34 Basler sprint Mono Cameras
2.8 Output Signals
Data is output from the camera in accordance with the Camera Link standard. The camera’s output
signals include pixel data qualifiers such as line valid and data valid, pixel data, a Camera Link clock
signal, and a SerTFG signal.
2.8.1 Line Valid Bit
As shown in Figure 14 on page 32, a line valid (LVAL) bit is assigned to the Tx24 pin on the X, Y,
and Z Camera Link transmitters as defined in the Camera Link standard.
The line valid bit included in the video data output from the camera indicates that a valid line is being
transmitted. Pixel data is only valid when this bit is high. For more detailed information about the
line valid bit, see Chapter 5 on page 85.
2.8.2 Data Valid Bit
As shown in Figure 14 on page 32, a data valid (DVAL) bit is assigned to the Tx26 pin on the X, Y,
and Z Camera Link transmitters as defined in the Camera Link standard.
The data valid bit included in the video data output from the camera indicates that valid data is being
transmitted. Pixel data is only valid when this bit is high. For more detailed information about the
data valid bit, see Chapter 5 on page 85.
2.8.3 Pixel Data Bits
Pixel data bits are transmitted via output ports on the X, Y, and Z Camera Link transmitters. The
ports as defined in the Camera Link standard are shown in Figure 14 on page 32.
The assignment of pixel data bits to output ports varies depending on the video data output mode
of the camera. The available video data output modes and the bit assignments are explained in
detail in Chapter 5 on page 85. The bit assignments comply with the Camera Link standard.
The tables also show the assignments for the line valid bit, the data valid bit, and the pixel clock.
These assignments are constant for all output modes.
