The video output signal will be connected to the camera controller unit.
The camera control command signal from camera controller unit is multiplexed
on the video signal at CN3, pin3 on the Communication Board.
This multiplexed video signal (Video FB) will be fed back to IC201, pin27 (Auto
Focus Board) via CN7, pin6 (Communication Board)
Æ Slip Ring Æ CN3, pin3
(Servo Board)
Æ CN1, pin23 (Servo Board) Æ CN4, pin2 (Digital Board).
In IC201, the camera control command (Data 2) will be separated from video
signal and is appeared at pin24 of IC201 then supplied to pinY6 of IC2.
The data 2 will be supplied to IC1 (CPU). The Data 2 contains the lens control
signal, pan/tilt control signal and camera menu control signal.
Drive Board
In IC1501, there are 5 major functions such as CCD noise reduction (S/H), AGC,
Gamma correction, Amplifier and A/D convertor.
The CCD H-drive signals are generated by IC1501. The CCD V-drive signals are
generated by IC2 then supplied to CCD through IC301 (Driver).
IC300 is a DAC (Digital to Analog Converter) which converts the serial data
(SDOUT) from IC1 (CPU) to analog command
data.(CH6,CH8,CH9,CH10,CH11).
Auto Focus Board
The CPU (IC1) on the Digital Board sends out the lens control signal
(AFDRTXD) from pin28.
This signal is supplied to IC203 (Lens Motor Driver) pin34 on the Auto Focus
Board.
The auto focus control signals (C1/C2/D1/D2) and zoom control signals
(A1/A2/B1/B2) are generated by IC203 and are supplied to the lens.
IC204 is an ALC control IC. The analog data (CH10) from IC300 is supplied to
IC204, pin2. IC204 generates the iris drive signal to the lens.
The lens sends back a damper signal to the IC204.
