6 Camera Basics
Figure 39: Triggered image capture and flash with delay and duration
The delay is due to internal camera switching times and depends on the sensor type and
the parameters that have been set. It is always below 100 µs. You can find the exact values
for each camera in the Specifications: Sensors chapter. You can set an additional delay
and the duration of the flash signal in the software.
The settings specified for the digital output will be reset in the following situations:
·
a
GigE uEye
camera loses its pairing (i.e. it is closed in the software)
·
a
USB uEye
camera is disconnected from the PC or the PC is powered down
6.5.3
General Purpose I/O
Some uEye models have freely programmable General Purpose Inputs/Outputs (GPIO) which can be
programmed as inputs or outputs using the
uEye
SDK
(see also GPIO Specifications).
The GPIO settings will be reset when the camera is closed in the software.
6.5.4
Serial Interface (RS232) of the GigE uEye HE
Cameras of the
GigE uEye HE
series are equipped with a serial interface (RS232). It provides
functionality for communication with peripheral devices (e.g. lighting controller, lens controller) or the
serial port of a PC. Before you can send data through the camera's serial interface, one or more
virtual COM ports have to be defined on the PC. Once defined, they can be used for data
communication with appropriate software just like any physical COM port.
To set up and use the serial interface, the
Additional functions dialog box is provided
in the
uEye
Camera Manager
. For the serial interface specifications, please refer to the Serial Interface (RS232)
chapter.
