http://www.sgi.com/products/appsdirectory.dir/Applications/Peripherals/ApplicationNumber5698.html (Silicon Surf Promotional CD, 01/1995)The CerealBox(R) is a simple data acquisition system which makes it easy to capture external analog and digital signals on an SGI workstation. It consists of a small box into which the external voltages (0 -5 Volts) are supplied. These inputs are converted at 12-bit resolution and transmitted via RS-232 to the host.
The one to eight analog inputs can be selected, and 0, 8, or 16 input discretes can also be sampled. The baud rate is selectable in software. Source code is provided.
The data is not subject to noise on the serial line, and the CerealBox does not require a VME board or device driver.
