INSTALLATION AND OPERATION
3950 iVIEW
1.0 GENERAL DESCRIPTION
The 3950 iView series is a camera system that
integrates a high performance digital signal processing camera, pan-and-tilt Positioner, and control
receiver into one package.
Throughout this manual the entire assembly will
typically be referred to the “3950,” the “Positioner” or
the “iView.”
Specifications are cont ained in table 1. A model
number interpretation is provided in figure 2. This
can be used to interpret an existing model number.
WARNING
Some versions of this Positioner operate from
115 V ac or 230 V ac. Use all appropriate care
when installing and maintaining any equipment operating from these voltages.
1.1 ELECTRICAL CHARACTERISTICS
The camera uses digital signal processing (DSP).
It has an internal source ID generator. Integration
control plus a built-in video storage card provides full
color continuous video even at very low light levels.
The positioner speeds are variable with maximums of 100° per second in pan mode and 20° per
second in tilt while sustaining 90 mph winds. Pan
range is a continuous 360 degrees while the tilt
range is +40 to -90 degrees from the horizontal.
There are 64 preset positions with a preset accuracy of one-quarter degree. When responding to
standard pan-preset the Positioner can move with a
pan speed of 100° per second.
This camera/positioner will operate in temperature
ranges from -40° to +55° C and with winds of up to
90 mph. The enclosure protects against salt, grime,
dirt, and moisture.
Each iView “address” within a surveillance system
can be selected electronically from the Monitoring
Center. There are no mechanical dip switches to set
at the camera, and each unit responds to the central
command only if addressed. This provides greater
integration flexibility for the designer and more
dynamic camera control for the operator
1.1.1 Control Software
The Cohu camera system control software, is
designed to control the camera, camera DSP
functions, positioner, lens functions, as well those of
auxiliary equipment such as VCRs, screen splitters,
and monitor selection. The protocol and message
structure for camera is common for all cameras. No
proprietary protocol and message structure is used.
Three versions of control software are available:
Win MPC
Win MPC Graphical User Interface (GUI) software
is available for setting the address and performing
field tests for each iView . This can be obtained at no
cost from either the cohu-cameras.com web site or
by mail on floppy disk
Cams
The Cams protocol software is intended for
controlling multi-camera/positioner systems when
the Cohu MPC Master Control Panel is the central
control “intelligence” for the system. All control and
respond commands among the various equipment
in the system pass through the Master Control
Panel.
Net Cams
The Net Cams software is intended for controlling
multi-camera/positioner systems when a Windows
based PC is the central control “intelligence” for the
system. All control and respond commands among
the various equipment in the system pass through
the Net Cams Server.
The integrated receiver/driver, cont ained within the
iView, communicates using Cohu protocol messages to control all camera functions. All iView
functions are operable via RS-422 serial communications.
The Positioner is fully compatible with existing
Cohu controllers. In case of power failure, all 64
preset positions of all Positioners are stored in
nonvolatile memory .

1.2 MECHANICAL CHARACTERISTICS
Although the camera/positioner is a single mechanical assembly for installation purposes, it
actually consists of two subassemblies: (1) the
camera and (2) the positioner.
All camera circuits are contained within a sealed
and pressurized environmental housing having a
clear window at one end for viewing by the camera

lens. This barrel is fully covered by a sun shield
spaced slightly away from the housing itself. This
minimizes heat buildup due to sunlight and also
serves to minimize sun flair by shading the lens at
some camera angles.
The pan/tilt positioner is a sealed unit intended for
outdoor use under rain, snow , and other typical
harsh weather conditions. Either a small (PEDD) or
larger (LPED) mounting base is installed to the pan/
tilt positioner depending on the model of iView
ordered.
A single multiconductor cable passes through the
base to provide for all signal and operating power
connections for both the pan/tilt unit and the camera.
This 34-inch cable has a 16 pin connector at the
other end for connection with the system cable
routed to its area.

A Schrader valve on the rear panel of the camera
should be used to add dry nitrogen up to 5 psig

event a “Low Pressure” message is received from
the control software.
2.0 INSTALLATION
An iView can typically mounted in any one of three
mechanical configurations depending on the mounting accessories supplied. This is determined by the
model number:
1. Pedestal Mount (PEDD and LPED models)
The simplest configuration. Only the iView is
supplied. It bolts directly onto the top of a site-
supplied pedestal having the
correct hole pattern or to an
adapter plate providing the proper
hole pattern. Figure 3 illustrates a

Figure 4 shows the larger LPED
base. It has two four-hole patterns on it. Depending on the
model of iView ordered one of
these two plates will be attached.

INSTALLATION AND OPERATION
3950 iVIEW
2. Wall Mount (WALL model)
This mounting arrangement requires an arm that
bolts to the wall and an adapter plate between the
arm and the bottom of the Positioner. The arm is
typically supplied with this adapter plate already
installed.
3. Pole Mount (POLE model)
This mounting arrangement is similar to the Wall
Mount -- except that the mounting arm attaches to a
bracket fastened to a pole instead of directly bolting
to a wall.
Table 2 summarizes the major items supplied for
each of these three installation methods. Each of
these installations will be expanded upon in a later
sections.
2.1 UNPACKING AND RECEIVING INSPECTION
This item was thoroughly tested and carefully
packed in the factory. Upon acceptance by the
carrier, they assume responsibility for its safe arrival.
Should you receive this item in a damaged condition,
apparent or concealed, a claim for damage must be
made to the carrier.
in the event that an open unit were available, the
following precautions should be followed:
CAUTION
This Positioner/Camera contains sensitive devices
that can be damaged by static discharge. Use appropriate static control methods when working inside either the Positioner or Camera.
Components used in modern electronic equipment, especially solid state devices, are susceptible
to damage from static discharge. The relative
susceptibility to damage for semiconductors varies
from low with TTL to high with CMOS. Most other
semiconductors fall between TTL and CMOS in
susceptibility to static discharge. As a minimum,
therefore, observe the following practices when
working inside this or any other electronic equipment:
1. Use conductive sheet stock on the work bench
surface.
2. Connect the sheet stock to ground through an 1
megohm or greater value resistor.
To return the product to the factory for service,
please contact the Customer 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 discovery of the
concealed damage. Keep all cartons and packing
materials.
Since shipping damage is the carrier's responsibility , the carrier will furnish you with an inspection
report and the necessary forms for filing the concealed-damage claim
2.2 STATIC DISCHARGE PROTECTION
Procedures in this manual do not require entry
into the housing of the positioner/camera. However
6
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 loose
their static protection properties.
This list serves as a reminder of the minimum
acceptable practices. Be sure that all static discharge devices at the work bench are properly
installed and maintained.“ S tandard grounding mat s
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.

2.3 EQUIPMENT SUPPLIED
Depending on the mounting configuration, several
variations of equipment can be supplied. See table 2
for a list of the basic differences between models as
related to mounting.
PEDD (Small Pedestal Base). See figure 3.
Pedestal mounting is the most basic of the three
mounting arrangements. Taller pedestals should
have an access plate near the top so that a strain
relief can secure the cable assembly in place. This
not only prevents the weight of the cable from pulling
on the connector but it is also a good general practice with all cable runs.
LPED (Large Pedestal Base) See figure 4.
The Large Pedestal Base option (figure 4) provides an 8.5-inch diameter base plate having two
four-hole patterns for mounting to various pole and
arm platforms currently installed at many locations.
One hole pattern is on a 7.00-inch diameter with
the four holes spaced 90 degrees apart.
8
Base is permanently attached to the iView
Farther out from that pattern is a 7.25-inch diameter pattern displaced by 22.720 degrees from the
first pattern. This pattern also consisting of four
holes spaced 90 degrees apart.
All eight of these mounting holes are of 0.380inch diameter. Up to 3/8-inch mounting hardware
can be used. Stainless steel hardware should be
used.
WALL (Wall Mount). See figure 5.
With a wall mount, the Pedestal bolts to the end of
an arm which is attached to a wall. Figure 6 gives
dimensions of the arm and adapter plate. This arm
is typically shipped with the adapter bracket attached. This wall must not only have four mounting
bolts but also a hole centered between these bolts
through which the cables must pass. A weather-tight
gasket should be used between the arm and wall.
Since the Positioner pigtail cable is about 34 inches
long it is likely that the connectors will be behind or
inside the wall or junction box in that area.
