6 Chapter 1: Introduction Matrox CronosPlus Matrox CronosPlus is a standard monochrome and composite color analog frame grabber for extremely cost-sensitive imaging applications. This board is available in a PCI form factor and can acquire different types of standard video formats using its video decoder.
4 user output TTL signals. Data transfer The Matrox CronosPlus board allows the transfer of live video to Host memory or off-board display memory. Matrox CronosPlus also features a 32-bit/33 MHz PCI bus master to reduce CPU usage. The board can also generate interrupts for the start and end of a field, frame, and sequence capture.
• Microsoft Windows if using Matrox Imaging software (consult the documentation accompanying the software for specific supported environments and computer memory/storage requirements). ❖ Matrox CronosPlus is not supported under Windows NT. • A CD drive, and a hard disk or network drive on which to install the Matrox CronosPlus software.
5 BNCs and open-ended wires on the other end. Handling components The electronic circuits in your computer and the circuits on Matrox CronosPlus are sensitive to static electricity and surges. Improper handling can seriously damage the circuits. Be sure to follow these precautions: •...
Appendix A. 2. Complete the software installation procedure as described in the documentation accompanying your software package. For information on using multiple Matrox CronosPlus boards, refer to Chapter 4, More information and for in-depth hardware information, refer to Chapter 5.
Matrox CronosPlus board. Five empty (32-bit) PCI slots are illustrated below: 3. If present, remove the blank metal plate located at the back of the selected slot. Keep the removed screw; you will need it to fasten the Matrox CronosPlus board.

Installing Matrox CronosPlus 4. Carefully position Matrox CronosPlus in the selected PCI slot. 5. Once perfectly aligned with an empty slot, press the board firmly but carefully into the connector. 6. Anchor the board by replacing the screw that you removed.
Connecting external devices to Matrox CronosPlus Matrox CronosPlus has the following connectors on its bracket. The pinouts of these connectors are discussed in detail in Appendix B. • BNC connector. Used to receive CVBS video input 0 or the Y component of Y/C video input.

Connecting external devices to Matrox CronosPlus The wires of the cable for video input are listed in the following table: Wire label Signal Expected input CH-0 VID_IN0 CVBS video input 0 or Y component of Y/C video input. CH-1 VID_IN1 CVBS video input 1.
(refer to Chapter 2). In other words, place each additional board in an empty slot. Theoretically, you can have as many as 16 Matrox CronosPlus boards installed in your computer at one time; this number is, however, limited by the number of empty slots in your computer and, for simultaneous grabs, by the available bandwidth of your computer (discussed later in this chapter).

PCI bandwidth of 35 Mbytes/sec or 42 Mbytes/sec, respectively, when transferring in RGBX (32-bit) mode. When grabbing from three or more Matrox CronosPlus boards simultaneously, you will have to reduce the image size to avoid reaching the upper limits of the...

Matrox CronosPlus hardware reference This chapter provides information on the architecture, operating modes, and supported features of Matrox CronosPlus. For a summary of the information given in this chapter and detailed specifications of connectors and pinouts, refer to Appendix B of this manual.
Grab features Grab features The Matrox CronosPlus board is equipped with a video decoder chip that has an integrated PCI interface. The chip can grab RS-170 /CCIR monochrome video and composite (CVBS) and component (Y/C) video in NTSC /PAL format.
Low-pass filter The input low-pass filtering stage is used to limit high frequency noise and aliasing effects at the input of the decoder. The filters used on Matrox CronosPlus are 4th order Butterworth filters with a cut-off frequency of 8 MHz.
Electrical specifications in Appendix B. PCI interface Matrox CronosPlus has a 32-bit PCI bus interface, which is capable of a peak transfer rate of 132 Mbytes/sec, and operates at 33 MHz. Matrox CronosPlus uses an internal FIFO to buffer image data while waiting to access the PCI bus.
Appendix A: Troubleshooting This appendix gives suggestions to help you resolve potential problems. If your problem is not addressed here, contact your local Matrox representative, Matrox Sales Office, or the Matrox Imaging Customer Support Group.
Installation Problems ➘ You receive a "Board service fails to start" error upon booting your computer, or you receive a "Driver has not started" error upon allocating a MIL CronosPlus system. This could happen due to the following three reasons: - The MIL Matrox CronosPlus drivers are not installed correctly.
Resources folder. Then, display the subfolder \Memory to check if any of the memory address ranges overlap. After, in the case of Me, display the subfolder \IRQs to check for devices that are sharing an IRQ with your Matrox frame grabber. In general, PCI devices can share an interrupt line (IRQ). However, sometimes this might not be possible.
30 Appendix A: Troubleshooting - Re-assign a different IRQ line to the PCI slot in which the Matrox CronosPlus board is installed. Note that PCI devices cannot share interrupt lines with EISA or ISA devices. - Move the Matrox CronosPlus board to another (free) PCI slot.
(or equivalent) or better. Some older systems use a core logic chipset (interfaces PCI with Host memory) that has limited throughput capabilities. Matrox CronosPlus might not be able to attain full functionality on such systems. We recommend systems with newer PCI chipsets, such as the Intel 440BX, 810, 815E, 820, 840, or 850.
