Physical Interface34 Basler sprint Mono Cameras2.8 Output SignalsData is output from the camera in accordance with the Camera Link standard. The camera’s outputsignals include pixel data qualifiers such as line valid and data valid, pixel data, a Camera Link clocksignal, and a SerTFG signal.2.8.1 Line Valid BitAs 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 beingtransmitted. Pixel data is only valid when this bit is high. For more detailed information about theline valid bit, see Chapter 5 on page 85.2.8.2 Data Valid BitAs 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 beingtransmitted. Pixel data is only valid when this bit is high. For more detailed information about thedata valid bit, see Chapter 5 on page 85.2.8.3 Pixel Data BitsPixel data bits are transmitted via output ports on the X, Y, and Z Camera Link transmitters. Theports 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 modeof the camera. The available video data output modes and the bit assignments are explained indetail 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.
