Appendix B – EC9800 Protocol
DCONC
Function Sends the current instantaneous concentration data to the serial
port.
Format DCONC,{<DEVICE I.D.>}{TERMINATOR}
Device response {GAS}<SPACE>{STATUS WORD}<CR><LF>
All numbers are in floating point format. The STATUS WORD indicates the
instrument status in hex using the following format:
Bit 15 = SYSFAIL (MSB)
Bit 14 = FLOWFAIL
Bit 13 = LAMPFAIL
Bit 12 = CHOPFAIL
Bit 11 = CVFAIL
Bit 10 = COOLERFAIL
Bit 9 = HEATERFAIL
Bit 8 = REFFAIL
Bit 7 = PS-FAIL
Bit 6 = HV-FAIL
Bit 5 = OUT OF SERVICE
Bit 4 = instrument is in zero mode
Bit 3 = instrument is in span mode
Bit 2 = unused
Bit 1 = SET→PPM selected, CLEAR→MG/M3
Bit 0 = reserved (LSB).
DSPAN
Function Commands the unit under test to enter the span mode and stay
there.
Format DSPAN,{<DEVICE I.D.>}{TERMINATOR}
Device response <ACK> if the unit under test is able to perform the command,
<NAK> if not.
DZERO
Function Commands the unit under test to enter the zero mode and stay
there.
Format DZERO,{<DEVICE I.D.>}{TERMINATOR}
Device response <ACK> if the unit under test is able to perform the command,
<NAK> if not.
ABORT
Function Commands the addressed device to abort the current mode and
return to the measure mode.
Format ABORT,{<DEVICE I.D.>}{TERMINATOR}
