used to capture the
video output from a Camera, it too will have a GUI
interface for manipulation of Camera features.
3.1.1 Gamma Control
The gamma selections of the GUI make
changes to the luminance (black-white) char-
acteristic (Y-gamma). It can be set to any of 10
response curves.
Selections 0 through 7 are an increasingly
nonlinear video response as shown in gure 17.
These curves enhance video response in the
darker areas of a scene.
Selection 8 (bottom curve in gure 18) is a
standard linear video response. This may be the
most desirable choice when making measure-
ments where video level is a key factor.
Selection 9 (top curve in gure 18) is also
a linear response but with an approximate 15
percent increase in gain. This results in a slight
increase of noise in the video.
3.1.2 Freeze Image
The current eld from camera can be cap-
tured/frozen by either one of two methods: 1) By
checking the “freeze” box on GUI Screen. The
odd eld will be frozen in memory and displayed
until the Check is removed from “Freeze” box. 2)
By pulling the TRIG input line low (manual IRIS
camera only), the captured eld will be either
even or odd depending on timing of TRIG signal.

3.1.3 Back Light Compensation (BLC)
When the scene being viewed has a
darker image in front of a bright background
(such as a subject standing in front of a win-
dow at midday) a backlight condition results.
The Camera has four BLC modes to select
from when confronted with this situation.

3.1.3.1 Off (Fixed Weighted Average)
Select this compensation when the subject of
interest is a backlighted dark image that does not
move. The foreground subject will gain detail as
a result of being made brighter, but the backlight
area behind the subject will have a loss of detail
due to this overall increased brightness level. In
this mode, each of the window areas (ref: para-
graph 3) of the scene have xed values assigned
to them for determining how to render the overall
scene.
3.1.3.2 Automatic Weighted Average
Select this compensation when the subject
of interest is a backlighted image moving against
the bright background. The foreground subject will
gain detail as a result of being made brighter, but
the backlight area behind the subject will have a
loss of detail due to this overall increased bright-
ness level. In this mode, the weighting values are
automatically controlled in response to the light
intensity detection window.
3.1.3.3 Brighten Dark Areas
This selection enhances details of a darker
foreground subject that is backlighted. The bright
backlighted area will be made even brighter with a
resulting loss of detail.
3.1.3.4 Darken Bright Areas
Use this selection to enhance detail in the
backlighted area of the scene. The foreground
image is made even darker, but use of a gamma
curve can maintain detail of the foreground part of
the image if this is necessary.
3.1.4 Save Button
Clicking the Save button sends the current
GUI selections to the Camera. It will also store
them into any GUI Preset (1 to 10) that may cur-
rently be selected — other than in the Factory
Default selection. If Factory is the active preset,
then the current selections are not stored by the
GUI. (Also, clicking the save button is not

3.1.5 EEPROM Button
Clicking the EEPROM button stores the
current GUI settings in the Camera memory. This
then becomes the Camera default settings until
new settings are entered by pressing the EE-
PROM button again with different selections.
3.2 Lens/Aperture (Lens Dialog) Window
The Lens area of this screen (gure 14) pro-
vides settings for a dc iris lens, an auto iris (video
driven) lens, or for a manual lens for which no
settings are required.
3.2.1 Lens Area
Level offers selections from 109 to 149 for
setup of a dc iris lens. Dc Servo should be se-
lected for use with dc iris lens. Select Video Servo
for auto iris lenses.
3.2.2 Aperture Area
The Aperture area of this screen provides
settings for horizontal and vertical aperture. Table
8 lists these four settings together with the avail-
able values.
3.3 Set AE Windows (Set Weight)
Window
Automatic gain control for a typical Camera
is typically performed by monitoring the overall
scene video level and then making adjustments to
compensate when it becomes too high or too low.
The 3600 Camera, however, divides the
scene into ve areas that can be re-sized and
shaped as desired. Each area is assigned a rela-
tive weight (from 1 to 15) for its contribution to
the automatic gain control function of the Camera.
For example, a high intensity light in one corner of
the scene could be assigned a minimum inuence
upon gain by forming a small window over it and
then assigning that window a low value (perhaps
“1”).
Figure 15 shows the default size and loca-

tion for these windows. These lines can be pulled
to other locations by clicking and pulling on them
with a mouse. There is an underlying grid to which
they snap.
The Show Windows area of the screen
makes if possible to overlay the windowing lines
to the video of the scene. The location of these
buttons corresponds to the window areas shown
above. Clicking on a button turns on a transpar-
ent overlay for that window area. The All and
None buttons turns on and off an overlay of all the
areas.
Reset to Default re-sizes the window grids to
the factory set default size/locations.
Clicking the close button closes the window.
4.0 STATIC DISCHARGE PROTECTION
Procedures in this manual do not require
entry into the housing of the Camera. However in
the event that an open unit were available, the fol-
lowing precautions should be followed:
CAUTION
This Camera contains sensitive devices
that can be damaged by static discharge.
Use appropriate static control methods
when working inside the Camera.
Components used in modern electronic
equipment, especially solid state devices, are
susceptible to damage from static discharge. The
relative susceptibility to damage for semiconduc-
tors varies from low with TTL to high with CMOS.
