The motor driving direction is determined by FMDIR signal.
14.2.3.4. EEPROM Block
- EEPROM (IC1009)
Power-supply voltages: 3.3V
Package: 8pin SOP
Memory Capacity: 2K x 8bit
It shall be READ/WRITE by I2CBUS signal (SCL, SDA). Memorizes
the values of LENS adjust, VIDEO adjust and VIDEO DSP install.
When the power is ON or camera unit is reset, it is READ and
installed to each system.
14.2.3.5. LED Block
A line crack and a control signal relay a Tilt board and a Video board from IP CPU by which
control of LED was mounted on the Main board, and it is inputted into the LED control circuit
mounted in the Lens board.
(As for LED, the 3 color LED is used.)
