Function
Activates data communication with IC1121 (CAMERA DSP).
Not used. Open.
Activates focus drive data communications with IC1302 (FOCUS
MOTOR DRIVE).
Activates zoom drive data communications with IC1301 (ZOOM
MOTOR DRIVE).
Outputs focus motor drive signal to IC1302 (FOCUS MOTOR DRIVE).
Outputs zoom motor drive signal to IC1301 (ZOOM MOTOR DRIVE).
Outputs IR motor drive signal to IC1380 (IR MOTOR DRIVE)
3V power input.
External sync detection input. When "Hi" is input, the unit will be
driven in the external sync mode; when "Lo" is input, it will be driven
in the internal sync mode.
Ground.
Issues a command which determines with IC1380 (IR MOTOR
DRIVE)
