OVERVIEW
OVERVIEW The picassoTM PCI-3C is a high-performance ‘plug and play’ PC-card for the PCI-bus. It enables each standard PCI system to capture and store single images for image processing or full-frame display of real-time video in a window (30 frames/sec). The picassoTM PCI-3C operates as a PCI bus master, allowing it to transfer images directly to the system or VGA memory without impacting the processor. The picassoTM PCI-3C has two analog RGB inputs with separate sync inputs. Sync is also accepted on one of the color inputs. The video input is software controlled and accepts both standard and non-standard video signals. Progressive scan and line scan video formats are optionally supported. The grabber is also designed as a triple channel 8-bit digitizer for monochrome video (three synchronized B&W cameras). The picassoTM PCI-3Cpro supports additional acquisition from CVBS video signals. The 3Cpro CVBS inputs are software controlled and accept NTSC and PAL video formats.
FEATURES
FEATURES n 32-bit PCI interface, 3.3V or 5V I/O compatible The picassoTM is a full PCI 2.1 bus master with a transfer rate up to 132 Mbytes/sec. This allows the bus master to transfer up to 30 frames/sec. Support of zero wait state burst transfers. n Two RGB colour/multiple monochrome video inputs Several configurations are possible, selected by software. Two RGB cameras, one active. Two pairs of 3 synchronised monochrome video inputs. The picassoTM PCI-3Cpro supports four additional CVBS (composite colour) video inputs or two S-Video inputs. n Resolution 24 bit color levels. Standard square pixel format with 768/640 active pixels resolution per frame. NTSC, PAL, SECAM, interlaced or progressive scan. The maximum sample frequency is 20MHz. n RS-170 CCIR 601 level-compatible n Square pixel – 1:1 aspect ratio n Memory Memory Management Unit (MMU) supports Virtual Memory up to 4 Mbytes/DMA channel. n Data Formats RGB digital Video can be stored in several formats (RGB565, RGBα555, RGB55α5, RGB24) in system memory or the displays adapter frame buffer. CVBS digital video can be stored as RGB32, RGB24, RGB15, RGB8, YUV444, YUV422, YUV411, YUV8 and YUV8-GRAY n Two digital inputs and two digital outputs The picassoTM has two optical isolated digital inputs and outputs. They are software controlled and they can be used for external events such as light switching and camera triggering. The inputs can be programmed as interrupt for fast input reaction time.

GETTING STARTED
1. GETTING STARTED 1.1 Hardware Requirements The following minimum system characteristics are required by the picassoTM . n n n n n
IBM PC or compatible with Pentium 266MHz (or better). One available PCI version 2.1 bus master expansion slot (32-bits, 3.3V or 5V I/O). 32 Mbytes of DRAM. A mouse or compatible pointing device. One 3.5 inch floppy disk drive for installation.
ARVOO recommends only motherboards that are equiped with modern PCI-chipsets, good test results have been found with e.g. the Intel 440BX, i810, i815 or i820 chipsets. 1.2 Installing the picassoTM 1. Select a 32-bit PCI bus master expansion slot. Refer to your computer systems user manual to determine which slots are bus masters. 2. Remove the metal bracket. 3. Before handling the board, discharge any static build up on your body by touching the metal case of the computer. Remove the board from its bag and hold the picassoTM by its top edges and do not touch its components. 4. When the bottom of the board contacts the bus connector, gently press down on the board until it is fully seated. Secure the board using the removed screw from the slot cover. TM 5. Connection of the video signal to the picasso is accomplished using a standard VGAconnector (15 pins SUB-D).

GETTING STARTED 1.3 I/O connectors
Figure 1 1.3.1 Video sources The picassoTM PCI-3C supports two RGB video sources or six B&W. The picassoTM PCI-3Cpro supports two RGB, six B&W, or four CVBS (composite colour) video sources. The selection of the different video inputs is software controlled. The green LED (D1) [see Figure 1] indicates locking of the frame grabber on an incoming video signal. When the green LED is flashing it indicates an error condition: - Video input signal doesn’t contain sync timing. - Wrong selection of video standard (PAL instead of NTSC). - Wrong selection of sync input (sync on red instead of sync on green) When the green LED doesn’t light-up at all, it indicates: - No video or sync signal. - Wrong video input-port selected (Y2 instead of Y1). The green LED doesn’t indicate lock information when you capture CVBS video signals with the picassoTM PCI-3Cpro.You can display or capture one camera at a time.

GETTING STARTED The video input-connector is a SUB-D15 connector and the GPIO is a SUB-D9 connector [see Figure 2].

Figure 2: Close-up of RGB-VID and GPIO connectors. Table 1 shows connection of the video sources to the SUB-D15 connector. The pin assignment depends on the video sources that are used. Four modes can be distinguished: (1) RGB mode for 3 component video, e.g. RGB or YUV. (2) Y-mode for B&W video. (3) CVBS-mode for CVBS composite video. (4) S-video-mode for S-video (Y/C) video.

GETTING STARTED The Composite SYNC OUT pin is TTL compatible and re-outputs the Composite SYNC IN (also when SYNC on component [green, red or blue] is selected) and can be used for camera synchronisation. 1.3.2 General Purpose Input /Output connector The General Purpose Inputs and Outputs are connected to the picassoTM by a SUB-D9 female connector. In Figure 4 you see a drawing of the SUB-D9 connector. The pin connections are listed in Table 2. Sub D-9 Input 0 Input 1 Output 0 Output 1 VCC (5V) GND

When you use the general-purpose inputs or outputs you have to connect an external 5V power supply. The maximum voltage is 5.5V and the input current is 10mA. When U19 and F1 is placed [see Figure 1] no external power supply is needed. U19 will provide the external 5V. F1 is a fuse with the following specifications: 250mA, fast. Ask ARVOO support for more information. ATTENTION: The maximum output current is 100mA. The outputs are open drain, which means that logic 1 will force the output to ground. A wiring example to connect an output is given below. ATTENTION: When the computer is turned off and the external power supply stays up the output will also be forced to ground.
