From Maslab 2011
The gyro is an ADXRS300 (google for datasheet) and the board is manufactured by Intempco (http://www.intempco.ca/index.php3?country=can&language=en&content=products§ion=motion), 0 to 5V output with 2.5V being center equal to no rotation.
See the Orc Manual, section 4.3. You can either make a cable as shown there, or (carefully!) solder one piece of female header to a position in the fourth row of the I/O pins on the orcboard, so that you can plug it in directly. The fourth row is also signal, and is connected directly to the third row.
