Alignment and Adjustments WARNING: The main board should be replaced if the back focus is twisted. Note : Ther is no need to adjust the focus for changing the CCD only 5-1 Camera Adjustment Note : DNP 3100°K light box, 5100°K color temperature conversion filter and adjustment program. A PC is needed for camera adjustment - Flash memory format : Configure the system, and store the “bad block” information - V-Sub voltage adjustment : Adjust the V-Sub voltage of CCD. (Refer to table on page 5-4) * AE_BTM adjustment : Adjust the offset of image from A/D converter, and set the reference to black * 3100°K AWB reference measurement : Take a shot of the white chart (3100°K), and extract the reference at 3100°K. * AGC gain adjustment : Extract the AGC gain of 0dB, 6dB * 5100°K adjustment: Take a shot of the white chart (5100°K), and extract the reference at 5100°K. 15Cm RS-232C < 3100 K DNP Light BOX > PC 5100 K < KenKo C14 49mm > Fig. 5-1 5-2 Installing and using special softwre (on diskette) Note: Special software handles the camera adjustment and fault diagnostics.
