Input Lines
The camera is equipped with two physical input lines designated as Input Line 1 and Input Line 2.
The input lines are accessed via the 12-pin receptacle on the back of the camera.
As shown in the I/O line schematic, each input line is opto-isolated. For each line, the minimum input
voltage to indicate a logical one is +5 VDC and the maximum is +24 VDC. An input voltage less
than +5 VDC means a logical zero. The current draw for each input line is between 5 and 15 mA.
Figure 27 shows an example of a typical circuit you can use to input a signal into the camera.
By default, Input Line 1 is assigned to receive an external hardware trigger (ExTrig) signal that can
be used to control the start of image acquisition.
