DCF Interfacing non-standard cameras to Matrox Pulsar Phillips FTM12 2. [. . . ] Control Mode · Application Note: February 7, 1996 IMG-7W2-TO-5BNC cable and PLS-TTL-CABLE required continued Video input BNC of IMG-7W2-TO-5BNC cable should be connected to VIDEO OUT BNC connector of camera Camera must be configured in non-interlaced mode The connections between the DB-37 connector of the PLS-TTL-CABLE and the 25-pin sub/D connector of the camera are the same as those in Continuous mode: Submode 3. The connection between the trigger input of the camera and the exposure output of the Pulsar is now used to send asynchronous reset and exposure signals to the camera TTL external trigger source should be connected to the TTL Trigger Input of the IMG7W2-TO-5BNC cable · · · · 4. Continuous Mode: · A table of integration time settings for the Continuous mode can be found in appendix 2 of the User Manual for the FTM12 camera 5. Trigger Mode: · Once it has received the external signal to trigger, the Pulsar sends a TTL exposure signal to the camera. The camera awaits the rising edge of the signal, at which point it initiates exposure. The exposure time is set on the camera by using the camera control software · A table of integration time settings (for both ranges 1 and 2) for the Trigger mode can be found in appendix 3 of the User Manual for the FTM12 camera · An exposure pulse going high before the integration period has ended will result in a charge reset; the integration time counter resets and starts again from zero · Minimum duration of an exposure pulse must be 3. 2µs Special Considerations 3. Control Mode: Once it has received the external signal to trigger, the Pulsar sends a TTL exposure signal to the camera. The camera awaits the rising edge of the signal, at which point it initiates exposure. The exposure time is set by the Pulsar; the camera will expose for as long as the exposure signal is high · When the exposure pulse goes down, frameshift will start. If there is an exposure pulse before the complete storage part is read out, the rest of the image will be lost and the sequence starts again. Using this feature it is possible to get a higher frame rate if part of the image is not needed · PUL-CID-006 4 Interfacing non-standard cameras to Matrox Pulsar Phillips FTM12 February 7, 1996 Application Note: Special Considerations · · Exposure time can be modified using Matrox Intellicam. Consult the Matrox Intellicam User Guide for more information Default exposure time is 10ms The DCF(s) mentioned in this application note can be found on the MIL and MIL-Lite CD, or our FTP site (ftp. matrox. com).
