Input Inverter
The signal level of input lines is configurable for the MARS-GT series camera. The user can select whether
the input level is reverse or not by setting "LineInverter".
For the MARS-GT 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:

Output Mode Operation

Configuring Line as output
The MARS-GT series camera has two output signals: Line1, Line2. In which the Line1 is a uni-directional
opto-isolated output I/O, Line2 is bi-direction configurable I/Os.
The camera's default output is Line1 when the camera is powered on. Line2 can be configured to be output
by changing the "LineMode" of this line.
Each output source of the two output lines can be configurable, and the output source includes: Strobe,
UserOutput0, UserOutput1, UserOutput2, ExposureActive, FrameTriggerWait, AcquisitionTriggerWait.
The default output source of the camera is UserOutput0 when the camera is powered on.
What status (high or low level) of the output signal is valid depends on the specific external circuit. The
following signal diagrams are described as examples of active low.
