Event Trace Data Definitions
XDC FLT1
Four binary digits, ABCD, where
A represents the Flow Differential narrow (FDn) transducer channel
B represents the Flow Differential wide (FDw) transducer channel
C represents the Flow Differential bi-directional (FDb) transducer channel
D represents the Airway Pressure (AP) transducer
and
1 = fault, 0 = okay
For example, 0100 represents a failed auto zero on the FDw channel.
HOME ER1
-1 or 1, where
-1 represents the clockwise direction
1 represents the counterclockwise direction
AD MMTCH, AD MTCH1
xx = A/D channel, where
0 = Flow Differential Narrow (FDn)
1 = Flow Differential Wide (FDw)
2 = Flow Valve Differential (FVd)
3 = Airway Pressure (AP)
4 = Oxygen Pressure (O2)
5 = not used
6 = Flow Valve Temperature (FVt)
7 = External Voltage (EV)
8 = Battery Voltage (BV)
9 = not used
10 = Flow Differential Bi-Directional (FDb)
11 = V ref/2 signal on power board
12 = V ref -ve signal on power board
13 = V ref +ve signal on power board
yyyy = signed difference of A/D 1 count – A/D 2 count
