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.

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.

6. Functions and Operation
6.1. Basic functions
Fig.9 Signals flow
The LQ-200CL uses four high-performance CCD line scan image sensors mounted on a prism block.
During exposure, the incoming light is converted to electrons (electric charge) in the photodiodes
(active pixels). The transfer gate controls the transfer of charge from photodiodes to the shift
register. Activating the transfer gate terminates the exposure cycle, transfers the charge to the
Horizontal Shift Register (2-phase buried channel CCD shift register) and starts a new exposure
cycle. The line is subsequently read out in a single sequence starting with pixel 1.
The exposure time is normally the same as the cycle time (in No-Shutter mode). By using the
Exposure Control Gate (in Shutter-Select or Pulse Width Control trigger modes) the exposure time
can be individually set to be shorter than the cycle time (the inverse of line rate). This also allows
a fixed exposure time, independent of the line rate. In the LQ-200CL the exposure time can be set
individually for all four channels.

6.2.1 No-Shutter mode with internal trigger
In this mode the camera does not accept an external trigger signal, as the line rate is generated
from an internal clock (user programmable, command LR). The exposure time is directly
proportional to the line rate (Texp = 1/line rate). This mode is used when there is no external
trigger signal available, and the speed of the object is fixed or can be pre-determined.
The line rate can be varied from 1 line period (L) to 1024L in 1 clock (25ns) steps (19 kHz down to
18 Hz). When using this mode, a special function called “One-push auto line rate” is available.
This mode automatically maintains a constant output level by changing the line rate. The line rate
is automatically adjusted in order to maintain sensitivity without reducing the S/N ratio.
To use this mode:
Set function Trigger mode, No-Shutter TR=0
Trigger origin, internal TG=0
Line rate LR=2100 to 2150400
(52.5 µs to 53.8 ms in 25ns increments)
Optional functions when using this mode:
One-push auto line rate AR=0
Auto line rate reference AL=0 to 1023
One-push white balance WB

Important Note
Only gain-based one-push white balance function (WB) is available with this mode.

6.2.2 No-Shutter mode with external trigger
In this mode, the exposure time is directly proportional to the line rate. The line rate is generated
externally by a trigger signal. This mode is used when an external trigger signal available, e.g.
from an encoder, and the scan rate can be controlled by this signal. The camera can accept an
external trigger through the Camera Link connector or though the 12-pin Hirose connector.
To use this mode:
Set function Trigger mode, No-Shutter TR=0
Trigger origin, external TG=1
Trigger input TI=0 or 1
Important note:
When the one-push white balance has been initiated and the rear panel LED shows orange, the
camera must receive continuous external trigger pulses corresponding to the frequency and
duty cycle used in the application.
Only gain-based one-push white balance function (WB) is available with this mode
The minimum trigger interval is 52.6μs.

6.2.3 Shutter-Select mode with internal trigger
This mode allows the user to have full control of the line rate and the exposure time individually,
by programming separate timing generators. Subsequently, the camera does not accept an external
trigger signal in this mode.
To use this mode:
Set function Trigger mode, Shutter-Select TR=1
Line rate LR=52.6μs to 53.683ms
Trigger origin, internal TG=0
Individual R, G and B exposure EI=0(individual)
EI=1(tracking with G)
Programmable exposure PER/PEG/PEB/PEIR=2 to 2150400 (in 25ns
steps)
Important note:
If using individual exposure, the EEN signal represents the channel with the longest exposure
time
The longest shutter operation is the same as the set trigger interval.
If one-push auto white balance is used, using the shutter (command AH) or using the gain
(command AW) depends on applications. If the auto white balance switch located on the rear
panel is used, only the gain is effective.

6.2.4 Shutter-Select mode with external trigger
This mode allows the user to have full control of the exposure time, by programming a timing
generator, while the line rate is controlled by an external trigger signal. The camera can accept
an external trigger through the Camera Link connector or though the 12-pin Hirose connector.
To use this mode:
Set function Trigger TR=1
Trigger origin, external TG=1
Individual R, G and B exposure EI=0(individual)
EI=1(tracking with G)
Programmable exposure PER/PEG/PEB/PEIR=2 to 2150400 (in 25ns
steps)
Important note:
If using individual exposure, the EEN signal represents the channel with the longest exposure time
The trigger interval is more than 52.6μs.
If one-push auto white balance is used, using the shutter (command AH) or using the gain
(Command AW) depends on applications. If the auto white balance switch located on the rear
panel is used, only the gain is effective.
When the one-push white balance has been initiated and the rear panel LED shows orange, the
camera must receive continuous external trigger pulses corresponding to the frequency and
duty cycle used in the application.
The maximum trigger period is the interval of the input trigger.

6.2.5 Pulse Width Control (PWC) mode
In this mode, the user has full control of both the line rate and the exposure time of each line via
the External Trigger input.
At the falling edge of the External Trigger signal, the exposure is initiated, and at the rising edge
the exposure is terminated and read out. The camera can accept an external trigger through the
Camera Link connector or though the 12-pin Hirose connector.
To use this mode:
Set function Trigger mode, PWC TR=2
Important Note:
Possible pulse width:
TTL input via 12P 52.6μs
Camera link input 52.6μs
One-push white balance by gain setting only.
The trigger interval is more than (Exposure period + 52.6μs).
When the one-push white balance has been initiated and the rear panel LED shows orange, the
camera must receive continuous external trigger pulses corresponding to the frequency and
duty cycle used in the application.
