6110 CAMERA
INSTALLATION AND OPERATION
Preliminary 3a 4-14-05
1.0 GENERAL DESCRIPTION
This introduction briefly describes the overall
characteristics of the Model 6112 Camera
(figure 1) related to its installation and operation.
1.1 Electrical Characteristics
A model number interpretation diagram
appears in figure 4. That diagram shows the
various basic configurations of the Camera. Table
1 lists the specifications.
1.1.1 Sensor Characteristics
The sensor is a 1/2-inch (8 mm) 4:3 aspect
ratio package. It is a monochrome CCD interline
transfer progressive scan sensor. The glass
faceplate is 0.75 mm thick with a reflective index
of 1.5. There are 1360 horizontal and 1024
vertical active pixels. Pixels are square: 4.65 µm
x 4.64 µm.
Figure 2 shows the optical black pixels
surrounding the active area. Figure 3 graphs the
spectral sensitivity of the sensor. Note that this
is the sensitivity curve of the sensor itself — not
including any lens or light source.
The Camera obtains enhanced sensitive and
low dark current through use of a Hole Accumu-
lation Diode (HAD) sensor.
The sensor offers an electronic shutter with
variable charge store time so that a full frame
image can be obtained without a mechanical
shutter.
1.1.2 IEEE-1394a Connector (6-pin)
This connector is the six pin version of a
1394a connector. Two pins are used to carry
power to the camera. The camera derives operat-
ing power for video and processing control from
this connector. (Strobe circuits obtain dedicated
power from the RJ-45 connector.)
1.1.3 RJ-45 10 Wire Connector
Only seven of the 10 pins on this connector
are used: two for the trigger input to capture
scenes, four to strobe external scene lighting
circuits, and one to provide Vcc input for these
strobe circuits. These are opto-isolate circuit
functions. Power for these circuits is provided

1.2 Mechanical Characteristics
The 6110 has optical and mechanical inter-
faces identical to the Cohu model 2600 camera.
It can be mechanically substituted in place of a
2600 camera.
Dimensions are shown in figure 5. Note that
these dimensions do not include the adjustable
CS-mount. Also note that the base of the Camera
is dimensioned both with and without the mount-
ing block. It can be removed if desired.
The CS-mount lens adapter threads into the
front of the housing. Adding the 5-mm extension

ring (provided) allows C-mount lenses to be used
with the Camera.
Two connectors are located at the rear
panel. One is an IEEE-1394a six-pin connector
that carries video/control input power and the
other is an RJ-45 10-pin connector to support the
auxiliary functions of triggering and strobing. The
RJ-45 has power input on pin 7 to drive the
strobe stages. Triggering is directly driven by the
externally applied trigger signal.
The camera can be mounted in four ways:
1. By the lens
2. To the top of the case
3. Directly to the bottom of the case, and
4. To a removable mounting block on the bottom of
the case.
The top of the case has a single 1/4-20 hole
for mounting purposes.
The bottom of the case has a pair of
threaded 6-32 x 0.086-inch deep holes for direct
mounting or these mounting points can be used

to attach the removable mounting block which
then provides two 1/4-20 mounting holes.
1.2.1 CS-mount or C-mount Lens
Use a manual-iris lens compatible with the
1/2-inch sensor in the camera. Either a CS-mount
lens or a C-mount lens can be used. Use of a C-
mount lens will require that the 5-mm extender
supplied with the Camera be threaded onto the
C-mount lens before it is then threaded onto the
CS-mount adapter.
2.0 INSTALLATION
This section covers the general require-
ments of installing the camera including cabling
and power requirements. 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 Camera. Refer to table 2 for a summary of
key points to remember about installing and
using the Camera.
Section 4 of this manual covers Receiving
Inspection, Static Precautions, and Return Ship-
ment to the Factory.
2.1 Equipment Supplied
Table 3 lists the equipment supplied with the
basic camera model number. Other items may
be supplied if they wereordered with the camera.
2.2 Equipment Required but Not Supplied
Table 4 is a list of equipment required to
make the camera operational in a minimum
configuration. Other items may be required
depending on the application.
2.3 Cabling Requirements
The rear panel provides two connectors for
interconnections with other equipment.
As a minimum, the IEEE-1394a connector
must be used. It provides several functions
including operating power to the camera, picture
data out to the viewing PC, and control functions
for the camera.
The RJ-45 connector offers two auxiliary
functions that may not be required. This is an
opto-isolated port and thus requires its own
supply power on pin 7. It has a trigger input to
capture a scene image and four programmable
strobe outputs to “fire” strobe lights during the
integration period of the sensor.
2.3.1 IEEE-1394a Cable
Installation cables for IEEE-1394a are best
obtained from a reliable cable manufacturer and
not built on-site. Use only a cable of the highest
quality. All six wires are required since the cam-
era draws its operating power from this cable.

Table 2. Key Points to Remember
ITEM KEY POINTS
STROBE OUTPUTS
1 Using the strobe outputs requires a cable with an RJ-45 connector
2 Using the strobe outputs requires that power be supplied to the RJ-45 connector
3 Strobe outputs must be current limited to protect the internal emitter follower drive transistor
4 Strobe outputs are optoisolated from other camera circuits
5 Start & stop times on the strobe setup window must be within the frame time being used
6Shuttering impacts the strobe times that can be set. When the sensor is being shuttered, the integration
interval during which time the scene is obtained occurs during the last part of the vertical interval
TRIGGER INPUT
7Externaltriggering for scene capture can be implemented either through the software interface or by
ahardwire connection on the RJ-45 connector
8 Hardwire triggering does not use the Vcc power input on the RJ-45 rear panel connector
POWER INPUTS
9 Power for camera video and control circuits is supplied via the 1394a cable (a 6-wire cable)
10 When strobe outputs are to be used, power must also be supplied to the RJ-45 auxiliary connector
OP E RATING C ONS ID E R ATIONS
11 Selecting some of the control functions requires stopping the camera (stop is equivalent to pause)
12 At full resolution, maximum frame rate is 4 frames per second
13 For setup and adjustment purposes, select the Draft mode for 12 frames per second operation
14 A tif or bmp image of the scene can be saved to an external hard drive or other device
For test bench cables, though, it is possible
to buy RJ-45 10-pin cable connectors and use a
punch-down tool to install the required wires onto
the connector.
2.3.2 RJ-45 Auxiliary Cable
Only seven of the 10 pins of this connector
are used. One pin is input power for the strobe
outputs, four are strobe output lines, and two
provide trigger input for scene capture. Depend-
ing on the length of this cable run and the noise
environment of the installation it may not require
overall shielding or shielding of the trigger lines.
Figure 7 is the wiring diagram for a cable show-
ing overall shielding for longer runs.
2.4 Power Requirements
Operating power for the camera must be
supplied via the 1394a cable. Power for the
strobe outputs must be supplied to the RJ-45
connector if they are to be used.
2.4.1 Power Over 1394a
The IEEE-1394a specification provides for
devices to obtain operating power over a 1394a
cable (6-wire type). The 6100 makes use of this
feature so the device it is connected to must
provide this power. Powered 1394a sources
must be capable of supplying any voltage from 8
to 30 V dc.
The Camera requires 12 V dc from the
1394a cable at less than 3 watts
If the Camera is to be operated with Viewer
software running on a laptop computer it is likely
that this computer will have a 4-pin (non-pow-
ered) 1394a connector. In this case an external
power supply adaptor will be required to intercon-
nect between the 4-pin 1394a connector on the
laptop and a 6-pin 1394a cable (powered type) —
which then provides this adapter voltage to the
Camera. These adapters are spcifically made for
1394a applications.
2.4.2 Strobe Power via RJ-45
If power is required to the RJ-45 auxiliary
connector, it is applied to pin 7. This power is

86X-1050
6110 CAMERA INSTALLATION AND OPERATION
Preliminary 3a 4-14-05
labeled +Vcc on the illustrations because the
actual voltage applied depends on the circuit
externally connected to the strobe outputs. A
typical input range would be from 3.3 V dc to 15 V
dc. The strobed outputs are common collector
(emitter follower) circuits. Each output is specified
to provide a maximum of 35 mA in continuous
operation. An external 100 ohm series resistor is
shown in figure 9 to protect the internal drive
transistor from an accidental short to ground. This
assumes a 5 V dc input for Vcc on pin 7.
2.5 Mounting Requirements
The dimensions shown in figure 5 related to
mounting the Camera. The Camera can be
mounted in four different mounting configurations:
1. By the lens (being careful to ensure that the
attached cables do not provide excessive pressure
on the camera)
2. By the single 1/4-20 threaded hole on the top of
the case
3. By the two 6-32-0.086 threaded holes on the
bottom of the case
4. By two 1/4-20 threaded holes on a mounting
adapter that can be installed on the bottom of
the case. The Camera is typically shipped with
this mounting block installed.
The following paragraphs describe some of
the features of the Camera related to the instal-
lation process.
2.6 Installation Procedure
Prior to installing the camera it may be
necessary to prepare an auxiliary interface if
the triggering and strobe lines on the RJ-45
connector are to be used. See figures 6 and 7.
The camera can only be operated by
Viewer software running on a PC interfaced via
a IEEE-1394a cable.
Installing the Camera is straightforward. It
is only necessary to mount the Camera to a
suitable base, install the lens, attach the
cable(s), apply power, and operate it using the
Viewer software.

Table 4. Item Typically Required
But Not Supplied
Table 5 lists the two cables that interconnect
with the Camera rear panel. The RJ-45 cable is
required only if external triggering or strobe
outputs are to be used.
The following is a general description of the
typical installation procedure for a camera.
1. Prepare the auxiliary interface and cable for the
RJ-45 connector if this is required. Use of the
strobe functions requires that power be supplied to
the opto-isolator stages in the camera dedicated to
the strobe circuits. (The trigger input directly drives
the cathode and anode of a photodiode in the
Camera and does not use the Vcc input of the
strobe circuits.)
2. Prepare the PC by verifying that it has an IEEE-
1394a port with power output and also the appro-
priate software to communicate with the camera
3. Install a CS- or C-mount lens on the camera
suitable for use with a 1/2-inch sensor. It may have
to be mechanically back focused once the camera
is operational. Back focus will have been factory
set using the lens that the Camera was ordered
with, but if the Camera was not ordered with a
lens then a typical lens would have been used. A
field supplied lens may have a slightly different
characteristic and thus require back-focusing of
the lens mount adapter. This procedure is de-
scribed in section 2.8.3.
4. Mount the camera
5. Connect the 1394a and if required the auxiliary
cable
6. Obtain a picture from the camera. This requires
use of the Viewer GUI software operating on a PC.
See section 3.0 for Operating instructions.
7. Adjust mechanical back focus by rotating the
lens and C-mount if required. See section 2.8.3.
8. Make any other adjustments to focusing and
mechanical alignment if required.
9. Perform an operational test of the camera
functions. Sections 2.8.1 through 2.8.4 provide
additional installation instructions about the rear
panel connectors, the back focus adjustment for
the lens, and other features.
