54 Basler ace Camera Link
6.2 Output Lines
6.2.1 Available Output 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 output line.
The camera is also equipped with a CL Spare data bit built into the Camera Link interface as
specified in the Camera Link standard. On ace Camera Link cameras, the CL Spare data bit can be
used as a camera output line.
You can get some general information about how this bit is implemented 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
6.2.2 Setting the GPIO Line to Operate as an Output
The Line Mode parameter is used to set the camera’s GPIO line to operate as an output.
For more information about the electrical characteristics of the GPIO line, see Section 5.7 on
page 35.
The CL Spare data bit is not available when the camera is set for the 1X8-1Y or
the 1X10-1Y tap geometry.
The CL Spare data bit is not directly accessible by the camera user. The data bit
must be accessed via the frame grabber attached to the camera. Not all frame
grabbers provide users with direct access to this bit. Consult your frame grabber
supplier for more information.
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 output.
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.
