Description
The next generation of Piranha line scan cameras has arrived with more power, more
speed and more resolution than ever before. The Piranha 3 camera family takes imaging
to a new level with eight outputs running at 40MHz and either 8k or 12k resolutions. The
large number of pixels and fast line rates specifically meet the throughput demands of flat
panel inspection (Gen7 and Gen8), printed circuit board inspection, and multi-camera
web inspection. With this large resolution and high speed, these cameras can inspect
more panels in the same amount of time than ever before
Applications
The Piranha 3 family is ideal for applications requiring high speed, superior image
quality, and high responsivity. Applications include:
Flat panel display inspection
Printed circuit board inspection
Parcel sorting
Multi-camera web inspection
High performance document scanning
High throughput applications
Models
The Piranha 3 cameras are available in the following models.

Camera Hardware
Interface
2.1 Installation Overview
When setting up your camera, you should take these steps:
1. Power down all equipment.
2. Follow ing the manufacturer’s instructions, install the frame grabber (if app licable). Be
sure to observe all static precautions.
3. Install any necessary imaging software.
4. Before connecting power to the camera, test all power supplies. Ensure that all the
correct voltages are present at the camera end of the power. Power supplies must
meet the requirements defined in section 2.2.2 Power Connector.
5. Inspect all cables and connectors prior to installation. Do not use damaged cables or
connectors or the camera may be damaged.
6. Connect Camera Link and power cables.
7. After connecting cables, apply power to the camera.
8. Check the diagnostic LED. See 2.2.1 LED Status Indicator for an LED description.
You must also set up the other components of your system, including light sources,
camera mounts, host computers, optics, encoders, and so on.
2.2 Input/Output Connectors and LED
The camera uses a:
•Diagnostic LED for monitoring the camera. See LED Status Indicator in section 2.2.1
LED Status Indicator for details.
•6-pin Hirose connector for power. Refer to section 2.2.2 Power Connector for details.
•High-density 26-pin MDR26 connector for Camera Link control signals, data signals,
and serial communications. Refer to section
This installation
overview assumes you
have not installed any
system components yet.

Figure 3: Piranha 3 Input and Output Connectors
WARNING: It is extremely important that you apply the appropriate voltages to your camera.
Incorrect voltages will damage the camera. See section 2.4 for more details.
2.2.1 LED Status Indicator
The camera is equipped with a red/ green LED used to display the operational status of
the camera. The table below summarizes the operating states of the camera and the
corresponding LED states.
When more than one condition is active, the LED indicates the condition with the highest
priority. Error and warning states are accompanied by corresponding messages further
describing the current camera status.

Color of Status LED
Meaning
Flashing Green
Camera initialization or executing a long command (e.g., flat field
correction commands ccp or ccf)

2.2.2 Power Connector
Figure 4: Hirose 6-pin Circular Male—Power Connector
The camera requires a single voltage input with a +12V to +15V operating range (+11V to
+16V absolute maximum range). The camera meets all performance specifications using
standard switching power supplies, although well-regulated linear supplies provide
optimum performance.
WARNING: When setting up the camera’s power supplies follow these guidelines:
•Protect the camera with a fast-blow fuse between power supply and camera.
•Do not use the shield on a multi-conductor cable for ground.
•Keep leads as short as possible to reduce voltage drop.
•Use high-quality linear supplies to minimize noise.
•Use an isolated type power supply to prevent LVDS common mode range violation.
Note: Performance specifications are not guaranteed if your power supply does not meet
the +12V to +15V requirements.
WARNING: It is extremely important that you apply the appropriate voltages to your
camera. Incorrect voltages will damage the camera. Protect the camera with a fast-blow
fuse between power supply and camera.
We offer a power supply w ith attached 6’ power cable that m eets the Piranha 3 cam era’s
requirements, but it should not be considered the only choice. Many high quality supplies
are available from other vendors. Teledyne DALSA assumes no responsibility for the use
of these supplies.
Visit the www.teledynedalsa.com Web site for a list of companies that make power
supplies that meet the camera’s requ irem ents. The com panies listed shou ld not be
considered the only choices.

2.2.3 Camera Link Data Connector
Figure 5: Camera Link MDR26 Connector
A note concerning the length of the Camera Link cables
The length of the cables over which data can be transmitted without loss depends on the
data rate and on the quality of the cables.
The camera is tested using a recognized brand of cable with a length of 5 meters. Data
transmission is not guaranteed if you are using a cable greater than 5 meters in length.
Camera Link Configuration
The Camera Link interface is implemented as a Medium or Full Configuration in the
Piranha 3 cameras. Refer to section 3.3.1 Setting the Camera Link Mode for details on
setting the Camera Link configuration.

Input Signals, Camera Link
The camera accepts control inputs through the Camera Link MDR26F connector.
The camera ships in internal sync, internal programmed integration (exposure mode 2).
EXSYNC (Triggers Line Readout)
Line rate can be set internally using the serial interface. The external control signal
EXSYNC is optional and enabled through the serial interface. This camera uses the falling
edge of EXSYNC to trigger line readout. Section 3.2.1 Exposure Mode, Line Rate and
Exposure Time details how to set frame times, exposure times, and camera modes.
Output Signals, Camera Link
These signals indicate when data is valid, allowing you to clock the data from the camera
to your acquisition system. These signals are part of the Camera Link configuration and
you should refer to the Camera Link Implementation Road Map, available here, for the
standard location of these signals.

•The camera internally digitizes 12 bits and outputs 8 MSB or all 12 bits depending on
the cam era’s Cam era Link operating mod e. Refer to section 3.3.1 Setting the Camera
Link Mode for details on setting the Camera Link configuration.
•For a Camera Link reference refer to Appendix A on page 71.
IMPORTANT:
This camera’s data
should be sampled on
the rising edge of
STROBE.
