Analog Device

All analog devices are read into the computer using ADC channels located on one of two ADIO Industry Packs. Each ADIO has ADC inputs that may be differential (up to eight) or single-ended (up to sixteen) or a mixture. In the table below, ADIO channel #2.2+ refers to ADIO#2, channel 2+ (single-ended), while 1.3$\pm$ means ADIO#1, channel 3 (differential).
