1.0GENERAL DESCRIPTION
This introduction briefly describes overall
characteristics of the amera (figure 1) related to
its installation and operation.
1.1Electrical Characteristics
The 3610 Series provides a small, light-
weight, highly sensitive machine vision D
amera 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-232 serial interface with the
amera.
The amera operates in either NTS or PAL
format depending on the model. This amera
operates at an internal clock rate of 28.63636
MHz (NTS ) or 28.375 MHz (PAL). Table 1 lists
specifications for this 3610 amera.
Table 2 is a list of major features of the
amera  primarily those associated with the
GUI.
The amera is available in two different
operating power configurations: 5 V dc and 12 V
dc. Only manual iris lenses can be used with the
5 V dc amera. The 12 V dc ameras are avail-
able in three configurations: (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.
1.1.1 Sensor Characteristics
Figure 2 shows the relative response char-
acteristic of the sensor. These characteristic
curves apply to both NTS and PAL sensors.
The curves show yan, Green, Yellow and
Magenta responses.
The chart excludes both lens characteristics
and light source characteristics.
Note however that the IR cut filter shown in
figure 3 will modify the overall response of the
amera to light. This low pass filter 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
amera.
1.2Mechanical Characteristics
A model number interpretation diagram
appears in figure 4. This diagram shows the
various basic configurations of the amera.
Dimensions for the amera are shown in
figure 5. Figure 6 is a detailed dimensional
illustration for the optional mounting block that
provides threaded 1/4-20 mounting holes. The
amera consists of a main body casting and front
casting assembly.
Interconnections are via a 12-pin connector
located on the rear panel.
NOTE: This equipment has been tested and found to comply with the limits for a lass A digital device,
pursuant to Part 15 of the F Rules. These limits are designed to provide reasonable protection against
harmful interference when the equipment is operated in a commercial environment. This eqiupment gener-
ates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications. Operation of this equipment in
a residential area is likely to cause harmful interference in which case the user will be required to correct the
interference at his own expense.
AUTION: hanges or modifications to this de-
vice not expressly approved by ohu Electronics
could void the user's authority to operate the de-
vice.
This device complies with Part 15 of the F Rules.
Operation is subject to the following two conditions:
(1) this device may not cause harmful interference,
and (2) this device must accept any interference re-
ceived, including interference that may cause un-
desired operation.

igure 3. IR Cut ilter Response
Characteristics
An adjustable S-mount adapter threads
onto the front of the casting. It is secured from
turning by a nylon tipped hex-socket head set-
screw.
The amera can be mounted at any of three
places on its body:
1. By the S 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 optional
Accessory Kit contains the mounting block and a
pair of 2-56 × 3/8 stainless steel screws to attach it
to the amera.
If the amera is to be mounted directly
without 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
supplied.
2.0INSTALLATION
In addition to the actual installation require-
ments, this section covers a number of other
items including proper shipping and handling of
the amera.
2.1Unpacking and Receiving
Inspection
This item was thoroughly tested and care-
fully packed in the factory. Upon acceptance by
the carrier, they assume responsibility for its safe
arrival. Should you receive this item in a dam-
aged condition, apparent or concealed, a claim
for damage must be made to the carrier.
To return the product to the factory for
service, please contact the ustomer Service
Department for a Return Authorization Number. If
a visual inspection shows damage upon receipt
of this shipment, it must be noted on the freight
bill or express receipt and the notation signed by
the carrier's agent. Failure to do this can result in
the carrier refusing to honor the claim.
When the damage is not apparent until the
unit is unpacked, a claim for concealed damage
must be made. Make a mail or phone request to
the carrier for inspection immediately upon dis-
covery of the concealed damage. Keep all car-
tons and packing materials.

2.2Static Discharge Protection
Procedures in this manual do not require
entry into the housing of the amera. However in
the event that an open unit were available, the
following 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.
omponents 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 MOS.
Most other semiconductors fall between TTL and
MOS in susceptibility to static discharge. As a
minimum, therefore, observe the following prac-
tices when working inside this or any other elec-
tronic equipment:
1.Use conductive sheet stock on the work bench
surface.
2. onnect the sheet stock to ground through an 1
megohm or greater value resistor.
3.Use a wrist strap connected to ground through
an 1 megohm or greater value resistor when
working at the bench.
4.Maintain relative humidity of the room above 30
percent. This may require a room humidifier.
Working on circuits with relative humidity below 30
percent requires extraordinary procedures not
listed here.
5. Use antistatic bags to store and transport an

exposes chassis, circuit boards, and components.
Use new antistatic bags. Old, used bags lose their
static protection properties.
This list serves as a reminder of the mini-
mum acceptable practices. Be sure that all static
discharge devices at the work bench are properly
installed and maintained. Standard grounding
mats and wrist straps purchased for use at work
benches are supplied with leads having current
limiting resistors for safety. Never substitute with
a grounding lead not having the resistor.
AUTOM AT IC OPERATION
Standard Feature Camera can be set up for unattended operation with no operator input
SERIAL REMOTE CONTROL FUNCTIONS
Programmable Aperture Correction
Modifies 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 histrograms
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 histrogram 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. Likewise, an area of the scene can be windowed
(selected) upon which the auto white balance circuits will operate.
Electronic Pan & Ti lt When zoomed in from a full frame view, makes it possible to electronically move
right/left (panni ng), up/down (tilt), or rotated (angle viewed changes)
Negative Y and/or C, monochrome, freezeLuminance (Y) can be reversed to make an negative image and/or color (C) can
be reversed or removed. Image can be frozen
Programmable Blemish Correction Any pixel areas of the scene can be modified 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 (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 fields to 510 fields. The Camera continues
to output at its normal frame rate during this integration time but with the last
integrated field until the next integrated field 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 for
by moving sliders on a GUI screen to change the white balance curves manually.
The other 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 selections
All versions of the Camera can be used with a manual iris lens. Automatic iris
lenses can be used with the 12 V dc version of the Camera  unless it has
been optioned for the freeze frame mode of operation. These automatic iris
lenses can be either a video driven auto iris lens or a dc iris lens (depending on
which of these two lens options had been chosen for the Camera configuration).

Figure 8 shows the wiring arrangement for a
5 V dc (manual iris only) version of the amera.
This cable provides for all operating capabilities
of a 5 V dc amera.
A 12 V dc version of the amera may
require a cable wired to either of two configura-
tions. One is for use when the amera is inter-
nally configured for use with either an auto iris
lens or a dc iris lens. The other is for use when a
12 V dc amera is internally configured for
freeze frame operation.
