Basic Operation and Features3-6 Basler A500k SeriesPRELIMINARYFigure 3-7: Free-run, Programmable Mode• In free-run, VGA mode (A504k/kc only), the camera generates a continuous internal controlsignal which is set to 60 Hz and can not be varied. The data is output at the VGA monitor out-put connector and at the Camera Link connectors. Timer 1 determines how long the internalsignal will remain low. Pixels are exposed and charge is accumulated when the internal con-trol signal is low. In this mode, the exposure time can be programmed as desired by varyingthe setting of the “Timer 1” parameter.The minimum exposure time is 10 μs.Also see section 2.5.8 for a description of the VGA monitor output mode.If you want to operate the camera at maximum exposure and maximum frame rate, see section3.5 for further setting recommendations.You can set the camera to operate in free-run using either the Camera Configuration Tool Plus(see Section 4.1) or binary commands (see Section 4.2).With the Camera Configuration Tool Plus, you use the Exposure Time Control Mode command toset the camera for free-run and to select the edge-controlled or programmable exposure timecontrol mode. If you choose to operate the camera in free-run, the configuration tool will requireyou to enter a frame rate; if you are using the programmable mode, you must also enter anexposure time. The configuration tool will automatically set the Timer 1 and Timer 2 parametersbased on the values that you enter on the Exposure Tab.With binary commands you must use the Exposure Time Control Mode command to select thefree-run, programmable or free-run, VGA mode. You must also use the Timer 1 command to setTimer 1 and the Timer 2 command to set Timer 2.* In the free-run programmable mode, the period of the internal control signal isequal to the sum of Timer 1 plus Timer 2. The sum of the Timer 1 setting plus theTimer 2 setting must be greater than the maximum frame rate.The minimum exposure time is 10 μs.Timer 1 Timer 2ExposureFrame read outControl Signal PeriodInternalControlSignalTimer 1 Timer 2ExposureFrame read outControl Signal PeriodInternalControlSignal= 60 Hz |
