| Data Collection |
| Counter channels |
Channels 1 - 6 are always counter inputs:channels 1 - 3 dedicated for NRG #40 Maximum anemometer or compatiblechannels 4 - 6 use counter Signal Conditioning Modules (SCMs) to configure the channel for a particular sensor |
| Analog channels |
Channels 7 - 12 are always analog inputs:channels 7 and 8 dedicated for NRG 200P (potentiometer) direction vanechannels 9 - 12 use analog Signal Conditioning Modules (SCMs) to configure each channel for a particular sensor |
