Programmable Analog Output Diagrams
With the serial communication you can use the following
windows:
Win 163
Win 224
Win 257
Win 267
The windows from 136 to 140 manage an additional set point
(set point 3) dedicated to turn ON or OFF the gauge (win 267=4)
226/300
Pressure measurement unit
(0=mbar, 1= Pascal, 2=Torr)
Pressure reading with the format X.X E
XX
Gauge status (read only):
0  when a gauge is not connected
1  when a gauge is connected
2  when the pressure read is under
3  when the pressure read is under
4  when the "identification" is present
Gauge power (read/write):
If you need to turn off the gauge at
certain condition you can use this
window
0  gauge off
1  gauge on (default)
2  gauge normally off. It turns on when
the set point 1 is activated. If the set
point 1 type (win 101) is selected as
"pressure" the gauge is always on.
3  gauge normally off. It turns on when
the set point 1 is activated. If the set
point 2 type (win 171) is selected as
"pressure" the gauge is always on.
4  gauge normally off. It turns on when
the set point 1 is activated. If the set
point 3 type (win 101) is selected as
"pressure" the gauge is always on.
