Description
The next generation of Piranha line scan cameras has arrived with more power, more
speed and more resolution than ever before. The Piranha3 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 Piranha3 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 Piranha3 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. Following the manufacturer’s instructions, install the frame grabber (if applicable). 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 2.2.3 Camera Link Data Connector for
details.
This installation
overview assumes you
have not installed any
system components yet.

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.

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.
DALSA offers a power supply with attached 6’ power cable that meets the Piranha3
camera’s requirements, but it should not be considered the only choice. Many high
quality supplies are available from other vendors. DALSA assumes no responsibility for
the use of these supplies.
Visit the www.dalsa.com Web site for a list of companies that make power supplies that
meet the camera’s requirements. The companies listed should not be considered the only
choices.

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 DALSA Camera Link Implementation Road Map, available at
http://vfm.dalsa.com/, for the standard location of these signals.
Clocking Signal Indicates
LVAL (high) Outputting valid line
DVAL (high) Valid data
STROBE (rising edge) Valid data
FVAL (high) Outputting valid frame
• The camera internally digitizes 12 bits and outputs 8 MSB or all 12 bits depending on

twSYNC The minimum low width of the EXSYNC pulse when
not in SMART EXSYNC mode.
100
twSYNC(SMART)
*
The minimum low width of the EXSYNC pulse when
in SMART EXSYNC modes to guarantee the
photosites are reset.
3,000
twSYNC_INT The minimum width of the high pulse when the
“SMART EXSYNC” feature is turned off
100
twSYNC_INT
(SMART) *
Is the integration time when the “SMART EXSYNC”
feature is available and turned on. Note that the
minimum time is necessary to guarantee proper
operation.
3,000
tLINE PERIOD
(t LP)
The minimum and maximum line times made up of
tTransfer, tREADOUT plus tOVERHEAD to meet
specifications.
53,190 (12k)
106,382 (8k)
tTransfer The time from the reception of the falling edge of
EXSYNC to the rising edge of LVAL when pretrigger
is set to zero. Pretrigger reduces the number of clocks
to the rising edge of LVAL but doesn’t change the
time to the first valid pixel. If the fixed integration
time mode of operation is available and selected then
the integration time is added to the specified value.
3,725 ±25
twFixed Int. Fixed Integration Time mode of operation for variable
exsync frequency.
800
tREADOUT Is the number of pixels per tap times the readout clock
period. Pretrigger = 0.
38,400 (12k)
25,600 (8k)
tOVERHEAD Is the number of pixels that must elapse after the
falling edge of LVAL before the EXSYNC signal can be
asserted. This time is used to clamp the internal
analog electronics
425±25
thPR Applies when the PRIN exposure control feature is
enabled . The PRIN signal must be held a minimum
time after the EXSYNC falling edge to avoid losing the
