Input levels
The GPIOs can be connected directly to the system controlling the camera for
voltages up to 5.5 VDC. An external resistor is not necessary.
Output levels
NOTICE
Damage to the camera by high input voltage
Exceeding the maximum input voltage can damage the camera.
Keep maximum input voltage below 5.5 VDC.
Parameter Value

NOTICE
Damage to the camera by high output current
The camera can be damaged when connected to a device that exceeds the specified
maximum current or voltage. Keep the maximum current below 12 mA per output.
Parameter Value
External output voltage U

(low, Off state) 0 to 0.4 VDC
External output voltage U

(high, On state) 2.4 to 3.3 VDC
Undefined levels 0.4 to 2.4 VDC
Maximum external output voltage 3.3 VDC
Maximum output current 12 mA

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