INSTALLATION AND OPERATION
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 Accumu­lation 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 operat­ing 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
6X-1050
from outside the camera to maintain complete isolation from the other camera circuits.
1.2 Mechanical Characteristics
The 6110 has optical and mechanical inter­faces 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 mount­ing 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
4
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

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 C­mount 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 require­ments 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 Ship­ment to the Factory.

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 cam­era draws its operating power from this cable.

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 adjustm ent 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. Depend­ing 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 show­ing 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.
6X-1050
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-pow­ered) 1394a connector. In this case an external power supply adaptor will be required to intercon­nect 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

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 instal­lation 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.
