1. Outline
TLC-7500CLD is the color line scan camera with 3-lines of 7500-pixels CCD image sensor and has the following
features.
2. Features
●Capable of performing high-resolution inspection with 7500-pixels CCD image sensor.
●The pixel size is large enough (9.325μm×9.325μm) to capture high S/N images.
●The high speed operation at 50MHz data rate.
●10 or 8 bit digital image signal output complying with Camera Link standard (Medium/Base Configuration).
●GAIN and OFFSET characteristic can be easily adjusted with RS232C communication (Camera Link spec.).
●8/10 bits format can be easily changed by the communication command(RS232C).
●The equipment operates with a single DC12V power source.
●Possible to get stable video signal despite a change of ambient temperature, as the dark current correction
circuit is incorporated.
●Internal Gain position (1,2,3….7,8 ×) is easily selected by the switch.
●Reduction in size and weight has been realized by adopting original circuit and mechanism design.
●The exposure control function is incorporated. (at below 3.1kHz in scan rate)
3. CCD image sensor
The CCD image sensor Is characterized by 9.325μmsquare pixel, 7500 effective pixels and high speed
performance. Charges accumulated in single-row photo diodes are output thorough two shift registers,
respectively. (One for ODD numbered charges, and the another for EVEN numbered charges) It realizes high
transfer efficiency and image uniformity by employing two shift registers.(It is not illustrated in the diagram
below.) Each shift register operates at the rate of 25MHz.

It is able to monitor the video signal of each RGB line from the Video
monitor terminal by pressing the “Video monitor signal selector switch”.
Every time the selector switch is pressed, LED indicator of RGB lights
up by rotation.
6. How to change settings
The GAIN value of video signal is able to change by RS232C communication. Also It is able to change in the
following manner when not to use RS232C communication.
6-1 Fine adjustment of ODD/EVEN video signal on each RGB line
It is able to fine adjust the ODD/EVEN video signal on each RGB line
by the fine control volume in the right figure.
6-2 How to change camera GAIN
The camera gain has been set to “×1”as a factory default.
It is able to octuple the gain using the built-in GAIN switch.
Select “×1”when high-quality image is needed, and select “×8”when high sensitivity is needed even if image
quality degrades.

[ Description of exceptional case]
＊NG is returned in case of command input error or inputting nonexistent command.

Input: chake
Output: NG
＊NE is returned in case of numeric entry error.
e.g. : Input error (Input value is beyond the setting range.)
Input: gainpos=96
Output: NE
e.g. : Input error (Input value is beyond the setting range.)
Input: ch1gain1=2000
Output: NE
＊NC is returned in case of inputting invalid value under the condition that the ctrl setting (DIP-SW setting) is 0.
e.g. :
Input: ch1gain=96 (at ctrl=0)
Output: NC
＊TO is returned when a command input period overruns the time-out period (15 sec.).
e.g. :
Input: gainpo (No CR entry)
Output: TO
＊” ? ”at the bottom of Command is omissible
e.g. :
Input: id
Output: 0
