Basler IP Fixed Box Cameras
Pin #:
4, 6, 8
Function:
I/O-0, I/O-1, and I/O-2 respectively
Description:
Each I/O port can be set to operate either as an input or as an output.
The choice of whether a particular I/O port will operate as an input or an output and
how it will function is made by setting camera parameters (see the camera user’s
manual for details about setting camera parameters).
For any I/O port set as an input:
Variant 1 (input port connected to ground (pin 1) via a switch):
In the schematic drawing (variant 1) on page 24, I/O-2 has been set to operate as an
input. Normally, you will connect an input port to ground via a switch as illustrated in
the schematic.
As indicated in the table below, an input port will be detected by the camera as active
or inactive depending on whether the switch is open or closed and whether the port
is or is not set to invert.
See the camera user’s manual for more information about setting a port to invert.
