1. Introduction Thank you very much for your purchase of the Hitachi BE-IR20/21 Black and White Camera Module. Prior to using this camera , read this manual carefully. 2. General The Hitachi BE-IR20/21 are black and white camera modules using a 1/4 inch interline CCD. The BE-IR20/21 are so small that they are most suitable for use with the equipment provided with limited space. BE-IR20 : Internal sync BE-IR21 : External sync 3.
． ．Specifications 8) External sync input HD & VD : 5V peak-to-peak negative Input impedance : 1kΩ Frequency deviation : ±1% 9) Video output 1.0 Vp-p, 75Ω, unbalanced Video component : 0.7 Vp-p Sync component : 0.3 Vp-p negative 10) Resolution EIA : 570(H)×380(V) TV lines CCIR : 560(H)×380(V) TV lines 11) Signal to noise ratio 56 dB 12) Auto electronic shutter Provided (factory setting OFF) 13) Automatic gain control (AGC) Max. 32 dB approx.
. 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 8 , 9) 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.
6. External view Dimensions 7. Optical dimensions Lens Lens-mount 19.2 ± 0.5 (C-mount) Extension of optical path due to the thickness of CCD glass is considered. CCD 1.4 ± 0.
. 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.
11. 11-3 Function setting and changes Auto electronic shutter on / off Factory setting for auto electronic shutter is off. If necessary , it can be set to on. Absent the R259 , R260 chip to set the auto electronic shutter to on.
11. 11-4 Function setting and changes Changes to fixed shutter mode The fixed shutter mode can be changed by replacing the chip parts indicated below.
11. 11-5 Function setting and changes BE-IR20 external sync The BE-IR20 factory setting is for internal sync. If required, this can be changed to external sync by changing chip parts. Change the following chip parts for external sync operation.
11. 11-6 Function setting and changes BE-IR21 internal sync The BE-IR21 factory setting is for external sync. If required, this can be changed to internal sync by changing chip parts. Change the following chip parts for internal sync operation.
11. 11-7 Function setting and changes HD and VD output (BE-IR20 only) The BE-IR20 can be provided with horizontal and vertical drive outputs by changing chip parts. Change the following chip parts to provide HD and VD outputs.
