Operation as an Output

This section describes the electrical operation of the GPIO line when the line has been set to
operate as an output.
5.9.3.1

Electrical Characteristics

NOTICE
Voltage outside of the specified range can cause damage.
You must supply power within the specified voltage range.
To ensure that the specified voltage levels for signals transmitted out of the
camera will be reached even under less than favorable conditions (eg. for long
cable lengths, harsh EMI environment, etc.), we recommend to generally use an
external pull up resistor or to connect a "high side load".
The following I/O supply voltage requirements apply to a direct-coupled GPIO line when it is

set as an output and when it is in the "off" state:
Voltage
+30.0 VDC
+3.3 to +24 VDC
< +3.3 VDC
Table 11: Voltage Requirements for a Direct-coupled GPIO Line Set as an Output
The following applies to a direct-coupled GPIO line when it s set as an output and when it is in

the "on" state:
The camera uses an open collector with only a weak internal pull-up resistor (approximately
2 kΩ). It is therefore likely that many applications will have to provide an additional pull-up re-
sistor.
The residual voltage will typically be approximately 0.4 V at 50 mA and 25 °C housing temper-
ature. The actual residual voltage, however, depends on camera operating temperature, load
current, and production spread.
Note: The maximum current allowed through the output circuit is 50 mA.

Significance
Absolute maximum; the camera can be damaged if the absolute maximum is
exceeded.
Recommended direct-coupled GPIO output supply voltage range.
The direct-coupled GPIO output can operate erratically.
