This status shows a failure of System-boot operation of this product. If an
appropriate voltage is not provided to CIS, this status happens. Please
check the following points.
①Is the same voltage supplied as the pin assignment table supplied to each
terminal of the V1V3 connector that supplies DC5V? (If +5V and GND pins
specified on the pin assignment table are not connected, the sensor
board cannot operate correctly.)
②Is the current limiter setting of your DC5V power unit too low when
power on?
③Is the voltage of DC5V less than 4.75V?
If not above, CIS might be broken or damaged.
