RS485 Baud Rate:
0=1200;
1=2400;
2=4800;
3=9600;
4=19200 (default);
5=38400;
6=57600;

16-bit Integer
1
RS485 parity and stop bits:
0=8N1;
1=8N2;
2=8E1 (default);
3=8E2;
4=8O1;
5=8O2.
[N=no parity, E=even parity, O=odd parity]
16-bit Integer
2
Instrument address for the MODBUS-RTU protocol (1…247,
default=1).
16-bit Integer
3
Association of a physical quantity to the analog output 1:
0=PM1.0;
1=PM2.5 (default);
2=PM10;
12=CO
2
(only PMBsense-A).
The PM measurement is averaged according to what is set
with CPS command or MODBUS holding register 19.
16-bit Integer
6
Setting of the minimum value of the measuring range of the
physical quantity associated to the analog output 1.
(*)
If the output is associated to PM, the value is expressed as a
number of tenths (e.g. 5 = 0.5 µg/m
3
). If the output is asso-
ciated to CO
2
, the value is expressed as a number of units
(e.g. 200 = 200 ppm). The default value is 0.
32-bit Integer
8
Setting of the maximum value of the measuring range of the
physical quantity associated to the analog output 1.
(*)
If the output is associated to PM, the value is expressed as a
number of tenths (e.g. 50 = 5.0 µg/m
3
). If the output is as-
sociated to CO
2
, the value is expressed as a number of units
(e.g. 800 = 800 ppm). The default value is 10000 (=1000.0
µg/m
3
of PM).
32-bit Integer
10
Association of a physical quantity to the analog output 2:
0=PM1.0;
1=PM2.5;
2=PM10 (default);
12=CO
2
(only PMBsense-A).
The PM measurement is averaged according to what is set
with CPS command or MODBUS holding register 19.
