Output levels
Status LED
Alvium CSI-2 cameras have a green status LED. The following table describes the
flashing pattern indicating different events. Inverse flashing: If the LED is already
on, it is switched off for a short time.

NOTICE
Damage to the camera by high output current or voltage
The camera can be damaged when connected to a device that exceeds the specified
maximum current or voltage. Consider maximum values:
• Max. current = 12 mA per output
• Max. Out VCC = 3.3 VDC

(high) = On state
The voltage level in the On state depends on the load current. Higher currents yield
lower voltage.
