High state (5 V): IBM mode
Low state: 3 Bit TIL
0
High state (5 V or open): Audio inputs from pin 13.
Low state (less than 0.4 V): Audio inputs from the LINE A/LINE B AUDIO IN jacks or VTR
connector
Negative polarity
When the high state is selected at pin 9:
1 Vp-p, 75-ohm terminated
When the low state is selected at pin 9:
TIL level
Positive polarity
When the high state is selected at pin 9:
Analog signal (0.7 Vp-p, 75-ohm terminated, non sync
1 Vp-p, 75-ohm terminated, with sync on G-signal)
When the low state is selected at pin 9:
Digital signal (TIL level)
-
High state (open): Analog signal (0.7 Vp-p)
Low state (ground): Digital signal (TIL level)
High state (5 V or open): RGB inputs from a microcomputer
Low state (ground): Composite video inputs from the LINE A/LINE B VIDEO IN or VTR
connector

Negative polarity
TIL level
High state (5 V or open): Video inputs from a microcomputer only
Low state (ground): Composite video input from the LINE A/LINE B VIDEO IN or VTR
connector
During the low state, the video signal from the microcomputer is blanked and the
composite video signal from the LINE A/LINE B VIDEO IN or VTR connector is
superimposed over the signal from the microcomputer.
Input level -5 dB (100% modulation), input impedance more than 47 k ohms
