Meaning:
Rapidox is still initialising
Response:
!Sensor heating[CR][LF]
Meaning:
Rapidox is still heating sensor to operating temperature
Response:
!Sensor cooling[CR][LF]
Meaning:
Rapidox is still cooling sensor to operating temperature. This can
happen when switching from Normal to Helium operating mode.
Response:
!Cleaning sensor[CR][LF]
Meaning:
Rapidox has finished heating sensor and is cleaning the sensor for 5
seconds
Response:
!User setup active[CR][LF]
Meaning:
The configuration menu has been activated via the front panel
keypad. The menu will automatically time out 60 seconds after the
last key was pressed, or press the keypad’s ESC key to return
immediately to normal run mode.
Response:
!Possible sensor fault[CR][LF]
Meaning:
The sensor has failed to reach operating temperature within 10
minutes from power up. This may be due to the age of the sensor, or
because a high thermal conductivity gas is being used.
Response:
!No sensor or sensor fault[CR][LF]
Meaning:
Sensor is not connected, or there is a fault in the sensor
Response: d2.959E+05,-1.426E+01,2.000E+00,,23:19:40,14/01/00,,,ALM1&2
,0[CR][LF]
Meaning:
“d” means data is being sent
“2.959E+05” is Oxygen reading in ppm
“,” = data separator
“-1.426E+01” is Oxygen sensor reading in mV
“,” = data separator
“2.000E+00” is the internal pressure sensor reading in bar (gauge)
“,” = data separator
“23:19:40” is Rapidox time
“,” = data separator
“14/01/00” is Rapidox date in DD/MM/YY format
“,,,” = data separators
“ALM1&2” means both alarm conditions 1 and 2 exist *
“,” = data separator
“0” = sensor state code (0=OK, 1=O
2
O/Range, 2= O
2
U/Range, 3=O
2
Fault, 4=Press. U/Range, 5=Press. O/Range, 6= Press. Fault**)
[CR] = ASCII 13 (Carriage Return character)
[LF] = ASCII 10 (Line Feed character)
*
If no alarm conditions exist, this data is empty, so the response would look like d2.959E+05,-
1.426E+01,2.000E+00, ,23:19:40,14/01/00,,,,0[CR][LF]
**
These are binary codes so fault combinations produce other numbers
