At this point, you are asked for the location of the corresponding *.inf file. Please click on the drive where the CD has been inserted or to the directory where the installation software has been downloaded. - Page 10 Chapter 1 Introduction page 10 After finishing the adjustments, tighten the two Allen screws. F-mount-adaptor Begin by loosening the Allen screw, which is in the hole of the knurled ring around the F-mount adaptor (close to the camera front plate). The distance between the lens sup- port plate and the image sensor can be changed by turn- ing the total F-mount adaptor.

Chapter 3 Camera Functions page 13 and reconnect it later. Further, the image memory in the camera enables (see Figure 3.1, pco.camera – camRAM) extended operating modes (e.g. ring buffer operation). In this mode, images are continuously recorded and, as the memory is filled, the oldest image data are overwritten. -

Various configurations are possible for the four memory segments to record various image formats, binning modes or ROIs. - Page 15 Chapter 3 Camera Functions page 15 camRAM Figure 3.5: Illustration FIFO buffer mode. If the camera reaches the end of the memory segment, it starts to fill the memory space from the start, which has been released due to image data transmission (see Figure 3.5).

During ring buffer operation, the memory segment is also filled up. Cyclical writing to the memory segment occurs if the camera reaches the end of the segment when it will overwrite the oldest images (see Figure 3.7). - Page 17 Chapter 3 Camera Functions page 17 auto sequence In the [auto sequence] exposure control mode, the cam- era determines the fastest possible image uptake rate de- pending on the adjusted delay and exposure times and the required readout time. After a start command is given, the sequential recording is started until a stop command is given.

Chapter 3 Camera Functions page 18 3.3.3 Time Lapse In this chapter the time-lapse feature is explained in de- tail. The following acronyms are used: Exposure time for one image (adjustable) Readout time for one image (from CCD-sensor) read (system inherent) Time delay between start-signal and exposure delay (adjustable) - Page 19 Chapter 3 Camera Functions page 19 delay read time Figure 3.10: Time lapse illustration of the image recording for the asynchronous image recording and delay time t > 0 mode. delay The arrows indicate the beginning of each image recording sequence (the times are not drawn to scale).

Page 30: Data Interfaces
Chapter 4 Data Interfaces page 30 Data Interfaces The pco.camera system is delivered with three interface options: Firewire 400 (IEEE1394a), Camera Link or Gigabit Ethernet. To determine which interface is implemented, please see the technical datasheet in the appendix of this manual. -
Page 31: Firewire 400
Chapter 4 Data Interfaces page 31 camera-API, itself, distinguishes between the different in- terfaces and accesses the IEEE1394 driver-stack. This stack uses an asynchronous serial data channel for the command and status information in both directions and an isochronous channel to transfer the image data from the camera. -
Page 32: Camera Link
Chapter 4 Data Interfaces page 32 • http://www.firewire-1394.com/ Camera Link Camera link is a point-to-point connection with a 200 – 1000 Mb/s bandwidth. The pco.cameras use the “base – configuration” (1 cable) which gives a transfer speed of 200 Mb/s at 66 MHz and 255 Mb/s at 85 MHz. The clock rate is selectable with camera commands. -

Page 34: Firmware Update
Chapter 5 Software page 34 Firmware Update The pco.camera system can easily be firmware updated by the user. It is done over the existing interface, with no special cables or other equipment needed. The update is done via the special programmer software, which is in- cluded in the firmware update zip-file package. -
Page 35: Service And Maintenance
Chapter 6 Service and Maintenance page 35 Service and Maintenance Service The camera is designed to be maintenance-free with no adjustments or inspections needed. Camera Maintenance Unplug the camera from any power supply before cleaning Use a soft, dry cloth for cleaning the camera. Do not use liquid cleaners or sprays. - Page 36 Chapter 6 Service and Maintenance page 36 Every time the input window is cleaned, there is the pos- sibility of surface damage. Do not clean the input window unless it is absolutely necessary. Be careful and avoid scratches and damage to the input window surface. Do not use a dry cloth to clean the input window.
