1Introduction
1.1 What’s In this Manual
This manual describes the receiving, unpacking and inspection of your LC3000
series camera. Included is a operational overview that defines the camera
operation and the controls provided. Guidance is provided for the installation,
setup and initial operation of your LC3000 camera.
1.2 Purpose
To provide machine vision system engineers and technicians a definitive guide
for integrating LC3000 series cameras into their specific machine vision
application.
1.3 Product Overview
The LC3000 series cameras are designed for linear line scan image capture
applications. 512, 1024 and 2048 pixel line scan image capture is offered at 10,
or 20 megapixels/second depending on the camera model selected. Each camera
uses a PerkinElmer P-series photodiode linear array with 14mm pixel pitch at a 14
mm aperture. This provides a 54dB dynamic range over a spectral range of 350 to
1000 nm. All camera control functions are selected by corresponding DIP
switches. Digital I/O is provided as differential RS-422. The video output is
differential analog.
1.4 Functional Description
The LC3000 series cameras incorporate high performance, high resolution line
scan image sensors. (PerkinElmer Optoelectronics Imaging Systems parts
RL0512PAG, RL1024PAG, or RL2048PAG) featuring pinned photodiode pixels.
Each photodiode converts incident light into discrete charge packets that are
converted to an analog voltage.
The analog voltage is processed as a single channel sampled and held raster order
analog video data signal. Analog processing circuitry provides adjustable gain
and offset levels allowing the accommodation of unique lighting requirements.

3Receiving and Inspecting Your Camera
3.1 Unpacking Your Camera
Inspect the received shipping container for any damage. If a shipping container
shows visible signs of damage, it should be retained until all of the contents have
been checked for completeness and absence of damage. Unpack the received
shipping container and account for each item listed on the accompanying packing
list. Visually inspect each item for absence of damage. In the event of damage,
notify the shipper and the PerkinElmer shipping department. Retain all shipping
materials for shipper inspection.
Your first LC3000 shipping container in accordance with the enclosed packing
list should contain the following:
1. LC3000 camera in static resistant envelope with unbroken seal.
2. Users Manual
3. Tripod Mount
3.2 Customer Supplied Components
The following are components, not supplied with the camera, that are required for
installation and operation of the camera in your particular machine vision
environment.
1. Camera Lens + Extender (Available by contacting PerkinElmer)
2. Camera mounting hardware (Tripod mounting block included)
3. PC with Frame Grabber and digital I/O
4. Power Supply
5. Interface Cable (Available by contacting PerkinElmer)
6. Web illumination source
7. Web speed and light control.
This is not a complete list of items that may be required for your specific
application, but represents a minimum required to verify camera operation.
Note: The majority of the customer supplied items are peculiar to each installation and
may require custom fabrication. Guidelines for fabrication are provided in section
6.2 on page15.

4Camera Operation Overview
The camera operation is a 2 stage process that consists of exposure and data
output transfer. This process operates the same regardless of mode. The only
differences are the events that initiate exposure and data output transfer.
The LC3000 series cameras offer 4 exposure modes for maximum flexibility to
capture image data in a variety of applications.
4.1 Camera Exposure Modes
The following exposure modes are provided:
·Master Mode
·Slave Mode
·Slave Mode (Alt 1)
·Slave Mode (Alt 2)
The camera modes are selected by DIP switches accessible on the back of the
camera. For a definition of mode selecting switch positions see section 6.4.1on
page18.
Note: If the mode is changed while the camera is operating, the camera must be
powered down and restarted for the mode change to take effect.

PerkinElmer Optoelectronics 6
4.1.1 Master Mode
The master mode is a stand-alone operating mode that requires only DC power
for operation. Master mode is selected on the bank of DIP switches on the back of
the camera. For mode selection see section 6.4.1 on page 18.
Figure 3Master Mode Timing
The exposure time in master mode is determined by the line period that is fixed at
N+41 clock cycles, where N is the number of pixels. See Table 1on page 8for
line period definition
4.1.1.1 Data Output
The analog video is output together with three synchronization signals: Camera
Clock (CCLK), Line Enable (LEN) , and Camera Line Transfer (CLT). The
falling edge of the internally generated CLT signal indicates the start of a line
readout sequence and may be used by the user’s system for controlling strobes,
shutters or other accessories. The LEN signal brackets the valid analog video that
is output in synchronization with the CCLK. LEN goes high 1 CCLK period
before the first valid pixel and goes low 1 CCLK period prior to the last valid
pixel.
4.1.2 Slave Mode
The slave mode allows the synchronization of the camera operation with a user
generated master clock MCLK and a user controlled exposure period. Slave mode
is selected on the bank of DIP switches on the back of the camera. For mode
selection see section 6.4.1on page 18. When operating in the Slave Mode, the
user supplies LR (Line Reset), LT (Line Transfer) and MCLK (Master clock)
signals. The MCLK may be selected between 20 kHz to the maximum clock rate
allowed for the selected camera. In this mode, the camera output signals CCLK,
CLT and LEN are synchronized to MCLK to assure a locked video output. For
Slave mode timing, see Figure4.
