1-4. Function of Internal Switch

� S1102 (SEQ +/-) Select �+� or �-� according to a waveform monitor in use. + : NPN open collector output - : PNP open collector output Factory-setting is �-�. � S1361 (I ON/OFF)... for CCU-700A � S1361 (U ON/OFF)... for CCU-700AP This switch is used for the encoder circuit adjustment. When the switch is set to �OFF�, the I/U signal is not added to the chroma circuit. Therefore, the composite video signal (VB or VBS) output from the CCU does not contain the I/U signal. Normally set to �ON� (marked position). � S1362 (Q ON/OFF)... for CCU-700A � S1362 (V ON/OFF)... for CCU-700AP This switch is used for the encoder circuit adjustment. When the switch is set to �OFF�, the Q/V signal is not added to the chroma circuit. Therefore, the composite video signal (VB or VBS) output from the CCU does not contain the Q/V signal. Normally set to �ON� (marked position).

Mark S1361, S1362 Factory setting

� S1962 (REMOTE/LOCAL) This switch selects whether the master setup unit MSU performs the following adjustments or the CCU-700A does. � H and SC phases synchronization with an external genlock signal � NOTCH level and width adjustments (CCU-700AP only) REMOTE : The master control unit does. LOCAL : CCU-700A does using the switch and controls on the VA-156A/156P board. S1961(SC STEP)�for SC PHASE adjustment RV1961(SC FINE) RV1962(H PHASE)�for H PHASE adjustment RV1963(H FINE) RV1501(NOTCH LEVEL)�for NOTCH adjustment RV1502(NOTCH WIDTH) (CCU-700AP only) When using a remote control unit of RCP-700 series not having the above control functions together with the CCU, be sure to set S1962 to �LOCAL�. Factory-setting is �REMOTE�. � S2031 (SKIN SIGNAL ON/OFF) When this switch is set to �ON�, the I axis signal (skin signal) is mixed with the color-bar signal output from the CCU. This skin signal can be monitored by turning on the CB 3 button in the MSU touch panel. When the switch S2031 is set to �OFF�, the skin signal can not be monitored even if turning on the CB 3 button of the MSU. Factory-setting is �ON�.
B/W SKIN signal COLOR

� S1501 (NOTCH ON/OFF)�CCU-700AP only A cross color of the VBS output will be reduced by turning on the notch filter circuit. To adjust the notch filter circuit, use controls on the VA board or the MSU700 touch panel. And to turn on or off the circuit use the switch S1501 or the MSU-700 touch panel. �ON� operation has a priority. Normally set this switch to �OFF�. � S1891 (H BLKG) Used to adjust the H blanking width. The pulse width is factory-set to 10.9 ± 0.2 µs for CCU-700A and to 12.0 ± 0.2 µs for CCU-700AP. Set according to use. � S1892 (V BLKG)... CCU-700A only Used to set the V blanking width to 19H, 20H or 21H. Factory-setting is �20H�. Set according to use. � S1961 (SC STEP) Used to adjust the subcarrier phase. One step of this switch changes 90 degrees. This switch activates only when the switch S1962 is �LOCAL�.

at color-bar signal output (CB GATE ON)

� S2032 (CB SELECT) This switch selects a color-bar signal the CCU outputs. The following signals can be output. CCU-700A : SMPTE, EIAJ, FULL CCU-700AP : EBU, 95 % CB Factory-setting is �SMPTE� for CCU-700A and is �EBU� for CCU-700AP.
