Power supply and digital input
The maximum input current of the camera is 200 mA over the entire input voltage range with lens heating
deactivated. When lens heating is activated, this maximum input current is 700 mA.
By triggering the digital input DIGIN, recording a video file is initiated.
The maximum digital input current is 7 mA over the complete specified digital input voltage range.
3.3
Ethernet interface
A network interface is used for IPv4 communication with the camera.

Table 3.1:
Pinout power supply and digital input
NOTICE
This requires a rising edge at the DIGIN input into the logical "High" range starting from the
specified logical "Low" range and a corresponding minimum pulse length of 20 ms. A logic
"low" signal must also be present for 20 ms for retriggering. Furthermore, after a trigger is
accepted, renewed acceptance is blocked by software for 2 s.
NOTICE
Trigger signals with a pulse length of < 1.5 ms are not accepted. Pulses with length between
1.5 ms and 20 ms can eventually cause a trigger.
CAUTION
The power supply must be provided by a normal DC power supply unit. Connection to a direct
current supply network is permissible.
