Status LED indicates Orange after turn on CIS
This status shows that DC5V power supply voltage down to 3.4V on CIS
internal board.
Change power supply voltage to maximum voltage within Standard
Operating Conditions and Check the voltage is 5V near the power supply
connector on CIS.
If voltage is 5V, CIS might be broken or damaged.

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.)
②
Is the current limiter setting of your DC5V power unit too low when
power on?
③
Is the voltage of DC5V less than 4.75V?
If not above, CIS might be broken or damaged.
