Matrox Rapixo CL Pro acquisition 39
UARTs
Matrox Rapixo CL Pro offers an LVDS-compatible Matrox serial interface. Each
interface is mapped as a COM port so that it can be accessed through the Microsoft
Windows API. Each interface is comprised of both a transmit port and a receive
port, permitting the interface to work in full-duplex (bidirectional) mode. The
interfaces are located on the Camera Link connectors.
Each interface is controlled by a Universal Asynchronous Receiver-Transmitter
(UART)
*
. Each UART features independently programmable baud rates,
supporting all standard baud rates from 300 baud up to 115200

baud.
Acquisition Controller
The acquisition controller is responsible for reconstructing and storing image data
in main on-board memory. When writing data to memory, the acquisition
controller can perform line and frame reversal; it can flip the image horizontally
and/or vertically.
On Matrox Rapixo CL Pro DB/QB, the acquisition controller can write to four
non-sequential memory regions (zones) per acquisition path.
On Matrox Rapixo CL Pro SF/DF, the acquisition controller can write to the
following number of non-sequential memory regions maximum: 6 for Medium,
8 for Full, 9 for 72-bit, and 10 for 80-bit
‡
.
Note that the width of each region must be a multiple of the number of taps in
that region.
To establish the number of non-sequential memory regions to which your video
source must write, refer to the documentation accompanying your video source.
*. The UART implementation was derived from a design by Daniel Wallner. Please see

†. In addition, the maximum baud rate is highly dependent on the amount of computer
resources available.
‡. The 10 non-sequential memory regions in 80-bit configuration are only available with
8-bit taps.
