POWER AND VIDEO CONNECTIONS MC3700 Series camera is designed to operate from a 12 VDC or 24 VAC power supply. The power supply connections are shown in Figure 4. The LED on the back panel of the camera indicates that power is connected. Use only a Class 2 isolated power supply. Power consumption is less than 5 watts. CLASS 2 ISOLATED POWER SUPPLY CLASS 2 ISOLATED POWER SUPPLY 24 VAC 12 VDC Figure 4. Power Supply Connections To connect the camera power and video: 1.
AC Operation Only – If you are wiring more than one camera to the same transformer, connect one side of the transformer to the same terminal on all cameras, and connect the other side of the transformer to the remaining terminal on all cameras. Failure to connect all of the cameras the same way will cause the cameras to be out of phase with each other and may produce a vertical roll when switching between cameras. Table A.
LENS SETUP AND FOCUS PROCEDURES Video Drive Auto Iris Lens When a video drive auto iris lens is used, the lens mode selector switch must be set to AIV. Switch the ESC and AGC OFF. Refer to the lens instructions and adjust the lens for the optimum picture (video output level of 1V peak-to-peak). Switch the AGC ON. To focus, fully open the iris by covering the lens with a suitable neutral density (ND*) filter. If the viewed scene is 6.5 feet (2 m) away or farther, set the lens focus to infinity (far).
BACK FOCUS ADJUSTMENT The back focus adjustment is located at the front of the camera and is accessible from either side of the case. To adjust the back focus: 1. Loosen the two back focus locking screws (one on each side). 2. Turn the back focus ring: a. Clockwise - Moves the CCD sensor assembly towards the back of the lens. b. Counterclockwise - Moves the CCD sensor away from the lens. 3. When the back focus adjustment is satisfactory, tighten the locking screws.

AGC OFF/AGC ON – Switch Setting 5 Automatically adjusts the image to compensate for low light levels when using fixed or manual iris lenses. AGC (Default setting) - Enables the AGC mode. OFF - Disables the AGC mode. ESC ON/ESC OFF (Electronic Sensitivity Control) – Switch Setting 4 The ESC feature compensates for an excessive light level by automatically adjusting shutter speed. Selecting ESC Iris disables manual shutter speed selection.
CAMERA SYNCHRONIZATION When using one AC power supply in a multi camera system, a brief vertical roll may occur on the monitor each time a camera view is switched. To eliminate vertical roll adjust the phase control to synchronize (line-lock), the cameras to one another. The synchronization switch (DIP switch 10) for each camera must be set to LL.
