Table 6. Sensor operating commands
Command in
OEM mode
Available in
USER mode
Command name Response Description
@ Yes Requests of concentration. see Table 8
Response in HEX. The command @ is 16-bit concentration data. The
lead byte Conc1H transmitted first, low byte Conc1L at the end of
response.
@*X Yes Periodical request of concentration. see Table 8
Response in HEX. The command @*X is initiate regular transmitting
of gas concentration data to UART. Here X -
is a value in range 0…9
(ASCII) proportion to standard operating period of the sensor (1.3
sec).
DATA Yes Request concentration readings.
ASCII 5-
digits and
0Dh
The response is the concentration in %Vol * 100. i.e. response 00198
means 1.98%Vol.
DATAE Yes
Request concentration, status byte
and check sum.
HEX 4-bytes
and
0Dh
Bytes #1…2 are the concentration data (similar to
@ -response), byte
#3 is the status byte, byte #4 - ControlSum^EveryByte .
DATAE2 Yes
Request concentration, double status
byte and check sum. Response in
HEX.
HEX 6-bytes
and
0Dh
Bytes #1…2 are the concentration data (similar to
@ -response),
bytes #3…4 are the status bytes, byte #5 -
ControlSum^EveryByte .
CCS Yes
Request of concentration,
temperature in Celsius degrees and
status word.
ХХХХХ

CFS Yes
Request concentration, temperature
in Fahrenheit degrees and status
word.
ХХХХХ

ХХХХХ
is gas concentration, YYYYY is temperature value in
Fahrenheit, ZZZZZ is the status byte.
CKS Yes
Request concentration, temperature
in Kelvin degrees and status word.
ХХХХХ
YYYYY
ZZZZZ
ХХХХХ YYYYY ZZZZZ
separated with space symbol (20h) in ASCII.
ХХХХХ
is gas concentration, YYYYY is temperature value in Kelvin,
ZZZZZ is the status byte.
CONST No Request of sensor constants.
The response includes the constants stored in sensor memory and
used for troubleshooting. The response format available by request.
See chapter C.5 for details.
CONST2 No
Request of sensor constants from the
special memory space.
F Yes
Detailed information about working
condition of the sensor.
see Table 7
Response on F command is 5 byte in ASCII separated by (09h).
