1. Introduction Thank you very much for your purchase of the Hitachi BE-IR30/31 Black and White Camera Module. Prior to using this camera , read this manual carefully. 2. General The BE-IR30/31 is a monochrome camera module featuring sensitivity in the near infrared spectrum using a 1/3-inch size CCD imaging device. Resolution is outstanding, while the very small size provides optimum suitability for incorporation into equipment where space is limited.

5. Notes to users Power supply z Connect a 9V DC voltage (8.5 to 9.5V) from an external regulated DC power supply. z Use a stable power supply without ripple and noise. z Prior to turning on the power switch , check that the polarities of the power cable are correct , referring to the connection diagram (Page 11 , 12) To protect CCD (sensor) z Do not touch the glass surface of the CCD sensor to avoid deterioration in picture quality due to dirt and scratches.
5. Notes to users Phenomena inherent to CCD imaging device Following are phenomena inherent to a CCD imaging device , and not defects. z Smear and blooming When strong light (lamp , fluorescent lamp , reflected light , etc.) is shot , pale bands are displayed vertically above and below the light. In this case , change the angle of the camera so that such strong light does not enter the camera through the lens.

8. Installation When installing the camera in a housing or unit of equipment, secure with two M2 screws inserted into the 2.5 mm diameters holes of the SENS board base plate. Two 2.5 mm Dia. SENS board 1. Use the SENS board holds to install the camera. Avoid using only the Main board, Notes : due to risk of damage to the board connector. 2. Avoid unnecessary stress on the printed board when engaging and disengaging the connectors. 3.

11. Function setting and changes When changing the function settings , perform the work with thorough care. Be sure to use anti-static measures such as a grounding band. Also observe safety precautions when soldering to avoid burn and fire hazards. Hitachi Denshi assumes on liability for damage or injury resulting from such work. Since the function setting can be provided at the time of shipment , consult a Hitachi Denshi representative. 11-1 AGC on / off Factory setting is AGC off (fixed gain).
11. 11-2 Function setting and changes Gamma response The factory setting is gamma on. If necessary , the gamma response can be changed as follows. Change the gamma response by changing the chip part.
