Matrox RadientPro CL acquisition section 35
UARTs
Matrox RadientPro CL 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.
PSGs
For each acquisition path, Matrox RadientPro CL features a programmable
synchronization generator (PSG). Each PSG allows for independent acquisition
from one video source, since each PSG is responsible for managing all video timing
and synchronization signals.
The PSGs are also responsible for managing the camera control and auxiliary
signals supported by the board. These signals are configurable signals that can
support one or several functions, one of which is user-defined for
Matrox RadientPro CL; the table in the next subsection identifies the functions
to which the camera control and auxiliary signals can be defined. The PSGs are
also responsible for implementing the functionality to which these can be defined.
*. 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.
