General features
Lookup tables
Matrox Meteor-II /Multi-Channel has three 256x8-bit input lookup tables
(LUTs), allowing independent re-mapping of three 8-bit input streams.
The LUTs on the Matrox Meteor-II /Multi-Channel for PCI support RGB 8:8:8
(24-bit) output pixel formats. The LUTs on the PC/104-Plus form factor support
RGB 8:8:8, RGB 5:6:5, and RGB 5:5:5 output pixel formats. LUTs are
programmed using the MIL-Lite command, MdigLut().
User bits
Matrox Meteor-II /Multi-Channel supports four auxiliary TTL user bits through
the video input connector: two inputs and two outputs. These are available for
controlling external events such as a strobe light or PLC. User bits are programmed
using the MIL-Lite command MdigControl().
Using the auxiliary power supply
Matrox Meteor-II /Multi-Channel can supply power to your camera. Use the
4-pin power cable provided with your board to connect to the power supply of
your computer. The operating voltage can be set to either 5 V or 12 V, but the
current drawn by all cameras is limited to 1.5 A. The circuit uses an auto-resettable
fuse. For further information on connecting to the auxiliary power supply
connector, see the section, Connecting Matrox Meteor-II /Multi-Channel for PCI
to the auxiliary power supply input in Chapter 2, and Appendix B. Note that this
input is not available on the PC/104-Plus form factors.
Data interfaces
Video Interface ASIC
The Matrox Meteor-II /Multi-Channel board has a VIA, which acts mainly as a
video-to-PCI bridge. The VIA is capable of high-speed image transfers to Host
memory or other PCI devices across the PCI bus. It uses 4 Mbytes of video transfer
memory to store data until the PCI bus becomes available.
Matrox VIA can manage up to two simultaneous data streams. For example, it
can grab into video transfer memory, and concurrently transfer data over the PCI
bus.
The VIA is capable of separating image data into two or three, 8-bit components
(for example, RGB packed to RGB planar). This mechanism is also used to merge
line segments of monochrome multi-tap cameras.
