LonWorks® Output Network Variables
nvoAI	Sensor output. 0%=0 ppm, 100%=200 ppm. Values can be rescaled using nviCalibVal input network variables. Returns +163.83% on input fault condition.
nvoDI	Sensor output interpreted as a discrete. Return ST_OFF if input is below nciDILow and ST_ON if input is above nciDIHigh. ST_Nul is input fault condition.

LonWorks® Input Network Variables
nviCalibrate	00 – Zero Cmd. Current sensor output = 0%. 01 – Span Cmd. Current sensor output = 100%. 02 – Calibrate Value #1. Current sensor output corresponds to lower value which is nviCalibVal. 03 – Calibrate Value #2. Current sensor output corresponds to upper value which is nviCalibVal. 15 – Reset calibration to factory defaults.
nviCalibVal	See nviCalibrate for description. Use with command 02 and 03.

Lonworks® Configuration Network Variables
nciAIOffset	Offset to be added to nvoAI before sent onto the network.
nciMinDelta	Minimum change required before a network update.
nciMinSendT	Minimum elapsed time before a network update is sent.
nciMaxSendT	Maximum elapsed time before a network update is sent.
