4) Input Inverter
The signal level of input lines is configurable for the MARS-U3 series camera. The user can select whether
the input level is reverse or not by setting "LineInverter".
For the MARS-U3 series camera, the default input line level is false when the camera is powered on,
indicating that the input line level is not reversed. If it is set as true, indicating that the input line level is
reversed. As shown in the Figure 8-3:

8.1.2. Output Mode Operation
1) Configuring Line as output
The MARS-U3 series camera has three output signals: Line1, Line2, and Line3. In which the Line1 is a
uni-directional opto-isolated output I/O, Line2 and Line3 are bi-direction configurable I/Os.
The camera's default output is Line1 when the camera is powered on. Line2 and Line3 can be configured
to be output by changing the "LineMode" of this line.
