The 12V DC or 24V AC power supply cord can be connected to this terminal. The camera detects the power source automatically. 1. 12 V DC Power Supply Connect the power cord to the AC/DC compatible input terminal on the rear panel of the camera.

It is recommended to use a monitor whose resolution is at least equal to that of the camera. 2. Set the termination switch to the 75ft position on the last monitor. A. Use a 75ft coaxial cable. B. Set the termination switch to the 75ft position on the last monitor and to the Hi-Z position on the other monitors. Do not change the positions after setting.

Wiring precautions • Do not bend the coaxial cable into a curve whose radius is smaller than 10 times the cable’s diameter. • Never staple the cable even if with circular staples. Impedance mismatching will occur. • Never crush or pinch the cable. All of the above will change the impedance of the cable and cause poor picture quality. -9- Installation of Auto Iris Lens Connector Install the lens connector (YFE4191J100) when using a video drive ALC lens. The installation should be made by qualified service personnel or system installers. (1) Cut the iris control cable at the edge of the lens connector to remove the existing lens connector and then remove the outer cable cover as shown in the diagram below. The pin assignment of the lens connector is as follows: Pin 1 : Power source; +9V DC, 50mA Max. Pin 2: Not used Pin 3: Video signal; 1.3 V[p-p]/40 k£2 Pin 4: Shield, ground Rib Pin 1 Pin 4 (2) After connection, assemble the lens connector as follows. Note: When the iris control cable is too thick to lock the connector cover with the connector base, cut off the rib on the connector. (Select VIDEO for LENS DRIVE of the CAM SET UP menu.) Mounting the Lens Caution: Before you mount the lens, loosen the two screws on the ring, and rotate this ring clockwise until it stops. If the ring is not at the end, the inner glass or CCD image sensor may be damaged. 1. Mount the lens by turning it clockwise on the lens mount of the camera. 2. Connect the lens cable to the auto iris lens connector on the side of the camera. Caution for Mounting the Lens The lens mount should be a C-mount or CS-mount (1”-32UN) and the lens weight should be less than 450g (0.99 lbs). If the lens is heavier, both the lens and camera should be secured by using the supporter. The protrusion at the rear of the lens should be as shown below: C-mount: Less than 11 mm (7/16") CS-mount: Less than 6 mm (1/4") FOCUS OR FLANGE-BACK ADJUSTMENT The following adjustment should be made by qualified service personnel or system installers. 1. Loosen the screws on the flange-back-adjusting 2. Turn the flange-back adjusting ring to the desired position. Caution: When the C-mount lens is mounted, do not rotate the ring counterclockwise by force after it stops. If the ring is rotated by force, the inner lens or CCD image sensor may be damaged. „ ring.

INSTALLATION OF CAMERA • Mounting from the bottom This camera is designed to be mounted from the bottom, as shown below. The mounting hole is a standard photographic pan-head screw size (1/4" -20).
