ExSync Programmable Mode Exposure Start with Frame Valid High Whenever a frame is being transferred regularly discharge pulses are generated If ExSync rises while a frame is being transferred it is not possible to generate a discharge pulse asynchronously In this case the start of exposure is shifted to the end of the last regular discharge pulse The discharge pulses during exposure are suppressed The microcontroller detects the shift in the start of exposure and it makes a corresponding shift in the end of the exposure The end of the shifted exposure triggers readout Readout occurs after a delay of 10 us Readout takes 5 us during which exposure continues Effective exposure 15 0 us n Timer 1 FVAL must be low for at least 1 ns before the end of the shifted exposure ExSync must remain high for a minimum of 1 us The minimum ExSync signal period is 33 3 ms With very low exposures use flash light to prevent smearing 3 10 BASLER 201 Basic Operation and Features 3 3 5 Free run Programmable Mode with Exposure Start After Image Transfer Frame Valid Low control signal period Internal Contro Exposure m Signal Timer 1 dt M 36 5 us gt 32 ns gt PA 1421 5 us This timing diagram is Frame E rg not drawn to scale Valid x ii Ce 437 5 us 1016 1017 1018 Line Valid effective

32. The desired 15 dB default gain is achieved when the gain is programmed to 376 0x0178 You should find that the default gain setting on your camera is near to this value Reducing the gain below 376 results in mapping more than the linear operating range of the sensor to the ADC Increasing the gain to more than 376 maps a smaller portion of the sensor s linear output signal to the ADC If you know the decimal number DN setting for the gain on your camera the equivalent decibel value can be calculated by using one of the following two equations 658 DN dB 20 0910 658 3 7 Where DN 0 to 511 dB 0 0354 DN 3 79 Where 512 to 1023 BASLER 201 Basic Operation and Features 3 5 2 Balancing the Gain and Offset on Odd and Even Lines Internally the 201 processes odd and even lines separately in two different data channels see Figure 3 1 Consequently the gain and offset must be adjusted separately for the odd lines and for the even lines Due to variations in the camera s electronics the gain and offset needed to correctly map the output from the odd lines to the odd channel ADC may be different from the gain and offset needed to map the output from the even lines to the even channel ADC Gain alignment between the channels is important to maintain uniform output data with minimal gray value differences between odd and even lines Basler performs a calibration procedure on each camera before it leav
