1. General

The AT-200CL is a digital 3CCD progressive scan RGB color camera. It employs three 1/1.8
inch 1628(h) x 1326(v), 2 Megapixel CCDs and it runs 20 frames per second in full resolution
mode. The AT-200CL has a Camera Link® interface and its output can be either 8-bit through a
Camera Link Base configuration or 10-bit or 12-bit through a Camera Link Medium
configuration. JAI developed a new 1/1.8-inch compact F4.0 prism optical system and in
combination with a linear color matrix, the AT-200CL provides a higher fidelity of color
reproduction. The AT-200CL also incorporates a shading circuit, gamma correction circuit and
knee correction circuit to provide high picture quality. Functions like partial scanning and
vertical binning allow higher frame rates.

6. Mounting holes 8 x M3 depth 5mm for tripod mount plate or direct installation *3)

*1) Note: Applicable C-mount lens should be designed for 3-CCD cameras. Rear protrusion on

C-mount lens must be less than 4mm.

Be advised: when using a lens with the iris diaphragm fully open, vignetting on corners

may occur.

*2) Note: When a Camera Link® cable is connected to the camera, please do not excessively

tighten screws by using a driver. The Camera Link® 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 tripod adapter plate MP-41 can be used.

6. Input and output circuits

This chapter introduces the basic diagram and bit allocation of digital output.

6.1. Iris video output

This signal can be used for lens iris control In Continuous
and RCT modes. The signal is NUM luminance signal and
passes through the gain circuit. However, due to reversed
compensation applied, the gain settings do not influence
this signal. The iris video output is 0.7 V p-p from 75 
and without sync. This signal is always output except EPS
and PWC modes.

Fig. 7. Iris video output.

6.2. Trigger input

When TI=1, the trigger input is on pin #10 on
the 12-pin connector. The input is AC coupled.
To allow a long pulse width, the input circuit
is a flip-flop, which is toggled by the negative
or positive differentiated spikes caused by the
falling or rising trigger edges.
The trigger polarity can be changed by TP=1.
Trigger input level is 4 V 2 V. It can be
terminated by SW600 : ON for 75. OFF for
TTL. The trigger inputs can be changed to
Camera Link. (TI=0 for CL)

6.3. XEEN output

XEEN is found on pin #9 on 12-pin HR connector.
The output circuit is 75  complementary
emitter followers. Output level 3 V from 75.
(No termination).
When the open collector is used, the maximum
current is 120mA. However, if the current of
more than 50mA is flowed, it is necessary to use
bigger diameter wires for connecting pin#8 and

9. In case of narrower wires, due to its
resistance, it may not work properly.

This output can be changed to Open collector
signal by SW100.

EEN is found in Camera Link. It is high during
exposure.

Fig.9. EEN output

6.4. Digital output interface (Camera Link® interface)

The video output is Camera Link with 3 x 8 bits RGB video placed in a base configuration, or 3
x 10 bits or 3 x 12 bits RGB placed in a Camera Link medium configuration. The digital output
signals follow the Camera Link standardized multiplexed signal output interface. The Camera
Link output driver is NS type DS90CR285MTD.
The data bits from the digital video, FVAL, LVAL, DVAL and EEN are multiplexed into the
twisted pairs, which are a part of the Camera Link. Trigger signals and the serial camera
control are fed directly through its own pairs. The trigger input can also be TTL on the 12-pin
connector.
For details of the Camera Link® standard, visit the AIA web site www.machinevisiononline.org.

6.4.1 Camera Link® bit allocation
The AT-200CL outputs an RGB signal via Camera Link. A 3 x 8-bit signal is allocated via a Base
configuration through port 1, while a 3 x 10-bit or 3 x 12-bit signal is allocated via a Medium
configuration through both port 1 and port 2.

On the next page, there is bit allocation table.

7. Functions and Operations

7.1. Basic construction

A 32-bit micro processor controls all functions in the AT-200CL camera. The CCD sensor
output is normalized in CDS and preamplifiers. The signals are then digitized to 14 bits.
Digital gain control, color matrix, look-up tables and setup can do signal processing in 14 bits
before the signal is converted to a 12-, 10- or 8-bit Camera Link signal.

7.2. Main functions

7.2.1 Partial scan (SC)

The partial scanning function uses the middle of the image vertically to achieve faster frame
rates. This is very useful when capturing and inspecting an image which does not require the
full height. The AT-200CL has 4 types of pre-set partial scan modes: 2/3, 1/2, 1/4 and 1/8.

Fig.13 Partial scan (pre-set)

In addition to pre-set partial scan modes, the AT-200CL has a variable partial scan mode. The
start line can be set from the 1st line to 1236th line and the end line can also be set from the
1st line to the 1236th line. In actual use, the start line should always be set smaller than the
end line and the end line should be larger than the start line. For instance, if the end line is
set at 1236, the start line should be 1235 or smaller. If the start line is set at 1, the end line
should be set at 2 or larger.
