Pin No.| Signal Signal level
10 RGB/NORMAL mode select High state (5 V or open): RGB inputs from a microcomputer
Low state (ground): Composite video inputs from the LINE A VIDEO IN connector
14 V-sync Negative polarity
TTL level
12 Blanking High state (5 V or open): Video inputs from a microcomputer only
Low state (ground): Composite video input from the LINE A VIDEO IN connector
During the tow state, the video signal from the microcomputer is blanked and the
composite video signal from the LINE A VIDEO IN connector is superimposed over
i the signal from the microcomputer.
13 Audio input Input level —5 dB (100% modulation), input impedance more than 47 k ohms
