IQM 60 V5 Pump Revision October 2010

Reserved * b1 reserved no meaning at all
PumpStatus
* b2 = 1 pump failed
(This bit function only apply for O3 sensors
with pump)
* b2 = 0 pump working well
NO2_Scrubber * b3 = 1 NO2 scrubber temperature too low, otherwise, works well (This bit only
related with NO2 sensor).
ZeroScrubber * b4 = 1 zero air scrubber turned on, otherwise, its off
Reserved
* b5 reserved no meaning at all
Reserved * b6 reserved no meaning at all
Reserved * b7 reserved no meaning at all
AQM_STATUS
* 8 bits (b7b6b5b4b3b2b1b0) monitor configuration status information
* b0 = 0, means the AQM gas reading unit is ppm
* b0 = 1, means the AQM gas reading unit is mg/m3
* b1 ~ b7 reserved
OPERATION_STATUS
* 8 bits (b7b6b5b4b3b2b1b0) monitor operation status information
* b0 = 0, means the AQM will only report data by polling individual sensor
* b0 = 1, means the AQM will auto report all sensor concentration at specified
rate.
* b1 = 0, means the AQM will only do zero calibration by user command
* b1 = 1, means the AQM will auto do zero calibration at specified
ZERO_CAL_INTERVAL.
* b2 = 0, means the AQM will not do auto zero readings.
* b2 = 1, means the AQM will do auto zero readings at specified
AUTO_ZERO_READ_FREQ
time intervals. The zero reading time is fixed 15 minutes long.
* b3 ~ b7 reserved
Section 3.
Data value format representation:
The floating point data values use standard IEEE754 32 bits floating point little ending
representation, like DATA field.
Section 4.
Data transfer mechanism
1. Due to the monitor main chips feature, 2 byte int and 4 bytes float data send sequence are
low byte first, high byte last.
2. For regular data report:
Once the monitor power on and after warming up (1 minute), it will regularly report measured result
to RS232 serial port by default.
Section 5. RS232 communication port settings:
Baud rate:
38400
