COMMUNICATION PROTOCOL
1 General specification 1.1 Type of communication :
RS 232
SPEED:
9600/19200 Baud selectable
Parity:
NON
Stop Bit :
1
Data :
8 bits
Only Tx, Rx and GND pins are used with this protocol. Timeout = 100 ms. Interbyte timeout = 5 ms.
1.2 General command: FORMAT: : 1 byte type: CAPITAL LETTER from ‘A’ to ‘Z’ :
1 byte type: char between 0 and 255
:
String composed of bytes. Format is depending on the command.
: Calculated as follow :checksum = -(command + size + Σ (d(i)) ) modulo 0x100.
Checksum calculation example : Command example : “0x43 , 0x10 , 0x87 , 0x31 , 0x2E , 0x35 , Checksum” First add all data values : 0x43 + 0x10 + 0x87 + 0x31 + 0x2E + 0x35 = 0x16E Then calculate it complement : - 0x16E = 0xE92 Then : checksum = 0xE92 modulo 0x100 = 0x92 Be careful : this example of command is only an example and can’t be use to communicate with the gas bench.
Page 5
Technical manual cap3300
1.3 General answer FORMAT: : 1 octet type: CAPITAL LETTER from ‘A’ to ‘Z’ : 1 octet type: char between 0 and 255 : String composed of bytes. Format is depending on the command. : Calculated as follow :checksum = -(command + size + Σ (d(i) ) modulo 0x100.
NON ACKNOLEDGE COMMAND: (NACK ANSWER) An answer with only one data equal to 0x15 (NACK) has to be considered as a wrong command, a non defined command or a not available command.
1.4 DATA TYPE: In order to help the developer to fasten the design, the CAPBENCH can send the gas data in 3 different formats:
1.4.1 TEXTE format A data sent in text format takes 5 bytes and the value is coded directly in a string which can be displayed without any change. The strings is completed with space character 0x20 before the value. Ex: CO sent in text format will be received as :" 1.47". (display 1.47 % vol.) HC sent in text format will be received as :" 27" (display 27 ppm vol.)
1.4.2 Integer format Depending on the application, it may be helpful to reduce the time required to get the value by reducing the frames. For this reason, the data can also be sent in integer format. Each data in this case is received as an integer and has to be divided and put in a float depending on the resolution. Ex: CO at 2 digits: 1-The host receive 128 in the CO channel (coded in 2 chars: {0x00,0x80} ) 2-Divide by 100 3- display: 1.28 % vol. Ex: CO at 3 digits: 1-The host receive 1285 in the CO channel (coded in 2 chars: {0x05,0x05} ) 2-Divide by 1000 3- display: 1.285 % vol.
Page 6
Technical manual cap3300
1.4.3 Float format Coded on 4 bytes which can be cast in a float. If commands using float format has been chosen in your development, a 4 bytes string received has to be cast in float format. This example shows how to proceed in C language: Ex : { char RxDbuf[4]={0x40,0x00,0xA3,0xD7}; float *floatpt; float COval; floatpt=(float *)&(RxDbuf[0]); COval= *floatpt; /* at final, COval is equal to 2.01 %vol. in this example */ }
Other examples: CO2=12.9 %vol. will be coded on 4 bytes as : char RxDbuf[4]={0x41,0x4E,0x66,0x66}
HC=1498 ppm vol. will be coded on 4 bytes as : char RxDbuf[4]={0x44,0xBB,0x40,0x00}

2 List of the commands 2.1 Command ‘G’ : Set the baud rate This command set the baud rate to 9600 baud or 19200 baud. The new baud rate is applied once after using this command, receiving a positive answer and switching OFF and ON the bench. Command: Positive answer : . - Baud rate = 0x00
Serial communication set at 9600 (DEFAULT).
- Baud rate = 0x01
Serial communication set at 19200.
2.2 Command ‘O’ : Toggle PUMPS and SOLENOIDS This command changes the status of the pumps. Check the status bits to know if the pumps are running or not. Command: Answer if ok: . I/Ocommand and I/Ostatus format: b7:PUMP1 set to 1 if pump1 ON. Bit cleared if pump1 OFF b6:PUMP2 set to 1 if pump1 ON. Bit cleared if pump2 OFF b5: SOLENOID1 set to 1 if pump1 ON. Bit cleared if solenoid1 OFF b4: SOLENOID2 set to 1 if pump1 ON. Bit cleared if solenoid2 OFF b3:VACUUM SWITCH (READ ONLY) set to 1 in case of LOW FLOW b2:CO displayed at 3 digits b1:HC PROPANE display b0:reserved
2.3 Command ‘Z’ : Send a ZERO Command: Answer if ok : . Set all gas channels to 0 but O2 value to 20.9 %vol. A NACK command is returned if zeroing is already in progress or if the zeroing is not available.

2.4 Command ‘T’ : GET DATA AND STATUS in text format Command: Answer: . Each data is sent by a string of 5 ASCII codes in text format. The string can be easily displayed directly on your application.

2.7 Command ‘S’ : Start the continuous mode
This command is to set the gas bench in a mode which sends continuously the data frame selected. It is possible to decide the frequency of the transmission with the argument 'time'. Use the ‘Q’ command to leave a gas test to go back to the menu Command: Answer if ok and if dataformat=0: . Answer if ok and if dataformat =1: . Dataformat: Set to 0x00 if you want dataformat to be in text mode. (Format similar to 'T' command) Set to 0x01 if you want to receive data in integer mode. (Format similar to 'I' command) Set to 0x02 if you want to receive data in float mode. (Format similar to 'A' command) Datatype: Idem commands 'T', 'I' and 'A' . Datatype can be 0x20, 0x21, 0x22 or 0x15 depending on the data needed. Time: Value from 1 to 10. Giving the frequency of sending the frames. 1=100 ms. 10= 1000 ms.
2.8 Command ‘Q’ : Stop the continuous mode This command is used to leave the continuous mode data sending Command: Answer if ok : .

Note 1: Concentrations of CO, CO2 and HC send are stored in the EEPROM mapping at the 0x86 address. Note 2: The 3 points calibration is made at the factory. At any case, do not start again this calibration as it can falsify the measurements. Notice : keep a gas flow as long as the status bit “Calibration in progress” is active (about 5 secondes). When it is cleared, you can stop the gas flow. Example to calibrate CO=2.00% vol., CO2=13.0% vol. and HC=1500ppm vol. : < 0x43, 0x10, 0x87, 0x30, 0x32, 0x2E, 0x30, 0x30, 0x31, 0x33, 0x2E, 0x30, 0x30, 0x30, 0x31, 0x35, 0x30, 0x30, 0x4E>

2000ppm propane (C3H8), PEF=HighPEF. And between these two values, PEF is calculated with the following formula :
(HighPEF − LowPEF ) PEF = ×(HCpropane _ measured − HCpropane _ low)+ LowPEF ( ) HCpropane _ high − HCpropane _ low For example if HC=1500ppm propane (C3H8), PEF will be calculated with the formula above because 200ppm< PEF =1500ppm "Block pressure" + 6mBars so there is a leak. Otherwise if the pressure "Block pressure" < "Block pressure" + 6mBars so there is no leak. - Finally display the result of the leak test for the customer (“Leak detected” or “Leak absent”). Note that values 6mBars and 160mBars are adjusted to the CAPELEC gas analyzer. So create your own leak and ajust these values to detect it.

DATA lost in the EEPROM (bad checksum) Activated when the voltage of the O2 cell during the Bad O2 sensor The O2 sensor is damaged zero becomes under the limit (default limit is 4.0 mV and can be modified - stored in the EEPROM) Activated when the voltage of the NOX cell during a Bad nox sensor The NOx sensor is damaged calibration becomes under the limit Activated to inform that new values has been Sampling of new gas data New gas data value, temperature and pressure calculated on gas channels Activated after asking an Initial zero or an Install new IR emitter with the 'D' or 'U' command. Wait Initial Zero in progress Initial Zero in progress this bit to be cleared before to go back to measurement mode Activated to inform that new RPM values has been New rpm data Sampling of new rpm data updated Detector Low Signal
Lamp error
The EEPROM is failed
Normal signal amplitude can not be reached Problem linked with the IR source.
The signal of the detector is globally too low, coming from a bad detector or, an IR source too low or dirtiness inside the chamber. This bit is active when the consumption of the IR source exceeds its specifications or when the IR source is dead.

4.1 Lambda formula used internally The simplified BRETTSCHNEIDER formulae used to send a directly calculated lambda value is:. CO 1,7261 3,5 CO2 + + O2 + × − 0,0088 × (CO2 + CO) CO 2 4 3,5 + CO2 = 1,7261 − 0,0088 × CO2 + CO + 6 × HC × 10 − 4 1 + 4

)
(CO, CO2 et O2 are concentrations in %vol., HC is an Hexane value in ppm vol.) Even if the LAMBDA value send is a value between 0 and 9.999, it is recommended to display only this data when it is contained in the range [0.800-1.200]. In other cases, not display this data on your host user interface.
