INSTALLATION AND OPERATION 3950 iVIEW
1.0 GENERAL DESCRIPTION
The 3950 iView series is a camera system that
integrates a high performance digital signal process-
ing 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 contained in table 1.Amodel
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 equip-
ment 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 maxi-
mums 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 accu-
racy 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.
The integrated receiver/driver, contained within the
iView, communicates using Cohu protocol mes-
sages to control all camera functions. All iView
functions are operable via RS-422 serial communi-
cations.
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.
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.
1.2 MECHANICAL CHARACTERISTICS
Although the camera/positioner is a single me-
chanical 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

6X-1027a 5
INSTALLATION AND OPERATION

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
(pounds square inch gauge) to the barrel in the
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 mount-
ing accessories supplied. This is determined by the
model number:
1. Pedestal Mount (PEDD and LPED mod-
els)
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
small diameter pedestal mount
base attached to the iView.
Figure 4 shows the larger LPED
base. It has two four-hole pat-
terns 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.
To return the product to the factory for service,
please contact the Customer Service Department
for a ReturnAuthorization 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 responsi-
bility, the carrier will furnish you with an inspection
report and the necessary forms for filing the con-
cealed-damage claim
2.2 STATIC DISCHARGE PROTECTION
Procedures in this manual do not require entry
into the housing of the positioner/camera. However
in the event that an open unit were available, the
following precautions should be followed:
CAUTION
ThisPositioner/Cameracontains sensitivedevices
that can be damaged by static discharge. Use ap-
propriate static control methods when working in-
sideeitherthe Positioneror Camera.
Components used in modern electronic equip-
ment, 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 equip-
ment:
1. Use conductive sheet stock on the work bench
surface.
2. Connect the sheet stock to ground through an 1
megohmor greatervalue resistor.
3. Use a wrist strap connected to ground through an 1
megohmor greatervalue resistorwhen workingat
thebench.
4. Maintainrelative humidityoftheroomabove30
percent.Thismayrequire aroom humidifier.
Working on circuits with relative humidity below 30
percentrequires extraordinaryprocedures not
listedhere.
5. Use antistatic bags to store and transport an
exposes chassis, circuit boards, and components.
Use new antistatic bags. Old, used bags loose
theirstaticprotection properties.
This list serves as a reminder of the minimum
acceptable practices. Be sure that all static dis-
charge 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 ground-
ing lead not having the resistor.

INSTALLATION AND OPERATION 3950 iVIEW
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 prac-
tice with all cable runs.
LPED (Large Pedestal Base) See figure 4.
The Large Pedestal Base option (figure 4) pro-
vides 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.
Farther out from that pattern is a 7.25-inch diam-
eter 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 0.380-
inch 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 at-
tached. 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.

Figure 5. Typical Wall Mount Installation
POLE (Pole Mount). See figure 6.
Mounting to a pole is similar to mounting to a wall.
For mounting to a pole, the four mounting bolts are
provided by a bracket. This bracket is attached to
the pole by stainless steel straps. This strapping
requires a special tensioning tool (type 7411411-
001).
Cable routing when using a pole mount depends
the situation encountered. It can either be directed
down behind the pole bracket or, if arrangements
have been made for this, into the pole. Junction
boxes, drip loops, and weather proof integrity of the
connectors must be considered before starting the
installation.
2.4 EQUIPMENT REQUIRED BUT NOT SUPPLIED
Each installation can have different requirements,
so an accurate list of items required for all situations
is not possible. The following is a typical require-
ment:
1. 5/16-inch grade 316 stainless steel mounting
hardware
2. Tensioningtool(polemounting)(type7411411-001)
3. Gasketmaterialand/or sealingcompound for
waterproofing
5. Cable,multiconductoror individualcables

2.5 POWER REQUIREMENTS
Depending on the model, a Positioner requires
either 24 V ac 60 Hz, 115 V ac 60 Hz, or 230 V ac 50
Hz power.
Nominal power with heaters off is 46 watts. In cold
weather with the heaters on, power consumption
increases by 7.5 watts each time they cycle on.
All electrical connections to and from the
Positioner are made through a single permanently-
attached cable entering the bottom of the base plate.
This same cable also contains signals and video
wiring.
2.6 PEDESTAL MOUNT INSTALLATION
Mounting an iView on top of a pedestal is the most
basic installation. The iView base bolts directly to the
top of the pedestal (or to an adapter plate if re-
quired). The four-bolt hole pattern is on a standard
4.75-inch diameter circumference.
Proceed as follows for installation on a pedestal:
1. Route the cable pigtail down into the pedestal.
This cable should be secured by a strain relief
andnotallowed tohang freewithinthe pedestal.
(If an access plate is not available at the top of
the pedestal, the system cable must first be
connectedtothe pigtailconnector.)
2. Bolt the iView to the pedestal – using stainless
steelhardware.
3. Attach the camera pigtail connector to the
system connector. This often is done through a
removable access plate. Be sure these cables
are secured with a strain relief so that they do
nothang free.
4. Verify that the iView will have a full range of
movementwithoutstriking anynearby struc-
ture.
5. Proceed to section 2.10 to set up and check out
the iView.

adapter plate on the arm matches its hole pattern to
the hole pattern of the iView.
1. Verify that the system cable is accessible for
connection to the iView pigtail cable at the
mountinglocation.
2. Attach the adapter plate to the wall mount arm.
3. Route the system cable out of the wall and into
the back of the wall mount arm. Continue the
cable through the arm and out the hole at the
iViewmountinglocation.
4. Install a weather tight gasket between the arm and
thesurfaceof thewal — ifrequired.
5. Bolt the Arm to the wall.
6. Attach the two connectors to each other and feed
excess cable into the arm.

Always pre-plan all system cabling before starting
an installation. Before an iView is bolted in place, the
system cable must be available to attach to the
pigtail cable at the mounting location.
Figure 9 shows the cable wiring between the
iView and a Local Control Panel typically located in
a nearby equipment cabinet. This Panel is optional.
It is used when a local control panel is desired for
setup and maintenance operations.
If such a panel is not used then the interconnec-
tions shown in figure 10 must be made. In this case
a nearby junction box becomes the connection point
between an iView site and the distant Central Con-
trolStation.
Figure 11 is an assembly diagram for the cable
used between the iView and a typical junction box
having a terminal strip for all connections. This cable
has five stripped wire leads for the data connections
and also stripped leads for the ac power plug BNC
video connector.
Figure 12 is the assembly diagram for the cable
used between an iView and a typical junction box.
This cable has an ac power plug, BNC video con-
nector, and stripped leads for data connections at
the junction box.
Figure 13 is an assembly diagram for the cable
used between an iView and a junction box having
RS-232 data communications available. This cable
has an RS-232 to RS-422 converter wired in for data
communications with the RS-232 sources. This
cable also has an ac power plug and the BNC video
connector like the previous cable.

iView connector for either 115 or 230 V ac operation.
Pin functions for the 24 V ac version of an iView
are not shown in this manual.

with its mating system cable plug, it is recom-
mended that for additional protection against mois-
ture in severe conditions a sealing wrap be used on
the two connectors. Since this product adds bulk to
the connectors first verify that they can be routed
through any conduit or small radius bends if such a
sealing wrap is added.
Coax-Seal is the recommended product:

This product is available from a variety of com-
mercial supply houses, consumer stores, and in the
U.S. Government supply channels as GSA Schedule
GS-07F-5739R.
This material is a thick tape-like material sepa-
rated by a paper divider in its roll to prevent bonding
to itself before use.After this material is wrapped
around a connector it forms a permanent weather-
tight seal.
The cable and connector should be clean and dry
before wrapping with coaxseal.
Use a full wrap of the tape on the cable at the
beginning, then continue with a diagonal half-overlap
wrap up to the rear panel of the camera and finally
another full wrap at the end of the coverage.
The wrap then should be squeezed slightly to-
gether by hand to remove air gaps and ensure it has
moulded itself to the cable and connector.
This sealer will fuse itself together after a while
and removal will require cutting it off.

tions accompanying this product for more informa-
tion .

2.10 GUI INTERFACE
Several GUI interfaces are available for use with
theiView.
1. Win MPC is used to control a single iView during
installationormaintenanceoperations.This can
be done either at a central shop facility or at the
site location of the iView.
2. CAMS is used to control multiple iView systems
when an MPC Master Control Panel is being used
as the central control point.
3. NET Cams is used to control systems with mul-
tiple iView when the central control is a Net Cams
Server.
2.10.1 Win MPC Setup
When Win MPC (figure 17) is used to set up the
iView, it must be isolated from all other iViews in the
system. This generally is no problem since the iView
setup is performed either at a test bench location or
at the actual iView site itself. If the address setting
function of Win MPC were to be sent to multiple
iViews they would all have identical addresses
programmed into their memory. Since all iViews
(and other addressable equipment) in a system
must have a unique address, this would result in an
inoperative system.
2.10.2 Establishing Communications
Since each iView in the system must have a
unique address, it is probably best to set all iView

WITH CA-297C CABLE
This converter converts the RS-232 output of a PC to
RS-422 for communications with an iView during field
setup and testing.
A local PC with Win MPC software typically is used in
this application.
If this converer is plugged into the RS-232 output from
an F/0 converter, 12 V dc operating power will likely have
to be applied to the 12 V dc terminal lugs. These F/O to
RS-232 converters typically do not have sufficient cur-
rent on the handshake lines to power the 232/422 con-
verter. This application of the 232/422 converter would
typically occur as part of a fixed installation inside an
equipment cabinet located near an iDome. The 232/
422 converter would be part of a type CA-297C cable.

distribution location prior to sending each of them
out to the field installation sites. Providing a central
control location for all address assignments may
ensure that no duplications occur.
Before the address can be set or any other
setups made, it is necessary to establish commu-
nications with the iView. Figure 18 shows the home
