Running Multiple Instances of SI_SCOPE in Windows
You can configure SI_SCOPE to analyze more than one RS232
channel from the same PC. In order to do this you must configure the second
instance of SI_SCOPE to use the standard Windows serial driver and you will need
to launch it from the command line. To operate SI_SCOPE in a multi-channel
environment from the same Windows PC do the following:
- Create a directory on your hard drive named "Channel2"
or some other name.
- Copy the files si_scope32.exe and WinApiDrvr32.dll from
the SI_SCOPE install directory to the directory Channel2.
- Bring up the first instance of SI_SCOPE using the
ScopeCfg program as normal. You can have this first instance configured to use
SI_SCOPE's serial drivers or you can have it configured to use the standard
- Open a command prompt and navigate to the directory you
created in step one.
- Launch the second instance of SI_SCOPE as follows
si_scope32 /drvr:winapidrvr32.dll /p1:x /p2:y Where
x and y are the windows port numbers for the communications ports you are
using to monitor the second channel. For example if you wanted to use COM5 and
COM6 on your system you would pass /p1:5 /p2:6
on the command line. Note that these ports cannot be the same as those being
used to monitor the first channel.
You can repeat the process for as many channels as you
wish to monitor as long as you run each instance of SI_SCOPE from within its own
Before utilizing this technique please consult the
following document regarding the difference between running SI_SCOPE with the
standard Windows driver vs. SIDRVR:
