10 ST-133 Controller Manual Version 3.B
High Speed Data Transfer: Data is transferred directly to the host computer memory
via a high-speed interface (TAXI or USB 2.0 protocol) link. A frame buffer with standard
composite video, either RS-170 (EIA) or CCIR, whichever was ordered, may also be
provided. The digital data at the output of the A/D converter is then transferred at high
speeds to the host computer.
For the TAXI protocol, a proprietary PCI card places the data from the controller directly
into the host computer RAM using Direct Memory Access (DMA). The DMA transfer
process ensures that the data arrives at sufficiently high speed to prevent data loss from
the controller. Since the data transfer rate is much higher than the output rate from the
A/D, the latter becomes the limiting factor for the data acquisition rate. Once the digital
data is in RAM, the image acquisition program can transfer the image into its own
working RAM for viewing and further processing.
Applications: With its small size, fully integrated design, support for a variety of
cameras, CCD arrays, and computers, temperature control, advanced exposure control
timing, and sophisticated readout capabilities, the ST-133 Controller is well suited to
both general spectroscopy, macro imaging and microscopy applications.
