Cameras of the Baumer HXG series are equipped with three input lines and three output
lines.

11.6.1.1 Circuits
Notice
Low Active: At this wiring, only one consumer can be connected. When all Output pins
(1, 2, 3) connected to IO_GND, then current flows through the resistor as soon as one
Output is switched. If only one output connected to IO_GND, then this one is only us
-
able.
The other two Outputs are not usable and may not be connected (e.g. IO Power V
CC
)!

11.6.1.2
Inputs
The wiring of these input connectors is left to the user.
Sole exception is the compliance with predetermined high and low levels (0 .. 4,5V low,
11 .. 30V high).
The defined signals will have no direct effect, but can be analyzed and processed on the
software side and used for controlling the camera.
The employment of a so called "IO matrix" offers the possibility of selecting the signal and
the state to be processed.
On the software side the input signals are named "Line0", "Line1" and "Line2".
