public class CO2SubsystemMonitor
extends PolledInstrumentService
implements Instrument, InstrumentDataListener, CO2SubsystemMonitorIF

reads and writes the B&B 232SPDA module used to interface various analog and digital signals from within the CO2 electronics housing. It has seven 12-bit A/D inputs, four 8-bit D/A outputs, two digital inputs and one digital output. It is powered by +12Vdc and is communicated to via an RS-232 connection. It is serial port #yy and it's serial parameters are xxxx,x,x,x with xx hardware control. See appendicies for specific command structures. Analog In #0: Volt_24V This is a scaled version of the main +24Vdc bus. The input range is a DC voltage from 0 volts to 5 volts, which maps to an input voltage range of 0 to +30V. The defining equation is y (Bus volts) = 6.0x (ADC volts). Analog In #1: Curr_24V This is a representative voltage of the current used by the +24Vdc bus. The input range is a DC voltage from 0 volts to 5 volts, which maps to an input current range of 0 to 10A. The defining equation is y (Bus amps) = 2.0x (ADC volts). Analog In #2: HTM2530 Humidity This is the ambient humidity inside of the FOCE electronics can. It outputs a 1-4V signal which corresponds to 0-100% Relative Humidity (RH). The defining equation is y (%RH) = 37.5 x (ADC volts) - 37.5. Analog In #3: HTM2530 Temperature This is the ambient temperature inside of the FOCE electronics can. It outputs a 0 to 5V signal which corresponds to a -40 C to +125 C temperature range. There are two possible defining equations, a more precise third order polynomial and a simpler linear equation. The linear equation works sufficiently around our expected operating range but generates considerable errors at either extreme. Third Order: y = 7.689x^3-48.935x^2+137.49x-132.34 Linear: y = 40.944x - 73.787 where y is the measured temperature in degress Celsius x is the ADC volts Analog In #4: Fan State This signal is actually a digital input signal used to indicate the stae of the cooling fan. High = Fan OFF, Low = Fan ON. Analog In #5: Reserved for future use Analog In #6: Reserved for future use Digital In #0: Water Sensor #1 This is a digital input signal tied to water detector #1. A digital high indicates no water present, while a digital low indicates water in the housing. Digital In #1: Water Sensor #2 This is a digital input signal tied to water detector #2. A digital high indicates no water present, while a digital low indicates water in the housing. Digital Out #0: Fan Control This is a digital output signal used to control the state of the cooling fan. Setting this bit high activates the fan, while a low de-activates the fan. Analog Out #0-#3: Not Used These signals are not brought out to the Power Monitor Board.
