Appendix C.2. Communication protocol commands
There are several types of commands used for communication with sensor:
1. commands for requesting measured data and diagnosing (see Appendix C.2.1);
2. commands for controlling operating mode (see Appendix C.2.2);
3. commands for requesting factory settings and properties (see Appendix C.2.3);
4. commands for sensor configuring and span calibration (see Appendix C.2.4);
5. commands for configuring net address (see Appendix C.2.5);
6. commands for controlling power consumption mode (see Appendix C.2.6).

Always check command syntax before sending. Commands that are not
listed in this user manual are prohibited. Otherwise, it may result in
malfunction of sensor.

In earlier versions of the firmware, some commands are unavailable.
Appendix C.2.1. Commands for requesting measured data
There are five commands available for user to request concentration value. Primary
command to request measured data is <@*X> as it requires minimum power to process it.

Response description Command description
@ yes
yes
2 bytes in binary format (see
Table 8).
Returns sensor readings of scaled
concentration C
1
(not periodically,
single time only).
@*X yes yes
“@” symbol in ASCII format
and 2 bytes in binary format
(see Table 8).
Returns sensor readings of scaled
concentration
C
1
periodically
(every [1.28
± 0.065] ×
X sec),
where X is a value within the
range 0…9 in ASCII format).
CCS yes yes
5 bytes in ASCII format and
“0D” symbol. Returns sensor current ambient
temperature in Celsius degrees.
CFS yes yes
5 bytes in ASCII format and
“0D” symbol.
Returns sensor current ambient
temperature in Fahrenheit de-
grees.
CKS yes yes
5 bytes in ASCII format and
“0D” symbol. Returns sensor current ambient
temperature in Kelvins.
DATA yes yes
5 bytes in ASCII format and
“0D” symbol (see Table 9). Returns sensor readings of scaled
concentration C
1
.
DATAE yes yes
4 bytes in binary format and
“0D” symbol (see Table 10).
Returns sensors readings of
scaled concentration C
1
, status
byte and CRC value.
DATAE2 yes yes
5 bytes in binary format and
“0D” symbol (see Table 11).
Returns sensor readings of scaled
concentration C
1
, two status
bytes and CRC value.
