4.4.4.3 Examples
The string PI001<CR> will program a unit to the I.D. of 001.
The string PI001 123 will program a unit to the I.D. of 001 with a serial
number of 123.
The string PI003 004 will program an EC9830 for a main ID of 003 and a
secondary ID of 004.
4.4.5 Serial Command Set
This section describes the Bavarian Network and 9800 command sets available on
the EC9830 using the instrument Command mode.
4.4.5.1 Bavarian Protocol Command Set
Command
{DA}
Function
Bavarian network command that returns the current instantaneous concentration.
Format
<STX>{DA}{<DEVICE I.D.>}<ETX><BCC1><BCC2>
Device response
<STX>{MD}{01}<SP><kkk><SP><+nnnn+ee><SP><ss><SP><ff><SP><mmm><SP>
{000000[0000]}<SP><ETX><BCC1><BCC2> where:
kkk = instrument ID
+nnnn+ee = instantaneous gas concentration in ppb or mg/m3
ss = status byte for both channels with the following bit map (positive logic):
D0 = unused
D1 = out of service
D2 = instrument is in zero mode
D3 = instrument is in span mode
D4 = unused
D5 = unused
D6 = units (1 = ppm, 0 = mg/m3)
D7 = instrument is performing a background cycle.
ff = failure byte for both channels with the following bit map (positive logic):
D0 = flow sensor failure
D1 = instrument failure
