    Camera interfaces Synchronization output (pin 6) Note Only cameras with firmware CMC.040.01.07 or newer support this feature.  If you use a camera with an older firmware version: don‘t con- nect pin 6. Use this signal for the following: • Synchronize external devices to the effective exposure of Bonito.

  • Page 27: Trigger Input (Pin 10-11)

    Camera interfaces Trigger input (pin 10-11) Figure 11: Trigger input diagram The current through the optocoupler’s LED should be in the range from 5 mA to 15 mA. This is the case if 5.0 V ≤ V ≤ 12 V. Note If you use higher voltages, you have to connect externally an additional current limiting resistor.

  • Page 28: Reserve I/O (Pin 5, 9 And 14-15)

    Camera interfaces This is an open collector optocoupler output. The transistor is conductive during the active exposure time of the image sensor. The optocoupler adds an intrinsic delay to the signal. The power dissipation through the optocoupler’s transistor must not exceed 150 mW.

  • Page 29: Camera Link Interface (01-04 Or Cl1, Cl2)

    Camera Link interface (01-04 or CL1, CL2) Camera Link interface (01-04 or CL1, CL2) Camera Link is an interface for the transmission of digital video data. The stan- dard defines data transfer on a physical base and determines connectors, cables and components for transmission and reception.
  • Page 30 Camera Link interface (01-04 or CL1, CL2) Each channel delivers ten Camera Link ports labelled A to J. Every port has eight bits and is assigned to a corresponding sensor tap that outputs specific pixel columns of the image. Consequently, up to 2 x 10 = 20 simultaneous pixels are transferred to the frame grabber(s) in parallel per Camera Link clock cycle.

    Camera Link interface (01-04 or CL1, CL2) functions. Both Camera Link serial interfaces (and also the third RS-232 inter- face at the 15-pin D-sub connector) are virtually equal. They all use one global baud rate setting. They also share the same receive buffer. Output characters (including echo) are always sent to all activated serial ports.

  • Page 33: Reserve Control Input (Cc2)

    Camera Link interface (01-04 or CL1, CL2) Reserve control input (CC2) The camera control signals CC2 at the Camera Link connectors O2 and O4 (or connector CL1) are reserved for future use. Pixel order Each frame in single channel mode (S=0, max. 193 full frames per second) is transmitted from top left to bottom right, line per line.
  • Page 34 Camera Link interface (01-04 or CL1, CL2) From the host’s point of view the Bonito behaves like two cameras with half of the possible image width. The host computer receives two images at the same time that are reconstructed in the order shown below. It is the duty of the sys- tem designer to allow for assembly of the two halves if the application demands Figure 16: Pixel order: half frame Bonito Technical Manual V2.3.0...

  • Page 35: Timing (Fval, Lval, Pclk)

    Camera Link interface (01-04 or CL1, CL2) Timing (FVAL, LVAL, PCLK) The Camera Link pixel clock frequency of the Bonito is 80 MHz. The 10-tap configuration transfers 10 pixels per clock cycle at once, or 20 pixels per clock cycle in the dual-channel mode). The synchronization signals LVAL (line valid) and FVAL (frame valid) are used to designate valid data output.

The frame gap may vary in other trigger modes. Additionally, the number of active lines per frame can be config- ured by the user (parameter N).

    Camera Link interface (01-04 or CL1, CL2) Dual channel, reduced line length The charts below illustrate the Camera Link timing for dual channel mode (com- patibility mode with reduced line length, S=3), in continuous mode (M=0).

  • Page 45: Timer Prescaler Value (K)

    Parameters and commands Timer prescaler value (K) The prescaler value is used to divide the basic timer clock frequency of 56 MHz by a value of (K + 1) down to a smaller clock frequency. The resulting frequency is utilized as the time base for exposure time E and frame duration F. This parameter is 16 bit wide.

  • Page 47 Parameters and commands Since all of the sub-fields are set using the parameter M, it is only possible to set all of them at the same time. The value of M is calculated as the aggregate sum of the hexadecimal values that are set to each of the three sub-fields. The table below shows the hexadecimal weights that can be set for each sub- field.

  • Page 52 Parameters and commands Basic working principle of the CMOS sensor A basic understanding of the CMOS sensor‘s working principle is required to understand how the PIV mode of the Bonito operates. For that reason, a simpli- fied short explanation is included below.

  • Page 54 Parameters and commands Internal charge transfer and readout The internal charge transfer of the first image is started with some fixed delay and it takes the time of one line duration (t ). The end of the charge transfer effectively terminates the exposure of the first PIV frame and internally starts exposure of the second PIV frame.
  • Page 55 Parameters and commands The rising edge at synchronization output signalizes externally that the expo- sure of the first PIV frame has ended. This requires setting J=1, and may be used to trigger the second flash pulse. The recommended guard interval t will be kept automatically.
  • Page 56 Parameters and commands Sets the Exposure feature mode to Standard. (weight = 0) • Even though the Exposure feature mode is set to Standard, not to Perma- nent Exposure mode, the exposure is always active, due to activation of the PIV mode. (0x7 = 0b111), sets the bit field to „- - 0 0 - 1 1 1“.
