Camera Mounting Use a standard 1/4-20 screw (provided) with a maximum thread length of 3/8-inch (10 mm) for top or bottom camera mounting. The mount adapter may be fitted to the top or bottom of the camera. The camera is shipped with the mount adapter located on the top of the camera. 1 To change the mount adapter position: 2 Remove the four screws from the mount adapter located on the top of the camera. Remove the trim cover from the bottom of the camera by prying it loose.
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 Set the lens mode selector switch to AIV. Switch the ESC OFF. Refer to the lens instructions and adjust the lens for the optimum picture (video output level of 1V peak-to-peak). 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 until the object is in focus. 3. When the back focus adjustment is satisfactory, tighten the locking screws. Do not over tighten the locking screw or force the back focus adjustment ring.

To eliminate vertical roll, adjust the phase control by synchronizing, or line-locking, the cameras to one another. Use the phase potentiometer located on the side of the camera (refer to Figure 1) to make adjustments.
