Operating several
FireStingO2
in parallel
The fiber-optic oxygen meter
FireStingO2
is available as 1-, 2-, or
4-channel version. However, in order to realize extendable
multichannel systems with higher channel numbers (e.g. 8, 16, 32,
or 64), several
FireStingO2
meters can be easily operated at a
single PC as described in the following:
Connect each
FireStingO2
to a free USB port of your PC. If the PC
does not provide a sufficient number of USB ports, you can use an
external USB-hub. Ensure that the USB-hub provides sufficient
power (each
FireStingO2
needs max. 70 mA); an external power
supply for the USB-hub might be advisable.
The
Pyro Oxygen Logger
software has now to be started
separately for each connected
FireStingO2
. So, if you want to
operate e.g. 6 different
FireStingO2
meters, you have to start the
Pyro Oxygen Logger
software 6 times, which will open 6
Pyro
Oxygen Logger
windows on your desktop. The different windows
operate completely independent from each other, and are
associated to exactly one of the
FireStingO2
meters. In order to
check which window is associated to a specific
FireStingO2
, simply
press the
Flash Logo
button in the main window of the
Pyro
Oxygen Logger
software, which induces a flashing of the red
FireSting
logo on the associated device for about 1 sec.
When closing the
Pyro Oxygen Logger
software, all settings and all
current calibration data are saved in a "setup file", which is
automatically loaded at the next startup. This setup file is saved
specifically for each
FireStingO2
serial number, i.e. each
FireStingO2
in the above described setup keeps its own settings
and calibration data.
