3960 CAMERA
INSTALLATION AND OPERATION
1.0 GENERAL DESCRIPTION
This introduction briefly describes the overall
characteristics of the Model 3960 Camera/
Positioner (figure 1) related to its installation and
operation.
1.1 Electrical Characteristics
The 3960 provides a highly sensitive CCD
camera in a pressurized housing together with a
high performance pan/tilt positioner environmen-
tally sealed from the environment..
All electrical connections are via 11 pins of a
single 16 pin connector on the end of a 34 inch
permanently attached “pigtail” cable. Table 1 lists
electrical and mechanical specifications for the
3960.
The 3960 is available with either NTSC or PAL
video output, depending on the model. Operating
power is either 24 V ac or 115 V ac — again de-
pending on the model.
It has a day/night feature that increases sensi-
tivity by reverting from color to monochrome output
in low light conditions. This feature can be made to
operate automatically or by manual control when
desired.
A model number interpretation diagram ap-
pears in figure 2. That diagram shows the various
basic configurations of the 3960.
1.1.1 Initial Setup Software
Win MPC Graphical User Interface (GUI)
software is available for setting the address and
performing field tests and setups for each camera/
positioner. This can be obtained at no cost from
either the cohu-cameras.com web site or by mail on
CD ROM for no cost. This test/setup software does
not control auxiliary equipment such as video
switchers, screen switchers, VCR’s, and such.
A separate manual is available for the Win
MPC software. The part number for that manual is
6X-1032. A suffix may be attached to this basic part
number to indicate the latest revision level of the
manual, but it can be downloaded or ordered using
the basic part number with the latest suffix.
To operate the 3960 in a system after setup by
WinMPC, either Cohu system software or some
common third-party software can be used, depend-
ing on the requirements of the installation.
1.1.2 Cohu System Control Software
The 3960 can be operated by either the Cohu
Cams or NetCams software or by a variety of other
common third-party software protocols. Not all
features may be available with some of these third-
party protocols. The protocols currently supported
are listed in both the specifications table and the
model number interpretation diagram.
The Cohu 3960 system control software is
designed to control the camera, the camera DSP
functions, lens functions, positioner pan/tilt func-
tions, as well those of auxiliary equipment such as
video switchers, screen splitters, monitor selectors,
VCR’s, and other such equipment. The protocol and
message structure for the camera is common for all
cameras. No proprietary protocol and message
structure is used. Two versions of control software
are available:
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 control-
ling multi-camera/positioner systems when a Win-
dows 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.
1.1.3 Other Control Software/Protocols
During initial setup and testing of a 3960, the
Cohu WinMPC software is typically used for com-
munications with the camera module and pan/tilt
positioner section of the 3960. This is typically done
with the software running on a windows based PC
at a test bench or at the installation site location..
Once the 3960 is ready to be released for service at
its installation site, a “working” protocol can be
selected for use in the control system. The currently

of these protocols may not support all functions of
the 3960.
1.2 Mechanical Characteristics
Dimensions are shown in figure 8. The 3960
consists of a sealed, pressurized camera module
mounted together with a high performance
positioner (pan/tilt unit) that is sealed from rain,
dust, dirt, and other undesirable contaminants. The
pan/tilt assembly is environmentally sealed but not
pressurized.
The moulded housing provides an integral sun
shield over the camera module housing to prevent
heat build up that could result from direct sun light
on the camera module housing.

Table 1. Specifications (continued)
All electrical connections are made via a 34-
inch pigtail cable permanently attached to the
bottom of the 3960 base. A connector with positions
for 16 pins is connected to this cable to provide all
electrical connections. Only 11 of these pin loca-
tions are used.
A Schrader valve (figure 14 — the car tire type
air valve on the left) on the rear panel provides for
pressurizing the housing with dry nitrogen. This
valve can be used to occasionally add dry nitrogen
as necessary to maintain pressure in the barrel at
about 5 psig (35 kPa). (Note: psig refers to pounds
square inch gauge — which designates pressure
relative to the altitude above sea level at which it is
being measured.)
During shipping, at which times high altitude
might be encountered during aircraft transportation,
a pressure relief valve on the rear panel (figure 14)
may release some pressure. Back at low altitudes
this would be experienced as a housing pressure
below the standard 5 psig (35 kPa). Dry nitrogen
should be added to bring the pressure back up to 5
psig (35 kPa). During normal purging and pressur-
ization, internal pressure should not be allowed to
rise above a 5 to 8 psig (35 to 55 kPa) range to
prevent stress on the seals.

The pressure relief valve should be lifted off its
seat during purging of the camera. This aids in the
flow of gas through the housing while purging
moisture laden air from inside.
The mounting base for the 3960 has a four-
hole pattern for attachment to a pedestal, mounting
arm, or other suitable base. High quality (grade
316) stainless steel bolts and lock washers should
be used. An additional add-on base plate is avail-
able to provide additional hole patterns on a larger
diameter.
A 3960 can be mounted in any one of six
mechanical configurations depending on the mount-
ing accessories supplied. The model number
defines the mounting equipment supplied as part of
the 3960. Table 2 shows the mounting items sup-
plied for each of the mounting configurations avail-
able with a 3960.
2.0 INSTALLATION
This section covers the general requirements
of installing the 3960 including cabling, power
requirements, and pressurization considerations. In
addition to the actual installation requirements, this
section covers a number of other items including
static discharge protection and proper shipping and
handling of the 3960.
Section 4 at the rear of this manual covers the
various mounting brackets, their dimensions, and
Figure 3. Optional LPEDD Adapter Plate
86X-1050a
3960 CAMERA INSTALLATION AND OPERATION
general installation requirements of bolting the 3960
in place. . A prime consideration will be routing of
the system cable to a 3960. This must be planned
for during the initial consideration of an installation
location.
These mounts should be installed only by
qualified installers thoroughly familiar with the
various code requirements and industry standard
best practices for an installation.
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 dam-
age must be made to the carrier.
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 respon-
sibility, the carrier will furnish you with an inspection
report and the necessary forms for filing the con-
cealed-damage claim.
To return the product to the factory for service,
please contact the Customer Service Department
for a Return Authorization (RA) Number.
2.2 Static Discharge Protection
Procedures in this manual do not require entry
into the housing of the 3960. But in the event that a
disassembled 3960 is being handled, the following
precautions should be followed:
CAUTION
This3960containssensitivedevicesthat can bedam-
agedby static discharge. Useappropriate static con-
trol methods when working inside the 3960.
Components used in modern electronic equip-
ment, especially solid state devices, are susceptible
to damage from static discharge. The relative sus-
ceptibility to damage for semiconductors varies from
low with TTL to high with CMOS. Most other semi-
conductors fall between TTL and CMOS in suscepti-
bility 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 a 1
megohm or greater value resistor.
3. Use a wrist strap connected to ground through a 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
exposed 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 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.
2.3 Equipment Supplied
The assembly consists of a pressurized camera
housing and environmentally sealed positioner (pan
and tilt) assembly. The housing is fitted with an
integral sun shield assembly that covers the camera
module housing. This sun shield minimizes heat
buildup inside the camera by shielding it from the
direct rays of the sun. Table 3 lists the items sup-
plied.A connector is supplied to mate with the 3960
pigtail connector. This connector is to be wired to the
system interconnection cable. See table 3.

3960 CAMERA
INSTALLATION AND OPERATION
Figure 8. Dimensions, Model 3960
422/232 converter will be required. Most PC’s have
only a serial RS-232 communications port.
Installing the 3960 will also require high quality
stainless steel (preferably grade 316) mounting
bolts and a platform of some type on which to
mount it. Gasket materials and sealing compounds
may also be required to provide waterproofing of
mounting holes in structures.
For installing with a pole mount (POLE option),
a tensioning tool is available to snug up the stain-
less steel straps holding the mount to the pole.
2.5 Cabling Requirements
All electrical connections for the 3960 route
through a permanently attached 34-inch cable. This
cable is attached to the bottom of the 3960 housing.
A 16 pin connector is attached to the free-hanging
end of the cable.
A mating connector is supplied for making
system interconnections. This connector should not
be attached to the system cable until it is known that
If the optional large mounting base is ordered
(LPEDD option) it will be supplied with four 1/4-20 x
3/4 mounting screws. If the plate is factory installed
these screws will be used for that installation and
not supplied as loose parts.
2.4 Equipment Required but Not Supplied
Table 4 is a list of equipment that may required
to install and make use of the 3960. As a minimum
the 3960 requires a source of operating power, a
monitor on which to view the scene, an interconnec-
tion cable, and a computer running Graphical User
Interface (GUI) software for control of the 3960 if
this is desired. Programming the optional ID gen-
erator messages requires a GUI software such as
the Cohu WinMPC setup and maintenance soft-
ware. This is available at no cost from Cohu Elec-
tronics:
www.cohu-cameras.com
During maintenance and setup operations
using either a laptop or desktop PC it is likely that a
10 6X-1050a
3960 CAMERA INSTALLATION AND OPERATION
the cable can be routed through any narrow places
(such as conduit) with the connector attached. Note
that bends and turns in a routing can sometimes be
difficult with an attached connector.
Figure 11 shows a typical test setup intercon-
nection diagram for the 3960 using a laptop PC
running WinMPC as the control point. Test cables
CTC-30 (115 V ac) and CTC-35 (24 V ac) are
available for this purpose.
Figure 16 shows four versions of a typical
system interconnection cable. Only 11 of the pin
locations on the connector body are used for the
two versions of the 3960 (24 V ac and 115 V ac).
Note that different pins are used for the power
input. Pin 12 is used for the line (hot) lead for 115 V
ac and pin 16 for one lead of 24 V ac.
Always pre-plan all system cabling before
starting an installation. Before a 3960 is bolted in
place, the system cable must be available to attach
to the pigtail cable at the mounting location.
Figure 16A is an assembly diagram for the
cable used between the 3960 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 16B is the assembly diagram for the
cable used between a 3960 and a typical junction
box. This cable has an ac power plug, BNC video
connector, and stripped leads for data connections
at the junction box.
Figure 16C is an assembly diagram for the
cable used between the 3960 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.
Figure 16D shows the cable wiring between
the 3960 and an optional Cohu Model 9300 Local
Control Panel (figure 15).
This panel is typically located in a nearby
equipment cabinet. It is used when an on-site local
control panel is desired for setup and maintenance
operations. This panel typically is installed in a
weatherproof cabinet located near the 3960 instal-
lation location. This optional panel can control
some functions of the 3960 without use of a local
laptop PC running WinMPC.
But a front panel BNC connector on the 9300
provides for connecting the RS-232 serial port of a
laptop PC to communicate with the 3960 using
WinMPC. When a 9300 local control panel is
installed at the 3960 site location, it becomes the
site address for the 3960. Any address pro-
grammed into the 3960 is not seen by the system.
Figure 12 is the assembly diagram for a test/
setup cable intended for use during setup and
maintenance operations of a 115 V ac 3960. This
cable is intended for use with the RS-232 output of
a laptop or other type PC; thus, an RS-232 to RS-
422 converter is required to communicate with the
3960 — which uses only RS-422.

Figure 11. Interconnection Diagram, Typical Test Setup
All mounting hardware should be of high
quality stainless steel — preferably of grade 316.
This will ensure high strength fasteners resistent to
corrosion.
All mounting hole patterns discussed in this
section are four holes 90 degrees apart at the
diameters noted unless otherwise mentioned.
Mechanically indexing to a home position
should not be required since the 3960 will return to
the last position at shut down when turned on again.
Refer to section 4 at the back of this manual
for additional details concerning these various
methods of mounting a 3960 to a pole, building, or
other type of structure.
The following paragraphs describe some of the
features of the 3960 related to the installation
process.
2.8 Installation Procedure
It is important to carefully plan for all cable
routing before starting an installation. In some
situations cable will have to be pulled through
conduit or other narrow places before adding a
connector to the end of a system cable. Any
through-wall holes may require weatherproofing.
Installing the 3960 is straightforward. It is only
necessary to mount the 3960 to a suitable base,
mate the cable connector to the system cable and
apply power. This assumes the other end of the
cable is properly connected to a source of power, a
tv monitor, a graphical user interface (GUI), and any
other required equipment. Figure 11 shows a basic
setup of the 3960 in a test setup as would be used
in a test facility. This diagram should give some idea
of a typical installation. Each installation site,
though, will have its own unique requirements.
2.8.1 Camera Module Rear Panel Features
Only two features appear on the rear panel
(figure 14) of the camera module of a 3960. One is
a Schrader valve for applying dry nitrogen to the
interior of the Camera assembly housing and the
other is a 20 psig (138 kPa) pressure relief valve.
2.8.1.1 Schrader Valve
A Schrader valve is functionally identical to
those used for car tires. But this valve should be
used only to introduce dry nitrogen to a camera.
During assembly cameras are purged of normal

3960 CAMERA
INSTALLATION AND OPERATION
room air (which typically has a high relative humid-
ity) by flowing dry nitrogen into the Schrader valve
and out the pressure relief valve. This relief valve
should be held open to aid in the flow of nitrogen
out of the camera.
This purging process removes moist room air
from inside the camera and provides an internal
relative humidity of five percent or less. A camera is
typically pressurized to 5 psig (34 kPa). Pressure
can be allowed to go below this — even down to
one or two pounds so long as the pressure does not
ever become zero. An occasional recharge of dry
nitrogen can be used to maintain pressure near 5
psig (34 kPa). If pressure continually drops it is an
indication of a slow leak. These pressure refer-
ences are gauge pressures (psig). They are relative
to the altitude above sea level at which they are
being measured.
2.8.1.2 Pressure Relief Valve
The pressure relief valve opens at about 20
psig (138 kPa). This relief pressure allows the 3960
to be taken to high altitude during transportation
without excess bleed off of dry nitrogen from the
camera housing. If the camera module should loose
some dry nitrogen during high altitude transporta-
tion (as indicated by a pressure reading below
about 5 psig) then some additional dry nitrogen may
be added to replenish the lost nitrogen.
This valve should be manually lifted off its seat
or pushed slightly to the side when it is desired to
flow dry nitrogen through the camera to purge
moisture laden atmospheric air from the camera
module.
Regularly applying pressure above 5 to 8 psig
(35 to 55 kPa) may cause seals to weaken and
leak.
2.8.2 16-pin Connector
This connector is attached to the 34 inch (86
cm) long cable that is permanently attached to the
base of the 3960. Table 6 lists pin functions for a
115 V ac version of the 3960 and table 7 lists
functions for a 24 V ac version. Note that five of the
pins are not used — although different pins are
used to apply the line (hot) lead of 115 V ac and
one line of the 24 V ac power. The camera model
number identifies whether it is configured for 115 V
ac or 24 V ac operation.
Figure 10 is the pin location diagram of this
connector. It is a view from the mating side of the
connector. This view is identical to the wiring view of
a mating connector (supplied) for the system cable
that plugs into this 3960 connector.
The connector supplied for the system cable
should not be installed until it is verified that the
cable can be pulled through any conduit or other
restricted passage on its way to the mounting
location of the 3960.
2.9 Preparation for Shipment and Storage
Maintain the 3960 storage environment within
a range of -34 to 74 °C (-29 to 165 °F).

3960 CAMERA INSTALLATION AND OPERATION
For shipment, package with enough foam
padding or other packing material to prevent dam-
age that can occur during shipping. The original
shipping carton is a good container if it has not
been damaged or subjected to excessive moisture.
For shipping to the factory by Common Carrier, use
the following address:
Cohu Electronics
3912 Calle Fortunada
San Diego, CA 92123-1827
Please contact the Customer Service Depart-
ment for a Return Authorization (RA) number before
sending any shipments to the factory:
or
858-277-6700 extension 261
Prominently display the RA number on the
outside of the shipping container(s) and on paper-
work contained inside. Give a brief description of
why the equipment is being returned and list the
symptoms of any problems being experienced with
the equipment.
3.0 OPERATION
Several GUI interfaces are available for use
with the 3960:
1. Win MPC (figure 19) is used to control a single
3960 during installation or maintenance operations.
This can be done either at a central shop facility or at
the site location of the 3960.
2. CAMS is used to control multiple 3960 systems
when an MPC Master Control Panel is being used as
the central control point.
3. NET Cams is used to control systems with multiple
3960 when the central control is a Net Cams Server.
This section of the manual describes use of
the WinMPC maintenance and setup GUI software.
3.1 Local Panel Control
If the 3960 has been connected through a
nearby Model 9300 Local Control Panel back to the
central control facility, it is possible to connect a tv
monitor to the Panel and control basic functions of
the 3960. A laptop PC running Windows would
connect to the RS-232 BNC connector on the front
of the panel for communications with the 3960. The
LOCAL/REMOTE switch on the 9300 must be set to
LOCAL to perform this local control.
The model 9300 local control panel can be
programmed for a site address. That address is
used for the site address — not the address of the
3960.
The system cable plugs into the 9300 and a
second cable then interconnects between the 9300
and the 3960. The 9300 becomes the site address.
3.2 Local Laptop PC Control
A local laptop PC running Win MPC software
can be used to connect to the 3960 and control a
full range of functions including the setting of its
address. This laptop can either connect through an
RS-232 connector on the front of an optional Local
Control Panel or it can connect directly to the 3960
RS-422 cable — in which case the RS-232 to RS-
422 converter is required.
3.3 WinMPC Installation Setup
Figure 20 is the home window of WinMPC. It is
from this window that other windows can be ac-
cessed. When Win MPC is used to set up the
3960, it must be isolated from all other 3960s (or
other addressable equipment) in the system. This
generally is no problem since the 3960 setup is
performed either at a test bench location or at the
actual 3960 site itself. If the address setting func-
tion of Win MPC were to be sent to multiple 3960s
they would all have identical addresses pro-
grammed into their memory. Since all addressable
equipment in a system must have a unique ad-
dress, this would result in an inoperative system.
Note: A separate operator’s manual is available for
the WinMPC software (Cohu manual No. 6X-1032.)
The information here describes initial use of
WinMPC for use with the 3960. Additional informa-
tion is available in the WinMPC manual. Also be
aware that the software may be updated more often
than this manual. Slight differences may be noted
with the version of WinMPC that is currently avail-
able for the 3960.

3960 CAMERA INSTALLATION AND OPERATION
3.3.1 Establishing Communications
Since each 3960 in the system (or optional
local control panel) must have a unique address, it
is probably best to set all addresses at a test bench
located at the central 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 duplica-
tions occur.
Before the address can be set or any other
setups made, it is necessary to establish communi-
cations with the 3960. The home window of Win
MPC provides the initial setup selections. Proceed
as follows:
1. Under the Special Functions menu area of the
Cohu - WinMPC (home) window, click on Camera
Setup. Anew window should appear titled Setup.
2. Under the Setup window set:
a. Receiver selections to iDome/iView/IView2 (this
is the series to which the 3960 belongs)
b.At the Comm area of the window:
i. Select the Port being used on the PC (Com1,
Com 2, Com 3, Com 4)
ii. Select a Baud Rate of 9600 (Click “Set Baud”)
c. At the Comm Mode area of the Window:
i. Select PC to MPC Receiver
d. At the Camera area of the window:
i. Select Day/Night (default)
ii. Under Video select NTSC or PAL, as appropri-
ate
e. Under the Pan/Tilt area of the window:
i. Select Var Speed P/T (default)
ii. Select a Max Pan Speed of 15 (default)
iii. Select a Max Tilt Speed of 15 (default)
f. Under the Pan/Tilt Background area select any
desired image type for the center pan/tilt area of the
home page.
g. Under the Set Elevation (0-10,000 ft) area of
the window:
h. Set Elevation for the elevation above sea level at
which the 3960 is to be installed. (This provides
calibration for the low pressure circuit)
i. Click on OK to exit the Setup window (or Cancel to
exit without making any changes).
3.3.2 Setting the 3960 Address
After initial setup, it is a good idea to allow Win
MPC to search for the existing address. This will
verify that communications has been established.
Click on the FIND button at the upper left of
the window. A pop-up window will appear while Win
MPC searches for all allowable 3960 addresses (1
to 223).
NOTE: Win MPC is intended to be connected to one 3960
at a time. If it were to be connected into a system of 3960s
and the Address Set Function used, all 3960s (or other
equipment) in the system would have their identifications
set to the same address.
