AW00098504000 I/O Control
Basler ace Camera Link 49
6 I/O Control
This section describes how to set the camera’s input and output lines. It also provides information
about monitoring the state of the input and output lines.
6.1 Input Lines
6.1.1 Available Input Lines
The camera is equipped with one GPIO line designated as line 1. The GPIO line can be accessed
through the four pin connector on the back of the camera as described in the "Physical Interface"
chapter. The GPIO line can be set to operate as either as an input line or an output line. This section
describes using the GPIO when it is set to operate as an input line.
The camera is also equipped with three input lines built into the Camera Link interface. These lines
are designated as CC1, CC2, and CC3 as specified in the Camera Link standard. Typically, input
signals are applied to these lines by the frame grabber board attached to the camera. The frame
grabber board can typically be configured to supply different types of signals to these inputs as
required by the camera user.
For more information about using CC1, CC2, and CC3 on the specific type of frame grabber
installed in your system, refer to the documentation for your frame grabber board.
You can also get some general information about how these lines are implemented in the Camera
Link interface from the Basler document called Ace Camera Link Information for Frame Grabber
Designers (AW000990xx000). You can obtain the document from the Downloads section of the
Basler website: www.baslerweb.com
6.1.2 Setting the GPIO Line to Operate as an Input
The Line Mode parameter is used to set the camera’s GPIO line to operate as an input.
For more information about the electrical characteristics of the GPIO line, see Section 5.7 on
page 35.
NOTICE
Applying incorrect electrical signals to the camera’s GPIO line can severely damage the camera.
1. Before you connect any external circuitry to the GPIO line, we strongly recommend that you
set the GPIO line mode so that the line will operate as an input.
2. Once the line mode is set, make sure that you only apply electrical signals to the line that are
appropriate for the line’s current mode.
