Page 4: Applications
The FFM4027D/Multi is designed to take advantage of the sensor’s multi- output capability. For example, multiple analog processors and digitizers can be incorporated and the digital processing features (LUT, column substitution) can be programmed uniquely for each output. However, the current version of the camera Narragansett Imaging www.nimaging.com... - Page 5 USER’S MANUAL & REFERENCE GUIDE: FFM4027D/Multi utilizes only a single sensor output. Please contact Narragansett Imaging to discuss multiple-output applications. Figure 1. FTF4027 Structure The sensor data sheet contains detailed information regarding the sensor. Abridged specifications are presented below. Narragansett Imaging...

Page 7: Camera Specifications And Operating Conditions
An embedded microcontroller controls all aspects of the camera’s operation and provides the camera’s interface to the Camera Link serial channel. Electronics The following figure illustrates the basic design of the FFM4027D/Multi. Narragansett Imaging www.nimaging.com... - Page 8 Processed and multiplexed data from the Timing board passes to the Power Board’s Camera Link interface. Synchronization signals to/from external equipment are sent/received via the Power Board, as well. The following figure illustrates the video processing functions. Narragansett Imaging www.nimaging.com...
- Page 9 This facilitates custom applications and future feature enhancements. The Windows application provided by Narragansett Imaging includes this facility. The Power Board includes the Camera Link transmitter and connector, +12 volt (nominal) input power connections, +5 and +3.3 volt power supplies, and connections for external I/O.

Link serial interface. This is described in the document FFM3020D/Multi Hardware Manual and Programmer’s Guide. The protocol is compatible with Camera Link serial port drivers offered by frame grabber manufactures. Narragansett’s FFM/Multi Windows application currently works with National Instruments and Bitflow frame grabbers. -
