. S1102 (Q/U ON/OFF) This switch is used for encoder circuit adjustment. When this switch is set to OFF, no Q/U signal is contained in the composite video (VB or VBS) signal that this unit outputs because a Q/U signal is not input to the chroma circuit (double-balanced circuit). Factory setting: ON . S1501 (H BLKG) This switch is used for H blanking width adjustment. During factory setting, this switch is set so that the H blanking width is 10.9 ± 0.2 usec for CCU-550 and 12.0 ± 0.2 usec for CCU-550P. Set this switch according to the application. . S1502 (V BLKG 19H/20H/21H) This switch sets the V blanking width to 19H, 20H, or 21H. Set this switch according to the application. Factory setting: 20H

. S1601 (REMOTE/LOCAL (0d)/LOCAL (180d)) This switch selects whether to control the alignment of H.SC phase with an external genlock signal by a master setup unit (MUS-700) or this unit. The alignment of the H.SC phase can be controlled using RV1601 and RV1604 on the VA board when this switch is set to LOCAL. Set this switch to LOCAL when the remote control panel RCP series without H.SC phase control are connected to this unit. The SC phase can be selected to 180dwhen this switch is set to LOCAL (0d) and LOCAL (180d). Factory setting: REMOTE

. S1701 (CB SELECT) This switch sets the color bars signal output by this unit to SMPTE, EIAJ, or FULL. Set this switch according to the application. Factory setting: SMPTE for CCU-550 EBU for CCU-550P . S1503 (VCO ON/OFF) To stop the VCO oscillation, set this switch to OFF. Factory setting: ON . S401 (Y.R-Y.B-Y/RGB) This selects the signals of the Y/G, R-Y/R, and B-Y/B OUT connectors on the rear panel. Factory setting: Y/R-Y/B-Y . S1201 (VBS3/SYNC) This switch selects the signal of the VBS3 OUT connector on the rear panel. 1-9
. S901 (SEQ ON +/_) Select this switch to + or - according to the waveform monitor to be used. +: NPN open collector output _: PNP open collector output Factory setting: _ . S1101 (I/V ON/OFF) This switch is used for encoder circuit adjustment. When this switch is set to OFF, no I/V signal is contained in the composite video (VB or VBS) signal that this unit outputs because an I/V signal is not input to the chroma circuit (double-balanced circuit). Factory setting: ON
