1. General
The LQ-200CL is a 4CCD line scan camera using four 2048 pixel line sensors mounted on a prism, for
the R, G,B and NIR channels. It operates with a 40 MHz pixel clock, resulting in a maximum line rate
of 19,048 lines per second.
The camera outputs digital data in 4 x 8 bits or 4 x 10 bits format via Camera Link. The camera is
configured by software through the serial communication port of the Camera Link interface, or via
RS-232C through a 12-pin Hirose connector.
The camera accepts M52 mount or F-mount lens.
The LQ-200CL is a suitable camera for various applications such as inspection of fruits,
vegetables ,circuits boards or electronic/mechanical parts, as the NIR image can catch scratches or
blemishes on object surfaces which the RGB color image cannot find.
The latest version of the operation manual can be downloaded from www.jai.com .
The latest camera control tool for the LQ-200CL can be downloaded from www.jai.com .

*1) Note: Rear protrusion on M52 mount lens must be less than 13mm.
*2) Note: When a CameraLinkTM cable is connected to the camera, please do not excessively tighten
screws by using a driver. The CameraLink receptacle on the camera might be damaged.
For security, the strength to tighten screws is less than 0.291 Newton meter (Nm).
Tightening by hand is sufficient in order to achieve this.
*3) Note: The depth of mounting hole is 5.5mm ± 0.2mm. If the longer screws than 5.7mm are used,
they may damage the circuit board inside.

5.3. Input and output circuits
5.3.1 Trigger input
The External Trigger signal can be applied
either through the Camera Link connector or
at pin 10 of the 12-pin Hirose connector. The
command to change this setting is TI (Trigger
Input). TI=0 for Camera Link connector
(factory default) and TI=1 for 12-pin Hirose
connector. The input via the 12-pin Hirose
connector is AC coupled.
To allow long pulses, which may be required
when using the Pulse Width Control (PWC)
trigger mode, the input circuit is designed as
a flip-flop circuit. The leading and trailing
edges of the trigger pulse activate the circuit.
The trigger input polarity can be changed by
the command TP. At the 12-pin Hirose connector the External Trigger input is 4V ± 2V (TTL). It can
be changed to 75 ohm termination by a DIP switch setting (SW 1).
5.3.2 EEN / XEEN output (Exposure ENable)
This output corresponds to the exposure
(accumulation) time of the camera. It works
together with all operation modes. It is,
however, not active when the test pattern
function is enabled.
The EEN signal is available at the Camera
Link connector and at the 12-pin Hirose
connector at the same time.
At the Camera Link connector this signal has
positive logic.
At pin 9 of the 12-pin Hirose connector the
signal has negative logic, and is therefore
named XEEN. The output circuit is a 75 ohm
complementary emitter follower. The
circuit is powered from the 5V supply,
resulting in an output level of more than
4V. It is not terminated.
