Hardware triggering and scanning with both, the Retiga 2000R and the Dalsa HS-40-04K40 camera. The encoder signal of Newport’s LTA-HS servomotor in x-direction of the ESP 301 motion controller is bypassed over a custom made card and an RS422-to-TTL converter and goes to a National Instrument NI PCIe – 6321 Counter/Timer/Trigger Card. This card is programmed to divide the rising edge of the received signal by a constant factor and the result is an output signal. The signal triggers the Retiga 2000R and the Dalsa HS-40-04K40 by a connection to the camera’s trigger input channel.
