  • Page 4: Overview

    OVERVIEW OVERVIEW The picasso cPCI-LS is a high-performance ‘plug and play’ PC-card for the CompactPCI-bus. It enables each standard CompactPCI system to capture and store single images for image processing. The picasso cPCI-LS operates as a CompactPCI bus master, allowing it to transfer images directly to the system memory without impacting the processor.

  • Page 5: Features

    68-pin AIA-standard connector RS-644 (LVDS) or RS-422 The inputs/outputs are compatible with RS-644 (LVDS) or RS-422 signaling levels. Ask ARVOO Support for more information. Exposure time Exposure is programmable from 6.375µS to 419 mS. The exposure output can be active low or active high. LED indicating status exposure outputs.

  • Page 6: Getting Started

    A mouse or compatible pointing device. One CD-ROM drive for installation. ARVOO recommends systems with newer PCI-chipsets, such as the Intel 440BX, i810,i815 or i820. The maximum data-rate of the pci-bus is 132 MB/s. This is without latencies or its bus protocol.

  • Page 7: I/Oconnectors

    The AIA connector is the same as the SCSI2 connector. For the male connector ARVOO advices a AMP SCSI2 connector, part number: 749109 or 749621-7. The shell housing part number: 750752 or 749204-2.

  • Page 9: Exposure Header

    GETTING STARTED 1.3.2 Exposure header The exposure outputs on the AIA-connector can be used in two ways: Software triggered. Hardware triggered via exposure header. Software or hardware triggered is software controlled. EXPO0 can be used in two ways in bought modes, EXPO1 only in operating MODE 1. EXPO1 has the function of a general purpose output in MODE 0.

  • Page 11: Lvds General Purpose Input/Output

    GETTING STARTED 1.3.4 LVDS General Purpose Input/Output On the AIA-connector there are some RS-644 or RS-422 signals which have a general purpose function. In Table 1 the pinout of the AIA connector in MODE0 and MODE1 is given. In MODE0 the following signals are general purpose input: PSTRB1, LEN1, FEN1 and SDI. In MODE1 only the SDI signal is input.
  • Page 12 GETTING STARTED ATTENTION: When the computer is turned off and the external power supply stays up the output will also be forced to ground. In Figure 5 a wiring example for an output is given. External 5V Imax 100 External power supply picasso...

    FID1(optional), PSTRB1. EXPO0 is for camera A, EXPO1 is for camera B. FID and FID1 are optional, ask ARVOO Support for more information. Both modes can acquire images up to 4096 pixels per line by 4096 lines per frame (4 million pixels maximum).
  • Page 14 OPERATION PRINCIPLES PCI-bridge The picasso cPCI-LS is a full PCI 2.1 master with a transfer rate up to 132 Mbytes/sec. It has a 5V or 3.3V I/O signaling environment. Support of zero wait state burst transfers. By specifying starting pixel, line locations and size an region of interest can be selected. The user has to specify both the source and target fields.
