• analog, digital, IEEE1394a and Camera Link frame grabbers available
• extensive choice of standard and non-standard cameras
• PC-Card interface available for add-on custom functionality
• remote boot from LAN

MainBoard

The LVmPC series is based on standard notebook components with the following specifications:

• MainBoard based on Intel 815E standard-chipset.
• Processor choice of Intel PIII 933 MHz with 512K cache or Celeron 650 MHz with 256K Cache, using advanced 0.13 micron process technology. As Ultra Low Power Processors, the power consumption and therefore the heat dissipation is extremely low. They belong to the Intel Embedded Roadmap and are long-term available. An OEM version with a 478-pin socket enables the use of other Low-Cost / High performance CPU's.
• 64-bit 512 MB SDRAM as a single SO-DIMM, 144 Pin, 68 mm×2.7 mm.
• Integrated 3D graphics controller chipset with up to 1280×1024×24-bit resolution with DVI-I connector for standard digital TFT monitors, as well over an adapter plug for standard analog monitors.
• 2 × USB type A (for OEMs there is an option of 2 additional USB type A), COM1, COM2 (internal), PS/2-keyboard, PS/2-Mouse, IDE, all with standard connectors accessible from outside the cabinet.
• 10/100 Mb Ethernet Controller.
• IEEE1394 FireWire Interface for Digital cameras etc. (for OEMs there is an option of 1 additional IEEE1394a FireWire Interface).
• Up to 4 PMC slots for PicPort^® or PicProdigy^® frame grabbers and other I/O modules from Leutron Vision (OEMs may integrate a third party PMC module supporting 3.3V PCIbus).
• State of the art standard BIOS, 100% compatibly with PC-Standard.
• Boot from USB device or remote boot from LAN.
• 2.5" IDE hard-disk with mounting size of 9.5 mm thick.
• 2 slots for Compact Flash Type I/II (50 Pin ATA-Interface) enable the use of up to 2 GB of resident flash memory (as a replacement for the hard-disk).
• DC/DC converters enable the use of a single 12 or 24 VDC power supply.

Frame Grabber Modules

• To connect cameras for medical, security and industrial machine vision applications, LVmPC offers different PMC frame grabber modules as well as a IEEE1394a interface on the motherboard. Supported are analog standard cameras (CCIR, RS170) and non-standard video sources (high-resolution, high-speed, dual tap, etc) as well digital interfaces (CameraLink, RS-422, RS-644, IEEE1394a, etc). These frame grabbers offer many possible configurations for almost all image acquisition needs like simultaneous acquisition from several cameras, image processing and bayer pattern decoding in realtime, or random reset control of cameras. Image data is transferred by DMA over the PCIbus direct into the CPU memory and/or into the graphics card memory. A hardware state-machine on each frame grabber guarantees the performance of realtime critical functions independent of the operating system.
