18 Trillium User’s Manual 2.5 RS232 Inputs This allows you to trigger camera functions from your frame grabber or other controller. User2, User3, User4 (RS232) These signals are user-configurable single-ended inputs with RS232 thresholds. They can be used to trigger camera functions that have been previously programmed through the serial interface. This allows you to trigger camera functions from your frame grabber or other controller without connecting to a PC. The camera accepts RS232 inputs on a standard DB9F connector. See Appendix C for protocol and command structure details. 2.6 Pushbutton Input The camera’s pushbutton, located on the upper left corner of the backplate, triggers software commands. The factory default setting is a white light calibration (equivalent to the command correction_calibrate 2). The button’s function can be customized to any command through the serial interface. See Chapter 3 for details. 2.7 Iris Control Outputs 2.8 Data Outputs The camera's 6-pin iris control connector is designed to output control signals to a motorized iris. The camera has an embedded controller that can adjust lens aperture from a maximum of f/1.4 to f/22.4 assuming the use of a DALSAsupplied 1K lens. The 2K lens aperture range is f/2 to f/16. See section 2.3 for pinouts. Digital Data The camera uses 10-bit ADCs and outputs the most significant 8 bits (one channel for each color) in LVDS format. To clock digital data into the frame grabber, use the camera outputs clocking signals STROBE and LVAL. IMPORTANT: This camera’s data is valid on the rising edge 03-32-10119-03 of STROBE. DALSA
