6 Using
two
SCP1000
demo
kits simultaneously
In some applications, such as air conditioning controlling or air flow measurements, differential
pressure measurement is required. To support these kinds of applications two (or even more)
SCP1000 demo kits can be used simultaneously on one PC.
In order to use two SCP1000 demo kits simultaneously follow the steps below:
1. Install the GUI software and USB driver as instructed above (see section 2).
2. Connect the 1
st
SCP1000 demo kit to PC.
3. Start the GUI software.
4. When the 1
st
SCP1000 demo kit and it's GUI software is running, connect the 2
nd
SCP1000
demo kit to PC.
5. Install the USB driver if required (the USB driver has to be installed separately for each
USB port, see instructions in section 2).
6. Find the location of the SCP1000 demo kit GUI software exe-file (the default installation
path is C:\Program Files\SCP1000-USB-DEMO-VER.2.5).
7. Copy the file "SCP1000-USB-DEMO-VER.2.5.exe" to other name (for example
"Copy of SCP1000-USB-DEMO-VER.2.5.exe").
8. Start the GUI software for the 2
nd
SCP1000 demo kit by running the
"Copy of SCP1000-USB-DEMO-VER.2.5.exe".
When both demo kits are connected to one PC, the SCP1000 data can be logged to separate files
as instructed in section 4.1.3. If the both demo kits are used for data logging purposes, the data
can be synchronized with the time stamp in the result file (time is from the PC's system clock). The
Windows HyperTerminal can also be used with two SCP1000 demo kits (open own HyperTerminal
connection for each demo kit).
Please notice, that the two demo kits may not work simultaneously if they are connected to PC via
an USB hub (in such case, try connecting the demo kits directly to PC with out USB hub).
