O Lo Activates focus drive data communications with IC1302 (FOCUS
MOTOR DRIVE).
O Lo Activates zoom drive data communications with IC1301 (ZOOM
MOTOR DRIVE).
O (Pulse) Outputs focus motor drive signal to IC1302 (FOCUS MOTOR DRIVE).
O (Pulse) Outputs zoom motor drive signal to IC1301 (ZOOM MOTOR DRIVE).
O (Pulse) Outputs IR motor drive signal to IC1380 (IR MOTOR DRIVE)
----- 3V power input.
I Hi/Lo 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.
O Hi/Lo Issues a command which determines with IC1380 (IR MOTOR
