Basler IP Fixed Dome Cameras
Hole Name:
I/O-0, I/O-1
Function:
I/O port 0 and I/O port 1 respectively. 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 an I/O port set as an input:
In the schematic drawing on
page 88
, I/O-0 has been set to operate as an input. Normally, you will connect an
input port to I/O 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.

For an I/O port set as an output:
In the schematic drawing on
page 88
, I/O-1 has been set to operate as output. An output port employs an
open collector transistor connected to ground as shown in the schematic.
As indicated in the table below, an output port will or will not be connected to ground via the transistor
depending on the state of the port 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.
Note:
If an output port has been set to invert and you restart the camera or you power it off and back on, the
port will not invert during the camera bootup process and will return to inverted once the bootup process is
complete.

The maximum load is 100 mA and the maximum voltage is +24 VDC.
If an inductive load such as a relay is connected to an output port, a diode must be connected in parallel with
the load.
