If you download the Control Systems User Manual from Innovation First's website you will find several spreadsheets in the manual that not only list the pinouts for the RC and the OI but what functions they take in the software, the variable names and in some cases disable info. This manual is a must for all teams to have a hard copy of and the electrical and software teams should have copies of their own for reference.
