Configuring the Camera
External Trigger = The external trigger function is used to control the exposure start without

having to use any other parameters. If the Function parameter of an input port is set to
"External Trigger" and no external trigger is applied, the camera immediately stops grabbing
images.
If this function is used and the Encoder Mode parameter is set to "CBR" or "CVBR" (see
page 31), the camera's sensor frame rate has to be set manually via the Frame Rate Mode
parameter in the Sensor group (see
the encoder needs a constant bit rate as input. As this is difficult to achieve with external
triggers, which can be applied at irregular intervals, and because the camera does not measure
the current frame rate, you have to set a frame rate manually. For the encoder to be able to
calculate the desired bitrate for CBR and CVBR correctly, the frame rate mode should be set to
the same frame rate as the frequency of the externally applied triggers.
If the Direction parameter is set to output, the list of available functions will be:
User Output = You can set the state of the output port by checking or clearing the State check

box on this tab. When the check box is checked, the port will be active, when the check box is
unchecked, the port will be inactive.
IR Filter Announce = The output port will "announce" the position of the camera's IR-cut filter.

When the filter is in the night position, the port will be active. When the filter is in the day
position, the port will be inactive. (This setting is only available on day/night models of the
camera.)
Strobe = The camera will output a pulse on the output port that is synchronized to the start of

each image capture. This signal is useful for controlling things such as a strobe exposure lamp.
The Strobe Delay [µs] and Strobe Duration [µs] parameters (see below) are used to adjust the
characteristics of the strobe pulse.
Alarm Announce = The output port will "announce" an alarm condition. When an alarm

condition is declared, the port will become active. The port will remain active for the time period
specified by the Digital Output Hold Time [ms] parameter (see
For this function to operate correctly, the Action Enable box must be checked on the Digital
Output tab in the Alarm Actions section of the Alarm Handling parameters (see
Invert
- Determines whether the operation of the port in regard to being active or inactive will
operate normally or be inverted.
Unchecked = The port will operate normally.

Checked = The operation of the port will be inverted.

See Table 3 on page 85
State
- If the Direction parameter (see above) for the port is set to "Input", the State check box will
be read only and will indicate the state of the input port. Checked means active and unchecked
means inactive.
If the Direction parameter (see above) for the port is set to "Output" and the Function parameter is
set to "User Output", the State check box can be used to set the state of the output port. Checking
the box makes the port active.
Strobe Mode
- If the Function parameter is set to "Strobe", the Strobe Mode parameter allows you
to choose between two different ways of controlling strobe lighting. This is necessary because,
depending on the model, Basler cameras employ sensors with different shutter mechanisms, i.e.
global shutters or rolling shutters. To find out what kind of shutter your camera has, refer to the
