Resumen del manual
YFE4191J100). This male connector can be installed on lenses which have incompatible type connector. See page 16 for installation details (2) Flange-back Adjusting Ring This ring is used to adjust the back focal length or picture focus by rotating this ring to clockwise for C-mount lens or counterclockwise for special C-mount (CS-mount) lens. (3) Lens (Option) See pages 10, 11, 12, 13 and 14 for details on lens selection. (4) Camera Mounting Screw Hole This threaded hole (1/4”-20) is used to mount the camera onto a mounting bracket or tripod. (5) DC 12V In Terminal (DC 12V IN) This terminal accepts 12V DC power source (10.5V- 16V) Cautions: 1. Connect this to a 12V DC class 2 power supply only. 2. To prevent fire or shock hazard, the UL listed wire VW-1, style 1007 should be used for the cable for DC 12V Input Terminal. (6) AGC On/Off Switch (AGC ON/OFF) This switch is used to select the gain of the video amplifier as follows; ON: When the lens iris is fully opened under a low light condition, a clear picture is obtained by automatic increase of the gain. OFF: A natural and low-noise picture is obtained under a low light condition. (7) Electronic Light Control / Automatic Light Control Selection Switch (ELC/ALC) This switch is used to select the lens as follows. ALC: Choose this position when using an auto iris lens. ELC: Choose this position when using a fixed or manual iris lens. Lens Selection Switch (VIDEO/DC) This switch is used to select the supplied auto iris control signal to the lens from the Auto Iris Lens Connector (1). DC: Choose this position when the auto iris control lens requiring DC control signal is mounted on the camera. See pages 10, 11, 12 and 13 for a list of these lenses. VIDEO: Choose this position when the auto iris control lens requiring video signal such as WV-LA8B, WV-LA16B, WV-LA25B, WV-LA50B, is mounted on the camera. Gen-lock Termination Switch (G/L 75ft / Hi-Z) When looping through the Gen-lock video input signal, set this switch to the Ht-Z position and in all other cases, set this switch to the 75-ohm position. Auto Iris Level Control (ALC LEVEL, L (Low)/ H (High)) This control adjusts the control level of the auto iris control when the Lens Selection Switch (8) is set to the DC position and the auto iris lens which requires the DC control voltage such as WV-LA12 etc., is mounted on the camera. Note: When the Lens Selection Switch (8) is set to the VIDEO position, the auto iris level control should be adjusted by the lens. (11) Video Output Connector (VIDEO OUT) This connector is used to connect a coaxial cable to the VIDEO INPUT of the specified monitor. This connector may be connected to the CAMERA INPUT of the camera drive unit. The camera drive unit supplies DC power and vertical drive pulses, and video output from the camera. (12) Gen-lock Video Input Connector (GEN-LOCK) A composite B/W or color 1.0 Vp-p/75 ohms video signal, or black burst 0.3 Vp-p/75 ohms or composite sync 4 Vp-p/75 ohms should be supplied to this connector for external synchronization. CONNECTION 1. A 12V DC power supply is required. 2. Connect the power cable to the DC 12V In Terminal (5) on the rear panel of the camera.

Video Cable 1. It is recommended to use a video monitor whose resolution is at least equal to the camera's. 2. Terminate the camera output with 75-ohm resistor at the furthest end of its cable run. • It is recommended to use 75-ohm coaxial cable. • Always set the last monitor's termination switch to 75 ohms, and set the termination switches of intermediate monitors to HIGH (Hi-Z) position. Monitor Monitor • The maximum extensible coaxial cable length between the camera and the monitor is shown in the table 1. Since cable quality varies among manufactures, please verify video quality before final installation, if maximum lengths are to be used.

Wiring precautions: • Do not bend coaxial cable into a curve whose radius is smaller than 10 times the cables diameter. • Never staple the cable-not even with circular staples. ...
