| Two 8-bit 32
MHz A/D converters
The Domino Alpha 2 is equipped with two 8-bit A/D converters.
The maximum sampling rate of 32 MHz allows the board
to support double-speed cameras. This Domino frame grabber
also offers two 8-bit input look-up tables and a programmable
input filter (20, 10 or 5 MHz). The controls of the
gain and offset are programmable.
Camera and I/O connectors
The Domino Alpha 2 bracket offers two HD15 camera connectors
and one DB9 I/O connector. The HD15 connectors are compliant
with the Euresys-defined analog camera connector and
includes camera power supply. The DB9 connector incorporates
three external trigger and flash strobe TTL lines. These
connectors are compatible with the Domino Iota, simplifying
cable manufacturing.
Camera support
Beside standard CCIR and RS170 cameras, the Domino Alpha
2 also supports any kind of single-tap or dual-tap analog
camera, with progressive or interlaced scanning, synchronous
timing or asynchronous reset and asynchronous shutter
control. The high-resolution capability of the board
is compatible with top-notch cameras (mega- pixel cameras
are supported).
Two single-tap cameras can be used concurrently and
independently with one Domino Alpha 2. Each of them
has its own trigger and strobe line, and they acquire
their images into two separate buffers in the PC memory.
The board can share efficiently the two digitizing and
timing units between up to four single-tap cameras or
two dual-tap cameras.
A multi-mode synchronization system is available and
includes pixel clock and PLL locking. The Domino series
boards interface a wide range of cameras from various
manufacturers. An up-to-date list is available on the
Interfacing Cameras page.
On-board memory
Although it is able to transfer acquired images in real-time
to PC memory, Alpha 2 incorporates an 8-Mbyte on-board
frame buffer, ensuring that no image will be lost, even
when using the fastest cameras.
32-bit 33 MHz PCI bus
The Domino Alpha 2 is 32-bit 33 MHz PCI bus frame grabbers
with 3V or 5V signaling. Direct Memory Access and PCI
bus mastering are supported.
